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:-

*The ADVISOR Tool model is shown below ,

*Drive cycle: CYC_FTP;

*No of cycle : 3;

* Result of ADVISOR Tool Model :-

Conclusion :-

• Thus we can see that for 3 no. of cycles at the given conditions the vehicle can travel only 25.70 mph & when converted to Km then it travels 41.3Km.
• If we increase the no. of cycles , then the vehicle can travel above 45Km.

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

* The ADVISOR Tool model is shown below ,

* In above simulation we have changed the battery capacity to 25 to 50V.

* Result of ADVISOR model ,

Conclusion :-

• We can see that by increasing battery capacity the vehicle can travel for more than 33.1 mph & when when coverted to Km then it travels 53Km in the same no. of drive cycles.
• Similarly when we decrease the battery capacity the vehicle travels lesser distance.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude :-

* The ADVISOR Model is shown below ,

* Speed : 50mph

* Fully Electric :-

* Result of ADVISOR Model ,

*Speed : 50mph

*Hybrid ,

* Result of ADVISOR Tool ,

*Speed : 50mph

*IC Engine ,

* Result of ADVISOR Tool ,

Conclusion :-

• At 50mph Gradeability for fully electric vehicles is 9.7% resp.
• At 50mph Gradeability for hybrid vehicles is 10.8 % resp.
• At 50mph Gradeability for IC engine vehicles is 2 % resp.

* Now again do the same simulation by changing the speed to 25mph :-

* Speed : 25mph

* Fully Electric ,

* Result of ADVISOR Tool ,

* Speed : 25mph

*Hybrid ,

* Result of ADVISOR Tool ,

*Speed : 25mph

IC Engine ,

*Result of ADVISOR Tool ,

Conclusion :-

• At 25mph Gradeability for fully electric vehicles is 17.6 % resp.
• At 25mph Gradeability for hybrid vehicles is 17.6 % resp.
• At 25mph Gradeability for IC engine vehicles is null % resp.

Comparision Table :-

Conclusion :-

• The required problems have been solved and justified with appropriate results.
• The cargo mass change resulted in the change in the overall weight of the system and initial battery voltage is not sufficient to travel 45 km.
• Therefore, the voltage of the battery was increased to 50 V to reach the desired distance, but this is a compromise with the overall weight.
• Since, to achieve the distance the weight of the system has to be increased. Gradeability test on Prius is conducted by varying the speed from 50mph to 25mph and is observed that the speed and gradeability are inversely proportional to each other.
