Abstract

A power reception apparatus includes a secondary coil which receives electric power in a non-contact manner from a primary coil which is provided on a plane defined by a front-rear direction and a left-right direction which are at right angles to each other, a drive part which can change a relative position on the plane of the secondary coil relative to the primary coil, a display unit, and a processing unit for processing an image to be displayed on the display unit. The processing unit calculates a relative position and a gradient of the secondary coil relative to the primary coil based on a coupling coefficient between the primary coil and the secondary coil, and a change with time in the coupling coefficient.
