Title:
WIRELESS CHARGING APPARATUS AND TRANSPORTATION MEANS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/164087
Kind Code:
A1
Abstract:
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.
