Sys. Advantages and Disadvantages of RBS Conclusion and References.;A?Regenerative Brake,?is an?energy recovery mechanism which slows a vehicle or object down by converting its?kinetic energy?into another form, which can be either used immediately or stored until needed. A Traditional Braking System,?brake pads?produce friction with the?brake rotors?to slow or stop the vehicle. Additional friction is produced between the slowed wheels and the surface of the road. This friction is what turns the cars kinetic energy into heat. ;HISTORY; The “Energy Regeneration Brake” system was developed in 1967 by American Motors Corporation (AMC) in cooperation with Gulton Industries. The Energy Regeneration from braking idea was later commercialized by the Japanese and both Ford Chevrolet licensed it from Toyota for use in their domestic built hybrid Vehicles. During the late 2000s, an electronic control unit used by BMW that engages the alternator during braking.;Law of Conservation of Energy?states that the total?energy?of an?isolated system?cannot change it is said to be conserved?over time. Energy can be neither created nor destroyed, but can change?form, for instance?chemical energy?can be converted?to?kinetic energy?in the explosion of a stick of?dynamite. The most common form of regenerative brake involves using an?electric motor?as an electric generator. ?the generated electricity is fed back into the?supply system, whereas in?battery electric?and?hybrid electric?vehicles, the energy is stored chemically in a?battery; NEED OF REGENERATIVE BRAKING ; WORKING OF REGENERATIVE BRAKING SYS.;Fig.-1 Regenerative Braking circuit; REGENERATIVE BRAKING SYSTEM IN HYBRID VEHICLES;Fig.-2 Circuit Dig. of Reg.
