The invention provides a relay adhesion detection circuit and charging equipment, which are applied to the technical field of detection, and the circuit comprises a relay, a first oscillation module and a voltage division module, the first end of the first oscillation module is connected with the first end of the relay, the second end of the first oscillation module is connected with the vehicle body ground, the first end of the voltage dividing module is connected with the second end of the relay, and the second end of the voltage dividing module is connected with the vehicle body ground. In the relay adhesion detection circuit, whether the relay is adhered or not is judged through the change of the first oscillation module before and after the relay is disconnected, one end of the voltage division module is connected with the relay, and the other end is connected with the vehicle body, so that potential safety hazards caused by internal high voltage are reduced, and the safety of the relay adhesion detection circuit is improved.

    本申请提供一种继电器粘连检测电路及充电设备,应用于检测技术领域,该电路包括继电器、第一振荡模块和分压模块;所述第一振荡模块的第一端与所述继电器的第一端连接,所述第一振荡模块的第二端与车身地连接,所述分压模块的第一端与所述继电器的第二端连接,所述分压模块的第二端与所述车身地连接。该继电器粘连检测电路中,通过继电器断开前后,第一振荡模块的变化来判断继电器是否粘连,而分压模块一端与继电器连接,一端与车身地连接,减少了内部高压造成的安全隐患,从而提高了继电器粘连检测电路的安全性。
