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.

• Type advisor on command window.
• Set the unit system to metric system.
• Load file EV_defaults_in file.
• Change the cargo mass to 500 kg.
• Click on continue.

• Now choose the drive cycle to FTP drive cycle.
• Run the model.

• When we run the model with no of cycles = 1, the distance covered = 17.8km.
• We have to check whether the vehicle can travel 45km. Now run the model with no of cycles = 2.

• When we run the model with no of cycles = 2, the distance covered = 35.5km.
• We have to check whether the vehicle can travel 45km. Now run the model with no of cycles = 3.

• When we run the model with no of cycles = 3, the distance covered = 41.4km.
• We have to check whether the vehicle can travel 45km. Now run the model with no of cycles = 4.

• When we run the model with no of cycles = 4, the distance covered is not increasing beyond 41.4km.
• The distance covered is not increasing beyond 41.4 km eventhough we increase the no of cycles.
• Hence we can conclude that with the present specification and cargo mass of 500 kg, the vehicle cannot cover a distance of 45 km with FTP drive cycle.

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

• Change the no of battery modules from 25 to 30.
• Run the model with no of cycles = 3.

Thus by increasing the battery capacity (by increasing the no of modules from 25 to 30), the vehicle is able to travel a distance of 49.1 km. Tradeoff between battery capacity, no of driving cycles and SOC can be made.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

• Choose the file PRIUS_JPN_defaults_in
• Click on continue

• Choose the default drive cycle and no of cycles (i.e., 1)
• Choose grade options.

• Choose the required speed and also choose All systems enabled

• Run the model and observe the gradeability.

For different values of speed, run the model and note the gradeability. It is tabulated as below.

Speed (in mph)	Duration (in secs)	Gradeability (in %)
50	15	11.6
45	15	12.6
40	15	13.8
35	15	15.1
30	15	16.9
25	15	18.8
20	15	22.1
15	15	27

From the above, it can be concluded that as gradeability increases the speed decreases.
