<p>PURPOSE: A wireless power transmission system for wirelessly charging a plurality of devices is provided to control wireless power transmission to a plurality of devices, thereby improving the efficiency of the system. CONSTITUTION: A plurality of wireless chargers are prioritized. The priority data is sent to all the wireless chargers. Wireless power is sequentially transmitted to a plurality of the wireless chargers according to the priority. The current and voltage of a wireless power transmission device are detected. A first impedance matching is performed by the detection.
