To provide a battery temperature control device for an electric vehicle that is able to efficiently increase the temperature of a battery for vehicle drive while executing V2G in a low temperature environment.SOLUTION: In a battery temperature control device for an electric vehicle for controlling a temperature of a battery 21 for driving a vehicle mounted in an electric vehicle 3 participating in a V2G, the V2G being capable of bi-directionally transferring electric power between the battery 21 of the electric vehicle 3 and a power system 2, an aggregator 7 on the power system 2 side transmits a charge/discharge start command for the battery 21 to an ECU 20. Thereby, when a battery temperature TB is lower than a predetermined temperature TBREF in a case where the execution of the V2G is started, the ECU 20 controls a four-way valve 54 to thereby couple a battery cooling circuit 50 and a charger cooling circuit 60.SELECTED DRAWING: Figure 1

    【課題】低温環境下において、V2Gを実行しながら、車両駆動用のバッテリを効率よく加温することができる電動車両のバッテリ温度制御装置を提供する。【解決手段】電動車両3に搭載された車両駆動用のバッテリ21と電力系統2との間で双方向の電力の授受が可能なV2Gにおいて、V2Gに参加している電動車両3のバッテリ21の温度を制御するための電動車両のバッテリ温度制御装置であって、電力系統2側のアグリゲータ7がバッテリ21の充放電の開始指令をECU20に送信することにより、V2Gの実行を開始した場合において、ECU20は、バッテリ温度TBが所定温度TBREFよりも低いときに、四方弁54を制御することにより、バッテリ冷却回路50と充電器冷却回路60とを連結する。【選択図】図1
