Charging fault detection method and device and computer readable storage medium

The invention discloses a charging fault detection method and device and a computer readable storage medium. The charging fault detection method comprises the steps of determining a current working state when a charging fault occurs; and acquiring a charging parameter corresponding to the current working state, and if the charging parameter is abnormal, determining a fault reason according to the abnormal charging parameter. The technical problem that fault detection is difficult when an electric vehicle is charged through an alternating current charging gun at present can be solved. 本发明公开了一种充电故障检测方法、装置及计算机可读存储介质，所述充电故障检测方法包括：确定充电故障时的当前工作状态；获取所述当前工作状态对应的充电参数，若所述充电参数异常，则根据异常充电参数确定故障原因。本发明能够解决目前电动汽车使用交流充电枪充电时，故障检测困难的技术问题。
