6. Introduction
Key feature :
Environment friendly
 Petrol and diesel use is destroying our planet
 Convenience of charging at home
 Electric Vehicles are easy to drive and quiet
 Tax and financial benefits
 Lower running costs
Why EVs / HEVs ?
 Range
 Temperature sensitive batteries / Safety
 Charging time
 Cost
 Efficiency
Problems with EV / HEV ? Biggest draw bag :
Market cost and Safety

7. Timeline of EVs
1831
Invention of
Electric motor
1839 First pure EV
Invented 1992 First EV by
Toyota
2000 The Toyota Prius
becomes the first
hybrid electric
vehicle to be sold
worldwide
2022 Automakers around
the world continue
to set goals toward
increasing EV and
hybrid production
2010
.
More advanced battery
technologies, charging
infrastructure, and a
focus on the environment
play a crucial role in the
push for E Vs.

8. Regenerative Braking System
Regenerative braking system is
an energy recovery mechanism that slows
down a moving vehicle or object
by converting its kinetic energy into a form
that can be either used immediately or
stored in battery .
 The most common form of regenerative
brake involves an electric
motor functioning as an electric
generator.
 In this mechanism, the electric traction
motor uses the vehicle's momentum to
recover energy that would otherwise be
lost to the brake discs as heat .

Energy saved by regenerative braking in different vehicles
Key Parameter : “If regenerative braking can have a net benefit, it would be on a heavy vehicle such as a Routed bus because of the
frequent stop and go requirements for both traffic light and passengers.”

10. Advantages of RBS
1
Brake Pads & Rotors May Last Longer
since regenerative braking does much of the work while
slowing the vehicle, the brake pads and rotors are used much
less frequently.
2 Extended range possibilities for EVs
Estimations show that regenerative braking can potentially add
hundreds of miles of electric driving range throughout the year..
3
Better fuel efficiency
Regenerative braking helps keep the battery pack charged, so
drivers don’t have to rely on their engines as often, helping them
reduce fuel consumption and save money..
4
Energy saving
In case of regenerative braking, a part of electrical energy is
returned to the supply system, so the total energy consumption
for the run in electric traction is considerably reduced (about 20 to
30%). Consequently, a considerable saving in the operating cost.

19. CONCLUSION
Regenerative braking system
has a vast scope for further
development and energy
savings.
A proper implementation of
regenerative braking system extends
driving range, improves braking
efficiency, reduces brake wear, and
improves energy conservation.
Regenerative braking conserve
energy lost during conventional
braking and this braking system
can operate at high temperature
operating range and efficient than
other braking system .
The use of more efficient
systems could lead to huge
savings in the economy of
any country..
Conclusion

20. FUTURE SCOPE
. As the time passes, designers and
engineers will perfect regenerative
braking systems, so these systems
will become more and more common
Future technologies in
regenerative brakes will include
new types of motors which will
be more efficient .
Problems are expected as any new
technology is perfected, but few future
technologies have more potential for
improving vehicle efficiency than does
regenerative braking
Regenerative braking systems
require further research to develop
a better system that captures more
energy and stops faster .
New drive train designs which will
be built with regenerative braking in
mind, and electric systems which will
be less prone to energy losses.
