The invention provides a power battery pack fault control system and method based on an automobile. The power battery pack fault control system based on the automobile comprises a battery management module, a parameter acquisition module and a VCU, wherein the parameter acquisition module and the VCU are electrically connected with the battery management module; the parameter acquisition module isused for periodically acquiring parameter information of the power battery pack for N times in each period, and N is greater than 1; the battery management module is used for analyzing and processingthe parameter information of the power battery pack in each period and determining whether the power battery pack has a fault or not; the VCU is used for controlling to execute a corresponding instruction according to the fault degree under the condition that a fault occurs; by means of the scheme, whether the power battery pack breaks down or not can be judged, corresponding measures are adoptedfor processing according to the fault degree, and therefore the whole vehicle can be controlled more accurately and effectively.

    本发明提供了一种基于汽车的动力电池包故障控制系统及方法,该基于汽车的动力电池包故障控制系统包括:电池管理模块、以及分别与电池管理模块电连接的参数采集模块、VCU;参数采集模块,用于周期性采集动力电池包的参数信息,且每个周期内采集N次,N大于1;电池管理模块,用于对每个周期内的动力电池包的参数信息进行分析处理,确定动力电池包是否发生故障;VCU,用于在发生故障的情况下,根据故障程度,控制执行对应的指令;通过上述方案,可以对动力电池包是否发生故障进行判断,且根据故障程度采用对应的措施进行处理,使整车的控制更加准确、有效。
