Abstract:
The present invention relates to a battery charging system using wireless power transmission, including a charging power supply device that comprises: a power supply unit that supplies power for wireless power transmission; a power transmission unit that comprises at least one power transmission coil and wirelessly transmits power for charging a battery; and a transmission impedance matching unit that matches the impedance between the power supply unit and the power transmission unit; and a battery charging device that receives power wirelessly transmitted from the charging power supply device through power reception coils individually corresponding to one or more batteries and charges the batteries. According to the present invention, a plurality of unit batteries can be simultaneously charged by one charging power supply device, that is, one transmission module. With this advantage, a plurality of battery cells can be simultaneously charged wirelessly without wires, and quick charging is also possible.

Claim (Index 11):
The battery charging system of  claim 1 , wherein the reception control unit of the battery charging device adjusts impedance of an impedance matching unit of each battery to control power charged to each battery.
