The invention is suitable for the technical field of battery management, and provides a communication method of a BMS system. The BMS system comprises a plurality of BMU modules and a BCU module which are sequentially connected end to end, each BMU module is correspondingly provided with a battery data acquisition module, each battery data acquisition module comprises a first level conversion unit, a plurality of AFE units and a second level conversion unit which are sequentially connected, and each BMU module is connected with the corresponding first level conversion unit and the corresponding second level conversion unit; the communication method comprises the steps that a request command data frame integrated with a first BMU module serves as a battery data frame and is sent to a next BMU module, each BMU module integrates battery state data of the BMU module into the battery data frame after receiving the battery data frame, and the battery data frame is sent to the next BMU module; and the last BMU module sends the battery state data frame to the BCU module. According to the method, the communication stability can be improved.

    本申请适用于电池管理技术领域,提供了一种BMS系统的通信方法。该BMS系统包括依次首尾相连的多个BMU模块和BCU模块,BMU模块还对应设置有电池数据采集模块,电池数据采集模块包括依次连接的第一电平转换单元、多个AFE单元、第二电平转换单元,BMU模块分别与对应的第一电平转换单元和第二电平转换单元连接;通信方法包括:将整合了第一个BMU模块的请求命令数据帧作为电池数据帧发送给下一个BMU模块,每个BMU模块接收到电池数据帧后将自身的电池状态数据整合到电池数据帧中,并将电池数据帧发送给下一个BMU模块,直到最后一个BMU模块将电池状态数据帧发送给BCU模块。本申请的方法能够提高通信稳定性。
