Document Type and Number:
WIPO Patent Application WO/2015/161723
Kind Code:
A1
Abstract:
Wireless energy transmission method and wireless energy sending device (Tx, 200) are provided. The wireless energy transmission method comprises: transmitting wireless energy to a first wireless energy receiving device (Rx) with the minimum remaining energy level among multiple wireless energy receiving devices (S130); and when the remaining energy level of the first wireless energy receiving device (Rx) is a preset value higher than the remaining energy level of a second wireless energy receiving device (Rx) among the multiple wireless energy receiving devices (Rx), stopping transmitting wireless energy to the first wireless energy receiving device (Rx) and starting to perform wireless energy transmission on the second wireless energy receiving device (S170). The method and the device can implement balanced states of charge for wireless energy receiving devices (Rx) in a wireless energy transmission process, and make it convenient for a user to use multiple wireless energy receiving devices (Rx).
