Last week, experts from Europe’s mobility and energy sectors came together for the STF-D4E-CoW workshop on roles and user scenarios, hosted by the European Commission. The goal was to create a shared understanding of the roles and responsibilities required for smart and bidirectional charging and to discuss the most relevant user scenarios across Europe. The workshop featured Guilherme Crispim Ferreira from CharIN.
CharIN´s participation
Representing CharIN, Guilherme Crispim Ferreira took part in the STF-D4E-CoW workshop on roles and user scenarios, which brought together experts from Europe’s mobility and energy sectors. CharIN contributed by actively contributing to the discussions on the progress on the alignment of functional roles and by framing how these roles support interoperable smart and bidirectional charging across Europe.
Attendees and participants
The workshop brought together representatives from automotive manufacturers, charging infrastructure providers, energy operators, regulators, and EU institutions. Several participants are members and or partners of CharIN, including industry leaders, regulators, and expert networks such as BMW, Ford Werke, Enel X, and ChargePoint. In addition to these CharIN members, the additional key stakeholders present were Energinet, DG ENER, DG MOVE, DG CNECT, Task53, VDI VDE Innovation + Technik GmbH, and ACEA.
Defining roles and responsibilities
During the workshop, participants presented the alignment work on defining key roles. Each of the three expert groups had approached its roles differently. Through discussion, they achieved a joint understanding based on functional roles rather than commercial entities.
Exploring user scenarios
Participants worked on identifying which roles are considered obligatory or important in different user scenarios, with a focus on explicit high-level scenarios that facilitate smart and bidirectional charging in 90% of these use scenarios. The existing use scenarios were split into 3 key groups (All Public Charging, All Private Charging, and Multi-Party), determined by the amount of actors involved in terms of "ownership" of the connected meter, charging point, and car, as well as the degree of "accessibility" as defined in AFIR. For example, one scenario explored how an electric vehicle fleet operator interacts with a grid operator and a charging service provider to enable bidirectional charging, balancing energy flows while ensuring vehicle availability. While there was strong alignment on key roles and responsibilities, the workshop confirmed that further discussion is needed to capture all variations and edge cases.
Key takeaways
- There currently exists a strong foundation and alignment regarding key roles and responsibilities between the mobility and energy sectors.
- There is, however, still a need for further understanding between the sectors, namely, on best defining key user scenarios, with an understanding that more detailed discussions will be necessary to fully understand the different variations that may arise.
- The work done so far is a step in the right direction.
- It is key that this information is easily digestible at a high level, for the key decision makers across the ecosystem, while the intricate details and complexity should be agreed within the technical expert group forums.
"The work being done within the collaboration between the STF-D4E-CoW is a step in the right direction for the further development of e-mobility in Europe. It is imperative that the mobility and energy sectors come together and establish a joint, aligned, high-level understanding on the key roles and responsibilities needed for smart and bidirectional charging."Guilherme Crispim Ferreira from CharIN
Next steps
The workshop represents a significant step in bridging the e-mobility and energy sectors. The insights gained will inform the upcoming joint report and guide decision-making for a harmonized and interoperable smart and bidirectional charging infrastructure in Europe.
