WIRELESS POWER FEEDING SYSTEM, AND WIRELESS POWER FEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a power feeding system and a power feeding method that achieve a high convenience for a feed user on a power reception side, and that enable a feed provider (an entrepreneur) on a power feeding side (a power transmission side) to supply power without waste.

SOLUTION: A power feeding device supplying power to a power reception body wirelessly, detects a position and a resonance frequency of a power reception body to be supplied with the power, and controls a frequency of a power signal to be transmitted to the power reception body based on the detected information. An efficient power feeding service becomes possible by transmitting the power signal to the power reception body at an optimum frequency which allows a high power transmission efficiency.
