MOBILE TERMINAL
First Claim
1. A mobile terminal comprising:
- a battery configured to be charged in a normal charging mode and to be charged in a fast charging mode;
a power pick-up unit configured to receive power from a wireless charging device based on magnetic induction, to provide a charging voltage based on the received power, and to supply the charging voltage to the battery; and
a control unit configured to increase the power by controlling an impedance of the power pick-up unit and to increase a charging speed of the battery based on the increased power when the battery is to be charged in the fast charging mode.

Abstract
Disclosed is a mobile terminal capable of wirelessly charging a battery using a magnetic induction method. The mobile terminal may include a battery configured to support normal charging mode and fast charging mode, a power pick-up unit configured to pick up power transmitted by a wireless charging device based on magnetic induction, generate a charging voltage based on the pick-up power, and supply the charging voltage to the battery, and a control unit configured to increase the pick-up power by controlling an impedance of the power pick-up unit and increase a charging speed of the battery based on the increased pick-up power in the fast charging mode. The mobile terminal can increase the charging speed of the battery in such a way as to increase pick-up power from power transmitted by the wireless charging device by varying the impedance of the power pick-up unit in fast charging mode.
