System-level mathematical model for evaluation of power train performance of load-leveled electric vehicles
This report documents the results of work completed in 1980. Until that time various design configurations of electric vehicles were being considered by industry, and numerous computer programs had been developed for predicting their performance. However, these programs were extensively detailed, expensive to run, based on different sets of assumptions and analytical approaches, and limited to specific systems. This made it very difficult to compare the performance capabilities and benefits of one design with another or gain insight into complex designs such as the Garrett electromechanically coupled flywheel system. It was also difficult to generate test plans and to formulate optimum strategies for a given set of conditions. The Electric and Hybrid Vehicles Project at the Jet Propulsion Laboratory identified the need for a simple parametric model that would evaluate and compare a number of different power trains on a common basis. The accuracy of this model for a specific system would depend upon the accuracies of individual component efficiencies and energy fractions that need to be obtained for selected driving conditions through tests or detailed models. However, the results predicted by this model would prove useful for system-level evaluation and comparison and for identifying potential advantages and limitations of one system over another.
