The battery barrel effect will cause the battery to charge. The BMS system detects that the battery has entered the overcharge protection in advance. In fact, only one of the batteries is full, or let The BMS system detects that the battery enters the over-discharge protection state, which is actually caused by over-discharge of one of the lower-voltage batteries. After the device acts, each battery voltage reduces the capacity attenuation caused by the battery barrel effect and prolongs the problem.
