Abstract

The present solution is directed to control of maximum current for regenerative charging of an EV battery. A battery management system (BMS) can facilitate, responsive to a first action by an actuator, a discharge of an EV battery. The BMS can identify, responsive to a second action by the actuator, a discharge capacity of the battery corresponding to the discharge associated with the first action. The BMS can determine, responsive to the second action, a temperature measurement and a state of charge measurement of the battery and determine, based on the temperature measurement, the state of charge measurement and the discharge capacity, a derate factor that can be used to modify a current level supplied to the battery during charging of the battery from energy generated responsive to the second action. The BMS can cause the battery to be charged according to the modified current level and the generated energy.
