The Regulatory Imperative: Why ISO 15118 is No Longer Optional
The era of proprietary charging protocols and fragmented user experiences is drawing to a close in Europe. Driven by the European Union's Alternative Fuels Infrastructure Regulation (AFIR), the ISO 15118 Plug & Charge standard is transitioning from a premium feature to a foundational requirement for all EV charging operators. This mandate is not just about compliance; it's a strategic pivot towards a seamless, secure, and digitally integrated eMobility ecosystem. For CPOs and product leaders, understanding the adoption timeline is critical for capital planning, technology roadmaps, and maintaining a competitive edge.
AFIR establishes clear deadlines for the deployment of smart charging capabilities and ad-hoc payment methods. While the regulation explicitly calls for "communication with the vehicle" to enable smart functionality, the industry consensus is that this will be interpreted through the lens of ISO 15118, the only internationally recognized standard for bidirectional EV-to-charging-point communication. Failure to prepare for this shift risks non-compliance fines and, more importantly, obsolescence in a market where user experience is paramount.
Decoding the ISO 15118 Standard: More Than Just Plug & Charge
At its core, ISO 15118 enables a secure, automated "handshake" between an electric vehicle and a charging station. While the "Plug & Charge" feature (which allows for automatic authentication and billing without RFID cards or apps) is the most visible benefit, the standard's value runs much deeper.

It effectively turns the charging session into a dynamic, negotiable contract."
The European Adoption Timeline: AFIR Deadlines and Market Realities
The AFIR regulation, which entered into force in April 2024, sets a clear, phased timeline for implementation. CPOs must align their hardware and software upgrade cycles with these critical dates.
| Timeline Phase | Key Deadlines & Milestones | Impact on CPOs |
|---|---|---|
| Phase 1: Preparation (2024-2025) | National transposition of AFIR by Member States. | Assess hardware/software readiness. Plan CAPEX for upgrades. |
| Phase 2: New Installations (From April 2025) | All new publicly accessible charging stations must be "smart charging-ready." | Ensure new hardware procured is ISO 15118-compliant. Update CSMS to support the standard. |
| Phase 3: Full Deployment (From April 2027) | All existing public charging stations must be upgraded to support smart charging capabilities. | Execute a retrofit strategy for legacy chargers. Full backend integration for Plug & Charge services. |
This timeline creates a tight window for action. By 2027, the majority of public charging points in Europe will need to support the core communication capabilities of ISO 15118. This is further reinforced by related directives like the Energy Performance of Buildings Directive (EPBD), which promotes smart charging in residential and commercial buildings.
Overcoming the Interoperability Hurdle: The OCPP 2.0.1 Connection
A significant challenge for CPOs is the heterogeneous nature of their charging networks. Many fleets consist of chargers from different manufacturers, running various versions of the OCPP protocol. ISO 15118 functionality is natively supported in OCPP 2.0.1, but what about the vast installed base of OCPP 1.6 devices?
Retrofitting thousands of chargers to OCPP 2.0.1 is a costly and time-consuming endeavor. This is where strategic technology decisions become paramount. Instead of a full-scale hardware replacement, CPOs can leverage interoperability solutions that act as a bridge. For instance, GreenFinOps' OCPP translation layer built into GFO Omni, a proprietary compatibility engine, allows CPOs to enable ISO 15118-like functionalities across mixed-protocol estates. This approach future-proofs existing investments and accelerates compliance without the massive capital outlay of a full network overhaul.
Strategic Advantages Beyond Compliance
Moving beyond the regulatory mandate, early adoption of ISO 15118 offers tangible business benefits:
Preparing Your Operations for the Plug & Charge Era
For CPOs and Heads of Operations, the path to compliance requires a structured approach:
1. Conduct a Network Audit: Inventory all charging stations, detailing their OCPP versions and hardware capabilities for ISO 15118.
2. Develop a Phased Upgrade Plan: Prioritize high-traffic sites and new installations for initial deployment. Create a realistic budget and timeline for retrofitting legacy assets.
3. Evaluate Your CSMS: Ensure your Charging Station Management System can fully support ISO 15118, including certificate management (e.g., via a PKI provider like Hubject) and the processing of smart charging contracts.
4. Plan for the Backend Integration: Plug & Charge requires integration with a Clearinghouse (e.g., Hubject, Gireve) for certificate validation and contract management. Start these discussions early.
5. Upskill Your Team: Train technical and operational staff on the nuances of ISO 15118 troubleshooting and management.
The integration of an AI-driven operations layer can further streamline this transition by automating the management of complex certificate exchanges and optimizing charging schedules based on the new data inputs from ISO 15118-enabled vehicles.
Conclusion: Seamless Charging as the New Standard
The EU's regulatory push for ISO 15118 is a definitive step towards a unified, user-centric charging landscape. For forward-thinking CPOs, this isn't just a compliance exercise but a strategic opportunity to build a more robust, efficient, and profitable network. By proactively embracing the Plug & Charge timeline, operators can turn a regulatory requirement into a significant competitive advantage, ready to meet the demands of both tomorrow's drivers and the energy grid.
At GreenFinOps, our solutions, including the OCPP translation layer built into GFO Omni and GFO Omni platform, are designed to help charging networks navigate this transition smoothly, ensuring interoperability and intelligent management across diverse hardware estates.
