Title:
VEHICLE BATTERY ELECTRICAL PROTECTION SYSTEM AND METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/087460
Kind Code:
A1
Abstract:
A vehicle battery electrical protection system, comprising a liquid cooling loop (1), wherein the liquid cooling loop (1) is configured to be in contact with a battery module (7) and a battery disconnect unit (6), and when a water pump (2) operates, a cooling liquid in the liquid cooling loop (1) sequentially passes through the battery module (7) and the battery disconnect unit (6); a temperature sensor (3), configured to acquire the temperature of the battery disconnect unit (6); a current sensor (4), configured to detect the total current of a high-voltage loop where the battery disconnect unit (6) is located; and a battery management system (5), connected to the temperature sensor (3), the current sensor (4), and the water pump (2), respectively, wherein the battery management system (5) is configured to control the operation of the water pump (2) according to the temperature of the battery disconnect unit (6) and the total current of the high-voltage loop where the battery disconnect unit (6) is located, so as to drive the cooling liquid in the liquid cooling loop (1) to dissipate heat from the battery disconnect unit (6), thereby achieving heat dissipation protection of the battery disconnect unit (6). Moreover, the heat dissipation structure of the battery disconnect unit (6) and the battery module (7) is of a series structure, and compared with a parallel structure, the series heat dissipation structure not only has a simple structure and rapid heat dissipation, but also has better fluidity. Also provided are a vehicle battery electrical protection method, an electronic device for implementing the vehicle battery electrical protection method, and a storage medium storing the vehicle battery electrical protection method.
