Week-3 Challenge: ADVISOR Tool
Q1. 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.
Ans - The Ev_defaults_in file vehicle is a purely electric vehicle. It is powered only by a motor of 75kw which delivers an efficiency of 92%.
- The cargo mass was changed to 500 kg resulting in an overall calculated mass of 1508 kg.
- Initial No. of cycles kept were one and the file was made to run.
Result :
- It is seen that the vehicle can travel a distance of only 11 miles.
- So in one cycle it can cover a distance of 17.76 km, which means if we increase the cycle by 2.53 times it should be able to cover a distance of 45km.
- The next step would be to increase the no. of cycles by 2.53 times
Result :-
- The distance travelled comes out to be only 25.7 miles i.e. 41.35 kms.
- A warning message also appears saying required distance exceeds the EV range.
CONCLUSION : Our vehicle cannot travel a distance of 45 km as this range exceeds the battery capacity.
SOLUTION : To increase the battery capacity.
Q.2 - In the above case, try changing the battery capacity and repeat the simulation.
Ans - The battery capacity was changed form 25 modules to 40 modules
- The program was run and the the following were the results.
- It covered a distance of 29 miles i.e. 46 kms.
- Increasing the battery module resulted in the increase in EV range.
CNCLUSION :- Simulation was repeated with change in battery module and the desired distance was achieved.
Q.3 - Perform gradeability test with PRIUS_Jpn_defaults_in file
Compare your results in table and conclude.
ANS - 
Prius is a hybrid electric vehicle which runs on both engine as well as on an electric motor.
Gradeability test has been peroformed for this vehicle as per below data.
| SR.NO | SPEED (MILES) | SPEED(KM) | DURATION(SEC) | GRADEABILITY(%) |
| 1 | 55 | 88 | 30 | 1.7 |
| 2 | 60 | 96 | 30 | 1.5 |
| 3 | 65 | 104 | 30 | 6.5 |
| 4 | 70 | 112 | 30 | 1 |
| 5 | 75 | 120 | 30 | 0.7 |
| 6 | 80 | 128 | 30 | 0.3 |
- Speed was increased at a rate of 5mph for a duration of 30 seconds
- Results are as follows.
1- 
2- 
3- 
4- 
5- 
6- 
CONCLUSION - In conclusion we can agree that as the vehicle speed increases the gradeability decreases respectively.
