Week-3 Challenge: ADVISOR Tool
AIM:- Performing different simulations on ADVISOR tool
OBJECTIVE:- In this project we have to simulate different vehicle models under different defined conditions to observe their behaviour.
We have to do analyse three situations which are listed as follow:-
(i) checking the capacity of default ev model on the basis of SOC and distance travelled with a cargo mass of 500Kg.
(ii) Running the same default model by changing the battery capacity.
(iii) performing gradeability test on Prius model on different grades and creating a tabular data.
THEORY & PROCEDURE
ADVISOR stands for ADvanced VehIcle SimulatOR. It is a matlab/simulink based vehicle simution tool provided by NREL for doing simulations on differnt vehicle models under user based constraints to study the vehicle behaviours and optimise their performance. To start the ADVISOR we just run the command "advisor" but selcting the correct folder.
We will see a GUI of advisor initialization.
Then we choose a unit system and click on the "start " button.
01.
next we choose EV_defaults_in as our vehicle model and assign the caro mass as 500 Kg.
After clicking continue we will be defining the drive cycle for the given vehicle model.
Special focus should be gven to the number of drive cycles.
From the given drive cycle table we conclude that for one drive cycle of FTP :-
Distance covered= 17.7 Km
Duration= 2477 s
For present situation we have assumed gradeability to be absent.
we click on RUN to run the simulations and obtain the results.
RESULTS
1. For no. of cycles = 01
We see from the plot that battery has reached to 60% SOC that means the model has consumed 40 % battery energy in the present set up.
2. For no. of cycles = 02
Vehicle has covered a distance of 35.5 Km and consuming about 80% battery energy.
3. for number of cycles = 03
The vehicle is not able to complete the third driving cycle. it has reached its 0 soc and covered a total distance of 41.4 Km.
| No. of Drive cycle | Distance Covered(Km) | Battery SOC (%) |
| 01 | 17.8 | 60 |
| 02 | 35.5 | 20 |
| 03 | 41.4 | 0 |
Therefore, we conclude that the vehicle model can cover a maximum distance of 41.4 Km with the given specifications. Hence it can not go upto 45 Km.
2. Changing the battery capacity
Battery storage has three parametrs in which one is independent and other two are dependent.
First one is the number of modules , second is the total battery capacity and the last one is battery weight.
From our studies we conclude that for a single module battery capcity is about 12.3 V and weight is 11 Kg.
(i) battery module=30 , energy stored = 370 V
Vehicle model has enhanced its maximum distance covered limit .Now it can travel a distance of 49.1 Km.
(ii) Battery module= 20 , energy capacity= 247 V
Distance covered has been reduced so much that the model is not able to complete even 2 drive cycles and is 33.5 Km.
(iii) battery module = 35, energy capacity= 432 V
| Sl. No. | Battery module | Energy Capacity(V) | Distance Travelled (Km) |
| 01 | 30 | 370 | 49.1 |
| 02 | 20 | 247 | 33.5 |
| 03 | 35 | 432 | 53.2 |
From the above tabular analysis ,we got the insight that the distance covered of any simple Electric vehicle is directly proportional to battery capacity.
3. Gradeability test of PRIUS
Initialization the gradeability test by configuring the inputs.
For our first case we have fixed gradeability as 6 %. of speed= 22mph
case 2 grad 08 % speed 22 mph
case 3
gradeabiliy 10 % and speed 22 mph
case 04 grad 13 % speed 22 mph
case 05 grad 15 % speed 22 mph
case 06 grad 18 % speed 22 mph
The whole analysis is for 10 sec and for the speed of 22 mph.
| Sl. No. | Gradeability(%) | Distance Travelled(Km) | Fuel Consumption(L/100Km) |
| 01 | 06 | 17.8 | 11.4 |
| 02 | 08 | 17.7 | 13.5 |
| 03 | 10 | 17.3 | 15.9 |
| 04 | 13 | 14.4 | 20.3 |
| 05 | 15 | 11.5 | 24.7 |
| 06 | 18 | 08.0 | 32.8 |
So from the above analysis we conclude that:-
(i) as gradeability increase the distance covered by the model decreases
(ii) fuel consumption per 100Km increases with the increment of gradeability
CONCLUSION:-
From the done project we got the insights of application of ADVISOR tool and how to operate the software to accomplish our tasks. It gives us the place to simulate different vehicle models on various types of drive cycles.
It is a handy tool and can easily be operated to do the useful.
