Probably a noob question, but when charging is complete does the car cut off power reception from the charger? Or does car communicate this to the charger which stops sending in more power? Or does it keep charging slowly to maintain the full battery? Does this depend on chargers? Finally got the charger set up after more than a week, only to realize that I know so little about it. My garage uses a clipper creek charger, I forgot which model but it has 40A output. I just set up the charging 30 minutes ago and it should finish at 80% in an hour. I really want to know what will happen after that and if I need to do anything at all (I know probably not but just want to be sure).
