The invention discloses a charging pile with an electronic leakage protection technology and a method thereof. The method comprises the following steps: acquiring a residual current signal in a charging loop; analyzing the residual current signal to obtain a residual current multi-scale correlation feature vector; and based on the residual current multi-scale correlation feature vector, determining whether to automatically cut off a charging power supply. Therefore, whether an electronic leakage risk occurs can be detected based on the residual current signal in the charging loop, so that whether a charging power supply is automatically cut off is judged, the safety of the charging pile is improved, and a fire accident caused by electronic leakage of the charging pile is avoided.
本发明公开了一种具有电子漏电保护技术的充电桩及其方法,其获取充电回路中的剩余电流信号;对所述剩余电流信号进行分析以得到剩余电流多尺度关联特征向量;以及,基于所述剩余电流多尺度关联特征向量,确定是否自动切断充电电源。这样,可以基于充电回路中的剩余电流信号来检测是否发生电子漏电风险,从而判断是否自动切断充电电源,以此来提高充电桩的安全性,避免充电桩电子漏电引发起火事故。
