PROBLEM TO BE SOLVED: To control a rechargeable battery mounted in a vehicle.SOLUTION: A vehicular power supply device 1 switches a control for controlling a connection state of a first switch section 11 and a second switch section 12 according to consumption current of an electric load during deceleration of a vehicle, feeding regenerative electric power from an electric generator 6 to a capacitor 5 and feeding electric power to an electric load 4 via a DC converter 14 and a control for feeding the regenerative electric power from the electric generator to the electric load. Accordingly, the regenerative electric power from the electric generator can be properly fed to the capacitor and the electric load during deceleration of the vehicle.SELECTED DRAWING: Figure 2 【課題】車両に搭載された充電式電池を制御する。【解決手段】車両用電源装置１は、車両の減速時に、電気負荷の消費電流に応じて、第１スイッチ部１１と第２スイッチ部１２の接続状態を制御し、発電機６からの回生電力をキャパシタ５へ給電するとともに直流変換器１４を介して電気負荷４へ給電する制御と、発電機からの回生電力を電気負荷へ給電する制御とを切り換える。これにより、車両の減速時に、発電機からの回生電力をキャパシタと電気負荷とへ適切に給電することができる。【選択図】図２
