The invention mainly relates to the technical field of fault diagnosis of a direct current charging pile, in particular to a flexible charging pile matrix switch adhesion fault positioning method. According to the method, a simulation test load is connected to the charging terminal of the flexible charging pile, the switch matrix is controlled to act regularly, and the fault position of the switch matrix is judged by observing the abnormal condition of power injected into the simulation test load.

    本发明主要涉及直流充电桩桩故障诊断技术领域,特指一种柔性充电堆矩阵开关发生粘连时的故障定位方法。该方法通过在柔性充电堆充电终端连接模拟测试负载,控制开关矩阵规则动作,观测注入模拟测试负载的功率的异常情况来判断开关矩阵的故障位置。
