Wireless power charging system
First Claim
1. A wireless power charging system comprising:
- a wireless power transmission apparatus for transmitting a power signal from a primary core; and
a wireless power receiving apparatus for receiving the power signal transmitted from the primary core of the wireless power transmission apparatus via a secondary core and charging a battery cell by the control of a receiving control unit,wherein the wireless power transmission apparatus comprises a transmission shield panel in the side of the primary core to shield the electromagnetic field generated from the primary core, and the wireless power receiving apparatus includes a receiving shield panel in the side of the secondary core to shield an electromagnetic field generated from the secondary core, the receiving shield panel having an area smaller than that of the transmission shield panel and containing greater sendust compared to the transmission shield panel.

Abstract
A non-contact power charging system includes a wireless power transmission apparatus 10 for transmitting a power signal from a primary core 14 via a resonant converter 13 by the control of a transmission control unit 12; and a wireless power receiving apparatus 20 for receiving the power signal transmitted from the primary core 14 of the wireless power transmission apparatus 10 via a secondary core 24 and charging a battery cell 21 by the control of a receiving control unit 22. The wireless power receiving apparatus 20 includes a receiving shield panel 25 and an eddy current reducing member 26 in the side of the secondary core 24 to shield an electromagnetic field generated from the secondary core 24, to thereby protect the charging system and the battery pack from the electromagnetic field.
