Week-3 Challenge: ADVISOR Tool

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.

Objective: To analysis the battery SOP of FTP drive cycle for EV defaults model in Advisor Tool having cargo mass of 500kg.

Procedure:

1. open matlab and load Adivsor tool.
2. In Adivsor tool load the EV defaults model.
3. Change the cargo mass to 500 kgs and run the file.
4. Run the file and observer the distance and battery soc.

above figure shows Cargo mass has changed to 500kgs and Loaded file is EV_defaults_in.

For one cycle of FTP, total 17.77 kms of distance covered. To cover 45 kms,it require 3FTP cycles.

From above graphs, it is clear that battery soc reaches to 0 percentage and total distance covered is 41.4 kms.

Therefore EV default model with 500kg cargo mass will not support to cover 45km distance. As batteries have completely discharged.

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

Objective: To analysis the battery SOP of FTP drive cycle for EV defaults model in Advisor Tool having cargo mass of 500kg.

Procedure:

1. open matlab and load Adivsor tool.
2. In Adivsor tool load the EV defaults model.
3. Change the cargo mass to 500 kgs and run the file.
4. Increases the number of Battery modules to 50 having voltage of 550v.
5. Run the file and observer the distance and battery soc.

Above figure shows, battery module has incresed to 50.

For one cycle of FTP, total 17.77 kms of distance covered. To cover 45 kms,it require 3FTP cycles.

From above figure, it can be conculded that Battery power is now sufficient to cover distance of 45kms.

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

Aim: To perform gradeability test with PRIUS_Jpn_defaults model.

Procedure:

1. open matlab and load Adivsor tool.
2. In Adivsor tool load the PRIUS_Jpn model.
3. Select CYC UDDS drive cycle.
4. Select Gradeablity tab and change speed and time in gradeablity pop-up window and run the model.
5. For Different values of speed observer the gradeability performance of the vechicle.

Above figure shows prius_jpn default model.

In above figure, Drive cycle is changed to CYC UDDS.

Case_1: Vechicle speed 60mph and duration 15 secs.

From above figure gradeablity is 1.5% and speed is 96.6kmph

Case 2: Vechicle speed 70mph and duration 15 secs.

From above figure gradeablity is 0.3% and speed is 112.7kmph

Case 3: Vechicle speed 80mph and duration 15 secs.

From above figure gradeablity is 0.3% and speed is 128.7kmph

From above figure gradeablity is 0.3% and speed is 128.7kmph

Conclusion:

S.no	Duration	Speed	Gradeablity
1	15s	60mph	1.3%
2	15s	70mph	1%
3	15s	80mph	0.3%

From above table it can be concluded that as speed increase Gradeablity of Vechicle decreases.
