This paper discusses the recent National Academies' study Overcoming Barriers to Deployment of Plug-in Electric Vehicles. The study committee concluded that, if policy makers continue to pursue PEV deployment, continuing federal funding for battery research and purchase tax credits is important to reduce vehicle cost. The committee also considered federal investments in deploying charging infrastructure. It recommended further study to understand the relationship between infrastructure and

EVS29 International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium 2 This paper discusses the results of a recent National Academies' study that reviewed barriers to PEV adoption. The study committee that authored this report was composed of members with backgrounds in technology, policy, business, and consumer affairs related to electric vehicles. 1 The study, Overcoming Barriers to Deployment of Plug-in Electric Vehicles [1] , was requested by the U.S. Congress after hundreds of millions of dollars were spent on electric vehicle research and infrastructure deployment under the American Recovery and Reinvestment Act (ARRA) and the ongoing EV Project. ARRA included about $130 million to provide incentives for the purchase of thousands of PEVs, to install about 19,000 chargers, and to collect and analyze charging behaviors [2] . Congress, in its appropriations for fiscal year 2012 for the Department of Energy (DOE), rejected the Administration's request for $200 million for additional PEV deployment activities, including $150 million for charging infrastructure. Instead it directed the DOE, as part of its broader efforts on PEV deployment, to fund this study to identify the market barriers slowing the purchase and hindering the deployment of supporting infrastructure. The study covered an array of topics including vehicle and charging technologies; cost and performance of vehicle batteries; classes of PEVs and relationships between PEV classes and charging infrastructure needs; the consumer purchase and market development process; and possible roles for the federal government to reduce deployment barriers.
