MID is an acronym that refers to the Measuring Instruments Directive. The Directive is the requirements for metering devices in Europe. This includes electrical meters, gas meters, water meters, weighing systems, and so forth. The purpose of this directive is to give more protection to the consumer, safeguarding the proper measurement of your consumption.
MID certification means that the device is certified to have highly sensitive and discriminate capabilities of measuring, whether constantly or intermittently used. This certification will be valid for a certain number of years, depending on the local requirements. Germany, for instance, requires meters capabilities are valid for eight years.
The Easee chargers which are MID-compliant have special displays on the side of the charger for showing the measured cumulative kilowatt-hours (kWh) used by the charger. The MID compliance guarantees the validity of the reading.
