INTRODUCTION

What is 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.Effective advising programs use tools and technologies to help advisors communicate with students, campus partners, and other stakeholders; to manage student information; and to share information and resources. 

            Technology permeates our students’ lives, and plays an essential role in their educational experiences. Consequently, advising units need to integrate appropriate communication and information tools in all aspects of the advising process, from outreach, recruitment, and retention, to management, delivery, and evaluation of the unit’s services and programs. To achieve this, units should regularly evaluate their technological capacities and evaluate their students’ technological preferences.

 The Benifit of using ADVISOR TOOL 

• Estimate the fuel economic of vehicles that have not yet been built.
• Learn about how conventional, hybrid or electric vehicle use (and lose) engery throuhout their drivetrains. Comare 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 "

1.Launch MATLAB and first set default loction folder to the advisor.

2.Now in the command window of MATLAB type '' advisor '' and press enter.

3.A new window will open and then set '' metric " for unit and strat ADVISOR.

4.It will latunch in new window.

Advisor tools have three window

1. Vehicle Input Window.

2. Simulation Parameter Window.

3. Result Window.

 

 

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.

First, loading EV_default in from the drop- down menu and changing parallel_defult _in to EV_Defults_in from vehicle input windows.

• 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 windows simulation parameter will pop up.

 

VEHICLE INPUT 

• In Simulation Parameter Window change drive cycle to CYC_FTP by selecting the drop -cycle menu.
• Below that we will see # cycles from here we can set our drive cycle.

 

Increasing no. of drive cycles to 1.

• After pressing the RUN button, the simulation will start and it will show results in a new window.

 

RESULT

The distance traveled by the vehicle in 1 drive cycle is 17.8km.use almost 40 % SOC.

 

Increasing no. of drive cycles to 2.

Result with 2 Drive cycles.

The Distance Traveled by the vehicle in 2 Drive cycles is 35.5km. Used almost 81% SOC

 

Increasing No. of Drive cycles to 3.

 

Result With 3 Drive Cycles.

The Distance Traveled by the vehicle in 3 Drive cycles is 48.2km Used completely 100% SOC.

No. of Drive Cycles	Distance Covered in kms
1	17.8
2	35.5
3	48.2

 

     The Minimum Distance travel by car 17.8km with drive cycle CYC_FTP-1 Where as the maximum distance travel by car 48.2km which consumes 100% of Battery in 3 Drvie Cycle.

Terefore EV_Default travel Distance of 45km above (48.2km) 

 

 

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

•  In-Vehicle Input window we will change the capacity of Battery from energy storagewhich will be open in 1"st.
• '' # of mod V nom'' describes the battery capacity, so we will change the module number of battery from the first box and we will see that changes in voltage and weight of the batter.

• 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.

 

1) Energy storage sytem with 25 modules and 2 Drive cycles.

Result.

 

2) Energy storage sytem with 26 modules and 2 Drive cycles.

Result.

 

3) Energy storage sytem with 27 modules and 2 Drive cycles.

Result.

 

4) Energy storage sytem with 25 modules and 3 Drive cycles.

Result.

 

5) Energy storage sytem with 26 modules and 3 Drive cycles.

Result.

 

 

6) Energy storage sytem with 27 modules and 3 Drive cycles.

Result.

 

 

Drive Cycle -2

Battery Mod	Voltage	km	Battery Weight
25	308	35.5	275
26	321	35.5	286
27	333	35.5	297

 

Drvie Cycle -3

Battery Mod	Voltage	km	Battery Weight
25	308	48.2	275
26	321	49.7	286
27	333	51.8	297

 

• Battery modules 27 and with 3 drive cycles, the distance traveled is 51.8km
• While changing the battery module in drive cycle 2 we get constant distance trevel.
• Changing the battery module in drive cycle 3 we get changes in distance trvel by vehicle.
• we can see that, by increasing the battery capacity ,the vehicle can travel for more than 51.8kms .and Similary, where we decrease the battery capacity , the vehicle travel a lesser Distance.

 

 

3.   Perform gradeability test with PRIUS_Jpn_defaults_in file 

Compare your results in table and conclude. 

•  In ADVISOR Tool input window select PRIU_JPN_defaults model.

• continue to the next window.
• simulation parameter window will open.
• selected the Gradeability Test and click on the grade option box,a new dialogue box will open.

• In grade option box we can change speed or duration with respect to our simulation.
• So, for this simulation, I change speed one time and duration anothertime.
• Click on All system enabeled.
• Also, click on constant road grade.
• Click on and run the simulation and a Result window will open showing different result depend upon input data.

From the above tables, it can be seen that when vehicle speed increases there is a decrease in gradeability for both 10 sec and 20 sec Duration.

 # When vehicle speed increases there is a Decrease in Gradeability #
