Week-3 Challenge: ADVISOR Tool

RRameshkumar D21 Aug 2022

Aim:

To use the ADVISOR tool for simulation using MATLAB.

Objective:

Using EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, To find whether the vehicle can travel for 45 km with FTP drive cycle? and To Conclude observations.

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

To Perform gradeability test with PRIUS_Jpn_defaults_in file. To compare results in the table and conclude

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.

How To start ADVISOR Tool:

Launch MATLAB and first set default location folder to the advisor.
Now in the command window of MATLAB type “advisor” and press enter.
A new window will open and then set “metric” for unit and start ADVISOR.
It will launch in a new window.

Advisor tools have 3 windows:

1. Vehicle Input window

2. Simulation Parameter window

3. Results window

Question:1

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

Now changing the cargo mass to 500 kg
Change in the total mass of the vehicle can be seen.
Clicking on the continue button after that a new window simulation parameter will pop up.

Am we can set the drive cycle,

An after pressing the RUN button, the simulation will start and it will show results in a new window

Drive cycle 1,

we set the value for drive cycle, 2

An the result is her

No of drive cycles Distance in kms

1 17.8

2 35.5

The distance travel by car is 17.8 km with drive cycle CYC_FTP – 1 whereas the maximum distance travel by car is 41.4 which consumes 100% of battery in 3 Drive cycles.

Therefore EV_default cannot travel distance of 45 km due to insufficient .

Question 2:

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

An change“#of mod V nom” describes the battery capacity, so we will change the module number of batteries from the first box and we will see that changes in voltage and weight of the battery.
