PROBLEM TO BE SOLVED: To provide a power supply controller that secures an amount of energy charged to a capacitor, preventing a fuel consumption increase even when occasions of decelerated traveling decrease.SOLUTION: A power supply controller includes: a capacitor 2 into which a generated power supplied from an alternator is charged; a DC voltage conversion section 3 that subjects output voltages from the alternator and capacitor to voltage conversion to be supplied to a load group 9 or a lead battery 8; a first control section 4 that controls a charge operation of the capacitor on the basis of a power generation operation of the alternator; and a second control section 7 that controls an operation of the DC voltage conversion section. The first control section 4 includes a determination section that outputs a determination signal Y if the decrease of occasions of regenerative operations is determined. The second control section 7 includes threshold voltage reset means that increases a discharge threshold voltage of the capacitor from an initial set value on the basis of input of the determination signal.

    【課題】減速走行の機会が減少しても、キャパシタへの充電エネルギー量を確保して、燃料消費量の増大を防止し得る電源制御装置を提供する。【解決手段】オルタネータから供給される発電電力を充電するキャパシタ2と、オルタネータ及び前記キャパシタの出力電圧を電圧変換して負荷群9若しくは鉛電池8に供給する直流電圧変換部3と、オルタネータの発電動作に基づくキャパシタの充電動作を制御する第一の制御部4と、直流電圧変換部の動作を制御する第二の制御部7とを備えた電源制御装置において、第一の制御部4には、回生動作機会の減少を判定したとき判定信号Yを出力する判定部を備え、第二の制御部7には判定信号の入力に基づいて、キャパシタの放電しきい値電圧を初期設定値から引き上げるしきい値電圧再設定手段を備えた。【選択図】図1
