Title:
WIRELESS POWER TRANSMISSION METHOD AND DEVICE IN WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/004116
Kind Code:
A1
Abstract:
The present invention relates to a wireless power transmission method in a wireless charging system supporting electromagnetic resonance and a device therefor. According to one embodiment of the present invention, a wireless power transmission method in a wireless power transmitter wirelessly supplying power to a wireless power receiver through a resonance phenomenon can comprise the steps of: entering a configuration state according to the application of power and performing booting; generating a random first standby offset when the booting is completed; and entering a power saving state at a point in time determined on the basis of the first standby offset, so as to initiate a beacon sequence. Therefore, the present invention has an advantage of enabling power loss caused by cross connection and device damage caused by heat generation in the wireless charging system to be minimized.
