POWER SUPPLY SYSTEM AND POWER SUPPLY BACKUP CIRCUIT UNIT
Document Type and Number:
WIPO Patent Application WO/2018/193976
Kind Code:
A1
Abstract:
A power supply system is provided with: a power supply (4) including at least a storage battery (battery 8) and feeding power to a plurality of loads (14-1, 14-2, 14-3); an electricity storage element (20) installed separately from the storage battery; a control means (control unit 30, ECU 38) for controlling a single or a plurality of loads to which the power is fed from the power supply; and a power supply backup circuit (6) that charges the electricity storage element by using the power supply, is connected to any or all of the loads, and receives a control signal from the control means, thereby backing up the power feeding to the loads by using the electricity storage element before or when the voltage of the power supply is lost or dropped. This eliminates a DC-DC converter and makes it possible to back up the power supply.
