Week-3 Challenge: ADVISOR Tool
Use ADVISOR tool and simulate the following
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.
Open the ADVISOR Tool, set the load file to 'EV_defaults_in'
Cargo mass is 500 kg then ADVISOR Tool
Loading file 'EV_defaults_in in the ADVISOR Tool and the cargo mass input as 500kg.
On clicking continue the 'Drive cycle window' appears selecting 'CYC_FTP' to the drive cycle.
Each FTP drive cycle lasts for a time period of 2.4 sec and a distance of 17.8kmph. In order to verify if the vehicle can travel for 45km, we have to consider the number of cycles to be 4
ON clicking RUN. the results are obtained
The results figure window shows the graphs for velocity soc emission and overall ratio.
Conclusion: Hence, For the EV_defaults_in file, if the cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle, and results are obtained.
2. In the above case, try changing the battery capacity and repeat the simulation.
Loading file 'EV_defaults_in' in the ADVISOR TOOL and set the cargo mass as 500kg. In this case, we will increment the number of battery modules by 25. hence the total is 50 resulting in a nominal voltage of 617v.
On clicking continues the drive cycle window appears. we are selecting 'CYC_FTP' to be the drive cycle.
Each FTP drive cycle lasts for a time period of 2477 seconds and a distance of 17.77km.
In order to verify if the vehicle can travel for 45km, we have considered that the number of cycle is 4.
On giving RUN command.
CONCLUSION: From the above graph of SOC it is evident that the state of charge remains at 10.75% even after completing 4FTP drive cycles. Also under the fuel consumption tab, the distance travelled is displayed as 71.1 km. Hence in the previous case where the distance travelled was 41.4 km. hence by increasing the number of battery modules from 25 to 50, we can make the EV car easily travel more than 45 km.
3. Perform gradeability test with PRIUS_Jpn_defaults_in file
Compare your results in table and conclude.
Loading 'PRUS_Jpn_defaults_in' in the ADVISOR TOOL.
On clicking the continues button the 'drive cycle window' appears. the drive cycle selected is 'CYC_UDDS'.The gradeability test toggle is selected. On clicking the Grade options button, we can set the speed and duration as required. also, other parameters can be changed.
CASE:1.
SPEED = 50mph and duration =10 seconds. all other parameters are set as default.
CASE:2.
SPEED = 75 mph and duration =10 seconds. all other parameters are set as default.
CASE:3.
SPEED = 100 mph and duration =10 seconds. all other parameters are set as default.
CASE:4.
SPEED = 100 mph and duration =20 seconds. all other parameters are set as default.
CASE:3.
SPEED = 100 mph and duration =60 seconds. all other parameters are set as default.
| Case | Duration (sec) | Speed (mph) | Speed (kmph) | Gradeability (%) |
| 1 | 10 | 50 | 80.5 | 9.7 |
| 2 | 10 | 75 | 120.7 | 5.3 |
| 3 | 10 | 100 | 160.9 | 1.3 |
| 4 | 20 | 100 | 160.9 | 2.6 |
| 5 | 60 | 100 | 160.9 | 3 |
