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?
IIRC there were stories from a few years back that danced around this question. The one I’m thinking of is a guy who parked his car - a Bolt? - in the top covered corner of an airport garage. I want to say DTW, might have been MSP. He reported it was windy as well.
It was also at least a week so definitely cold soaked. IIRC he left home with a full charge, was at like 65-70% when he parked it. Getting back the car did start but was sluggish until it fully warmed up; took at least 10-15 minutes.
Personally I’d have AAA ready JIC, almost no matter what the car was. That’s just good risk management though, and not necessarily anything to do specifically with EVs.
