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 in a state where supplementary charging is not being performed, external charging start control is started after a first time has elapsed since the external charging start condition is satisfied. When the external charging start condition is established during implementation of supplementary charging, stop control for stopping the supplementary charging device, information erasing control for erasing multiple pieces of information, and update control for updating at least part of the erased information are carried out, and the external charging start control is started after a second time longer than the first time has elapsed since the external charging start condition is established.SELECTED DRAWING: Figure 11
【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、補充電が実施されていない状態で外部充電開始条件が成立したときは、外部充電開始条件が成立してから第1時間経過後に外部充電開始制御を開始し、補充電の実施中に外部充電開始条件が成立したときは、補充電装置を停止する停止制御と、複数の情報を消去する情報消去制御と、消去した情報の少なくとも一部を更新する更新制御とを実施するとともに、外部充電開始条件が成立してから第1時間よりも長い第2時間が経過した後に外部充電開始制御を開始する。【選択図】図11
