To provide a vehicular power supply device capable of accommodating to a future change of a standard of an external charger without using a device unnecessary for compliance of an existing standard.SOLUTION: A vehicular power supply device 10 includes a plurality of battery packs 11, a junction box 12, a power receiving port 13 and a controller 14. An external charger 1 conforming to an existing quick charging standard is connected with the power receiving port 13 and the plurality of battery packs 11 are charged. A maximum voltage Vmax chargeable in a state that all of the plurality of battery packs 11 are connected in series using the junction box 12 is a voltage equal to or higher than a voltage Vh of a higher side among predetermined voltages normalized by a standard of a next generation and thereafter. When the external charger 1 is connected with the power receiving port 13, the controller 14 switches connection between the plurality of battery packs 11 by the junction box 12 and performs control processing of approximating a rechargeable voltage to a maximum voltage Vm that the external charger 1 can supply.SELECTED DRAWING: Figure 1

    【課題】既存の規格の準拠に不必要な装置を利用せずに、外部充電器の将来的な規格の変更に対応することが可能な車両用の電源装置を提供する。【解決手段】複数のバッテリパック11とジャンクションボックス12と受電口13と制御装置14と、を備え、受電口13に既存の急速充電規格を準拠した外部充電器1が接続されて複数のバッテリパック11が充電される車両用の電源装置10において、ジャンクションボックス12により複数のバッテリパック11の全てが直列に接続された状態での充電可能な最大電圧Vmaxは、次世代以降の規格により規格化される予定の電圧のうちでより高い側の電圧Vh以上の電圧であり、制御装置14は、受電口13に外部充電器1が接続された場合に、ジャンクションボックス12により複数のバッテリパック11どうしの接続を切り替えて、充電可能な電圧を外部充電器1の給電可能な最大電圧Vmに近づける制御処理を実行する。【選択図】図1
