Pan-European EV Charging Roaming Network That Lets Drivers Charge Anywhere Seamlessly

transportPilotedTRL 6

Imagine driving an electric car across Europe and every charging station works with your app and payment card — no extra accounts, no incompatible plugs, no surprise fees. Right now, EV charging networks don't talk to each other, like having a phone that only works on one carrier in one country. NeMo built the "translator" that sits between all these different charging networks, so they can share data and services automatically. It also created an open marketplace where companies can plug in new services — like finding the cheapest charge nearby or scheduling charging when the grid isn't overloaded.

The business problem

What needed solving

EV drivers today face a fragmented charging landscape — different networks require different apps, cards, and accounts, and none of them talk to each other across borders. This lack of interoperability frustrates consumers, limits market growth for charging operators, and creates grid management headaches for energy companies. The result: slower EV adoption across Europe and missed revenue for every company in the charging value chain.

The solution

What was built

NeMo delivered an Open European Inter-Roaming protocol that enables different EV charging networks to exchange data and services automatically, plus Common Information Models that standardize how electromobility data is structured across the industry. These sit within a distributed Hyper-Network architecture and an Open Cloud Marketplace where third parties can offer B2B and B2C services.

Business applications

Who can put this to work

EV Charging Network Operators

mid-size

Target: Charge point operators (CPOs) running regional or national charging networks

If you are a charge point operator struggling with customers who can only use your stations if they have your specific app or RFID card — this project developed an open eRoaming protocol that connects different charging networks across 12 European countries. Instead of building expensive bilateral agreements with every other network, you plug into one interoperable layer and instantly reach all EV drivers. The Common Information Models ensure your data formats translate automatically to any other operator's system.

Automotive & Fleet Management

enterprise

Target: Fleet operators and car manufacturers integrating charging into vehicle services

If you are a fleet manager or OEM dealing with the headache of managing charging across multiple countries and networks for your vehicles — this project built a distributed Hyper-Network with standardized interfaces that lets EVs, charging points, and grid operators exchange data seamlessly. Your drivers get unified identification and payment across Europe, and you get consolidated usage data from a single integration point rather than dozens of separate agreements.

Energy & Smart Grid Services

enterprise

Target: Distribution system operators and energy retailers offering EV-related services

If you are an energy company worried about grid overload from uncoordinated EV charging — this project created an open cloud marketplace where you can offer smart charging and demand-response services directly to EV users and charge point operators. The platform's B2B2C model means you can reach end consumers through existing charging networks without building your own customer-facing infrastructure. The 38-partner consortium across 12 countries already validated the cross-border data exchange.

Frequently asked

Quick answers

What would it cost to integrate with the NeMo eRoaming system?

The project developed open protocols and Common Information Models, meaning the specifications are publicly available — no licensing fees for the standards themselves. Integration costs would depend on your existing IT infrastructure and how many data formats you currently support. Based on available project data, the open architecture was designed specifically to lower the barrier for SMEs and new market entrants.

Can this scale to handle charging networks across all of Europe?

The system was designed from the ground up as a pan-European solution, validated across a consortium spanning 12 countries (AT, BE, DE, EL, ES, FR, HU, IT, NL, PL, RO, SK). The distributed architecture means there's no single bottleneck — each participant connects to the Hyper-Network and data translates dynamically based on the specific scenario. With 26 industry partners involved in design and testing, the protocol accounts for real-world scale requirements.

Who owns the IP and can I use the protocols freely?

NeMo explicitly positioned itself as an open ecosystem, not a proprietary platform. The Open European Inter-Roaming protocol and Common Information Models were developed as public deliverables intended for standardization bodies. Based on available project data, the project actively liaised with standardization bodies to contribute to protocol evolution, suggesting the outputs are intended for broad adoption rather than restricted licensing.

How does this relate to existing roaming solutions like Hubject or Gireve?

NeMo's Hyper-Network was designed not to replace existing platforms but to connect them through dynamic data translation. The open architecture with standardized interfaces means it acts as an interoperability layer between existing proprietary systems. The consortium included 26 industry partners already operating in the electromobility space, suggesting practical compatibility with incumbent solutions.

Is this compliant with current EU regulations on EV charging?

The project was specifically funded under the GV-8-2015 topic addressing green vehicles and transport decarbonisation. NeMo developed Common Information Models incorporating all existing electromobility-related standards with mechanisms to update them as standards evolve. The protocol specifications were designed to feed into EU standardization processes.

What's the timeline to get from evaluation to deployment?

The project closed in September 2019, so the core protocols and information models are already developed and documented across 18 deliverables. An operator with existing IT infrastructure could evaluate the protocol specifications and begin integration planning immediately. Based on available project data, the open architecture was designed for incremental adoption — you can connect to the network without overhauling your entire system.

Consortium

Who built it

This is a heavyweight consortium with 38 partners spanning 12 European countries — one of the larger electromobility projects in Horizon 2020. The 68% industry ratio (26 out of 38 partners) signals this was built with commercial deployment in mind, not just academic research. The geographic spread across Western, Southern, Central, and Eastern Europe (AT, BE, DE, EL, ES, FR, HU, IT, NL, PL, RO, SK) means the protocols were stress-tested against diverse national regulations, grid configurations, and market conditions. The coordinator is a Greek research institute (EREVNITIKO PANEPISTIMIAKO INSTITOUTO SYSTIMATON EPIKOINONION KAI YPOLOGISTON), which provided neutral academic leadership while letting industry partners drive practical requirements. With 4 SMEs in the mix, the project also considered the needs of smaller market entrants alongside the major operators.
