Regenerative braking

nounStandard termAutomotive

A system that slows a vehicle by converting its kinetic energy into electrical energy.

A braking mechanism used in electric and hybrid vehicles where the electric traction motor is run in reverse to act as a generator. When the driver lifts off the accelerator or presses the brake pedal, the resistance of the generator slows the car down while sending electricity back to the high-voltage battery. This extends driving range and drastically reduces wear on the traditional friction brakes.

Heard on the job

If you set the regenerative braking to maximum, you can practically drive with just one pedal.

Do not mix it up with

  • Engine braking: Engine braking uses the internal resistance of a combustion engine to slow down, while regenerative braking uses an electric motor to generate power.
