This document summarizes a final year project on a regenerative braking system. The project is carried out by four students and guided by Shushant Sir. It discusses the basic concept and working of regenerative braking systems, the components used including motors and wheels, and the advantages such as reduced fuel consumption and emissions. Potential applications are in electric vehicles, elevators, and manufacturing conveyor systems. The document also outlines the future scope and a projected cost of 4800 rupees for the system.

2.  Regenerative braking is an energy recovery mechanism
which slows a vehicle or object by converting its kinetic
energy into a form which can be either used immediately
or stored until needed.
 Brakes are employed to stop or retard the motion of any
moving body.
 The basic concept of regenerative (“regent”) brakes,
which provide braking for the system when needed by
converting the available energy to some usable form.
Introduction

3.  It works of the principle of law of conservation of energy.

7.  Energy Conservation.
 Wear Reduction of brake.
 Less fuel Consumption.
 Braking is not total loss.
 Increase overall energy efficiency.
 Emission Reduction.
 Reduce pollution relevant problems.
Advantages of RBS

8.  For recovering Kinetic energy of vehicle lost during braking
process.
 In a manufacturing plant that moves material from one
workstation to another on a conveyor system that stops at
each point.
 Regenerative braking can be used in elevator and crane hoist
motors.
 Regenerative Braking Systems can be effectively used in
electric vehicle.
 Can be used in high speed cars(racing cars), as they have
more Braking energy to recover
Applications of RBS

9.  As regenerative braking save up to 30% of energy new inventions can be
discovered in the form of new electric motors through which more energy
can be saved and installed in many vehicles which can helpful in avoidance
of transmission losses, increase the efficiency and helpful in for
conservation of energy for greener future.
 Regenerative braking systems require further research to develop a better
system that captures more energy and stops faster.
 As the time passes, designers and engineers will perfect regenerative
braking systems, so these systems will become more and more common.
 All vehicles in motion can benefit from these systems by recapturing
energy that would have been lost during braking process.
 Future technologies in regenerative brakes will include new types of motors
which will be more efficient as generators, new drive train designs which
will be built with regenerative braking in mind, and electric systems which
will be less prone to energy losses.
FUTURE SCOPE

10.  Motor : 900rs
 Brake drum :. 1500rs
 Friction lining : 700rs
 Linking mechanism: 700rs
 Support system: 1000rs
 Total cost :. 4800rs

11. The system is proposed to salvage 50% of energy lost in braking. regenerative
braking is one of the important systems in electric vehicle because it has the ability
to save the waste energy up to 8-5%. the regenerative braking system has been
improved by the advanced power electronic component such as ultra capacitor, dc-
dc converter (buck-boost) and flywheel. the ultra capacitor that helps in improving
the transient state of the car during starting, provide a smoother charging
characteristic for the battery and boost up the overall performance of the electric
vehicle system. the buck-boost converter helps maintaining the power management
in the regenerative braking system such as boosting the acceleration. finally, the
flywheel is used to enhance the power recovery process through the wheel of the
car.in conclusion, the regenerative braking is a tremendous concept that has been
developed by engineers. in the near future, regenerative braking techniques can be
further developed by using different methods either by fuzzy controller or pid
controller.
