Week-6 Challenge: EV Drivetrain

Question 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.…

Mini Project - Vehicle Direction Determination General Overview: Identifying the direction of the vehicle is one of the important & diverse features in Autonomous driving & Advanced Driver Assistance Features. This particular sub-feature of identifying the direction of vehicle is basically identifying the direction…

Aim: Create a MATLAB model of electric car which uses a battery and a DC motor. To check out performance parameters speed, SOC, current with FTP drive cycles. Theory: EV Theory All-electric cars (EVs), also known as battery electric vehicles, store the electrical energy that powers the motor in a battery pack. The vehicle's…

PWM CONTROLLED FAN LOAD USING DC MOTOR Aim: To model a fan type load in Simulink and to control its speed by using the PWM method Theory:   The use of pulse width modulation to control a small motor has the advantage in that the power loss in the switching transistor is small because the transistor is either fully…

Q1. Search and list out the total weight of various types of aircrafts.  Ans 1:  Total weight of various types of aircrafts: Manufacturer's empty weight(MEW): Manufacturer's empty weight is the weight of the aircraft "as built" and includes the weight of the structure, power plant, furnishings, installations,…

Ans 1: Some assumed values are taken for the purpose of graph With the above data and attached excel file there is a graph between time and speed(mph). The speed mph converted into mps for calculation purpose   Calculations were, Mass = 1000Kg (Assumed) 6 decelerations were made during this drive cycle, so 6…

Ans 1A: H- Bridge Circuit  A H-bridge Circuit is a simple four q Circuit, where the input is provided as Vbat. Here the motor is connected in the center of the circuit, which looks like the letter H. The direction of current flow is shown in the following dia. In positive half cycle switches Q1 and Q4 conducts…

Ans 1: The three type of power converter which used in electric and hybrid electric vehicle are  DC to DC converter AC to DC converter DC to AC converter DC to DC Converter : A DC to DC converter is a category of power converters and it is an electric circuit which converts a source of direct current (DC)…

Ans1: The difference between mapped and dynamic model of engine is that, the motor and generator in mapped model is where data point are pre define in lookup tables. whereas in dynamic model for components like permanent magnet motor, VSI, PMSM real-time inputs are given to Permanent Magnet motor to work accordingly The…

Ans1.  Given below are the steps which are observed  Open Matlab window and extract advisor.m file  Type advisor in command window and enter The advisor window/GUI will open. Select unit as metric & click on start The main window/GUI will be open, load file to EV_defaults_in Change cargo weight…

Ans1: First we have to create chart for "washing machine” using Stateflow as per given sequence Our first block is taken as a powerOn, so as per conditions if power supply is avilable i.e.constant>1 then signal pass through next block otherwise it'll not proceed. After that the second conditions we have to…

1.Simulation Model For Doorbell   Model Explanation : First we have use the following block for this model i.e.pulse genrator, switch, battery, solenoid, ideal translational motion sensor, mechanical reference, electrical reference and scope. The Pulse generator is used send pulse at regular interval. As…
