Road trip charging with Tesla
So, we’ve finished a road trip with our Tesla from Sydney to Brisbane and back. Since people mentioned a lot about range anxiety, I would like to emphasize how it went when talking about charging.
I’m pretty new in the EV field and just owned a Tesla Model 3 about 5 months ago, and haven’t really done any road trip that requires charging along the way. This is the first time.
Distance: 900Km, aiming for a single day of driving.
The strategy that I’ve learned is: Stop at any fast charging point every 1–1.5 hours.
On the first trip from Sydney to Brisbane, we only stop at the Tesla superchargers, which means resting after 2 to 3 hours of driving. The thing is we have to stop multiple times because the kids need the restroom. Basically, we have too many snacks and drinks when on the road, which makes us go to the toilet more often. Those public toilets have no charger, so the car is just waiting without doing a thing.
On the way back from Brisbane to Sydney, we decide to stop multiple times at any fast charging point. There are a lot of them, such as Tesla superchargers (120Kw), NRMA chargers (50Kw), Chargefox (120Kw), Evie Networks (350Kw). And they all have restrooms nearby.
Here is the thing I did:
- Find the next fast charging point that is 1–1.5 hours away from the current location, using PlugShare app.
- On arriving, plug to charge the car and go to the restroom. Some chargers may be close to a shopping mall or a playground, so I can stay longer while my kids playing or my wife buying something.
- Then go and find the next charger again.
The slowest fast charger is 50Kw, so we can top up 12Kwh at least when stopping for 15 minutes. And with the supercharger at 120Kw, we can add to the car around 25Kwh in 15 minutes. If we alternate between them, we can top up 37Kwh in 30 minutes total.
With the average consumption of 160wh/km, that 37Kwh would let the car goes for 230Km. Assuming the average speed on M1 highway is 100Km/h, we need 2 hr 20 min to go that far.
So basically, driving an hour and stopping at a Tesla supercharger for 15 minutes, then driving another hour and stopping at a 50Kw charger for another 15 minutes, and then the battery level is back at the initial state.
With this strategy, we can go to the end of the earth, without worrying about being out of battery.
