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.

    本发明涉及一种电池管理系统、动力电池系统和车辆,该电池管理系统包括主控模块、高压模块和至少两个与各电池模块对应的从控模块,主控模块包括第一无线通讯单元,各从控模块包括第二无线通讯单元,高压模块包括第三无线通讯单元,主控模块、高压模块和各从控模块通过对应的无线通讯单元实现无线通讯连接。本发明通过在主控模块、高压模块和各从控模块上分别设置一个无线通讯单元,可以实现主控模块和高压模块之间以及主控模块和各从控模块之间的无线通讯,由于各模块相互之间无线束连接,不仅避免了高低压线束之间的交错,且各模块的布置更加灵活,适用性更强。
