Polestar 2 has 78kWh battery with 75kWh available but apparently there are buffers both top and bottom end. 90% is probably a reasonable figure for regular charging. The new recommended level is, I suspect, more for marketing reasons than technical given the poor economy. JLR had A similar challenge when they upped the range?Interesting. Ipace owner here. Possible P2 in my future. Jaguar just says charge to 100% as much as you want. Won't hurt. I know Tesla also doesn't recommend charging to 100. The Ipace keeps a large buffer of 5 kWh to protect the battery (90kWh with 84.7 available). I thought the P2 also did this? I haven't seen any battery degradation after 1 year / 19500 km. The Tesla seem to drop up to 5% in first yr.
That was my point. My 75kWh figure was taken from the Polestar website - I can’t find it now but it was definitely there in the early days when I was researching the car.Surely there is a bottom end buffer as well? (i.e. you can never actually drain the battery totally.)
