Our energy future began with a cup of coffee. However, the electricity for this did not come from a distant power station – but from an electric car in the underground car park. In 2015 in the first German vehicle-to-grid (V2G) pilot project ever, the technology company used the battery of a Nissan Leaf as an additional energy source for the home network of its building.

As the world increasingly embraces electromobility, the need for secure and efficient charging systems becomes ever more critical. ChargePilot, a modern control system for charging electric vehicles, deliberately uses the Open Charge Point Protocol (OCPP) and avoids the insecure Modbus protocol. Data security in charging infrastructure is a central concern, as highlighted by recent studies and reports. A key principle in modern IT security is the Zero Trust Policy, which is particularly crucial in integrating charging infrastructures with the energy market and critical infrastructure.

The year 2023 marked a turning point: Bidirectional charging gained momentum in Germany. Our own projects demonstrated the successful functionality of this charging technology today. However, there is still a lack of legal frameworks enabling its practical application. These are essential for the vehicle-to-grid technology to take off. Recognizing the urgency of the issue, policymakers must now implement concrete measures and provide clear signals. The time to act is now. Let's look back at the progress made. One thing becomes clear: We are only just at the beginning of an exciting phase on the path to the upcoming energy transition.

A total of 681,410 electric cars were registered in 2021. This means that the percentage of new vehicle registrations involving electric cars has more than doubled since 2020. This increase also means that an increasing number of charging facilities, such as wallboxes in the private sector, are being installed and registered with the grid operator.

Why smart charging and energy management is vital for the successful electrification of your bus fleet

The German government has decided to introduce the "right to a wallbox", which will allow residents of WEGs to have private charging stations on parking spaces.
