Supercharger tips

The most recent Tesla Superchargers in Karrinyup, Williams and Margaret River are V3, the 2017 built Eaton Superchargers are V2. Those who’ve charged at Eaton will have noticed each charging stall has two cables, the second cable is a retrofitted CCS2, that’s the one 99.9% of WA Tesla owners will use. V3 chargers are vastly superior as each stall is capable of delivering up to 250kw depending on the vehicle battery type and size, starting percentage and battery temperature. The V2 stalls at Eaton have a maximum output of 145kw for each pair of stalls (1A&B, 2A&B, 3A&B), meaning if you plug into stall 1B not long after a car has plugged into 1A your initial charging speed will be very slow. The trick is to avoid parking next to another car if possible. The slower charging speeds at Eaton are only a nuisance on busy Saturday mornings on a long weekend. To get the best charging speed set navigate to the Supercharger and the car will automatically preheat the battery pack before arrival, on cool days this makes a significant difference to the starting charge rate. A second tip for the fastest charge rate is to arrive with approximately 10% range and depart with 60-80% depending on the distance to the next chargers. Arriving with only 10% is advice I would never give with any other type of charge point in Australia, the fact is Tesla Superchargers are vastly more reliable than any other DC chargers in this country.

Why not charge to 100%?

Basically 80 to 100% takes longer than charging from 10 to 60%, wasting time defeats the main purpose of a Supercharger. Be aware that when a Supercharger gets busy charging may get limited to 80%, the phone app will provide a notification, if charging past 80% is absolutely necessary it can be overridden. You can read more here: Charging to 100% is a waste of time.

Don’t overstay you visit- Once your car has completed charging you have 5 minutes grace to move the car, failure to do so will result in a backdated per minute surcharge added to your Supercharger account, as the phone app will pre warn you there’s no excuse.

Driving Perth to Shark Bay in a Tesla

Hopefully by late 2023 this article is barely relevant due to Synergy’s installation of fast DC chargers in Jurien Bay, Northampton, Billabong and the Overlander Roadhouse. In the meantime the trip is comfortable if you plan correctly and show some patience.

Perth-Geraldton, 410kms

This section is energy hungry and can catch out first timers. A long range Tesla can normally make this section on one charge, a performance model maybe if conditions are favourable but unfortunately unless you get a howling tail wind and a warm road a standard range Tesla will need to to stop and top up charge at the Lancelin type 2 AC charger or the Jurien Bay 40kw DC charger. There is a Tesla destination charger in Cervantes but at the time of writing that unit was reported as having an issue, check Plugshare before venturing in to Cervantes.

Geraldton

If you’re passing through the far quickest option is the TOCWA DC charger at the West End. No cable is required but you’ll need the Smartcharge app. For those planning to stay overnight there are 3 different Hotel/Motels with Tesla destination chargers.

Geraldton to Denham/Monkey Mia, 432kms

No matter which Tesla you have it is wise to plan a charging stop, Northampton has a Tesla destination charger, toilets, a good bakery, an IGA and a few other close by shops but is only 52kms from Geraldton, more of a handy stop on the return trip.

The best option is the Billabong Homestead that has supported EV charging since early 2016, there’s a Tesla destination charger next to the self contained rooms (transportables) and a 32amp 3 phase outlet in the caravan park for those that wish to camp. To get safely through to Monkey Mia 1 to 2 hours of charging is required at this location, the good news is the sit down food is fairly good, it has a bar and there’s satellite TV.

Play safe at Billabong and add more charge than the car calculates, when you turn west towards Shark Bay a strong sea breeze can eat into the remaining range very fast and give you a nervous last 100kms.

Denham/Monkey Mia

It’s highly likely you’ve planned at least a two night stay so 10amp trickle charging (portable UMC) will do the trick. For something a little faster the RAC resort in Monkey Mia has a type 2 outlet, to use this you require a BYO type 2 to type 2 cable.

As per usual I highly recommend making full use of the Plugshare app, be sure to browse recent comments at each location you plan to use.

