My son has a Bolt in Alaska and he has a short 3 mile commute but has to go to max heater energy just to keep the windows defogged. I notice that too down here in Marland.
Humans put out a LOT of breath andhumidity and in the cold that is all going to condense on the window. So he uses pre-heat and conditioning Fully HALF of his battery energy goes to defrosting and heat. But with p re-heat, it does not affect range that much. But is certainly a contributor to EV design bob Bob On Mon, Dec 20, 2021 at 9:33 PM Mike Chancey via EV <[email protected]> wrote: > > I am told GM can't do over the air updates on the Bolt except to the > infotainment system, and they have never bothered to do that.
