Validation of ADVISOR as a Simulation Tool for a Series Hybrid Electric Vehicle 981133

One of the most widely used computer simulation tools for hybrid electric vehicles (HEVs) is the ADvanced VehIcle SimulatOR (ADVISOR) developed by the National Renewable Energy Laboratory. The capability to quickly perform parametric and sensitivity studies for specific vehicles is a unique and invaluable feature of ADVISOR. However, no simulation tool is complete without being validated against measured vehicle data to insure the reliability of its predictions. This paper details the validation of ADVISOR using data from the Virginia Tech FutureCar Challenge Lumina, a series HEV. The modeling process is discussed in detail for each of the major components of the hybrid system: transmission; electric motor and inverter; auxiliary power unit (fuel and emissions); batteries; and miscellaneous vehicle parameters. The integration of these components into the overall ADVISOR model is also described.
The results of the ADVISOR simulations are then explained. These results are compared to measured vehicle data on energy use, fuel efficiency, emissions output, and control strategy function for a variety of driving cycles and test procedures. Uncertainties in the measured data are discussed. Finally, the discrepancies between predicted and actual behavior are analyzed. This validation process shows that ADVISOR has extensive value as a simulation tool for HEVs. The existing limitations of the program are also discussed, with recommendations for improvement.
