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’ll be fine. Depending on the power of your home charger it might struggle to charge at -10f, especially if it has an LFP battery pack, but just left out it will be fine. Make sure to turn sentry mode off.
