Week-3 Challenge: ADVISOR Tool

AIM: To Use ADVISOR tool and simulate the

1. 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.
2. Try changing the battery capacity.
3. Perform Gradeability test with PRIUS Jpn defaults in file.

ADVISOR:

ADVANCE VEHICLE SIMULATOR tool was created by the NREL (NATIONAL RENEWABLE ENERGY LABORATORY) in the Department of energy, USA. It was Development phase from 1994 to 2004. MATLAB/Simulink based simulation program for Rapid Analysis of the performance and fuel efficiency of conventional electric and hybrid vehicle and also used to test for backward flow from driving cycle to energy storage. Vehicle Models are most experiential relaying on drive-train component of input and output relationship measured in the laboratory.

ADVISOR is a Graphical User Interface (GUI) system. This tool allows users to assess the effect of changes in vehicle components such as motors, batteries, catalytic converters, climate control systems, and alternative fuels and other modifications that might affect fuel economy, performance, or emissions.

STEPS TO OPEN ADVISOR TOOL IN MATLAB

Step 1: Download the ADVISOR tool.

Step 2: Open MATLAB.

Step 3: Change the MATLAB path in the Directory path and by selecting the folder path and right click on it and select add from path --- select folders and subfolders.

Step 4: Open Command window in MATLAB and type ADVISOR and press enter.

Step 5: ADVISOR window will open and select the Metric units and click on start.

ADVISOR Tool Window in MATLAB

ADVISOR tool will open and search for the EV_defaults_in in the Load file.

Change the vehicle input like Cargo mass to 500kg as per given considerations and click on continue to go for next page of the tool.

Simulation Parameter window will open then selects the Driving cycle of CYC_FTP as per the given considerations and we can see the vehicle parameters like time, distance, maximum speed of the vehicle, maximum acceleration etc., We can also change the no of driving cycles as per our requirements. We can enable the Acceleration and Gradeability test to the vehicle.

Parametric study refers to the effect of change in a typical value there are 3 variable with the 3 conditions. Optimize cs vars refers to the optimization of control strategy of the variables.

Go for RUN

The results of ADVISOR window will appear and we can change the vehicle components, plot variables, we can select the maximum 4 plots. It shows Fuel consumption per 100kms is 0. I have Disable the Acceleration test and Gradeability test. The above results shows the energy storage system state of charge (SOC) gradually decreases from the 100% to 60%. As the speed increases the soc slightly reduces and when the vehicle is at rest position the soc comes down to 60%.

OUTPUT CHECK PLOTS

2.Change the vehicle input like Cargo mass to 500kg and the Battery capacity of the vehicle as per given considerations and I have consider the battery module as ESS_PB25_IDEAL and the I have given random value for the no of modules is 30 and Voltage(V) nominal is 308 and mass 275kg and click on continue.

Change the driving cycle to CYC_FTP and go for RUN the program.

RESULTS

From the above results we can observe that the energy storage system state of charge (SOC) gradually decreases from the 100% to nearly to 60% and the emissions and overall ratio’s are constant.

OUTPUT CHECK PLOTS

3.To perform the Gradeability test with PRIUS Jpn defaults in file

Driving Cycle changed to CYC_FTP and the enable the Gradeability test

The Grade test advance options of the basics parameters like speed, time changed & all system enabled.Set the Gradeability and click on RUN.

RESULTS:

From the above results the energy storage system state of charge has reduces from the 70% to 50% when the speed of the vehicle minimum to nearly 0 kmph and when the vehicle is at rest position the state of charge is constant to nearly 52% when the vehicle starts travelling we can see that the soc is increasing and the speed at 10mph in 1second & Gradeability is at 0%.

Speed = 20mph for 3seconds & Gradeability = 9.1%

Speed = 30mph for 6seconds Gradeability =9.2%

Speed = 40mph for 8seconds Gradeability =10%

From the above results it has been seen that the speed increases with time then the Gradeability also increases beyond the certain limit the Gradeability gradually decreases.

CONCLUSION:

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 is performed well.Changing the battery capacity & Perform Gradeability test with PRIUS Jpn defaults in file are simulate with the results above.
