The energy of the braking vehicle can only be used by other vehicles for acceleration if the braking and accelerating processes overlap.

The energy storage absorbs the braking energy of vehicles and the energy can be given off after a time lag to the system.

• Absorption of the surplus energy of braking vehicles
• Storing of this energy
• So the energy remains available for accelerating vehicles
• Benefit: Cost reduction due to redcution of the energy consumption
