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.

Abstract: A non-contact power charging, in which power transmission can be interrupted when foreign materials are deposited on a charge plate of the non-contact power charging system. A charging operation can be continuously maintained at a stable voltage even if a non-contact power receiving apparatus moves by touching or displacement on the charge plate of the non-contact power charging system in the charging operation. Charging efficiency is improved.

Abstract: Disclosed are a wireless multi-charger system capable of saving the total charging time of a large number of wireless power transmission devices since one wireless multi-power transmission device includes a plurality of the wireless power transmission devices so that a large number of the wireless power transmission devices can be charged with electricity, and preventing the damage of the wireless power transmission devices and the wireless multi-power transmission device although foreign substances are put on charger blocks that are not charged.

Abstract: A wireless power charging system has a wireless power transmission apparatus formed to charge a plurality of wireless power receiving apparatuses located in a short distance therefrom, wherein the total charging time for the wireless power receiving apparatuses is saved. The wireless power transmission apparatus has a main control unit and a resonant converter unit, which transmit the electric signal to the wireless power receiving apparatus via the resonance signal generated from a primary charge core in order to charge the wireless power receiving apparatuses. The wireless power transmission apparatus also includes an output signal conversion module for transmitting a converted electric signal to the resonant converter unit and a received signal process module for processing a signal transmitted from the wireless power receiving apparatus.

Abstract: A battery pack comprising a battery cell having electrode terminals formed on an upper surface of the battery cell, and a protective circuit module (PCM) block mounted on the battery cell, wherein one or more connecting holes for electrical connection between the battery cell and the PCM block are perforated through the PCM block such that a connecting portion between the battery cell and the PCM block is exposed to the outside of the upper surface of the battery cell. The battery pack is lighter, compacter and miniaturized, thereby allowing an electronic device employing the battery pack to be reduced in an overall size, enhancing workability through a simplified assembling process, reducing manufacturing costs through reduction of the number of components, and enhancing productivity through reduction of the number of operating steps by eliminating additional installation steps.
