Abstract

An embodiment system for charging an electric motor vehicle includes a first switching circuit configured to select one of at least two chargers, a second switching circuit configured to select a charging station connector to be connected to the charger selected by the first switching circuit, and a controller configured to control the first switching circuit and the second switching circuit based on a predetermined charging order to allow charging of a battery of a vehicle that is connected to the charging station connector to be performed, sense connection of a charging connector of the vehicle to the charging station connector, receive a required charging amount and an available waiting time of the vehicle, and determine the charging order based on the required charging amount and the available waiting time.

First claim

What is claimed is:

1. A system for charging an electric motor vehicle, the system comprising:
a first switching circuit configured to select one of a plurality of chargers;
a second switching circuit configured to select a charging station connector to be connected to the charger selected by the first switching circuit; and
a controller configured to:
control the first switching circuit and the second switching circuit based on a predetermined charging order to allow charging of a battery of a vehicle that is connected to the charging station connector to be performed;
sense connection of a charging connector of the vehicle to the charging station connector;
receive a required charging amount and an available waiting time of the vehicle;

determine the charging order based on the required charging amount and the available waiting time of each vehicle; and
supply charging power to each vehicle based on the determined charging order.

2. The system of claim 1 , wherein the available waiting time is a time from a charging request time point to a desired charging completion time point.

3. The system of claim 1 , wherein the controller is configured to consider whether waiting delay is allowed for the vehicle when determining the charging order.

4. The system of claim 1 , wherein the controller is configured to pay compensation points to the vehicle that has the charging order changed to a lower priority.

5. The system of claim 1 , wherein the controller is configured to deduct predetermined points from the vehicle that has the charging order changed to a higher priority.

6. The system of claim 1 , wherein the controller is configured to determine an expected charging start time, an expected charging completion time, and a power distribution location based on a charger distribution status.

7. The system of claim 6 , wherein the controller is configured to control the first switching circuit and the second switching circuit based on the power distribution location to form a charging power supply path.

8. The system of claim 1 , wherein the controller is configured to flexibly adjust the charging order of the vehicle within the available waiting time.

9. A method for charging an electric motor vehicle using a charging system including a first switching circuit for selecting one of at least two chargers, a second switching circuit for selecting a charging station connector to be connected to the charger selected by the first switching circuit, and a controller configured to control the first switching circuit and the second switching circuit, the method comprising:
sensing a connection to the charging station connector by a charging connector of a vehicle that has requested charging;
receiving a required charging amount and an available waiting time of the vehicle that has requested the charging;
determining a charging order of the vehicle that has requested the charging based on the required charging amount and the available waiting time of each vehicle; and
controlling the first switching circuit and the second switching circuit based on the charging order to perform charging of a battery of the vehicle that has requested the charging.

10. The method of claim 9 , wherein the available waiting time is a time from a charging request time point to a desired charging completion time point.

11. The method of claim 9 , wherein determining the charging order of the vehicle that has requested the charging comprises determining the charging order by considering whether waiting delay is allowed for the vehicle that has requested the charging.

12. The method of claim 9 , wherein determining the charging order of the vehicle that has requested the charging further comprises paying compensation points to the vehicle that has the charging order changed to a lower priority.

13. The method of claim 9 , wherein determining the charging order of the vehicle that has requested the charging further comprises deducting predetermined points from the vehicle that has the charging order changed to a higher priority.

14. The method of claim 9 , wherein determining the charging order of the vehicle that has requested the charging further comprises determining an expected charging start time, an expected charging completion time, and a power distribution location based on a charger distribution status.

15. The method of claim 14 , wherein performing the charging of the battery of the vehicle that has requested the charging comprises controlling the first switching circuit and the second switching circuit based on the power distribution location to form a charging power supply path.

16. A system for charging electric motor vehicles, the system comprising:
a first charger configured to supply power to a plurality of first charging station connectors connected to the first charger;
a second charger configured to supply power to a plurality of second charging station connectors connected to the second charger;
a first switching circuit configured to select the first charger or the second charger;
a second switching circuit configured to select one of the first charging station connectors connected to the first charger or one of the second charging stations connected to the second charger based on the selection of the first charger or the second charger by the first switching circuit; and
a controller configured to:
control the first switching circuit and the second switching circuit to allow charging of batteries of vehicles that are connected to respective ones of the first and second charging station connectors;
sense connection of a charging connector of each of the vehicles to a respective one of the first and second charging station connectors;
receive a required charging amount, an available waiting time, and whether a waiting delay is allowed for each of the vehicles connected to the first and second charging station connectors;
determine a charging order of the vehicles based on the required charging amounts, the available waiting times, and whether the waiting delay is allowed; and
supply charging power to the vehicles based on the determined charging order.

17. The system of claim 16 , wherein the available waiting time is a time from a charging request time point to a desired charging completion time point.

18. The system of claim 16 , wherein in determining the charging order of the vehicles, the controller is configured to:
lower a priority of one of the vehicles and pay compensation points to the one of the vehicles; and
raise a priority of another of the vehicles and deduct a predetermined number of points from the other of the vehicles.

19. The system of claim 16 , wherein the controller is configured to determine an expected charging start time, an expected charging completion time, and a power distribution location based on a charger distribution status.

20. The system of claim 19 , wherein the controller is configured to control the first switching circuit and the second switching circuit based on the power distribution location to form a charging power supply path.
