Abstract

An electric vehicle charging control system includes a battery for operating the electric vehicle that is charged by a charging connection to a charging station. A user interface is associated with the electric vehicle and includes a display and a user input device. A communication system communicates with the charging station. The communication system receives a congestion signal from the charging station when a second electric vehicle is waiting for charging by the charging station. After the congestion signal is received, the user interface prompts an operator of the electric vehicle that the second electric vehicle is waiting for charging by the charging station.

Claims

1. An electric vehicle charging control system comprising:

a battery for operating the electric vehicle, the battery configured to be charged by a charging connection to a charging station;

a user interface associated with the electric vehicle, the user interface having a display and a user input device;

a communication system communicating with the charging station, the communication system receiving a congestion signal from the charging station when a second electric vehicle is waiting for charging by the charging station;

wherein, after the congestion signal is received, the user interface prompts an operator of the electric vehicle that the second electric vehicle is waiting for charging by the charging station.

2. The electric vehicle charging control system of claim 1, wherein the user interface prompts the operator with a prompt indicator on the display.

3. The electric vehicle charging control system of claim 2, wherein the prompt indicator is a selectable indicator allowing early cessation of charging.

4. The electric vehicle charging control system of claim 3, wherein the user input device allows the operator to either accept or deny early cessation of charging.

5. The electric vehicle charging control system of claim 1, wherein the user interface displays at least one of a current battery state of charge, a remaining charging time to complete charging, and a travel range based on the current battery state of charge on the display when the user interface prompts the operator.

6. The electric vehicle charging control system of claim 1, wherein the user interface is built into the electric vehicle.

7. The electric vehicle charging control system of claim 1, wherein the user interface is an electronic device removable from the electric vehicle.

8. The electric vehicle charging control system of claim 1, wherein a charging completion time for the electric vehicle is decreased after the congestion signal is received.

9. An electric vehicle charging control system comprising:

a battery for operating the electric vehicle, the battery configured to be charged by a charging connection to a charging station;

a user interface associated with the electric vehicle, the user interface having a display and a user input device;

a controller for controlling charging of the electric vehicle, the controller receiving a state of charge of the battery;

a communication system communicating with the charging station without establishing the charging connection with the charging station, the communication system receiving a billing signal from the charging station relating to a corresponding billing model used by the charging station;

wherein the controller calculates a charging cost based on the billing signal; and

wherein, after the billing signal is received, the controller determines a charging profile based on the charging cost determined based on the billing signal and at least one of an operator desired charging time and an operator desired post-charging battery state of charge, the charging profile being adjustable based on operator inputs to the user input device to change at least one of the charging time and the post-charging battery state of charge.

10. The electric vehicle charging control system of claim 9, wherein the communication system establishes in-vicinity wireless communication with the charging station.

11. The electric vehicle charging control system of claim 9, wherein the communication system establishes communication with the charging station based on a global positioning system of the electrical vehicle.

12. The electric vehicle charging control system of claim 9, wherein the billing signal comprises a billing rate.

13. The electric vehicle charging control system of claim 9, wherein the controller updates the charging cost as the operator adjusts at least one of the charging time and the post-charging battery state of charge.

14. The electric vehicle charging control system of claim 9, wherein the controller determines the charging profile based on at least one of a charge rate of the charging station and an operator desired travel distance.

16. The electric vehicle charging control system of claim 9, wherein the charging connection with the charging station is established after the charging profile is determined by the controller.

17. The electric vehicle charging control system of claim 9, wherein the communication system receives a congestion signal from the charging station when a second electric vehicle is waiting for charging by the charging station, the user interface prompting an operator of the electrical vehicle that the second electrical vehicle is waiting for charging by the charging station after the congestion signal is received.

15. The electric vehicle charging control system of claim 15, wherein the controller determines the travel distance based on a navigation system signal of the electrical vehicle.

18. An electric vehicle charging control system comprising:

a battery for operating the electric vehicle, the battery configured to be charged by a charging connection to a charging station;

wherein the controller calculates a full charging time based on the state of charge of the battery;

wherein the controller calculates a charging cost based on the at least one billing signal; and

wherein the controller determines a quick charge profile having a reduced charging time less than a full charging time based on the charging cost.

19. The electric vehicle charging control system of claim 18, wherein the controller has at least two acceptable billing signals corresponding to different billing models, the controller determining different quick charge profiles for the different acceptable billing signals.

20. The electric vehicle charging control system of claim 18, wherein the controller determines the quick charge profile based on at least one of an operator desired travel distance and a charge rate of the charging station.

21. The electric vehicle charging control system of claim 18, wherein the full charging time is adjustable based on operator inputs to the user input device to change an operator desired post-charging battery state of charge.

22. The electric vehicle charging control system of claim 18, wherein the controller is capable of receiving a bill-per-energy-unit billing signal and a bill-per-time-unit billing signal, the quick charge profile determined by the controller being based on a charge rate of the charging station.

23. The electric vehicle charging control system of claim 18, wherein the controller is capable of receiving a bill-per-energy-unit billing signal and a bill-per-time-unit billing signal, the quick charge profile determined by the controller for the bill-per-energy-unit billing signal being based on an operator desired travel distance, the quick charge profile determined by the controller for the bill-per-time-unit billing signal being based on a charge rate of the charging station.
