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?
Not to gatekeep cold, but block heaters aren’t a thing most people use when it only gets down to -12C. I grew up in a Labrador where they were heavily used, but nobody in Nova Scotia, where I moved to in my 20s, uses them.
