Communication Method and Apparatus for a Wireless Battery Management System

The present disclosure provides a communication method and apparatus for a wireless battery management system. The wireless battery management system comprises one central device and a plurality of peripheral devices. The communication method comprises: the central device and the plurality of peripheral devices form a point-to-multipoint bidirectional communication link; when the bidirectional communication link is a periodic advertising with hierarchical responses link, each periodic advertising interval in the bidirectional communication link comprises a plurality of subevent sets, and the plurality of subevent sets comprise at least two target subevent sets, each target subevent set containing at least one subevent, and each subevent being configured with a plurality of response slots. Among the at least two target subevent sets, response slot spacings of different target subevent sets are different, and/or response slot delays of different target subevent sets are different. The present disclosure can support hierarchical transmission of battery parameters.
