To provide a battery warming system that reduces heat loss generated by a rear-wheel drive device located at the rear of the vehicle and improves electricity consumption, among other benefits.SOLUTION: A battery warming system comprises: a rear wheel drive device 2 which has at least a motor transmitting driving rotational force to a travel system of a vehicle and a housing storing the motor and is arranged at the rear of a battery 3 supplying electric power to the motor; and a warming mechanism which transmits at least waste heat of the motor to the battery 3. The warming mechanism has a pump 53 which pumps cooling liquid distributed through the rear wheel drive device 2 and the battery 3 and valves 55 and 56 which are capable of creating a first state to circulate the cooling liquid through the rear wheel drive device 2 and the battery 3. The pump 53 and the valves 55 and 56 are arranged between the battery 3 and the rear wheel drive device 2.SELECTED DRAWING: Figure 2

    【課題】車両の後側に配置された後輪駆動装置で発生した熱の損失を低減することができ、電費等の向上を図ったバッテリ暖機システムを提供する。【解決手段】駆動回転力を車両の走行系に伝えるモータと当該モータを収容するハウジングとを少なくとも含み、モータに電力を供給するバッテリ3よりも後側に配置された後輪駆動装置2と、少なくともモータの廃熱をバッテリ3に伝達する暖機機構と、を備え、暖機機構は、後輪駆動装置2及びバッテリ3に流通させる冷却流体を圧送するポンプ53と、後輪駆動装置2とバッテリ3とに冷却流体を循環させる第一状態を作り出すことが可能な弁55,56とを有しており、ポンプ53及び弁55,56は、バッテリ3と後輪駆動装置2との間に配置されているバッテリ暖機システム。【選択図】図2
