To provide a vehicle battery charging control device capable of preventing a time until external charging starts from becoming longer while enabling supplementary charging and external charging.SOLUTION: A supplementary charging device is provided that performs supplementary charging for charging a low-voltage battery with output power of a high-voltage battery. When an external charging start condition is established during implementation of supplementary charging, a command to start external charging is issued to a charger after the supplementary charging device is stopped. When a supplementary charging termination condition is established in a state where the external charging start condition is not established, control after supplementary charging stop for erasing predetermined information held by a control device and updating is performed after the supplementary charging device is stopped. When the supplementary charging termination condition is established along with establishment of the external charging start condition, implementation of the control after supplementary charging stop is restricted.SELECTED DRAWING: Figure 6
【課題】補充電および外部充電を可能としつつ、外部充電が開始するまでの時間が長くなるのを防止できる車両のバッテリ充電制御装置を提供する。【解決手段】高電圧バッテリの出力電力により低電圧バッテリを充電する補充電を実施する補充電装置を設け、補充電の実施中に外部充電開始条件が成立すると、補充電装置が停止された後に充電器に対して指令を外部充電を開始させる出し、外部充電開始条件が成立していない状態で補充電終了条件が成立したときは、補充電装置の停止後に、制御装置が保持している所定の情報を消去し且つ更新する補充電停止後制御を実施し、外部充電開始条件の成立に伴って補充電終了条件が成立したときは、補充電停止後制御の実施を制限する。【選択図】図6
