Week-3 Challenge: ADVISOR Tool

• INTRODUCTION OF ADIVSOR TOOL:-

• Advisor tool is developed in november 1994 by the National Renewable Energy Laboratory,it allows users to simulate and analyze convectional,advanced,light and heavy vehicles,including hybrid electrical and fuel cell vehicles.
• It is a set of models data and script text files for use with matlab and simulink.

• BENEFITS:-

• Estimate the fuel economy of vehicles that have not yet been built.
• Evaluate an energy management strategy for your hybrid vehicle's fuel converter.
• Learn about how conventional,hybrid or electrical vehicles use energy throughout their drivetrains.

• HOW TO START ADVISOR TOOL:-

• Launch MATLAB and first set default location folder to the advisor.
• Now on the command window of MATLAB type "advisor" and press enter.
• A new window will open and then select "metric" for unit and start ADVISOR.
• It will launch in a new window.

• Advisor tools have 3 windows:-

1. Vehicle input window
2. Simulation Parameter window
3. Results 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_defaults_in from the drop-down menu and changing Parallel_default_in to EV-defaults_in from vehicle input window.

• As shown in above,we are changing the cargo mass of vehicle with 500 Kg and keep all the parameters as it is and press continue.

• As shown in above image,we are changing the drive cycle with CYC_FTP and run the the simulation for 1 cycle.

• The distance traveled by vehicle is 17.8 km in 1 drive cycle.It is used 40%SOC

• Now,we are increasing drive cycle with 2 then run the simulation.

• We can see that our vehicle is driven for 35.5 km in 2 drive cycle.It is used 81% SOC.

• Now,increasing drive cycle with 3 and run the simulation.

• So, we can see that our vehicle is driven 41.4 km with 3 drive cycle and used 100% SOC.

• From above result,we concluded that minimum distance traveled by vehicle is 17.8km in 1 drive cycle.and maximum distance traveled by vehicle is 41.4 km in 3 drive cycle.
• Therefore EV_defaults can not travel distance of 45 km due to insufficient SOC.

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 storage.

• Here,"#of mod V nom" describes the battery capacity,so we will change the module number for the first box and we will see the changes in voltage and weight of the battery.

• Here,we are changing the battery modules with several number.and also changing the drive cycle input.
• But,for our case,we are tacking 28 modules of battery and we can see the volatge and weight is changing.

• As shown in above figure,we are changing the drive cycle with 3 and run the simulation.

• So,we get the results of the distance traveled by the vehicle is 46.3 km which is fullfill our requirement.

• We concluded that to cover 45 km distance a 28 modules 345-vol battery is required for our vehicle.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file. and Compare your results in table and conclude.

• As shown in above,we are selecting the PRIUS_JPN_defaults_in from drop down menu and select continue.

• Here,in above figure we are enable the gradeability test and go to grade options.
• In the grade option,we are changing the speed and duration.
• Also click all systems Enabled and press ok.
• Run the simulation and see the result of vehicle gradeability.

• RESULTS FOR DURATION - 10 SEC

• Speed - 20 Mph or 32.2 Kmph,Gradeability = 19.8%

• Speed - 25 Mph or 40.2 Kmph,Gradeability = 16.5%

• Speed - 30 Mph or 48.3 Kmph,Gradeability = 14.7%

• Speed - 35 Mph or 56.3 Kmph,Gradeability = 13%

• Speed - 40 Mph or 64.4 Kmph,Gradeability = 11.7%

• Speed - 45 Mph or 72.4 Kmph,Gradeability = 10.7%

• FOR DURATION - 10 SEC

SR NO	Vehicle speed (Mph)	Vehicle speed (Kmph)	Gradeability (%)
1	20	32.2	19.8
2	25	40.2	16.5
3	30	48.3	14.7
4	35	56.3	13.0
5	40	64.4	11.7
6	45	72.4	10.7

• RESULTS FOR DURATION - 20 SEC

• Speed - 20 Mph or 32.2 Kmph,Gradeability = 22.9%

• Speed - 25 Mph or 40.2 Kmph,Gradeability = 19.7%

• Speed - 30 Mph or 48.3 Kmph,Gradeability = 17.7%

• Speed - 35 Mph or 56.3 Kmph,Gradeability = 16.0%

• Speed - 40 Mph or 64.4 Kmph,Gradeability = 14.6%

• Speed - 45 Mph or 72.4 Kmph,Gradeability = 13.4%

• FOR DURATION - 20 SEC

SR NO	Vehicle speed (Mph)	Vehicle speed (Kmph)	Gradeability (%)
1	20	32.2	22.9
2	25	40.2	19.7
3	30	48.3	17.7
4	35	56.3	16.0
5	40	64.4	14.6
6	45	72.4	13.4

• From above tables,it clear that when vehicle speed increases there gradeability is decrease for both 10 sec and 20 sec duration.
• From above simulation,we concluded that if our vehicle speed is increasing than its gradeability is decreasing with time.
