In these conditions, sometimes the temps fall even lower, and people will take their ICE batteries inside to prevent it dying. Can’t do that with an EV, and can’t leave it charged for two weeks. The EV I have in mind can run its own heater periodically to prevent damage. Could I count on it doing that for the entire vacation?
I fly from Norway to France every Christmas for ca. 2 weeks, and always left my Zoé at the open air car park at the train station, where it experienced -20°C.
Never had any problems, maybe lose like 3% battery.
