NCSU Architecture: Black = Diesel Engine-Generator Unit, Red = FWD Electric Motor, Blue = Lithium-Ion Battery Pack

The NC State EcoCar team is designing a B20DEREV (B20 Biodiesel Extended Range Electric Vehicle), which is charachterized by a battery driven electric motor for propulsion and a diesle-engine generator for battery charging. To date, here are the specs of the vehicle design:

• A123 5×22S3P Lithium-Ion Battery Pack (22.3 kWh of total enery stored at full charge)
• 101X ETS Front-Wheel Drive electric motor from GM, Rated at 80 Kw (107 hp) continuous, 110 kW (148 hp) peak
• B20 Biodiesel Engine-Generator Unit (1.3L Diesel Engine, 20-40 kW Permanent Magnet Generator)

What do all these parts amount to? Preliminary computer modeling thus far tells us that our vehicle design will feature the following performance perameters:

• 65 miles of all-electric driving (leaving diesel tank empty & starting with 100% battery charge)
• 360 miles of range-extended driving (having diesel tank full & starting with 100% battery charge)
• 40 mpgge (miles per gallon gas equivalent) fuel economy
• 183 g/km Well-to-Wheel Greenhouse Gas Emissions
• 0.54 kWh/km Petroleum energy usage
• …and all while holding five passengers

Our final modeling results will be made available for public-view in our detailed technical report and abbreviated SAE format technical paper. Stay tuned and check back
