An electronic device and method and power supply are disclosed. The electronic device includes comprising a connector for electrically coupling with an external power supply unit, and a processor. The processor implements the method, which includes detecting a connection state with the external power supply unit, and detecting whether power supplied from the external power supply unit is abnormal, and controlling the power when the power supplied has an abnormal value. The power supply may include a connector for electrically coupling with an electronic device, and a processor for detecting a connection state with the electronic device, detecting whether power supplied to the electronic device by the power supply unit has an abnormal value, and controlling the supplied power when the power is abnormal.

Method for controlling power of electronic device and electronic device thereof

A charge device for controlling an abnormal charge request is provided. The charge device includes a controller that interrupts a charge path, when power is applied and that determines whether a charge request is an abnormal charge request through a detour charge path and that controls to maintain interruption of the charge path, if the charge request is an abnormal charge request. The controller may be further configured to interrupt the detour charge path, in response to determining that the charge request is a normal charge request; connect the charge path; and supply a charge current to the charge path.
