Week-3 Challenge: ADVISOR Tool
Ans 1) For EV_defaults_in file cargo mass is set 500 KG leaving other condition as default to check whether it can travel 45 Km using FTP drive cycle.
1st case – Using 1 Drive Cycle.

2nd case – Using 2 Drive Cycle.
OBSERVATION OF CASE – 2

82 % |
3rd case – Using 3 Drive Cycle.
OBSERVATION OF CASE – 3

|
41.4 Km |
100 % |
CONCLUSION:
From the above observation we can understand that with single FTP drive cycle the vehicle can only go 17.7 Km but that does not mean that if we increase the number of drive cycle the vehicle will go 45 Km. The reason is that battery is getting discharge at 41.4 km hence the vehicle cannot travel for 45 Km.
Ans 2) For the above case battery capacity is changed for the same simulation.
In all the below cases 3 FTP Drive cycles are use together.
Case – 1 Number of Battery Modules = 26:
In the above images red underlined it can be observed that the number of battery modules are 26 with Nominal voltage of 321 Volts. The weight of battery pack is 286 Kg.
OBSERVATION FOR CASE – 1:
|
DISTANCE TRAVELLED (Km) |
BATTERY SOC USED (%) |
NO. OF BATTERY MODULES |
NO. OF DRIVE FTP CYCLE USED |
|
42.7 |
100 |
26 |
3 |
So, from above observation it is cleared that the vehicle cannot travelled 45 km with 26 modules of battery as the battery is getting discharged.
Case – 2 Number of Battery Modules = 27:
In the above images it can be observed that the number of battery modules are 27 with Nominal voltage of 333 Volts. The weight of battery pack is 297 Kg.
OBSERVATION FOR CASE – 2:
|
DISTANCE TRAVELLED (Km) |
BATTERY SOC USED (%) |
NO. OF BATTERY MODULES |
NO. OF DRIVE FTP CYCLE USED |
|
44.8 |
100 |
27 |
3 |
So, from above observation it is cleared that the vehicle cannot travelled 45 km with 27 modules of battery as the battery is getting discharged.
Case – 3 Number of Battery Modules = 28:
In the above image it can be observed that the number of battery modules are 28 with Nominal voltage of 345 Volts. The weight of battery pack is 308 Kg.
OBSERVATION FOR CASE – 3:
|
DISTANCE TRAVELLED (Km) |
BATTERY SOC USED (%) |
NO. OF BATTERY MODULES |
NO. OF DRIVE FTP CYCLE USED |
|
46.3 |

28 |
3 |
So, from above observation it is cleared that the vehicle has travelled more than 45 km with 28 modules of battery as the battery capacity has increased sufficiently.
Ans 3) Gradeability test for PRIUS_Jpn_defaults_in file.
Case - 1 - When all system are enabled - Time - 10 Seconds:
In the above image it can be observed that "All system are enabled". In the above menue speed is increased from 1 mph to 62.5 mph step by step with difference of 5. Below are the observation for gradeability with diffrent speeds in mile per hour.

OBSERVATIONS:
From above observation it can be observed that the gradibilty decreases with increase in speed and with change in time there is chnage in gradeability.
