An Interoperability Framework for electromobility (INFRA): The main results from the USER-CHI framework implementation in a new spotlight

In 2021 the number of electric vehicles in the European Union (EU) was higher than ever before. Therefore, the charging infrastructure in Europe has many challenges. The EU project USER-CHI (user centric charging infrastructure) aims at devising the basic guidelines for an interoperable charging infrastructure in INFRA (Interoperability Framework). The first part of the paper is about the main results from the framework. The second part presents additional desk research. This allowed for the identification of new aspects that were not, or only superficially, considered during INFRA.

As result, the most important aspect to achieve interoperability in the EU is a user friendly charging infrastructure. It needs to fill the gaps in the European legislation and transfer them into national legal frameworks, otherwise it causes wide disparities between countries.