Carry a KHONS 3 phase cable or EVSE as a back up, you will notice many Tesla destination chargers in regional areas have a 5 pin 3 phase outlet nearby, so if the Tesla charger fails drivers have a plan B.

Pro-tips

Add in an extra day or two and make a side trip on the way back via Kalbarri, Port Gregory and Horrocks, we’ve stayed overnight at all 3 of these locations with 10amp trickle charging easy to find.

No matter how hot the forecast is for Shark Bay take a jacket, the afternoon south-westerly can get fairly cool by sunset.

Overall just plan correctly, take your time and enjoy the drive.

Why do my tyres wear faster than another Tesla’s tyres?

First up there is a myth that EVs wear tyres faster than a similar size petrol vehicle due to the extra weight. There has not been a detailed study on this and to be clear if there was a widespread study with dozens of vehicles over many years and large distances the far smoother accelerating and braking of an EV would offset tyre wear from the extra weight. The problem is the myth has a strong foothold so many EV owners use it as an excuse for their excessive tyre wear.

Tyres have a large amount of information moulded on to the sidewall.  As well as the sizing there’s also the speed index, weight index and tyre wear rating, a number normally between 200 and 500. A higher number suggests a longer lasting tyre but there is a possibility that a small amount of grip could be sacrificed so think carefully before changing from the tyres fitted in the factory by Tesla, especially the performance models.

So even after considering the tyre wear rating you’re still getting far less distance from the same tyre/vehicle combo as another Tesla owner, why could this be?

Poorly maintained tyre pressures – Stick to the cold pressures recommended by Tesla and check them on a regular basis. Keep in mind to check during the first few hundred metres of a drive before the tyres heat up.

A high amount of driving on coarse chip seal country roads.

A high amount of driving in built up areas with stops signs, traffic lights and most of all roundabouts.

Failing to rotate the tyres.

Possible misalignment due to a family member hitting a kerb or a pothole and not owning up to it.

And lastly, your driving style. No one wants to hear this but the combination of low centre of gravity and lack of engine noise lulls EV drivers into thinking they’re driving slower than they really are, but in reality your cornering faster, accelerating faster and generally putting the tyres under more pressure than you would in most petrol cars, continually driving like this scrubs the tyres out in no time at all.

Charging an EV at Caravan Parks

Over the past 7 years we have stayed in every state and territory of Australia and charged overnight at well over 100 different caravan parks, cabins and other accommodation that fall under the category of tourist parks.

There are some great sites, many over the top with attractions that never existed 30 years ago. Some are dusty, run down, patched together and best described as rustic. Some owners and managers are very EV friendly, others spend too much time watching Sky After Dark and will grudgingly let you plug in only to provide a running commentary on why EVs are City cars (even though you’re at a site 1200kms from Darwin). The one constant is getting a charge is always possible and, although slow, extremely convenient while you’re  relaxing.

The majority of locations have enough power to supply a full park of Caravans or RVs on a hot afternoon. However be aware that some have issues due the business expanding faster than expected, they are pushing their luck and eventually come unstuck just before dinner time on a hot day when the power shuts off. This shouldn’t be happening with a correctly build power system but on the rare occasion it does. Generally the power outage forces all the Grey Nomads to shut off their air-conditioners and venture outside thus easing the load when power is restored. A second issue to look out for are power outlets in poor condition due to having a hard life from careless tourists and a harsh coastal climate. If you think the power outlet looks dodgy find a better one, always take the safe option.

Tourist Parks factor in the cost of electricity to any site fees, a powered site is normally $8 to $15 more than an unpowered site. That does not mean you have full rights to plug in and charge for 20 hours straight, random power consumption of non EVs has been factored in not an EV potentially consuming 60kwh on one nights tariff. On most occasions I would suggest you offer to pay extra to charge the car, especially at a smaller privately owned business, very often the reception will refuse payment because you asked politely. Remember to wear your diplomatic hat for the benefit of you and the following EV owners.

