Abstract

An apparatus for controlling a battery of a green car, the apparatus includes an information collector configured to collect navigation information; a charge amount manager configured to manage a charge amount of the battery; a charger configured to charge the battery; and a controller configured to control the charging according to the charge amount of the battery and to expand a usable state of charge range of the battery based on the navigation information collected by the information collector.

Claims

1. An apparatus for controlling a battery of a green car, the apparatus comprising:

an information collector configured to collect navigation information;

a charge amount manager configured to manage a charge amount of the battery;

a charger configured to charge the battery; and

a controller configured to control the charging according to the charge amount of the battery and to expand a usable state of charge range of the battery based on the navigation information collected by the information collector.

2. The apparatus according to claim 1, wherein the information collector collects a scheduled time of arrival and road information.

3. The apparatus according to claim 2, wherein the controller expands the usable state of charge range to a primary usable state of charge range when the scheduled time of arrival exceeds a first threshold time.

4. The apparatus according to claim 3, wherein the controller controls the charger such that the battery is charged before the scheduled time of arrival using a second threshold time.

5. The apparatus according to claim 3, wherein the controller expands the primary usable state of charge range to a secondary usable state of charge range when the road information includes information that a road is a highway.

6. The apparatus according to claim 5, wherein the controller controls the charger such that the battery is charged before the scheduled time of arrival using a second threshold time.

7. The apparatus according to claim 1, wherein the charger is a low voltage DC-DC converter converting a high voltage of a high voltage battery into a charging voltage of the battery.

8. The apparatus according to claim 1, wherein the charger charges the battery with energy generated by regenerative braking.

9. A method for controlling a battery of a green car, the method comprising steps of:

collecting, by an information collector, navigation information;

expanding, by a controller, a usable state of charge range of the battery based on the collected navigation information; and

controlling, by the controller, a charging of the battery based on the expanded usable state of charge range.

10. The method according to claim 9, wherein the navigation information includes a scheduled time of arrival and road information.

11. The method according to claim 10, wherein in the step of expanding the usable state of charge range of the battery includes expanding the usable state of charge range to a primary usable state of charge range when the scheduled time of arrival exceeds a first threshold time.

12. The method according to claim 11, further comprising charging the battery for a second threshold time before the scheduled time of arrival.

13. The method according to claim 11, wherein in the step of expanding the usable state of charge range of the battery includes expanding the primary usable state of charge range to a secondary usable state of charge range when the road information includes a highway.

14. The method according to claim 13, further comprising charging the battery for a second threshold time before the scheduled time of arrival.
