Hybrid Electric Vehicle Simulink Toolbox User's Guide, Technical Notes and PATHS Validation

Abstract : A general purpose toolbox was developed for modeling and simulation of electric and hybrid electric vehicles (HEV). This simulation and modeling toolbox, referred to as PATHS (Performance Assessment Toolbox for Hybrid Systems) was developed using Matlab(registered) and Simulink(registered). PATHS is a forward looking model organized into a suite of libraries, each containing modular computer models of typical HEV components. The objective of the developed toolbox is to provide the user the ability to model, simulate and analyze the performance of a custom built or pre-existing HEV. PATHS is a physics based modeling and simulation toolbox. The equations used to model the different components were derived from classical text books, using sound engineering methods. PATHS was also validated against a 22 foot series hybrid shuttle bus operated on a chassis dynamometer. This report is divided into the following sections: User's Guide, Technical Notes, and PATHS Validation.
