Further, the master battery device and the slave battery devices in the battery pack have corresponding BMS codes, and the BMS codes, as unique identifiers of the battery devices in the battery pack, may exist together with the battery devices in the form of bar codes, that is, each battery device has its corresponding BMS code, and the BMS codes are generated correspondingly for each battery device through a preset encoder, and the bar codes may be generated according to the current time or through a random number mechanism of the encoder.
Furthermore, the master battery device and the slave battery devices included in the battery pack in the BMS battery management system are connected through the CAN bus, and when the dynamic address allocation is started for the battery devices in the BMS battery management system, each battery device sends its corresponding BMS code to all the battery devices except the battery device in a broadcast manner, and meanwhile, each battery device as the current battery device also receives the BMS codes sent by all the battery devices except the battery device in a broadcast manner.
