Zusammenfassung:	A circuit for detecting a charger includes a first photoelectric coupler, a first switch, and a control circuit. By the first switch and the first photoelectric coupler, whether an external port is connected to the charger is detected. When the charger is connected to the external port, the first switch and the first photoelectric coupler are turned on, and then a first signal is output to the control circuit. Also, a method for detecting a charger and an electrochemical device. The circuit and method for detecting a charger and the electrochemical device have the advantages of low power consumption, high safety performance, high detection accuracy, low cost and the like, can accurately identify standard chargers and high-voltage illegal chargers, and can significantly improve the security and stability of a battery.
