Energy utilization in an electric vehicle is one of the most important factors in determining the customer acceptance of the vehicle. The relatively low energy and power densities of the available batteries coupled with the requirement of achieving acceptable range make it imperative that the overall system efficiency be maintained at a high level without sacrificing acceleration performance and other driveability characteristics of the vehicle. Given the opportunity to simultaneously specify all of the major powertrain components, it is possible to use a systematic approach to achieve the best utilization of the available battery energy. This paper describes one such approach that was used in the development of the design specifications for the components of an advanced AC powertain which is being developed and built under contract DE-ACOB-82NV-10308, supported by the Department of Energy's electric and hybrid vehicle program. Described in detail are the analysis and the tradeoff studies that were undertaken as well as results from an extensive simulation of the powertrain.
