Week-3 Challenge: ADVISOR Tool
Aim:
For the EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with an 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
for this
I am downloading the ADVISOR model from the given link
MATLAB path is set to the ADVISOR model path
by giving the command 'advisor' ADVISOR model starts
A starting GUI appears in which we can start new models or only truck models or else we can load the previously done models
after pressing the start button
another GUI appears in which we can load different types of models of cars
Question 1:
load the EV_defaults_in file as shown in the figure
if we can observe this is a fully electric vehicle
with
25kW of energy storage
a motor with 75kW maximum output power
cargo is changed to 500 kgs
which results in the total mass of the vehicle 1508kgs
which includes weight of motor, energy storage, wheels, etc
we can also observe the motor efficiency plot in which motor Torque vs Motor Speed characteristics are shown on the left bottom side of the GUI
now we press continue
another GUI where we can select the drive cycle
which is cyc_ftp drive cycle which is asked in the question
we can observe the different parameters that has shown
total time 2477s
total distance covered 17.77km
naximum speed 91.25kmph
avg speed 25.82kmph
by this we can observe that the selected model EV_Defaults_in for drive cycle CYC_FTP can not reach the distance of 45 km
we can set other parametrs like acceleration test
gradeability test
parametric study of any 3 from the list at a time
we can define electric Auxilary loads
after setting all this up if we click run
the actual simulation runs
and the results GUI appears as shown below
here we can observe that right side of the GUI shows the parametrs that we want to know.
Question2:
the above model is modified in which the battery capacity is changed
I changed the battery capacity from 25kW to 35 kW
we can observe the total mass of the vehicle increased
now click continue
there is no change in distance covered and max and avg speeds
the results GUI is
the increase in battery capacity will increase the mass of the vehicle which results in an increase in various forces
we are not considering the acceleration and gradeability test
if they might be a decrement in them
the results GUI is
Conclusion: The Advisor model will calculate every instantaneous parameter according to the input that we have given.
Question3:
Aim: To Perform gradeability test with PRIUS_Jpn_defaults_in file
let us press back where the load file GUI appears
lets load PRIUS_Jpn_default_in file
we can clearly observe that the Prius that we are operating is a japan model
Prius japan is a hybrid vehicle in which motor and ice are employed in opposite directions, a generator is employed side of the motor to generate a voltage
the specifications are
energy storage 40kW
motor output power 31kW
Generator output power 15kW
fuel converter 43kW
these three machines are coupled with a mechanism called ccp common coupling point.
we can observe the different characteristics are plotted
we can choose from the options that
fuel converter
motor controller
generator
energy storage
and their sub characteristics
let us select the drive cycle and gradeability test for this model
the drive cycle is chosen to be set default which is CYC_UDDS
in this drive cycle, the distance covered by the car is 11.99kmph
the maximum speed of the car is 91.25kmph
The average speed during the cycle is 31.51kmph
Let's set the Gradeability test where
all points are set by default as this is real car data we can set the grade and also its boundaries but now I chose to go for default one
now let's run the simulation
finally the results GUI is
we can observe the right side of the GUI
gradeability test results are shown which is
like this, we can conduct acceleration tests also
Conclusion: The ADVISOR model is a very useful tool for modelers and engineers in which we can test the model with different parameters and different drive cycles, many tests like Acceleration tests, Gradeability tests, and particular parametric studies are done using its GUI.
