What to Expect When You’re Expecting Your Tesla

(Essential reading for new owners and a handy review for existing Tesla drivers.) Written by Pete Petrovsky

If this is your first EV or first Tesla, congratulations on taking the first step towards helping to accelerate the world’s transition to sustainable energy with a car that is completely changing the entire automotive industry for the better. You’ll be glad to know you’ve ordered the world’s safest car, which is an absolute pleasure to own and drive and you can wave Goodbye to petrol station visits and most servicing.

Did you know Tesla doesn’t have a mandated service schedule? That said, there are a couple of recommendations. How much will servicing your Tesla set you back? In Australia, the Tesla recommended servicing and maintenance will cost $111 in the first three years compared to $1,725 or about 15 times as much for an average Australian internal combustion engine vehicle over the same 3-year period. But that’s just where the savings begin. Did you know that even if petrol was free, you would still be better off with a Tesla? To find out how far ahead you can expect to be after three years see: https://www.tocwa.org.au/2021/11/26/tesla-model-3-economics-compared-to-an-average-australian-petrol-car/

With all that enjoyable, safe and low-cost motoring to look forward to, you’re no doubt eager to hit the road, but perhaps you’re wondering whether you know everything you should before jumping behind the wheel of your shiny new Tesla. While I aimed to be comprehensive, the following should not be considered an exhaustive list of everything there is to know about owning an EV, but hopefully it should make for a good and informative start.

Paying For Your New Tesla

There have been a couple of instances in Australia where reservation holders had their email accounts hacked and consequently, while under the impression they were transferring their funds to Tesla, instead, they were unknowingly making the transfer to a scammer. I believe Tesla has now put in place various measures such as using your car’s VIN number as the account number but a good tip is to first transfer a negligibly small amount and check with Tesla that they received your funds and then use the exact same account details to transfer the balance. This is the method I used for our first Tesla in September 2019 and it worked well, however, with there now being a considerable backlog, you’ll need to allow enough time to ensure you are ready to take delivery as soon as your car is ready, otherwise you may run the risk of being pushed back in the queue as your car may be reassigned to the next reservation holder for that model car and trim. Please note, if you’re financing your Tesla and your bank or other loan provider is making the transfer for you this may not be an issue, but if you are going to be transferring the balance owing on your car yourself it pays to be cautious as you may not get a second chance.

Insurance

You’ll want to ensure you take out comprehensive car insurance before driving your new Tesla for the first time. There are numerous variables that go into determining insurance premiums including the insured value, the excess, where and how the car is parked, your driving history, your demographics, the age of the youngest driver, your no claims bonus, personal versus business use, how much you expect to drive the car as well as optional extras such as a hire car and so on. It’s important you take these and any other relevant factors into account when arranging your car insurance. In terms of who are the most Tesla and EV friendly insurers in Australia, TOCWA members report the lowest premiums from RACWA and Budget Direct ranging between approximately $900 a year or lower to about $2,000 a year or more for a Model 3, but please do shop around as far and wide as you feel appropriate and please let us know if you happen to find better like-for-like rates with another insurer. [2023 Update: Model Y premiums seem to be fairly similar the Model 3 amounts quoted above.] [2024 update: Koba Insurance says they specialise in smart EV insurance including pay-per-KM insurance where you can grant them remote access to your car. We haven’t had enough experience or feedback from our members to form an opinion on this product as yet but I’ll update this article once we do.]

Vehicle Delivery

Before picking up your car I recommend that you download the Tesla app here: https://www.tesla.com/en_AU/support/tesla-app and set up an account. Tesla may have already let you know that the delivery experience will be fairly fast, possibly as short as 5-15 minutes. You may therefore want to consider reaching out to an experienced Tesla owner to run you through the controls and settings before you drive off for the first time. Alternatively, please see this video about how to best set up your new Tesla. I generally recommend setting the car up with the following options turned on:

  • ◦ Lights – Auto
  •  ◦ Auto High Beams – [2024 update: In May 2024, Tesla updated our cars with Adaptive High Beams via a free over-the-air update. In my experience, the adaptive high beams seem like a great safety feature and hence I’d recommend enabling them on all cars with Matrix (Global rather than SAE/ECE) Headlights. All Australian Model Y vehicles and most if not all Shanghai-built Model 3 cars after about Q4 of 2021 have matrix headlights and I believe if Tesla needs to replace headlights on older models they replace them with the new matrix headlamps.]
  •  ◦ Windscreen wipers – Off or Auto [2023 Update: The algorithm has improved so now it’s more of a personal choice.]
  •  ◦ Regenerative Braking – Standard
  •  ◦ Stopping Mode – Hold (This is the single pedal driving feature. It can take a few hours of city driving before it becomes automatic or instinctive but once you get used to it you will most likely won’t want to drive in any other mode.)
  •  ◦ Charging – 80% for cars with NCA batteries and 100% for cars with LFP batteries [2023 Update: As per Tesla guidelines, the original article recommend 90% but Tesla has changed this recommendation to 80%.] (Standard Range and Rear Wheel Drive cars have LFP batteries and Long Range and Performance variants have NCA batteries. To check for yourself, navigate to the charging menu and if you see the words Daily and Trip on the State of Charge scale your car has NCA batteries. If it just shows percentages you have an LFP battery. )
  •  ◦ Settings under the Autopilot Menu:
  •  ◦ Set speed – Current Speed
  •  ◦ Automatic Blind Spot Camera – Enabled
  •  ◦ Blind Spot Collision Warning Chime – Enabled
  •  ◦ Forward Collision Warning – Early
  •  ◦ Lane Departure Assistance – Assist
  •  ◦ Emergency Lane Departure Avoidance – Enabled
  •  ◦ Automatic Emergency Braking – Enabled
  •  ◦ Obstacle Aware Acceleration – Enabled
  •  ◦ Traffic Aware Cruise Control Chime – Enabled
  •  ◦ Green Traffic Light Chime – Enabled
  •  ◦ Walk-Away Door Lock – Enabled
  •  ◦ Driver Door Unlock Mode – Enabled
  •  ◦ Car Left Open Notifications – Enabled
  •  ◦ Lock Confirmation Sound – Enabled
  •  ◦ Close Windows on Lock – Enabled
  •  ◦ Display – Auto
  •  ◦ Brightness – Auto
  •  ◦ Trips – Rename the last trip meter to: “Lifetime – Do Not Reset!”
  •  ◦ Trips – Rename the second last trip meter to “New Tyres”
  •  ◦ Trip Planner – Enabled
  •  ◦ Online Routing – Enabled
  •  ◦ Sentry Mode – On (Remember to turn back on after a software update. Please note, Sentry Mode consumes about 200 Watts per hour or about 4.8kWh over a 24 hour period. Sentry Mode is automatically turned off once the state of charge drops to 20%.) [2024 Update: Tesla has announced Sentry Mode power consumption optimisations which will soon reduce the power draw of this feature .]
  •  ◦ Dashcam – Auto and On Honk (Remember to turn back on after a software update.)
  •  ◦ PIN to Drive – Enabled
  •  ◦ Glovebox PIN – Enabled
  •  ◦ Cabin Overheat Protection – On (Please note this will be automatically disabled when the battery state of charge drops below 20%)
  •  ◦ Software Update Preference – Standard

TOCWA

At any time, but ideally prior to taking delivery of your vehicle, I would encourage you to become a TOCWA (Tesla Owners Club of Western Australia) member. TOCWA is the officially sanctioned Tesla club for WA and a not-for-profit volunteer-run group facilitating communication, advocacy and community for Tesla Owners and reservation holders within WA. 

