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.

Solutions:

Download the advisor file from the link & extract it.

Now browse the file in the current directory& open 'advisor.m' file, the file will open in the script.

Run the file & start the advisor tool.

Select 'EV_default_in' in the file & change the cargo mass to 500 kg & select continue.

Now select 'CYC_FTP' drive cycle & RUN the simulation.

Output:

From the above output it is clear that the vehicle can't travel for 45 km with FTP drive cycle instead it can travel to only 11 miles i.e. 17.7 km.Also the state of charge (SOC) has decreased to 0 after 2500 seconds.

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

Solutions:

Open the advisor tool & change the battery capacity to 30 under the row Energy Storage-#of mod keeping all the parameters same.Select continue & RUN the simulation.

By changing the battery capacity to 30 we can see that the distance covered is the same but the state of charge has not decreased to 0 fully, instead it has some charge left.

Now, the battery capacity is changed to 40 keeping all the parameters same.

The output remain unchanged.

Thus we can conclude that by changing the battery capacity of the vehicle keeping rest of the parameters same , the distance travel by the vehicle will remain the same provided that the SOC will not get depleted instead it will still have some charge left.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Solutions:

In the advisor tool, select 'PRIUS_Jpn_defaults_in' file.

Keeping all the other parameters same by default click on continue.

Tick the Gradeabilty Test box & open Grade options, there speed is selected to be 55 mph by default.

Click on OK & Run the simulation.

Gradeability at 55 mph is 1.7 %

Now the speed is selected as 70 mph

So the gradeability at 70 mph is 0.9 %

Now the speed is selected as 35 mph

So the gradeability at 35 mph is 2.4 %

Gradeability is found at different speeds.

From above table, we can conclude that with increase in speed gradeability decreases.

Speed & gradeability are inversely proportional to each other.
