Designing of electric vehicle with regenerative braking system

India is the world's top producer of two-wheelers, which are frequently used in our daily lives. However, after a few years of service, the engine loses its efficiency and can no longer meet the environmental protection regulations. If these scooters could be transformed into electronic scooters, they could be used for a longer period of time. In this paper, an ordinary two-wheeled Honda Activa Scooter model powered by a two-stroke gasoline engine was converted into an electric vehicle. To increase efficiency, a novel approach known as regenerative braking was implemented. Regenerative braking temporarily conserves kinetic energy during deceleration and then uses it again as kinetic energy, thereby reducing fossil fuel consumption. When braking, a large amount of energy is typically lost as heat, but the regenerative braking system recovers this energy. With this system, the electric motor uses the vehicle's momentum to recover the energy lost while braking.
