A coil alignment control method and apparatus for wirelessly charging a moving object of the present invention comprise the steps of: aligning and controlling a power receiving direction surface of a power receiving coil of a moving object to be parallel with a power transmitting direction surface of a power transmitting coil of a wireless charging and transmitting station; controlling the alignment so that a winding center area of the power receiving coil is aligned with a winding center area of the power transmission coil; and controlling the alignment so that an interval between the power transmitting coil and the power receiving coil is close to a set interval. The wireless power transmission efficiency can be maximized by aligning the winding center area of the power transmitting coil and the winding center area of the power receiving coil to be close to each other in a state in which the power transmitting direction surface of the power transmitting coil is parallel with the power receiving direction surface of the power receiving coil.
본 발명의 이동체 무선충전을 위한 코일 정렬 제어 방법 및 장치는 무선충전 송전스테이션의 송전코일의 송전 방향면에 대하여 이동체의 수전코일의 수전 방향면이 평행이 되도록 정렬 제어하는 단계와 수전코일의 권선중심영역이 송전코일의 권선중심영역에 정렬되도록 정렬 제어하는 단계 그리고 송전코일과 수전코일의 간격이 설정된 간격으로 근접되도록 정렬 제어하는 단계를 포함하여, 송전코일의 송전 방향면과 수전코일의 수전 방향면을 평행상태에서 송전코일의 권선중심영역과 수전코일의 권선중심영역이 근접하여 정렬되게 함으로 무선전력전송효율을 극대화할 수 있다.
