ADVISOR TOOL FOR SIMULINK:

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.

ADVISOR TOOL MENU IN MATLAB:

QUESTION-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-1:

STEPS FOLLOWED:
OPEN THE ADVISOR TOOL AND CLICK START TO OPEN THE VEHICLE INPUT IN ADVISOR SIMULATOR. 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.
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.
THE CLICK THE FILE WHICH IS 'CYC_FTP' DRIVE CYCLE.
NOW CLICK THE RUN TO GET THE RESULT.
FOR DEFAULT CONDITION:

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 10, AND VEHICLE TRAVELED THE DISTANCE IS 48.2 Km

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 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 10, AND VEHICLE TRAVELED THE DISTANCE IS 41.4 Km

RESULT:

No, The vehicle cannot travel for 45Km with FTP Drive cycle. Because increase in cargo mass to 500Kg, will leads vehicle to travel upto 41.2Km.
As from the specification of this vehicle its default cargo mass is 136Kg, which can travel upto 48.2Km.
So increase in weight will loss in power to travel the greater distances.

QUESTION-2: For the EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, try changing the battery

capacity and repeat the simulation.

ANSWER-2

STEPS FOLLOWED:

OPEN THE ADVISOR TOOL AND CLICK START TO OPEN THE VEHICLE INPUT IN ADVISOR SIMULATOR.
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 CHANGE IN BATTERY CAPACITY.
IF THE BATTERY CAPACITY IS BELOW 25 MODULES: WHICH IS 20 MODULES.

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 4, AND VEHICLE TRAVELED THE DISTANCE IS 33.5 Km

IF THE BATTERY CAPACITY IS ABOVE 25 MODULES: WHICH IS 30 MODULES

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

RESULT:

Whenever the battery is less than 25 modules, the vehicle can cover short distance.
Whenever the battery is more than 30 modules, the vehicle can travel up to more distance.Because vehicle is totally depends upon the power delivered by the battery.
Here the 25 modules are taken as default data value in battery capacity.

QUESTION-3: Perform gradeability test with PRIUS_Jpn_defaults_in file.

ANSWER-3:

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
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.
THE CLICK THE FILE WHICH IS 'CYC_FTP' DRIVE CYCLE.
NOW PERFORM THE GRADEBILITY TEST:
1. OPEN THE GRADE OPTIONS MENU FOLDER
3. NOW CONSIDER "ALL SYSTEM ENABLED" FROM "ENERGY STORAGE DISABLED AND KEEP SPEED VALUE AT 55 mph.
5. SO BY VARYING THE VALUE OF SPEED IN GRADE OPTION MENU WE GET THE GRADEABILITY PERCENTAGE.
7. BY VARYING THE SPEED VALUE WHICH is GIVEN BELOW FROM SIMULINK RESULT FOR GRADEABILITY WE GOT THE VALUES THAT PRESENT BELOW.
11. SO BY KEEPING THE ALL SYSTEM ENABLE, SPEED VS GRADEABILITY(%) IS TAKEN FROM THE ADVISOR TOOL IN TABLE RESULT
