Abstract
A wireless charging system can optimize charging efficiency regardless of a location of a mobile terminal. The wireless charging system wirelessly charges a mobile terminal using electromagnetic induction between a first coil included in a charging pad and a second coil included in the mobile terminal. The charging pad can detect a location of the mobile terminal on the charging pad. The charging pad can move the first coil to correspond to the detected location of the mobile terminal; and supply power to the first coil and charging a battery.

21. A terminal comprising:
-
a first coil configured to charge a battery using an induction current induced to the first coil by a magnetic field generated by an external device adjacent to the terminal; a communication unit configured to transmit a control signal to the external device, the control signal being a command requesting the external device to move a location of a second coil formed in the external device; and a control unit configured to determine a charging efficiency and to control the communication unit to transmit the control signal to the external device when the charging efficiency is determined to be less than a threshold. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A method of a terminal, the terminal comprising a first coil configured to charge a battery using an induction current induced to the first coil by a magnetic field generated by an external device adjacent to the terminal, the method comprising:
-
determining a charging efficiency; and transmitting a control signal to the external device when the charging efficiency is determined to be less than a threshold, the control signal being a command requesting the external device to move a location of a second coil formed in the external device. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A wireless charging system, comprising:
-
a charging pad configured to generate a magnetic field when power is supplied; and a terminal adjacent to the charging pad, the terminal comprising; a first coil configured to charge a battery using an induction current induced to the first coil by a magnetic field generated by the charging pad; a communication unit configured to transmit a control signal to the external device, the control signal being a command requesting the external device to move a location of a second coil formed in the charging pad; and a control unit configured to determine a charging efficiency and to control the communication unit to transmit the control signal to the charging pad when the charging efficiency is determined to be less than a threshold. - View Dependent Claims (38, 39, 40)
