Week-3 Challenge: ADVISOR Tool

SOLUTION 1.

Objective:-

To verify wheather the car model ''EV_default_in'' , can travels a distance of 45KM with a pay load of 500KG in FTP drive cycle.

TOOL USED:-

1)ADVISOR tool used that can give us result in a GUI platform.

2)Download this tool from online and extract the files, Now in MATLAB Add the ADVISOR FOLDER to its current Directory.

3)Then in the Command window write the command "advisor" and press enter.This adds all the Files & Folder of ADVISOR Tool into Basework space.

4)A new GUI platform gets open.

Select the "Metric" Units and Click On "Start" the ADVISOR Tool.

PROCESS:-

• After Clicking on"Start", it get default open as PARALLEL_defaults_in file model parameters we need to change it to EV_default_in.
• Now , without changing any parameter we have to change default cargo weight from 136KG to 500KG.

• Then press continue & move on to next page.
• Here change the default drive cycle from UDDS to FTP cycle. The cycle gets reflected in the left side.
• All Details of FTP cycle is given left-down in a box. If we want acceleration test & Gradeability test means, click the check the check boxes and run.

RESULT:-

We got the result of a distance of 17.8KM for a single drive cycle.

For 2 drive cycle we are getting distance of 35.5KM.

For 3 drive cycle we are getting distance of 41.5KM

For 4 drive cycle we get distance as same as 41.4KM as battery SOC drains fully as we are seeing in second plot of result.

CONCLUSION:-

So, from the result of 4 time FTP cycles we conclude that this vehicle doesnot travels 45KM in single charge.

Vehicle Model : EV_defaults_in

Drive cycle type : FTP

No. of drive cycle Distance(KM)

1 17.8

2 35.5

3 41.5

4 41.4

SOLUTION 2.

Same above case with a change in battery performance.

OBJECTIVE:- To increase the battery capacity so that vehicle can travel 45KM in a single charge.

PROCESS:-

• Come back to Home Page of the model.
• Change the battery maximum power capacity from 25KW to 30KW for same cargo weight 500kg.
• Then run in FTP cycle of first cycle, we are getting distance of 17.8KM.

• For 2 no. of cycle we get 35.5KM

• For 3no. of cycle we get 49.1KM.So, we exceed 45KM in 3no. of cycle.

• For 4no. of cycles we get again 49.1KM as battery get fully drained.

CONCLUSION:-

Thus we can use the vehicle for 45KM in single charge of 30KM battery maximum power capacity.

4 49.1

SOLUTION.3

GRADEABILITY TEST WITH PRIUS_Jpn_defaults_in file.

OBJECTIVE:-

TO TEST THE GRADEABILITY WITH DIFFERENT SPEEDS AT ELEVATIONS.

CONDITIONS:-

MODEL:PRIUS_Jpn_defaults_in

DRIVE CYCLE:UDDS

PROCESS:-

• So in this case the gradeability from 50KMPH to 100KMPH are taken as consideration.
• We have to change the speed in grade option of gradeability test.
• Here i taken 50kmph to 100Kmph, by changing the speed we have to get the gradeability % for each velocity.

Then click OK and Run the model.

CONCLUSION:-

We are getting gradeability % varies from 50kMPH to 100KMPH. This can be shown in table below.

KMPH MPH GRADEABILITY

50 31.07 2.5

55 34.18 2.5

60 37.27 2.5

65 40.34 2.4

70 43.54 2.2

75 46.94 2.1

80 49.72 2.0

85 52.82 1.8

90 55.93 1.7

95 59.04 1.5

100 62.15 1.4

From this we can conclude that gradeability gets decreases as speed inceases i.e speed get increases as steep decreases.
