MID rail type DC energy meter with European standard DC charging pile matching

With the acceleration of global energy transition, Chinacharging pileEnterprises are turning their attention to overseas markets, especially the European market. However, exporting to Europe is not an easy task, as companies go through a series of strict compliance measurescertificationSystem. Among them, CE certification is a basic requirement, while for those who possesselectricity meteringThe EU Measurement Instrument Directive (MID) is a key threshold for functional charging stations.

Using MID certified energy meters as the core energy metering component of charging stations not only directly meets EU regulatory requirements, but also significantly shortens project cycles and reduces development costs, making it a better choice for Chinese charging station companies to go global to Europe.
