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.

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. Edit: it has become very apparent that the number of EVs crossing the Nullarbor have increased significantly through November and December 2022, there is a chance you could arrive at a charge point that is already in use, it is in your best interest to plugshare your journey so other drivers can liaise with you. The simple 30 second task of checking into plugshare by yourself and other EV travelers could save you 3 or 4 hours of wasted time at the next charge stop.
  • 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.

Driving a Tesla from Perth to Kalgoorlie

The drive towards Kalgoorlie is generally a little more difficult than the return journey due to Kalgoorlie being 450 metres higher above sea level than Perth. The extra 15-20kms range your car will consume heading east requires a bit of extra charging time along the way, not much but it should be factored in. Of course a strong tail wind or head wind will reduce or increase charging times. We know that by late 2023 Synergy will have installed multiple fast DC chargers at 2 or 3 sites along this route making the journey far more comfortable, until then it’s AC charging all the way.

The road – The highway between Perth and Kalgoorlie is mostly in reasonable condition but considering the importance of the Goldfields to the WA economy I believe it should be better. There are still a few sections lacking overtaking lanes and a few areas with poor drainage that create potholes easily, there are not many but keep a sharp out each side of Merredin. Don’t drive slow on this highway as you’ll just aggravate other drivers, 95 in a 100 zone is okay, keep in mind that most vehicles on this road are part of a business and don’t have time to sit behind a Tesla that didn’t charge enough at the last stop.

Perth GPO to Kalgoorlie is 593kms with 3 useful (and reliable) AC charging stops along the way, Merredin, Southern Cross and Koora Retreat. Most vehicles could get by with one stop at Merredin although I suggest you stop at all three to break up the journey. The overall trip will take the same time as AC charging speeds are all equal. Merredin is a friendly little town for a first time visitor but eventually you’ll want to keep moving. On the return trip to Perth I 100% recommend you charge at all 3, you’ll be none too pleased if you bypass a perfectly good charging option to find the next one being used by another EV.

If you’ve never driven this trip before I highly suggest you leave home early to arrive early, this way any unplanned hurdles won’t leave you crawling into Kalgoorlie after dark, hungry and tired. If you can get through Midland and into Mundaring before morning peak traffic you’ll set yourself up for a comfortable day, the end game is to be in Kalgoorlie before Sunset with your car on charge while you enjoy a well earned drink.

Merredin has two different useful charging locations, the most convenient one is the Tesla destination chargers behind the visitors centre, these are currently complimentary, don’t forget to pop in to the VC and thank the lady behind the counter for making a charger available.

Merredin Visitors Centre

Southern Cross has a very robust 3 phase 5 pin outlet at the Oval, it’s currently available 24/7 and free to use. You will require a 3 phase cable such as a Juice Booster 2 or KHONS cable. A Gen2 UMC with 3 phase tail will work but only through 1 phase restricting your charge rate, these are okay for home use but personally I think they’re a very poor option for country areas. I’ve never known Southern Cross to be ICED or broken but still plan to arrive here with at least 100kms of range remaining, there’s currently no other 3 phase options in town.

Koora Retreat installed one of the states first Tesla destination chargers as a way of helping the EV community, the original owners have moved on due to ill health but the new owner is keen to continue helping EVs. Payment is a very reasonable 50 cents a unit via BSB, follow the instructions on the paperwork inside the charging cabinet and be generous, without these charging options very few EVs would have visited Kalgoorlie in the past 6 years. Be aware phone connection often drops out near Koora Retreat, combined with the lack of signs and difficult to spot entry it requires a sharp eye to locate. The best guide I can provide is the entrance is 69.5kms east of Southern Cross.

How to make the car charge faster? Go for a walk, be a tourist, have a long lunch, talk to people, download and edit some photos. Keep yourself occupied and it won’t be a drag.

Finally Plugshare is by far the best option for Western Australia, ABRP is just an extra assistance for those that may need it. And don’t forget: Always Be Charging, Always Bring Cables, Always Browse Comments and Always Be Considerate/Courteous.

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.

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.

Nullarbor Roadhouse 32amp 3 phase

Nullarbor Roadhouse, 197kms drive from Eucla, has a 32amp 3 phase at the rear of the building close to the motel units.

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, Mundrabilla 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.

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.

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 AC 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 DC charger in Ravensthorpe is 21 kW. If the DC is in use you can also top up charge at Ravensthorpe’s Green Haven caravan park which has a Tesla destination charger that cost the owners more to install than they’ll ever get back from the 50 cents per kWh charging fee. Back in 2017 when no one in Ravensthorpe had any interest in EV charging Claire at the caravan park stepped up. 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.

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.

Duke of Orleans Bay.

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
