Alignment method and apparatus for transmitting and receiving coils of a wireless power transmission system for a vehicle are disclosed. The alignment method includes the steps of: moving a primary coil such that a reference center point of the primary coil is located on the primary coil or sequentially passes through a plurality of measurement points located outside the primary coil; measuring a physical quantity induced in the primary coil by a magnetic field or power of a secondary coil magnetically coupled to the primary coil at the reference center point and the measurement points; and calculating a relative position of the primary coil for the secondary coil based on the physical quantity at the reference center point and the measurement points. Accordingly, the present invention can improve power transmission efficiency and improve the convenience of a user.

    전기차 무선 전력 전송 시스템의 송수신 코일들에 대한 얼라인먼트 방법 및 장치가 개시된다. 얼라인먼트 방법은, 일차 코일의 기준 중심점이 일차 코일 상에 위치하거나 일차 코일의 외부에 위치하는 복수의 측정 지점들을 순차적으로 경유하도록 일차 코일을 이동하는 단계와, 일차 코일과 자기 결합하는 이차 코일의 전력 또는 자기장에 의해 일차 코일에 유도되는 물리량을 기준 중심점과 측정 지점들에서 측정하는 단계와, 기준 중심점과 측정 지점들에서의 물리량에 기초하여 이차 코일에 대한 일차 코일의 상대적인 위치를 계산하는 단계를 포함한다.
