Abstract

A system and method for creating a charging schedule for an electric vehicle that include determining a current state of charge of the electric vehicle. The system and method also include determining an average price per kilowatt-hour of energy to charge the electric vehicle to reach at least one of: a target state of charge of the electric vehicle and a maximum state of charge of the electric vehicle. The system and method further include creating the charging schedule based on the current state of charge and the average price per kilowatt-hour of energy.

First claim

The invention claimed is:

1. A computer-implemented method for creating a charging schedule for an electric vehicle, comprising:
determining a current state of charge of the electric vehicle, wherein determining the current state of charge includes determining if the current state of charge is above at least one of: a minimum state of charge of the electric vehicle and a target state of charge of the electric vehicle;
determining an average price per kilowatt-hour of energy to charge the electric vehicle to reach at least one of: the target state of charge and a maximum state of charge of the electric vehicle;
creating the charging schedule based on the current state of charge and the average price per kilowatt-hour; and
controlling charging of the electric vehicle to reach the minimum state of charge upon determining that the current state of charge is below the minimum state of charge and controlling charging of the electric vehicle to reach the maximum state of charge upon determining that the current state of charge is above the target state of charge.

2. The computer-implemented method of claim 1 , further including determining the target state of charge, wherein determining the target state of charge includes determining a driving profile of the electric vehicle, wherein the driving profile of the electric vehicle includes a profile of at least one of: an average distance the electric vehicle is driven during at least one specific timeframe, and an average time the electric vehicle is driven during the at least one specific timeframe.

3. The computer-implemented method of claim 2 , wherein determining the target state of charge includes evaluating the driving profile of the electric vehicle and determining the target state of charge, wherein the target state of charge is dynamic and is based on the driving profile.

4. The computer-implemented method of claim 1 , wherein creating the charging schedule includes creating the charging schedule to reach the target state of charge, wherein creating the charging schedule to reach the target state of charge includes determining one or more charging intervals based on at least one price threshold and a driving profile of the electric vehicle.

5. The computer-implemented method of claim 4 , wherein creating the charging schedule includes determining if the average price per kilowatt-hour of energy to charge the electric vehicle to the maximum state of charge is less than the average price per kilowatt-hour of energy to charge the electric vehicle to the target state of charge.

6. The computer-implemented method of claim 5 , wherein creating the charging schedule includes controlling charging of the electric vehicle to reach the target state of charge based on the charging schedule to reach the target state of charge upon determining that the average price per kilowatt-hour of energy to charge the electric vehicle to the maximum state of charge is more than the average price per kilowatt-hour of energy to charge the electric vehicle to the target state of charge.

7. The computer-implemented method of claim 5 , wherein creating the charging schedule includes creating the charging schedule to reach the maximum state of charge upon determining that the average price per kilowatt-hour of energy to charge the electric vehicle to the maximum state of charge is less than the average price per kilowatt-hour of energy to charge the electric vehicle to the target state of charge.

8. The computer-implemented method of claim 7 , wherein creating the charging schedule includes controlling charging of the electric vehicle to reach the maximum state of charge based on the charging schedule to reach the maximum state of charge.

9. A system for creating a charging schedule for an electric vehicle, comprising:
a memory storing instructions when executed by a processor cause the processor to:
determine a current state of charge of the electric vehicle, wherein determining the current state of charge includes determining if the current state of charge is above at least one of: a minimum state of charge of the electric vehicle and a target state of charge of the electric vehicle;
determine an average price per kilowatt-hour of energy to charge the electric vehicle to reach at least one of: the target state of charge and a maximum state of charge of the electric vehicle; and
create the charging schedule based on the current state of charge and the average price per kilowatt-hour; and
control charging of the electric vehicle to reach the minimum state of charge upon determining that the current state of charge is below the minimum state of charge and controlling charging of the electric vehicle to reach the maximum state of charge upon determining that the current state of charge is above the target state of charge.

10. The system of claim 9 , further including determining the target state of charge, wherein determining the target state of charge includes determining a driving profile of the electric vehicle, wherein the driving profile of the electric vehicle includes a profile of at least one of: an average distance the electric vehicle is driven during at least one specific timeframe, and an average time the electric vehicle is driven during the at least one specific timeframe.

11. The system of claim 10 , wherein determining the target state of charge includes evaluating the driving profile of the electric vehicle and determining the target state of charge, wherein the target state of charge is dynamic and is based on the driving profile.

12. The system of claim 9 , wherein creating the charging schedule includes creating the charging schedule to reach the target state of charge, wherein creating the charging schedule to reach the target state of charge includes determining one or more charging intervals based on at least one price threshold and a driving profile of the electric vehicle.

13. The system of claim 12 , wherein creating the charging schedule includes determining if the average price per kilowatt-hour of energy to charge the electric vehicle to the maximum state of charge is less than the average price per kilowatt-hour of energy to charge the electric vehicle to the target state of charge.

14. The system of claim 13 , wherein creating the charging schedule includes controlling charging of the electric vehicle to reach the target state of charge based on the charging schedule to reach the target state of charge upon determining that the average price per kilowatt-hour of energy to charge the electric vehicle to the maximum state of charge is more than the average price per kilowatt-hour of energy to charge the electric vehicle to the target state of charge.

15. The system of claim 13 , wherein creating the charging schedule includes creating the charging schedule to reach the maximum state of charge upon determining that the average price per kilowatt-hour of energy to charge the electric vehicle to the maximum state of charge is less than the average price per kilowatt-hour of energy to charge the electric vehicle to the target state of charge.

16. The system of claim 15 , wherein creating the charging schedule includes controlling charging of the electric vehicle to reach the maximum state of charge based on the charging schedule to reach the maximum state of charge.

17. A non-transitory computer readable storage medium storing instructions that, when executed by a computer, which includes at least a processor, causes the computer to perform a method, the method comprising:
determining a current state of charge of an electric vehicle, wherein det
