According to an embodiment of the present invention, a wireless charging device can provide a magnetic part with improved heat resistance and magnetic properties by including a magnetic part with a position change (ΔDR1) at 180.C of 0.07 or less and a small strain (thermal strain) at 180.C. The wireless charging device can prevent deformation and damage of the magnetic part during wireless charging, and further improve high-temperature stability and charging efficiency. Therefore, the wireless charging device can be usefully used in a means of transportation such as an electric vehicle which requires large-capacity power transmission between a transmitter and a receiver.
일 구현예에 따른 무선충전 장치는 180℃에서의 위치 변화(ΔDR1)가 0.07 이하로 180℃에서의 변형률(열 변형률)이 적은 자성부를 포함함으로써, 내열 특성 및 자성 특성이 향상된 자성부를 제공할 수 있고, 무선충전 시 상기 자성부의 변형 및 파손을 방지하고, 고온 안정성 및 충전 효율을 더욱 향상시킬 수 있다. 따라서 상기 무선충전 장치는 송신기와 수신기 간의 대용량의 전력 전송을 요구하는 전기 자동차 등의 이동 수단에 유용하게 사용될 수 있다.
