DYNAMIC OUTPUT CONTROL OF VEHICLE CHARGERS WITH RESPECTIVE INTERNAL BATTERIES

Electric vehicle (EV) charging stations for: (i) preventing damage to a battery of an EV charging station, and (ii) maintaining fast charging of the battery of the EV charging station. An EV charging station controller determines if an input power to the EV charging station is above an input power threshold value, and, if so, determines if a charge level of the battery of the EV charging station is below a low charge threshold level. If the charge level is below the low charge threshold level, a portion of the input power may be reserved for the battery of the EV charging station.
