EV Driving

Having done a long drive into France not that long ago using an EV (a 2020 Polestar 2), I encountered some stuff that I thought was worth writing down.

Charging

Let’s get some of the obvious stuff out of the way first. Yes, doing long trips in an EV requires a little bit of upfront planning so you wont run out of spark along the way. EVs also don’t have the same range as a petrol or diesel car, so you’ll need to stop more often.

Polestar 2 battery state API

Update in 2024:

It appears that Polestar is working on a proper API and folks have been figuring out how to get to the data used by the mobile app. See here for an example of a custom Home Assistant integration that surfaces quite a bit more than just the state of charge. This code will still work even with the existence of a polestar API but be aware that an official API might at some point appear.
