EPRI/TVA pilot electric vehicle demonstration: Update 1980

Although widespread use of EV´s has significant potential for favorable impacts on utility load curves, many questions regarding EV´s and EV subsystem characteristics remain unanswered. To focus on those aspects of EV´s of most importance to the energy supplier--the nation´s electric utilities--EPRI is participating with the Tennessee Valley Authority (TVA) in the research, development and demonstration of EV´s. Initiated in 1978, the EPRI-sponsored two-year pilot EV demonstration at TVA was designed to identify utility impact areas by demonstrating reliable electric vehicles in well-defined and controlled modes of use. Key data is being acquired on all aspects of EV performance, reliability, operations, network interaction, and subsystems. This paper discusses the EPRI/TVA EV demonstration program progress to date. Described are the planning and implementation phase, and the data acquisition system hardware.