TOCWA is always willing to help anyone considering buying an EV but for best value I would urge you to become TOCWA member as the cost is just $20 a year and I’d be surprised if you don’t get this back several times over. Firstly, as a member you will be invited to join the weekly ‘Ask Us Anything’ Zoom call run by the Club Secretary where you’ll get the opportunity to have your questions answered by veteran Tesla owners with years of invaluable experience. The Club Secretary and Chairman who are among some of the first Tesla owners in Australia, have, as at 2022 driven well over 200,000 kilometres in each of their Teslas around WA as well as on trips across or around Australia and they and many other members are always happy to share their years of experience. [2024 Update: Both have now driven over 300,000 kms.] You’ll also be invited to monthly in person Casual Meet Ups and many other events as well as being able to borrow charging equipment, spare tyres for long road trips and other equipment at no cost. You will also be able to purchase some chargers and other accessories at substantially discounted prices. Being a not-for-profit organisation, the club is able to buy in bulk or at wholesale prices and offer the items to members at no mark-up. For full disclosure, I am a proud TOCWA committee member. To join the club please visit: https://www.tocwa.org.au/membership-join/

Synergy EV Home Plan

Once you’ve taken delivery of your Tesla, I recommend signing up for Synergy’s EV tariff ‘trial’. If you’re still on the Synergy A1 tariff your electricity rates won’t change apart from between the hours of 11PM to 4AM during which time your tariff will drop by about 30% from currently 29.3273 cents to 20.4651 cents. Whether you charge your car during this time or not, the tariff applies to your entire home’s electricity draw. If you are on any tariff other than A1, please give me a call to determine the best course of action. 

In order to qualify for the Synergy EV Home Plan, you’ll need to provide proof of ownership but the car cannot be registered in a business name.

[2023 Update: Synergy no longer offers the the EV Tariff trial, instead they offer the ‘Electric Vehicle Add On’]

Plugshare and Charger Network Apps

A must for all EV owners is the Plugshare App which lists most if not all EV chargers available to the public in Australia and around the world. The browser based version can be found here: www.plugshare.com and these are the Apple iOS and the Google Android versions.

An alternative is A Better Route Planner which can be found here: https://abetterrouteplanner.com/ and these are the Apple iOS and the Google Android versions of the app.

You may also wish to download the following EV charging network apps and set up an account and a payment method such as a credit or debit card so that when you arrive at one of these chargers you can plug and charge without stress or wasting time worrying about setting up an account and linking a credit card.

Chargers, Cables and Adaptors

Only cars ordered before 9th July 2022 will come with an included UMC (Universal Mobile Connector) which will work on a standard 10A home powerpoint. It will also come with a 15A adapter also known as a “pig tail” and you can also purchase other after-market tails such as the 32A, 5-pin, 3-phase one, which among many other places, can be found here: https://www.evseadapters.com/products/australia-32a-5-pin-adapter-for-tesla-gen-2/ or https://braumach.com.au/products/tesla-model-3-y-20a-gen-2-mobile-charger-cable-adapter-2017-22-aust-stock? [2024 update: expect to pay no more than about $200. If the price is more, there are now plenty of outlets that may offer cheaper pricing.] There’s a good chance you won’t need this 3rd tail which should generally not be used in off-grid generator-powered situations, but if in doubt please feel free to reach out to TOCWA for advice.

For a faster, permanently wired and wall-mounted home charging solution, you can consider the Tesla HPWC (High Power Wall Connector) See: https://www.tesla.com/en_AU/support/home-charging-installation/wall-connector The HPWC is very reasonably priced but the installation pricing from the installers listed on the Tesla website is exorbitant, in my opinion. If you require an installer, or if you’d like to discuss other charging options please feel free to contact me and I’ll try to put you in touch with a reasonably priced installer in your area.

For charging at untethered public AC chargers you will require a Type 2 (a.k.a. Mennekes) EV cable which can be purchased from Tesla here. It can also be bought from other retailers, however, please note, these cables can come in various power ratings and length configurations. I recommend the 22kW 7.5-metre version. Although a 5-metre cable is considerably cheaper, it’s not uncommon to find yourself “ICED” which is where the EV charging bay is blocked by an ignorant or inconsiderate driver of an internal combustion engine (ICE) vehicle. In these situations, the 7.5-metre cable should be long enough to reach an adjacent parking bay.  

For more great information about charging your Tesla please see the following article: https://www.tocwa.org.au/advice/charging/

Accessories

If you’re interested in buying accessories for your new Tesla, I highly recommend attending the TOCWA Ask Us Anything teleconference call and speaking to the existing Tesla owners first. In terms of vendors, this is the link to the official Australian online Tesla store: hhttps://shop.tesla.com/en_au There are also now many third-party vendors. The two main Australian sites seem to be: https://tesloz.com.au/ and https://tessories.com.au/ but you can also explore Amazon and many other online shopping sites.

EV Knowledge

As a new EV owner there will be some new information you’ll want to take on board, including charger knowledge, public charging etiquette, and lots of Pro Tips that you will find helpful. As a minimum, it’s good to know about the ‘ABCs’:

  • Always Be Courteous

Electric vehicles are a disruptive technology and although it’s becoming rare, you may come across some people whose livelihoods or whose belief system or identity may be threatened by the rapid shift to sustainable transport. You may also find yourself ICED or there may be other situations where you’ll be tempted to let the person know exactly what you think, however, it is always best to remain calm, respectful and courteous and if all else fails it may be best to prevent any escalation and walk away. Please also remember that being an EV owner and/or an EV driver you’re representing other EV drivers and the wider EV community.

  • Always Be Charging

Owning an EV is in many ways similar to owning a smartphone. There’s nothing worse than a dead phone and although it’s extremely rare for a Tesla to ever run out of charge you don’t want to find yourself in that situation so it’s a good idea to plan your longer journeys around charging points and to always have a contingency plan because you could get to a charger only to find it’s not working or taken up by another EV.  

Although this is changing at a fast pace, you will soon learn that with Teslas still being a relative novelty, it’s not uncommon to be stopped by a curious member of the public who is fascinated by your Tesla and is eager to ask you about your experience. (The most common questions are: How long does it take to charge? What’s the range? Do you have to pay for the charging? How long will the battery last before it needs replacing?) It’s great to spend some time answering these questions but a good pro tip is to ask the person to wait twenty seconds while you plug your car in and ensure it is charging. (Look for the Tesla “T” logo in your charge port and wait for it to begin flashing green as this indicates that the car is charging.) That way your car can be filling up with electrons while you talk, rather than finding yourself engrossed in the conversation only to realise you could have been charging for the last twenty minutes.

  • Always Bring Cables

As already mentioned, your Tesla will may with an included Universal Mobile Connector (UMC). If it didn’t you can purchase one here. If you’re using the UMC as the means of charging your Tesla at home, it can be inconvenient to wrap it up and take it with you each time and it’s easy to forget too, therefore, Tesla and TOCWA recommend the Tesla Wall Connector (HPWC) but there are also other options. With a Wall Connector at home, you’ll be able to always keep the UMC in one of the three convenient storage spaces of your car, either under the bonnet in the ‘frunk’ or in the well under your main boot or in the boot itself. Should you find yourself in a situation where you need to charge you’ll have a cable ready to plug into any 10A or 15A power socket or a 32A 3-phase outlet if you bought the additional adaptor pig tail. For a faster and more convenient charge, there are an increasing amount of Type 2 (a.k.a. Mennekes) AC chargers at shopping centres, fast food outlets and other locations and many of these are untethered requiring a BYO Type 2 cable. You may also choose to carry a 10A or 15A extensions cable.