Tips when plugging in:

Avoid using extension cords when possible. The only time I’ve needed one is when using a Tesla Gen2 UMC with the flat plug, these are difficult to fit it to many power bollards. If you do require an extension cord use the shortest 15amp possible.

Avoid making your charging cable a tripping hazard, keep some slack on the ground under the charge port and tape the cable to the lower section of the bollard so charging doesn’t get interrupted by someones foot on a dark evening.

If you have plenty of time to get enough charge required for the next leg of your journey set the amps lower and charge slower for longer, this way there’s less chance of any charging interruptions that could delay your morning departure.

Don’t be concerned about charging in the rain but do keep the charging unit off the ground in low lying areas as most tourist parks have firm ground with poor drainage.

Last of all don’t forget to turn off your air conditioner while charging, if you don’t plan for this extra consumption the charge percentage the next morning will be far less than expected.

The Downsides to Road Tripping with a Tesla Gen2 UMC plus Tail

The Tesla UMC Gen 2 (mobile connector) was introduced into Australia in mid 2019, all Tesla’s ordered before July 9th 2022 were provided with this charging cable for free, any buyers who ordered cars after that time have the option of purchasing from Tesla for $550 or looking for an aftermarket alternative. Many choose to stick with the Tesla product as it’s still one of the lower priced cables available.

Most owners make use of the included 10amp or 15amp plug. For home charging this provides enough charge for drivers that average up to 120kms per day, keeping in mind that the average Australian car of any fuel type travels only 38kms per day.

A common practice among Tesla owners is to purchase what is known as the Tesla UMC to 3 phase tail (approximately $150). This is a well made adaptor that connects straight into a 5 pin 3 phase outlet, this increases the potential power available to 32amp single phase, very handy for home charging if the electrician installing the 3 phase socket gives it the all clear. A Tesla owner could then add up to 300kms a day while parked at home.

Despite its low price and versatility at home the 3 phase tail has an Achilles Heel when used in regional areas on long trips- it’s NOT 3 phase, it’s only single phase.

The downsides:

  • A Tesla model 3 or Y have an 11kw 3 phase onboard charger, 11kw is only possible when the car is connected to a power source with a minimum of 3x 16amps, most 3 phase outlets in regional areas are 20amp or 32amp so that’s not an issue, the issue is the Tesla Gen2 UMC plus tail is limited to 32amp single phase, that’s 7.4kw from a 32amp outlet, or 5kw from a 20amp outlet. A prime example of how crippling this can be is at Border Village in South Australia, where the power outlet is limited to 20amp 3 phase. A Tesla using the correct 3 phase cable can charge at 2.4 times the speed as a Tesla using the Gen2 UMC. Border Village is one of the better roadhouses but hanging out there for many hours longer than necessary should be avoided.
  • A correct 3 phase cable (also known as an EVSE) drawing 16amps from each 20 or 32amp wire is unlikely to trip the breaker even over a long charging session, drawing 32amps through one phase for hours on end adds to the possibility of tripping a breaker, that’s not a situation you need while asleep or away from phone connection.
  • Lastly, drawing 32amps single phase on a site with low generating capacity at certain times of the day can cause the maintenance chief to get a bit agitated, a reliable electricity supply is critical to regional locations, at least one regional roadhouse that I know of has now barred EVs from charging after 7 years of goodwill.

What cables are best:

There are a number of 3 phase EVSE cables available including the high priced but extremely tough Juice Booster 2, the Kwik Mode 2 EV charger or the KHONS 3 phase charger. All have type 2 plugs on the car end and are easy to operate and store.

Over the past 7 years I’ve plugged into the vast majority of official Plugshare 3 phase outlets across Australia, I can confidently say if you use the correct equipment your journey will be smooth, if you try and save a few dollars you’ll soon regret it.

How to find Free Charging, some Hot Tips from a long term EV owner.

