| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a vehicle power supply device for realizing power output from a battery of an own vehicle to outside via a booster cable without fusion cutting of a battery fuse upon connecting one end of the booster cable to a relief terminal connected to the battery of the vehicle.SOLUTION: A vehicle power supply device including a battery, a relief terminal connected to the battery, and a battery fuse provided on a line connecting the battery to the relief terminal, comprises: switching means connected to the battery fuse in parallel; detection means for detecting detachment of a cover that is detached when the relief terminal is used; and switch-on means for turning on the switching means so as to cause a short-circuit between both ends of the battery fuse if the detection means detects detachment of the cover.
【課題】本発明は、車両用電源装置に係り、自車両のバッテリからブースタケーブルを介した外部への電力出力を、ブースタケーブルの一端を自車両のバッテリに接続する救援端子に接続させたうえで、バッテリヒューズを溶断させることなく実現することにある。【解決手段】バッテリと、バッテリに接続される救援端子と、バッテリと救援端子とを繋ぐライン上に設けられるバッテリヒューズと、を備える車両用電源装置は、バッテリヒューズに並列に接続されるスイッチング手段と、救援端子の使用時に取り外されるカバーの取り外しを検知する検知手段と、検知手段によりカバーの取り外しが検知される場合に、バッテリヒューズの両端が短絡されるようにスイッチング手段をオンするスイッチオン手段と、を備える。【選択図】図１ |
