The document outlines a student project to build an electric car. It will be constructed in 4 stages over 3 months. Stage 1 will modify an existing electric car chassis. Stage 2 will add the steering mechanism. Stage 3 installs the motor, batteries, and controller. Stage 4 fits brakes, lights, and other accessories. The car will use a 48V 500W hub motor, drum brakes, and lithium-ion batteries. It is estimated to cost 150,000 INR to complete.

2. ELECTRIC CAR
 An electric car is an automobile that is
propelled by one electric motor or more,
using electrical energy stored in the
batteries or another storage device. Electric
motors give electric cars instant torque,
creating strong and smooth acceleration.
 The German Flocken Elektrowagen, built in
1888, was the world’s first electric car.
Electric cars were also popular in the late
19th century and early 20th century.

5. Benefits of electric cars over internal
combustion engines automobiles include a
significant reduction of local air pollution, as
they do not emit tailpipe pollutants, in many
cases, a large reduction in total greenhouse
gas and other emissions.
Less dependency on foreign oil, which in
several countries is cause for concern for
vulnerability to oil price volatility and supply
disruption.
Electric vehicles show significant reductions in
overall well-wheel global carbon emissions due
to highly carbon intensive production in
mining, pumping, refining and the efficiencies
obtained with gasoline.
BENEFITS:

6. Controller
BLDC HUB Motor
Steering
Braking

7.  The electric vehicle controller is the
electronic package that operates between
the batteries and the motors to control the
vehicle’s speed and acceleration.
 The controller transform dc from the battery
current into ac and regulates the energy flow
from the battery.
 The controller will also reverse the motor
rotation and convert the motor into a
generator

8.  Brushless DC motor are more synchronous
motors that are powered by a DC electric
source via power supply which produces an
AC electric signal to drive the motor.
 It produces higher efficiency and a lower
susceptibility to mechanical wear.
 It has several advantages including more
torque per weight, more torque per watt,
reduced noise, increased reliability and
longer lifetime.

9.  Steering is the term applied to the collection
of components, linkages etc. which will allow
a car to follow the desired course.
steering mechanism: 1 Steering wheel; 2
Steering column; 3 Rack and pinion; 4 Tie
rod; 5 Kingpin

10.  Four drum brakes(two rear and two front) are
the brakes planned to assemble in the electric
car.
 Rear brakes are to be engaged using foot
brake system
 Front brakes are also to be engaged using foot
brake

11. A drum brake is a brake that uses friction
caused by a set of shoes or pads that press
against a rotating drum-shaped part.

12. The project is planned to complete in 4 stages
 STAGE 1
Chassis of our electric car will be the modified
chassis of electric car brought in working
condition.
 STAGE 2
Then the steering mechanism along with axle
and wheel setup will be installed.

13.  STAGE 3
After this, motor, battery, controller will be
assembled to function properly
 STAGE 4
At the end brakes, light, seat and other
accessories will help to accomplish our
electric car
