Abstract: An electric vehicle cooling system includes a vehicle control unit (VCU), a coolant pump controller, a motor controller, a motor, a vehicle charger, an electronic coolant pump, and a cooling plate. The electronic coolant pump, the vehicle charger, the motor controller, the motor, and the cooling plate are connected in sequence to form a closed coolant loop for a coolant.
