Week-3 Challenge: ADVISOR Tool

Ans1:

Objective: 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 or not which we are going to unravel with the help of ADVISOR TOOL an additional extension of Matlab.

• Step 1: Install Advisor tool add path of the folders and subfolders to matlab.
• Step 2: Write advisor in command window and wait.
• Step 3: Select Metric and select start.
• Step 4: Select EV_defaults_in from drivetrain config.
• Step5 : Press Continue with all default parameters.
• Step 6: Change drive cycle type from CYC_UDDS to CYC_FTP.
• Step 7: Hit run.
• Step 8: It can be observed that from one drive cycle 17.8 Km distance is covered.
• Step9: Hit back and change no of cycle to 3 and hit run.
• Step 10: It can be observed that from three drive cycle 48.2 Km distance is covered till SOC reached zero.
• Step 11: Hit back two.
• Step 12: Change cargo mass to 500Kg as asked and hit continue.
• Step 13: Change no of cycle to 1 and run.
• Step 14: It can be observed that from one drive cycle 17.8 Km distance is covered. ( which is same for default cargo mass which is 136Kg)
• Step 15: Hit back.
• Step 16: Change no of cycle to three and run.
• Step 17: It can be observed that from three drive cycle 41.4 Km distance is covered till SOC reached zero.

Therefore it is observed than for default condition the vehicle can run 48.2 Km but for increased cargo mass which is 500Kg the vehicle can cover only 41.4Km to zero SOC of Battery nad cannot go further. Thus it cannot travel 45Km.

Ans2:

Objective: From the above case, try changing the battery capacity and repeat the simulation. We will try increasing battery votage till the vehicle reaches min 45 km distance.

• Step1: Load EV_defaults_in file and change cargo mass value to 500Kg from 136Kg and hit continue.
• Step2: Again repeat step6 from above.
• Step3: Now run simulation for three duty cycle.
• Step4: It is observed that with defalt battery bank voltage (25 no of battery, total 308VDC ) the vehicle travel 41.4 Km.
• Step5: Now after changing several times it is observed that if 3 no of battery module is added to bank (28 no of battery , total 345VDC) and after simulating with 3 duty cycle the vehicle can reach 46.3 km till soc(state of charge) turned to zero.

Please watch below mentioned video(made by myself) to gain better understanding for Above mentioned both operation was done and explained.

Ans3:

Objective: To perform gradeability test with PRIUS_Jpn_defaults_in file , Compare your results in table and conclude.

• step1: Open Advisor tool.
• Step2: Load PRIUS_Jpn_defaults_in.
• Step3: Run with 1 drive cycles of CYC_UDDS.
• Step4: Let us assume several different vehicle speed condition as 15Mph , 35Mph, 55Mph, 75Mph , 95Mph.
• Step5: Check gradability test and from option simulate each speed condition mentioned above.
• Step6: From report data we can examine Gradeability %

Please watch the video linked below for better understanding.

Speed vs Gradeability table.

CONDITIONS	SPEED (kmph)	GRADEABILITY (%)
CONDITION 1	24.1	24.4
CONDITION 2	56.3	13
CONDITION 3	88.5	8.9
CONDITION 4	120.7	5.3
CONDITION 5	152.9	2

It is cuncluded that speed is inverse proportional to Gradeability of vehicle.
