The present invention relates to an effective contactless power transmitting device for an electric vehicle. More specifically, the effective contactless power transmitting device for an electric vehicle comprises: a power supply plate provided below a surface of a ground and having a coil part to receive power; and a current collector plate separated from the power supply plate and having a coil part collecting a magnetic field generated in the power supply plate and wireless charged. The coil part of the power supply plate and the coil part of the current collector plate have a spiral form. A plurality of conductors are formed in the coil part of the power supply plate and the coil part of the current collector plate, respectively. Therefore, the effective contactless power transmitting device for an electric vehicle can effectively supply and collect current even when a vehicle is stopped or parked, can be small, and can be adopted without a change in structure of an existing vehicle.

    본 발명은 효율적인 전기자동차용 비접촉 전력전송장치에 관한 것으로, 보다 구체적으로, 비접촉 전력전송장치는 지표면 아래에 구비되어 전력을 공급받는 코일부를 구비한 급전판과, 상기 급전판과 이격되어 상기 급전판에서 생성되는 자기장을 수렴하여 무선충전되는 코일부를 구비한 집전판을 구비한 전기자동차용 비접촉 전력전송장치에 있어서, 상기 급전판의 코일부와 상기 집전판의 코일부는 나선 형태로 형성되고, 상기 급전판의 코일부 및 상기 집전판의 코일부에는 각각 복수의 도전체가 형성한다. 이와 같은 방법으로, 정차 혹은 주차중에서도 효율적으로 급, 집전이 가능하면서도 소형일 뿐만 아니라 기존 차량의 구조변경없이 채용되며 제작시 경제성이 확보될 수 있다.
