Week-3 Challenge: ADVISOR Tool

SSanju Siby2 Nov 2021

ADVISOR TOOL

1. EV_defaults_in

AIM: To load EV_defaults_in file, change the cargo mass value and observe the results.

OBJECTIVE: Change the cargo mass to 500kg, run the vehicle in FTP cycle for 45km and observe whether it is able to complete the distance.

ADVISOR tool:

Downloaded the tool and ran the program.

Started the tool and loaded the EV_defaults_in file

Changing the cargo mass to 500kg and keeping all the other vehicle parameters to default.

Then continued to the simulation parameter box. The FTP drive cycle is chosen, and since we need the simulation to run for more than 45 kms, the cycle is repeated three times.

17.77 * 3 = 53.31kms.

Run the simulation.

RESULTS

As the warning message shows, the vehicle battery charge ran out before completing the simulation. The distance travelled was 41.4 kms. Thus failing our aim of the vehicle running 45 kms.

CONCLUSION

The increase in the cargo load from 136 to 500kg increased the power requirement from the vehicle significantly, thus consuming more power to move. This leads to the battery charge running out. Thus this configuration of EV will not be able to run with this load without increasing the battery capacity.

2. Increasing the battery capacity for the simulation

ADVISOR TOOL

Increasing the number of energy storage(battery) modules from 25 to 28.

RESULTS

The increase in battery modules achieved the 45 km limit. The simulation ran for 46.3 kms.

CONCLUSION

The objective of 45 kms was achieved by adding three modules of energy storage.

3. Gradeability test with PRIUS_Jpn_defaults_in file

AIM: To perform gradeability test with PRIUS_Jpn_defaults_in file

OBJECTIVE: To perform a gradeability test with different grades and analyse the results.

ADVISOR TOOL:

Loading PRIUS_Jpn_defaults_in file into the tool

In the simulation parameters section, we are selecting the gradeability test. In the grade options we can select the grade %, speed and time. Here we are considering 5 cases with increasing garde. Speed and time is kept constant. The drivecycle chosen is UDDS with a distance of 11.99 kms and 1369secs time. All the other parameters of the simulation and vehicle is maintained in default settings.