To be very clear if you purchased a $70k+ vehicle and saving money on refueling is the only focus you’ve missed the point, lower long term servicing and repair plus the far longer lifespan of a Tesla are just as important. Throw in the high safety rating and the additional storage a Tesla provides and ownership is a broad package.

Without doubt the best EV charging is at home, even 30 cents a unit grid power is at least half the price per distance driven than a similar size and performance petrol car. If you charge off peak, even cheaper. Those using home solar are reducing their fuel cost by up to a factor of 8. Best of all parking at home is safe, no door dings from lazy parking, no stray shopping trolleys, there’s big savings to be made from avoiding the panel beaters.

What about all those free Tesla destination chargers? These are not free, they’re complimentary, almost all Tesla destination chargers are owned by a local business that have installed them to support EV owners. The electricity is not paid for by Tesla, it’s paid for by the small business that would prefer you drop in and buy a product rather than you sitting in your car watching Netflix.

Is there an app that shows all the free chargers? I get asked this question often in public and the answer is “not specifically”, the best way to find them is to log on to Plugshare, find the busiest and always in use chargers in the metro area and its a sure bet they’re free.

So what is the best free charger in WA? The one at your home, it’s never ICED, it doesn’t require an app, you won’t get panel damage and best of all it’s free to use any time you like.

While on the subject of free, TOCWA have a free loan of charging cables and spare tyres for members, membership is $20 per year via this link.

TOCWA Big Lap Returnees Meetup

Join us on Saturday to celebrate the safe return of two Model Ys that have successfully simultaneously driven around Australia in opposite directions and celebrate Pete Petrovsky becoming the 22nd person to drive around Australia in an EV.

Model Y’s safely retruned from their odyssey

Saturday 17 September 2022 at 10:30am at:

Valley Social – 8731 West Swan Rd, Henley Brook

Casual meetups are open to everyone including those who have never seen a Tesla before.

It’s an ideal opportunity to meet club members and to see the cars in the flesh which we are all passionate about.

It’s also a great way for new owners to learn more about their cars and to share in the vast pool of knowledge gained by other members.

We hope to see you there and look forward to chatting about all things Tesla.

So you want to drive an EV across the Nullarbor?

Clearly the quicker (and possibly cheaper) option is to travel across Australia on a commercial jet, so if you’re not sure you have the patience and planning skills take the airport option. For those more adventurous read on.

By late 2023 the WA state government will have enough fast DC chargers installed between Perth and Eucla to provide a fairly comfortable trip, once you get into South Australia its anyone’s guess, SA do have a charging rollout planned but it’s very Adelaide centric, so for the next 12 months or so most charging requires knowledge and patience.

To keep this a moderate length read I’ll focus on the drive between Port Augusta and Norseman, a distance of 1,670km. There is  already an article on TOCWA’s website discussing the Perth to Kalgoorlie section.

The road – It’s generally good the whole way with a long sections of chip seal surface that increases energy consumption. There are no overtaking lanes but considering it’s mostly flat and straight with good visibility overtaking is relatively easy. Despite the road being good I highly recommend you take a full size spare tyre and wheel combo, in the unlikely chance you get a tyre issue it will be a major one rather than a slow leak from a tech screw. Be aware Roadhouses don’t replace tyres, they sell fuel, food and drink.

What to do/take:

