Patent ID: 7013659

Claim:
A battery cooling system for cooling a battery mounted on a vehicle by using conditioned air of an air conditioner, the air conditioner comprising: a compression device for compressing refrigerant, the compression device disposed to control a compression capacity; an air conditioning case for defining an air passage through which air flows, the air conditioning case having an air outlet portion from which air is blown into a passenger compartment of the vehicle; a cooling heat exchanger for cooling air by using refrigerant from the compression device, the cooling heat exchanger being disposed in the air conditioning case upstream from the air outlet portion; and an air-conditioning control unit which controls a cooling capacity of the cooling heat exchanger by controlling a compression capacity of the compression device, the battery cooling system comprising: a battery case for accommodating the battery, the battery case having an air supply passage through which air inside the passenger compartment is introduced to be supplied to the battery; a blower disposed in the battery case for blowing air introduced into the air supply passage to the battery; and a battery control unit which controls the blower to increase an air amount supplied to the battery when a predetermined condition is satisfied, wherein the air-conditioning control unit decreases the compression capacity of the compression device after the air amount supplied to the air supply passage of the battery case is increased to a predetermined amount.
