PURPOSE: A wireless charging apparatus is provided to stably maintain the efficiency of charging even if an electric vehicle is charged by magnetic induction, a feeding pad which is installed on the bottom in a specific space and a collecting pad which is mounted on the electric vehicle have a deviation in every direction within a determined range. CONSTITUTION: A wireless charging apparatus includes: a collecting pad(20) which is mounted at the lower portion of an electric vehicle, in which a battery is embedded, and receives power from the outside through magnetic induction by having a pad shape, around which a collection coil is wound; a collecting pad(10) which has a pad shape, around which a collection coil is wound, is installed on the ground surface(E) of a specific space in order to transferring power to the collecting pad by magnetic induction, and is formed relatively wider than the width of the collecting pad so as to have the power transfer characteristic the same as the event where the collecting pad and the horizontal direction arraignment correspond with each other even in the case where the collecting pad and the horizontal direction arraignment do not correspond with each other; and a stopper(30) installed on the ground to be spaced from the collecting pad by the determined distance in order to secure the front/back direction arraignment of the feeding pad and the collecting pad when the electric vehicle is parked. |
