Abstract

An energy management method and an energy management system are disclosed. The energy management method, according to one aspect of the present invention, comprises the steps of: collecting electric vehicle energy-related information from one or more electric vehicles; collecting power generation-related information from one or more new renewable energy power plants; and comparing the total amount of the collected power and a predicted amount of electric vehicle consumption to process a surplus energy or power amount.

Claims

1. A method for managing energy, comprising:

collecting electric vehicle (EV) energy related information from at least one EV;

gathering generation related information from at least one new renewable energy plant; and

processing a surplus power amount or generation amount by comparing a gathered overall generation amount with an anticipated EV consumption amount.

2. The method of claim 1, wherein the processing of the surplus power amount or generation amount includes transmitting the surplus power amount to an energy grid when the overall generation amount is greater than the anticipated EV consumption amount.

3. The method of claim 1, wherein the processing of the surplus power amount or generation amount includes storing the generation amount in a charging station or the EV when the overall generation amount is equal to or less than the anticipated EV consumption amount.

4. The method of claim 1, wherein the EV energy related information includes information about at least one of a driving location, a power consumption rate and remaining battery capacity of the EV.

5. The method of claim 1, wherein the generation related information includes information about at least one of an energy generation complex location, a charging station location, generation efficiency and an anticipated generation amount.

6. The method of claim 3, wherein the processing of the surplus power amount or generation amount further includes charging the EV according to a flexible fee priced according to at least one charge standard when the generation amount is stored in the EV.

7. The method of claim 1, wherein the charge standard includes at least one of a power consumption rate of the EV, a moving distance from the EV to a charging station, and remaining battery capacity of the EV.

8. The method of claim 1, further comprising:

detecting the EV that needs to be charged from the collected EV energy related information;

selecting a charging station for the EV that needs to be charged; and

transmitting information about the selected charging station to the EV that needs to be charged.

9. An energy managing system comprising:

an energy information collection part configured to collect electric vehicle (EV) energy related information from at least one EV;

a generation information collection part configured to gather generation related information from at least one new renewable energy plant; and

a control part configured to process a surplus power amount or generation amount by comparing a gathered overall generation amount with an anticipated EV consumption amount.

10. The energy managing system of claim 9, wherein the control part transmits the surplus power amount to an energy grid when the overall generation amount is greater than the anticipated EV consumption amount.

11. The energy managing system of claim 9, wherein the control part control a charging station or the EV to store the generation amount in the charging station or the EV when the overall generation amount is equal to or less than the anticipated EV consumption amount.

12. The energy managing system of claim 9, wherein the EV energy related information includes information about at least one of a driving location, a power consumption rate and remaining battery capacity of the EV.

13. The energy managing system of claim 9, wherein the generation related information includes information about at least one of a charging station location, generation efficiency and an anticipated generation amount.

14. The energy managing system of claim 9, wherein the control part charges the EV according to a flexible fee priced according to at least one charge standard when the generation amount is stored in the EV.

15. The energy managing system of claim 12, wherein the charge standard includes at least one of a power consumption rate of the EV, a moving distance from the EV to a charging station, and remaining battery capacity of the EV.

16. The energy managing system of claim 9, wherein the control part detects the EV that needs to be charged from the EV energy related information collected by the energy information collection part, selects a charging station for the EV that needs to be charged, and transmits information about the selected charging station to the EV that needs to be charged.

17. The energy managing system of claim 9, further comprising:

a database configured to store the EV energy related information and generation related information collected by the energy information collection part and the generation information collection part.

18. An electric vehicle (EV) comprising:

an energy information transmission part configured to periodically transmit EV energy related information to a data center; and

a charge control part configured to determine whether charging is needed based on remaining battery capacity information, transmit a charging guide request to the data center when the charging is needed, and receive a charging station guide message from the data center.

19. The EV of claim 18, wherein the EV energy related information includes information about at least one of a driving location, a power consumption rate and remaining battery capacity of the EV.
