Document Type and Number:
WIPO Patent Application WO/2023/131036
Kind Code:
A1
Abstract:
The present application relates to a control device for a battery pack active fuse, comprising a battery management system and a shunt resistor. The battery management system comprises a continuously-powered short-circuit current detection circuit and a short-circuit current processing circuit. The shunt resistor and the active fuse are connected in series in a power supply circuit of the battery pack. The short-circuit current detection circuit is connected to the shunt resistor and the short-circuit current processing circuit. The short-circuit current processing circuit is connected to the active fuse. Upon receiving a short-circuit overcurrent signal, the short-circuit current processing circuit controls the active fuse to be disconnected.
