Abstract

An electric vehicle is provided. A driver can remotely monitor battery charging associated operations and control a necessary function, thereby improving convenience of the driver of the electric vehicle.

Claims

1. A telematics device of an electric vehicle, comprising:

a battery management unit configured to measure a battery charging state and to output battery charging information;

a wireless communication unit configured to transmit and receive data according to a predefined communication protocol; and

a control unit configured to receive the battery charging information from the battery management unit when the battery is charged and to transmit the battery charging information to a predetermined server through the wireless communication unit.

2. The telematics device according to claim 1, wherein the battery management unit measures a charging current amount, computes a State of Charge (SOC) of the battery, and a charging completion time, and outputs the computed results to the control unit.

3. The telematics device according to claim 1, wherein the battery management unit transmits a charging start signal to the control unit when the charging of the battery is started and outputs a charging end signal to the control unit if the charging of the battery is finished.

4. The telematics device according to claim 3, wherein, if the charging start signal or the charging end signal is received, the control unit transmits the charging start signal or the charging end signal to the server.

5. The telematics device according to claim 1, wherein the battery management unit outputs an alarm signal indicating that the charging of the battery is impossible to the control unit.

6. The telematics device according to claim 1, wherein the control unit computes a travelable distance corresponding to a charging amount and transmits information about the computed travelable distance and the battery charging information.

7. The telematics device according to claim 6, wherein, if destination information is received, the control unit computes a distance to the destination, compares the computed distance with the travelable distance, and stops a charging operation of the battery management unit if the battery is charged by the amount of power necessary for traveling to the destination.

8. The telematics device according to claim 6, wherein, If destination information is received, the control unit compares a distance to the destination received from the server with the travelable distance, and stops a charging operation of the battery management unit if the battery is charged by the amount of power necessary for traveling to the destination.

9. The telematics device according to claim 1, wherein, if charging reservation information is set, the control unit stops the charging of the battery management unit until reaching a reserved time.

10. A method of providing a remote charging control service of an electric vehicle, the method comprising:

acquiring battery charging information when a battery is charged;

computing travelable distance according to the battery charging information; and

transmitting the battery charging information and information about the travelable distance to a predetermined sever.

11. The method according to claim 10, further comprising transmitting an alarm signal to the server, when a situation in which the charging of the battery is impossible occurs.

12. The method according to claim 10, wherein the acquiring of the battery charging information includes measuring a charging current amount, and computing a State of Charge (SOC) of the battery, and a charging completion time.

13. The method according to claim 10, wherein the acquiring of the battery charging information includes checking whether charging reservation information is present before the charging of the battery, and starting the charging of the battery when reaching a reserved time, if the charging reservation information is present.

14. The method according to claim 10, wherein the computing of the travelable information includes computing the travelable distance using predetermined mileage information and charging amount information of the charging information.

15. The method according to claim 10, further comprising, if destination information is received, comparing a distance to the destination with the travelable distance and charging the battery by the amount of power necessary for traveling to the destination.
