Eichrecht

Eichrecht is the German legal-metrology framework governing how measured quantities used for billing must be measured and presented. For public EV charging, it is concerned with ensuring that the energy measurement and resulting bill can be checked and trusted. Germany's national metrology institute, PTB, states that calibration law at public charging stations is intended to ensure correct measurement and billing. Eichrecht compliance involves more than fitting an accurate energy meter. The complete measurement and billing chain can matter, so product requirements should be checked against the current German metrology rules and applicable certification approach.
