Abstract: According to an embodiment, an electronic device may include a battery, a resonance circuit, a rectifier, a DC/DC converter, a charger, a switch, an overvoltage protection circuit configured to perform an overvoltage protection operation or to stop the overvoltage protection operation based on the voltage at the output terminal of the rectifier, a control circuit, and a communication circuit, and the control circuit may be configured to: based on a periodic repetition of a performance of the overvoltage protection operation and a stop of the overvoltage protection while the switch is in an off state, identify a first period during which the overvoltage protection operation is stopped, based on the first period, identify an expected voltage at an output terminal of the rectifier, to be expected, wherein the expected voltage is a voltage if the switch is in an on state, based on the expected voltage, identify whether an occurrence of an overvoltage is expected if the switch is in the on state, and control the communication circuit to transmit a communication signal including information about whether the occurrence of the overvoltage is expected.
