Introducing DC Electricity Meter for EV Charging Stations

Introducing DC Electricity Meter for EV Charging Stations

As electric vehicle (EV) adoption continues to grow, so does the demand for accurate, reliable, and secure energy monitoring systems within charging stations. At Eastron Europe, we are excited to announce the launch of our new range of advanced DC meters – the DCM6-650DCM6-200,  designed specifically for seamless integration into EV charging stations.

These innovative EV charger meters are crafted to meet the evolving needs of the electric mobility sector, offering a robust solution for monitoring and recording energy usage with exceptional precision. Below, we explore the key features of these meters and their significance in enhancing the EV charging experience.

A New Era in EV Charging Energy Monitoring

Both the DCM6-650 and DCM6-200 meters are built for accurate and secure energy measurement, making them the ideal choice for EV charging infrastructure. Their cutting-edge technology ensures that energy data is logged with timestamps and digital signatures, aligning with legal requirements for billing. This makes it easier to provide transparent and verified records for energy usage, which is essential for ensuring customer trust and regulatory compliance. 

These EV meters connect seamlessly to the EV station controller via RS485, ensuring that all signed datasets are transmitted securely and maintain their integrity throughout the process. By offering such a secure transmission protocol, Eastron Europe’s meters ensure that users and service providers can count on reliable data that is tamper-proof.

What is a DC Electricity Meter? 

A DC electricity meters, like Eastron Europe’s DCM6-650DCM6-200, are designed for direct installation in electric vehicle (EV) charging stations. They measure the flow of direct current. Unlike its alternating current (AC) counterpart, a DC meter measures current and voltage in circuits where electricity flows in a constant direction, typically used in solar energy systems, battery storage, and electric vehicle (EV) charging stations. A DC electricity meter in EV charging stations ensures that energy usage is accurately measured, monitored, and billed. These meters form an essential part of the growing DC grid ecosystem, which supports renewable energy sources and electric mobility. 

 

OCMF 1.2.0 Compliance: Broad Compatibility for Future-Proof Solutions

One of the standout features of the DCM6-650 and DCM6-200 is their compliance with the Open Charge Metering Format (OCMF) 1.2.0. This ensures compatibility with a wide range of devices, offering flexibility and future-proofing for those looking to integrate the meters into existing or upcoming EV infrastructure. With OCMF compliance, the meters can seamlessly interface with various systems, reducing installation complexity and enhancing overall operational efficiency.

Built for Extreme Conditions

The DCM6-650 and DCM6-200 are designed to perform under extreme temperature conditions, with an operating range from -40°C to +80°C. This durability makes them suitable for diverse environments, whether they are installed in freezing cold climates or scorching hot regions. This flexibility ensures that the meters for EV charging station will remain accurate and reliable no matter where they are installed.

Comprehensive Data Logging and Performance Analysis

Both meters offer extensive data storage capabilities, with the ability to store over 225,000 transaction records and more than 3,000 event logs. This makes it possible to keep detailed records of energy consumption, charging sessions, and other key events, all of which can be used for audit trails, performance analysis, and reporting.

The stored data can also be visualised through a transparency software that allows customers to verify invoiced processes. This application visualises key charging metrics such as energy consumption and signature verification, giving users a clear and reliable overview of each charging event. This ensures precise and compliant billing while allowing users to have full transparency of their energy usage.

Advanced Features for Accuracy and Efficiency

Both the DCM6-650 and DCM6-200 come equipped with a cable loss calculation function, which enhances the accuracy of energy measurement. This feature ensures that the system accounts for any energy lost during transmission, providing a more precise reading of actual energy usage. For charging stations that need to operate with maximum efficiency, this is a crucial feature for accurate billing and energy management.

Applications in EV Charging Stations

The DCM6-650 and DCM6-200 are designed for use in a wide range of EV charging station applications, from small residential setups to large-scale public or commercial charging hubs. Their robust design, secure data transmission, and extensive storage capabilities make them ideal for ensuring accurate, reliable, and transparent billing for users.

With these meters, charging station operators can monitor energy consumption in real-time, ensuring that energy usage is accounted for, and that billing is accurate and compliant. The bi-directional measurement feature also makes these meters perfect for energy management in systems where both energy import and export are involved, such as solar-powered charging stations.

Additional Accessory for DC Meter

The DCM-D is an external display module that serves as an additional accessory to the DCM6-200 and DCM6-650 DC meters, offering enhanced convenience and flexibility for energy monitoring. This Eichrecht certified device features a remote display, providing a user-friendly interface to view the meter’s values. It connects to the meter via an easy-to-install RJ45 plug-in connection, with an additional RJ12 data cable for flexible installation. The display is Bluetooth enabled and also offers an optional TCP Ethernet port for advanced connectivity. Designed with a backlit dot matrix display, the DCM-D includes two front-panel buttons for quick data checking and configuration. Billing-relevant information is also easily accessible, ensuring transparent and compliant energy usage tracking.
