Week-3 Challenge: ADVISOR Tool
Question no 1:
Advisory tool menu in Matlab
Open the advisor tool and set the load file to EV_defaults_in
Components to motor controller the above table before giving the mass of 500kg the below advisory tool after giving mass 500kg
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.
the CYC_UDDS is before changing to CYC_FTP
The below advisor tool after changing to CYC_FTP and the waveform is obtained.
Each FTP drive cycle lasts for a time period of 2.4sec 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 windows appears the graphs for velocity soc emission and overall ratio are displayed.
Conclusion: Hence for the EV_defaults_in file, if cargo mass is 500kg with all other default conditions, can the vehicle travel for 45km with FTP drive cycle and results are obtained.
Question no 2:
Loading file EV_default_in in the advisor tool and set the cargo mass as 500kg.in this casewe will increment the number of battery modules by 15 hence the total is 40 resulting in a normal voltage of 493v
On clicking continues the drive cycle window appears. 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 cycle is 4
after running
The results figure window appears the graphs for velocity SOC Emission and overall ratio are displayed.
conclusion
From the above graph of SOC it is evident that the state of charge remains at 20% even after completing 4FTP drive cycles. Also under the fuel consumption tab, the distance traveled is displayed as 53.3 km. Hence by the previous case where the distance traveled was 41.4 km. hence by increasing the number of battery modules from 25 to 40, we can make the EV car easily travel more than 45 km.
Question no 3
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 = 60mph=96.6kmph and duration =20 seconds. all other parameters are set as default.
CASE:2. SPEED=70 mph =112.7kmph and duration =20 seconds. All other parameters are set as defaults.
CASE:3. SPEED= 80mph=128.7kmph and duration=20 seconds. all other parameters are set as defaults.
CASE:4. SPEED =90mph=144.8kmph and duration =20 seconds. All other parameters are ser as default.
CASE:5. SPEED=100mph=160.9kmph and duration=20seconds. All other parameters are set as default.
In the below table, it is seen that the gradeability has been tested for different speed values keeping the duration values constant. from the table, it is evident that the gradeability decreases with the increase in speed of the vehicle. the change in duration has no the gradeability of the vehicle
