Battery Electric Passenger Vehicles - Comparative Assessment

During the interval from 1985 to 1993, the major automotive manufacturers of Western Europe, America, and Japan introduced experimental and prototype battery electric vehicles (EV) to the public. These electric vehicle technical developments have demonstrated that the automotive industry is responsive and creative in proposing potential solutions to the key concerns which have constrained the widespread application of the EV in the past. While this technical assessment included: identification of the key concerns and innovative solutions to aerodynamic drag reduction, tire loss reduction, and compared acceleration performance, vehicle range, regenerative braking, batteiy developments, fast recharging, unique passenger compartment heating and cooling solutions, and low mass vehicle structural materials; the scope of this paper is limited to reporting the performance and vehicle range results. The conclusions show that new technical developments have made the battery electric vehicle a more viable option. Consequently, transportation system policy makers now are considering the electric vehicle as an additional choice in devising intermodal transportation system strategies (1-9)¹
