본 발명은 전기자동차의 전력수신용 패드조립체 등에 대한 것으로, 전기자동차 등에 우수한 충전효율로 무선충전을 가능하게 하며 패드조립체에 충격이나 반복적인 진동이 가해져도 우수한 충전효율이 잘 유지될 수 있다.
Disclosed herein is a pad assembly for power reception of electric transportation, which includes a receiving pad configured to support a receiving coil, the receiving coil connected to an external component by a wire and positioned on the receiving pad, and a magnetic complex layer disposed above or below the receiving coil, in which the increment in inductance per unit density of the magnetic complex layer in the pad assembly after assembly is 25 %·cm3/g or less compared to before assembly. According to the present invention, wireless charging is possible with excellent charging efficiency for electric transportation, and the excellent charging efficiency can be maintained well even when an impact or repeated vibration is applied to the pad assembly.
