To provide a battery warming-up device which can improve the efficiency in temperature control of a drive battery mounted to an electric automobile for a commercial car.SOLUTION: A battery warming-up device includes a pump 31 for circulating, in a cooling medium circulation circuit 3, a cooling medium which exchanges heat with a battery 5 that supplies electric power to a motor for driving a vehicle, and a pump control part that controls the temperature of the battery by controlling the pump. The battery is arranged in the vehicle more backward than a cab that is supported by a vehicle forward portion of a ladder frame forming the vehicle, and the pump is arranged near the battery. The pump control part, when the battery is under a condition of being discharged or charged, controls the pump to keep the battery warm by the exhaust heat collected from the battery.SELECTED DRAWING: Figure 1

    【課題】商用車の電気自動車に搭載される駆動用バッテリの温度制御における効率を向上させることができるバッテリ暖機装置を提供する。【解決手段】所定の作動温度範囲を有し、車両を駆動するモータに電力を供給するバッテリ5と熱交換する冷媒を冷媒循環回路3において循環させるポンプ31と、ポンプを制御することにより、バッテリの温度を制御するポンプ制御部と、を含む。バッテリは、車両を構成するラダーフレームの車両前方部分に支持されるキャブより車両の後方に配置され、ポンプは、バッテリの近傍に配置され、ポンプ制御部は、バッテリが、放電、又は充電される条件下にある場合、ポンプを制御し、バッテリから回収された排熱によりバッテリを保温する。【選択図】図1
