PROBLEM TO BE SOLVED: To provide a power receiver capable of easily and inexpensively performing alignment with appropriate accuracy.SOLUTION: A power receiver comprises: a secondary coil for receiving power in a non-contact manner from a primary coil disposed on a plane having a longitudinal direction and a lateral direction orthogonal to each other; a drive unit capable of displacing the secondary coil's relative position on the plane to the primary coil; a display unit; and a processing unit for processing video to be displayed on the display unit. The processing unit determines a target area on the plane, the target area including the primary coil; calculates the relative position and an inclination of the secondary coil against the primary coil on the basis of a coupling coefficient between the primary coil and the secondary coil and a temporal variation in the coupling coefficient; and displays the relative position and the inclination of the secondary coil in a predetermined display mode on the display unit. A display mode in the case that the secondary coil is not included in the target area's lateral direction differs from that in the case the secondary coil is included in the target area's lateral direction.SELECTED DRAWING: Figure 18
【課題】適切な精度の位置合わせを容易かつ低コストに行うことができる受電装置を提供すること。【解決手段】受電装置は、互いに直交する前後方向と左右方向から成る平面に配設された1次コイルから非接触で受電する2次コイルと、1次コイルに対する2次コイルの平面上の相対位置を変位可能な駆動部と、表示部と、表示部に表示する映像を処理する処理部とを備える。処理部は、1次コイルを含む平面上の目標域を決定し、1次コイルと2次コイルの間の結合係数及び結合係数の時間変化に基づき、相対位置及び1次コイルに対する2次コイルの傾きを算出し、相対位置及び2次コイルの傾きを表示部に所定の表示態様で表示する。目標域の左右方向に2次コイルが含まれない場合の表示態様と、目標域の左右方向に2次コイルが含まれる場合の表示態様とが異なる。【選択図】図18
