Electrical vehicles such as cars, buses, and two-wheelers provide a quiet and comfortable ride powered by rechargeable batteries and electric motors. These batteries can propel the vehicle for distances and times defined by their performance before needing to be recharged. Electrical vehicles are more efficient than gas vehicles partly due to less conversion mechanics and partly due to regenerative braking.

Charging has always been an issue in electrical vehicles. In this project, the kinetic energy is transmitted in the brakes through drive train and is directed by a mechanical system to the potential store during deceleration. That energy is held until required to the vehicle, wherein it is transformed back into energy and stored in the battery of the vehicle. The amount of the power available for conservation varies depending on the type of storage, drivetrain efficiency, and drive cycle and inertia weight. When a normal vehicle applies its brake, its kinetic energy is transformed to heat because of friction between wheels and brake pad. This heat passes through the air and the energy is wasted. The total energy lost in this way depends on how often, long and hard the brake is being applied. An energy conversion action in which a part of the energy of the vehicle is stored by a battery or storage device is known as regenerative braking. Driving within a city involves more braking representing a high loss of energy with the opportunity for savings in energy. In the case of public transport vehicles such as local trains, buses, taxis, delivery vehicles there is even more potential for energy to be regenerated
