PROBLEM TO BE SOLVED: To suppress termination of battery charging of high voltage battery by a battery charger with electric power from an external power supply before completion thereof (before power accumulation ratio reaches a target ratio) in a case where electric power from the external power supply is comparatively small.SOLUTION: In a case where external battery charging is carried out, the external battery charging is terminated when power accumulation ratio of a high voltage battery reaches a target ratio, and when battery charging electric power of the high voltage battery is equivalent to a threshold or less before the power accumulation ratio of the high voltage battery reaches the target. In a system where the external battery charging is terminated in such way, under a low electric power battery charging mode (S100), it is prohibited to drive temperature rising heater for the high voltage battery (S110). Thereby, it may be suppressed that the battery charging electric power of the high voltage battery reduces to predetermined electric power or less, and it may be suppressed that the external battery charging is terminated before completion thereof.SELECTED DRAWING: Figure 2
【課題】外部電源からの電力が比較的小さいときに、外部電源からの電力を用いた充電器による高電圧バッテリの充電が途中で(蓄電割合が目標割合に至る前に)終了するのを抑制する。【解決手段】外部充電を行なっているときには、高電圧バッテリの蓄電割合が目標割合に至ったとき、および、高電圧バッテリの蓄電割合が目標に至る前で且つ高電圧バッテリの充電電力が閾値以下のときに、外部充電を終了する。このように外部充電を終了するものにおいて、低電力充電モードのときには(S100)、高電圧バッテリの昇温用のヒータの駆動を禁止する(S110)。これにより、高電圧バッテリの充電電力が所定電力以下になるのを抑制することができ、外部充電が途中で終了するのを抑制することができる。【選択図】図2
