The invention discloses a fault processing method and device based on a battery management system of a pure electric vehicle, and belongs to the technical field of vehicle fault management. The method comprises the steps: after a certain target fault is monitored, detecting the authenticity of the target fault, and if the method determines that the target fault occurs, reporting a fault code corresponding to the target fault; and determining the fault level of the reported fault code, determining the fault type corresponding to the fault level, and adopting a fault processing mechanism corresponding to the fault type, wherein the higher the fault level is, the more serious the fault type corresponding to the fault level is, and the faster the response time is. Through the more subdivided fault levels and the processing mode thereof, a large number of fault codes can be classified and processed in a modularized mode, and the driving personal safety is improved.

    本发明公开了一种基于纯电动汽车电池管理系统的故障处理方法及装置,属于车辆故障管理技术领域,其中,方法的实现包括:当监测到某一个目标故障后,检测目标故障的真实性,若确定发生目标故障,则上报目标故障对应的故障码;确定上报的故障码的故障等级,确定故障等级对应的故障类型,采用与故障类型对应的故障处理机制,其中,故障等级越高,故障等级对应的故障类型越严重,响应时间越快。通过本发明更加细分的故障等级及其处理方式,有利于模块化对大量故障码进行分类处理,提高行车人身安全。
