PROBLEM TO BE SOLVED: To perform appropriate charge control to power storage means.SOLUTION: A vehicular power supply system (10) has: a plurality of power storage means (110, 120); power storage amount detection means (310, 320) for detecting a total power storage amount of the plurality of power storage means and individual power storage amounts of each of the power storage means included in the plurality of power storage means, respectively; first charge control means (410) for controlling so as to perform forced charge to the plurality of power storage means when the total power storage amount becomes less than a first threshold; and charge control means (420) for controlling so as to perform charge among the plurality of power storage means when the total power storage amount becomes the first threshold or more and at least one of the individual power storage amounts becomes less than the second threshold.
【課題】蓄電手段に対する適切な充電制御を実行する。【解決手段】車両用電源システム(10)は、複数の蓄電手段(110,120)と、複数の蓄電手段の合計蓄電量、及び複数の蓄電手段に含まれる各蓄電手段の個別蓄電量を夫々検出する蓄電量検出手段(310,320)と、合計蓄電量が第1閾値未満となった場合に、複数の蓄電手段に対し強制充電を実行するよう制御する第1充電制御手段(410)と、合計蓄電量が第1閾値以上であり、個別蓄電量のうち少なくとも1つが第2閾値未満となった場合に、複数の蓄電手段において蓄電手段間充電を実行するよう制御する充電制御手段(420)とを備える。【選択図】図1
