Week-3 Challenge: ADVISOR Tool
Use ADVISOR tool and simulate the following
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.
soln,
Open the ADVISOR TOOL from the matlab command window and select metric system, and load EV_default_in file and change the cargo weight to 500kg 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 to we can see an error occur as the EV ran out of battery for this type of drive cycle.
as to 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 to 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.
2. In the above case, try changing the battery capacity and repeat the simulation.
soln,
- In-Vehicle Input window we will change the capacity of battery form energy storage which will be open in 1st
- "#of mod V nom" describes the battery capacity, so we will change the module number of batteries from the first box and we will see that changes in voltage and weight of the battery.
- A new Simulation Parameter window will open, here we will change the drive cycle to 2 or 3, one at the time and run the simulation.
- After completing of simulation, we will see the result window where we observe the change in distance of vehicle travel.
- We can repeat this simulation by changing the battery module and the drive cycle.

| Battery Mod | Voltage | Km | Battery Weight |
| 26 | 321 | 35.5 | 288 |
| 27 | 333 | 35.5 | 297 |
| 28 | 345 | 35.5 | 308 |
Drive Cycle - 3
| Battery Mod | Voltage | Km | Battery Weight |
| 26 | 321 | 42.7 | 286 |
| 27 | 333 | 44.8 | 297 |
| 28 | 345 | 46.3 | 308 |
Battery Modules 28 for the 3 drive cycles, The distance traveled in 46.3km.
3. Perform gradeability test with PRIUS_Jpn_defaults_in file Compare your results in table and conclude.
soln,
Select 'Prius_JPN_default_in' file from the load file option to load the Prius model
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 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 5 mph to check the gradeability at different speeds.
Like that to assign the value on 5,10,15,20,25,30 & 35 is that values will be own the gradeability that values are,
| 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 table, to see that the Gradeability Decreases with Increase in speed, The Maximum gradeability during 5 Mph and Lowest Gradeability during 35 mph.
