What braking technology lets modern hybrid cars recover energy while slowing down?

Regenerative braking is the braking technology that lets modern hybrid cars recover energy while slowing down.

Instead of turning all the vehicle’s motion into heat through friction, the electric motor reverses its role and operates as a generator. The wheels drive the motor, producing electricity that is sent to the hybrid battery. That stored energy can later help propel the car or power electrical systems.

Regenerative braking does not replace conventional brakes entirely. Friction brakes still handle hard stops, low-speed braking, emergency situations, and times when the battery cannot accept more charge. Vehicle computers blend the two systems so the driver experiences normal braking behavior.

A common mix-up is engine braking, which slows a vehicle through resistance from the combustion engine but does not necessarily recover energy. Anti-lock braking, meanwhile, prevents wheel lock during braking; it is a safety-control system rather than an energy-recovery method.
