Abstract

An electronic device and a method of controlling charging in the electronic device are provided. The electronic device includes a charging current receiver configured to receive a charging current, a voltage and current detector configured to monitor the charging current, and a controller configured to calculate an accumulated amount of charging power according to the monitoring of the charging current and to block battery charging when the accumulated amount of the charging power is greater than or equal to a power amount configured to perform a blocking operation.

Claims

1. An electronic device comprising:

a charging current receiver configured to receive a charging current;

a detector configured to monitor the charging current; and

a controller configured to calculate an accumulated amount of charging power according to the monitoring of the charging current and to block battery charging when the accumulated amount of the charging power is greater than or equal to a power amount configured to perform a blocking operation.

2. The electronic device of claim 1, further comprising:

a display unit configured to display full charging notification after the battery charging is blocked.

3. The electronic device of claim 1, wherein the controller performs an auxiliary charging process after the battery charging is blocked.

4. The electronic device of claim 1, wherein the detector monitors the charging current, converts a charging current value to an Analog-Digital Conversion (ADC) value, and provides the ADC value.

5. The electronic device of claim 1, wherein the controller blocks the battery charging when a battery voltage is greater than or equal to a full charging voltage.

6. The electronic device of claim 1, wherein the controller blocks the battery charging when an inflow current flowing into a battery is less than or equal to a cut-off current.

7. The electronic device of claim 1, wherein the controller terminates charging according to a charging termination request by a user.

8. A method of controlling charging in an electronic device, the method comprising:

receiving a charging current;

monitoring the charging current;

calculating an accumulated amount of charging power according to the monitoring of the charging current; and

controlling to block battery charging when the accumulated amount of the charging power is greater than or equal to a power amount configured to perform a blocking operation.

9. The method of claim 8, further comprising:

displaying a full charging notification after the battery charging is blocked.

10. The method of claim 8, further comprising:

performing an auxiliary charging process after the battery charging is blocked.

11. The method of claim 8, wherein the monitoring of the charging current comprises:

monitoring the charging current through a detector;

converting a charging current value to an Analog-Digital Conversion (ADC) value; and

providing the ADC value.

12. The method of claim 8, further comprising:

blocking the battery charging when a battery voltage is greater than or equal to a full charging voltage.

13. The method of claim 8, further comprising:

blocking the battery charging when an inflow current flowing into a battery is less than or equal to a cut-off current.

14. The method of claim 8, wherein the calculating of the accumulated amount of charging power comprises calculating a charging electric charge required for a full charging of a battery.

15. A non-transitory computer-readable storage medium storing instructions that, when executed, cause at least one processor to perform the method of claim 8.
