Netherlands-based inepro Metering has introduced its PRO380-Eichrecht energy meter, designed to comply with a German regulation requiring all public EV charging stations to have certified, calibrated electricity meters.
The German calibration law, commonly known as Eichrecht, applies to all measuring devices. By including EV charging station meters, the regulation aims to ensure that EV drivers are only billed for the energy they consume. It mandates transparent metering, clear billing and secure data processing.


Charging stations must display real-time kWh readings or provide visual access to the meter. They must collect signed meter data that protects each session and can be verified through public key systems.
The PRO380-Eichrecht meter records accurate signed energy measurements to ensure correct billing, supports OCMF 1.3.1, digital signatures and tamper-proof data logging. It enables independent consumption verification via third-party apps such as S.A.F.E. and integrates with systems using the RS485 Modbus RTU protocol.
An operating temperature range of -40° C to 70° C enables the meter to operate in a range of demanding environments.