  • Always Browse Comments

As already mentioned, the Plugshare app should be considered a must for any EV owner. One of its numerous handy features is to see if a charger is being used before planning to charge there, but It’s also a good idea to take note of the last successful charge and to read any comments that the person may have written. If the last charge was unsuccessful it may be an indication that the charger is faulty, damaged or offline. It may also pay to check the opening hours of the charger as some may be located behind gates that may be locked outside of opening hours. Some chargers such as those located at car dealerships may be reserved for the dealership during opening hours and kindly made available to the public afterhours. Using these chargers outside the public times may result in the owner making the charger unavailable to the public.

  • Adjust Battery Consumption

As already mentioned, it is almost unheard of or at least very rare for a Tesla run out of charge, however, should you find yourself in this situation, if you haven’t done so already, ensure you have set your destination in the car’s navigation system and follow any of the car’s warnings.

Another very good option may be to reduce your speed. You’ll be amazed just how much of a difference a drop in speed of 10km per hour can make. As a rough rule of thumb, dropping your speed by 10% from say 110km to 100km per hour could reduce your consumption and hence increase your range by about 14%.

You could also try to use the air-conditioning system or the fan instead of open windows or to use seat warmers rather than the heater in winter.

You may also consider increasing the pressure in your tires by pumping them up to say 45 PSI but only do so if it’s safe and always ensure you keep your tires below the maximum recommended limit.

Always have 3 charging plans A, B and C

[2024 update: With WA now having eight and soon nine Tesla Superchargers which boast a 99.95% uptime and with the WA EV Network almost complete and the NRMA Network to hopefully soon begin to offer redundancy chargers, this rule is becoming less important, however, with more EVs than ever on our roads this rule is definitely worthwhile adhering to especially on longer road trips during holiday and other busy periods.] In short, always have a plan B and a plan C charging plan at the ready in case a charger is either down, ICEd or occupied.

Public Charging Etiquette

Last but certainly not least, a few things about public charging etiquette. It’s important to realise that an EV charging bay is exactly that. It shouldn’t be confused with a parking bay. Think how you would feel to arrive at a charger with a low state of charge in desperate need of a top up only to realise the charger is being taken up for hours by an inconsiderate EV owner who may have reached a full charge some time ago or worse still who hasn’t needed or bothered to even plug in. To combat the problem, Tesla Superchargers are now charging idle fees at a rate of $1 per minute, particularly when half or more of the stalls are being used, so treating a public charger as a parking bay may prove expensive.

IF 50% or more of the stalls at Tesla Superchargers are being used your car will automatically drop the charging limit to 80%. This is to ensure the chargers are available as the last 20% can take the longest.

As the table below illustrates, the fastest charging rates can be achieved between approximately 10% and 65% state-of-charge but for more tips on the best and most efficient way to charge at a fast DC charger or a Tesla Supercharger, please see this article: 100% a Waste of Time: Why charging to 100% is defeating the purpose of Superchargers

 It may also be helpful to log into the Plugshare app to register your charging session so that others intending to charge at that location can plan their journey accordingly. Logging your charging session into Plugshare is by no means compulsory, especially at busy metropolitan chargers but it may be particularly helpful and considerate to other EV drivers at remote locations or in regional areas. Another useful alternative may be the Need to Charge service.

It’s also important to realise that there is no such thing as a ‘free’ charger, there are only complimentary chargers. This is an important distinction, because many businesses who have agreed to host EV chargers, (some after numerous pleas by EV enthusiasts), have done so in good faith for little if any monetary reward. If a business, agrees to host, service, maintain and cover the electricity consumption costs, not to mention the capital costs associated with procuring, purchasing and/or installing and commissioning the EV charger, the least we can do is to buy something at the business. It also goes a long way to explicitly thank the establishment for installing and hosting the charger and it doesn’t hurt to leave a tip either. There are also some chargers such as the Biofil units running on used chip oil which require the manual starting of a generator, such as those put in with the help of Jon Edwards and the crowdfunding from the WA EV community at the Caltex service station in Jurien Bay or the Roadhouse in Caiguna. It may be worthwhile giving the business a call beforehand to let them know of your expected arrival time. Unless there are other EVs waiting for a turn, once charging, it’s advisable to charge for at least 20 minutes or so before the attendant has to return and turn off and pack up the charger. If you can’t charge for at least 15 minutes or so, please offer to pay for a full charging session as it can be annoying for the attendant to have to leave paying customers to come out to turn the generator on for you only to have to come back a couple of minutes later to turn it off to recoup a couple of measly dollars. [2023 Update: For exactly the reason explained above, these chargers now have a minimum $50 charge cost.]

Lastly, a tip for new owners. If you’ve noticed your car only has a single reversing light, don’t worry there’s nothing wrong, the car only comes with one white reversing light on the left as the right one is a fog light. Hopefully this will save you a phone call to Tesla as they get a few of these every day. Update: Soon after this article was published Tesla began shipping Model 3s with two reversing lights. Therefore, there will now be some models delivered around the end of February or early March 2022 with a single reversing light but the later models will have two reversing lamps as well as bigger indicators. (By the way, some very early Model S cars also came with just one reversing light.) 

For further information please see: https://www.tesla.com/en_AU/support/after-taking-delivery and if you get stuck you can reach out by calling the TOCWA helpline on 6262 3131.

Pete Petrovsky

Pete Petrovsky is an active TOCWA (Tesla Owners Club of Western Australia) committee member and a long-time EV enthusiast. He placed a $6,000 deposit for a Model X (#39) in 2014 but when it came to taking delivery he couldn’t justify the cost, so instead, he and his wife decided to buy two PHEVs and wait for the Model 3. In March of 2016 they bought the Holden Volt and a couple of weeks later the Mitsubishi Outlander PHEV, and on the day it was unveiled, Pete ordered the Model 3. After selling the Outlander, in September 2019, Pete took delivery of the Model 3 and despite still loving their Volt, Pete and his wife are now looking forward to ordering the Model Y as soon as it becomes available in Australia.

When he gets time, Pete posts videos on his ‘Tesla Ahead of the Curve’ YouTube channel. He is a long-term Tesla shareholder and over the last eleven years has been responsible for more commercial rooftop solar PV in Perth than any other individual. In 2016 Pete added grid electricity to his role and since October 2020 he has been Managing Director of Imppact Energy Consultancy. In July of 2011, Pete also installed one of the first ‘oversized’ 6KW solar PV systems in Perth, which to this day continues to power their home and both EVs with free sustainable energy.

Glass in Cars

Written by Nigel Farrier

There has been a lot of discussion going around about how the glass roofs on cars cause the car to get too hot making the air conditioning useless. Also people wonder about getting sunburnt through the glass roof.

As a (retired) medical practitioner as a skin cancer specialist and a scientist I can answer all these questions and more.

1 Ultraviolet light.

Lets first discuss UV radiation. There are basically 3 types of UV – UVA, UVB and UVC. The latter is the most damaging of all. UV light is one the electromagnetic spectrum with shorter wavelengths than visible light. UVA is the closest to visible light.

