Week-3 Challenge: ADVISOR Tool

Aim:

To Use the ADVISOR tool and simulate the following

1. For the EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel

for 45 km with an FTP drive cycle? Conclude your observations.

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

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in a table and conclude.

Model:

1. FTP Drive Cycle:

In the above model simulation of an Electric vehicle has done by changing the cargo mass to 500 and the remaining conditions are maintained as default.

In this motor 25 kW capacity of the battery has been used, which has 91% of efficiency which is shown in the above picture.

Federal Test Procedure CYC_FTP drive cycle is added to know the performance of the vehicle. In the above details distance traveled by the vehicle in a single charge is shown, these data is helpful to predict the performance of new vehicle were used with the same capacity of the motors.

A single drive cycle does not satisfy the given question, it does not complete 45Km in a single drive cycle.

From the above graph, we can see the state of charge of the battery, it has no charge so it cannot perform another drive cycle. so we are changing the no of cycles from 1 to 3.

To know the SOC (State of Charge) of the battery and to know how much distance the vehicle can travel, the count of drive cycle has increased to 3.

we can see the discharge of the battery in the below image, In the middle of the 3rd drive cycle the battery left no charge in it in and the total distance that the vehicle traveled is 41.4 Km.

The above graph shows the Vehicle can not travel 45 Km with the given drive cycle.

2. Change of battery capacity

By increasing a battery capacity 25Kw to 50Kw the vehicle can travel a distance up to 53.3km, this can be seen in the below image.

The Soc of the battery can be seen in the above image where it getting reduced drastically.

The above image shows that the vehicle has not completed its 4th driving cycle. It has some balance power through which we can have another drive cycle.

3.Gradeability Test

Toyota Prius has a gradeability of 6% which is quite less compared to the other commercial vehicles.

In this simulation, we are going to find how the change in gradeability can affect the vehicle Soc has been explained.

In this above simulation, the constant road grade we are assigning as 1.5, so that we can see the change in soc by changing the Gradeability of the vehicle.

The above SOC graph shows the value while the constant road grade is 1.5.

Here we are changing the gradeability from 6% to 8% and the results are shown below.

The above soc chart shows the effect of gradeabity on the performance of the vehicle.

Conclusion:

1. Vehicle can not travel 45 Km with the given drive cycle. It can travel to the required km only when we change the drive cycle.

2. changing the battery capacity can improve the performance of the vehicle.

3. changing the gradeability of the vehicle has an effect on the soc of the vehicle.
