3. Friction is used for braking . Excessive heat energy is created during braking . This heat energy dissipates into the air wasting as much as the vehicle 80% of the vehicle generated power Conventional Braking reduced fuel efficiency. Regenerative Braking Systems 1.

4. Regenerative braking means recapturing the kinetic energy of the vehicle motion and turning into another energy during braking. Commonly , kinetic energy is converted into electric energy This energy is stored in storage battery and used later to power the vehicle in hybrid or fully electric vehicles.

5. In 1908 C.J. Paulson Patented a smart car with Regenerative Braking System. The “Energy Regeneration Brake” system was developed in 1967 by American Motors Corporation (AMC) in cooperation with Gulton Industries . During the late 2000s, an electronic control unit used by BMW that engages the alternator during braking.

6. In most electric and hybrid electric vehicles on the road today, this is accomplished by operating the traction motor as a generator, providing braking torque to the wheels and recharging the traction batteries.

7. In low-speed , stop-and-go traffic where little deceleration is required; the regenerative braking system can provide the majority of the total braking force. This vastly improves fuel economy with a vehicle, and further enhance the attractiveness of vehicles using regenerative braking for city driving . At higher speeds, too, regenerative braking has been shown to contribute to improved fuel economy - by as much as 20%. Sangeet Khule/Regenerative Braking System/Techical Seminar/2020-21 7 /30 3.

10. By applying brakes, the electric motors coupled with drive wheels, rotated in reverse mode slowing down the car’s wheels. A properly designed motor becomes an electric generator, converting into electrical energy. This energy is feeding back into storage battery and used to accelerate the vehicle.

11. Energy Storage Unit (ESU) : The ESU performs two primary Functions: To Recover & Store Braking Energy. T o absorb excess engine energy during light load operation. The Selection Criteria for an effective energy Storage includes. High specific energy storage density . High energy transfer rate . Small space requirement. The Energy recaptured by regenerative braking might be stored in one of three devices , an Electrochemical battery, a Flywheel, & a Hydraulic Accumulator.

14. Improved Performance . Emission Reduction . Reduction in Engine Wear . Increase of overall energy efficiency of a vehicle . Cuts down on pollution related to electricity generation. Increases the lifespan of friction braking systems. Smaller Accessories . Less use of traditional mechanical brakes leads to less wear over time Sangeet Khule/Regenerative Braking System/Techical Seminar/2020-21 14 /30 6. ADVANTAGES OF REGENERATIVE BRAKING SYSTEM

15. Added Weight-Extra components can increase weight . Complexity -depends on control necessary for operation of regenerative braking system. Cost of components, engineering, manufacturing and installation is high . Friction brakes are still necessary . Safety-Primary concern with any energy storage unit of high energy density. Added maintenance requirements dependent on the complexity of design. Sangeet Khule/Regenerative Braking System/Techical Seminar/2020-21 15 /30 6. DISADVANTAGES OF REGENERATIVE BRAKING SYSTEM

26. 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 Regenerative braking conserve energy lost during conventional braking Regenerative braking system has a vast scope for further development and energy savings. Sangeet Khule/Regenerative Braking System/Techical Seminar/2020-21 26 /30 8. CONCLUSION

27. As regenerative braking save up to 50 % of energy new inventions can be discovered in the form of new electricmotors 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.
