The present invention discloses a wireless power transmission method which receives external wireless power by using field winding of an operating motor of an electric vehicle in a wireless power transmission system, and a vehicle assembly and an electric vehicle using the same. The electric vehicle wireless power transmission method comprises: a step of performing communication for charging a battery of an electric vehicle by a vehicle controller mounted in an electric vehicle or a vehicle assembly controller connected with the vehicle controller, and a control device or management device, or a ground assembly controller of a charger connected with a primary coil or a primary pad for transmitting wireless power, positioned outside the electric vehicle; and a step of connecting the battery to field winding of an operating motor of the electric vehicle before beginning of wireless power transmission. In addition, the battery is charged by power that is magnetically induced from the primary coil to the field winding.

    무선 전력 전송 시스템에서 전기차의 구동모터의 계자권선을 이용하여 외부의 무선 전력을 수신하는 무선 전력 전송 방법 및 이를 이용하는 차량 어셈블리와 전기차가 개시된다. 전기차 무선 전력 전송 방법은, 전기차에 탑재된 차량 제어기 또는 차량 제어기에 연결되는 차량 어셈블리 컨트롤러와 전기차의 외부에 위치하는 무선 전력 전송용 일차 코일이나 일차 패드에 연결되는 충전기의 제어장치나 관리장치 또는 그라운드 어셈블리 컨트롤러가 전기차의 배터리 충전을 위한 통신을 수행하는 단계, 및 무선 전력 전송을 시작하기 전에 전기차의 구동모터의 계자권선에 배터리를 연결하는 단계를 포함하며, 배터리는 일차 코일로부터 계자권선에 자기(magnetic) 유도되는 전력에 의해 충전된다.
