Week-4 Challenge WOT Condition Part-2

1.What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?

Mapped Model	Dynamic Model
In this Model the data points are pre defined in lookup table	In this model the data is the combination of output of the various subsystem
The Accuracy of the model is less that is one of the drawback and the time taken for Simulation is less	The simulation time is very long compare to mapped model and the Accuracy of this model is very high its take output form all the subsystem
The engine or motor blocks generates the requiered torque output as required sumply without considering the real time engine or motor parameters	The Engine and motor block take input form real time simulation

2.How does the model calculate miles per gallon? Which factors are considered to model fuel flow?

• The above image Shows the subsystem of perfomance calculation
• In IC Engine we can calculate the fule economy by how much distance covered by vehicle and how much petrol or diesel used by the vehicle
• In EV also same but instend of petrol or diesel here we are using energy

• The input form vehicle speed is converted into miles by multiplying 0.000621371
• Fuel flow taken in mA3 and it is converted into equivalent Gallons by multiplying by 264.172
• For getting miles/gallon divid the inputs miles and gallon

3.Run the HEV ReferenceApplication with WOT drive cycle. Change the grade and wind velocity in the environment block. Comment on the results.

• Hybrid Vehicle means that vehicle using more than one power source for running the vehicle
• The above picture show that the hybrid electric vehicle Configeretion
• And this is a series Hybrid electric vehicle

• change the Drive cycle source to the wide open throttle
• The Above image Shows the Drive Cycle Source

• Now We Are Changing the input environment of the system

• The Above Image shows the plot Diagram of trace Velocit,Target, actual(mph)

• The Plot Diagram Shows the Battery Current Usage

• This plot digram shows the engie speed and Motor Speed ,and generator speed in RPM

• This plot shows the Sate of charge of the battery

• this plot shows the Enginne, motor, ang generator Torque

• This Plot Shows the Us fule economy in Mile per galon energy

4.Keeping all other parameters same, compare the simulated results of hybrid and pure electric powertrains.

• The above Diagram Shows the model of Pure Electric Vehicle
• Now We arw going to change the parameter of drive cycyle same to the HEV
• then we will see the difference between the HEV and Pure EV

The Below Plot Graph Is

• trace Velocit,Target, actual(mph)
• Battery Current Usage
• engie speed and Motor Speed ,and generator speed
• Sate of charge of the batter
• Enginne, motor, ang generator Torque
• fule economy in Mile per galon energy
