Week-3 Challenge: ADVISOR Tool

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.

Answer:--

~What is "ADVISOR"

It was created by "National Laboratory for Renewable energy (NREL)" and "Department of Energy,USA", and it was the development phase was from 1994-2004 "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". and it uses backward flow model and ie, it acts from driving cycle to energy storage it is an steadty state and the ADVISOR TOOL MENU IN MATLAB is shown below.

ADVISOR TOOL MENU IN MATLAB:

STEPS FOLLOWED:

• To open ADVISOR first we have to open MATLAB and then in command window we have to type advisor.

• Once the ADVISOR tool menu is opened select The Metric/US which ever is required.

• Then the default Screen will be opened and the default values will be there and the default model will be Parallel Hybrid Vehicle and is shown below.

• SEARCH FOR 'EV_defaults_in' FILE FROM LOAD FILE AND CLICK THE FILE TO OPEN.

• IN ADVISOR TOOL THE SIMULATION CONSISTS OF EVERY PARAMETER OF VEHICLE MODELING, LIKE MASS, VEHICLE TYPE, ENERGY STORAGE, MOTOR, TRANSMISSION, WHEEL/AXLE, etc.
• NOW CHANGE SOME PARAMETERS WHICH PRESENT IN EV_defaults_in FILE, LIKE CARGO MASS TO 500 kg. AND IS SHOWN BY ARROW

• THEN CLICK CONTINUE TO OPEN THE SIMULATION PARAMETERS, THE SIMULATION PARAMETER CONSISTS OF DIFFERENT DRIVE CYCLE AND TO CREATE A INDIVIDUAL OWN DRIVE CYCLE BY GIVING DIFFERENT DATA TO THE SIMULINK PARAMETER LIKE, ACCELERATION TEST, GRADEABILITY TEST, PARAMETRIC STUDY, etc.

• NOW, SEARCH FOR 'CYC_FTD' FILE FROM DRIVE CYCLE LIST IN ADVISOR TOOL.

• AFTER CHANGING THE DRIVE CYCLE TO "CYC_FTP" PRESS RUN

• FOR NUMBER OF CYCLES IS EQUAL TO 1, AND VEHICLE TRAVELED THE DISTANCE IS 17.8 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 2, AND VEHICLE TRAVELED THE DISTANCE IS 35.5 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 3, AND VEHICLE TRAVELED THE DISTANCE IS 41.4 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 4, AND VEHICLE TRAVELED THE DISTANCE IS 41.4Km

• SIMILARLLY WE CHECKED FOR 10 CYCLES AND THE VEHICLE TRAVELED DISTANCE WAS 41.4 Km

FOR DEFAULT CONDITION:

NOW WE WILL CHECK THE DISTANCE TRAVELED WITHOUT CHANGING THE CARGO WEIGHT

• FOR NUMBER OF CYCLES IS EQUAL TO 1, AND VEHICLE TRAVELED THE DISTANCE IS 17.8 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 2, AND VEHICLE TRAVELED THE DISTANCE IS 35.5 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 3, AND VEHICLE TRAVELED THE DISTANCE IS 48.2 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 4, AND VEHICLE TRAVELED THE DISTANCE IS 48.2 Km

• SIMILARLLY WE CHECKED FOR 10 CYCLES AND THE VEHICLE TRAVELED DISTANCE WAS 48.2 Km

~can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.:--

ANSWER-1 RESULT, OBSERVATION

FROM THE ABOVE OBSERVATION WE CAN SEE

1. NO, THE VEHICLE CANNOT TRAVEL FOR 45 Km WITH FTP DRIVE CYCLE. BECAUSE IN INCREASES OF CARGO MASS TO 500 Kg, THE VEHICLE CAN ONLY TRAVEL UPTO 41.4 Km.
2. IF THE ORIGINAL DEFAULT CONDITION IS PRESENT WITH CARGO MASS AT 136 Kg, THE VEHICLE CAN TRAVEL UPTO 48.2 Km.
3. SO FROM THIS WE CAN GET TO KNOW THAT INCREASE IN WEIGHT LEADS TO LOSS IN POWER TO TRAVEL THE GREATER DISTANCE.

QUESTION NUMBER

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

STEPS FOLLOWED:

• To open ADVISOR first we have to open MATLAB and then in command window we have to type advisor.

• Once the ADVISOR tool menu is opened select The Metric/US which ever is required.

• Then the default Screen will be opened and the default values will be there and the default model will be Parallel Hybrid Vehicle and is shown below.

