Wireless charging apparatus and method
First Claim
1. An apparatus for wirelessly charging at least one device, the apparatus comprising:
- a resonator that wirelessly transmits power for charging the at least one device;
a communication unit; and
a control unit configured to;
receive, through the communication unit, power state information from the at least one device,compare between a transmission cycle of each of the at least one device and a threshold cycle based on the power state information,determine, among the at least one device, a device with which the apparatus is to communicate during an allocation period based on the comparison between the transmission cycle of each of the at least one device and the threshold cycle,set a transmission cycle of the determined device based on the received power state information, andtransmit, through the communication unit, a message to the determined device including the set transmission cycle.

Abstract
The present invention relates to a method for adjusting a power information transmission period from a mobile terminal to be charged in a wireless charging apparatus. To this end, a wireless charging apparatus according to the present invention comprises: a communication unit for receiving power information from at least one mobile terminal; and a control unit for determining a transmission period of power information for each of the at least one mobile terminal based on the power information and adjusting the transmission period according to whether the power information is received from the at least one mobile terminal. As described above, the waste of resources, which may occur due to unnecessary packet transmission, can be reduced by adaptively adjusting the transmission period, thereby increasing the efficiency of power transmission.
