Introduction to Regenerative Braking System:

       A brake is a tool that enables in deceleration of a moving object; they use friction to convert kinetic energy into heat. Conventional braking systems use this mechanism. Once the brake pads rub against the wheels of the car, excessive heat energy is produced. The heat generated is lost into the air nearly accounting for about 30% of the car’s generated power. The project here “Regenerative Braking System Project For Mechanical Students” introduces a different braking technology.

         In this system, regenerative braking mechanism reuses the energy created by the braking process and uses this energy to charge the battery for further use. Generally the energy lost in the conventional use is transferred to the generator of the rotating wheel and is given to the battery. This saves a lot of energy.


        The driving system of the vehicle is responsible for most of the braking process. As soon as the driver steps onto the brake pedal of the vehicle (either hybrid or electrical), the brakes put the vehicle’s motor in the reverse mode enabling it to run backwards causing the wheels to slow down. While in the reverse mode, the motor operates as an electric generator feeding this electricity into the vehicle’s batteries.

     Most of the hybrid and electric vehicles in the market employ this technique to extend the life span of the battery pack. It is highly beneficial to use regenerative mechanism as it reduces pollution and also increases the engine life.


        In this project Regenerative Braking system, the regenerative brake captures about half of the energy wasted and is utilized by the engine whereas in conventional brakes, 80% energy is wasted. Hence fuel consumption is reduced by 10 to 25 percent in regenerative braking. Not only this, speed of the vehicle is also greatly enhanced by this mechanism of braking.
