Mobile terminal and USB dedicated charger determining method thereof
First Claim
1. A method of determining a charger of a mobile terminal, the method comprising:
- receiving, via a controller of the mobile terminal, a connection signal indicating the charger is connected to the mobile terminal;
setting, via the controller, a charging current of the charger for charging the mobile terminal and increasing the set charging current in predetermined current units;
measuring, via the controller, an actual current received from the charger and applied to the mobile terminal;
comparing, via the controller, the set charging current with the measured actual current;
determining, via the controller, a charging sector of the charger when the set charging current is larger than the measured actual current for a first predetermined amount of time; and
calculating, via the controller, a charging current capacity of the charger using the determined charging sector.

10. A mobile terminal, comprising:
-
a wireless communication unit configured to wirelessly communicate with at least one other entity; an interface configured to receive a connection signal indicating a charger is connected to the mobile terminal; and a controller configured to set a charging current of the charger for charging the mobile terminal and increase the set charging current in predetermined current units, to measure an actual current received from the charger and applied to the mobile terminal, to compare the set charging current with the measured actual current, to determine a charging sector of the charger when the set charging current is larger than the measured actual current for a first predetermined amount of time, and to calculate a charging current capacity of the charger using the determined charging sector. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
