Title:
POWER SUPPLY SYSTEM AND ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/264485
Kind Code:
A1
Abstract:
A microcomputer of this power supply system controls a switch unit so as to start an on-operation for supplying DC power from a sub-power supply device to a load when the DC power supplied from a main power supply device reduces and a voltage input to the load becomes less than a predetermined threshold value. When the DC power supplied from the main power supply device is restored, the microcomputer starts an off-operation for limiting the DC power supplied from the sub-power supply device to the load, limits the supply of the DC power from the sub-power supply device to the load so that the voltage input to the load does not become less than the predetermined threshold value from the start of the off-operation until a predetermined time has elapsed, and controls the switch unit so that the supply of the DC power from the sub-power supply device to the load becomes zero after the predetermined time has elapsed.
