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 when the secondary coil is included in the target area's lateral direction, displays the relative position and either of the inclination of the secondary coil and a corrected inclination of the secondary coil on the display unit. A display mode of the relative position to be displayed on the display unit is changed depending on a variation in the longitudinal direction in the relative position.SELECTED DRAWING: Figure 17
【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、目標域の左右方向に2次コイルが含まれる場合、相対位置、及び2次コイルの傾き又は2次コイルの補正した傾きを表示部に表示し、相対位置の前後方向の変化に応じて、表示部に表示する相対位置の表示態様を変える。【選択図】図17
