Abstract

A charging system is provided. The charging system includes: a charging stand for obtaining vehicle information from the vehicle and transmitting the obtained vehicle information to a management server, and supplying power to a battery equipped in the vehicle on the basis of the transmitted vehicle information; and the management server for determining a charging condition of the battery equipped in the vehicle by using the vehicle information transmitted through the charging stand, and transmitting charging information corresponding to the determined charging condition to the charging stand.

Claims

1. A charging system for charging a vehicle, the system comprising:

a charging stand for obtaining vehicle information from the vehicle, transmitting the obtained vehicle information to a management server, and supplying power to a vehicle battery according to the obtained vehicle information;

a Radio Frequency Identification (RFID) tag connected to the battery via a plurality of lines, one of the plurality of lines a power supply line for receiving driving power and another of the plurality of lines a detection line for detecting whether the RFID tag is separated from the battery; and

the management server for determining a charging condition of the battery by using the transmitted vehicle information, and transmitting charging information corresponding to the determined charging condition to the charging stand,

wherein the charging stand receives the transmitted charging information, and supplies power to the battery according to the corresponding charging condition,

wherein the vehicle information comprises separation history information according to whether the RFID tag was separated from the battery, and

wherein the separation history information is detected according to whether the detection line is connected or disconnected.

2. The charging system according to claim 1, wherein the vehicle information further comprises identification information for identifying the vehicle;

and

the charging stand obtains the identification information from the RFID tag.

3. The charging system according to claim 2, wherein the management server is further for:

determining whether the vehicle corresponds to a crackdown target by using the identification information and the separation history information; and

determining the charging condition according to the determination.

4. The charging system according to claim 3, wherein the management server comprises a database for storing the identification information.

5. The charging system according to claim 1, wherein the charging condition is at least a normal charging condition, a low speed charging condition, or no charging condition.

6. The charging system according to claim 5, wherein the charging stand is further for transmitting position information related to the vehicle to the management server if the charging condition is the low speed charging condition or the no charging condition.

7. A charging stand comprising:

a connection part having a plug for supplying power to a vehicle battery;

a Radio Frequency Identification (RFID) reading unit for obtaining vehicle information from the vehicle by communicating with an RFID tag attached to the battery;

a transmission unit for transmitting the obtained vehicle information to a management server; and

a control unit for controlling the transmission unit to transmit the obtained vehicle information, for receiving charging information according to whether the transmitted vehicle information is normal, and for charging the vehicle connected to the connection part according to a charging condition corresponding to the received charging information,

wherein the vehicle information comprises separation history information according to whether the RFID tag is separated from the battery, and

wherein the separation history information is used for determining whether the vehicle corresponds to a crackdown target according to whether the RFID tag was separated from the battery.

8. The charging stand according to claim 7, further comprising a switching unit for selectively cutting off power supplied to a battery in response to a control signal from the control unit.

9. The charging stand according to claim 7, wherein the vehicle information further comprises identification information related to the vehicle that is stored in the RFID tag.

10. The charging stand according to claim 7, wherein the charging information is at least a normal charging condition, a low speed charging condition, or a no charging condition;

and

the control unit is further for controlling a supply state of the power according to the charging condition.

11. The charging stand according to claim 10, wherein the control unit is further for transmitting position information related to the vehicle to the management server if the charging condition is the low speed charging condition of the no charging condition.

12. A method of charging a vehicle, the method comprising:

obtaining vehicle information from the vehicle;

determining whether the vehicle is a crackdown target by using the obtained vehicle information;

determining a charging condition of the vehicle according to the determination; and

supplying power to a vehicle battery according to the determined charging condition,.

wherein obtaining the vehicle information comprises obtaining separation history information according to whether a Radio Frequency IDentification (RFID) tag is separated from the battery.

13. The method according to claim 12, wherein obtaining the vehicle information further comprises obtaining identification information related to the vehicle from the RFID.

14. The method according to claim 13, wherein determining whether the vehicle is a crackdown target comprises:

determining whether the obtained identification information corresponds to the crackdown target by using previously-stored crackdown target identification information; and

determining whether the RFID tag was separated from the battery by using the obtained separation history information.

15. The method according to claim 12, wherein the charging condition is at least a normal charging condition, a low speed charging condition, or a no charging condition;

and

supplying the power comprises adjusting an amount of power supplied to the battery according to the charging condition or cutting off the supplied power.

16. The method according to claim 15, further comprising transmitting position information related to the vehicle externally if the charging condition is the low speed charging condition or the no charging condition.
