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.

    L'invention, selon un mode de réalisation, concerne un dispositif de charge sans fil ayant un écart d'inductance à 80 °C supérieur ou égal à 0, et comportant une partie magnétique qui a un taux de variation de perméabilité (ΔP1) supérieur ou égal à 0/°C, ayant ainsi une excellente stabilité à température élevée, et pouvant maintenir une excellente efficacité de charge même à température élevée. Par conséquent, le dispositif de charge sans fil peut être utile dans un moyen de transport tel qu'un véhicule électrique nécessitant une transmission de puissance de grande capacité entre un émetteur et un récepteur.

    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.