Fortunately UVC, whilst being the most damaging, is completely absorbed by the atmosphere so none ever reaches our skin. UVB is the middle group and is the one that causes sunburn. UVA has the longer wavelength and is assocaited with skin aging.

So what about glass? Remember that not all glass is equal so this is a generalisation. Glass is designed to let light through so UVA, being closest to the visible spectrum, can penetrate glass but only about 60% actually gets through. Fortunately UVB is totally absorbed by glass.

Glass fitted to the front windscreen of cars lets through UVA as above. A lot of side windows are slightly tinted in modern cars so a much larger proportion of the UVA is absorbed. Roof glass, certainly on the Teslas, is coated with a variety of filters that blocks most of the UV light. According to Tesla the roof absorbs at least 99% of all UV radiation. So it will not cause sunburn and little to no skin aging. You would have to sit in your car in bright sunshine constantly for at least 100 days to get the same UV dose as standing out in the sun for 1 day. Quite insignificant.

2 Infrared light.

At the other end of the visible spectrum is red and beyond that infrared and just as UV is divided into 3 bands so is infrared. Unfortunately is is not named as easily as UV but near, middle and far infrared. Near IR is the closest to visible red.

So does IR get through glass? Well once agin the answer is that depends. IR is a form of light, not heat. The heat is transferred by molecules vibrating.

So as before the near IR wavelengths are let through by glass as they are closest to the visible bands. The energy from near IR is too large to excite atoms in molecules from vibrating.

The middle band of IR is often referred to as thermal IR. This band will cause molecules to vibrate and ‘heat’ up (actually generate heat). This radiation is strongly absorbed by matter (glass in this case) so does not get through. But it will heat up the glass. Far IR is the same although has a lower energy state.

The glass on Tesla motor vehicle roofs has several coatings to absorb a lot of this energy before it enters the cabin. As already stated virtually no UV gets into the cabin and the IR is absorbed by the coatings and the glass in the roof. This does cause it to heat up which can then radiate that heat into the cabin (and out into the atmosphere as well).

As an interesting experiment try using an infrared camera to look at items through a glass window. You wont get a very clear picture at all even with the IR LEDs that a lot of security cameras have.

So there we have it. Certainly do not panic about the UV radiation through the glass roof. With regard to the infrared yes it will slowly heat up the glass and then the interior of the car. So does a metal roof. It heats up in the sun and radiates the heat into the car and the car heats up.

So what can we do to prevent this? Most people rush out and buy shades for the roof, put on tinting and so on. Lets cover these ‘solutions’.

Window tinting – from an aesthetic point of view a lot of people really like tinted windows and I can understand that. But it does not make much difference to the IR heating up the windows which then gets radiated into the cabin. It also make ZERO difference to the amount of UV getting in in modern cars. If you want window tinting that’s fine. Do it.

Roof tinting – there was some problems in the early days of putting the tinting on the inside of the roof causing the roof glass to crack. That may have been solved now but personally I am still hesitant about putting tinting on the inside. The glass roof still gets hot.

There is a ceramic coating that can reflect some of the IR light and this is put on the outside and probably helps a bit but it needs to be replaced after some years.

The Tesla glass roof already has at least 3 layers of coating on it to prevent a lot of the problems (hence the problem that some people think the roof is rusting due to an orange hue it got).

Inside roof shades – these are similar to the windscreen shades that a lot of people use. They still dont stop the roof glass from getting hot and several makes actually impede the view from the rear windscreen as they hang down at the back.

What is the answer then? Here are my tips for an enjoyable experience in your Tesla.

Firstly leave the air conditioning on when you leave the car in the sun. You have almost certainly used it whilst driving to where ever you needed to go so it has already done its job of cooling down the interior. For it to keep the interior at that temperature it will use less energy to maintain it than it does to get it down to that temperature.

This is a really great idea if you are parked up at a charger and plugged in as the power from the charger is used to keep the car cool rather than the battery pack providing you are not plugged in to a 10amp socket as the air conditioning may need more power than that can provide so some battery use may happen.

If you are leaving your vehicle parked always try and put it in the shade with or without leaving the air conditioning running,

If you are leaving your vehicle parked for quite a while (and its in the shade) you can leave the air conditioning set to keep the cabin below about 40 degrees C using the cabin overheat protection mode.

Still dont want to do any of this? Why not just turn on the air conditioning from your Tesla app on your phone giving it enough time to cool the cabin for your arrival?

None of these will work once the battery state of charge falls to below 20% (neither will sentry mode).

Whilst on this subject of air conditioning I would also like to cover some of the misunderstandings regarding what is in a Tesla. I must admit for the first few months of ownership I was convinced the air con was not very good until I found out a few things (such as leave it running).

During the hot weather I have mine set at about 22.5 deg C and on AUTO (experiment to find your own preferred settings). It works fine. You wont feel a blast of cold air on your face as in other vehicles as they have small outlets that can be directed at your face. Teslas don’t do that. You can direct the vents towards you but you wont feel it and this is why a lot of people say the air con is useless. Its not. The cabin gets down to its temperature very efficiently and the fan (when on auto) slows down.

I leave mine set to auto and let the car take care of the interior itself. You have just been used to something different and therefore feel its not as good. It is.

In summary then. You wont get sunburnt from the UV. The roof glass will get hot so don’t keep touching it. Try touching the metal roof of any car that is out in the sun. You will burn your hand just the same. Tint the windows if you want to for aesthetic reasons (and it may decrease slightly the UVA getting in through the side windows). Before you go out and spend a lot of money of roof tinting, shades etc before you have taken delivery (I know several people that do this) just try it out first.

I sit with my completely bald head only 2 inches from the roof and even in the 40 degree heat we get here I do not feel the need for anything except my cars air con.

Explaining the Nullarbor EV Chargers

As you may have seen in recent news retired engineer Jon Edwards has designed, built and installed a Biofil DC charger at Caiguna on the Western side of the 1200km drive between Ceduna and Norseman, this provides a handy boost for the adventurous EV owners crossing the Nullarbor when border openings allow. Before I continue let’s make one thing very clear, you’re under no obligation to drive across the Nullarbor, commercial air travel is faster, safer and probably cheaper, but as Ferris said “Life moves pretty fast, if you don’t stop and look around once in a while you could miss it”.

Below I’ll discuss the charging available at the locations that are spaced evenly apart.

Before attempting to drive an EV across this part of Australia remember that Plugshare is the only app with the accuracy to plan charging stops, also don’t rely on apps to predict your energy consumption and arrival times, the road surface and wind direction plays a major part in how far you’ll get on a charge, play it safe and always plan to arrive with at least 30kms of range remaining. If you wisely plan your daytime and overnight charging stops the less time you’ll spend topping up the batteries.

Balladonia 22kw CCS2 DC charger

Departing Norseman and driving East the first well spaced charging stop is at the Balladonia Roadhouse, 190kms from Norseman, which has a 22kw CCS2 DC charger plugged into the 32amp 3 phase outlet. Compared to the latest 250-350kw DC chargers popping up close to Australia’s populated areas 22kw appears prehistoric, but in reality they’re a pretty handy short term solution that doubles the charging speed a model 3 can get from the existing 3 phase outlet and better still triple the charging speed available to a Hyundai Kona.

Caiguna, 181kms drive from Balladonia, has a 50kw DC charger powered by a Biofil generator, politely ask the counter staff to start the charger then go and enjoy the air conditioned Cafe.

