Shielding Sheet and The Mefacturing Method of Wireless Charging System for Electric Vehicle

摘要

The present invention relates to a shielding sheet which comprises: a plurality of first shielding sheets arranged on a lower surface of a charging coil; and a plurality of second shielding sheets stacked on the first shielding sheet and having a relatively higher specific resistance than that of the first shielding sheet. A gap between the plurality of first shielding sheets and a gap between the plurality of second shielding sheets are arranged not to correspond to each other, thereby minimizing an air gap loss generated in the gap between the shielding sheets.
