Tesla is Wise to Open Up its Superchargers in Australia

As you may have seen Tesla have opened up 5 sites in NSW for use by non Tesla Electric Vehicles, the first of many sites that will open up partly due to being NSW state government funded but also due to being in areas with low Supercharger use providing a great opportunity for Tesla to make better use of assets. As time passes it’s fully expected Superchargers will open up at many locations across Australia.

Dubbo Supercharger

Why is this a wise move?

  1. As mentioned above making better use of assets is beneficial to Tesla, rarely used Supercharger stalls getting 79 cents a kWh is far better than sitting empty for most of the day.
  2. The more high paying customers Tesla have the higher the incentive to expand at a faster pace
  3. A highly reliable working Supercharger network is great marketing for Tesla, a good example are sites in Dubbo, Tamworth and Bathurst when we visited those locations in late 2022 ours was the only Tesla Supercharging, yet on each occasion the nearby generic DC charger was broken. Non Tesla EV drivers may soon realise that not only does Tesla has a better product in terms of charging but also Tesla is an auto maker that actually care about after sales service.

Tesla can’t build the nations DC charging infrastructure on its own, unfortunately the alternative to Tesla DC charging infrastructure is in a poor state with no signs of improving, there doesn’t appear to be much urgency to keep the equipment reliably maintained, if competition for charging dollars doesn’t motivate some changes I’m sure the various governments who hand over large amounts of taxpayer dollars to install chargers will be motivated to carefully choose who the money goes to.

Will a Solar Specific Charger Save You Money?

The short answer is it’s often unlikely but it’s not always about the money so please read on.

To clarify a solar specific charger is a device that detects home solar input and can be set so an EVs charging amps will not be higher than the excess solar available, for instance if the sky becomes cloudy and solar input reduces so will the EVs charge input.

If you have a neighbour that loves calling your Tesla a “Coal burner” there’s no better way to shut down the claim than by charging 100% from solar power, a solar specific charger is a good way of achieving this. As your neighbour is already too thick to understand electric motor efficiency they won’t be wise enough to work out you’re not saving any money by charging via a sometimes expensive piece of equipment.

Perth is the sunniest capital city in Australia – Yep, even sunnier than Brisbane in the sunshine state. During daylight hours the sun shines on average two thirds of the time in the Perth area so installing a device that only allows solar to charge an EV is redundant for two thirds of the time.

Combined Installation and unit cost – This varies by a large margin so it’s best left to a case by case basis, what is important is to get an accurate dollar figure on the difference between a fully installed solar specific charger and a fully installed “dumb” (generic) unit that continues charging at the same amps. For instance if Tesla have provided you with a free Gen2 UMC that you plan to plug in to an existing 10/15amp wall socket your installation plus unit cost is zero dollars. If you’re considering a $750 Tesla destination charger (HPWC) with a $750 installation cost your total cost is $1500. Keep in mind $750 is an example as installation costs are wide ranging.

Now as an example if you get a quote of $2000 for the solar specific charger plus $750 installation the extra upfront cost to charge directly from solar is between $1250 and $2750.

How long will the payback on investment be?

Once you have a fixed and trustworthy quote and you also have a firm understanding on how many kilometres you plan to drive per day using home charging use the below chart to do some calculations. If you’re not sure about driving kilometres yet a good guide is this, the average passenger car travels 38kms per day in Australia.

I’ve factored in a unit cost of 30 cents from the grid and the 2023 feed in the tariff of 3 cents per unit, this provides a potential saving of 27 cents for every kWh of solar going direct to the car. Keep in mind that In Perth across a whole year the sun is shining 2/3s of the time anyway.

The decision to install a solar specific charger is up to you, just think through these questions:

  • Do you drive enough distance per day to justify it?
  • Do you plan to charge from home during the day on an almost daily basis?
  • Do you have enough excess solar?
  • And does the units warranty period match your expectations?

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.

Tesla Dominate EV Sales Figures, But Why?

The recently released EV sales figures by the EV Council of Australia provides a stark reminder of how poor the generic (non-Tesla) charging infrastructure is in this country.

The EVCs figures show that 3.39% of all light vehicles sales for Q1,2,3 2022 were electric, this includes Plug-in Hybrid Vehicles (PHEV). When those figures are broken down it also shows that two vehicles dominated EV sales, the Tesla Model 3 and Tesla Model Y, these two variants alone made up 53.2% of EV market share, the other 46.8% was from a combination of 93 variants. If you remove the 35 PHEV variants from the figures Tesla has a 64% share, it also shows that despite the Electric Vehicle Council highlighting a figure of 3.39% the reality is removing Tesla and PHEVs from the sales figures reduces this to 1.007%, in effect the 58 variants of pure EV that do not have a Tesla badge make up just 1% of the light vehicle market. This large difference in sales between Tesla and the remainder is made even more interesting when you consider Tesla do not spend money on advertising.

From State of Electric Vehicles October 2022 report

Despite claims of purchase price and lack of choice deterring Australians from buying an Electric Vehicle I have no doubt the biggest barrier is a fear of being unable to charge away from home, petrol and diesel vehicles have been extremely convenient in regional areas for decades and the buying public expect no compromises. For a Tesla owner who lives close to or between one of the 5 east coast mainland capital cities charging is reliable and convenient due to the Tesla Supercharger network, in the south west of the country Tesla owners have a similar convenience. Each location has a minimum 3 and sometimes 8 charging cables, the reliability rate is extremely good. On the other hand, non-Tesla EVs (legacy auto) must rely on a mix of different branded chargers with a variety of payment systems. These DC chargers are few and far between with only 1 or 2 units at each location and many being broken or out of operation for weeks at a time, the situation is shambolic and the EV buying public are becoming very aware of the problems. Tesla currently have only two variants of EV for sale in Australia with an average purchase cost of $80,000, price and lack of choice has very little bearing on a sale, a convenient and reliable charging infrastructure does.

Unfortunately, the Federal governments promised “DC chargers every 150kms” is just a talking point that will continue through to the next election. Every month of delay is crushing legacy auto while at the same time helping cement Tesla as the dominant sales leader for many years.

You cannot charge Electric Vehicles from media releases.

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 built 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 has 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.

Juice Booster 2
Kwik
Khons

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.
