331 331  The BMS Main X device supports active balancing of battery modules both in the process of charging and in the process of discharging the battery.
332 +\\When the battery is charging, balancing is performed by disconnecting the most charged battery modules from the common bus. Before disconnecting the modules, the BMS Main X sends a request to the upper-level system (charger) to reduce the charge current to zero, and after the current becomes zero, disconnects the most charged battery modules.
