Vehicle-to-Grid: A crucial contribution to the energy transition

Vehicle-to-Grid (V2G) is the key to efficient and cheap power supply with renewable energies. Our interactive tool makes the technology’s potential visually tangible.

What is Vehicle-to-Grid?

In Germany, CO2-free power supply works mainly via wind and solar energy. In order to ensure a permanent supply on an industrial scale, large, flexible energy storage is required.

Vehicle-to-Grid can provide this capacity easily, cheaply and efficiently. The batteries of electric vehicles are connected, creating a distributed and smartly controlled buffer storage.

LADE’s interactive V2G simulator helps you modelling the future of power supply both easily and technically well-founded. Based on real world data from the Bundesnetzagentur (German Federal Network Agency), the tool shows that almost the entire power supply in Germany can be guaranteed with wind power, solar energy and electric cars with bidirectional functionality.

Why is Vehicle-to-Grid worthwhile?

The future of individual transport is electric. This automatically creates a gigantic, distributed and mobile energy storage system. Exploiting this potential using V2G is highly rational, both ecologically and economically.

Private cars are parked most of the time and mainly are used for short trips. This creates ample room for network management. Smart control systems ensure sufficient battery levels at all times.

Because stable networks have high economic value, this can be extremely attractive financially for vehicle owners. In order to implement this, the political and regulatory conditions must be set today!

How can Vehicle-to-Grid be implemented?

In order for V2G to work, parked vehicles must always be connected to the grid – therefore, more charging points than vehicles are needed. Economically reasonable, this can only be realised with AC charging infrastructure.

Bidirectional charging with DC chargers creates significantly higher costs in production and operation. The infrastructure would consume vast amounts of subsidies or be limited to few use cases such as private homes. Only a tiny fraction of the available storage capacity could be used.

BEV, on the other hand, can be equipped for bidirectional AC charging with very little effort – if the onboard chargers needed isn’t already installed, anyway. Smart, networked charging infrastructure facilitates communication between network operators, vehicles and drivers.