Madura 22kw CCS2 DC charger

Madura, 157kms drive from Caiguna, has a 22kw DC charger plugged into the 32amp 3 phase outlet, payment is a donation to the Royal Flying Doctor Service tin located in the dining area. Note: as at April 2024 not available due to plug issue.

Mundrabilla, 116kms from Madura and 81kms from Border Villa, now has a 22kw CCS2 DC charger plugged into the 32amp 3 phase outlet. Note: as at April 2024 3 phase only available.

Eucla, this location is 182kms east of Madura, charging is via a 32amp 3 phase outlet in the Laundry of the Eucla Motor Hotel. Be aware that this outlet is not available between 9.00am and 3.00pm, if you expect to arrive at this time maybe use the Border Village charge point, 12kms to the East. Note: this location is no longer available for EV charging.

Nullarbor Roadhouse 32amp 3 phase

Nullarbor Roadhouse, 197kms drive from Eucla, has a 22kw CCS2 DC charger plugged into the 32amp 3 phase outlet at the rear of the building close to the motel units. Note: April 2024 NRMA DC charger now in place.

Penong Caravan Park, 223kms east of the Nullarbor Roadhouse, has a 32amp 3 phase (it has been prone to tripping at 28amps so plan accordingly). Penong is part of the South Australian grid so is likely to get a reasonable speed DC charger before too long.

Cocklebiddy and Border Village also have handy 32amp 3 phase outlets if you want to shorten the driving distances between charge sessions or wish to try different accommodation on the return journey.

Tesla Model 3 Economics Compared to an Average Australian Petrol Car

Pete Petrovsky 26 Nov 2021

One of the comments that gets the most eyebrow-raising reactions when talking about Tesla cars, is the fact that, for most owners, a Model 3 works out considerably cheaper than an average Australian car. Although some people are beginning to understand that an electric vehicle (EV) is less expensive to run than an internal combustion engine (ICE) vehicle equivalent, it’s hard to come across a non-EV owner who isn’t surprised to learn that, if all major costs associated with owning a car are included, a Model 3 Rear Wheel Drive (formerly known as the Standard Range Plus) works out thousands of dollars cheaper over just a short three-year period of ownership.

I like to explain this with a second-person hypothetical. Let’s assume that you decide to buy a Model 3 Rear Wheel Drive (RWD) today and your neighbour also buys a vehicle on the same day, but instead they choose an average Australian car, something along the lines of an average Ford, Toyota, Volkswagen, Nissan, Subaru, Honda or similar. The longer the ownership period the more favourable the outcome for the Model 3, and even thought the average Australian car is more than 10 and a half years old, let’s assume that both you and your neighbour sell your cars after just three years. If we take into account all significant costs, including the upfront drive away cost, a.k.a. the sticker price, and if we include depreciation, fuel costs, maintenance, insurance as well as registration and licencing fees, after all is said and done, you will be left with almost $14,000 more in your bank account than your neighbour who bought the average Australian petrol or diesel car. That’s a substantial amount of money, it’s enough to buy a second new car. Many people are either astounded by this or they simply don’t believe the figures. I have therefore provided a summary table of my calculations, below.

Tesla Model 3 RWD versus average ICE car total cost of ownership table

As with all calculations, the devil is often in the detail and assumptions can make or break even the most robust models. Where possible, I have therefore, tried to only use robust figures from reputable sources which I can readily substantiate. For example, as the Model 3 has only been in Australia for a little over two years and with the current resale values being elevated by unique market dynamics stemming from the Covid-19 pandemic, I have based the depreciation rates on the iSeeCars.com study which analysed 5.7 million new cars bought in the united states between January and June of 2017 and 1.2 million cars from the same model year sold between January and June in 2020. I have tested the model to the sensitivity of the inputs and, interestingly, even if we were to halve the depreciation rate used for the Model 3, while keeping the depreciation rate for the average ICE car unchanged, the Tesla would still come out more than $7,000 ahead.

I have also used Australian unleaded petrol prices averaged over a 10-year period from 2011 to 2020 inclusive, however, rather than using average Australian electricity prices for the same period, I have simply used the latest (and also the highest) average Australian tariffs even though, as most electric vehicle owners know, there are several EV friendly tariff plans available to EV owners. Furthermore, as is the case with many EV owners, the cars can be charged using electricity produced by solar photovoltaic (PV) systems. Once the solar PV system has paid for itself, it can effectively provide free electricity for its owners who mostly either charge at home or at convenient destination chargers such as those located in shopping centres which are generally complimentary. It is, therefore, not impossible to fuel an EV at virtually zero cost.

For the servicing and maintenance costs, I have used prices sourced directly from Tesla, but I have used average logbook service costs which include capped-price service schemes as well as prices taken from lower-cost third-party service centres. For more information, please see the video below which reveals that the Model 3 costs about a third as much to service over a 5-year period than the cost of a single service for an average Australian car. In other words, it costs less to service the Model 3 over a three-year period than an average Australian internal combustion engine (ICE) car over six months.

Although, I have been conservative with the inputs in the calculations, with the Model 3 RWD (nee SR+) starting at a drive-away price of $63,626 as an average across all the states in Australia, versus approximately $40,912 for an average new Australian car, one could argue the analysis ignores the additional finance costs. As the table below shows, however, even after factoring in finance costs, the Model 3 still comes in $12,617 ahead of an average Australian internal combustion engine car.

Total cost of ownership comparison table

Whether it’s $12,617 or $13,679, either way, it is a relatively large sum of money, as I have mentioned, it’s enough to pay for a second new car, but amazingly this is not where the savings stop. You may have noticed, there is one category, namely insurance, where the Model 3 is more expensive. That said, while insuring a Tesla may be more expensive in absolute terms, mainly due to the higher car value, personally, I have found the premiums cheaper relative to the insured value of the vehicle and the Australian average figures seem to be roughly on par in this respect with the annual premiums accounting for between 3–4% of both of the cars’ drive-away price.

Interestingly, however, this is one of the areas where Tesla continues to innovate. Two years ago, Tesla introduced its own insurance product in California, named Tesla Insurance. As Tesla begins to slowly roll out the product across other US states, the company is pairing the policies with its Safety Score telematics which, as the name suggests, provide the driver with a safety score based on their driving behaviour which is designed to statistically predict the likelihood of a future collision. Tesla bases the monthly insurance premiums on each driver’s Safety Score, and as the score changes the insurance premiums also change from month to month. Tesla calls this Real-Time Insurance. Naturally, the higher the safety score the lower the premiums. For example, there can be more than a 56% premium discount based on a 98% versus an 88% Safety Score. It remains to be seen when Tesla introduces the Safety Score to Australia or when Tesla enters the Australian car insurance market but when it does it will make the economics of the Model 3 even more compelling not only for new owners but also for existing ones.

The only other area where a Tesla Model 3 is more expensive than an average internal combustion engine or ICE car is the upfront cost or the sticker price. This is where state and federal governments should play their part, it’s crazy that we’re still subsidising fossil fuels while taxing electric vehicles.

Model 3 RWD on-road taxes, fees and chargers by state in Australia

That said, Tesla is working on a US$25,000 model commonly referred to as the ‘Model 2’ but Elon Musk has already confirmed this won’t be the car’s name, perhaps it may end up being named the ‘Model A’. Once it is unveiled and when it eventually goes on sale in Australia, it may retail below or roughly at around the price of an average petrol or diesel car thereby not only putting the economics of an entry-level Tesla even further beyond any question, but it will inevitably become the final death blow to the internal combustion engine as a means of powering a daily commuter.

