1. A system for wireless charging control, comprising:
- a power transmitting unit configured to include a power supply unit supplying charging power for contactless charging using a commercial power supply, a DC/RF conversion unit controlling a supply amount of the charging power and converting the controlled charging power into a wireless signal, and a first common antenna unit transmitting the wireless signal converted by the DC/RF conversion unit; and
a receiving charging unit configured to include a second common antenna unit receiving the wireless signal from the first common antenna unit, an RF/DC conversion unit converting the wireless signal received by the second common antenna unit into the charging power for contactless charging, and a battery unit performing the contactless charging using the charging power transmitted from the RF/DC conversion unit.

8. A method for wireless charging control, comprising:
-
determining whether a power transmitting unit contacts a receiving charging unit using at least one sensor; as the determination result of the determining of the contact, if it is determined that the power transmitting unit contacts the receiving charging unit, transmitting a unique ID code of the power transmitting unit to the receiving charging unit; transmitting a receiving ID code of the receiving charging unit and a current state of charge information of the battery unit, which are converted into an RF signal depending on the unique ID code received from the power transmitting unit, from the receiving charging unit to the power transmitting unit; performing a control, by a first control unit of the power transmitting unit, to determine the RF signal; and performing contactless charging by controlling a supply amount of charging power supplied from the power transmitting unit to the receiving charging unit depending on the current state of charge information of the RF signal in the controlling. - View Dependent Claims (9, 10)
