Abstract

A vehicle computer system includes a processor configured to receive a destination, to output a charging station location for display in response to an estimated SOC being less than a threshold and the location being within a pre-defined distance from a vehicle, and to not automatically output the location otherwise such that as a difference between the SOC and threshold increases, the pre-defined distance increases.

Claims

1. A vehicle computer system, comprising:

a wireless transceiver configured to communicate vehicle route information and vehicle battery information with a charging station; and

a processor configured to receive a destination, to output a charging station location for display in response to an estimated state of charge (SOC) is below a threshold and the charging station location being within a pre-defined distance from a vehicle route to the destination, wherein the pre-defined distance is defined by a user of a vehicle and is configured to automatically adjust based on the vehicle'"'"'s SOC, and to not automatically output the charging station location otherwise such that as the SOC is both below the threshold and the charging station location is further from the vehicle than the pre-defined distance, wherein the pre-defined distance is configured to automatically increase as the SOC increases.

2. The vehicle computer system of claim 1, wherein the vehicle route information includes at least the vehicle route to the destination, the destination, or a route preference.

3. The vehicle computer system claim 1, wherein the wireless transceiver is further configured to receive charging port information from the one or more charging stations, and wherein the processor is further configured to output a recommended charging port location in response to the vehicle battery information, vehicle route information, charging port information, and the estimated SOC at the destination.

4. The vehicle computer system of claim 3, wherein the charging port information includes at least one of charging port occupancy, charging port voltage, or charging port speed.

5. The vehicle computer system of claim 3, wherein the recommended charging port location is output utilizing voice recognition dialogue of the vehicle computer system.

6. The vehicle computer system of claim 1, wherein the wireless transceiver communicates to the charging station through an off-board server.

7. The vehicle computer system in a vehicle of claim 1, wherein the at least one charging station is within a pre-defined distance of a vehicle route.

8. The vehicle computer system of claim 1, wherein the vehicle battery information includes at least one of a SOC of the vehicle battery, a quick-charge capability of the vehicle battery, or a minimum charge requirement of the vehicle battery.

9. A system comprising:

a processor configured to automatically to send vehicle route and battery information to a selected charging station using a wireless transceiver and output a charging station locations on a vehicle display when a state of charge (SOC) of a vehicle battery is below a threshold and within a pre-defined distance of a vehicle route, wherein the pre-defined distance is user defined and configured to automatically increase based as the SOC increases.

10. The system of claim 9, wherein the wireless transceiver is further configured to receive charging port information from the selected charging station, and wherein the processor is further configured to receive user input requesting a recommended charging port location, and output the recommended charging port location in response to the charging port information and an estimated SOC at a destination of the vehicle route.

11. The system of claim 10, wherein the charging port information includes at least one of charging port occupancy, charging port voltage, or charging port speed.

12. The system of claim 10, wherein the recommended charging port location is output in response to the vehicle route information and vehicle battery information.

13. A method in a battery-electric vehicle, comprising:

automatically outputting a plurality of charging stations on a vehicle display in response to an estimate state of charge (SOC) of a battery being below a threshold and within a pre-defined distance of a vehicle route to a destination and not outputting the plurality of charging stations on the vehicle display in response to the estimate SOC being above the threshold, wherein the pre-defined distance is defined by a user of the battery-electric vehicle, wherein the pre-defined distance automatically increase as the SOC increases;

receiving input of a selected charging station selected from the plurality of charging stations;

sending vehicle route information and vehicle battery information to the selected station using a wireless transceiver.

14. The method of claim 13, further comprising receiving charging port information from the selected charging station, and outputting a recommended charging port location.

15. The method of claim 14, wherein the recommended charging port location is output utilizing vehicle speakers.

16. The method of claim 13, wherein the vehicle route information includes an estimated arrival time at the selected charging station.
