Abstract

This project presents the simulation of a bas

vehicle motor-drive system that is used to i

power flow during both motoring and regenermodel can also be used to evaluate the elect

energy flow and efficiency for specific speed a

load conditions.

Introduction

Electric vehicles are by many seen as the cars of the fu

The 20102020 time period described as the upcopointthe transition from the ICE to electric propulsio

The design process in industry has significant chanyears.

Model-Based Design is now commonly used in

aeronautical, and other industries.

Electric Vehicle Drive Train

The Vehicle Interface communicates with the Battery

and Motor Controllers.

A battery controller monitors and controls the battery

pack.

Motor Controller is used to optimize the performance of

the motor throughout the four quadrant modes.

Continued.

Battery provides required power to the drive.

power electronics unit converts the DC voltage

into desired form.

Motor will provide the required speed and torque

to the vehicle for propulsion purpose.

Powered by anElectric Motor

Battery stores electrical energy that powers the motor

Battery charged by plugging into outside electric

power source

Zero tailpipe emissions, but air pollution may be

produced through electricity generation

So, No local air pollution

Model based design/Simulati

The design process in industry has experienced signichange in recent years.(Model-Based Design)

Model-Based Design uses models in the process to cexecutable specifications.

Engineers can decrease both design costs and designenabling companies to complete and test designed ite

Comparison of conventional and M

process

Conventional design process

conventional design workflow

involves:

a) Requirements

b) Design

c) Implementation

d) Test and validation.

Model based design

Model-Based Design uses

the process to create exec

specifications.

Engineers then share moddemonstrate the performan

subsystems.


11/18

Comparison continue

Conventional design process Problems :

1) specifications must be understood

by different engineers.

2) application engineers have to

rewrite design engineers algorithms.

3) the problem is not found until the

testing phase.

Model based design Problems can be rectified

process itself.

Model Development Proce

It consists of 1) determining how the model will be used

2) identifying the key equations, parameters and

3) building and refining the model

4) the actual model application and evaluation.

The major components of the model are input road torque, i

speed, motor model, motor controller model, battery model,

controller.

Conclusion:

The world of electric vehicle development is changing fast. During 2011-2012 electric vehicles were mass produced for

in history.

Current engineering students will play key roles in the devel

the electricvehicles.

Simulation is a very real and necessary part of electric vehicdevelopment.

It vanishes the cost of on-road analysis and testing of a pa

design which is under development.
