A Comparison of Modeled and Measured Energy Use in Hybrid Electric Vehicles

Abstract

<div class="htmlview paragraph">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.</div>
