To provide a power supply controller which allows appropriate voltage application to an electric load when a starter is driven.SOLUTION: A BCM 20 which is applied to an on-vehicle power supply system 100 is provided with: a voltage acquisition unit 21 which acquires voltage of a lead storage battery 11; a booster control unit 22 which determines a boosting amount according to the acquired voltage to boost the voltage input in a booster circuit 30 on the basis of the boosting amount; and a restart determination unit 23 which determines that an engine 200 is restarted. The BCM 20 changes the boosting amount which is determined according to the acquired voltage, and boosts the voltage on the basis of the boosting amount after change when it is determined that the engine 200 is restarted.SELECTED DRAWING: Figure 1

    【課題】始動機を駆動させる場合において、電気負荷に適切な電圧印加を可能とする電源制御装置を提供すること。【解決手段】車載電源システム100に適用されるBCM20は、鉛蓄電池11の電圧を取得する電圧取得部21と、取得電圧に応じて昇圧量を決定し、昇圧回路30に入力された電圧を昇圧量に基づき昇圧させる昇圧制御部22と、エンジン200の再始動が行われることを判定する再始動判定部23と、を備える。BCM20は、エンジン200の再始動が行われると判定された場合に、取得電圧に応じて決定される昇圧量を変更し、変更後の昇圧量に基づき昇圧させる。【選択図】 図1
