INTRODUCTION

Global warming (climate change) is probably the most important issue to face our generation

There are many things we can reduce, and in many ways we can reduce them, the major ones are: reduce the amount of fuel we use

These concept will leads the development of the electric cars which is economical and pollution free..

PRACTICAL WORK  Having an electric car can save money on

gasoline and can be good for the environment

Choose a car for the electric car conversion

It is best to choose a traditional car to use for the conversion

Look for something lightweight since they will run better on an electric battery than a bigger vehicle will 6

A car with a manual transmission is better for an electric car since cars with electric motors do not necessarily need a transmission

The car that choose should also have enough room for an electric battery; it will need enough voltage to power the engine to choose

Weight distribution is very important for handling on the road

Scrap body 8

Select a motor for the car that can assemble

A DC motor with diminutive body is the standard motor for an electric car conversion

Here we are used dynamo motor with a gear system that will explained below

This is the transformation kit that used for the system

DYNAMO MOTOR

A dynamo is an electrical generator that produces direct current with the use of a commutator

A dynamo machine consists of a stationary structure, called the stator

Dynamo motor is the main componet that drive the vechicle

11

Dynamo motor ratings are 12 V,24 A That is used in it

Dynamo motor uses the commutator for needed to produce direct current

Main applications of the dynamo motors are Electric power generation, Transport and other modern purposes

 12

SPEED CONTROL IN ELECTRIC CAR

Speed control can be used by three methods:

• Gear system• On Load tap changing on transformer• Varying stator resistance In this project we using gear system method.

13

Gears and Transmission Overview

It has 4 speed manual transmission gearboxes for all available vehicles . Here we used Maruti Omni gear box

Detailed description of the gear box is shown in the below figure

Driving through a propeller shaft

Front engine rear drive16

In rear wheel drive system the transmission is done through the clutches, gearbox and propeller shaft

allow for the constant movement, spines on the front end of the propeller shaft slide in and out of the gearbox as the distance changes

17

STARTING MOTOR

18

Starting motors are mainly used for providing the starting torque

In this we are provided starting motor with the rating of 12V and 1KW

Starting motor is powered by a separate battery pack

19

Selection of battery

There are mainly two types of battery packs are used, one for the dynamo motor and other for the starting purpose other electrical needs

Battery rating is 12V,90Ah

It takes 8hrs for full charging

20

TYPES OF CHARGING Mainly three types of charging is provided in the

set up

Plug in charging

Solar charging

Regenerative charging

21

Plug in charging

In this charging the main components are

14V,8A Transformer, Full wave rectifier

A LED is provided for the charging indication

22

Charging circuit 23

Solar charging

Solar charging is done through solar panels

Here two 12v solar panels are used and aggregate 24v is get from these panels

The charge that get from the panels are dc voltage, because of this there is no need of inverter

24

Regenerative charging

It’s a mechanism in which the series motor acts as a generator

By this action the motor generates power

utilizing this power through charging the batteries

25

CHARACTERISTICS OF THE E-CAR

Time taken for the full charging of battery is about 8 hrs

E-car gets millage up to the range between 10 to 15 km

Maximum speed range of the car is fed between 30 to 40 km\hr

26

TYPES OF PROPOSED CONVERTING KIT

3 PHASE AC TYPE

In this 3 phase squirrel cage induction motor is the main component that drive the vehicle

It gets millage up to 100km on full charge and speed is around 70 to 80 kmph

27

DIRECT CURRENT TYPE

In this forklift dc series motor is used as the main component

It gets around 80 km mileage on full charge and speed up to 50 to 60 kmph

28

ADVANTAGES

It is a coherent system that can be installed for all kind of vehicles

Economical and eco friendly Availability of electric energy is very

high Easy recharging at home or at work Less pollution compared to engine

vehicles

29

DISADVANTAGES

Batteries need to be charged. Car can not be used when batteries are

being charged. Car can only run 15km between charges Battery disposal needs to be carefully

managed

30

Result and Conclusion

An eco- friendly and economical

electrical car is designed and practically

developed using scarp materials.
