전기차 무선 전력 전송에 사용되는 무선 전력 전송 패드 및 이를 구비하는 그라운드 어셈블리가 개시된다. 무선 전력 전송 패드는, x-방향에서 정의된 X-폭과 y-방향에서 정의된 Y-폭을 구비하고 중앙 공간을 구비하는 직사각 형태의 일차 코일, 일차 코일과 결합하는 페라이트, 및 일차 코일과 페라이트를 지지하는 하우징을 포함하고, 여기서 X-폭을 가진 일차 코일의 제1 부분에 대한 제1 단면적은, Y-폭을 가진 일차 코일의 제2 부분에 대한 제2 단면적보다 작다.

    Disclosed are a wireless power transmission pad used for an electric car wireless power transmission and a ground assembly having the same. The wireless power transmission pad comprises: a primary coil with a rectangular shape having the X-width defined in the x-direction and the Y-width defined by the y-direction, and having a central space; a ferrite connected with the primary coil; and a housing supporting the primary coil and the ferrite. A first cross-section area with respect to a first part of the primary coil having the X-width is smaller than a second cross-section area with respect to a second part of the primary coil having the Y-width.
