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.

Answer:

Enter the "Advisor" in the MatLab command window to open the Advisor tool.
Then select the " EV_defaults_in" from the load file tab as shown below.
Change the cargo mass to 500 kg with all other default condition.

Press continue to move to the next step.
Select the Drive cycle tab and choose "CYC_FTP"
The bar graph in the below image reprents that around 42% of the time the vehicle is at 0 kmph.
The distance of the one cycle is 17.77 km & time is 2477 sec.
Lets run the mode for one cycle.

After simulation the results are as follows.

Observed that SOC of storage device is around 60% after 17.8 km.
Lets increase the Cycle to 3 and observe the result.

Observed that at 42.4 km the SOC of the storage device is 0%.
So it is not possible for a vehicle travel for 45 km with FTP drive cycle at default value.

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

Answer:

By changing the Energy storage to the "ESS_PB65_FocusEV", now 28 modules are available & Voltage is 353v. Also weight increased to 1779 kg.
Lets run the module with "CYC_FTP" drive cycle for 3 cycles.

Run the simulation.

After 3 cycles the vehicle traveled 53.3 km & the SOC is around 50%.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Answer:

(a). After loading the PRIUS_Jpn_defaults_in file , keep all values to the default. Choose the gradeability test in the next window. For the speed at 60 mph & 10 sec duration calculated gradeability when energy storage is disabled.
