The invention provides a charging interface detection circuit, an electric vehicle and a charging pile. The charging interface detection circuit comprises a charging detection port, a first charging conduction circuit, a controller and a power supply chip. The controller is connected with the first charging conduction circuit through the first detection port and detects the on-off state of the first charging conduction circuit through the first detection port when the charging plug is inserted into the charging interface. The power supply chip is connected with the controller through an abnormal detection port and is connected with the first charging conduction circuit through an abnormal control port; the power supply chip detects whether the controller is abnormal in enabling or not through the abnormal detection port, and controls the first charging conduction circuit to be disconnected through the abnormal control port when detecting that the controller is abnormal in enabling, so that the controller is disconnected from the first charging conduction circuit. The circuit body of the charging interface detection circuit can be monitored in real time, the detection result is prevented from being influenced by abnormity of the circuit body of the charging interface detection circuit, and safety and reliability are achieved.

    本申请提供一种充电接口检测电路、电动汽车及充电桩。充电接口检测电路包括充电检测端口、第一充电导通电路、控制器及电源芯片。控制器通过第一检测端口与第一充电导通电路连接,并通过第一检测端口检测在充电插头插入充电接口时,第一充电导通电路的通断状态。电源芯片通过异常检测端口与控制器连接,且通过异常控制端口与第一充电导通电路连接;电源芯片通过异常检测端口检测控制器是否使能异常,且在检测到控制器使能异常时,通过异常控制端口控制第一充电导通电路断开,使控制器与第一充电导通电路断开。可实时监控充电接口检测电路的电路本身,避免因充电接口检测电路的电路本身出现异常而影响检测结果,安全可靠。
