The invention belongs to the technical field of new energy electric vehicles and the field of data communication, and discloses a BMS wireless networking system and method for pure electric passenger vehicles. The BMS wireless networking system comprises a main control unit and a plurality of acquisition units, the main control unit is connected with the plurality of acquisition units by adopting a Mesh wireless ad hoc network technology; the number of the acquisition units is in one-to-one correspondence with the number of battery modules of the pure electric passenger vehicle. The BMS wireless networking method comprises the step of establishing connection between the main control unit and the plurality of acquisition units by adopting a Mesh wireless ad hoc network technology. According to the technical scheme, the purposes of reducing low-voltage wire harnesses and interconnection plug-ins and improving the expandability of the battery system are achieved, so that the battery module is easier to disassemble and replace and more convenient to install and maintain, and meanwhile, the possibility that the plug-ins are loosened or the wire harnesses are short-circuited and open-circuited due to vibration in the driving process is avoided.

    本发明属于新能源电动汽车技术领域和数据通信领域,公开了一种用于纯电动乘用车的BMS无线组网系统及方法。BMS无线组网系统包括:主控单元和多个采集单元;所述主控单元与多个所述采集单元之间采用Mesh无线自组网技术连接;多个所述采集单元与所述纯电动乘用车的电池模组数量一一对应。BMS无线组网方法包括:采用Mesh无线自组网技术,建立主控单元和多个所述采集单元之间的连接。通过上述技术方案,达到了减少低压线束及互连接插件,提高电池系统可扩展性的目的,从而使得电池模组拆换更加容易,安装及维修更加方便,同时避免了行车过程中由于震动导致接插件松动或者发生线束短路和断路的可能性。
