To drive a battery cooling fan so which drive sound of the battery cooling fan becomes smaller than the drive sound of a blower fan of an air-conditioner, without using a transmission signal from the air-conditioner.SOLUTION: A vehicular battery cooling system which supplies air in a vehicle interior to a battery room by a battery cooling fan to cool a battery comprises a first temperature sensor which detects a temperature of the battery, a second temperature sensor which detects a temperature of the vehicle interior, and a controller which controls driving of the battery cooling fan. The controller estimates an outside air temperature outside the vehicle, estimates an output of a blower fan of an air-conditioner of the vehicle on the basis of a difference between the temperature in the vehicle interior and the estimated outside air temperature, and controls an output of the battery cooling fan on the basis of the estimated output of the blower fan of the air-conditioner and the temperature of the battery.SELECTED DRAWING: Figure 3
【課題】空調装置からの送信信号を用いることなく、バッテリ冷却ファンの駆動音が空調装置のブロアファンの駆動音よりも小さくなるようにバッテリ冷却ファンを駆動する。【解決手段】電池室に、バッテリ冷却ファンによって車室内の空気を供給してバッテリを冷却する車両用バッテリ冷却システムは、バッテリの温度を検出する第1の温度センサと、車室内の温度を検出する第2の温度センサと、バッテリ冷却ファンの駆動を制御する制御装置と、を備え、制御装置は、車外の外気温度を推定し、車室内の温度と、推定した外気温度と、の差に基づいて、車両の空調装置のブロアファンの出力を推定し、推定した空調装置のブロアファンの出力と、バッテリの温度と、に基づいてバッテリ冷却ファンの出力を制御する。【選択図】図3
