摘要

This study was conducted to verify that a four-passenger,quasi-electric drive (QED) vehicle of acceptable weight could obtain a range of 80km with improved lead acid batteries. The duel-fueled hybrid vehicle described is basically an electric vehicle (EV) augmented by a small heat-engine hybrid propulsion system for extended range capability. Usually the vehicle operates as an EV,since 75% of vehicle miles traveled in the United States consist of trips of 80km (50mi) or less. For longer trips,the driver may select the heat-engine hybrid mode or permit automatic switching to heat-engine power when the batteries reach a prescribed level of discharge. Three candidate propulsion systems having the greatest potential for early marketability were selected. Of the three systems analyzed,the flywheel/hydromechanical transmission configuration,requiring the smallest battery mass,is the lightest and most efficient. (ERA citation 04:034133)
