PROBLEM TO BE SOLVED: To suppress degradation of a battery in a vehicle on which a high-load instrument and a backup target instrument are mounted.SOLUTION: An electric power supply device (100, 200) includes: a first battery and a second battery (12, 13) each of which supplies electric power to a plurality of load instruments mounted on a vehicle; an electric power generator (11) which can charge the first battery and the second battery by regenerative electric power generation; and control means (14) which controls the electric power generator in such a way that electric energy of at least one of the first battery and the second battery charged by regenerative electric power generation is suppressed in a case where at least one of a high-load instrument and a backup target instrument are present among the plurality of load instruments, and the electric power generator performs regenerative electric power generation during the deceleration of the vehicle.SELECTED DRAWING: Figure 2
【課題】大負荷機器、バックアップ対象機器が搭載されている車両においてバッテリの劣化を抑制する。【解決手段】電源装置(100、200)は、車両に搭載された複数の負荷機器に対して夫々電力を供給する第1バッテリ及び第2バッテリ(12、13)と、回生発電により第1バッテリ及び第2バッテリを充電可能な発電機(11)と、複数の負荷機器のなかに高負荷機器及びバックアップ対象機器の少なくとも一方が存在し、且つ車両の減速時に発電機が回生発電を行っている場合、回生発電による第1バッテリ及び第2バッテリの少なくとも一方の充電電力量が抑制されるように、発電機を制御する制御手段(14)と、を備える。【選択図】図2
