Abstract

A method of charging the battery of the vehicle includes starting charging of the battery; starting operation of an air conditioner using power supplied from the battery; and reducing an operation amount of the air conditioner while charging the battery and operating the air conditioner, thereby shortening the time required for charging the battery.

Claims

1. A method of charging a battery of a vehicle, comprising:

starting charging of the battery;

starting operation of an air conditioner using power supplied from the battery; and

reducing an operation amount of the air conditioner while charging the battery and operating the air conditioner, thereby shortening the time required for charging the battery.

2. The method according to claim 1, wherein the battery is charged up to a target charge amount required for the vehicle to travel to a destination.

3. The method according to claim 1, wherein the operation amount of the air conditioner is reduced by adjustment of a set temperature of the air conditioner.

4. The method according to claim 3, wherein the adjustment of the set temperature of the air conditioner comprises:

calculating a possible charging time from a difference between a scheduled departure time and a current time;

calculating a total amount of supplying power from a product of a charge power per hour and the possible charging time;

calculating an amount of available supply power for the air conditioner from a difference between the total amount of supplying power and a required battery charging amount; and

calculating a new set temperature of the air conditioner capable of charging the battery before the scheduled departure time, wherein the new set temperature of the air conditioner is calculated from the amount of available supply power.

5. The method according to claim 1, wherein the charging of the battery and the operation of the air conditioner are performed in response to a charging command and an air conditioning operation command that occurs before the scheduled time of the vehicle.

6. A vehicle, comprising:

a battery;

an air conditioner operated by power supplied from the battery; and

a controller reducing an operation amount of the air conditioner while charging the battery and operating the air conditioner, thereby shortening the time required for charging the battery.

7. The vehicle according to claim 6, wherein the battery is charged up to a target charge amount required for the vehicle to travel to a destination.

8. The vehicle according to claim 6, wherein the operation amount of the air conditioner is reduced by adjustment of a set temperature of the air conditioner.

9. The vehicle according to claim 8, wherein the controller is configured to:

calculate a possible charging time from a difference between a scheduled departure time and a current time;

calculate a total amount of supplying power from a product of a charge power per hour and the possible charging time;

calculate an amount of available supply power for the air conditioner from a difference between the total amount of supplying power and a required battery charging amount;

calculate a new set temperature of the air conditioner capable of charging the battery before the scheduled departure time, wherein the new set temperature of the air conditioner is calculated from the amount of available supply power; and

adjust the set temperature of the air conditioner based on the new set temperature of the air conditioner.

10. The vehicle according to claim 6, wherein the charging of the battery and the operation of the air conditioner are performed in response to a charging command and an air conditioning operation command that occurs before the scheduled time of the vehicle.

11. A method of charging a battery of a vehicle, comprising:

receiving a scheduled driving time and a destination of the vehicle, and a set temperature of the air conditioner;

displaying a present charge amount of the battery and the set temperature of the air conditioner on a display;

displaying a new set temperature of the air conditioner on the display, wherein the new set temperature of the air conditioner is for charging the battery up to a target amount of charge required for the vehicle to travel to the destination before the scheduled time of the vehicle during charging of the battery and operation of the air conditioner, thereby shortening the time required for charging the battery, and

controlling the charging of the battery so that the battery is charged to the target charging amount before the scheduled driving time of the vehicle while operating the air conditioner to follow the new set temperature of the air conditioner displayed on the display.

12. The method according to claim 11, wherein the scheduled driving time and destination of the vehicle and the set temperature of the air conditioner are set by a user of the vehicle through a mobile device.

13. The method according to claim 11, wherein the scheduled driving time and destination of the vehicle are received from a schedule guidance service based on wired communication or wireless communication.

14. The vehicle according to claim 11, wherein the set temperature of the air conditioner is acquired by analyzing the use history of the air conditioner.

15. The method according to claim 11, wherein the set temperature of the air conditioner is acquired by analyzing the weather history of a departure area of the vehicle.

16. The vehicle according to claim 11, wherein the battery is charged up to a target charge amount necessary for the vehicle to travel to a destination.

17. The vehicle according to claim 11, wherein the charging of the battery and the operation of the air conditioner are performed in response to a charging command and an air conditioning operation command that occurs before the scheduled time of the vehicle.

18. The method according to claim 11, further comprising obtaining approval from a user of the vehicle to change the set temperature of the air conditioner to the new set temperature of the air conditioner.

19. The method according to claim 18, further comprising generating an alarm to inform the user that the amount of charge of the battery may be insufficient, when the user'"'"'s approval for changing the new set temperature of the air conditioner is not obtained.
