Brake Energy Regeneration.
Until now, braking meant giving away energy. Brake Energy Regeneration now puts an end to this: when you brake, energy is recovered and the battery is loaded.
As soon as you release the accelerator or apply the brake, the energy liberated is used to charge the battery. This decreases the load on the engine, reduces emissions and saves fuel.
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.
