2. 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..

 Charging circuit
 Dynamo motor
 Starting motor
 Battery bank
 Gearbox

6. 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

7.  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

8. Scrap body 8

9.  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

11. 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

12.  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

13. 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.

14. 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

16. Driving through a propeller
shaft
Front engine rear drive

17.  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

18. STARTING MOTOR
18

19.  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

20.  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

21. TYPES OF CHARGING
 Mainly three types of charging is provided in the
set up
 Plug in charging
 Solar charging
 Regenerative charging
21

22.  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

23. Charging circuit 23

24.  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

25.  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

26. 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 kmhr
26

27. 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

28.  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

29. 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

30. 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

31. Result and Conclusion
 An eco- friendly and economical electrical
car is designed and practically developed
using scarp materials.
