일 구현예에 따른 무선충전 장치는 80℃에서의 인덕턴스 편차가 0 이상을 갖고, 자성부의 투자율 변화율(△P1)이 0/℃ 이상을 가짐으로써, 고온 안정성이 우수하여, 고온에서도 우수한 충전 효율을 유지할 수 있다. 따라서 상기 무선충전 장치는 송신기와 수신기 간의 대용량의 전력 전송을 요구하는 전기 자동차 등의 이동 수단에 유용하게 사용될 수 있다.

    A wireless charging device according to one embodiment has an inductance deviation at 80°C of 0 or more, and has a magnetic part that has a permeability change rate (ΔP1) of 0/°C or more, thus having excellent high-temperature stability, and being able to maintain excellent charging efficiency even at high temperature. Therefore, the wireless charging device can be useful in a transportation means such as an electric vehicle requiring large-capacity power transmission between a transmitter and a receiver.
