I will be leaving my 2022 Model Y with my son for 4 months this winter. It will be kept outside and he does not have an indoor charger. He lives in Croton, NY and the weather can get extremely cold in the Winter. The closest Supercharger in only 15 minutes from his home. I realize cold temps reduces the range substantially. In order to keep the battery warmer, would you recommend I purchase the Tesla Mobile Connecter and have it plugged into the 110W plug from the garage? Or, do you think it's fine just leaving it parked outside in the cold and driven a few times a week to charge at the supercharger.
