Information
Definition
Energy measurement records the amount of electrical energy delivered, consumed or exported, usually in kilowatt-hours. It is normally assessed alongside measurement accuracy, payment records, tariffs, transaction data and legal metrology requirements.
Why it matters
Accurate measurement supports billing, reporting, reimbursement, fleet accounting and regulatory compliance where charging is paid or reconciled. For UK users, it affects tariff accuracy, payment transparency, customer trust and whether the charging record is suitable for commercial use.

The Measuring Instruments Directive (MID) is the EU framework for placing regulated measuring instruments on the market, including active electrical energy meters used for trade. In EV charging it is relevant to EU market billing, kWh measurement and legal metrology requirements.
MIR
The Measuring Instruments Regulations 2016 (MIR) are the UK regulations covering legally controlled measuring instruments, including active electrical energy meters used for trade. In EV charging they are relevant where measured kWh values are used to calculate charges, payments or rewards.
Eichrecht
Eichrecht Compliant
Eichrecht is German calibration and measurement law affecting how EV charging energy measurements, billing records and customer-facing transaction data are verified. It is mainly relevant to European market compliance rather than UK-only installations.
