UW Hybrid Vehicle Team

The EcoCar Challenge is a three-year competition sponsored by the U.S. DOE, GM, and Argonne National Labs for 2008-2010. Seventeen universities from the US and Canada were selected to participate. In the first year, teams concentrated on designing, modeling, and simulating their teams proposed vehicle architecture. Additionally, teams worked to create a functional HIL (hardware-in-the-loop) to demonstrate their capability to manage a vehicle's ECU. The first year's competition was completed in June 2009 in Toronto, OH Canada.

In the first year of the competition, the UWHVT developed an architecture that was a powersplit hybrid design. Technical papers were created at intervals throughout the year dictating decisions and results of simulations. It consists of a prototype traction motor, the 150 kW Continental AG Sapphire drive. A Weber MPE 750 engine (operating on E85) and the Delphi DU174 motor (found in the EV1) complete the genset. A clutch implemented in between the DU174 and the Weber allow for efficient all electric drive, while a clutch implemented in between the DU174 and the rear differential allows the Weber engine to be directly coupled to the road at highway speeds. Lastly, the battery pack located in the spare rear wheel compartment will be a Johnson Controls Saft 41Ah lithium-ion pack.

The UWHVT expects to receive its stock Saturn Vue in August 2009 and proceed building the vehicle in year 2. Competition for year two of the challenge will be in Yuma, AZ at GM's new proving ground.^[1]
