Regenerative braking means that the kinetic energy during braking obstruction is converted to another form of energy, usually electric. Converted energy is stored in batteries and as may later be used for example when starting.
During braking, kinetic energy is thwarted by the vehicle. Through the friction brakes of each car's kinetic energy is transformed into heat energy. Therefore, the brakes must be well cooled. The resulting thermal energy in the brakes, however, escapes without further use.
In contrast, regenerative braking can transform kinetic energy into that kind of energy that can be kept for later use to move the vehicle. This recovery, then back into the energy supply system, it may take various forms. The most commonly kept as electrical energy via batteries or flywheels as kinetic means. Today, similar systems are used in Formula 1 - The KERS (Kinetic Energy Recovery System) .

Modern hybrid cars are designed so that when going downhill or braking allows the electric motor to act as a generator. This allows the car to transform kinetic energy into electrical energy.
