Abstract
A power reception apparatus includes a plurality of power extraction coils that extract power from a coil being a power supply source, a switch that selects one of the plurality of the power extraction coils and connects the selected power extraction coil to a battery, and a controller that senses a charging state of the battery and changes over the switch. The plurality of the power extraction coils are different from each other in terms of a diameter, the number of turns, or a distance from the coil being the power supply source.