• SEARCH FOR 'EV_defaults_in' FILE FROM LOAD FILE AND CLICK THE FILE TO OPEN.

• IN ADVISOR TOOL THE SIMULATION CONSISTS OF EVERY PARAMETER OF VEHICLE MODELING, LIKE MASS, VEHICLE TYPE, ENERGY STORAGE, MOTOR, TRANSMISSION, WHEEL/AXLE, etc.
• NOW CHANGE SOME PARAMETERS WHICH PRESENT IN EV_defaults_in FILE, LIKE CARGO MASS TO 500 kg. AND IS SHOWN BY ARROW

• IF THE BATTERY CAPACITY IS BELOW 25 MODULES: WHICH IS 20 MODULES

• AND KEEPING THE DRIVE CYCLE TO FTP

• FOR NUMBER OF CYCLES IS EQUAL TO 1, AND VEHICLE TRAVELED THE DISTANCE IS 17.8 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 2, AND VEHICLE TRAVELED THE DISTANCE IS 33.5 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 3, AND VEHICLE TRAVELED THE DISTANCE IS 33.5 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 10, AND VEHICLE TRAVELED THE DISTANCE IS 33.5 Km

• IF THE BATTERY CAPACITY IS BELOW 25 MODULES: WHICH IS 35 MODULES

• AND KEEPING THE DRIVE CYCLE TO FTP

• FOR NUMBER OF CYCLES IS EQUAL TO 1, AND VEHICLE TRAVELED THE DISTANCE IS 17.8 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 2, AND VEHICLE TRAVELED THE DISTANCE IS 35.5 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 3, AND VEHICLE TRAVELED THE DISTANCE IS 53.2 Km

• FOR NUMBER OF CYCLES IS EQUAL TO 10, AND VEHICLE TRAVELED THE DISTANCE IS 56.5 Km

ANSWER-2 RESULT, OBSERVATION:

1. WHENEVER THE BATTERY CAPACITY IS LESS THEN 25 MODULES, THE VEHICLE GETS LESS DISTANCE TRAVELED
2. WHENEVER THE BATTERY CAPACITY IS MORE THEN 35 MODULES, THE VEHICLE GETS MORE DISTANCE TRAVELED
3. BECAUSE THE BATTERY CAPACITY WHICH IS POWER OR ENERGY STORAGE THAT THE VEHICLE IS DEPEND ON TO TRAVEL THE CERTAIN DISTANCE.
4. IF ENERGY IS MORE THE DISTANCE TRAVELED BY VEHICLE IS MORE, AND IF THE ENERGY IS LESS THE DISTANCE TRAVELED BY VEHICLE IS LESS.

QUESTION NUMBER

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

ANSWER:--

STEPS FOLLOWED:

• OPEN THE ADVISOR TOOL AND CLICK START TO OPEN THE VEHICLE INPUT IN ADVISOR SIMULATOR.
• SEARCH FOR 'PRIUS_JPN_defaults_in' FILE FROM LOAD FILE AND CLICK THE FILE TO OPEN.

• THEN CLICK CONTINUE TO OPEN THE SIMULATION PARAMETERS, THE SIMULATION PARAMETER CONSISTS OF DIFFERENT DRIVE CYCLE AND TO CREATE A INDIVIDUAL OWN DRIVE CYCLE BY GIVING DIFFERENT DATA TO THE SIMULINK PARAMETER LIKE, ACCELERATION TEST, GRADEABILITY TEST, PARAMETRIC STUDY, etc.

• NOW, SEARCH FOR ANY FILE FROM DRIVE CYCLE LIST IN ADVISOR TOOL.AND TICK TO THE GRADABILITY TEST OPTION

• OPEN THE GRADE OPTIONS MENU FOLDER,NOW PERFORM THE GRADEBILITY TEST

• NOW CONSIDER "ALL SYSTEM ENABLED" FROM "ENERGY STORAGE DISABLED AND KEEP SPEED VALUE AT 70 mph.

• SO BY VARYING THE VALUE OF SPEED IN GRADE OPTION MENU WE GET THE GRADEABILITY PERCENTAGE.

• SO BY KEEPING THE ALL SYSTEM ENABLE, SPEED VS GRADEABILITY(%) IS TAKEN FROM THE ADVISOR TOOL IN TABLE RESULT

ANSWER-3 RESULT, OBSERVATION:

IF the speed increases the Gradability percentage decreses and is shown in the above table
