Vehicle-to-Grid (V2G) certification for grid integration

Electric car batteries can do more than just power cars!

By 2030, there will be 140 to 240 million electric vehicles worldwide. This means that we will have at least 140 million tiny energy storage devices on wheels with a total storage capacity of 7 TWh. All well-known car and charger manufacturers are developing new models with V2G technology.

Thanks to our accreditation as a testing laboratory and certification body and our international contacts, we can provide you with globally recognized test reports and certificates as proof of compliance with standards. We have carried out the world's first V2G certifications for renowned automobile manufacturers.

What is vehicle-to-grid?

V2G (Vehicle-to-Grid) refers to the bidirectional charging of electric vehicles. In this process, the vehicle is not only charged, but also used as a temporary battery storage device to feed the stored energy into the power grid or the energy system of the home. V2G is the next logical step following smart charging (Grid-to-Vehicle) and enables grid-friendly charging of electric vehicles.

What other areas of application are there?

V2X (vehicle-to-everything) is a collective term for various sub-forms of feeding electricity back from vehicles and includes, among other things:

V2B (vehicle-to-building): Avoiding peak power consumption for companies with their own electric vehicle fleet.

V2H (Vehicle-to-Home) - temporary storage of electricity from a PV system for single-family home owners,

V2V (Vehicle-to-Vehicle) - energy exchange between two or more electric vehicles,

V2L (Vehicle-to-Load) - operation of electrical appliances with power supplied directly from the vehicle.

How does vehicle-to-grid work?

Electric vehicles are connected to the public power grid via a bidirectional charger. This V2G charger allows electricity to flow in both directions, enabling the electric vehicle to temporarily store excess electricity from the grid when needed, but also to feed it back into the grid later.

Vehicle-to-grid technology thus serves as load management for the public power grid, helping to balance the grid and prevent power outages or other disruptions. Electric vehicles become an active part of the power grid and must comply with future grid code standards.

What are the advantages of vehicle-to-grid?

Controlled charging cycles at times when prices are lower
Electricity storage for times when there is no solar or wind energy generation
Reduction in overall costs for fleet solutions
Supply of electricity to public charging stations
Grid operators can optimize investments and stabilize the grid
Energy market players can better optimize the balance in the grid
