The invention discloses an electric vehicle charging protection device. The device comprises a data processing unit, a temperature monitoring unit used for acquiring the circuit temperature, a currentmonitoring unit used for acquiring the circuit current, a voltage monitoring unit used for acquiring the circuit voltage, a leakage current monitoring unit used for acquiring the circuit leakage current, a switching unit used for switching acquisition circuits, and a control unit used for cutting off the circuit. The temperature, the current, the voltage and the leakage current of a circuit are acquired through the temperature monitoring unit, the current monitoring unit, the voltage monitoring unit and the leakage current monitoring unit, and whether the circuit is abnormal or not is judgedfrom multiple angles, so that the accuracy of circuit judgment is improved. Meanwhile, the effect of switching the acquisition circuits can be achieved through the switching unit, the processing capacity of a data processing center is reduced, the data processing unit can correspondingly process different acquired data, and the situation that the judgment result is wrong due to disorder of the data is avoided.

    本发明公开了一种电动车充电保护装置,包括数据处理单元、用于采集电路温度的温度监测单元、用于采集电路电流的电流监测单元、用于采集电路电压的电压监测单元、用于采集电路漏电流的漏电流监测单元、用于切换采集电路的切换单元和用于切断电路的控制单元。通过温度监测单元、电流监测单元、电压监测单元和漏电流监测单元采集电路的温度、电流、电压和漏电流,从多个角度判断电路是否出现异常情况,从而提高电路判断的准确率,同时,通过切换单元,能够实现切换采集电路的效果,不仅降低数据处理中心的处理能力,数据处理单元还能够针对不同的采集数据进行相应的处理,避免了数据出现错乱而导致判断结果出错的情况发生。
