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 15):
A wireless power transmission device capable of wirelessly transmitting power to a plurality of wireless power reception devices in a wireless power transmission system, the wireless power transmission device comprising:\n a power transmission unit that comprises at least one power transmission coil and transmits power to the wireless power reception devices; a power supply unit that supplies power to the power transmission unit; a transmission impedance matching unit that adjusts impedance between the power supply unit and the power transmission unit; and a transmission control unit that controls the power wirelessly transmitted to the wireless power reception devices, wherein the transmission control unit receives the charging state information of each batteries of the plurality of wireless power reception devices to control the wirelessly transmitted power based on the charging state information.