  • Make sure your cold tyre pressures are correct, keep monitoring those pressures throughout the journey.
  • Study Plugshare thoroughly before you leave, especially the comments. While charging during the journey check Plugshare for your next stop just in case there’s any late changes. Always check into Plugshare so other EV drivers on the Nullarbor can plan ahead.
  • Take the correct charging cable plus plan B and C cables. The correct cable is a 3 phase Juice Booster 2 or KHONS cable, the Tesla GEN2 UMC to 3 phase tail is a plan D and should NOT be used on Nullarbor 3 phase outlets unless you’re desperate.
  • I can not stress how important it is to follow the mantra of ALWAYS BE CHARGING, do not cut your charging session short at a working charge point because you think the next one is faster or cheaper.
  • Telstra is the only choice for any chance of phone reception (of course if you fit in your roaming Starlink dish you’re king of the Nullarbor).
  • Keep yourself busy and the charging time won’t appear so slow, Nullarboring is a term used by people with no imagination.
  • Have the BOM app on your phone – The air temp and wind direction can have a big effect on your range, plan ahead and add more charge than you require to be safe.
  • Take a relaxed attitude about the facilities, most of the infrastructure is pre 1976, it’s generally clean but worn out. Producing clean water, electricity and keeping everything operational is expensive due to being so far from a capital city so don’t expect much value for money. Take note that due to staff shortages most locations have cleared up the dishes, closed the bar and hopped off to bed far earlier than you expect.
  • Wear a Diplomatic hat – like much of the country, regional areas are struggling to find staff, those on site are working long hours, you are one of a hundred customers that day. Keep in mind by allowing EVs to charge Roadhouse management are doing you a favour rather than making a profit from selling electricity.
  • Understand that some new staff members have no idea the business has a charge point, it can be a interesting conversation.
  • Leave early arrive early, getting on to the road just before sunrise is a great way to start the day, plan your first charging stop for a late breakfast. Traffic is almost non existent in the early morning, visibility is good and it’s easier to spot wildlife. By late afternoon it’s best to be parked up with the car on charge while the rest of the tourists are frantically racing to their next destination while driving into a blazing sunset with no hope of seeing a Roo about to smash the headlights.
  • Take into account as you drive east you’ll lose an average of 15 minutes of daylight every 400kms, on the drive west you’ll gain 15 minutes.
  • Be very aware of the change in time zones as the Nullarbor also has its own AWCT time from Cocklebiddy to the WA border, you may roll up to a Roadhouse thinking its 6.30pm when it’s actually 7.15pm and the staff have locked up for the evening.

What not to do:

  • Do not plug in without seeking permission, if you have a passenger get them to go seek out a staff member while the driver parks up and gets the cable ready.
  • Do not Hypermile, it’s not necessary with the biggest gap between chargers being 200kms. It may be okay to drive slower in the early hours of the morning when the roads are virtually free of traffic but during daylight hours anything less than 90kmh has the potential to aggravate other road users.
  • During overnight stops don’t try and charge too fast if you don’t need to, plan to have your car finish charging just before expected departure. If you charge at the highest rate and the breaker trips during the night you may not realize and could end up wasting time in the morning.
  • Do not turn off the air conditioner on warm afternoons, a warm interior reduces driver concentration, set the aircon to 22.5C and all will be fine.
  • Do not drive fast through the RH car parks, most are Limestone and can be in poor condition with cavernous potholes that are difficult to see, on most occasions it’s less than walking pace or you may end up rattled.
  • Don’t plan to drive too far in one day especially if you’ve booked accommodation in advance.

Port Augusta

It’s difficult to understand why PA doesn’t have DC chargers considering its on a T junction of 3 busy highways. There’s two AC charging options in town, we prefer to use the Majestic Apartments that are centrally located and very secure. The accommodation is very nice with washing machines and dryers in the rooms. Although it’s not necessary to be a guest to use the Tesla HPWC it’s wise to ring at least half a day in advance, ask permission and provide an accurate arrival time, that way the staff will place a witches hat in front of the car charger and open the security gates when they see you pull up. Reception normally refuse payment, a big thank you and some quality chocolate won’t go amiss though. Coles, Woolworths and Big W are all within 200 metres so you can stock up before heading west.

Kimba

Milton tyres has been generously offering EV charging since May 2016, they recently upgraded to a 32amp three phase outlet that makes charging even easier. Payment is dependent on the length of stay. Keep in mind that unless prior arrangements are made this service is only available during business hours Monday to Friday.

Poochera

This town is almost deserted but it has gem of a little old country pub with a 3 phase 32amp outlet that’s easy to access. The bad news is the Pub doesn’t open to 4.00pm, the good news is you can ring ahead and arrange payment via BSB. Jeff and Karen have kindly offered this service since May 2016 after a visit by WA Tesla owners Matt and David.

