For power generating technologies such as wind and PV so-called grid codes have been providing the technical framework for their grid connection for the last 25 years. These grid codes impose important requirements on the electrical characteristics of these installations in order to ensure as reliable and secure operation of the power system as these new generation technologies take over the dominant role of power supply and, hence, of ancillary services to the power system.

The growing fleets of electric vehicles (EV) with still rising load capacities up to several 100 kW and now coming up bi-directional coupling to the power grid requires also to integrate these prosumers into the scope of respective connection codes. Hence, in the previous years, some European countries have already published initial requirements on the grid connection capabilities of EVs and respective charging systems.

Accordingly, the European Network Codes, initially published in 2016 without having EVs in their scope, will also address respective grid code requirements for EVs and charging installations within the next revision expected in 2025.

After an introduction to the basic objectives and scope of grid codes and, in particular, the European Network Codes, the presentation provides an overview on the new requirements for EVs and charging systems as announced in the revised European Network Codes. The requirements will be distinguished between uni- and bi-directional couplings and also between the three capacity-based types of bi-directional EVs defined by the Network Codes. The paper will also provide an introduction to respective compliance schemes as stipulated in the Network Codes.
