To provide a battery cooling controller for an electric vehicle that can sufficiently cool a battery during a travel up to a destination without any hindrance to the vehicle travel by making the most of the limited capacity of the battery, and thus can suppress deterioration of the battery being left as it is at a high temperature.SOLUTION: Before a vehicle 1 starts traveling, the remaining amount of electric power of a high-voltage battery 8 when a destination is reached is predicted by a vehicle ECU 25, and cooling usable electric power is calculated which can be used to cool the high-voltage battery 8 by a battery cooling device 11 on the basis of the remaining amount of electric power (S2). Once the vehicle 1 starts traveling (Yes at S3), the cooling usable electric power is updated at intervals of a time T (S4, S7), and an operation point for the most efficient operation of the battery cooling device 11 is also set for the cooling usable electric power at the point of time so as to control electric power supply to the battery cooling device 11 by an air-conditioner ECU 24 so that the battery cooling device 11 operates at the operation point.SELECTED DRAWING: Figure 2

    【課題】限りあるバッテリの容量を最大限に活用して、車両走行に支障を及ぼすことなく目的地に到達するまでの走行中にバッテリを十分に冷却でき、これにより高温で放置されたときのバッテリの劣化を抑制できる電動車両のバッテリ冷却制御装置を提供する。【解決手段】車両1の走行開始前に、目的地に到達したときの高電圧バッテリ8の残電力量を車両ECU25により予測し、残電力量に基づきバッテリ冷却装置11による高電圧バッテリ8の冷却のために使用可能な冷却使用可能電力を算出する(S2)。車両1の走行が開始されると(S3がYes)、インターバル時間T毎に冷却使用可能電力を更新する一方(S4,7)、その時点の冷却使用可能電力に対して最も良好な効率でバッテリ冷却装置11が作動する作動ポイントを設定し、その作動ポイントでバッテリ冷却装置11が作動するように、エアコンECU24によりバッテリ冷却装置11への電力供給を制御する。【選択図】図2
