The invention discloses an electric vehicle charging fault intelligent diagnosis system and a method. The diagnosis system comprises an information acquisition module, a fault judgment module and a fault processing module, wherein the information acquisition module is used for acquiring fault codes, on-off state information and operation state information of a power battery, a charging pile and power supply equipment, and sending the fault codes and the information to the fault judgment module; the fault judgment module is used for determining the fault position and level according to the information sent by the information acquisition module; and the fault processing module is used for giving a warning or cutting off a power supply circuit according to the judgment result of the fault judgment module. By analyzing the integrated safety action mechanism among the power battery, the charging pile and the power supply equipment and performing corresponding safety decision and control execution according to the fault influence type, diagnosis of the charging fault of the electric vehicle can be quickly realized, the fault point can be found out, and the charging safety of the electricvehicle is effectively improved.

    本发明公开了一种电动汽车充电故障智能诊断系统及方法。所述诊断系统包括信息采集模块、故障判断模块和故障处理模块,所述信息采集模块用于获取动力电池、充电桩、供电设备的故障代码、通断状态信息以及运行状态信息,并发送至故障判断模块,所述故障判断模块根据信息采集模块传递的信息故障所在位置以及故障级别,所述故障处理模块根据故障判断模块的判断结果进行告警提示或切断供电电路。本发明针通过分析动力电池、充电桩、供电设备之间一体化安全作用机理,并根据故障影响类型,进行相应的安全决策和控制执行,能够快速实现电动汽车充电故障的诊断,找出故障点,有效提高电动汽车充电安全。
