Elektrofahrzeuge: „Smart Charging“ als Schlüssel für ein nachhaltiges Stromnetz

23. April 20

Eine Elektrifizierung des Verkehrs würde zu einer erhöhten Stromnachfrage führen und hätte damit bedenkliche Auswirkungen auf die Stromversorgungssysteme. Daher bedarf es einer intelligenteren, nachhaltigeren Art der Stromversorgung sowie eines nachhaltigen elektrischen Managementsystems. Genau diesem Thema widmet sich der Beitrag „Electric Vehicle Smart Charging is the Key to a Sustainable Grid” von Alexis Wisdom. Erläutert werden das sogennante Smart Charging und notwendigen Infrastrukturen und Maßnahmen auf europäischer Ebene, die es für eine erfolgreiche Implementierung bedarf.

Electric vehicles are becoming a staple in the increasingly modern and sustainable world. They not only benefit decarbonization and improve air quality, but also allow users to control the power system, with the added benefit of allowing for the usage of renewable energy. However, transport electrification inevitably comes with concerns over the effects on power systems. Because the demand for power would increase substantially because of electrification, a smarter, more sustainable way to power is necessary. Furthermore, power grid congestion and power line overloads are a very real threat without a sustainable electric management system. The alternative, dubbed smart charging, manages charging efficiently so as to not undermine the power grid.

In short, smart charging, a system where EVs and charging devices share data, is essential to the efficiency and future of the energy market. It allows users to optimize energy consumption, while customizing their charging device to their preferences. Smart charging also allows EVs to give back to the grid when renewable energy is deficient. Though it is a necessary solution to negative impacts on the power grid, smart charging needs more administrative attention and accompanying infrastructure. Although the EU has introduced the Clean Energy Package, it is not enough to promote smart charging. There is not enough information on the number of electric vehicles or their respective market and there are not enough internationally recognized standards or protocols.

With the need for smart charging comes a simultaneous need for the accompanying infrastructure. In order for new infrastructure to be introduced, the European Commission must act and develop necessary policies that follow EU regulatory requirements. They must advocate for usage of smart charging and promote it through public incentives. Furthermore, power inverters must be stabilized and data from users must be transparent. Communication interfaces need to adopt protocols and create international standardization. Though the International Electrotechnical Commission (IEC) is a start, many other standards or European bodies need to be introduced and developed.
