Abstract:
A method for communication and power control of a wireless power transmitter, includes transmitting notice information to a wireless power receiver, and detecting a wireless power receiver based on the notice information, the wireless power receiver accessing the wireless power transmitter. The method further includes determining whether the wireless power receiver is to cease the accessing of the wireless power transmitter based on a power control and/or a power transmission efficiency, and transmitting a reset command to the wireless power receiver in response to the wireless power receiver being determined to incorrectly access the wireless power transmitter.
