Hi to all members of this forum. we are having some issues with a car, battery was swapped, used, the used BMS was re-deployed and the car started run and drive. but, we can not charge the car. when we CP opens, there are no lights on it, not red or blue or green. we drove the car and saw no issues coming up on the MCU. Well, we drove and then all the charge went to 0 miles. no charging or regen.again no alerts. what could be the issue with this car? thank you in advance
