To provide a power source device for an electric vehicle that can prevent increase of cost or limitation on the layout.SOLUTION: The present invention includes: a connection circuit 8 for connecting a plurality of secondary battery modules 3 so that the connection can be changed between a serial connection and a parallel connection; a switch control unit 20 for controlling the switch state of the connection circuit 8; and a rapid charge connector 4, to which a rapid charging charger to charge the secondary battery modules is connected. The switch control unit 20 controls the switch state of the connection circuit 8 to connect the secondary battery modules 3 in parallel when the rapid charging charger is connected to the rapid charge connector 4, and controls the switch state of the connection circuit 8 to connect the secondary battery modules 3 serially when the rapid charging charger is not connected to the rapid charge connector 4.SELECTED DRAWING: Figure 1
【課題】コストアップやレイアウトが制限されてしまうことを防止することができる電動車両の電源装置を提供すること。【解決手段】複数の二次電池モジュール3を直列又は並列に切り替え可能に接続する接続回路8と、接続回路8の切り替え状態を制御する切替制御部20と、複数の二次電池モジュールを充電する急速充電用充電器が接続される急速充電用コネクタ4と、を有し、切替制御部20は、急速充電用充電器が急速充電用コネクタ4に接続された場合には、複数の二次電池モジュール3を並列に接続するように接続回路8の切り替え状態を制御し、急速充電用充電器が急速充電用コネクタ4に接続されていない場合には、複数の二次電池モジュール3を直列に接続するように接続回路8の切り替え状態を制御する。【選択図】図1
