PROBLEM TO BE SOLVED: To implement charge of an auxiliary battery by using power of a main battery before the auxiliary battery cannot be sufficiently charged because of a temperature fall.SOLUTION: A vehicle charge control device 1 comprises: a main battery 10 which supplies power to a motor for propelling a vehicle; an auxiliary battery 20 which supplies power of a lower voltage than the main battery is converter into a voltage and supplied to the auxiliary battery; a DC/DC converter 30 by which power of the main battery is converted into a voltage and supplied to the auxiliary battery; a control device 40 by which, the DC/DC converter is actuated after a parking time of the vehicle is over a predetermined standby time, and charge of the auxiliary battery is implemented while using power of the main battery; a main battery temperature sensor 50 which detects a temperature of the main battery; and an auxiliary battery temperature sensor 60 which detects a temperature of the auxiliary battery. If it is detected that the temperature of at least one of the main battery and the auxiliary battery is equal to or lower than a predetermined temperature, the control device shortens the standby time.SELECTED DRAWING: Figure 1

    【課題】温度低下により補機バッテリを十分に充電できなくなる前に、主バッテリの電力を用いて補機バッテリの充電を実施する。【解決手段】車両用充電制御装置1は、車両を推進させるモータに電力を供給する主バッテリ10と、主バッテリよりも低圧な電力を車両の補機に供給する補機バッテリ20と、主バッテリの電力を電圧変換して補機バッテリに供給するDC/DCコンバータ30と、車両の駐車時間が所定の待機時間経過すると、DC/DCコンバータを作動させて、主バッテリの電力を用いて補機バッテリの充電を実施する制御装置40と、主バッテリの温度を検出する主バッテリ温度センサ50と、補機バッテリの温度を検出する補機バッテリ温度センサ60とを備える。制御装置は、主バッテリと補機バッテリの少なくとも一方の温度が所定温度以下であると検出されたとき、前記待機時間を短くする。【選択図】図1
