Week-3 Challenge: ADVISOR Tool

EV LIVE BATCH:-21

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.

Ans:- According to the question, we have to open the ADVISOR tool.

so in order open the advisor tool, we have to follow the following steps:-

• In order to get the Advisor model of Advisor file, we have to download That Advisor file from the following link:-

https://sourceforge.net/projects/adv-vehicle-sim/

• Go to MATLAB main window & set the correct location or correct directory path for the ADVISOR folder as follows:

• then write 'advisor' in the command window of MATLAB & press enter.

• then set the Unit as 'Metric' & start the advisor.

• Acutually there are 3 windows of advisor such as:

1. Vehicle Input Window
2. Simulation Parameter Window
3. Results Window

• When we click on the Start option then we can see the Vehicle Input Window as folllows:-

• We can see that, the default loaded file is 'PARALLEL_defaults_in' & default Cargo mass is 136.
• so change the Load file from PARALLEL_defaults_in to EV_defaults_in & change the Cargo mass to from 136kg to 500 kg.

• Then click on Continue.
• Now a new window will pop up which is called as Simulation Parameter Window.

• Now change the Drive cycle from CYC_UDDS (default) to CYC_FTP by using the drop down menu.
• we can change the No. of drive cycle used for simulation by changing the values of '# of cycles'.

• Here we have taken 1 Drive cycle of CYC_FTP & then click on RUN.
• then a Results Window will pop up which will show results.

• Here we can see that the Vehicle covers 17.8 km distance by using 40% of SOC (means that after simulation SOC of battery pack is approximately 60%)

• Now click on Back option & again we will directed to Simulation Parameter Window.
• Then change the no. of drive cycle as 2 then click on RUN

• We can see that the Vehicle covers 35.5 km distance by consuming almost 82% SOC (after simulataion SOC will be 18%)

• Then click on Back option & then it will redirect to Simulation Parameter Window.
• then change the no. of drive cycle as 3 then click on RUN

• Here we can see that, Vehicle covers 41.4 km distance by consuming 100% SOC (means the SOC of the battery pack after simulation is 0%)

Table of results:-

No of Drive Cycle	Distance covered	SOC of Battery pack after Simulation
1	17.8 km	60 %
2	35.5 km	18 %
3	41.4 km	0 %

Conclusion:-

• The minimum distance covered by the vehicle is 17.8 km by consuming the almost 40% of SOC when we had used 1 drive cycle.
• the maximum distance covered by the vehicle is 41.4 km by consuming 100% SOC when we had used 3 sets of CYC_FTP Drive cycles.
• We can simply say that, For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, the vehicle cann't travel 45 km by using CYC_FTP drive cycle due to insufficient SOC (State of Charge)

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

Ans:- According to the question, we have to change the battery capacity & repeat the simulation. which means that we have to kept the Load file as EV_defaults_in & Cargo mass as 500 kg as follows:

• Then we can change the Battery capacity by change the no of Modules used in the battery pack.
• we can change the no. of Modules used in Battery pack by changing 1st box of ' #of mod V nom '

• as we have seen from the previous results that when we had used 1 CYC_FTP drive cycle then the vehicle covers upto maximum 17.8 km which is very less than 45 km.
• so here we will take the No of modules used in battery pack as 26,7,28,29,30 etc & incraese the no. of drive cycles as 2,3,4 etc. to see when the vehicle is able to cover 45 km to overcome 45 km.

Observation:-

(i) Energy storage system as 26 modules & 2 drive cycles:

(ii) Energy Storage system with 28 modules & 2 drive cycles:-

(iii) Energy storage system with 30 Modules & 2 drive cycles:-

(iv) Energy storage system with 26 modules & 3 drive cycles:-

(v) Energy storage system with 28 Modules & 3 Drive cycles:-

Table of Observation:-

No.of Modules	No.of Drive Cycle	Voltage (Volt)	Distance (km)	Weight of Battery pack (kg)
26	2	321	35.5	286
28	2	345	35.5	308
30	2	370	35.5	330
26	3	321	42.7	286
28	3	345	46.3	308

Conclusion:-

• Here we can see that the EV_defaults_in vehicle can overcome 45km by using 28 no.of modules in the battery pack & using 3 CYC_FTP drive cycles.
• so we can increase the range of Electric Vehicle by increasing the battery capacity & no.of drive cycles.
• By using 28 Modules & 3 drive cycles, the vehicle travels upto 46.3 km

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Ans:- According to the question, we have to check Gradeability test with 'PRIUS_Jpn_defaults_in' load file.

Steps:-

• Change the Load file from PARALLEL_defaults_in to PRIUS_Jpn_defaults_in

• Then click on Continue option.
• then Simulation Parameter Window will pop up.
• Now click on Gradeability test & click on Grade option then a new dialog box will opwn as follows:-

• In order to perform Gradeability test, we have to change the time duration & speed at different time.
• Now select "All system Enabled"
• then click on ok

• Here we have taken the Time duration as 10sec & we have to change the s[eed of the vehicle during 10sec time duration.
• Here unit of time duration & speed have taken as sec & mph (miles per hour) respectively.

(A) Time duration is 10sec:-

(i) Speed of vehicle is 20 miles per Hour or 32.2 kmph:-

• Here the Gradeability of vehicle at 32.2 kmph is 19.8%

• Here Gradeability of vehicle at 48.3 kmph is 14.7%

(iv) Speed is 35 mph or 56.3 kmph:-

• Here Gradeability of vehicle at 56.3 kmph is 13%

(v) Speed is 40 mph or 64.4 kmph:-

• Here Gradeability of vehicle at 64.4 kmph is 11.7%

• Here Gradeability of vehicle at 32.2 lmph is 22.9%

(ii) Speed of vehicle is 25 mph or 40.2 kmph:-

• Here Gradeability of vehicle at 40.2 kmph is 19.7%

(iii) Speed of vehicle is 30 mph or 48.3 kmph:-

• Here gRadeability of vehicle at 48.3 kmph is 17.7%

(iv) Speed of vehicle is 35 mph or 56.3 kmph:-

• Here Gradeability of vehicle at 56.3 kmph is 16%

(v) Speed of vehicle is 40 mph or 64.4 kmph:-

• Here Gradeability of vehicle at 64.4 kmph is 14.6%

Observation Table:-

• For Time duration of 10sec:-

Speed of Vehicle (kmph)	Time Duration (sec)	Gradeability (%)
32.2	10	19.8
40.2	10	16.5
48.3	10	14.7
56.3	10	13
64.4	10	11.7

• For Time duration of 20sec:-

Speed of Vehicle (kmph)	Time Duration (sec)	Gradeability (%)
32.2	20	22.9
40.2	20	19.7
48.3	20	17.7
56.3	20	16
64.4	20	14.6

Conclusion:-

• Here we have taken speed of vehicle as 32.2 kmph, 40.2 kmph, 48.3 kmph, 56.3 kmph & 64.4 kmph for two different time duration of 10sec & 20sec
• Then we can see from above tables that at constant Time period, when Speed of vehicle increases then the Gradeability of vehicle decreases & vice-versa
• we also observed that, at constant speed when time duration increases then the Gradeability of vehicle increases & vice-versa
• Practically, maximum gradeability of a vehicle can be 45%.
• We have sucessfully perfomed the Gradeability test for PRIUS_Jpn_defaults_in Loded vehicle.
