Wireless power transmission system, and method of controlling transmission and reception of resonance power

摘要

A resonance power transmission system, and a method of controlling transmission and reception of a resonance power are provided. According to one embodiment, a method of controlling resonance power transmission in a resonance power transmitter may include: transmitting resonance power to a resonance power receiver, the resonance power having resonance frequencies which vary with respect to a plurality of time intervals; and receiving, from the resonance power receiver, information regarding the resonance frequency having the highest power transmission efficiency among the resonance frequencies used in the time intervals.

主权项

1. A method, executed by a power receiver, of controlling wireless power reception, the method comprising:
receiving, from a power transmitter, a first wireless power in each time interval among a plurality of time intervals, wherein a resonance frequency corresponding to the first wireless power received in each time interval is different from resonance frequencies in all other time intervals among the plurality of time intervals; transmitting, to the power transmitter, information about an amount of the first wireless power received in each time interval; and receiving, from the power transmitter, a second wireless power having a resonance frequency with a highest power transmission efficiency, selected based on the information about the amount of the first wireless power received in each time interval; charging the power receiver with the received second wireless power.
