Vehicle To Grid

Vehicle to Grid - from the car to the grid

Do you know the feeling when your smartphone battery is almost empty and you wish someone nearby could give you some of their energy?
Imagine if your electric car could do just that for the power grid. This is called "vehicle to grid" or bidirectional charging.

What is Vehicle-to-Grid (V2G) or bidirectional charging?

V2G refers to the technology in which electric vehicles not only draw electricity from the grid, but can also feed it back into the grid. It is as if your car not only consumes electricity, but also becomes a small power plant.

What are the advantages of Vehicle-to-Grid (V2G)?


Energy stabilization

Electric vehicles (EVs) can act as energy storage units and feed electricity back into the grid as required to cushion peak loads and stabilize the grid.


Renewable energies

V2G enables better integration of renewable energies. If surplus solar or wind energy is available, for example, it can be stored in the electric vehicle and fed back into the grid later.


Profitability for electric vehicle owners

The ability to feed surplus energy back into the grid can provide EV owners with an additional source of income by being remunerated by the local energy supplier for feeding electricity back into the grid.


Reducing investment in energy storage

As EVs can act as decentralized storage, the need for large, centralized energy storage systems such as batteries is reduced, leading to cost savings in the energy sector.


Resilience in emergencies

In the event of power outages or other interruptions to the power grid, vehicles with V2G technology can serve as a temporary power source for critical infrastructure or households.

How does V2G work?

V2G requires a bidirectional charging infrastructure that enables both charging and discharging of the vehicle.
Invisia provides this infrastructure and can help you feed electrical energy from your electric vehicle back into the grid.

Where is the Energiemanagementsystem (EMS) used?

Invisia’s EMS determines when it is best to charge a vehicle or feed energy back into the grid.

Factors such as:

  1. the current and expected electricity price
  2. the state of charge of the battery
  3. the expected driving demand
  4. the state of the electricity grid

FAQ about Vehicle to Grid (V2G)

What is the main difference between normal charging and V2G?

With normal charging, the car only draws electricity. With V2G, it can also feed electricity back into the grid.

Is V2G harmful to my car’s battery?

With the right technology and management, there should be no negative effects.

Is V2G the future of energy?

It is a promising step in this direction, but will be used in combination with other technologies.

Where can I see V2G in action?

Invisia has already implemented several pilot projects. We would be happy to show you how V2G works in practice.
