Week-3 Challenge: ADVISOR Tool
Task-1
Consider file : EV_defaults_in , Cargo mass is 500 kg and battery modules 25 no’s , 308 volts
Consider FTP drive cycle
OUTPUT: For one drive cycle
For one drive cycle, vehicle reaches to 17.8 KM and SOC reduces from 100% to 60%
No of drive cycles = 02
For two drive cycles, vehicle reaches to 35.5 KM and SOC reduces from 100% to 20 %
No of drive cycles = 03
For three drive cycles, vehicles reaches to 41.4 KM but it exceeded EV range( warning show on output) SOC reaches to zero at 5500 sec , so With battery vehicles will travel approx. 41KM
Conclusion: My observation on above results to conclude that vehicle can’t travel 45KM with FTP drive cycle . SOC reduced to zero when vehicle reaches to 41.4KM (Mean vehicle can travel approx. 41KM with FTP drive cycle)
TASK:2
Consider the file : EV_defaults_in , Cargo mass is 500 kg and battery modules 30 No’s ,370 volts
Consider FTP drive cycle
No of drive cycles = 01
For one drive cycle, vehicle reaches to 17.8 KM and SOC reduces from 100% to 65%
No of drive cycles = 02
For two drive cycles, vehicle reaches to 35.5 KM and SOC reduces from 100% to 30 %
No of drive cycles = 03
For three drive cycles, vehicles reaches to 49.1 KM but it exceeded EV range( warning show on output) SOC reaches to zero at 7200 sec , so With battery vehicles will travel approx. 49 KM @ 30 no’s of battery modules.
Conclusion: From the above results, Vehicle can travel the 45 KM with FTP drive cycle is possible when battery modules 30 no’s.

Conclusion : From the camparision table, increases the required power with increasing the gradeability. SOC also decrease with increase in gradeability and speed also decreases with increases the gradeability ( at gradeability 8.5 % speed curve starts shows the variation to actual and required).
