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: When a supplementary charging termination condition is established, information erasure control and update control are carried out. When the supplementary charging termination condition is established in a state where an external charging start condition is not established, after the elapse of a predetermined reference time from the end of the information erasure control, SOC reception control for performing CAN communication with a SOC calculation device and receiving information on a battery SOC from the SOC calculation device is carried out. When the supplementary charging termination condition is established along with establishment of the external charging start condition, external charging start control is started after execution of stop control and before the elapse of the reference time from the end of the information erasure control.SELECTED DRAWING: Figure 10
【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】補充電終了条件が成立すると情報消去制御と更新制御とを実施し、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、情報消去制御が終了してから所定の基準時間が経過した後に、SOC算出装置とCAN通信して当該SOC算出装置からバッテリSOCの情報を受け取るSOC受け取り制御を実施し、外部充電開始条件の成立に伴って前記補充電終了条件が成立したときは、停止制御の実施後且つ情報消去制御が終了してから基準時間が経過する前に外部充電開始制御を開始する。【選択図】図10
