Week-3 Challenge: ADVISOR Tool

Week 3 Challenge:

Advisor Tool:

ADVISOR was first developed in November 1994. Its main purpose was to help manage the U.S. Department of Energy’s (DOE) hybrid electric vehicle (HEV) program subcontracts by facilitating our understanding of the technical challenges inherent in the design of highefficiency HEVs. ADVISOR uses drivetrain component performance to estimate fuel economy and emissions on given cycles as well as maximum-effort acceleration capability. It is fundamentally an empirical model.

Aim:

• 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.

• In the above case, try changing the battery capacity and repeat the simulation.

• Perform gradeability test with PRIUS_Jpn_defaults_in file.Compare your results in table and conclude.

Q1. 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 using matlab m.script file. Then change the load file EV_default_in . then change the cargo mass to 500 kg . then below right side have continue button then click on continue. In this GUI left side have vehicle contour plot.

After click on continue, 'simulation parameter advisor tool' was opened in matlab window. Then change the drive cycle parameter CYC_UDDC to CYC_FTP. Keeping all the default parameter are same then click on run button .

After clicking run button result interface is open in matlab window .

Above result plot we can see that left side have distance plot in mile per hours(mph). then energy storage system(ess)-state of charge (soc) plot , after 2500 sec(aprox. 41 min) soc was zero , soc zero means battery is discharge condition. . Then emissions and overall retio plot also here. In this condition vehicle travelled only 11 miles(aprox 17.8 km) , that means vehicle can’t travel 45 km in a single charge.

Q2. In the above case, try changing the battery capacity and repeat the simulation.

According to question required I was changed vehicle energy storage to ESS_PB25_IDEAL. Then click on continue.

Keeping drive cycle and all the date are same then click on run button.

From the result here we see that vehicle covered only 17.8 km in single charge. Ess-soc discharge after 2500 sec. so after changing the energy storage all over result are same.

To get how much distance are vehicle travel in single charge ,so we need to increase the no. of drive cycle 1 to 8 then will simulation the programme to 8 drive cycle.

After increasing the drive cycle then click on run button.

From the above result here we observed vehicle covered 28.7 miles (aprox 46.19 km) distance in single charge . after 6000 sec (100 min) ess-soc was zero. According to this above result so we say that vehicle travelled 46.19 km in single charge.

Q3. Perform gradeability test with PRIUS_Jpn_defaults_in file. Compare your results in table and conclude.

After opening advisor tool then click on load file drop down menu and select PRIUS_Jpn_default_in file. Rest of the parameter kept default condition.

Then click on continue button right bottom corner of the window.

Then click on gradeability check box. The vehicle speed kept same as a 55 mph. then click on ok. Then click on run button

This time gradeability of vehicle is 1.7% at 88.5 km/h speed.

Then change the vehicle speed and check the gradeabilty of vehicle. This time vehicle speed puted 50 mph and click on ok.

This time gradeability of vehicle is 2% at 80.5 km/h speed.

Then change the vehicle speed and check the gradeabilty of vehicle. This time vehicle speed decrease more , puted 30 mph and click on ok.

This time gradeability of vehicle is 2.5% at 48.3 km/h speed.

According to all the result I conclude that when vehicle speed is decreasing this time gradeability is increasing and when vehicle speed increasing gredeability is decreasing. So if the vehicle needs more gradeability then the vehicle should be driven slowly.

Conclusion:

• In first condition we observed vehicle can't be travelled 45 km/hr in FTP Drive cycle. because of when vehicle cargo weight increase to 500 kg vehicle travelled only 11 miles( aprox. 17.8 km) .
• In this condition we observed when vehicle drive cycle change 1 to 8 then vehicle travelled 28.7 miles( aprox 46.2 km).
• In this condition we was checked PRIUS_Jpn_default vehicle gradeability. we observed when vehicle speed is decreasing this time gradeability is increasing and when vehicle speed increasing gredeability is decreasing. So if the vehicle needs more gradeability then the vehicle should be driven slowly.
