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?
It will be totally fine, but if it is easy I would plug it in. Even to 110 volt outlet would be fine. Nice to come back to a remotely started warmed charged car.
