The calibration law “Eichrecht” requires that all components in and outside the charger that are involved in the collection and processing of measured values up to the invoice amount must be trustworthy, or at least that it must be possible to validate the invoice exclusively on the basis of trustworthy components.
Eichrecht Conforming Charging – Six Steps
Calibration compliance means that the measurement records are stored transparently for each individual loading process. According to the Measurement and Calibration Act (MessEG), the Measurement and Verification Ordinance (MessEV) and the Price Indication Ordinance (PAngV), electricity from public charging stations in Germany may only be invoiced according to legal requirements from 1.4.2019.
- The charging process is started via the smartphone or the RFID card.
- Measurement data sets are signed locally stored
- The independent batch point operator receives the signed measurement data records of the loading process
- The eMobility Provider receives the signed measurement data records via an independent roaming platform
- The end-user receives the billing of the signed data Measurement datasets
- The end-user can check the billing for authenticity with the help of the independent, freely accessible transparency software if required
