302 -In addition to controlling the discharge contactors, the discharge controller calculates and transmits to the upper-level system the maximum allowable current value with which the modular battery can be discharged ("Discharge current limit"), as well as the maximum regeneration current value with which the modular battery can be charged during operation under load ("Regeneration current limit"). The calculation of the discharge current and regeneration current of the entire battery is performed based on the number of battery modules operating for discharge and the maximum discharge and charge current values ​​transmitted by them.
