BATTERY MONITORING SYSTEM, BATTERY AND ELECTRIC APPARATUS

WIPO Patent Application WO/2023/115273

A1

The present application relates to the field of batteries (100), and particularly to a battery monitoring system (30), a battery (100), and an electric apparatus (1000). In the battery monitoring system (30), when a main monitoring component (31) is awake, the main monitoring component (31) and N sensing components (32) can jointly detect abnormal situations of all battery cell modules (20) in a battery (100) in an all-around manner. When the main monitoring component (31) is dormant, the N sensing components (32) periodically detect anomalies at a relatively low power consumption. When an anomaly has been detected by any of the sensing components (32), the subsequent sensing components (32) may be successively woken up by means of a serial communication network, and the main monitoring component (31) is then woken up by means of the last sensing component (32) to perform all-around detection and report an anomaly fault. Therefore, when the battery monitoring system (30) is dormant, same can still monitor the safety of the battery (100) in real time at a low power consumption.
