Week-3 Challenge: ADVISOR Tool
AIM—
To use ADVISOR tool for simulation.
OBJECTIVE —
1. Use EV_defaults_in_file, if cargo mass is 500 kg with all other default conditions, find the vehicle can travel for 45 with FTP drive cycle? & conclude the observations.
2. By using above case, try changing battery capacity and repeat the simulation.
3. To perform gradeabiltity test with PRIUS Jpn_defaults_in_file to compare the results in the table and conclude.
INTRODUCTION —
ADVISOR tool developed in November 1994 by the national renewable energy laboratory(NREL). allows users to simulate and analyse conventional, advanced, light and heavy vehicles including hybrid electric and fuel cell vehicles. The tool allows users to access the effect of changes in vehicle components such as — motors, batteries. catalytic converters, climate control systems, and alternative fuels) and other modifications that might affect fuel economy, performance, or emissions.
It is a set of models, data, script text files for use with MATLAB & Simulink.
ADVANTAGES OF USING ADVISOR —
Estimate fuel economy of vehicles that have not been built yet.
Learn about how conventional, hybrid or electric vehicles use & lose energy throughout the drivetrains.
Compare relative tailpipe emissions produced on a number of cycles.
Valuate an energy management strategy for your hybrid vehicle fuel converter.
Optimize the gear ratios in your transmission to minimize fuel use or maximise performance, etc.
MAJOR COMPANIES WHICH USE ADVISOR TOOL ARE —
1. Daimler Chrysler.
2. Ford Motor Company.
3. General Motors Corp.
4. Delphi Automotive systems.
5. Visteon.
HOW TO START ADVISOR TOOL?
1. LAUNCH MATLAB and first set default location.
2. Now in command window of MATLAB type "ADVISOR" & press enter.
3. A new window will open and their set "matric" for unit and start "ADVISOR':
4. It will launch in a new window.
AVISOR tool have 3 windows-
1. Vehicle input window.
2. Simulation parameter window.
3. Result window.
1) Use EV_defaults_in_file, if cargo mass is 500 kg with all other default conditions, find the vehicle can travel for 45 with FTP drive cycle? & conclude the observations.
First we have to load EV_defualts_in file from drop down menu and change the parallel_default_in from vehicle input window.
Now changing the cargo mass to 500kg we will see change in total mass of the vehicle.
Now click on continue button after that a new window simulation parameter will pop up In simulation parameter window change the drive cycle to CYC_FTP by selecting the drop down menu.
Below that we will see # of cycles from here we can set our drive cycle.
After pressing the RUN button, the simulation will start and it will show results in new window.
The distance travelled by vehicle in 1 drive cycle is 17.8 KM.
Increasing the no. of drive cycles to 2
The distance travelled by vehicle in 2 drive cycle is 35.5 KM, with 80%of SOC used
Increasing the no. of drive cycles to 3
The distance travelled by vehicle in 2 drive cycle is 41.4 KM, with 100%of SOC used
| NO.OF CYCLES | DISTANCE COVERED IN KM |
| 1 | 17.8 |
| 2 | 35.5 |
| 3 | 41.4 |
The minimum distance travelled by the car is 17.8 KM with drive cycle CYC_FTP whereas maximum distance travelled by car is 41.4 which consumes 100% of the battery in 3 drive cycles.
Therefore, EV_default cannot travel distance of 45 KM in any drive cycle.
2.In above case, try changing the battery capacity and repeat the simulation.
• In this study the same default conditions are taken that are intiate in question land battery capacity will changed for accelerating the vehicle that will increase the vehicle distance travel km.
• ESS_PB 25 battery are used in this model we want to increase the battery power to obtain more vehicle travel distance.
• Here the max power is increased as 27 instead of default value 25 then select the continue option.
• Number of drive cycle is assigned as 3 by executing with same as working in the study 1.
• Now run the model, here cycle time is increased with 3 times for so that velocity of vehicle also increased during driven cycle. graphs shows the variation of velocity and battery capacity.
• It runs in certain distance while the power is provided from battery. while the power of battery is drained an vehicle remians stopped.
Results figure shows that vehicle travel distance as 32.2km
3.Perform gradeability test with PRIUSJpn_defaults_in file Compare your results in table and conclude.
STUDY-3:
Gradeability Test
If the gradeability checkbox is selected, a gradeability test will be run in addition to the chosen cycle. The grade displayed in the results figure will be the maximum grade maintainable at the input mph.
EXPLANATION OF STUDY:
To perform gradeability test with load file of PRIUSJpn_defaults_in that are initiate in question, there are two type of test observed in the gradeability.
• gradeability test by changing the speed.
• gradeability test by changing Grade and speed.
TEST-1: BY CHANGING THE SPEED,
Example-1
• In this test the default speed is given and the grade option is disabled to find the gradeability percentage of vehicle dring the speed of 55mph.
• Enable the gradeability test to obtain the percentage of gradeability driven in default speed. The test condition dialog box are shown below,
Hence greadebility at 88.5km/h is 8.9%
Example-2
• Here the default conditions are applied and speed is changed as 65mph duration of time(seconds) are in default condition same as the example 1 the gradeability test option is enabled to obtain the ouput as percentage of gradeability during the given input speed.
• Test condition dialog box are shown below to identify the input values and other default conditions.
Test Conditions 
Results figure shows that acceleration test. Hence gradeability at 65mph is 7.2% this will obtain by speed and the duration of test condition. Therefore the speed of vehicle will increase an gradeability of vehicle is decrease. 
OBSERVATION:
By the above examples the speed of the vehicle varies from above default speed the gradeability of vehicle is decrease. Therefore the speed of vehicle varies from below default speed gradeability of vehicle will increase.
TEST 2:
By changing Grade and Speed
Example-1
• In this test both speed and grade are changed in and grade option is enabled for differntitae the actual grade value. Gradeability test is selected and run the program.
• Speed is initiate as 25mph and grade are assigned as 15 percentage and duration of time are in default condition. Test condition dialog box are shown as below, 
Results figure shows the acceleration test that gradeability at 25mph is 15% this will obtain by speed and the grade value of test condition. Here the speed of vehicle is decrease the gradeability value is obtained as 15%. 
Example-2
• Speed is initiate as 70mph and grade are assigned as 10 percentage and duration of time are in default condition. Test condition dialog box are shown as below,
Results figure shows the acceleration test that gradeability at 70mph is not obtain in this speed of vehicle because the certain speed have the value of gradeability. High speed are not acted in slope region for certain gradeability conditions. 
OBSERVATION:
In this test the two examples shows that gradeability of vehicle is achived by some critical speed conditions. If speed of vehicle is decrease the gradeability will increase (e.g. the car sholud travel in hill with certain speed limit.)Hence the high speed is not possible in gradeability.
Example 2 shows that the gradeability is not achived at that vehicle speed.
