ELECTRIC CARA home project by mechanical
students-PHOENIX
INTRODUCTIONELECTRIC 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.
MARKET FINISHED PRODUCT
raw pics of electric car
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:
MECHANISM IMPLEMENTED
Controller
BLDC HUB Motor
Steering
Braking
CONTROLLER
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
BLDC HUB MOTOR
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.
STEERING 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
BRAKING 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
BRAKING 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.
PRACTICAL DEVELOPMENTThe 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.
PRACTICAL DEVELOPMENT 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
