Week-6 Challenge: EV Drivetrain

A vehicle direction determination model is created using MATLAB Simulink as per the requirements given. Firstly a blank model is created to which a data dictionary is linked. This SLDD file is defined using the given parameters as shown in the figure below. Based on the conditions given, all inputs are set to ImportedExtern,…

1. Battery Harness Dashboard the battery closed loop harness model is as shown. This dashboard consists of a BMS_state request subsystem which selects the variant based on the signal given from the test sequence variant. This request  is ent to the BMS_ closed loop model to get BMS_input, BMS_output and BMS_info.…

1. Table of materials and chemical reactions Types Chemical Name Cathode Material Chemical Reaction at Cathode Anode Material Chemical Reaction at Anode Overall Reaction Lithium Cobalt Oxide(LCO) LiCoO2 Lithium Cobalt Oxide CoO2 + Li+ + e- <-> LiCoO2 Graphite carbon  LiC6 <-> C6 + Li+ e-  LiCoO2 +…

The electric vehicle overall block diagram can be as shown in the figure. An electric vehicle consists of three subsystems: Electric propulsion subsystem, energy source subsystem, and auxiliary subsystem. An electric subsystem receives the command from the driver as per the input, which goes to the electronic converter…

6A. The total tractive force acting on the towing vehicle depends on many forces such as  rolling resistance force aerodynamic drag force hill-climbing force For a towing vehicle moving at a very slow speed, the aerodynamic drag force is minimum as this force is directly proportional to the velocity of the vehicle.…

1. Energy Required for braking. The defined drive cycle taken for consideration is WLTP3 - World Harmonised Light Vehicles Test Procedure - Class 3. The excel sheet is attached with this document. The plot of WLTP3 Drive cycle is given below Calculating the braking energy for Mass M = 500kg , Vf - final velocity after…

1A. Speed Control of DC Motor using BJT - H bridge: The mathematical model is given by Speed Control of DC motor using BJT - H bridge has a two-quadrant operation. It consists of 4 Power electronic switches Q1 Q2 Q3 Q4. Each leg has two switches and there are two such legs. Only one switch should be turned ON in one leg…

1. The types of power converter circuits that are employed in electric and hybrid electric vehicle are : DC-DC Converters: Isolated, Non-Isolated, Resonant Converters. DC-AC Converters: Inverter AC-DC Converters: Rectifier AC - AC Converters 2. Electric Motor Power Train  Vo = 70% (Va) = 70%(72) = 50.4 V Ra = 0.5…

1. The ev_default.in model is loaded and the cargo weight is set to 500kg which makes the total weight to 1508kg.   Now Clicking on next the simulation parameters appears. Here, set the drive cycle to CYC_FTP, No of Cycles is 1.   Then click on RUN.   It can be seen from the plot that for 1 FTP cycle the…

1. Mapped Model: Here, the model uses a predefined set of values such as a look table to characterize the performance. This table provided the overall characteristics with respect to engine, motor, or generator. This is also known as a static model and it takes less time to simulate as it does not involve real-time outputs…

 AIM:  To analyze and carry out a system-level Simulation of an All-Terrain-Vehicle using the Simulink model.  INTRODUCTION: An all-terrain vehicle (ATV) as shown in Fig1 is also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American…

Implementation of washing machine process using MATLAB Stateflow. A washing machine is an appliance that is used for washing clothes on a day-to-day basis. The washing machine begins when a proper power supply and water supply are given. The conditions given for working of the washing machine is stated in table 1 Sl No…

1. Simulink model of doorbell using a solenoid block. In this problem statement, a solenoid has to be connected in series with a switch that is connected to a supply. The switch closes every 2 secs and opens after 2 secs. When the switch closes for 2 secs the solenoid is energized and pulls the plunger of the bell to create…
