||The report deals with the design and data analysis of a heat engine-battery hybrid propulsion system for vehicles. The first portion of the work performed is devoted to the following tasks: evaluation of the performance of the Electromechanical Transmission (EMT) operating on a dynamometer; performance of engineering trade-off studies on the power conditioning units of the Speeder (generator) and Torquer (traction motor) subsystems and presentation of up-graded design criteria; assessment of the performance of the Speeder and Torquer machines and the presentation of design criteria for advanced versions of both machines; development of advanced operational concepts such as start-up techniques and means for up-grading the transfer of the Torquer system between the motor and generator operating states; development of analytic models of Torquer system operation and use of these models to assess the effect of design parameters. The second portion of the study was intended to provide operational data on the performance of an internal combustion engine when used within the context of a hybrid power train. (Author)
