An analysis of the energy efficiency, range, and attributable emissions of electric vehicles, and an assessment of the United States Department of Energy Electric and Hybrid Vehicle Program from 1976-2000

Over the last decade, much attention has focused on the efforts of the federal government and private industry working together through public-private partnerships to develop electric and hybrid vehicle technologies. These efforts have taken place principally through the United States Advanced Battery Consortium (USABC) and the Partnership for a New Generation of Vehicles (PNGV). Generally not appreciated is the extent of federal government investment in electric and hybrid vehicle research and development (R&D) that predates the USABC and PNGV ventures. The U.S. Department of Energy's Electric and Hybrid Vehicle Program (EHV Program) was established through an act of Congress in 1976 and has operated continuously since that time. The EHV Program has made significant contributions to the development of advanced battery technology. The program has funded research in fourteen distinct battery chemistries, has helped to establish a technology infrastructure in the field of battery development.; This thesis has two guiding questions. First, what is it that makes developing adequate batteries for electric and hybrid vehicles so challenging? Second, what can and should the federal government do to hasten development of battery technologies for these advanced vehicles? In response to the first question, an analysis of the energy requirements of electric vehicles is presented, estimating vehicle range, efficiency, and emissions benefits based on available technology. Emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) are considered, and compared to conventional heat engine vehicles to estimate the potential reductions in transportation sector emissions.; To address the second question, a review of technology policy since the Ford administration is presented. This discussion provides a background necessary to interpret the waxing and waning fortunes of the EHV Program over more than a quarter century. Reviews of government documents and interviews with battery development experts and government officials are used to provide insight into the goals and funding priorities of the EHV Program, and to evaluate the program's effectiveness.
