Abstract

A vehicle-grid integration management system determines use of a power grid by an electric vehicle in a dual multi-part rate structure including a grid account portion associated with a relationship between the electric vehicle and the power grid, a group account portion associated with a relationship between the vehicle group and the electric vehicle and/or the power grid, a consumption portion associated with a volume of electricity drawn from the power grid by the electric vehicle over a time period, a supply portion associated with a volume of electricity delivered to the power grid by the electric vehicle over the time period, a demand portion associated with an upper threshold of electricity drawn from the power grid by the electric vehicle over the time period, and a capacity portion associated with an upper threshold of electricity delivered to the power grid by the electric vehicle over the time period.

First claim

What is claimed is:

1. A vehicle-grid integration (VGI) management system comprising:
one or more computer storage media including data associated with a plurality of vehicles in a vehicle group including a first vehicle and computer-executable instructions; and
one or more processors configured to execute the computer-executable instructions to:
determine use of a power grid by the vehicle group, including use of the power grid by the first vehicle;
account for the use of the power grid by the first vehicle in a dual multi-part rate structure including:
a grid account portion representative of an underlying relationship between the first vehicle and the power grid,
a group account portion representative of an underlying relationship between the vehicle group and the first vehicle,
a consumption portion representative of a volume of electricity drawn from the power grid by the first vehicle over a predetermined time period,
a supply portion representative of a volume of electricity delivered to the power grid by the first vehicle over the predetermined time period,
a demand portion representative of an upper threshold of electricity drawn from the power grid by the first vehicle over the predetermined time period, and
a capacity portion representative of an upper threshold of electricity delivered to the power grid by the first vehicle over the predetermined time period;

analyze the use of the power grid by the vehicle group and one or more service parameters to select, from the plurality of vehicles in the vehicle group, the first vehicle;
use the one or more service parameters to generate one or more instructions for use in selectively operating the first vehicle; and
execute the one or more instructions to direct the first vehicle to at least one of draw electricity from the power grid and deliver electricity to the power grid.

2. The VGI management system of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions to select the first vehicle based on one or more of a vehicle status, a vehicle location, a vehicle territory, a state of charge, a fuel level, a fuel efficiency, a vehicle range, a traffic condition, a weather condition, a forecasted seasonal parameter, a vehicle fuel purchase price, a vehicle fuel sale price, a vehicle energy purchase price, and a vehicle energy sale price.

3. The VGI management system of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions to:
determine one or more vehicle group parameters associated with the vehicle group; and
use the one or more vehicle group parameters to determine the one or more service parameters.

4. The VGI management system of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions to:
determine one or more grid parameters associated with the power grid; and
use the one or more grid parameters to determine the one or more service parameters.

5. The VGI management system of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions to:
determine one or more station parameters associated with a charging station coupled to the power grid; and
use the one or more station parameters to determine the one or more service parameters.

6. The VGI management system of claim 5 , wherein the one or more processors are further configured to execute the computer-executable instructions to select the charging station based on one or more of a station status, a station location, an instrumentation, a fuel type, a station fuel purchase price, a station fuel sale price, a station energy purchase price, and a station energy sale price.

7. The VGI management system of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions to:
receive a service request; and
use the service request to determine the one or more service parameters.

8. A computing system for managing vehicle-grid integration, the computing system comprising:
a group module that determines an underlying relationship between an electric vehicle and a vehicle group;
a manager module that monitors use of a power grid by the vehicle group and accounts for the use of the power grid by the electric vehicle in a dual multi-part rate structure including a grid account portion, a group account portion, a consumption portion, a supply portion, a demand portion, and a capacity portion, wherein the manager module determines the use of the power grid by the electric vehicle using a first plurality of parameters associated with a drawing of electrical energy from a power grid by the electric vehicle and a second plurality of parameters associated with a delivery of electrical energy to the power grid by the electric vehicle, the first plurality of parameters including a first volume and a first threshold amount of electricity drawn from the power grid by the electric vehicle over a predetermined time period, the second plurality of parameters including a second volume and a second threshold amount of electricity delivered to the power grid by the electric vehicle over the predetermined time period, and wherein the grid account portion is representative of an underlying relationship between the electric vehicle and the power grid, the group account portion is representative of the underlying relationship between the electric vehicle and the vehicle group, the consumption portion is representative of the first volume, the supply portion is representative of the second volume, the demand portion is representative of the first threshold amount, and the capacity portion is representative of the second threshold amount; and
a control module configured to analyze one or more service parameters, the first plurality of parameters, and the second plurality of parameters to select, from a plurality of vehicles in the vehicle group, the electric vehicle, use the one or more service parameters to generate one or more instructions for use in selectively operating the electric vehicle, and execute the one or more instructions to direct the electric vehicle to at least one of draw electricity from the power grid and deliver electricity to the power grid.

9. The computing system of claim 8 , wherein the control module is configured to select the electric vehicle from the plurality of electric vehicles in the vehicle group based on one or more of a vehicle status, a vehicle location, a vehicle territory, a state of charge, a fuel level, a fuel efficiency, a vehicle range, a traffic condition, a weather condition, a forecasted seasonal parameter, a vehicle fuel purchase price, a vehicle fuel sale price, a vehicle energy purchase price, and a vehicle energy sale price.

10. The computing system of claim 8 , wherein the group module is configured to use the first plurality of parameters and the second plurality of parameters to determine one or more vehicle group parameters associated with the vehicle group, and the control module is configured to use the one or more vehicle group parameters to determine the one or more service parameters.

11. The computing system of claim 8 , further comprising:
