ULTRA LIGHT ELECTRIC VEHICLES (EV)

Abstract
While this project reviewed the status of EV propulsion worldwide, and included European, American, and Japanese electric vehicles and the new Zebra sodium nickel chloride battery introduced by AEG of Daimler Benz at the September 1993 Frankfurt IAA motor show, and the November 1993 Tokyo motor show, this paper is limited in scope to showing results of a mathematical comparison which permits comparative assessment of 1993 EV automotive acceleration performance and the effects of vehicle configuration on the aerodynamic skin friction component of the total aerodynamic drag coefficient. Conclusions are: the major automobile manufacturers have been responsive, creative, and synergistic in developing and demonstrating significant improvements in acceleration performance and vehicle styling configuration strategies which may permit early deployment of ultralight electric vehicles with increased range. Consequently, the battery "Electric Vehicle" now has a brighter future.
