The invention relates to the field of pure electric vehicle charging, and provides a pure electric vehicle charging fault diagnosis method and a device thereof. The method comprises the steps of: obtaining battery charging state data, vehicle-mounted charger state data and charging pile state data; processing and comparing the charging pile state data with a first preset value, processing and comparing the vehicle-mounted charger state data with a second preset value, processing and comparing the battery charging state data with a third preset value, and displaying first abnormal fault information and/or second abnormal fault information and/or third abnormal fault information; and triggering to cut off the emergency switch if the first abnormal fault information or the second abnormal fault information or the third abnormal fault information occurs, and switching off a pure electric vehicle charging loop. The acquired state data is compared with the set value, abnormal fault information is prompted, and the emergency switch is cut off, so that the charging safety of the pure electric vehicle in a family is improved, the fault position can be conveniently obtained, unnecessary panic misoperation is reduced, and the electric shock risk is reduced.
本发明涉及纯电动汽车充电领域,提供一种纯电动汽车充电故障诊断方法与装置,包括获取电池充电状态数据和车载充电机状态数据和充电桩状态数据;处理充电桩状态数据与第一预定值比较,处理车载充电机状态数据与第二预定值比较,处理电池充电状态数据与第三预定值比较,显示第一异常故障信息和/或第二异常故障信息和/或第三异常故障信息;若出现第一异常故障信息或第二异常故障信息或第三异常故障信息,触发执行切断应急开关,断开纯电动汽车充电回路。通过获取状态数据与设定值比较处理,提示异常故障信息且切断应急开关,不仅提高纯电动汽车在家庭中充电的安全性,而且能够方便地获知故障位置,减少不必要的恐慌性误操作,减少触电风险。
