Charging in legal compliance: regulations and your rights as a driver
German metrology law also applies to charging columns since the revision. For operators this means regular inspections and certified meters. But: what does it concretely mean for you as an end user at the charging point? We explain the key points in an understandable way.
Metrology law for operators
Public and workplace charging columns with paid use have been legally compliant since 2023 — meaning the electricity measured must be metrologically exact. All public columns were retrofitted by the end of 2024. The operator is obliged to:
- install sealed, certified electricity meters
- carry out regular calibrations by accredited testing bodies (every 4–6 years)
- provide verifiable documentation of the measurement values
Your rights as a driver
Concretely, this means for you at the charging point: the displayed kWh value matches the electricity actually delivered. The billing on your invoice must be traceable — including the price per kWh, any possible waiting and parking fees as well as the entire charging time.
What happens in case of violations?
If a column is no longer calibrated, it must be taken out of service. Concretely: you may no longer charge at this station until a calibration has taken place. Operators face high fines and the withdrawal of the permit for paid electricity supply.
What historical developments have there been?
- Before 2023: many private and quasi-public stations were not required to be calibrated — electricity measurement was optional.
- Since Jan. 2023: charging columns at paid charging points must be equipped with calibrated meters (§15 EichG).
- Retrofit deadline until the end of 2024: existing stations were subject to a transition period for the conversion.
- From January 2025: full implementation of all obligations — new columns must be delivered from the factory in legal compliance.
Tip: check the calibration first
Look for the official calibration logo or seal on the charging column. This lets you know that the displayed kWh reading is correct and that your billing is transparently traceable.
