Battery management system, power battery system and vehicle

Abstract

The invention relates to a battery management system, a power battery system and a vehicle. The battery management system comprises a master control module, a high-voltage module and at least two slave control modules, wherein the at least two slave control modules are corresponding to battery modules; the master control module comprises a first wireless communication unit; each slave control module comprises a second wireless communication unit; the high-voltage module comprises a third wireless communication unit; and the master control module, the high-voltage module and each slave controlmodule are in wireless communication connection through the corresponding wireless communication units. According to the battery management system, the power battery system and the vehicle of the invention, the master control module, the high-voltage module and each slave control module are each provided with one wireless communication unit; wireless communication between the master control moduleand the high-voltage module and wireless communication between the master control module and the slave control modules can be achieved; due to the fact that all the modules are connected without wireharnesses, the interlacing of high-voltage harnesses and low-voltage harnesses is avoided, and the arrangement of all the modules is more flexible, and applicability is higher.
