Title:
POWER SUPPLY EQUIPPED WITH BATTERY UNIT
Document Type and Number:
WIPO Patent Application WO/2022/181600
Kind Code:
A1
Abstract:
The present invention blocks a current by reliably fusing a fuse element of an SCP with a simple circuit configuration. This power supply comprising a battery unit performs, with a control circuit 7, ON/OFF control of a switch 6 which connects, to a battery unit 1, an SCP 3 that is connected in series to the battery unit 1 and blocks charge/discharge current in an abnormal state. The battery unit 1 comprises a plurality of battery cells 2 connected in series, wherein: the SCP 3 includes a fuse element 4 connected in series to an output side of the battery unit 1, and a heater 5 for fusing the fuse element 4; the switch 6 comprises a plurality of switching elements 10 formed by connecting one terminal to the heater 5 and the other terminal to a different voltage terminal 11 of the battery unit 1; the control circuit 7 selects, with a selection circuit 9, the switching elements 10 switched to an ON state by a detection voltage of a voltage detection circuit 8; and the ON-state switching elements 10 connect the battery unit 1 to the heater 5 to fuse the fuse element 4.
