The present invention relates to wireless charging of an electric vehicle. A wireless charging system comprises two or more antennas and calculates the distance between the antenna and the electric vehicle using an RSSI value, and calculates the position of the electric vehicle obtained by a triangulation method using the position information of each antenna. According to the triangulation method, since not only the distance between ta wireless charging transmitting pad and a receiving pad of the electric vehicle, but also the relative position of the transmitting pad and the receiving pad can be accurately obtained, the improvement of the wireless charging efficiency according to the alignment of the transmitting pad and the receiving pad can be expected.

    본 발명은 전기자동차의 무선충전에 관한 것으로, 무선충전 시스템은 둘 이상의 안테나를 포함하며 안테나와 전기자동차 사이의 거리를 RSSI값을 이용하여 구하고 안테나 각각의 위치정보를 이용하여 삼각측량 방식으로 전기자동차의 위치를 구한다. 삼각측량 방식에 의하면 단순히 무선충전 송신패드와 전기자동차의 수신패드 사이의 거리뿐 아니라 송신패드와 수신패드의 상대적인 위치도 정확하게 구할 수 있기 때문에, 송신패드와 수신패드의 정렬에 따른 무선충전 효율의 향상을 기대할 수 있다.
