Power supply system and method of controlling power supply system
First Claim
1. A power supply system comprising:
- a power supply coil and a power supply-side resonance coil that are provided at a facility;
a power receiving coil and a power receiving-side resonance coil that are provided for a mobile unit;
a power supply-side detection unit that detects a position of the power supply-side resonance coil;
a power receiving-side detection unit that detects a position of the power receiving-side resonance coil; and
an adjustment unit that adjusts a relative position of the power supply coil with respect to the power supply-side resonance coil and a relative position of the power receiving coil with respect to the power receiving-side resonance coil on the basis of the position of the power supply-side resonance coil and the position of the power receiving-side resonance coil.

10. A power supply system comprising:
-
a power supply coil and a power supply-side resonance coil that are provided at a facility; a power receiving coil and a power receiving-side resonance coil that are provided for a mobile unit; a power supply efficiency detection unit that detects a power supply efficiency that indicates a transmission efficiency of electric power; and an adjustment unit that, after the mobile unit stops around the facility, changes a relative position between the power supply coil and the power supply-side resonance coil and a relative position between the power receiving coil and the power receiving-side resonance coil within a predetermined range, and that adjusts the relative positions within the predetermined range so as to substantially maximize the power supply efficiency detected by the power supply efficiency detection unit.
