WHAT TYPES OF METERS EXIST?
Digital Meter
The simplest method of measuring current in charging systems is digital measurement. It is used in residential settings and enables reliable monitoring of consumption. The measurement accuracy is equivalent to that of MID-certified products, but it is not calibrated.

MID Meter
Charging systems equipped with MID meters can be used worldwide for billing accurate to the kilowatt-hour. They are calibrated by a testing agency and are generally not readable from the outside. According to the MID certification, the service life of electronic electricity meters in Germany is 8 years.

Legally Compliant Meter

In addition to MID certification, the charging system has undergone a metrology inspection by a German regulatory authority (PTB). During this inspection, the entire charging system was tested to ensure that the meter readings cannot be tampered with. Publicly accessible chargers must comply with metrology regulations to enable billing of charging sessions accurate to the kilowatt-hour.

Do you need MID-compliant or metrology-compliant chargers?
Whether you need MID-compliant or metrology-compliant chargers depends on the type of charging process you use.
- The Measuring Instruments Directive (MID) is an EU regulation that governs measuring instruments and control systems for energy and liquids. MID-certified devices are required for use in commercial and industrial applications.
- Calibration-compliant chargers, on the other hand, refer to chargers that meet the requirements of calibration law. This means they ensure accurate measurement of energy consumption and proper billing.
What are the benefits of calibration-compliant charging?
- Legal certainty: By using chargers that comply with calibration regulations, you can be sure that you meet all legal requirements and do not have to worry about any legal consequences.
- Avoiding Conflicts: Since the billed consumption matches the actual energy used, there is no risk of disputes with employees or third parties.
- Cost Savings: By using chargers that comply with calibration regulations, you can avoid incurring additional costs in the future for retrofitting or replacing the chargers.
