A contactless power transmission device for a small electric vehicle includes: a feed plate embedded in the ground to generate a magnetic field for charging; and a current collecting plate which is disposed at a predetermined interval from the feed plate and is wirelessly charged by converging the magnetic field generated by the feed plate, wherein the feed plate and the current collecting plate include a coil part formed in a disk shape with an empty center part by winding a coil in a spiral shape and a plurality of conductors arranged in a shape to surround a preset interval of at least one or more surfaces of the coil part. The contactless power transmission device for a small electric vehicle can perform efficient feeding and collection operations, can be applied without the structural modification of a conventional vehicle, and can reduce lateral deviation by generating a large amount of magnetic field eddy currents, in a small size.

    소형 전기자동차용 비접촉 전력전송장치는 지면에 매설되어, 충전을 위한 자기장을 발생시키는 급전판; 및 급전판과 소정간격을 형성하고 배치되어, 급전판에서 생성되는 자기장을 수렴하여 무선으로 충전되는 집전판을 포함하고, 급전판 및 집전판은, 코일이 나선형상으로 권회되어, 중심부가 비어있는 원판형상으로 형성되는 코일부 및 코일부의 적어도 하나 이상의 면의 소정간격을 감싸는 형상으로 배치되는 복수의 도전체를 포함한다. 소형 전기자동차용 비접촉 전력전송장치는 효율적인 급전 및 집전이 가능하고, 기존 차량의 구조변경 없이도 적용되며, 소형이면서도, 자기장 맴돌이 전류를 크게 발생시켜 좌우편차를 줄일 수 있다.
