Week-11 Challenge: Braking

THEORY : An Electric Vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery, solar panels, fuel cells or an electric generator to convert…

#1. Search and list out the total weight of various types of aircrafts.  Weight is a major factor in airplane construction and operation, and it demands respect from all pilots and particular diligence by all maintenance personnel. Excessive weight reduces the efficiency of an aircraft and the available safety margin if…

AIM: For a defined driving cycle, calculate the energy required for braking. To define why electric motor can’t develop braking torque at high speed similar to starting and how electric and mechanical brakes are coordinated. To make a MATLAB program which plots contour of given motor speed, torque and efficiency…

DC-DC Converter DC-DC converter is an electronic circuit that converts DC voltage from one voltage level to another. It can be step up or step down of voltage. This type of converter is also known as chopper. The electric components inside the vehicle vary in their voltage requirements, with most running on much lower…

1.A. Speed control of a DC motor using BJT H-bridgeHere H-bridge  DC chopper circuit is designed to control the speed of the motor.IGBT acts as BJT in power switching devices.Four IGBT switches are used for inverting the DC voltage 0 to 240 v supply.The current flows from collector(C) to emitter(E).The gate are controlled…

1. a) AC to DC converter which is called "Rectifier" - It converts AC into Unipolar DC current. b) DC to AC converter which is called "Inverter" - It converts DC into AC of desired voltage and frequency. c) DC to DC converter which is called "Chopper" - It converts…

1.mapped Mapped models are used when the behavior of a particular model is not of our interest and can be modeled with predefined values in the form of lookup tables. Implements a mapped motor and drive electronics operating in torque control mode. we have to specify electrical torque range with a torque-speed envelope…

1. use the advisor tool to applied given values kerb weight and km 2. repeat the simulation but changed battery capacity some similar changes 3. this timeapplied the gradebility test to run    cocnclution    three models result are similar changes output are different values
