Electric power supply device

摘要

ELECTRIC POWER SUPPLY DEVICE An electric power supply device (100) includes first and second batteries (12, 13) respectively supplying electric power to a plurality of load instruments mounted on a vehicle, an electric power generator (11) capable of charging the first battery and the second battery by regenerative electric power generation, and control means (ECU) for controlling the electric power generator so that a charging electric power amount of at least one of the first battery and the second battery based on the regenerative electric power generation is suppressed in a case where at least one of a high-load instrument and a backup target instrument is present among the plurality of load instruments and the electric power generator is performing the regenerative electric power generation during the deceleration of the vehicle.
