The invention discloses a power battery fault diagnosis method and system and a computer readable storage medium. The method comprises the steps that the current value of each monitoring index detected by a battery control system of a vehicle is acquired; predicting the current state of the power battery of the vehicle according to the correlation between the current value and the historical value of the monitoring index; and when the state of the power battery is a fault state, determining a fault type based on the current value. Whether the power battery breaks down or not is monitored in real time in the vehicle running process, and when it is predicted that the power battery possibly breaks down, the fault type of the power battery is determined, so that a corresponding fault processing strategy is determined as soon as possible, and the driving safety is improved.

    本发明公开了动力电池故障的诊断方法、系统及计算机可读存储介质,该方法包括:获取车辆的电池控制系统检测到的各个监测指标的当前值;根据所述当前值与所述监测指标的历史值之间的相关性,预测所述车辆当前的动力电池状态;当所述动力电池状态为故障状态时,基于所述当前值确定故障类型。得在车辆运行过程中实时监测动力电池是否发生故障,并在预测动力电池可能出现故障时,确定动力电池的故障类型,以便尽快的确定相应的故障处理策略,提高驾驶安全性。
