The present invention relates to a wireless charging electric vehicle and, more specifically, to magnetic shaping technology, wirelessly transmitting power to an electric vehicle through a magnetic-resonance-guided method, and a bidirectional wireless charging electric vehicle, capable of generating an inductive voltage by receiving an inductive magnetic field, generated by a current flowing between a feeding device and a collecting device, and then delivering the generated inductive voltage in order to transmit power. According to the present invention, provided is a bidirectional wireless charging method, making the collecting device and the feeding device supply power to each other in the electric vehicle system. The bidirectional wireless charging method, to which the magnetic shaping technology is applied, is used, and therefore, surplus electricity, stored in a battery of the electric vehicle for a long time, is able to be effectively used for a house or system through a variety of devices.

    본 발명은 무선충전 전기자동차에 관한 것으로서, 더욱 상세하게는 전기자동차에 자기공명유도 방식을 사용하여 무선으로 전력을 전송하는 자기형상화 기술에 대한 것이며, 급전장치 및 집전장치 상호간, 이들을 흐르는 전류에 의해 발생되는 유도자기장을 받아들임으로써 유도전압을 발생시키고 발생된 유도전압을 전달함으로써 전력을 전송하는 양방향 무선충전 전기자동차에 관한 것이다. 본 발명에 의하면, 무선충전 방식의 전기자동차 시스템에 있어서 집전장치와 급전장치가 서로 전력 공급을 하는 양방향 무선충전 방법을 제공하며, 양방향 전력전송을 위한 자기장 형상화 기술이 적용된 양방향 무선충전 방법을 사용함으로써 매우 높은 효율로 전기 자동차 배터리에 장시간 저장되는 잉여 전기를 계통 또는 가정에서 다양한 기기를 통하여 효과적으로 사용할 수 있다.
