V2G or Vehicle-to-Grid allow the electricity to flow from electric car to power lines

Electric vehicles, whether powered by lithium ion batteries, fuel cells, or gasoline hybrids, have within them the energy source and power electronics capable of producing the 60 Hz AC electricity that powers our homes and offices. When connections are added to allow this electricity to flow from electric cars to power lines, we call it "vehicle to grid" power, or V2G.

Cars pack a lot of power. One typical electric-drive vehicle can put out over 10kW, the average draw of 10 houses. The key to realizing economic value from V2G is precise timing of its grid power production to fit within driving requirments while meeting the time-critical power "dispatch" of the electric distribution system.

The 3rd Edition of Vehicle-to-Grid Power: Challenges and Opportunities is a 40-page report which seeks to pull together information on the current status of V2G power into a comprehensive overview to provide a high level understanding of the business opportunities and challenges of V2G.

High gas prices, carbon constraints, fuel economy standards, and the desire for energy independence are pushing the development of electric vehicles. Rather than being a burden to the electric industry, millions of electric cars could be a blessing by providing important ancillary services, peaking power, and even energy storage for wind power plants.

In order to be prepared to take advantage of V2G, this report seeks to provide readers with an understanding of the potential amount of capacity and energy V2G can provide to the grid, the options the industry can use to harness these capabilities, and the decisions that need to be made now to encourage V2G development and ensure its potential is maximized.

Vehicle-to-Grid Power: Challenges and Opportunities provides industry participants with an understanding of V2G and its potential for positively impacting electricity markets.

Topics covered in the report include:

– Explanation of how EDVs can be used to provide power to or receive power from the grid
– Analysis of the basic infrastructure requirements necessary for V2G to be implemented
– Evaluation of the different functions that V2G can provide
– Discussion of the factors that limit the capacity and energy delivered by V2G
– Analysis of the business opportunities available for V2G
– Identification of the services that V2G can provide and the different business models that can be used
– Analysis of the economics of V2G
– Discussion of how V2G can help expand the amount of wind power on the grid
– Evaluation of the challenges which may hinder the commercialization of V2G
– Profiles of key V2G trials and demonstration projects
