Regenerative braking is a system that recovers energy when you slow down and feeds it back into the battery, extending range. When you lift your foot off the accelerator or apply the brakes, the electric motor works in reverse as a generator, converting kinetic energy into electrical energy rather than wasting it as heat (as in conventional brakes).
Many EVs offer adjustable regenerative braking strength — stronger settings allow “one-pedal driving” where you can slow to a near-stop using only the accelerator pedal, rarely needing the brake pedal in normal driving.
