Using ADVISOR for Analysis of HEVs Meisam Amiri amirim@ut.ac.ir Outline Needs for simulation tools Demonstration of ADVISOR Background on ADVISOR Capabilities of ADVISOR Working Principles of ADVISOR Using ADVISOR - Vehicle Templates - ADVISOR’s File System - Defining a vehicle - Running a simulation - Looking at outputs Engines & Emission Structure Using ADVISOR in an Optimization Loop Linking to ADVISORLi kit - ADAMS/ADVISOR Co-simulation Simulation of a Hybrid Electric vehicle Limitations Needs for simulation tools Many configurations / energy management / controlyggyg strategies Analytical solution is difficult Prototyping and testing is expensive & time consuming Optimization can be arduous task since there are literally h d d flit ll hundreds of parameters affecting itstff tiit performance Advisor Demonstration Background on ADVISOR ADVISOR = ADvanced VehIcle SimulatOR simulates conventional, electric, or hybrid vehicles (series, parallel, or fuel cell) ADVISOR was created in 1994 to support DOE Hybrid Program at NREL Released on vehicle systems analysis web site for free download in September, 1998 Downloaded by over 9000 people around world Background on ADVISOR Distributed on web by NREL from 1994-2002 In 2003, ADVISOR licensed to AVL for commercial release Users help provide component data and validation, feedback for future development Programmed in MATLAB/Simulink environment - graphical/object-oriented environment - allows flexibility in modeling new vehicles and control strategies ADVISOR Being Used Globally ADVISOR Downloads by Type of Organization Capabilities of ADVISOR Various vehicle types Conventional, S i h b id P ll l h b id and F l cellCtil Series hybrid, Parallel hybrid d Fuel ll Various control strategies Thermostat Power follower, Power assist etcfollowerThermostat,assist, etc. GUI or batch mode operation Parametric studies Performance assessments Trade-offTrade off studies Evaluating new technologies Capabilities of ADVISOR ADVISOR will allow the user to answer questions like: Was the vehicle able to follow the speed trace? How much fuel and/or electric energy were required in the attempt? How does the state-of-charge of the batteries fluctuate throughout a cycle? What were the peak powers delivered by the drivetrain components? What was the distribution of torques and speeds that the piston engine delivered? What was the average efficiency of the transmission? Predicts fuel economy, emissions, accel. performance and grade sustainability and optimization Working Principles ADVISOR operates in the MATLAB/Simulink environment Matlab is chosen for its programming ability modeling flexibilityability,flexibility, optimization toolbox and visualization tools Vehicle data is provided in Matlab files (m files) and modelsp() are developed in Simulink (calculations) pgppEmpirical model using drivetrain component performances Graphical User Interface (GUI), allows the user to model ayany type o ICE/EV/HEV by eas y c a g g t e vehi
