Abstract

An apparatus and method for charging a battery are provided. The apparatus includes a controller that is configured to select a driving mode based on a user operation. In addition, a BMS (Battery Management System) is configured to execute a charge type based on the selected driving mode and charge the battery.

Claims

1. An apparatus for charging a battery, comprising:

a controller configured to select a driving mode based on a user operation;

a Battery Management System (BMS) configured to execute a charge type based on the selected driving mode; and

a battery configured to be charged based on a control of the BMS,

wherein when the driving mode is a short-distance driving mode, the charge is controlled to be performed up to a low state of charge (SOC).

2. The apparatus of claim 1, wherein the charge type is a high SOC charge in which, when the driving mode is not the short-distance driving mode, the charge is performed up to the high SOC, wherein the high SOC is 95% of full SOC.

3. The apparatus of claim 1, wherein the charge type is the low SOC charge in which, when the driving mode is the short-distance driving mode, the charge is performed up to the low SOC, wherein the low SOC is 80% of full SOC.

4. The apparatus of claim 2, wherein the high SOC charge charging with a predetermined low current up to the high SOC at a slow charge or charging with the predetermined high current up to the low SOC until reaching a threshold level and then charging with the predetermined low current up to the high SOC with respect to the remaining portion at a quick charge.

5. The apparatus of claim 1, wherein the low SOC charge is charging with a predetermined low current up to the low SOC at a slow charge or quick charging with predetermined high current up to the low Soc at a quick charge.

6. The apparatus of claim 1, wherein the controller is configured to store a driving distance and a charge type for a period of time and calculate a plurality of driving patterns from the stored data to calculate an optimal SOC.

7. The apparatus of claim 1, wherein a number of a charge or a charge amount based on the charge type is user set.

8. The apparatus of claim 4, wherein the quick charge is performed at the predetermined high current up to the low SOC until reaching a threshold level and is then performed at the predetermined low current up to the high SOC with respect to the remaining portion.

9. A method of charging a battery, comprising:

selecting, by a controller, a driving mode based on a user operation;

executing, by a battery management system (BMS) a charge type based on the selected driving mode; and

charging, by the BMS, the battery,

wherein when the driving mode is a short-distance driving mode, the charge is controlled to be performed up to a low state of charge (SOC).

10. The method of claim 9, wherein the charge type is a high SOC charge in which, when the driving mode is not the short-distance driving mode, the charge is performed up to the high SOC, wherein the high SOC is 95% of full SOC.

11. The method of claim 9, wherein the charge type is a low SOC charge in which, when the driving mode is the short-distance driving mode, the charge is performed up to the low SOC, wherein the low SOC is 80% of full SOC.

12. The method of claim 10, wherein the high SOC charge is charging with a predetermined low current up to the high SOC at a slow charge or charging with the predetermined high current up to the low SOC until reaching a threshold level and then charging with the predetermined low current up to the high SOC with respect to the remaining portion at a quick charge.

13. The method of claim 11, wherein the low SOC charge is charging with a predetermined low current up to the low SOC at a slow charge or charging with a predetermined high current up to the low SOC at a quick charge.

14. The method of claim 9, further comprising:

storing, by the controller, a driving distance and a charge type for a period of time; and

calculating, by the controller, a plurality of driving patterns from the stored data to calculate an optimal SOC.

15. The method of claim 9, wherein a number of a charge or a charge amount based on the charge type is user set.

16. The method of claim 12, wherein the quick charge is performed at the predetermined high current up to the low SOC until reaching a certain threshold and is then performed at the predetermined low current up to the high SOC with respect to the remaining portion.

17. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that select a driving mode based on a user operation;

program instructions that control a battery management system (BMS) to execute a charge type based on the selected driving mode; and

program instructions that control the BMS to charge the battery,

wherein when the driving mode is a short-distance driving mode, the charge is controlled to be performed up to a low state of charge (SOC).

18. The non-transitory computer readable medium of claim 17, wherein the charge type is a high SOC charge in which, when the driving mode is not the short-distance driving mode, the charge is performed up to the high SOC, wherein the high SOC is 95% of full SOC.

19. The non-transitory computer readable medium of claim 17, wherein the charge type is a low SOC charge in which, when the driving mode is the short-distance driving mode, the charge is performed up to the low SOC, wherein the low SOC is 80% of full SOC.

20. The non-transitory computer readable medium of claim 17, further comprising:

program instructions that store the driving distance and the charge type for a period of time; and

program instructions that calculate a plurality of driving patterns from the stored data to calculate an optimal SOC.
