AIM: To Use Of The Advisor Tool For Simulation.

Objectives:

Given Challenges In The Tasks

Introduction;

Advisor Tool, Developed In November 1994 By National Renewable Energy Laboratory (NREL), Allows User To Simulate And Analyze Conventional, Advanced, Light And Heavy Vehicles, Including Hybrid Electrical And Fuel Cell Vehicles. The Tool Allows User To Assess The Effect Of Changes In The Vehicle Components ( Such As Motor, Batteries, Catalytic Converter, Climate Control System) And Other Modifications That Might Affect Fuel Economy, Performance , Or Simulink .

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 Defaullt Location Folder To The Advisor.
Now In The Common Window Of The 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 Tool Have The Three Windows There Are The As Follows

Vehicle Input Window
Simulati0n Parmeter Window
Results Window

Q1: 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.

ANS:

First, Loading Ev_Default_ In From The Drop-Down Menu And Changing Parallel_ Default To Ev_Defaults _In From Vehicle Input Window

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.

In Simulation Parameter Wndow Changes Drive Cycle To CYC_FTP by selecting the drop _down menu.
Below That We Will See The # Of Cycles From Here We Can Set Out Drive Cycle.

After Pressing The Run Button, The Simulation Will Start And It Will Show The Results In A New Window.

The Distance Traveled By The Vehicle In 1 Drive Cycle Is 17.8km

Drive Cycle Count-2

After Pressing The Run Button, The Simulation Will Start And It Will Show The Results In A New Window.

The Distance Traveled By The Vehicle In 2 Drive Cycle Is 35.5 Km

Drive Cycle Count-3

After Pressing The Run Button, The Simulation Will Start And It Will Show The Results In A New Window.

THE DISTANCE TRAVELED BY THE VEHICLE IN 3 DRIVE CYCLE IS 41.4 Km

After 3 drive cycles, if we increase the drive cycle to 3,4,5,6 there is no changes in the distance traveled by the vehicle is same that is 41.4

So, observed in this task the distance travelled by the vehicle is lag than the 45 km

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

ans:

In- vehicle input window we will change the capacity of battery form energy storage which will be open in 1^st.
“# of mod V nom” describes the battery capacity, so we will change the module of batteries from the first box and we will see that changes and weight of the battery.
A new simulation parameter window will open, here we will change the drive cycle to 2 or 3, one at the time and run the simulation.
After completing of simulation, we will see the result window where we observe the change in distance of vehicle travel.
We can repeat this simulation by changing the battery module and the drive cycle.

Energy storage system with 26 modules and 2 drive cycle

# of modV has been changed to 26

After changing the values click on the continue button.
Here change the number of the drive cycle to 2

After changing the drive cycle to 2 click on run button.

The total distance travelled is = 35.5 km

Energy storage system with 26 modules and 3 drive cycles

After changing the drive cycle to 3 click on run button.

The total distance travelled is = 42.7 km

Energy storage system with 27 modules and 2 drive cycle

# of modV has been changed to 27

After changing the values click on the continue button.
Here change the number of the drive cycle to 2

After changing the drive cycle to 2 click on run button.

The total distance travelled is = 35.5 km

Energy storage system with 27 modules and 3 drive cycles

After changing the drive cycle to 3 click on run button.

The total distance travelled is = 44.8 km

Energy storage system with 28 modules and 2 drive cycle

# of modV has been changed to 28

After changing the values click on the continue button.
Here change the number of the drive cycle to 2

After changing the drive cycle to 2 click on run button.

The total distance travelled is = 35.5 km

Energy storage system with 28 modules and 3 drive cycles

After changing the drive cycle to 3 click on run button.

The total distance travelled is = 44.8 km

Observation:

With 2 drive cycles

Energy storage system distance travelled

26 35.5

27 35.5

28 35.5

With 3 drive cycles

Energy storage system distance travelled

26 42.7

27 44.8

28 46.3

Battery modules 28 and with 3 drive cycle, the distance traveled is 46.3 km.

Q:-3 Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Ans:

Select “Prius_JPN_default_in’ file from the load file option to load the Prius model

Hit continue and select the grade options to open the grade test options in this we need to change the option which will include both fuel and energy storage system, hence we will select all systems to enable and in basic parameters the speed of the vehicle can be controlled we need to change the speed from 5- 35 mph with the increment of 5mph to check the gradeability at different speeds.

After running the Prius model with different speeds, we can check the gradeability percentage, we need to take the values at different speeds and tabulate the information below.

With 5mph
