Sushant Patil's presentation discusses regenerative braking systems. It introduces regenerative braking as a mechanism that slows vehicles by converting kinetic energy into electrical energy that can be used or stored. Modern hybrid and electric vehicles often use this technique to extend battery life. The basic idea is that regenerative brakes recapture wasted braking energy and use it to recharge a vehicle's batteries. Applying the brakes in an electric or hybrid vehicle causes the electric motor to run in reverse, slowing the wheels and generating electricity. Regenerative braking provides benefits like increased energy efficiency and reduced pollution and engine wear.

3. INTRODUCTION
• Regenerative brake is an energy recovery mechanism which slows a vehicle
by converting its kinetic energy into another form, which can be either used
immediately or stored until needed. Thus, the generated electricity during the
braking is fed back into the supply system (in case of electric trains), whereas
in battery electric and hybrid electric vehicles, the energy is stored in a
battery or bank of capacitors for later use. Energy may also be stored by
compressing air or in a rotating flywheel.
• An Energy Regeneration Brake was developed in 1967 for the AMC
Amitron. This was a completely battery powered urban concept car whose
batteries were recharged by regenerative braking, thus increasing the range of
the automobile.
• Many modern hybrid and electric vehicles use this technique to extend the
range of the battery pack. Examples include the Toyota Prius, Honda Insight,
the Vectrix electric maxi-scooter, and the Chevrolet Volt.

4. BASIC IDEA OF REGENERATIVE
BRAKES WORKS?
• Regenerative braking is a way of taking the wasted energy from the process of
slowing down a car and using it to recharge the car’s batteries.
• On a normal car, braking simply wastes energy - but with regenerative
braking, some of the energy is able to be reused.
• Regenerative braking systems are common on many modern cars. On petrol
and diesel models, it’s used to charge the battery that runs various ancillary
systems in the car, meaning less work for the engine and less fuel burned. In
these models, brake regeneration can help charge the larger batteries that
directly drive the car.
• Applying the brakes of an electric or hybrid vehicle causes the electric motor
to run in reverse direction i.e. in generator mode. Thereby, it slows down the
wheels.

WORK

6. ADVANTAGES
• Increase of overall energy efficiency of a vehicle .
• Improved performance.
• Cuts down on pollution related to electricity generation.
• Smaller accessories.
• Reduction in engine wear .

7. DISADVANTAGES
• Cost of components, engineering, manufacturing and installation is high .
• Friction brakes are still necessary .
• Added weight- extra components can increase weight .
• Safety –primary concern with any energy storage unit of high energy density .
• Added maintenance requirements dependent on the complexity of design .

8. CONCLUSION
• As designers and engineers perfect regenerative braking systems, they will become
more and more common. All vehicles in motion can benefit from utilizing
regeneration to recapture energy that would otherwise be lost.
• Regenerative braking is an effective method of improving vehicle efficiency and
longevity.
• Is already in use in many EVs.
• The technology to do it exists and is often well worth it .
• Mostly dependent on the wider adoption of EVs or further development of hydraulic
regeneration systems.
