Title:
WIRELESS POWER TRANSMISSION CONTROL METHOD AND WIRELESS POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/177860
Kind Code:
A1
Abstract:
A wireless power transmission control method includes a plurality of power transmission coils and a plurality of power receivers and wirelessly and simultaneously transmits the power output from said power transmission coils to at least two of said power receivers using magnetic field resonance or electric field resonance. The method obtains a single-body power transmission efficiency of said power transmission coils to each of said power receivers and a single-body requested power requested by each of said power receivers, divides said single-body requested power by said single-body power transmission efficiency to calculate the single-body transmission power of each of said power receivers, selects a first power receiver, the single-body transmission power of which becomes maximum, and controls said power transmission coils so as to maximize the power transmission efficiency to said first power receiver.
