Abstract

Provided is an electric vehicle charging apparatus, and more particularly, an electric vehicle charging apparatus that periodically transmits a consumed amount of power to a cost claim server, so as to claim a cost per unit time. The charging apparatus includes a charging certification unit receiving certification information of the electric vehicle, a power measurement unit generating power consumption information as a result obtained by calculating an amount of power consumed for charging the electric vehicle, and a communication unit transmitting the certification information to a certification server, and transmitting the power consumption information to a cost claim server.

Claims

1. A charging apparatus for charging an electric vehicle, comprising:

a charging certification unit receiving certification information of the electric vehicle;

a power measurement unit generating power consumption information as a result obtained by calculating an amount of power consumed for charging the electric vehicle; and

a communication unit transmitting the certification information to a certification server, and transmitting the power consumption information to a cost claim server,

wherein when the communication unit transmits first power consumption information to the cost claim server, the power measurement unit generates second power consumption information,

wherein the first power consumption information comprises an amount of power supplied from the electric vehicle to a power grid located at an upper level for first unit time, and the second power consumption information comprises an amount of power supplied from the electric vehicle to the power grid for second unit time.

2. The charging apparatus according to claim 1, wherein the power consumption information comprises the amount of power consumed for charging the electric vehicle, and information about time consumed for charging the electric vehicle.

3. The charging apparatus according to claim 2, wherein the information about time consumed for charging the electric vehicle comprises at least one of information about time when use of power for charging the electric vehicle is started, and information about time when the use of power for charging the electric vehicle is ended.

4. The charging apparatus according to claim 1, wherein the communication unit transmits the power consumption information to the cost claim server at every unit time.

5. The charging apparatus according to claim 1, wherein when the communication unit transmits first power consumption information to the cost claim server, the power measurement unit generates second power consumption information,

wherein the first power consumption information comprises an amount of power consumed for charging the electric vehicle for first unit time, and the second power consumption information comprises an amount of power consumed for charging the electric vehicle for second unit time.

6. The charging apparatus according to claim 1, wherein the certification information comprises at least one of an identification (ID) of the electric vehicle and an ID of a user of the charging apparatus.

7. A method of charging an electric vehicle, comprising:

calculating an amount of power consumed for charging the electric vehicle, to generate power consumption information; and

transmitting the power consumption information to a cost claim server,

wherein the generating of the power consumption information corresponds to generating second power consumption information when first power consumption information is transmitted to the cost claim server,

wherein the first power consumption information comprises an amount of power supplied from the electric vehicle to a power grid located at an upper level for first unit time, and the second power consumption information comprises an amount of power supplied from the electric vehicle to the power grid for second unit time.

8. The method according to claim 7, wherein the power consumption information comprises the amount of power consumed for charging the electric vehicle, and information about time consumed for charging the electric vehicle.

9. The method according to claim 8, wherein the information about time consumed for charging the electric vehicle comprises at least one of information about time when use of power for charging the electric vehicle is started, and information about time when the use of power for charging the electric vehicle is ended.

10. The method according to claim 7, wherein the transmitting of the power consumption information to the cost claim server comprises transmitting the power consumption information to the cost claim server at every unit time.

11. The method according to claim 7, wherein the generating of the power consumption information corresponds to generating second power consumption information when first power consumption information is transmitted to the cost claim server,

wherein the first power consumption information comprises an amount of power consumed for charging the electric vehicle for first unit time, and the second power consumption information comprises an amount of power consumed for charging the electric vehicle for second unit time.

12. The method according to claim 7, further comprising:

receiving certification information of the electric vehicle; and

transmitting the certification information to a certification server.

13. The method according to claim 12, wherein the certification information comprises at least one of an identification (ID) of the electric vehicle and an ID of a user charging the electric vehicle.

14. A charging system for charging an electric vehicle, comprising:

a charging apparatus that generates power consumption information as a result obtained by calculating an amount of power consumed for charging the electric vehicle; and

a cost claim server that determines a charging cost corresponding to the power consumption information transmitted from the charging apparatus,

wherein, when the charging apparatus transmits first power consumption information to the cost claim server, the charging apparatus generates second power consumption information,

wherein the first power consumption information comprises at least one of an amount of power consumed for charging the electric vehicle for first unit time, and an amount of power supplied from the electric vehicle to a power grid located at an upper level for the first unit time, and

wherein the second power consumption information comprises at least one of an amount of power consumed for charging the electric vehicle for second unit time, and an amount of power supplied from the electric vehicle to the power grid for the second unit time.

15. The charging system according to claim 14, wherein the charging apparatus transmits the power consumption information generated at every unit time, to the cost claim server.

16. The charging system according to claim 14, further comprising a certification server that receives certification information transmitted from the charging apparatus to perform a certification process, and transmits a result of the certification process to the charging apparatus.

17. The charging system according to claim 16, wherein the certification information comprises at least one of an identification (ID) of the electric vehicle and an ID of a user of the charging apparatus.
