Comparison of Modeled and Measured Energy Use in Hybrid Electric Vehicles

CarSim 2.5.4, written by AeroVironment, Inc. of Monrovia, California and SIMPLEV 3.0, written by Idaho National Engineering Laboratory were used to simulate two series-configured hybrid electric vehicles that competed in the 1994 Hybrid Electric Vehicle Challenge. Vehicle speed and battery energy use were measured over a 0.2-km maximum effort acceleration and a 58-km range event. The simulations'predictions are compared to each other and to measured data. A rough uncertainty analysis of the validation is presented. The programs agree with each other to within 5% and with the measured energy data within the uncertainty of the experiment.
