The invention provides a communication fault processing system and method and an automobile, and the system comprises a plurality of sampling modules, every two adjacent sampling modules are electrically connected, and each sampling module is connected with a battery module; the bridging module is electrically connected to the two sampling modules on the outermost side to form a daisy chain communication structure; the processing module is electrically connected to the bridging module; wherein the processing module is used for judging whether the daisy chain communication structure has a communication fault or not based on a communication signal of the sampling module; if the daisy chain communication structure does not have the communication fault, the processing module is used for sending an acquisition instruction to the daisy chain communication structure so as to acquire state parameters of each battery module; and if the daisy chain communication structure has a communication fault, the processing module is also used for resetting the daisy chain communication structure. The method is convenient to operate, can be used for solving the communication fault of the sampling chip in the battery management system, and improves the robustness of the system.

    本发明提供一种通讯故障的处理系统、方法及汽车,包括:多个采样模块,相邻两个采样模块电性连接,每个采样模块连接一个电池模组;桥接模块,电性连接于最外侧两个采样模块,以形成菊花链通讯结构;以及处理模块,电性连接于桥接模块;其中,处理模块用以基于采样模块的通讯信号,判断菊花链通讯结构是否存在通讯故障;若菊花链通讯结构不存在通讯故障,处理模块用以向菊花链通讯结构发送采集指令,以采集每个电池模组的状态参数;若菊花链通讯结构存在通讯故障,处理模块还用以对菊花链通讯结构进行复位处理。本发明操作方便,可用以解决电池管理系统中采样芯片的通讯故障,提高了系统的鲁棒性。
