My 2016 90 S with 44K miles is not charging at all. Outside temp is 10 degrees F I have it plugged into a 40 amp 240 volt destination charger. I called Tesla service and they said turn on the heat and let the car warm up. I did. For 4 hours the interior temp was at 90 F. Nothing. There are enough amps at the charger to heat the battery pack because once the car was warm the amp draw came down to 15/30 It seems that the Battery Management System (BMS) is not functioning because if it were it would have warmed the battery sufficiently to allow it to accept a charge. It has now been connected to the charger overnight and the battery has lost 2 miles of range while being plugged in. Any suggestions?
