Electric vehicles give considerable energy and liquid fuel savings in urban use and their technical and economical acceptability depend on battery performance. The joint effort of five European Automobile Manufacturers was therefore addressed to identifying battery requirements and critical aspects and to characterizing accordingly batteries proposed by selected suppliers. The batteries tested ranged from flat plate batteries, with useful energy density of 27 Wh/Kg and deliverable power over 60 W, to heavy duty traction batteries with useful energy density of 24 Wh/Kg and deliverable power of approx. 30 W/Kg. The results obtained show that the batteries tested are adequate to power electric vehicles for specific market segments and that discharge/charge efficiencies of over 75 % can be achieved in daily recharges.
