<p>PURPOSE: A wireless power transmission system for wirelessly charging a plurality of wireless devices is provided to supply the protocol and procedure of a control interface, thereby performing appropriate operation. CONSTITUTION: Firstly, test power is transmitted to a plurality of wireless chargers. The current and voltage of a wireless power transmission device are detected. A first impedance matching is performed by the detection. Secondly, test power is transmitted to a plurality of the wireless chargers. A second impedance matching is performed based on the received power information of the wireless chargers.
