HEV Modeling:
U.S. DOE/FreedomCAR Technical Team Support
Background
The U.S. Department of Energy (DOE) Office of Efficiency and Renewable Energy's FreedomCAR and Vehicle Technologies (FCVT) Program manages research and development efforts to help make cars and trucks more energy-efficient, while at the same time developing technologies that will help transition the United States to using vehicles that do not require petroleum fuels.
Considering the larger number of technologies considered in the FCVT Program and to be able to achieve the desired goals, a system approach is necessary to evaluate the impact of each component on the vehicle.
Argonne's Research
PSAT is an integral part of the FreedomCAR Vehicle Systems Analysis Technical Team (VSATT). VSATT's mission is to evaluate the performance and interactions of proposed candidate automotive powertrain components and subsystems, in a vehicle systems context, in order to provide direction for the various FreedomCAR and fuel technical teams' research in areas that maximize the potential for fuel efficiency improvements and emissions reduction.
Numerous activities have been completed to support the U.S DOE and FreedomCAR Technical Teams, including:
- Hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle component requirements
- Fuel economy sensitivity to vehicle mass
- Impact of drive cycle aggressiveness and speed on HEV fuel consumption sensitivity
- Comparison between hydrogen engine and fuel cell vehicle fuel economies
- Impact of FreedomCAR goals on well-to-wheel analysis
- Impact of combining hydrogen internal combustion engine with fuel cell system using PSAT
