Thanks for your reply! The car will be at home. I’ll be getting a cover for it to help against the elements. BMW sales tells me that a full charge of the EV battery will keep the 12V from depleting but I’m always questioning things. Maybe i should ask the service center instead.
I think I’ve read somewhere that the newer cars have that capability but i wanted to make sure cause i don’t want to come home and find out my car won’t start.
