Week-3 Challenge: ADVISOR Tool

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.

Ans: Aim: To verify whether the vehicle can travel for 45km with cargo mass of 500kg for EV_ defaults simulated vehicle in advisor tool

Procedure: 1. Download advisor tool from sourceforge.net

2. start the application and select load file and choose EV_defaults_in file

3. change cargo mass to 500 kg and press on continue

after pressing continue, change the driving cycle to cyc_FTP.

As the distance came for after simulation is 17.77km and need to increase the driving cycle by changing the number of cycles

By changing the cycles to 3 and clicking on run we will get following screen

Conclusion: Here we can see the battery energy droped and vehicle ran upto 41 km. So the vehicle can not run upto 45km as per simulation.

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

Ans: By changing the mod pack from 25 to 26 i.e incresing the module pack increases Ampere-hour capacity either by via increasing the voltage by series or increasing the current capability by parallel.

There was a significant improvement in distance cover (FTP cycle) and it is shown below

Conclusion:

Therefore from above cases..In inreasing the battery capacity, increases the mileage capability of EV vehicle.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Ans: Select the Drive train config and changeto prius_jpn

The Toyota Prius is somewhat unique among hybrids. It's a combination of both of the previous types and is known as a series-parallel hybrid. This is possible because of the Prius' power split device, a special gearbox that connects the gasoline engine, electric motor and generator together into one unit.

A car's gradability is its ability to climb slopes. Gradability is measured either in degrees or percentage. A 45 degrees gradient is equivalent to 100 per cent. Gradability is dependent on engine power, drivetrain type, gear ratio, weight, weight distribution, car's centre of gravity and traction.

A car's gradability study can be performed with speed, gear number, weight, angle..etc

A vehicle speed always varies based on user desire it is difficult to analyze the gradability with different speed.

But the load of the vehicle and slope of inclination will remain same for whatever the speed it is.

So it is best to analze the gradability with varying loads as Toyota vehicle gross weight for given model is 1790 kg by considering this as total weight we can analyze the performance by different cases using advisor Tool as follows:

We can add the weight of the vehicle by slecting 'add to current mass' such that we can increase the load of the vehicle as per user analysis

Conclusion: Hence by calculating the gradability with different load - the average gradability of the vehicle is found to be 17.55%
