Guidance on Measurement and Calibration Laws in the Charging Infrastructure

Numerous requirements under measurement and calibration law must be observed in connection with the installation, operation, and billing of charging infrastructure. The new Q&A guide from the National Charging Infrastructure Coordination Center, operated by NOW GmbH (National Organization for the Transformation of Mobility), provides guidance to manufacturers, operators, and other users.

The questionnaire addresses key issues regarding metrology requirements for charging infrastructure for passenger cars and trucks. For example, it covers the specific requirements for compliance with metrology regulations, the obligations these impose on operators and other users, and how to prepare for future technological developments today.

Johannes Pallasch, Head and Spokesman of the National Charging Infrastructure Control Center: „There is still some uncertainty surrounding measurement and calibration law. We can see this from the many questions we receive from the field. At the same time, the topic is highly relevant for operators and other market participants, because only charging infrastructure that complies with calibration law creates transparency, trust, and legal certainty. With this Q&A guide, we’re providing clear guidance on the matter.”

The Q&A guide is part of the information resources provided by the National Charging Infrastructure Coordination Center, which coordinates and supports the expansion of the charging infrastructure in Germany on behalf of the Federal Ministry of Transportation. It was developed in close collaboration with the Working Group on Measurement and Calibration of the State Calibration Authorities (AGME) as well as with the German National Metrology Institute (PTB), whose expert assessments form the basis for the answers.
