- CE, cURus MID, LNE, Eichrecht certified Charging session management and OCMF file generation.
EV charging applications today are mainly based on fast, ultra-fast, and hyper-fast chargers, and Carlo Gavazzi with its DCT1 energy transducer, has given the first and most suitable response to this need. A very flexible, simple, compact, and easy-tointegrate solution for energy measurement in DC fast chargers: with the DCT1 we are also able to provide a metering system that also contributes to the charger certification in the US (CTEP/NTEP) thanks to its resolution of 0.1 Wh and of course the cURus certification.
The natural process of evolution leads to the release of the DCM1, which includes a remote display, that can be shown from outside of the charger or in any case be installed far from the 1000 VDC segregated part of the charger, where easy access is not possible, to read variables or scroll display pages.
“The DCM1 is a meter which can also show information about the specific charging session, being able to receive and process start/stop session commands, the official time and date used by the controller and other options,” Andrea Bernardi, International Product Manager states. “It is also equipped with an Ethernet port, so energy measurement information can be transmitted to the charger with Modbus RTU or Modbus TCP protocols. With the launch of the DCM1energy meter we aim to consolidate our presence and position ourselves at the forefront of energy measurement also in DC fast charger applications.”
Developed in our Competence Center in Italy, the DCM1 is designed to provide an accurate monitoring system for certified fiscal billing in EV charging stations and battery energy storage systems, while providing power analysis capabilities to DC distribution systems in Energy efficiency applications.
