Week-6 Challenge: EV Drivetrain

Power Converters inside Electric Vehicle:      There has been 3 Types of Power converts used since years inside an electric vehicle. 1) DC - DC Converter :     DC-DC converters are mainly classified as shown below..                Here, the Linear DC-DC converter uses sophisticated method of dissipating power across resistor…

  Create a MATLAB model of electric car which uses a battery and a DC motor. Choose suitable blocks from Powertrain block set. Prepare a report about your model including following: Objectives:         1. System level configurations        2. Model parameters        3. Results        4. Conclusion   Solution :     The…

Question 1              : What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?    Question 1 Solution :          The prime difference between mapped & dynamic model of the Motor, Generator or any other machine is that , the mapped model of any machine is…

Objective Of the Project :   Create a MATLAB model of electric car which uses lithium ion battery and suitable motor. Choose suitable blocks from Simscape or Powertrain block set. Implement the vehicle speed control using PI controller and generate brake and accelerator commands. Avoid using readymade driver block for…

Project Problem :     Using MATLAB/simulink and  the drive cycle from the attached excel sheet, find- The max heat generation of the battery  The SOC of the battery at 2 *104second of the battery operation Consider the battery resistance is 0.5 mOhm, delta time is 0.1 and entropic factor is 2  …

Question 1 Solution: The data given for the car specifications as,Power requirement (P) = 150 KW Operating Voltage (V) = 120 V Battery Specifications, Battery Capacity = 3500 mAh Nominal Voltage = 3.6 V Nominal NMC chemistry Battery. So First Rated current required by Car = 150 kW/120 = 1250 A Here, We will calculate first…

Part A Solution : 1) Answer 1: The aircraft itself is a big giagantic system you could say & it's having different parameters which affets it's weight.Let's go through some brief information regarding to Aircraft weight depending parameters. Every aircraft has a maximum weight that is provided by the manufacturer.…

Question 1 Solution: Calculation for acceleration & Decelearation both require define data to take as input for Mathematical computation.So I built my own pattern for driving cycle with Time vs. Speed data as per follow.   Barking power needed to decelerate the vehicle for each time period would be different. i.e. Lets…

Question 1 Solution : As per asked to analyze the Model of 'Speed control of a DC motor using BJT H-bridge.' I went to the MATLAB official Website & got the link for Model.By pasting the link in MATLAB offline trial version the simulink Model pop uped as below.   (A). About Model : This is the simulation of H…

Question 1 Solution : Power converter circuit : A power converter is an electrical circuit that changes the electric energy from one form into the desired form optimized for the specific load.As in our Electric Vehicle application Power required by it is time varying i.e. the amount of power needed to propell vehicle is…

Question 1 Solution : As asked in question for Load file( EV_defaults_in ) I have not changed the default paramters except the cargo weight. I have taken cargo weight of 500 kg.which can be seen in folling picture.   By setting this window , The Advisor jumped to the page of drive cycle setting & I have selected…

Explanation : The objective of the project is to make mathematical model of separately excited DC Motor & design the closed loop design with Proportional,Deriivative & Integral gains with speed control of motor.The Mathematical model is the main key to unlock the simulink design & parameter equations for the…
