Brake Energy Regeneration.
Until now, braking had meant giving away energy. Brake Energy Regeneration puts an end to this by using energy gained during braking to charge the battery.
As soon as you release the accelerator or apply the brake, Brake Energy Regeneration uses the energy liberated to charge the battery. This unburdens the engine and reduces emissions.
The targeted generation of electrical energy also has another advantage: At full acceleration, the engine also has the propulsive force at its disposal that would otherwise be channelled off to charge the battery in conventional systems. The result is an increase in not only cost-efficiency but also driving fun.
