CERTIFICATION

Quickly launch new products, and boost consumer confidence in Europe and beyond with the trusted NMi seal of approval.

Keeping pace with consumer demand for alternatives to traditional fuel combustion engines and the drive to meet environmental sustainability targets — the adoption of electric vehicles (EVs) continues to surge. Increased demand for EVs also requires an infrastructure of charging systems with complex standards and regulations.

European and international EV charging requirements

EV Supply Equipment manufacturers are navigating a measurement landscape that continues to develop across national, European and international markets. With the MID evolving to address EV Supply Equipment and international requirements progressing through OIML, decisions made during product development today can have a direct impact on future compliance and market access.

Why Test and Certify EV Charging Equipment?

Ensure electrical safety of users, equipment and infrastructure
Verify that your products comply with the standards
Evaluate the conformance and interoperability of your products
Ensure electromagnetic compatibility of your charging solutions
Allow you to market your products across multiple markets worldwide

Our EV Supply Equipment Testing & Evaluation Services

NMi provides independent testing, evaluation and conformity assessment support for AC and DC EV charging systems, covering the measurement system, electricity meter, software and applicable legal metrology requirements.

Accessing the German EV Charging Market

For charging stations used for billing in Germany, conformity with German legal metrology requirements (MessEG and MessEV) is required. As a Notified Body for MessEG & MessEV, NMi can support manufacturers through the conformity assessment process for AC and DC EV charging systems.

Our technical scope includes REA 6A / PTB-A 50.7 and VDE-AR-E 2418-3-100, alongside applicable requirements for AC and DC electricity meters.

NMi also actively contributes to OIML, WELMEC, IEC and CENELEC, connecting conformity assessment expertise with the evolving European and international EV charging measurement landscape.
