DC energy meters for accurate monitoring in fast EV chargers

Mouser Electronics, Inc. now stocks the DCM1 DC energy meters with Ethernet from Carlo Gavazzi. The DCM1 Series is created to meet the growing demand for DC metering requirements in fast, ultra-fast, and hyper-fast chargers for EVs. The DC energy meters, which allow for accurate monitoring and billing in EV charging stations and battery energy storage systems, can also provide power analysis capabilities for DC systems in microgrids and other energy-efficient applications.

The DC energy meters with Ethernet are direct-connection devices for DC systems up to 1000V and 600A. The energy meters display information about the specific charging session while receiving and processing start/stop session commands. The meters feature a transducer for voltage and current connection and a display unit with RS485 Modbus RTU and Ethernet Modbus TCP communication ports. A cable linked to the transducer connects the two components for quick and easy installation. The meters are installed on the DC side, compatible with most DC chargers, and support horizontal and vertical mounting. A cable loss management function ensures the meters only consider energy supplied to the vehicle and remove losses caused by cable resistance.

The DCM1 DC energy meters offer automatic alerts for safe and reliable performance in case of overtemperature, overcurrent, or overvoltage. Secure and signed data transmission to the controller guarantees data authenticity, and the display updates automatically to show information relevant to the charging session. The DCM1 energy meters are tamper-proof with sealable measuring inputs and communication ports. The DCM1 Series is CE, cURus, MID, LNE (pending), Eichrecht, and CTEP compliant.
