MID meter

A MID meter is an energy meter placed on the EU market under the Measuring Instruments Directive framework for regulated measurement tasks. The MID sets essential requirements and conformity-assessment routes for covered measuring instruments. Directive (EU) 2026/706 amended the MID to add harmonised measurement rules for electric vehicle charging and hydrogen refuelling stations. That change means charger metrology should be assessed against the current amended legislation rather than older guidance alone. A MID-compliant meter is one part of a charging-billing system. National legal-metrology rules can add requirements for how measurement data is displayed, secured or verified.
