The invention discloses a state monitoring method, device and equipment for a charging contactor of a vehicle. The method comprises the following steps: in response to a state monitoring instruction of a preset charging contactor, detecting whether a charging gun head of charging pile equipment is plugged into a charging interface of the vehicle, and obtaining a control instruction sent by the vehicle for the charging contactor and an on-off state of the charging contactor detected by the vehicle; when the charging gun head is not plugged, the control instruction is an off control instruction, and the switch state is a closed state, if the switch state is continuously monitored to be the closed state within the preset duration, reporting a monitoring result that the charging contactor is in an adhesion fault state; otherwise, reporting a monitoring result that the charging contactor is in the off state. By adopting the method of the invention, the accuracy of reporting the state monitoring result of the charging contactor can be effectively improved, so that the safety and reliability of the vehicle charging process are ensured.

    本发明公开了一种车辆的充电接触器的状态监测方法、装置和设备。所述方法包括:响应于预设的充电接触器的状态监测指令,检测所述车辆的充电接口是否插接充电桩设备的充电枪头,并获取所述车辆发送的对所述充电接触器的控制指令和所述车辆检测到的所述充电接触器的开关状态;当未插接所述充电枪头、所述控制指令为断开控制指令,且所述开关状态为闭合状态时,若在所述预设时长内持续监测到所述开关状态为闭合状态,上报所述充电接触器处于粘连故障状态的监测结果;否则,上报所述充电接触器处于断开状态的监测结果。采用本发明实施例,能够有效地提高上报充电接触器的状态监测结果的准确性,从而保证车辆充电过程的安全可靠。