Ceduna East-West Motel

There’s two Tesla HPWCs with handy parking, payment is currently $25 at reception before plugging in. I highly recommend you take the 10 minute walk to the Ceduna Foreshore Hotel for a meal.

Penong Caravan Park

This location has handy 32amp 3 phase outlet located in the centre of the Caravan Park, payment is a $10 service fee plus 40cents a kWh, the service fee includes the use of the facilities such as showers and camp kitchen. Penong is another example of friendly South Australian country people making up for the lack of government support emanating from Adelaide.

The Nullarbor Roadhouse

The 3 phase outlet is on the rear of the main building to the left hand side as you look from the road, payment is $30 via the Cafeteria. Add plenty of extra charge at this location as a coastal headwind driving west could leave you struggling to get the next charge point.

Border Village

As you may see from Plugshare comments Trevor is the go to person at this location, ask for him at reception and he’ll guide you around to the rear workshop. Charging is strictly limited to 20amp 3 phase, that’s okay if you have a model 3 or Y drawing 3 x 16amps but it’s also where the Tesla Gen2 UMC to 3 phase tail comes unstuck, charging at 20amps single phase is unnecessarily slow. Charging is complimentary in the hope that you’ll sit down for a meal or stay overnight.

Eucla

This site is no longer allowing EV charging.

Mundrabilla

This site has a 32amp 3 phase outside one of the motel rooms, payment is $40 all you can charge but management would much prefer charging in daylight hours or at least avoided between 9.00pm and 6.00am due to the electricity system they have in place.

Pro tip- Stand just inside the roadhouse doorway to gain Telstra reception.

Madura Pass

The good news is Madura has a crowd funded 22kw DC charger in the old garage next to the fuel bowsers, the bad news is that due to staff shortages the garage door is only open from 7.00am until 5.00pm. I would advise not to arrive in the late afternoon as at 5.00pm the power is switched off, the doors closed and the fuel attendant rushes off to serve food in the bar, such is life on the Nullarbor currently. Be aware that all but one of the staff at Madura are extremely friendly, unfortunately one has an allergy to Electric Cars and is best left alone. Payment is a donation to the RFDS.

Cocklebiddy

An easy 32amp 3 phase to find, right next to the large Eagles cage with a sign that says TV outlet. The sit down meals here are always worth a try.  RFDS donation for payment.

Caiguna Roadhouse

This location has the famous Biofil DC charger that was installed in January 2022, this 50kw unit is powered by a converted diesel generator that consumes used cooking oil from the roadhouse kitchen. Despite some difficulties with solidified fuel on cold winter mornings the Vegpod has served its purpose by encouraging the WA state government to extend the DC charger network across to the WA border. Payment is a $50 service fee plus cost for energy used, staff are required to start to unit. Update 5/11/2022: Nullarbor Roadhouses are still struggling to find staff, Caiguna employees are extremely busy and will start the generator if you contact them well ahead. My suggestion is to avoid stopping here for a DC charge until their circumstances improve. By all means stop in and grab some food and drink or charge from 15 amp overnight.

Balladonia

At the rear of the western side of the main building is another crowd funded 22kw DC charger, the payment is $1.00 per unit as recorded on the DC chargers screen. You will need to go into reception first to get a key. Be patient and follow the instructions exactly or the whole 2 minute process will have to repeated. Be warned, don’t skimp on charging here because it’s $1 a unit and the next location is a flat fee for all you can charge, that method may leave you short of range and possibly stranded.

Norseman

Ring at least half a day ahead during shire office hours and arrange the $37 payment via BSB or dropping into reception (a 7 minute walk from the 3 phase outlet at the oval). Make sure you provide contact details and your number plate as one or two greedy EV owners have plugged in without prior arrangement. If you walk for 4-5 minutes directly east from the oval you’ll locate some public toilets and a laundry.

Rob and Robin have crossed the Nullarbor 5 times in their Tesla Model S and charged at each location multiple times.
