Week-3 Challenge: ADVISOR Tool

ADVISOR, NREL’s ADvanced VehIcle SimulatOR, is a set of model, data, and script text files for use with Matlab and Simulink. It is designed for rapid analysis of the performance and fuel economy of conventional, electric, and hybrid vehicles. ADVISOR also provides a backbone for the detailed simulation and analysis of user defined drivetrain components, a starting point of verified vehicle data and algorithms from which to take full advantage of the modeling flexibility of Simulink and analytic power of MATLAB.

You may benefit from using ADVISOR if you want to:

• estimate the fuel economy of vehicles that have not yet been built
• learn about how conventional, hybrid, or electric vehicles use (and lose) energy throughout their drivetrains
• compare relative tailpipe emissions produced on a number of cycles
• evaluate an energy management strategy for your hybrid vehicle’s fuel converter
• optimize the gear ratios in your transmission to minimize fuel use or maximize performance, etc.

The models in ADVISOR are:

• mostly empirical, relying on drivetrain component input/output relationships measured in the laboratory, and
• quasi-static, using data collected in steady state (for example, constant torque and speed) tests and correcting them for transient effects such as the rotational inertia of drivetrain components.

ADVISOR was preliminarily written and used in November 1994. Since then, it has been modified as necessary to help manage the US DOE Hybrid Vehicle Propulsion System subcontracts. Only in January 1998 was a concerted development effort undertaken to clean up and document ADVISOR.

Since then, over 4500 individuals have downloaded one or more versions of ADVISOR, including all of the OEMs and major suppliers. About 2/3 of the users are from industry and 1/3 from universities. A short list of major ADVISOR users includes:

• DaimlerChrysler
• Ford Motor Company
• General Motors Corp.
• Delphi Automotive Systems
• Visteon
• and hundreds of others

1. For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.

when we take Cargo mass is 500kg.

- FTP Drive cycle

In FTP one drive cycle it covered distance of 17.7km

FOR range of 45 km the vechile must run for 3 drive cycle

conclusion - it failed to run 45 km after 3 FTP drive cycle it covered 41.4km

2. In the above case, try changing the battery capacity and repeat the simulation.

case1

battery capacity is 25

case 2

when battery capacity increase too 35

here, we can see that when the battery capacity increase the range of vechile is also increase (to 53.3km)

and when we decresae the battery capacity its range also decrease..

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Speed - 70km

Hybrid

fully electric

IC Engine -

FOR Speed 50

hybrid

Fully electric-

IC Engine-

we conclude that when we increase the speed then the gradeability will decrease
