To provide a battery temperature adjustment device that can reduce power consumption of a battery.SOLUTION: A battery temperature adjustment device 10 cools or heats cooling water using power from a running battery 5 installed in a vehicle and cools by the cooling water or heats the battery 5 to an appropriate temperature to adjust the temperature of the battery 5. If a distance from a current location to a destination of the vehicle is equal to or less than a predetermined distance and the vehicle is parked for a predetermined time after arriving at the destination and is to be driven the next time, the battery temperature adjustment device predicts a temperature change, which is a change in the temperature of the battery 5 in a predetermined period of time, determines a target temperature before the next journey which is a target temperature of the battery 5 for the next journey, within a first temperature range, calculates a pre-parking target temperature of the battery 5, which is a target temperature of the battery before parking, from the temperature change and the target temperature before the next journey, and adjusts the temperature of the battery 5 at the minimum capacity required for the temperature of the battery 5 to be at the pre-parking target temperature when the vehicle arrives at the destination.SELECTED DRAWING: Figure 3
【課題】バッテリの消費電力を低減することができるバッテリ温度調整装置を提供する。【解決手段】車両に搭載される走行用バッテリ5の電力を用いて冷却水を冷却または加熱し、冷却水によってバッテリ5を冷却または適温加熱してバッテリ5の温度を調整するバッテリ温度調整装置10。車両の現在地から目的地までの距離が所定距離以下の場合であって、車両が目的地に到着してから所定時間だけ駐車された後に次回走行する場合には、所定時間におけるバッテリ5の温度の変化である温度変化分を予測し、次回走行する時のバッテリ5の目標の温度である次回走行前目標温度を第1温度範囲以内にて決定し、温度変化分と次回走行前目標温度とからバッテリ5の駐車前の目標温度である駐車前目標温度を算出し、目的地に到着した時にバッテリ5の温度が駐車前目標温度になるために必要な最小能力にてバッテリ5の温度を調整する。【選択図】図3
