The invention relates to the technical field of charging piles, and particularly discloses a charging pile fault detection method and a charging pile, the charging pile comprises a power output device, a circuit breaker, a charging head, a voltage monitor, a controller and an audible and visual alarm, and the power output device is connected with the charging head through the circuit breaker; the charging pile fault detection method comprises the steps that S10, a voltage monitor monitors the output voltage of power output equipment; s20, if the output voltage value of the power output equipment exceeds a preset safety value a, executing S30, otherwise, executing S10; s30, the circuit breaker disconnects the power output device and the charging head and transmits a disconnection signal to the controller; and S40, when the controller receives a disconnection signal of the circuit breaker, the controller controls the audible and visual alarm to work. According to the method, when the power output equipment is damaged or breaks down, the power supply of the charged electric vehicle cannot be damaged, and fire hazards cannot occur to nearby residents and buildings.
本发明涉及充电桩技术领域,具体公开了充电桩故障检测方法及充电桩,充电桩包括电力输出设备、断路器、充电头、电压监测器、控制器和声光报警器,电力输出设备通过断路器与充电头连接;充电桩故障检测方法包括:S10:电压监测器监测电力输出设备的输出电压;S20:若电力输出设备的输出电压值超出预设安全值a时,则执行S30,否则执行S10;S30:断路器将电力输出设备和充电头断开且将断开信号传至控制器;S40:控制器接到断路器的断开信号时,控制器控制声光报警器工作。该方法可以在电力输出设备发生损坏或故障时,其不会对充电的电动车的电源造成损坏,也不会出现火灾对附近的居民及建筑物造成危险。