It is fairly amazing that the Model 3 has economics which are superior to an average Australian car because implicit is the assumption that the two are a like-for-like comparison when, in reality, nothing could be further from the truth.

The fact is that a Tesla Model 3 is superior to an average internal combustion engine vehicle in pretty much all aspects including:

Furthermore, unlike most cars which are the best they will ever be the day they are driven off the dealership lot, the Model 3 continually improves via mostly free over-the-air (OTA) software updates.

The impressive yet not exhaustive list below outlines just some of the additional features which have been added to my Model 3 since I bought it a little over two years ago:

  • a boost of approximately 5km more range,
  • approximately 5% more power,
  • single pedal driving,
  • dog mode,
  • camp mode,
  • side camera video feeds,
  • Netflix,
  • YouTube,
  • a long list of new voice commands including voice keyboard,
  • ability to have incoming SMS messages read out and the ability to dictate a response,
  • driving visualisation updates including displaying humans, stop signs, traffic lights and even objects such as traffic cones or witches hats, rubbish bins, traffic barriers and so on,
  • automatically save dashcam footage on honk,
  • ‘Caraoke’ and a raft of new video games,
  • driver profiles,
  • ability to adjust the charging rate via the app,
  • app customisation,
  • car-wash mode,
  • Smart Summon which enables the car to drive itself from up to 50–60 metres away in a car park,
  • and a raft of driver assistance and Autopilot improvements such as the ability to monitor the speed of traffic in surrounding lanes and, if required, overtake other cars. The car can also stop on traffic lights, stop signs, roundabouts and so on.

These are just some of the additional features added over the last 2 years, but it doesn’t stop there, as innovation and improvement seem to be a continual ongoing process at Tesla. There are many new exciting updates on their way including the Full Self-Driving (FSD) capability beta button, the Safety Score beta, the FSD subscription service, the ability to detect wet road conditions, remote live sentry view, in-car purchases and these are just some of the upcoming features we currently know about. I’m sure there are dozens of more improvements in the pipeline which we are yet to find out about.

Furthermore, this is just what I either happened to notice or read about in the software release notes, but the car has also been improving its already unmatched safety with undocumented updates like safer airbag deployments adjusting for occupants’ weight and seating position. In other words, the airbags now adjust when, how fast and in what direction they deploy depending on where on the seat the driver is sitting. The algorithm also considers the pressure distribution on the car seat to determine if the passenger is a baby, a toddler or an adult and it even tries to calculate the probability of a person’s gender.

In addition to the over-the-air updates, the cars are equipped with all the hardware necessary to enable full self-driving (FSD) in the not-too-distant future. One could argue that this makes the cars themselves but perhaps also the economics largely future proof. Perhaps this and the potential that FSD may one day be worth US$100,000 is an important factor contributing to the Model 3 showing a depreciation rate that is 25% lower than an average car.

Does this mean that a Model 3 or a Tesla for that matter is the right EV or even the right car for everyone and for every situation? No, of course not, but taking into account FSD improvements, in the majority of situations, the Model 3 and Model Y superiority, not only in economic terms but also in terms of both the quantitative and the qualitative value they offer their owners, makes one wonder if we haven’t already reached the point which Elon Musk referred to when he compared driving anything other than a Tesla to owning a horse or as he further elaborated, it is “financially insane to buy anything other than a Tesla”.

He placed a $6,000 deposit for a Model X (#39) in 2014 but when it came to taking delivery he couldn’t justify the cost, so instead, he and his wife decided to buy two PHEVs and wait for the Model 3. In March of 2016 they bought the Holden Volt and a couple of weeks later the Mitsubishi Outlander PHEV, and on the day it was unveiled, Pete ordered the Model 3. After selling the Outlander, in September 2019, Pete took delivery of the Model 3 and despite still loving their Volt, Pete and his wife are now looking forward to ordering the Model Y as soon as it becomes available in Australia.

When he gets time, Pete posts videos on his ‘Tesla Ahead of the Curve’ YouTube channel.

100% a Waste of Time: Why charging to 100% is defeating the purpose of Superchargers

Pete Petrovsky 21/10/2021

Supercharging Karrinyup

As most EV owners will know, there are two main ways to charge an EV, AC or DC, but there’s also another less known and slightly more nuanced distinction.

A charger’s main purpose can be for rapid top ups or for longer perhaps even overnight charging and it’s important for EV drivers to understand this difference as it will not only save a lot of time, but it will also result in a better ownership experience for the entire EV community.

The main purpose of ultra-rapid DC chargers such as the Tesla Superchargers is rapid top-ups to facilitate convenient travel between built-up areas. This is critical in winning over the broader driving public who have concerns about charging downtime on long trips away from home. The problem is many new owners have misunderstood this and are in fact wasting a lot of their time charging at high battery percentages. How much time are they wasting? It depends on the vehicle’s next destination but as can be seen from the graphics below, it’s more than many drivers realise.

Test conducted with a Tesla Model 3 Performance charging from a V3 Tesla Supercharger at a 14-degree outside temperature with a pre-conditioned battery.

As the chart above shows, a long-range battery takes about the same time, roughly 14 minutes, to charge from 10% to 60% as it does to charge from 90 to 100%. In other words, you can spend the same 14 minutes topping up 50% at a lower state of charge (SoC) or 10% at a higher SoC. 

50-60% SoC is a key level because not only does the time to charge each 5% increment begin to lengthen to charging speeds attainable at slower (non-ultra-rapid) DC chargers but generally it’s enough battery capacity to cover the distance between Superchargers on long road trips.

What is not illustrated on the graph is what happens once the state of charge reaches 100%. Once at 100%, the charge time jumps off the chart as it took me at least a further 19 minutes of trickle charging the last few watt hours and balancing the cells before I lost patience and quit the test.

TezLab power chart.

As can be seen in the graphic above, at roughly around a 14% state of charge (SoC) the car reached its peak charge of 244kW but then this began to taper off down to 192kW at 30% SoC, then to 110kW at 50%, 81kW at 70% and 42kW at 90% before dwindling down to 5kW once it remained at 100% for almost 20 minutes.

Once at 100%, the time the car takes to completely finish charging is dependent on how long it has been since the battery was fully charged to 100%. The longer the period between full charges the longer it takes to balance the cell groups and the longer the battery takes its time at the 100% level.

Powered by a lithium-nickel-cobalt-aluminium (NCA) battery chemistry, once at 90% or above, it is best to begin driving the Model 3 Performance (and Long Range) to ensure minimum long-term battery degradation. It’s not ideal to keep this chemistry above 90% or below 20% for extended periods of time. In fact, the above 90% charge level should be reserved only for times, when necessary, on longer stretches between chargers on country road trips. However, that said, it is also a good idea to balance the cells once every 3-6 months. The added benefit is that the battery management system (BMS) will also get a chance to recalibrate itself to ensure accurate battery range readings.

In contrast, it is ideal to charge the lithium-iron-phosphate (LFP) battery chemistries, found in the Shanghai built and soon also in the Fremont built Standard Range Plus Model 3s, to 100% at least once a week and it’s also perfectly fine to charge to 100% on a daily basis.

Irrespective of the battery chemistry, however, to save wasting your time at Superchargers and unnecessarily taking up this important infrastructure, please be mindful of how busy the charger is. If you feel the need to charge to 100% and if you have plenty of time, during off-peak times when Superchargers are hardly used, it is perfectly fine to squeeze in every last watt but at busy times, vehicles taking up much needed charge bays while charging at a fifth or less of the charger’s potential is a burden on the infrastructure and not helpful to fellow EV owners.

