Week-3 Challenge: ADVISOR Tool
Challenge URL:- https://drive.google.com/drive/folders/16Sz6MVlmqAwTWNBcwjtdC-DmJtLnsRSO?usp=sharing
Task-1 To laod EV deafult in load file of advisor tool and run it at FTP drive cycle to check whether it can run for 45 km with 500 kg cargo load.
Observation:- After downloading the Advisor tool from internet and extracting it and opening it in matlab. typing advisor in command window will open the ADVISOR tool GUI and it will ask for the system to be modeled its unit must be in metric or us, so selecting metric in that and start the interfcae and then it will lead to the basic homepage of the tool where we can select the various vehicle from load file dropdown.
After selecting EV default first thing i do is that Changing its cargo load from 136 kg to 500 kg, Then after pressing continue we were asked to select the drive cycle from the dropdown box and there CYC FTP selected which means Federal Test Procedure and in that test procedure several key findout were like that:-
Time of test- 2477s
Distance travellled during test- 17.77 km
Max. speed achieved by vehicle - 91.25 km/hr
Avg. speed- 25.82 km/hr
Idle time- 360 s
No. of stops- 22
Max. acceleration/ deacceleration- 1.48 m/s^2
Avg acc./decel- 0.58 m/s^2
Now from this drive cycle model is run for 5 such type of cycle and to observe the behaviour of certain parameter of the vehicle we run the model.
Result:- We got to see that for 5 such drive cycle the max speed obtained is 89 km/ph and the vehicle travelled only 41.4 km of distance as the stored energy in the battery fall to zero from 1 after approx 5500 second and the vehicle will stop it operation. The vehicle will not be able to complete the distance of 45 km.
Task- 2
Observation:- Now since the battery is of Lead acid type and it is of ESS_PB25 so changing the no of battery module from 25 to 50 the rated voltage also changes from 308 V to 617 volts and mass from 275 kg to 550 kg just double of eralier parameter.
Now we run the same model with the Same drive cycle FTP for 5 cycles and by just changing in battery modules and observing the results
Results:- Now the vehicle can move upto a distance of 78.2 km here we have not considered the gradeability and acceleration test. The vehicle covered this ditance in the time duration of around more than 10500 sec. For 5 cycle the vehicle must run for 12385 sec but due to drainage of entire battery of the vehicle to Zero. The vehilcle could not pass the test for 5 cycles of FTP.
Task- 3:- To study the gradeability effect on the vehicle performance Prius_JPN
Observation:- In this vehicle there are Fuel converter (FC_PRIUS_JPN), Exhaust Aftertreat (EX_SI), Energy Storage (ESS_NIMH6), Motor (MC_PRIUS_JPN), Generator (CG_PRIUS_JPN), Transmission (TX_PRIUS_CVT_JPN), aheel and axle we are not changing any of the parameter which are as deafult and continuing to the next GUI will help us to take the drive cycle. Here i choose FTP75 as drive cycle and run the model for 3 cycles and perform the test and get to see the result as follows
Test-2 While in second test we have come back from the plot result model and turn on the gradeability test and entered in the gradeability option and i didn't make any changes in the basic parameter and mass parameter of the Grade test and only apply changes to the solution parameter by putting Grade lower bound value to 0 and Upper bound to 15 % and monitor the result as follows:-
Here we found that the gradeability at 88.5 kmpl speed is about 1.8% which was earlier 0.
Test- 3 In the third test what we have done is In the basic parameter we have cahnged the speed to 40 mph and time to 150 sec instead of 10 and then try to run the same program, we got result as follows
Here we see the gradeability is subjected to change as 2.5% also at the velocity of 64.4 kmph.
Test-4 In the fourth test we have just reverted back the speed to 55 mph and changed the duration to 120 sec instead of 150.
What we are seeing in the result is that the gradeability is incresed to 8.8% for 88.5m kmph.
So these were the test i performed on Toyota Prius Japan model.
