The University of Wisconsin - Madison Hybrid Vehicle Team has designed, fabricated, tested and optimized a four-wheel drive, charge sustaining, split-parallel hybrid-electric crossover vehicle for entry into the 2006 Challenge X competition. This multi-year project is based on a 2005 Chevrolet Equinox platform. Trade-offs in fuel economy, greenhouse gas impact (GHGI), acceleration, component packaging and consumer acceptability were weighed to establish Wisconsin's Vehicle Technical Specifications (VTS). Wisconsin's Equinox, nicknamed the Moovada, utilizes a General Motors (GM) 110 kW 1.9 L CIDI engine coupled to GM's 6-speed F40 transmission. The rear axle is powered by a 65 kW Ballard induction motor/gearbox powered from a 44-module (317 volts nominal) Johnson Controls Inc., nickel-metal hydride hybrid battery pack. It includes a newly developed proprietary battery management algorithm which broadcasts the battery's state of charge onto the CAN network. The vehicle is fueled by a 20% blend of biodiesel (B20), which has a lower GHGI impact than conventional diesel fuel. With 175 kW of total power, the vehicle has a curb mass of 1982 kg and out-powers the stock Equinox by 0.4 seconds in the 0-96.6 kph (0-60mph) acceleration run. The Moovada surpasses Tier 2 Bin 5 emissions certification and achieves an estimated 15.5 km/L (36.5 mpg) combined fuel economy.
