The Regulatory Imperative: AFIR Drives ISO 15118 Adoption
The Alternative Fuels Infrastructure Regulation (AFIR) is the primary catalyst for standardizing the European EV charging ecosystem. Annex II of AFIR explicitly mandates that all DC charging stations above 50 kW deployed along the Trans-European Transport Network (TEN-T) core network must support ISO 15118-2 or ISO 15118-20 by April 13, 2026. This is not a suggestion but a legal requirement for new installations, fundamentally reshaping the technical roadmap for every Charge Point Operator (CPO) on the continent.
For CPOs and energy operators, this means that Plug & Charge (PnC) capability is transitioning from a premium differentiator to a baseline compliance feature. The regulation is designed to eliminate friction for cross-border travel and create a seamless, automated user experience that is critical for mass EV adoption.
Understanding the ISO 15118 Standard: More Than Just Automation
ISO 15118 is often synonymous with Plug & Charge, but its scope is far broader. This standard defines the digital communication between an Electric Vehicle (EV) and a Charging Station, enabling:
The shift from ISO 15118-2 to the more advanced ISO 15118-20 standard is already underway, offering improved security and support for V2G functionalities. "
The 2026 Timeline: Key Milestones for European CPOs
With the April 2026 deadline for TEN-T corridors approaching, a clear timeline for implementation is essential for strategic planning.
| Timeline | Milestone | Impact for CPOs & Operators |
|---|---|---|
| Now - Q4 2025 | Preparation & Procurement | Finalize technical architecture, select vendors, and initiate hardware/software upgrades. |
| Q1 2026 | Pre-deployment Testing | Rigorous testing of the entire PnC chain, from the charging station's Secure Element to the CSMS's certificate management. |
| April 13, 2026 | AFIR Mandate Live | All new DC chargers (>50kW) on TEN-T core networks must be PnC compliant. |
| 2027 onwards | Network Expansion & V2G Readiness | Roll out PnC across entire networks and begin implementing ISO 15118-20 for smart charging and V2G services. |
This timeline is aggressive. The backend integration, particularly the PKI ecosystem involving Root Certificate Authorities (Root CA), Contract Certificate Authorities (MO/CPO CA), and the necessary OCPP communication between the charger and CSMS, requires significant lead time.
Interoperability: The Core Challenge for Network Orchestration
True PnC interoperability is the holy grail. A driver must be able to plug in at any compliant station across Europe, regardless of the CPO or eMobility Service Provider (MSP). Achieving this requires flawless technical execution across three layers:
1. Hardware: Charging stations must have a compatible Secure Element and support OCPP 2.0.1 or later.
2. Backend (CSMS): The backend system must act as a certificate provider, managing the entire lifecycle of digital certificates for EVs and handling complex billing reconciliation.
3. Roaming: Interoperability across roaming platforms (e.g., e-clearing.net, Gireve) must be established to share certificate information and authorize sessions between different operators.
Failure at any point in this chain results in a failed session and a frustrated driver. This is where a robust CSMS and a deeply integrated OCPP stack become invaluable assets.
Strategic Actions for CPOs and Fleet Managers
For heads of charging and operations, simply meeting the deadline is not enough. Strategic advantage comes from leveraging PnC.
Beyond Compliance: PnC as a Foundation for Grid Intelligence
ISO 15118 Plug & Charge is more than a convenience feature; it is the foundational protocol for the next generation of smart charging. By enabling secure, bi-directional communication, it paves the way for AI-driven energy management. An GFO Omni platform can use this data link to dynamically optimize charging schedules in real-time based on grid constraints, energy prices, and renewable energy availability, turning a charging network into a virtual power plant (VPP).
For operators managing diverse hardware, achieving universal PnC compliance can be a challenge. This is where advanced interoperability solutions show their value. GreenFinOps' OCPP translation layer built into GFO Omni, a proprietary compatibility engine, seamlessly integrates legacy charging assets into modern ISO 15118 and AI-driven operations layer ecosystems, future-proofing your infrastructure investment.
