The invention relates to the technical field of charging, in particular to a charging equipment protection method and system, and the method comprises the steps: obtaining a rated charging parameter of a current charging vehicle, and carrying out the matching of a corresponding charging threshold value based on the rated charging parameter; dynamically matching corresponding power supply parameters based on the rated charging parameters and the available charging power of the charging equipment, and charging; matching a variable sampling frequency based on the power supply parameters, and acquiring charging current data and charging voltage data of the charging equipment by adopting the variable sampling frequency; if the charging current data is greater than preset current data and/or the charging voltage data is greater than a charging threshold value and lasts for a preset duration, acquiring a control authority between a controller of the charging equipment and a contactor, and controlling the contactor to be disconnected; if the charging current data and the charging voltage data return to zero, and the external output of the charging equipment is in a closed state; if yes, the control authority between the controller and the contactor of the charging equipment is recovered, and the charging safety is improved.

    本发明涉及充电技术领域,具体涉及一种充电设备保护方法及系统,包括:获取当前充电车辆的额定充电参数,并基于额定充电参数匹配对应的充电阈值;基于额定充电参数和充电设备可用充电功率动态匹配对应的供电参数并进行充电;基于供电参数匹配可变采样频率,并采用可变采样频率获取充电设备的充电电流数据和充电电压数据;若所述充电电流数据大于预设电流数据和/或所述充电电压数据大于充电阈值,且持续预设时长,则获取充电设备的控制器与接触器之间的控制权限,并控制所述接触器断开;若所述充电电流数据和所述充电电压数据归零,且充电设备的对外输出为关闭状态;则恢复充电设备的控制器与接触器之间的控制权限,提高充电安全性。
