Accelerated adoption of electric drive vehicles could greatly diminish our dependence on foreign oil and reduce greenhouse gas emissions. President Obama has set a national goal of 1 million plug-in hybrid electric vehicles (PHEVs) in our national fleet by 2015. Large-scale deployment of these vehicles, each partially dependant on the electrical grid for power, will require careful integration between the transportation and electrical generation sectors. As the electrical grid expands it role to become a transportation fuel provider, it becomes important to view the vehicles and electric “fuel” infrastructure as a system. Technologies to improve the integration of electric vehicles and the grid, known as “V2G” technologies, could allow vehicle batteries to provide services to the grid, enhancing its reliability and stability, and enabling it to store excess renewable energy for times of peak demand. In this session, panelists will discuss the origins of the V2G model and will assess the policy, economic, and technical requirements for the establishment of a resilient, efficient national vehicle-to-grid system. Key topics will include designing new generations of PHEV powertrains, grid systems, and the controllers to integrate them and assessing the lifecycle energy use and environmental impacts of V2G configurations; the use of market signals to encourage consumer participation; and models to predict the impact of V2G technologies on national energy demand.
