PROBLEM TO BE SOLVED: To provide a feeding system that implements charging by keeping power supply efficiency intact, and provide a feeding system that implements a feeding service efficient for both a feeding user and a feeding provider.SOLUTION: A power transmission state of each power transmission section is monitored, and from a plurality of power transmission sections disposed in a power transmission apparatus, the power transmission section that is highest in transmission efficiency based on positional superiority is selected. In the selected power transmission section, a transmitting side resonance coil is maintained to be at the setting of a first resonance frequency to continue power transmission, and in the other unselected power transmission sections, transmitting side resonance coils are set at a second resonance frequency to stop power transmission. |
