PROBLEM TO BE SOLVED: To inhibit a voltage output from a battery of a power supply source for an electric heater from exceeding an upper limit value, thereby protecting the battery.SOLUTION: A battery temperature adjustment device 1 comprises: an electric blower fan 10 that introduces air to a travel drive battery 2 mounted in a vehicle; a PTC heater 11 that is actuated by its being supplied with power by the travel drive battery 2 and heats the air introduced to the travel drive battery 2 by an electric blower fan 10; and a control unit 13 that controls actuating of the PTC heater 11 and electric blower fan 10; The battery temperature adjustment device has a temperature sensor 12 that detects a temperature of a battery cell of the travel drive battery 2. A power supply source for the electric blower fan 10 is a battery 16 for an auxiliary machine. The control unit 13 variably controls a rotational speed of the electric blower fan 10 on the basis of the temperature of the travel drive battery 2.SELECTED DRAWING: Figure 1
【課題】電気ヒータの電力供給源の電池の出力電圧が上限値を超えることを抑制し、当該電池の保護を図る。【解決手段】車両に搭載された走行駆動用電池2に空気を導く電動ブロアファン10と、走行駆動用電池2から電力を供給されて作動し電動ブロアファン10によって走行駆動用電池2に導かれる空気を加熱するPTCヒータ11と、PTCヒータ11及び電動ブロアファン10の作動制御をするコントロールユニット13と、を備えた電池温調装置1であって、走行駆動用電池2の電池セルの温度を検出する温度センサ12を有し、電動ブロアファン10の電力供給源は車両に搭載された補機用電池16であり、コントロールユニット13は走行駆動用電池2の温度に基づいて、電動ブロアファン10の回転速度を可変制御する。【選択図】図1
