To provide a battery temperature adjustment system capable of appropriately suppressing the deterioration of a battery.SOLUTION: A battery temperature adjustment system 1 includes: a battery 2 which can store electric power with electric power from an external power source 10 and supplies the electric power to a motor 7; a cooling device 3 which is selectively supplied with the electric power from the external power source 10 and the electric power from the battery 2, and cools the battery 2; and a control device 5 which controls the cooling device 3 to adjust the state of charge of the battery 2 and a battery temperature. The control device 5 stores a deterioration sensitivity map in which a deterioration sensitivity is preset according to the state of charge and the battery temperature, or can calculate a deterioration sensitivity according to the state of charge and the battery temperature. When a vehicle V is connected to the external power source, the control device 5 selects either one of the electric power from the battery 2 and the electric power from the external power source 10 on the basis of the deterioration sensitivity to operate the cooling device 3.SELECTED DRAWING: Figure 5

    【課題】バッテリの劣化を適切に抑制可能なバッテリ温調システムを提供する。【解決手段】バッテリ温調システム1は、外部電源10からの電力により蓄電可能であり、モータ7に電力を供給するバッテリ2と、外部電源10からの電力及びバッテリ2からの電力が選択的に供給され、バッテリ2を冷却する冷却装置3と、冷却装置3を制御してバッテリ2の充電状態及びバッテリ温度を調整する制御装置5と、を備える。制御装置5は、充電状態及びバッテリ温度に応じて劣化感度が予め設定された劣化感度マップを記憶しており、又は、充電状態及びバッテリ温度に応じて劣化感度を算出可能である。制御装置5は、車両Vが外部電源に接続されているとき、劣化感度に基づいて、バッテリ2からの電力及び外部電源10からの電力のいずれか一方を選択し、冷却装置3を作動する。【選択図】図5
