Regeneration — sometimes shortened to regen — is the process by which a Formula 1 car captures wasted energy and converts it into electricity stored in the battery. This mainly happens under braking, where the MGU-K acts as a generator to convert the car’s kinetic energy. The MGU-H also regenerates energy from the turbocharger’s exhaust flow. The regenerated energy is then available to be deployed as extra power at a later point in the lap. Regeneration is a continuous, managed process happening on every lap.
Example: He’s in a heavy regeneration phase through the infield — storing that energy for the power sensitive sections.
Regeneration and harvesting are the same thing — both terms describe the capture and storage of electrical energy during the lap. They are used interchangeably.
