Regenerative braking is a pivotal innovation in the design of hybrid vehicles, significantly enhancing their energy efficiency and overall performance. Unlike conventional braking systems, which rely solely on friction to decelerate a vehicle, regenerative braking captures a portion of the kinetic energy that would otherwise be lost as heat and converts it into usable electrical energy. This recovered energy is then stored in the vehicle's battery for later use, which reduces the overall demand on the internal combustion engine or the primary electric motor. By integrating regenerative braking into hybrid vehicles, manufacturers achieve substantial improvements in fuel economy, reduced emissions, and prolonged battery life, making it a key technology in the pursuit of zero-emission mobility. The fundamental mechanism of regenerative braking revolves around the electric motor functioning as a generator during deceleration. When a driver applies the brakes, instead of purely engaging friction brakes, the electric motor reverses its role and begins to convert the vehicle’s kinetic energy into electrical energy. This process inherently slows down the vehicle while simultaneously charging the onboard battery. In hybrid vehicles, this dual-purpose system allows the car to leverage both mechanical and electrical energy management efficiently. The amount of energy recovered depends on several factors, including vehicle speed, battery state-of-charge, motor efficiency, and braking intensity. Advanced hybrid systems can optimize regenerative braking by blending it seamlessly with traditional friction braking to ensure