243kW charge rate.

Therefore, please consider only charging to a lower percentage and leaving the charging at the top state of charge levels for your home, BNB, or at overnight AC destination chargers such as those allocated to your room at hotels and EV-friendly resorts. You’ll only be doing yourself, your EV community and even potential new EV owners a big favour.

P.S. Special thanks to TOCWA Chairman Rob Dean for not only helping with this article but also for coming up with the idea for the test.

Jurien Bay DC charger critical instructions

Due to a redevelopment of the Jurien Bay foreshore the “plan B” 3 phase outlet has been removed making the 50kw DC charger at Caltex even more important for those looking for a short stop on the trip between Perth and Geraldton. There is a Tesla destination charger at the tourist park but this is limited to 3.6kw so is only useful for an overnight stop.

If Perth to Geraldton is only 410kms via the coastal road do I need to stop? In most cases, absolutely yes, due to the nature of the road surface and almost constant winds it’s near impossible to achieve reasonable energy efficiency, driving at slower speeds on this busy road and being a road hazard is not an option so it’s best to accept the inevitable and plan a 25 to 40 minute stop at Jurien Caltex while adding 20-40% back to the battery. 

The most critical aspects to using the Jurien Bay DC charger is to carefully read the operating instructions on Plugshare before arrival, patience is front and centre at this location, if you try and rush the process or miss a step you’ll just waste time. The Tritium DC charger is very reliable, the only time it’s failed to work is due to an issue with a handful of pre 2020 model X or S cars with a CCS2 upgrade or the operator rushing the start up process. If your Tesla is less than 24 months old, you should not have any issues with this charger.

A few tips:

Phone ahead your arrival time, Wade or Jarryd will make an effort to be on site as they know the process better than other staff members.

Make sure when the charger is unlocked both charging handles are firmly pushed into the holsters before and while the charger completes its 5 minute start up process.

Don’t arrive at this charger with less than 50kms of range, even though it’s so far been extremely reliable there is no longer a plan B in town, keep enough spare range to drive the 24kms to the Cervantes destination charger.

Don’t complain about the price, the $50 flat fee may appear high (it used to be 70 cents per kWh and a $25 minimum) but the Electric vehicle owner that spent tens of thousands of dollars installing the Jurien Bay unit will never see a return on investment.

Planning a long distance trip away from DC chargers

If you’re keen to drive you’re Tesla north of Geraldton or east past Merredin it can be done safely as long as you have patience and prepare correctly. If you treat the journey as an adventure you’ll enjoy the trip, treat it as a task that needs to be completed ASAP and you’ll wish you stayed at home.

What will you need to carry?

You don’t need a large variety of charging cables but you do need charging plans A, B and C.

  • Plan A is the Tesla destination chargers located around the state, so far most of these have been reliable and most also have a 5 pin three phase outlet nearby as a backup.
  • Plan B is a 3 phase mobile connector such as a juice booster or KHONS charging cable that plugs into the dozens of 3 phase 5 pin outlets located all over Western Australia, this will generally provide the same charging speed as a Tesla 3 phase destination charger. Unless you’re planning many long distance trips I suggest you borrow a KHONS cable from TOCWA, paying over $800 for a cable you may only use a handful of times is not good value.
  • Plan C is the UMC that is delivered with the car, it’s the one in the square black bag. You may never use this cable but you must carry it, if everything else fails this will get you home, slowly but eventually.

North of Geraldton and east of Kalgoorlie you’ll need a spare tyre, jack and associated equipment. Puncture repair kits are a handy plan B but won’t get you out of trouble if the tyre damage is severe, besides you don’t want to be hanging around some outback town for 3 days while a spare tyre gets transported in. Keep in mind the best way to reduce tyre issues on a long trip is depart home with plenty of tread depth. A spare tyre and wheel combo is available to loan from TOCWA.

The Plugshare app is critical, make sure all fields are open so you don’t miss any charging options. Before departing to the next charging location it’s important you read not just the  location details but also previous comments, this may well save you a lot of time and frustration on arrival. Don’t forget to log in and if necessary leave a tip for the following drivers, it’s a great way to support the EV community.

Charging tips.

At some stage in the future virtually all locations in Western Australia will have fast DC charging until then the following tips will make any trip far easier.

  • Charging from AC will provide the same power transfer and charging speed no matter the battery state of charge right up to approximately 97% so there’s no time saving in adding the bare minimum charge to get to the next location, this is where the saying “Always Be Charging” comes in, take the charge where its available, the next charge location may only be 200kms along the highway but if it doesn’t work you could be spending the next 15 hours charging from a caravan park socket rather than the lunchtime stop you expected. Arriving with 40% state of charge is far wiser than arriving with less than 10%.
  • Don’t try and charge too fast if you don’t need to, especially overnight on three phase. If the Plugshare comments say the breaker trips off with extended high amp charging go to the touchscreen settings and drop the amps down a small amount so the car completes charging just before you plan to depart, slower charging is better than no charging.
  • Cool the car interior just before departure while still charging, this reduces the energy consumption from the battery needed to cool the car down once back on the highway.
  • Ask permission to charge before you plug in. Many of the charge locations in regional WA are provided through the good will of the local business, it’s important to return the favour with a friendly chat if possible. Take note that due to staff turnover the person behind the counter may not even know a chargepoint exists, check the exact location by browsing the plugshare photos beforehand.

General tips.

Get an early start each day and get off the road before dark – there’s far less traffic on the road in the early morning and it’s generally cooler. There’s still some wildlife hanging around the side of the road but it’s easier to see without a continual flow of headlights heading towards you. Early starts and early finish also provide some flexibility if your planned journey for the day takes longer than expected.

Don’t get too confident in quality accommodation being easily accessible, if you want the best possible overnight stay, ring well in advance, and make sure you arrange key collection. Many of the regional locations close up the front office by 6.00pm.

A number of TOCWA’s committee and members have completed long distance journeys throughout the state as well as around Australia, they are willing to share their experience with others so don’t be afraid to ask if you want more information.

Avoid switching off the air conditioner to save energy.

I’ve noticed a lot of drivers recently tell how they turn off the air conditioner to gain extra range, this stems from a misunderstanding of how much energy a Tesla HVAC system (Heating, Ventilation and Air Conditioner) consumes under various conditions. It’s only if you’re driving in areas north of Geraldton or east of Merredin that you should be concerned with energy consumption (or if you’re paying insanely high electricity prices). In the city and suburbs crank up the cooling or heating and enjoy that car.

As virtually all country areas in Western Australia that may require some energy conservation are warmer areas, I’ll stick to discussing HVAC cooling.

So why not turn off the HVAC cooling or open the windows?

Driving an aerodynamic vehicle with the windows open above 40-50kmh is a backward step, more energy will be consumed from poor aerodynamics than an air conditioner would normally consume, the faster you drive the bigger the difference.

Driving a long distance in a car with a hot interior is not worth it unless the situation is desperate, besides the safety risk of possibly losing concentration, you’re also reducing the enjoyment of driving a Tesla.

When cooling the amount of energy the HVAC consumes depends on a couple of factors; how low a temperature the HVAC is set too, the interior and outside air temperature and often lastly but often overlooked; how long the car has been sitting in the full sun before switching on the HVAC, a significant part of the heat absorbed by the cars bodywork will transfer through to the interior adding to the task of cooling the inside air.

