To provide a battery temperature adjustment device for adjusting the temperature of a secondary battery that a battery pack mounted in a vehicle includes, in which a decrease in the electric power supplied to loads other than a heater that are mounted to the vehicle is suppressed.SOLUTION: A battery temperature adjustment device 1 is constituted by comprising: a heat accumulator 3 for exchanging heat between a heater H and a heat medium; a path 4 for connecting the heat accumulator 3 and a battery pack 2 with each other; a battery pack side switching unit 5 for switching the battery pack side opening of the path 4 to an open state or a closed state; a heat accumulator side switching unit 6 for switching the heat accumulator side opening of the path 4 to an open state or a closed state; and a control unit 7. The control unit 7 drives the heater H while a secondary battery B is being charged to accumulate heat in the heat medium and stops the heater H while a vehicle Ve is in operation, as well as places the battery pack side opening and the heat accumulator side opening into an open state so that the temperature of the secondary battery B rises as heat is exchanged between the heat medium and the secondary battery B.SELECTED DRAWING: Figure 1

    【課題】車両に搭載される電池パックが有する二次電池の温度を調整する電池温調装置において、車両に搭載されるヒータ以外の負荷に供給される電力が低減することを抑制する。【解決手段】ヒータHと熱媒体との間で熱交換を行う蓄熱器3と、蓄熱器3と電池パック2とを互いに接続する経路4と、経路4の電池パック側開口部を開状態または閉状態に切り替える電池パック側切替部5と、経路4の蓄熱器側開口部を開状態または閉状態に切り替える蓄熱器側切替部6と、制御部7とを備えて電池温調装置1を構成し、制御部7は、二次電池Bの充電中、ヒータHを駆動させて熱媒体に蓄熱し、車両Veの稼働中、ヒータHを停止させるとともに、熱媒体と二次電池Bとの間で熱交換が行われることで二次電池Bが昇温するように、電池パック側開口部及び蓄熱器側開口部を開状態にさせる。【選択図】図1
