Week-3 Challenge: ADVISOR Tool

EV 17TH LIVE BATCH

ADVISOR:

A model written in the widely used MATLAB/Simulink software environment. This is a tool stands for 'Advanced vehicle simulator' which is used to model different types of vehicles such as some IC engine based and electric vehicles, hybrid vehicles and fuel cell-based vehicles, this tool is very useful in case of user-defined powertrain or vehicle dynamics and want to see the following results before the implementation of the model.

1.Que:

Load the ADVISOR TOOL from the matlab command window and select metric system, and load EV_default_in file and change the cargo weight to 500 and keeping the remaining variables same and hit continue to load the drive cycle page.

for our requirement, we need to use FTP based cycle select the following and hit 'run'as we can see an error occur as the EV run out of battery for this type of drive cycle.

as we need total distance covered to be 45 kilometers and this drive cycle can only complete 17.8 so we need more than 1 drive cycle to complete more than 45 kilometers. so we can use 3 drive cycles.

as we can see a warning sign pops up which means that the distance is more than the range of the current battery pack so the vehicle can not travel 45 kilomters but will be short by 3.2 kilometers.

2.Que:

In the above case, try changing the battery capacity and repeat the simulation. the current battery capacity is kept at 25 we need to increase the battery pack capacity so that the vehicle can run more than 45 kms. so far this we will increase the battery capacity from 25 to 45 by increasing the battery capacity we can see that the range has been increased to 53.3 km which is more than the required range we need.

3.Que:

Hit continue and select the grade options to open the grade test options in this we need to change the option which will include both fuel and energy storage system, hence we will select all system to enable and in basic parameters the speed of the vehicle can be controlled we need to change the speed from 5-35 mph with an increment of 5 mph to check the gradeability at different speeds after running the prius model with different speeds we can check the gradeability percentages, we need to take value at different speed and tabulate the information.

speed(MPH)         Gradeability

5                             32.8

10                           30.2

15                           24.4

20                           19.8

25                           16.5

30                           14.7

35                           13

from the above table, we can see that the gradeability decreases with increase in speeds the maximum gradeability during 5 mph and lowest gradeability during 35 mph.
