WIRELESS CHARGING APPARATUS AND METHOD
First Claim
1. A wireless charging apparatus comprising:
- a non-contact wireless local communication unit for performing non-contact wireless local communication for wireless charging authentication through a non-contact wireless local communication antenna;
a wireless power receiver for receiving 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 for performing wireless charging by using the supply power received by the wireless power receiver; and
one or more switches for switching 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.

Abstract
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.
