Application: Battery pack active fuse control apparatus (Patent ID: US20240213765A1)
The patent filed by Contemporary Amperex Technology Ltd. describes a battery pack active fuse control apparatus that includes a battery management system with a short-circuit current detect circuit and a short-circuit current process circuit, along with a shunt resistor and an active fuse connected in series with the power supply loop of a battery pack. The short-circuit current detect circuit samples the current flowing through the shunt resistor to detect when the shunt current exceeds a set threshold, triggering the short-circuit current process circuit to control the active fuse to break in case of a short-circuit overcurrent signal.
Furthermore, the battery management system includes additional components such as a power supply chip module and a digital signal detect module, which are integrated into the short-circuit current process circuit to enhance functionality. The apparatus is designed with specific configurations for the short-circuit current detect circuit and the short-circuit current process circuit, including various resistors, capacitors, and diodes, to ensure efficient operation and accurate detection of short-circuit faults. Additionally, the patent outlines the adjustability of the apparatus to match different high-voltage battery systems with varying short-circuit withstanding capabilities, providing a versatile solution for managing overcurrent faults in battery packs.
