Week-3 Challenge: ADVISOR Tool
1.
aim: to conclude the observations on the EV_defaults_in model file if the cargo mass is 500 kg with all other default conditions,can the vehicle travel with the of 45 kmph using FTP driving cycle
procedure:
1.open matlab and select directory path of the advisor tool
2.type the advisor command in the command prompt
3.in the load file select the EV_defaults_in file mentioned above
4.change the cargo load of the vehicle to 500 kgs with the other components keeping constant
5.select the continue button in order to select the driving cycle of the model
6.choose the driving cycle which is mentioned as FTP and run the model
from the above gui window for one driving cycle FTP 17.8 distance is travelled which in term consuming 40% of the energy from the battery
7.now run the model for 3 cycles of FTP and observe the results
from above results for 3 driving cycles of the battery is drained to 100% but the distance travelled is 41.4 km
conclusion:
from the above study we can assume that for three driving cycles of the FTP the battery energy is drained to 100% but the distance travelled is 42.1 km so that we can conclude this model cannot cover a didtance of 45 km with 1 full charge of the battery in order to achive it we have change conditons of its operation
2.
aim: using the charging of the battery capasity and repeat the simulation for the above mentioned model
procedure:
1. now using change in no of mods in the energy storage we can imporove the battery capasity of the model
2. for the previous study we have assumed 25 mods so we couldnt get the required distance travelled
3. now increase the mods to 30 and observe the results
from the above gui window for 30 mods in 3 driving cycles of FTP we are covering a distance of 49.1 km so we need to find what is the exact no mods needs to be incresed so we could get 45 km covered
4.now run the model using 27 mods of battery capasity and observe the results
from the above window we can obseve that for 27 mods we are covering a distance of 44.8 km which is just below the 45 km distance
5.now increse the mods to 28 so we could defintly achive the 45 km distance
from the above gui window for increase of 3 mods of battery capasity we can achive the 46.3 km diatance covered by running the vehicle for 3 FTP cycles
conclusion:
increase in the capasity of the battery automatically increase the milage of the vehicle from the above study by incresing 3 mods of battery capasity from 25 to 30 we can cover a distance of 46.3 km which is as per the requirement of the study
3.
aim: to Perform gradeability test with PRIUS_Jpn_defaults_in file .Compare your results in table and conclude.
procedure:
1. in the load file select the PRIUS_Jpn_defaults_in file
2.click on continue in order to enter the driving cycle gui to perform gradeablitiy test
3.now click on the grade options to get the below window
4.from the above window we can vary the speed ,duration ,gear ration in order to change the grade
5.we can also enable/disable the energy storge and fuel converter systems as per the reqirement
from the above window with the speed of 88.5 km/h gradeability is 8.9 now change the speed and again run the model
at 96.6 kmph the gradeablity is shown as 8.1 % now change the duration to 15 sec and run the model
with duration increasing from 10 to 15 sec at speed of 88.5 kmph the gradeability is 10.7 % similarly
at 96.6 kmph of 15 sec duration we are getting a gradeability of 9.9%
conclusion:
with the change in the parameters of duration and speed we can achive different gradeability values as follows
at 10sec duration
speed in mph gradebility
10 30.3%
20 19.8%
30 14.7%
40 11.7%
50 9.7%
