5 months in winter storage

Sat Aug 12, 2017 12:16 am

Hi

I'm in the process of buying a Bolt and I just want to make sure that I won't be damaging the car by leaving it in my unheated garage for 5 months each winter (mid-December to mid-May). I live in upstate New York so it will likely have periods of time below freezing (although not below zero). I see in the manual it says to leave the car unplugged, with only a few bars of charge, and to leave the 12 volt battery on an appropriate charger. Are there any concerns about the car automatically trying to warm up the battery if it gets too cold and in the process depleting the battery? Can the car (battery) handle being left each year for 5 months?

Thanks for any input on this.

Update: I just read the thermal management thread in this "Ask Chevrolet" section. So the question is whether being left in below freezing temps for an indeterminate period (very likely above zero F), damage the battery? Can I assume that if the car is unplugged with only a few bars of charge that the car won't use energy to try to warm the battery?

Would it be better to leave the car plugged in - set to hilltop setting (max 90%) - so the thermal management can warm the battery as needed? Does leaving the car at 90% charge for an extended period damage the battery?

Any insights or advice on this are greatly appreciated.
