Abstract
The present disclosure relates to a method for networking a plurality of power battery packs via a CAN bus, each battery pack is provided with an independent BMS. The method includes: waking up the BMS to monitor the CAN bus; transmitting, by the BMS, a network access request to a server if the BMS receives a query packet within a preset first time period; otherwise, transmitting, by the BMS, a control request to other BMSs. The query packet is transmitted by the BMS currently serving as a server for querying a voltage of a battery pack corresponding to other BMSs; transmitting a network access request includes: waiting, by the BMS, for a first random duration, generating a frame ID according to the voltage of the corresponding battery pack, transmitting a data packet for requesting to allocate an ID to the server, and becoming a client after receiving the allocated ID.
