To execute charging of a battery with high power without generating an over current state in the battery also when executing a temperature adjustment of the battery and the charging of the battery at the same time.SOLUTION: An on-vehicle charger 30 that performs power conversion of electric power supplied from an external power supply S in a charging circuit 31 and supplies the electric power to a battery 41 and a battery temperature adjustment device 43 in parallel, comprises a control device 32 that controls an output current of the charging circuit 31 so as to be close to a total of an allowance of the charging current of the battery 41 at each point of time during the execution of the charging and a consumption current of the battery temperature adjustment device 43 when executing a temperature adjustment of the battery 41 and the charging of the battery 41 by the battery temperature adjustment device 43 at the same time. The allowance of the charging current of the battery 41 and the consumption current of the battery temperature adjustment device 43 are specified on the basis of prestored battery characteristic information of the battery 41 and heater characteristic information of the battery temperature adjustment device 43.SELECTED DRAWING: Figure 2
【課題】バッテリの温度調整とバッテリの充電を同時に実行する際にも、バッテリに対して過電流状態を発生させることなく、バッテリに対する充電を大電力で実行することを可能とする。【解決手段】充電回路31にて外部電源Sから供給される電力を電力変換して、バッテリ41及びバッテリ温調装置43に対して並列に電力供給する車載充電装置30において、バッテリ温調装置43によるバッテリ41の温度調整とバッテリ41の充電を同時に実行する際、充電実行中の各時点におけるバッテリ41の充電電流の許容値及びバッテリ温調装置43の消費電流の合計値に近づけるように、充電回路31の出力電流を制御する制御装置32を備える。バッテリ31の充電電流の許容値及びバッテリ温調装置43の消費電流は、予め記憶されたバッテリ31のバッテリ特性情報及びバッテリ温調装置43のヒータ特性情報に基づいて特定される。【選択図】図2
