LEM introduces DC billing meter for EV chargersLEM introduces DC billing meter for EV chargers

LEM, a global specialist in electrical measurement for industrial and automotive applications, has launched its new DC billing meter (DCBM), a compact billing solution for public DC fast chargers. The DCBM has a power measurement range from 25 kW to 600 kW, and is a legally certified meter that provides accurate customer billing. 

LEM’s new DCBM is compliant with Germany’s Eichrecht regulation, which requires that consumers are only charged for the DC power that’s supplied to the battery. Additional standards are being established not only at the European level but also at the international level, as well as in the state of California.

LEM says its DCBM was developed to meet market demands for interoperability and data security. It’s designed to be easily retrofitted to existing chargers, and can provide power at up to 600 A/1,000 V. The DCBM offers Ethernet communications, and supports the HTTPS/REST protocol to allow quick integration and deployment in charging stations.

The DCBM also integrates the signed billing data sets specified by the SAFE OCMF protocol, allowing billing data to be transmitted with a high level of security and providing interoperability for cloud service operators.

Features include:

    • Standardized Direct Current Billing Meter in compliance with VDE-AR-E-2418-3-100  

    • Meter accuracy can be adjusted depending on the charging cable in use

    • LCD shows live measurements, energy, alarms and legal data 

    • Ethernet communication allows quick integration and deployment in charging stations

    • Signed billing data sets offer security and interoperability for cloud service operators
