Normally, the braking system for a car iscentered on hydraulic braking technology. However, thistraditional braking approach causes a lot of wastage of energysince it produces undesirable heat energy during the braking action.Consequently, the invention of regenerative braking in electricvehicles has overcome these disadvantages moreover it helpsto save energy and increase efficiency for the vehicles.Wheneverbrakes are applied, a significant amount of kinetic energyislost in the form of heat energy due tofriction between brake pads and rotor. RegenerativeBraking System recovers kinetic energy as much aspossible that is wasted during the process of braking. The energy is stored and then released under acceleration. Thispaper highlights the two different methods of recoveringenergy, by converting it intoeither electrical or mechanical energy. The kinetic energygets converted into electrical energy with the help ofelectric motor while flywheel harnesses the kineticenergy by converting it into mechanical energy.
