Regenerative braking converts kinetic energy back into stored electricity

Electric motors reverse operation during deceleration to act as generators charging the battery

In electric and hybrid vehicles, regenerative braking uses the electric drive motor as a generator during slowing down. Deceleration forces turn the electric motor, capturing kinetic momentum and storing it as electrical energy inside the battery bank. This mechanism reduces mechanical brake pad wear while increasing overall vehicle driving efficiency.
