Title:
LOW-VOLTAGE LITHIUM BATTERY CIRCUIT AND PROTECTION METHOD FOR LOW-VOLTAGE LITHIUM BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/082370
Kind Code:
A1
Abstract:
A low-voltage lithium battery circuit and a protection method for a low-voltage lithium battery. The low-voltage lithium battery circuit provides protection when it is detected that electrical parameters in the circuit exceed a range; a lithium battery module (M1) is connected to a battery management system (U1), and the lithium battery module provides energy for an external load and supplies power to the battery management system; and the battery management system supplies power to the external load connected to a positive electrode of a battery system and a negative electrode of the battery system. The low-voltage lithium battery module of the present application can establish bidirectional communication with the whole vehicle to realize intelligent management.
