Eastron Smart Meters with OCMF Compliance: Your Reliable Partner for EU EV Charging Billing

Breaking into the EU Market? Start with OCMF-Compliant Metering

If you're deploying EV charging stations in Europe, you've likely encountered OCMF — a critical compliance standard that can't be ignored. But what exactly is it, and why is it essential for every charging project across the EU?

OCMF isn't just another technical acronym; it's the established open data format that ensures charging sessions are measured accurately, transparently, and in a legally recognized way. In this post, we'll explain what OCMF means for your business and highlight two ready-to-deploy smart meters that are already triple-certified for the European market.

What is OCMF & Why Does It Matter?

OCMF (Open Charge Metering Format) is a standardized data protocol developed by the Open Charge Alliance and SAFE-eV. It was created to solve key challenges in EV charging metering:

- Data Consistency – Provides a uniform “language” for charging data across different hardware and software systems.

- Tamper Evidence – Each metering dataset is cryptographically signed, preventing manipulation and building trust.

- Legal Validity – Designed to comply with strict European regulations such as the EU's Measuring Instruments Directive (MID) and Germany's Eichrecht, enforced by PTB.

In short, OCMF ensures that the energy measured during a charging session can be used for billing and legal purposes across all EU member states.

The Triple Certification: OCMF + MID + PTB

For a meter to be legally recognized in Europe — especially in regulated markets like Germany — it must carry not only OCMF compliance but also MID certification and often PTB approval. This triple mark is what truly unlocks the EU market, reducing time-to-market and compliance risks for operators and OEMs.
