User`s guide to EAGLES Version 1.1: An electric- and gasoline-vehicle fuel-efficiency software package

PDF Version Also Available for Download.

Description

EAGLES is an interactive microcomputer software package for the analysis of fuel efficiency in electric-vehicle (EV) applications or the estimation of fuel economy for a gasoline vehicle. The principal objective of the EV analysis is to enable the prediction of EV performance on the basis of laboratory test data for batteries. The EV model included in the software package provides a second-by-second simulation of battery voltage and current for any specified vehicle velocity/time or power/time profile. The capability of the battery is modeled by an algorithm that relates the battery voltage to the withdrawn (or charged) current, taking into account ... continued below

Description

EAGLES is an interactive microcomputer software package for the analysis of fuel efficiency in electric-vehicle (EV) applications or the estimation of fuel economy for a gasoline vehicle. The principal objective of the EV analysis is to enable the prediction of EV performance on the basis of laboratory test data for batteries. The EV model included in the software package provides a second-by-second simulation of battery voltage and current for any specified vehicle velocity/time or power/time profile. The capability of the battery is modeled by an algorithm that relates the battery voltage to the withdrawn (or charged) current, taking into account the effect of battery depth-of-discharge. Alternatively, the software package can be used to determine the size of the battery needed to satisfy given vehicle mission requirements. For gasoline vehicles, a generic fuel-economy model based on data from EPA Test Car List 1991 is included in the software package. For both types of vehicles, effects of heating/cooling loads on vehicle performance, including range penalty for EVs, can be studied. Also available is an option to estimate the time needed by a specified vehicle to reach a certain speed with the application of a constant power and an option to compute the fraction of time and/or distance in a driving cycle at speeds exceeding a specified value. Certain parameters can be changed interactively prior to a run.
