The invention provides a charging gun fault processing method and system, and the method comprises the steps: determining a fault power module and a normal power module in a charging gun according toa preset fault judgment condition; disconnecting a relay of the fault power module, and controlling the normal power module to output preset current; judging whether the fault power module returns tonormal or not by utilizing a preset fault recovery condition; and if the fault power module returns to normal, closing a relay of the fault power module, and controlling the normal power module and the fault power module switched again after recovery to output preset current. In the scheme, the fault power module and the normal power module are determined through the fault judgment condition, therelay of the fault power module is disconnected, and the normal power module normally outputs the preset current; when the fault power module returns to normal, the relay of the fault power module isclosed; and when the output voltage of the charging gun is abnormal, the charging process of the charging gun does not need to be completely stopped, the charging continuity is ensured, and the user experience is improved.
本发明提供了一种充电枪的故障处理方法及系统,该方法为:根据预设的故障判断条件,确定充电枪中的故障功率模块和正常功率模块;断开故障功率模块的继电器,控制正常功率模块输出预设电流;利用预设的故障恢复条件,判断故障功率模块是否恢复正常;若故障功率模块恢复正常,闭合故障功率模块的继电器,控制正常功率模块和恢复后重新投切的故障功率模块输出预设电流。本方案中,通过故障判断条件确定故障功率模块和正常功率模块,断开故障功率模块的继电器,正常功率模块正常输出预设电流。当故障功率模块恢复正常后,闭合故障功率模块的继电器。在充电枪输出电压异常时,不需要完全停止充电枪的充电流程,保证充电持续性和提高用户的使用体验。
