With the rapid development of electric vehicle charging infrastructure, accurate metering, safe operation, and efficient management of charging piles have become the focus of industry attention. 

Acrel's MID-certified multi-function meters ADL400/ADL200 series seamlessly integrate with charging pile systems, providing operators with a highly efficient "integration-free, quick-to-market" solution.

What is MID certification? Why is it crucial for charging stations?

MID (Measuring Instruments Directive) is a mandatory certification standard for metering equipment in the European Union,applicable to electricity meters, water meters, gas meters, etc. 

Electricity meters with MID certification mean they meet EU regulations in terms of metering accuracy, environmental adaptability, and data reliability, are legally valid, and can be used for trade settlements.
