Abstract

Systems and methods for determining availability of a vehicle charging station are provided. One vehicle system includes a telematics unit configured to wirelessly communicate with a second telematics unit of a second vehicle electrically coupled to a charging station; a processor configured to obtain a remaining charge time from the second vehicle, using the telematics unit; and a display for displaying the remaining charge time in association with information related to the second vehicle. One method includes establishing, using a telematics unit, wireless communication with a second telematics unit of a second vehicle electrically coupled to the charging station; obtaining, using a processor, a remaining charge time from the second vehicle via the telematics unit; and displaying, on a display, the remaining charge time in association with information related to the second vehicle.

First claim

The invention claimed is:

1. A vehicle system, comprising:
a telematics unit configured to wirelessly communicate with a second telematics unit of a second vehicle electrically coupled to a charging station;
a processor configured to obtain a remaining charge time from the second vehicle, using the telematics unit;
a display for displaying the remaining charge time in association with information related to the second vehicle; and
a user interface for receiving a user input associated with the displayed information, wherein in response to the user input, the processor prompts, via the user interface, entry of a message to an operator of the second vehicle, and the telematics unit sends the message to the second telematics unit for relay to a mobile communications device associated with the second vehicle.

2. The vehicle system of claim 1 , wherein the telematics unit is further configured to wirelessly communicate with the charging station, and the processor is further configured to obtain status information from the charging station using the telematics unit, and wherein the processor obtains a remaining charge time if the status information indicates an unavailability of the charging station.

3. The vehicle system of claim 2 , wherein the displayed information further includes the status information associated with the charging station.

4. The vehicle system of claim 1 , wherein in response to the user input, the display displays a map indicating a geographical location of the charging station.

5. The vehicle system of claim 1 , wherein the displayed information includes a user-selectable option to send a message to the operator of the second vehicle, and the user input includes selection of said option.

6. The vehicle system of claim 1 , wherein the message is a request for an estimated departure time of the second vehicle from the charging station.

7. The vehicle system of claim 6 , wherein the processor is further configured to receive a reply message from the second vehicle via the telematics unit, the reply message including the estimated departure time.

8. The vehicle system of claim 1 , wherein the telematics unit uses dedicated short-range communication to wirelessly communicate with the second telematics unit.

9. A method of determining availability of a vehicle charging station in a vehicle, comprising:
establishing, using a telematics unit, wireless communication with a second telematics unit of a second vehicle electrically coupled to the charging station;
obtaining, using a processor, a remaining charge time from the second vehicle via the telematics unit;
displaying, on a display, the remaining charge time in association with information related to the second vehicle;
receiving, via a user interface, a user input associated with the displayed information;
in response to receiving the user input, prompting, via the user interface, entry of a message to an operator of the second vehicle; and
sending, using the telematics unit, the message to the second telematics unit for relay to a mobile communications device associated with the second vehicle.

10. The method of claim 9 , further comprising:
obtaining status information from the charging station using the processor and the telematics unit, wherein the obtaining a remaining charge time occurs if the status information indicates an unavailability of the charging station.

11. The method of claim 10 , wherein the displayed information further includes the status information associated with the charging station.

12. The method of claim 9 , further comprising:
in response to receiving the user input, displaying, on the display, a map indicating a geographical location of the charging station.

13. The method of claim 9 , wherein the displayed information includes a user-selectable option to message the operator of the second vehicle, and the user input includes selection of said option.

14. The method of claim 9 , wherein the message is a request for an estimated departure time of the second vehicle from the charging station.

15. The method of claim 14 , further comprising:
receiving a reply message from the second vehicle via the telematics unit, the reply message including the estimated departure time.

16. The method of claim 9 , wherein the telematics unit uses dedicated short range communication to wirelessly communicate with the second telematics unit.

17. A vehicle comprising:
antennas;
a user interface; and
processors configured to:
obtain, from a second vehicle coupled to a charging station, information including a remaining charge time of the second vehicle;
responsive to receiving a user input associated with the information, prompt entry of a message to the second vehicle; and
send the message to the second vehicle for relay to a mobile device associated with the second vehicle.
