German Calibration law, a.k.a Eichrecht, The German Calibration Law, known as Eichrecht, primarily aims to protect consumers and ensure that billing for charging sessions is transparent and accurate. Under Eichrecht, all public EV charging stations must be equipped with a certified and calibrated electric meter to ensure accuracy and reliability. Charging stations must display prices clearly and provide customers with a receipt that shows the amount of electricity consumed, the price charged, and other relevant details. The electric meter measures the electricity consumed and determines the amount that the EV driver will be charged. All prices are based solely on KWh consumption, not on time-based or flat fees, to ensure clear and easy-to-understand prices for EV charging. Eichrecht requires all public EV charging stations to have a certified and calibrated electric meter to ensure accuracy and reliability. Each charge point must have a visible kWh measurement meter registered and periodically calibrated. EV drivers can quickly confirm the kWh reading via display or actual kWh meter device and verify this on their e-mobility app or web interface, ensuring transparency in billing.
EM118089/90/91 EM519032/33/24 MID approved din rail meter also comply with this German calibration law Eichrecht standard. it makes the kwh measurement easier and more transparent in EV charging ,what's more, they support rs485 communication and bidirectional meter=dual metering for bidirectional ev charger.
