Technical information about DCBM energy meter

Smart and compact, the Direct Current Billing Meter (DCBM) gives charging station providers the ability to deliver a ‘gas station’ like experience, using an LCD display to show real time measurements, energy, alarms and legal data.

An excellent solution for retrofit and new DC fast charging stations from 25 to 400 kW, the DCBM uses industry standard data protocols. The results are secured communication, authentic billing, easy connectivity to Cloud services and a faster certification process in compliance with metrology regulations.
