Electric vehicle range management

1. A method for managing range of an electric vehicle,

the method comprising:

parking the electric vehicle;

while the vehicle is parked, acquiring temperature forecast data for an upcoming time period, the upcoming time period longer than one instantaneous time;

determining a worst-case range of the electric vehicle over the upcoming time period in view of the temperature forecast data;

determining a driving distance from the electric vehicle to a stationary electric vehicle charging station; and

informing a user of the electric vehicle in the event that, at any time during the upcoming time period, the worst-case range of the electric vehicle will be less than a threshold relative to the driving distance from the electric vehicle to the stationary electric vehicle charging station.

2. The method of claim 1 , wherein the threshold is more than the driving distance from the electric vehicle to the stationary electric vehicle charging station.

3. The method of claim 1 , wherein acquiring temperature forecast data for an upcoming time period comprises:

acquiring temperature forecast data for the upcoming time period at a current location of the electric vehicle; and

acquiring temperature forecast data for the upcoming time period at a second location.

4. The method of claim 1 , wherein the stationary electric vehicle charging station is the closest stationary electrical vehicle charging station by driving distance to the electric vehicle.

5. The method of claim 1 , further comprising identifying to the user one or more mobile charging services in the event that the range of the electric vehicle will be less than the threshold.

6. The method of claim 1 , wherein the worst-case range includes a range reduction due to rising temperature.

7. The method of claim 1 , further comprising informing the user of a range boost that would be available through use of a Level 1 battery charger.

8. The method of claim 1 , wherein:

informing the driver comprises giving the driver a notice about insufficient range; and

the method further comprises placing a mobile charging order for the electric vehicle in the event that the driver ignores the notice.

9. A method for managing range of an electric vehicle, the method comprising:

while the electric vehicle is parked, acquiring temperature forecast data for an upcoming time period, the upcoming time period longer than one instantaneous time;

determining a worst-case range of the electric vehicle over the upcoming time period in view of the temperature forecast data;

determining a driving distance from the electric vehicle to a destination; and

informing a user of the electric vehicle in the event that, at one or more times during the upcoming time period, the worst-case range of the electric vehicle will be less than a threshold relative to the driving distance from the electric vehicle to the destination.

10. The method of claim 9 , wherein the threshold is more than the driving distance from the electric vehicle to the destination.

11. The method of claim 9 , wherein the destination is inferred from past trips driven by the user.

12. The method of claim 9 , further comprising identifying to the user of the electric vehicle locations of one or more stationary electric vehicle charging stations in the event that the range of the electric vehicle will be less than the threshold.

13. The method of claim 9 , further comprising identifying to the user one or more mobile electric vehicle charging services in the event that the range of the electric vehicle will be less than the threshold.

14. The method of claim 9 , wherein acquiring temperature forecast data for an upcoming time period comprises:

acquiring temperature forecast data for the upcoming time period at a current location of the electric vehicle; and

acquiring temperature forecast data for the upcoming time period at a second location.

15. A range management system for an electric vehicle, the system comprising one or more controllers collectively programmed with the following instructions:

while the electric vehicle is parked, acquire temperature forecast data for an upcoming time period, the upcoming time period longer than one instantaneous time;

determine a worst-case range of the electric vehicle over the upcoming time period in view of the temperature forecast data;

determine a driving distance from the electric vehicle to a destination; and

inform a user of the electric vehicle in the event that, at any time during the upcoming time period, the worst-case range of the electric vehicle will be less than a threshold relative to the driving distance from the electric vehicle to the destination.

16. The system of claim 15 , wherein the threshold is more than the driving distance from the electric vehicle to the destination.

17. The system of claim 15 , wherein the destination is inferred from past trips driven by the user.

18. The system of claim 15 , wherein the one or more controllers are further collectively programmed with the following instruction:

identify to the user of the electric vehicle locations of one or more stationary electric vehicle charging stations in the event that the range of the electric vehicle will be less than the threshold.

19. The system of claim 15 , wherein the one or more controllers are further collectively programmed with the following instruction:

identify to the user one or more mobile electric vehicle charging services in the event that the range of the electric vehicle will be less than the threshold.

20. The system of claim 15 , wherein the one or more controllers are further collectively programmed with the following instruction:

acquire temperature forecast data for the upcoming time period at a current location of the electric vehicle; and

acquire temperature forecast data for the upcoming time period at a second location.
