Abstract

Wireless energy transmission methods and wireless energy sending devices are provided. The method comprises: transmitting, according to remaining energy information of at least one preferential device among multiple wireless energy receiving devices, wireless energy to at least one of the at least one preferential device, until a predetermined energy standard corresponding to the preferential device on which wireless energy transmission is performed is reached. The methods and devices can enable one or more wireless energy receiving devices to be preferentially charged as wanted by a user in a process that a wireless energy sending device transmits energy to multiple wireless energy receiving devices.
