Abstract

A controller may, after receiving indication that an electric utility provider will reduce power supplied during an upcoming period of time, increase a cost of charge energy for vehicles that charge at a rate at least equal to a threshold rate during the upcoming period of time. The controller may also decrease the cost of charge energy for vehicles that avoid charging or charge at a rate less than the threshold rate during the upcoming period of time.

First claim

What is claimed is:

1. A system comprising:
a controller programmed to, after receiving indication that an electric utility provider will reduce power produced during an upcoming duration of time, increase a cost of charge energy for vehicles that charge at a rate at least equal to a threshold rate during the upcoming duration of time, and request that the electric utility provider shorten the upcoming duration of time during which the power produced will be reduced based on data from the vehicles.

2. The system of claim 1 , wherein the controller is further programmed to request that the electric utility provider alter a start of the upcoming duration of time.

3. The system of claim 2 , wherein the data includes an indication as to whether the vehicles will charge at a rate less than the threshold rate or avoid charging during the upcoming duration of time.

4. The system of claim 1 , wherein the controller is further programmed to request that the vehicles alter a charge start time to avoid charging during at least a portion of the upcoming duration of time.

5. The system of claim 1 , wherein the controller is further programmed to, responsive to receiving, from the electric utility provider, a message specifying a time and location, estimate an energy saving commitment for the time and location using historical electronic charging data of the vehicles, and receive a payment from the electric utility provider, wherein an amount of the payment is based on implementation of the energy saving commitment.

6. The system of claim 5 , wherein the controller is further programmed to receive a bid from one of the vehicles, and further estimate the energy saving commitment using the bid.

7. The system of claim 5 , wherein the controller is further programmed to distribute a reward to the vehicles and wherein the reward corresponds to an energy saving of each vehicle for the time and location.

8. The system of claim 1 , wherein an amount of the increase depends on the rate.

9. The system of claim 1 , wherein the controller is further programmed to decrease the cost of charge energy for vehicles that charge at a rate less than the threshold rate or avoid charging during the upcoming duration of time.

10. The system of claim 9 , wherein an amount of the decrease depends on the rate.

11. The system of claim 1 , wherein the threshold rate is defined by the electric utility provider.

12. A system comprising:
a controller programmed to, responsive to an indication that an electric utility provider will reduce power supplied during an upcoming period of time, request that the electric utility provider alter a start or duration of the upcoming period of time based on data indicating whether vehicles scheduled to charge during the upcoming period of time will reduce a rate of charging.

13. The system of claim 12 , wherein the controller is further programmed to, request that the vehicles alter a charge start time to avoid charging during at least a portion of the upcoming period of time.

14. A method comprising:
decreasing a cost of charge energy for vehicles that avoid charging or charge at a rate less than a threshold rate during an upcoming duration of time after receiving indication that an electric utility provider will reduce power produced during the upcoming duration of time; and
requesting that the electric utility provider alter the duration of time during which the power produced will be reduced.

15. The method of claim 14 , requesting that the electric utility provider alter a start of the upcoming duration of time based on data from the vehicles.

16. The method of claim 15 , wherein the data includes an indication as to whether the vehicles will charge at a rate less than the threshold rate or avoid charging during the upcoming duration of time.

17. The method of claim 14 , requesting that the vehicles alter a charge start time to avoid charging during at least a portion of the upcoming duration of time.

18. The method of claim 14 , wherein an amount of the decrease depends on the rate.

19. The method of claim 14 further comprising increasing the cost of charge energy for vehicles that charge at a rate at least equal to the threshold rate during the upcoming duration of time.

20. The method of claim 19 , wherein an amount of the decrease depends on the rate.
