The calculation of the charge, discharge and regeneration currents of the entire battery is performed based on the number of battery modules operating for charge or discharge and the maximum charge and discharge current values ​​transmitted by them:
298 +
299 +* "Charge current limit" and "Regeneration current limit" are calculated only if there is "Charge request";

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.
