Week-3 Challenge: ADVISOR Tool

1. AIM

Use the ADVISOR Tool and understand the working of the tool and how to simulate different models.

2. OBJECTIVES

1. To give different inputs and check how it affects the outputs.
2. To Simulate a model to check if the vehicle can meet the given requirements.
3. To modify some parameters like changing the battery so that the vehicle meets the given requirements.
4. To perform gradeability test with Prius by changing the speed and time.

3. METHOD

3.1 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?

We change the cargo mass to 500kg	We change the drive cycle to FTP

• We run the simulation for 1 cycle and get the output.
• The distance covered is 11 miles that is 17.7 km.
• But since we need the vehicle to travel 45km we check for more cycles.

	For 1 cycle
	For 5 cycles
	For 10 cycles

• Even after 10 cycles, we get the maximum distance of 25.7 miles which is 40.23 km.

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

• We get to know that the vehicle won't run for 45 km on default settings.
• So to increase the range we try changing the battery and run the simulation for 3 cycles.
• The default battery used was ESS_PB25, and we change it to ESS_PB65_FocusEV and ESS_PB85.
• Both these batteries give a similar output.
• After the simulation is run, the vehicle travels the required distance.
• Hence we can say that once the battery capacity is increased, the range of the vehicle also increases.

Fig. Below shown is ESS_PB65_FocusEV
Fig. Below shown is ESS_PB85

• The distance travelled is 33.1 miles that is 53.26 km which is more than the required range.

3.3 Perform gradeability test with PRIUS_Jpn_defaults_in file

Fig. PRIUS MODEL

• We open the Prius model and we then change the speed and time to perform the gradability test.
• We can see after performing the test that the gradeability increases as we give more time for the vehicle to climb the hill.
• We initially test for 55 mph for 10 secs and 20 secs.
• After the simulation is run we get the gradeabilty is 9.2% for 10 secs and it changes to 11.8% for 20 secs.
• We perform a second simulation at 65 mph for 10 secs and 20 secs.
• Similar to the first test we get that the gradeability 7.5% for 10 secs and it changes to 9.8% for 20 secs.
• The results of the simulations are shown below.

For 55 mph at 10 secs
For 55 mph at 20 secs
For 65 mph at 10 secs
For 65 mph at 20 secs

4. LEARNING OUTCOME

1. Learned the use of ADVISOR Tool and understand the basics of the tool.
2. Learned how we can edit the different parameters of the models.
3. Learned how to test the gradeability of the vehicle.

5. CONCLUSION

• It is necessary to change the battery to improve the range of the vehicle.
• As the time required for the vehicle to climb the hill increases the gradeability also increases.
