176 -In addition to controlling the charging contactors, the charge controller calculates and transmits to the upper-level system the value of the maximum allowable current, which can be used to charge the modular battery (“Charge current limit”). The calculation of the charging current of the entire battery is performed based on the number of battery modules operating per charge and the values of the current limits transmitted by them.
