A wireless charging method and apparatus are provided. Identification information is transmitted, through a near field communication antenna, to a wireless power transmitter for an authentication process of the electronic device, if the electronic device is put on the wireless power transmitter for wireless charging and a near field communication controller is in an initial or idle state. Wireless power is received through a wireless power receiving antenna from the wireless power transmitter after the authentication process. Wireless charging is performed through a wireless charging controller by using the received wireless power. It is determined whether the wireless charging is complete. A charging completion signal is transmitted, through the near field communication antenna, to the wireless power transmitter based on the determining.

Wireless charging apparatus and method

A wireless charging method and apparatus are provided. A non-contact wireless local communication unit performs non-contact wireless local communication for wireless charging authentication through a non-contact wireless local communication antenna. A wireless power receiver receives supply power from a wireless power transmitter by using a resonator resonating on a resonance frequency equal to that of the wireless power transmitter after the wireless charging authentication. A charging controller performs wireless charging by using the supply power received by the wireless power receiver. One or more switches switch between a connection between the non-contact wireless local communication antenna and the non-contact wireless local communication unit, and a connection between the wireless power receiver and the charging controller.
