Abstract

The disclosure is related to managing a charging reservation of an electric vehicle. Particularly, the disclosure relates to managing an electric vehicle charging reservation based on at least one of a requested charging amount and a remaining battery power amount.

Claims

1. A method of managing an electric charging reservation for an electric vehicle charging, the method comprising:

receiving one or more charging reservation guide requests; and

performing a charging reservation guide procedure associated with the one or more charging reservation guide requests, based on at least one of a requested charging amount and a remaining battery power amount.

2. The method of claim 1, wherein the at least of the requested electric charging amount and the remaining battery power amount is received from each corresponding electric vehicle terminal.

3. The method of claim 1, wherein the performing includes:

transmitting a reservation disapproval message to a corresponding electric vehicle terminal when the requested charging amount included in each charging reservation guide request is lesser than a threshold value.

4. The method of claim 1, wherein the performing includes:

transmitting a reservation disapproval message to a corresponding electric vehicle terminal when the remaining battery power amount included in each charging reservation guide request is greater than a threshold value.

5. The method of claim 1, wherein in a case that two or more charging reservation guide requests are in a competition relationship for a same electric vehicle charging station, the performing includes:

determining a priority order between the two or more charging reservation guide requests, based on at least one of the requested charging amount and the remaining battery power amount.

6. The method of claim 5, wherein the priority order is in proportion to the requested charging amount, and is in inverse proportion to the remaining battery power amount.

7. The method of claim 5, wherein the remaining battery power amount is a battery power amount remaining at a time that a corresponding electric vehicle arrives at the same electric vehicle charging station.

8. The method of claim 5, wherein the performing includes:

obtaining electric charger state information of the same electric vehicle charging station, from an electric charging management system;

obtaining the number of available electric chargers from the electric charger state information;

determining a charging reservation sequence between the two or more charging reservation guide requests, based on the number of available electric chargers; and

providing charging reservation guide information including the charging reservation sequence, to each corresponding electric vehicle terminal.

9. The method of claim 8, wherein the charging reservation guide information further includes at least one of a predicted required driving time, a required charging time, and a predicted waiting time for electric charging.

10. A method of providing reservation guide information for an electric vehicle charging, the method comprising:

detecting an entry of an electric vehicle to a range of a specific electric vehicle charging station;

determining whether the electric vehicle can receive a charging service at a time when the electric vehicle arrives at the specific electric vehicle charging station; and

providing charging reservation guide information to a corresponding electric vehicle terminal when the electric vehicle can receive the charging service.

11. The method of claim 10, wherein the detecting includes:

obtaining location information of the electric vehicle from the corresponding electric vehicle terminal; and

determining whether the electric vehicle is within a range of the specific electric vehicle charging station, based on the location information.

12. The method of claim 10, wherein the determining includes:

obtaining a remaining battery power amount of the electric vehicle from the corresponding electric vehicle terminal;

obtaining electric charger state information of the specific electric vehicle charging station;

determining an available start time associated with one or more electric chargers, based on the electric charger state information; and

determining whether the electric vehicle can arrive at the specific electric vehicle charging station, before the available start time of the one or more electric chargers.

13. The method of claim 12, wherein the available start time is a time when the one or more electric chargers can be available.

14. The method of claim 12, wherein the determining whether the electric vehicle can arrive at the specific electric vehicle charging station includes:

determining whether the electric vehicle can arrive at the specific electric vehicle charging station, based on the remaining battery power amount and the location information of the electric vehicle.

15. The method of claim 12, wherein:

the electric charger state information includes charging schedule information; and

the charging reservation guide information includes at least one of the available start time, a predicted required driving time, and a predicted waiting time for an electric charging.

16. A method of providing reservation alarm information for an electric vehicle charging, the method comprising:

determining whether a remaining battery power amount of an electric vehicle is lesser than a threshold value;

determining one or more electric vehicle charging stations reachable by the electric vehicle when the remaining battery power amount of an electric vehicle is lesser than the threshold value; and

providing electric charging alarm information to a corresponding electric vehicle terminal.

17. The method of claim 16, wherein the remaining battery power amount is obtained from the corresponding electric vehicle terminal.

18. The method of claim 16, wherein the determining one or more electric vehicle charging stations includes:

determining the one or more electric vehicle charging stations at which the electric vehicle can arrive, based on the remaining battery power amount and location information of the electric vehicle.

19. The method of claim 16, further comprising:

obtaining electric charger state information associated with the reachable one or more electric vehicle charging stations, wherein the electric charger state information is employed for creation of the electric charging alarm information.

20. The method of claim 16, wherein the electric charging alarm information include at least one of a predicted required driving time, and a predicted waiting time for electric charging.