How to get the best range while still using the HVAC cooling.

  • Try and park the car under shade before departure, this could save 10-15kms of range over a 350km trip.
  • Pre cool the interior whilst the car is still charging, on AC charging this may reduce the charge speed but getting extra distance covered is more important than the few extra minutes it may take.
  • Set the thermostat higher, you may enjoy being spoilt with a 20C interior around the city but 23C over a long drive is better than no cooling at all.
  • Drop 5kmh- If the choice is drive at 100kmh with no HVAC cooling or 95kmh with cooling the 95kmh journey is going to be far more enjoyable, besides driving at 95kmh only makes the 350km trip 11 minutes slower.

Over the long term as DC fast chargers are installed in WA country areas reducing most trips to below 250kms the above advice will no longer be applicable, but in the meantime stay cool and enjoy that car.

Tesla Destination Charger Problem Solving

On occasions you’ll plug into a destination charger that doesn’t appear to work, a small number of these public chargers are becoming unreliable mostly due to the cable getting mistreated, to add some confusion the same charger will not work for one car and then work first time for the following car on the same day, the Williams Woolshed destination charger is a great example.

To make the Tesla experience a bit easier here are the steps to work through that will hopefully get a Tesla destination unit to charge:

If there’s no Green or Red light strip light on the front check that power is switched on at the meter box, some premises keep it switched off for various reason, this will be often noted on the Plugshare app.

If you’ve established that the unit is powered up but a Red light is showing check that the cable is not twisted or stretched in any form, also check the cable is not pulled out from the bottom of the charging unit, that is you can see each individual colored cable rather than the black insulation.

Once the above steps are done locate the Red reset button on the side of the unit, using your thumb press it in and hold until all lights go off and wait until the Red/Orange light on the front turns Green, this will take between 5 and 30 seconds, if all goes to plan the Green light will start moving and the car will charge. If it doesn’t work the first time give it another go, also try unplugging and plugging back in before attempting a third reset, once again make sure the cable is not unduly stressed. If the charging doesn’t start after 4 resets the chances of it working at all on your car are very low.

If you do get charging started don’t rush off, hang around for a minute until the cars charging at full amps, if the unit has a fault it is likely to trip off within the first minute, if it does trip off it’s best to no longer attempt charging and report the issue. If you have no other choice and desperately need to charge try dropping the amps down via the cars touchscreen, keep in mind this is an absolute last resort. As an extra precaution if you walk away from the car to visit the shops or cafe check the phone app after 15 minutes, it’s very likely charging is still okay but there’s no harm making sure.

So, you want to drive to Esperance?

Now that the Lake Grace DC charger is installed and operational the Perth to Esperance drive has become so much easier. I’ve completed the 700km trip in a Model S three times since early 2017 using the slow but reliable 3 phase AC charging. Update July 2024: Please note that with the installation of the WA EV Network there are now alternate DC charging options via Jerramungup and Kojonup.

To make the journey as trouble free and relaxing as possible read on:

  • Perth to Esperance is 700kms via Williams and Ravensthorpe, the Perth to Lake Grace leg is 326kms, Lake Grace to Esperance 374kms.
  • On average you will lose 20 minutes of daylight driving East towards Esperance but gain an average 20 minutes on the return journey West, driving at dusk between Ravensthorpe and Esperance is not recommended so please take the above into consideration.
  • The Albany highway section of 168kms between Perth and Williams can get fairly busy, driving below 100kmh is not recommended or you’ll be very unpopular with the business people who use this road on a daily basis.
  • The Williams to Lake Grace section is flat and fairly good for range, take note if you’re driving into an easterly and factor that into the remaining range.
  • The 186km section between Lake Grace and Ravensthorpe is generally a low traffic road that can be driven a bit slower if needed but is not necessary. Be warned that at certain times of the year grain trucks are using this road, give them every opportunity to do their job as quickly and safely as possible.
  • The 188km section between Ravensthorpe and Esperance is not too busy but the traffic moves fast, it’s also a deceptive road, long sections of very good surface with random spots in need of repair from water damage, take note of the shire warning signs, it could very save you from tyre and rim damage.
  • Don’ be rigid in your trip plan, allow extra time for unexpected delays.
  • Spare tyre and jack, CARRY THESE ITEMS, although you are very unlikely to get a flat tyre, not having a spare when you need one will make it a very expensive and time consuming trip, not the type of memories you want while on holiday. Roadside repair kits are a plan C and are no substitute for a spare tyre in regional WA. Contact the TOCWA secretary regarding a loan spare and advice (free to TOWCA members).

When leaving from Perth I highly recommend you depart as early as possible; firstly there’s less traffic to deal with on the outskirts of town; secondly you have time up your sleeve to stop and take some photos; thirdly and most importantly it’s nice to arrive at your final destination, get the car on charge and relax with a drink before sunset.

How early? That’s up to you but sunrise is a great time to be on the road. If you don’t mind getting some driving done before breakfast the Williams Woolshed is a great first stop for a quick coffee or breakfast, just be aware the charging is extremely fast using the Tesla Supercharger, so get your order in quickly.

Lake Grace is an important charging stop and it’s likely that will take 40 to 50 minutes, if you’re a first time visitor it’s easy to use up that time going for a short walk and having some lunch. The DC charger is currently set to stop charging at 95%, this isn’t really an issue as by that stage the charge rate has likely dropped to a level where the Lake Grace DC charger has no advantage over the slower DC charging in Ravensthorpe.

Pro tips

  • Do not bypass working chargers on this route, even if you think you can get to the next one easily. It will not save you time and could very well delay you for a lot longer than you think.
  • There’s a good chance the moment you arrive a local will walk over and start asking about the car, make sure you plug in and confirm your car is charging before having a long conversation. Once again “Always be charging”.
  • Another tip is to carry the Chargefox RFID card as internet connection is often an issue when using the app.

Ravensthorpe is a small but lovely town that is well worth the stop even if you don’t need to charge, there’s an IGA supermarket on the hillside with a Cafe that provides a nice view. The 150 kW WA EV Network DC charger in Ravensthorpe is now online. Unfortunately the caravan park is no longer available for charging due to the entitlement of some EV drivers. They also have some reasonable priced chalets if driving Perth to Esperance in one day is hard yakka. Charge far more than needed at Ravensthorpe so when you get to Esperance you don’t arrive low on charge and then have to worry about plugging in straight away.

Ravensthorpe IGA is a great spot to grab a coffee and check out the view.

Edit: There are now WA EV Network 150 kW fast DC chargers in Esperance.

Esperance is a great place to relax for a few days, there are two locations with Tesla destination chargers (Smith Street Holiday House and Comfort Inn Bay of Isles) plus the horizon power type 2 and RAC Esperance Holiday Park via the Chargefox app (BYO cable). If you are staying for two or more nights, a 10 amp trickle charge is all you need. There’s plenty to do within walking distance including the local museum which has much more to see than just the Skylab wreckage. If you have time to spare a 90km drive east to the Duke of Orleans Bay is worth the effort, as well as the beautiful white sand beaches there’s a gem of a pub in the village of Condingup that back in 2017 served a tasty lunch.

For the return to Perth, if you want to be a bit more adventurous there are two options, via Jerramungup (Tesla HPWC) & Albany or North via Kalgoorlie. If you want alternate recommendations let me know.

Happy Travels, Rob
