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.
• 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.
• 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.

1. OPEN THE ADVISOR TOOL AND CLICK START TO OPEN THE VEHICLE INPUT IN ADVISOR SIMULATOR.
2. SEARCH FOR 'EV_defaults_in' FILE FROM LOAD FILE AND CLICK THE FILE TO OPEN.
3. IN ADVISOR TOOL THE SIMULATION CONSISTS OF EVERY PARAMETER OF VEHICLE MODELING, LIKE MASS, VEHICLE TYPE, ENERGY STORAGE, MOTOR, TRANSMISSION, WHEEL/AXLE, etc.
4. NOW CHANGE SOME PARAMETERS WHICH PRESENT IN EV_defaults_in FILE, LIKE CARGO MASS TO 500 kg.

in parameter select CYC FTP and used no of cy cycle 20 times

if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle

• FOR NUMBER OF CYCLES IS EQUAL TO 20, AND VEHICLE TRAVELED THE DISTANCE IS 41.4 Km which is 25.7 miles

FOR DEFAULT CONDITION

fOR NUMBER OF CYCLES IS EQUAL TO 20 , AND VEHICLE TRAVELED THE DISTANCE IS 48.2 Km which is 30 miles as we can see below.

conclusion

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 INCREASE IN WEIGHT LEADS TO LOSS IN POWER TO TRAVEL THE GREATER DISTANCE.

Solution 2

so as privious data i increase the battery capacity form 25mod to 30 mod with cargo weight of 500 and rus the cycle 20 times result shown below

FOR NUMBER OF CYCLES IS EQUAL TO 4, AND VEHICLE TRAVELED THE DISTANCE IS 49.1 Km which is 30.5 miles

if the battrey capacity is less than 25 mod than

FOR NUMBER OF CYCLES IS EQUAL TO 20, AND VEHICLE TRAVELED THE DISTANCE IS 33.5 Km which is 20.8

1. WHENEVER THE BATTERY CAPACITY IS LESS THEN 25 MODULES, THE VEHICLE GETS LESS DISTANCE TRAVELED
2. WHENEVER THE BATTERY CAPACITY IS MORE THEN 30 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.
5. HERE THE 25 MODULES ARE TAKEN AS DEFAULT DATA VALUE IN BATTERY CAPACITY.

Solution 3

gradeability test

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

1. 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 PERFORM THE GRADEBILITY TEST:

1. OPEN THE GRADE OPTIONS MENU FOLDER

1. NOW CONSIDER "ALL SYSTEM ENABLED" FROM "ENERGY STORAGE DISABLED AND KEEP SPEED VALUE AT 55 mph.
2. 
3. SO BY VARYING THE VALUE OF SPEED IN GRADE OPTION MENU WE GET THE GRADEABILITY PERCENTAGE.
4. gradeability at 55mph is 8.9%
5. BY VARYING THE SPEED VALUE WHICH is GIVEN BELOW FROM SIMULINK RESULT FOR GRADEABILITY WE GOT THE VALUES THAT PRESENT BELOW.
6. gradeability at 1mph is 31.7%
7. gradeability at 10mph is 30.3%
8. gradeability at 40mph is 11.7%

conclusion:

1. IF SPEED IS LESS, THE GRADEABILITY PERCENTAGE IS MORE
2. IF SPEED IS MORE, THE GRADEABILITY PERCENTAGE IS LESS
3. SO SPEED AND GRADEABILITY PERCENTAGE ARE INVERSELY PROPORTIONAL TO EACH OTHER
