The objective of this study was to evaluate a number of hybrid propulsion systems for application in several different vehicle sizes. A conceptual design was prepared for the most promising configuration. The program was divided into several tasks during which the various system configurations were parametrically evaluated and compared, design tradeoffs performed, and a conceptual design produced. Fifteen vehicle/propulsion system concepts were parametrically evaluated to select two systems and one vehicle for detailed design tradeoff studies. A single hybrid propulsion system concept and vehicle (five-passenger family sedan) were selected for optimization based on the results of the tradeoff studies. The final propulsion system consists of a 65-kW spark-ignition heat engine, a mechanical continuously variable traction transmission, a 20-kW permanent magnet axial-gap traction motor, a variable frequency inverter, a 386-kg lead-acid improved state-of-the-art battery, and a transaxle. The system was configured with a parallel power path between the heat engine and battery. It has two automatic operational modes: electric mode and heat engine mode. Power is always shared between the heat engine and battery during acceleration periods. In both modes, regenerative braking energy is absorbed by the battery. In the electric mode the battery (80% depth of discharge) provides an electric range of 218 km, when it is using petroleum at the rate of 30 km/liter. In the heat engine mode the mileage is 14 km/liter. The propulsion system has a life-cycle cost of $0.054/km. The vehicle has a test weight of 2032 kg and can accelerate from 0 to 90 km/hr in 12 s. It has a top speed of 105 km/hr and a steady-state hill climbing capability of 90 km/hr on a four percent grade. (ERA citation 05:027424)
