Week-3 Challenge: ADVISOR Tool

Objective – To check the objective in ADVISOR tool in matlab

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.
2. In the above case, try changing the battery capacity and repeat the simulation.
3. Perform gradeability test with PRIUS_Jpn_defaults_in file. Compare your results in table and conclude. 

Solution-  ADVISOR is a MATLAB/Simulink based simulation program for rapid analysis of the performance and fuel economy of light and heavy-duty vehicles with conventional (gasoline/diesel), hybrid-electric, full-electric, and fuel cell powertrains. ADVISOR stands for ADvanced VehIcle SimulatOR

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.

So first we open the Advisor tool in matlab start the Advisor tool.

We see the GUI for the tool at the top we can select the type of car in drivetrain configuration. Its type such as Parallel/ Series ot It can be a pure electric or Hybrid or a fuel cell type can be selected.

The weight of the car its efficiency of Engine or Electric motor and the Power output of motor is seen when the car model is selected.

In this case we select the EV_defaults_in model. We keep all the setting to default conditions and change the cargo to 500 Kg

Now we select on continue option to go to next GUI.

Here we see the options for selecting the type of drive cycle. Number of drive cycles. Grade ability test and acceleration test. We select the FTP cycle,  in the details we see time of cycle the distance covered and average speed etc.

Total distance is 17.77 km so we carry out 3 number of cycles for the car to cover the distance of 45 Km in FTP cycle.

We run the simulation. In the results we see that the range of EV is exceeded and total distance covered is 41.4 Km

So the EV_defaults_in model cannot cover a distance of 45 km for FTP cycle.

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

To increase the range of EV we change the battery capacity to ESS_PB65_focus EV which has 28 modules and 353 V.

And keeping the conditions same as the previous case we run the simulation.

We see that the car has travelled a total distance of 53.3 km in  3 FTP cycles. Thus by increasing the battery capacity we can increase the range.

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

First we select the drive train configuration to Toyota PRIUS model. Now keeping all the setting to default condition we continue to next GUI. 

In the Grade ability test we see the grade options. The grade test options are selecting as given below.

Case 1

Case 2

Case 3

Speed varies with the grade percentage to be 11%.

      Sr no                    Speed (Km/hr)                    Grade ability

         1                             64.4                                   11.7

         2                             72.4                                   10.7

         3                             80.5                                    9.7

         4                             88.5                                    8.9

Conclusion

The EV_defaults_in model cannot cover a distance of 45 km for FTP cycle.

After increasing the battery capacity we can increase the range. And the model can cover distance of 53.3 Km

Grade ability for Toyota Prius is carried out.
