Abstract

A battery charging control apparatus of an electric vehicle includes an air conditioning control device that controls an operation of an air conditioning device, a control device that receives global positioning system (GPS) information of a user terminal, which approaches a vehicle, and to generate charging control information based on a distance that is determined based on the GPS information of the user terminal and location information of the vehicle, and a battery charging device that controls an amount of current to be supplied to a battery and the air conditioning control device, based on the charging control information.

Claims

1. A battery charging control apparatus of an electric vehicle comprising:

an air conditioning control device configured to control an operation of an air conditioning device;

a control device configured to receive global positioning system (GPS) information of a user terminal, which approaches a vehicle, and to generate charging control information based on a distance that is configured to be determined based on the GPS information of the user terminal and location information of the vehicle; and

a battery charging device configured to control an amount of current to be supplied to a battery and the air conditioning control device, based on the charging control information.

2. The battery charging control apparatus of claim 1, wherein the battery charging device is configured to determine a state of charge (SOC) of the battery and an estimated full-charging time by measuring an amount of charging current while the battery is charged, and transmits the determined result to the control device.

3. The battery charging control apparatus of claim 1, wherein the battery charging control apparatus is installed in the vehicle and communicates with a telematics server by using a communication device included in the vehicle.

4. The battery charging control apparatus of claim 1, wherein the control device generates the charging control information based on an approaching speed of the user terminal.

5. The battery charging control apparatus of claim 3, wherein the telematics server receives a remote control signal from the user terminal, wherein the telematics server remotely controls the air conditioning control device.

6. The battery charging control apparatus of claim 1, wherein as a distance determined based on the GPS information of the user terminal and the location information of the vehicle decreases, the control device increases an amount of current distributed to the air conditioning control device and decreases an amount of current distributed to the battery.

7. The battery charging control apparatus of claim 1, wherein as a speed at which the user terminal approaches the vehicle increases based on the GPS information of the user terminal and the location information of the vehicle, the control device increases an amount of current distributed to the air conditioning control device and decreases an amount of current distributed to the battery.

8. A battery charging control method, the method comprising:

receiving, by a control device, GPS information of a user terminal through a telematics server;

comparing the received GPS information of the user terminal with current location information of an own vehicle;

determining an approaching distance between a location of the received GPS information of the user terminal and a current location of the own vehicle; and

adjusting an amount of current to be supplied to a battery charging device and an air conditioning control device, based on the determined approaching distance.

9. The method of claim 8, further comprising:

before the receiving of the GPS information of the user terminal, waking up, by the telematics server, the control device when the telematics server receives GPS information of a user from the user terminal.

10. The method of claim 8, wherein the telematics server controls the air conditioning control device.

11. The method of claim 8, further comprising:

when the approaching distance between the location of the GPS information of the user terminal and the current location of the own vehicle is smaller than a distance, increasing an amount of current to be supplied to the air conditioning control device and decreasing an amount of current to be supplied to the battery charging device.

12. The method of claim 8, further including:

determining an approaching speed based on the GPS information of the user terminal and the current location information of the own vehicle; and

adjusting an amount of current to be supplied to the battery charging device and the air conditioning control device, based on the determined approaching speed.

13. The method of claim 12, further including:

increasing an amount of current supplied to the air conditioning control device and decreasing an amount of current supplied to the battery charging device, as the approaching speed at which the user terminal approaches the own vehicle increases based on the GPS information of the user terminal and the current location information of the own vehicle.
