Week-3 Challenge: ADVISOR Tool

1)

Simulation of EV_default  using ADVISOR tool is shown below

Case 1) For default cargo mass of 136 kg

With default battery value of ESS_PB25 ,

First of all select the required model from drop down list of LOAD FILE

Then press the continue button of the window

• After that select the needed drive cycle from the DRIVE CYCLE drop down menu

Using the drive cycle of FTP for 5 cycles

Then according to the requirement select the no of cycle

• After that select the RUN button to start the simulation

Following result is obtained

• If a particular parameter variation is to be plotted , then ,from the component menu select the component for display then using the plot variable menu select the parameter needed to be plotted

So we can see 

  1) the distance travelled is 48.2 km before the battery is depleted to 0 value.

   2) Gasoline equivalent valueis 2.1

Case 2) cargo mass of 500 kg

From the drop down menu of cargo mass as higlighted , enter the required weight

Keeping all the parameters same 

with FTP DRIVE cycle for 5 times

the output obtained is

As its visible that after increase in the cargo weight the distance travelled by the vehicle has reduced to 41.4 km and the power consumption has increased to gasoline equivalent of 2.5 value.

So after increasing the cargo weight to 500 kg vehicle cannot travel 45 km before getting depleted of charge.

2)

For this part we will be changing the cargo weight as well as the battery capacity and observe the change

CASE 1) CARGO WEIGHT OF 136 Kg

CASE 1A) Using the default battery of ESS_PB25 

USING THE FTP DRIVE CYCLE FOR 5 REPEATITIONS FOR ALL CASES

the results obtained is

It can be deduced that at 0 charge point the distance travelled is 48 km and the battery module temperature rises to an approx value of 28-29 degree celcius.

CASE 1B) Using the  battery of ESS_PB18 -  

 From the drop down menu of Energy Storage as higlighted , select the required battery variant

WITH change in battery capacity the mass of vehicle has also changed. After simulation the result is

It can be deduced that with change in battery capacity the distance travelled before getting depleted has been reduced in comparison to the PB25 battery.

CASE 1C) Using the  battery of ESS_PB65 -

Keeping drive cycle same , the result of simulation is

It can be deduced that with change in battery capacity the distance travelled before getting depleted has been increased in comparison to the PB25 battery.

Case 2) Cargo weight of 500 kg

CASE 1A) Using the default battery of ESS_PB25 

Result of simulation 

CASE 2B) Using the battery of ESS_PB18 -  

THE RESULT OBTAINED IS 

CASE 2C) Using the  battery of ESS_PB65 -

RESULT OBTAINED IS

SO FOR THE ABOVE SIMULATION THE CONSOLIDATED INFERENCE THAT CAN BE OBTAINED IS AS FOLLOWS

With increase in load the total distance travelled decreases.

3)

GRADEABILITY TEST WITH PRIUS_JPN_DEFAULTS_IN FILE

For performing this simulation first of the prius model is selected

After selecting the model then the parameters are set

 

Drive cycle selected is UDDS with 1 cycle of test

• Then we enable the gradibilty test by ticking the gradebility dialogue box.
• Then by selecting the grade option we get the window for changing the values

 

Grade value is kept at 6 and velocity values are changed

1) velocity = 1 mph or 1.6kmph

 

2) velocity =  5 mph or 8 kmph

3) velocity = 10 mph or 16.1kmph

 

4) Velocity =  18 mph or 29 kmph

4) velocity = 25 mph or 40.2 kmph

 

5)  Velocity =  28 mph or 45.1 kmph

6)velocity = 35 mph or 56.3 kmph

 

7)  Velocity = 40 mph or 64.4 kmph

8) velocity = 50 mph or 80.5kmph

 

It can be deduced that keeping the grade constant and varying the velocity the gradebility changes.

GRADE	VELOCITY(mph)	VELOCITY(kmph)	GRADEABILITY
6	1	1.6	31.7
6	5	8	32.8
6	10	16.1	30.3
6	18	29	21.5
6	25	40.2	16.5
6	28	45.1	15.3
6	35	56.3	13
6	40	64.4	11.7
6	50	80.5	9.7

From the graph we can deduce that with grade as constant and velocity on the rise , the gradibilty decreases.
