Limited range, marginal performance and high cost are the major factors impeding potential market acceptance of electric vehicles. Advancing the technology of electric vehicle powertrains-motors, controllers and transmissions, will help reduce these objectionable electric vehicle characteristics. This paper discusses the NASA research contract, DEN 3-238, Advanced Electric Vehicle Powertrain Program, including technical characteristics of the powertrain concept being developed. The powertrain includes an ac induction motor, automatic transmission, final drive and differential integrated into a single unit mounted on the wheel axis, an electric subsystem (the ac motor, dc-ac inverter and inverter/motor controller), and a micro-computer-based vehicle control system. The electric subsystem, which includes an advanced power transistor, is being developed by General Electric, a major subcontractor for the program.
