A SYSTEM AND A METHOD FOR CHARGING MULTIPLE POWER RECEIVERS IN A WIRELESS CHARGING ENVIRONMENT

摘要

The present invention relates to a method for operating a power transmitter, the method comprising broadcasting a device discovery request, determining whether a discovery response is received from at least one power receiver receiving the device discovery request within a threshold response time, if the discovery response is not received from the at least one power receiver within the threshold response time, rebroadcasting the device discovery request, a predetermined number of times, if the discovery response is received from the at least one power receiver within the threshold response time, transmitting confirmation information to the at least one power receiver which transmitted the discovery response, and transmitting radiation to charge the at least one power receiver, when an acknowledgement is received from the at least one power receiver in response to the confirmation information.
