A wireless charging apparatus according to an embodiment includes a magnetic unit with a low strain rate (thermal strain) at 180 ℃, wherein a position change (△DR1) at 180 ℃ is 0.07 or less, to thereby provide the magnetic unit with improved heat resistance and magnetic properties and prevent deformation and damage of the magnetic unit during wireless charging, and further improve the high temperature stability and charging efficiency. Therefore, the wireless charging apparatus can be efficiently used in personal transportation means such as electric motorcycles, electric kickboards, electric scooters, electric wheelchairs, and electric bicycles, as well as transportation means such as electric vehicles requiring large-capacity power transmission between a transmitter and a receiver.

    Un appareil de charge sans fil selon un mode de réalisation comporte une unité magnétique présentant un faible taux de déformation (déformation thermique) à 180 °C, un changement de position (△DR1) à 180 °C étant de 0,07 ou moins, pour ainsi doter l'unité magnétique d'une résistance à la chaleur et de propriétés magnétiques améliorées et empêcher une déformation et un endommagement de l'unité magnétique pendant une charge sans fil, et améliorer en outre la stabilité à haute température et l'efficacité de charge. Par conséquent, l'appareil de charge sans fil peut être utilisé efficacement dans des moyens de transport personnels tels que des motocyclettes électriques, des trottinettes 3 roues électriques, des trottinettes électriques, des chaises roulantes électriques et des vélos électriques, ainsi que des moyens de transport tels que des véhicules électriques nécessitant une transmission de puissance de grande capacité entre un émetteur et un récepteur.

    일 구현예에 따른 무선충전 장치는 180℃에서의 위치 변화(△DR1)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 수단뿐만 아니라, 전기 오토바이, 전동 킥보드, 전동 스쿠터, 전동 휠체어, 및 전기 자전거 등의 다양한 개인형 이동 수단 등에 유용하게 사용될 수 있다.
