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?
The problem with ICE cars starting in the winter is a combination of low temperature for the battery, thus reduced power AND cold engine oil, wich is more viscous, so one needs more power then normal to start the engine cranking AND cold engines are noticable for having a harder time to start combustion, wich is remedied by preheating and higher speeds from the starter, wich again needs more power.
