Increase storage capacities

Storage capacities in the overall system are increased by e-vehicles, thereby achieving efficient integration of renewable energies.

Achieve power grid stabilization

Grid stabilization can be achieved through the control power of bidirectional charging.

Saving investment costs

An overload of the distribution network due to charging of e-vehicles can be counteracted. This reduces investment costs for the infrastructure.

Reduce load peaks

Load peaks can be significantly reduced, saving companies money (in the form of grid fee reductions).

Bidirectional charging communication enables new business models.

A major component in the success of electromobility is an intelligent power management. Only dynamic energy management can help with a increasing number of electric vehicles, help to keep the infrastructure costs of the power grid limited. This requires bidirectional communication between the e-vehicle and the wallbox. From this point of view e-cars are no longer viewed solely as electricity consumers, but also as storage instances in an overall system. Specially in combination with renewable energies, this is becoming increasingly important. In this context, charging and battery management of e-vehicles is becoming an important new topic area, which we at VISPIRONSYSTEMS are already actively shaping.

V2G - Vehicle to Grid

Systems in which electricity from vehicle storage is fed back into the power grid are referred to as vehicle-to-grid (V2G) systems.
Such a system places high technical demands on both the e-car and the charging station.

V2H - Vehicle to Home

Systems in which electricity from vehicle storage is fed back into the home grid are called vehicle-to-home (V2H) systems. Surplus energy from PV systems can be temporarily stored in the vehicle battery and later fed back into the household grid for consumption.

Help determine the development of a pioneering technology.

The effective and efficient charging and battery management of EVs (Electric Vehicles) is becoming an important new core competence in automotive engineering. Successful influence in standardization work for OCPP and ISO 15118 in the relevant charging communication committees will allow you to actively shape this area.

Logo Open Charge Alliance

Since 2022 VISPIRON SYSTEMS is a member of the Open Charge Alliance.

The Open Charge Alliance (OCA) develops the internationally established communication protocol OCPP for the control, monitoring and configuration of charging stations by their operators.

The OCPP and ISO 15118 will lead the way for the development of new charging technologies.
