To suppress an overcharge or run-out of an auxiliary-machine battery.SOLUTION: An HV ECU 24 of an auxiliary-machine system 22 acquires a power consumption of the auxiliary-machine system 22. A solar ECU 16 controls an electric power supply rate to a driving battery 18 and the auxiliary-machine system 22 so that an electric power supply amount to the auxiliary-machine system 22 becomes larger as compared with the case where the power consumption of the auxiliary-machine system 22 is less than a prescribed value when the power consumption of the auxiliary-machine system 22 acquired by the HV ECU 24 is a prescribed value or larger in a first electric power supply mode that supplies a power to the driving battery 18 and the auxiliary-machine system 22.SELECTED DRAWING: Figure 1
【課題】補機バッテリが過充電になったり上がってしまうことを抑制する。【解決手段】補機系統22のHV ECU24は、補機系統22の消費電力を取得する。ソーラーECU16は、駆動用バッテリ18および補機系統22へ電力を供給する第1の給電モードにおいて、HV ECU24によって取得された補機系統22の消費電力が所定値以上の場合に、補機系統22の消費電力が所定値未満の場合に比べて補機系統22への給電量が大きくなるように、駆動用バッテリ18および補機系統22への給電割合を制御する。【選択図】図1
