Week-6 Challenge: EV Drivetrain

Main Project – Adaptive Cruise Control (ACC) General Overview: Adaptive Cruise Control Feature for passenger cars allows the host vehicle to adapt to the speed in line with the flow of traffic. Driving in heavy traffic or keeping a safe distance to the preceding vehicle calls for a high level of concentration. The…

AIM:  To create a Simulink model of Vehicle Direction Detection as per Requirement Data. Objective of Mini Project: Development of MATLAB Simulink model as per requirement. Tag the requirements to the simulink model; tagging requirement 1 & requirement 2 to their corresponding subsystems is fine. MBD compliant…

THEORY:  When temperatures increase this affects the chemical reactions that occur inside a battery. As the temperature of the battery increases the chemical reactions inside the battery also quicken. At higher temperatures one of the effects on lithium-ion batteries’ is greater performance and increased storage…

1.Simulate the 3 test cases from harness dashboard and write a detailed report on the results. This is the dashboard which represents the dashboard in the vehicle. It indicates the battery states - Balancing, Charging and Driving. There are LEDs to indicate any faults or errors and for other purposes. PROCEDURE: There…

1. Prepare a table which includes materials & chemical reactions occurring at the anode and cathode of LCO, LMO, NCA, NMC, LFP and LTO type of lithium ion cells.Give your detailed explanation on it   Lithium ion batteries can be designed for optimal capacity with the drawback of limited loading, slow charging…

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      …

PART A: 1. Search and list out the total weight of various types of aircrafts. 1. Aircraft Total Weight: The aircraft gross weight is also known as the All-up weight and abbreviated AUW is the total weight at any moment during the flight or ground operation. An aircraft's gross weight will decrease during a flight due…

1) For a defined driving cycle, calculate the energy required for braking. SOLUTION: CODE: close allclc %Read the Drive Cycle dataDC=xlsread('drive cycle.xlsx'); %Time and Speed in secondsT=DC(:,1);S=DC(:,2); %other datam=1000; %mass in KgV=S./3.6; %speed in m/s %Creating an array to store values for Deceleration and Braking…

Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. Comment on the armature current shoot-up from the scope results. Refer to the help section of ‘The Four-Quadrant Chopper DC Drive (DC7) block’. Compare it with the H-bridge model. Solution: A) Model: This example…

1.  Which types of power converter circuits are employed in electric and hybrid electric vehicle?    ANS: Rectifier:This circuit helps us in the conversion of alternating current (AC) to direct current (DC). This involves a device that only allows one-way flow of electric charge. In EVs, this is used…

AIM 1: What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Mapped vs Dynamic Engine Model   Mapped Dynamic Features Data is taken from a Look-up table. This data is then configured with the parameters of the Engine Here the results are obtained…

AIM 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. THEORY: Advanced Vehicle Simulator (ADVISOR) was first developed in November 1994 at the National Renewable Energy Laboratory. It…

AIM:  To prepare a detailed technical report on BAJA All-Terrain Vehicle (ATV) simulation under varying conditions. OBJECTIVES: Conduct a system level simulation under varying parameters and inputs and prepare a technical report as well as observe and study the various outputs. THEORY: All Terrain Vehicle (ATV):ATV's…

Simulink for Mechanical and Electrical Engineers - Challenge : Week 4 OBJECTIVE 1: Implement control logic of a “washing machine” using Stateflow as per given sequence:  If the power supply is available, the system gets activated  If the Water supply is not available, stop the process & indicate…
