Week-3 Challenge: ADVISOR Tool
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 wants to see the following result before the implementation of the model
- For EV defaults in file if cargo mass is 500kg with all other default conditions can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.
Load the ADVISOR TOOL from the mat lab command window and select metric system and load EV default in the 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 ran 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 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 kilometers but will be short by 3.2 kilometers.
- In the above case try changing the battery capacity and repeat the simulation
The current battery capacity is kept as 25 we need to increase the battery pack capacity so that the vehicle can run more than 45 kms.
So for this we will increase the battery capacity from 25to 45
By increasing the battery cpacity we can see that the range has been increased to 53.3km which is more than the required range we need
- Perform gradeability test with PRIUS_ JPN_ default in file from the load file option to load the Prius model
Hit continue and select the Grade option 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 systems 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 5mph to check the gradeability at different speeds
After running the Prius model with different speeds we can check the gradeability percentage we need to take the values at different speeds 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 speed the maximum gradeability during 5 mph and lowest during 35 mph
