The research on electrically-fueled highway vehicles that can be used as general-purpose vehicles identifies and evaluates energy-storage devices for use in automobiles and determines which energy-storage power systems are credible alternatives to the present internal-combustion-engine system. Performance of the task is outlined. The energy-storage propulsion systems can be divided into three categories: electricity utilization, alternative fuel utilization, and petroleum fuel-economy improvement. Results are specifically discussed for electricity utilization. It is concluded that automotive electrical power systems can be developed for various performance levels; most energy-storage vehicles or electricity-using vehicles will weight more and cost more than their internal-combustion-engine quivalents; if performance of these vehicles is reduced, then they can be more cost-competitive with today's internatl-combustion-engine vehicles; all advanced energy-storage devices and vehicles are high-risk developments; no future battery system of those remaining can be projected as a clear choice for development, given the present state-of-the-art and the uncertainties of future battery characteristics; and pure mechanical-energy-storage propulsion systems will not have sufficient specific energy for most vehicle applications. These devices, specially flywheels, do appear useful as power boosters for both electric and hybrid vehicles in certain mission applications. (ERA citation 05:005946)
