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.
