METHOD FOR WIRELESS CHARGING AND APPARATUS FOR THE SAME

摘要

PURPOSE: A wireless charging device and a method thereof efficiently receive power by including multiple power supply devices on the periphery. CONSTITUTION: A wireless power receiving device transmits a power supply device search signal (202). A power supply device search response signal is received (204,206). Multiple power supply devices are recognized. Power supply is requested to a first power supply device (212). Power supply is requested to a second power supply device according to charging rejection signals (220).
