In this paper, modeling of battery designs for typical route vehicle missions and for random use in typical urban/suburban missions are presented from the standpoints of battery size, power characteristics, energy capacity, lifetime, and other performance requirements. The overall performance of the vehicle/battery combination is presented for the selected vehicle design. The sensitivities of battery characteristics and of battery component performances with regard to the mission requirements of electric vehicles are examined. A cost analysis for operating the vehicle and a safety and environmental study are discussed.
