Week-3 Challenge: ADVISOR Tool

1. AIM : Use ADVISOR tool and simulate the given questions.

2. OBJECTIVES OF THE PROJECT:

Give Answer of the below Questions to complete the Challange.

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.

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

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

   Compare your results in table and conclude.

3. BODY OF THE CONTENT:

Answers of the questions:.

Ans A : As per question, "EV_defaults_in" file selected, 500kg cargo mass, remaining all other at default conditions and FTP drive cycle selected. Can see in below images.

Fig1 : Drive cycle and Cargo mass

Fig2 : FTP drive cycle

`->` Here need to test vehicle travel for 45 km but 'FTP drive cycle has 17.77 km. So, no. cycle 3 selected to increas travel km.

Can be see in 'Fig2'.

Fig3 : Result figure

`->` As per fig3 we can see that vehicle taken arround 1hour 30min to cover 41.4 km and 25kwh battery drained, SOC is 0.

Result - FAILED, because it can not cover 45km with above condition.

Ans B : Now, changing the battery capacity and repeate the simulation.

Fig4 : Result Figure

`->` As per the fig4 we can see that vehicle taken arround 2hour to cover 49.1 km and 30kwh battery drained, SOC is 0.

Result - PASS. 30kwh battery are enough to travel 45km with above condition.

Ans C : Performing gradeability test with PRIUS_Jpn_defaults_in file and Comparing results in table and conclude.

Fig5 : Vehicle Input : PRIUS_Jpn_defaults_in

Fig6 : Gradability Data input PRIUS_Jpn_defaults_in

Fig7 : Result Figure PRIUS_Jpn_defaults_in

`->` As per Fig6, by changing the data of 'Speed' and 'Duration' the Gradability of vehicle tested. Others remain defaults.

Can see in below table.

Speed		Duration	Gradability
(mph)	(kmph)	(sec)	(%)
5	8	10	32.8
10	16	10	30.3
20	32	10	19.8
30	48	10	14.7
40	64	10	11.7
5	8	20	35.2
10	16	20	33.7
20	32	20	22.9
30	48	20	17.7
40	64	20	14.6
5	8	50	36.2
30	48	50	18.8
5	8	100	32.3

`->` Here tested a vehicle gradability with constant time and variable speed. We can see for 5 to 40 mph with 10 sec, gradability is decresing. As per the basic equation of Gradability is (Tractive force/Weigth), for the higher speed tourq is going to reduce means getting lower Tractive force, thats why getting lower gradability we can see that in above table.

`->` But if we increase the 'Duration' 10 to 20 or higher and remain 'speed' same as per last. We can see the Gradability % was increaed compair to its privious data. For other petrol-desile vehicles or non hybrid vehicles the gradability remain constant.

`->` Here this type of diffrence occurs because of vehicle has not only engine but its a hybrid vehicle that has engine+motor+generator+battery+etc. So, accordig to its work characteristic the vehicle gradability are affecting with respect to time duration.

4. CONCLUSION :

With this challange I unterstant the pourpose of the 'Advisor tool'. As a lerner, any one can learn and simulate data of the actual Vehicle or test own data, cycle with advantage of 'Advisor tool'. In this challange 'EV_default_in' and ' PRIUS_Jpn_defaults_in' tested and simulated results acording to questions.
