Europe’s rules for connecting vehicle-to-grid charging infrastructure to the electricity system are entering an important phase, as industry stakeholders push for harmonised and open communication standards between charging infrastructure and electricity-system operators.<\/p>\n

Key development:<\/strong> The Open Charge Alliance has asked European policymakers to explicitly recognise open communication standards, including IEC 63584, as the European Union updates grid-connection requirements that extend into electricity storage and vehicle-to-grid applications.<\/p>\n<\/div>\n

\n

Key facts<\/strong><\/p>\n

Consultation deadline:<\/strong> August 25, 2026<\/p>\n

Protocol:<\/strong> OCPP 2.1<\/p>\n

IEC standard:<\/strong> IEC 63584-210:2025<\/p>\n

Industry issue:<\/strong> Communication between V2G EVSE and electricity-system operators<\/p>\n<\/div>\n

European grid rules are expanding into V2G<\/h2>\n

On July 30, 2026, the Open Charge Alliance (OCA) announced that it had submitted a contribution to the European Commission’s public consultation on a draft Delegated Regulation establishing a revised Network Code on Requirements for Grid Connection of Generators.<\/p>\n

The proposed revision is relevant to the EV charging industry because its scope extends beyond conventional generation to electricity storage and vehicle-to-grid applications.<\/p>\n

The consultation is scheduled to remain open until August 25, 2026.<\/p>\n

Vehicle-to-grid, or V2G, changes the role of an electric vehicle from a conventional electricity consumer into a potentially flexible energy resource. Depending on the technical configuration, market structure and applicable grid rules, an EV may adjust its charging schedule or return electricity from its battery to a building or electricity system.<\/p>\n

That creates a more complex communications environment than conventional EV charging.<\/p>\n

OCA identifies a communication gap<\/h2>\n

According to OCA, the current draft does not sufficiently define the communication interface between V2G electric vehicle supply equipment and the relevant electricity-system operator.<\/p>\n

The organisation argues that an undefined interface could result in individual system operators adopting their own technical and cybersecurity requirements.<\/p>\n

If that happens, charger manufacturers, charging-network operators and software providers could face different implementations in different European markets, increasing integration complexity and potentially reducing interoperability.<\/p>\n

\n

Regulatory status:<\/strong> OCA’s recommendations are an industry contribution to an ongoing European regulatory consultation. They are not final EU legislation and should not be described as mandatory requirements at this stage.<\/p>\n<\/div>\n

IEC 63584 moves into the policy discussion<\/h2>\n

OCA recommends explicitly naming IEC 63584 as the communication protocol for relevant system-operator data-exchange interfaces, including interfaces involving V2G charging equipment, electricity storage modules and power-generating modules.<\/p>\n

The organisation also proposes referencing the OCPP 2.1 Certification Programme in national compliance schemes.<\/p>\n

The objective, according to OCA, is to provide a more harmonised route for manufacturers and charging operators to demonstrate compliance instead of requiring different system-operator-specific approaches.<\/p>\n

OCA additionally recommends recognising standardised IEC 63584 security mechanisms in the context of cybersecurity requirements and supporting remote adjustment of relevant grid-code parameters.<\/p>\n

Remote adjustment could become important for deployed charging equipment because grid requirements can evolve during the operational lifetime of an EV charging station.<\/p>\n

OCPP 2.1 is now an IEC standard<\/h2>\n

The standards discussion is taking place after another significant development for the EV charging industry.<\/p>\n

OCPP 2.1 Edition 1 was officially published by the International Electrotechnical Commission as IEC 63584-210:2025<\/strong>.<\/p>\n

OCPP 2.1 builds on OCPP 2.0.1 and introduces functionality designed for more advanced charging environments.<\/p>\n
