Accuenergy launches AcuDC 300 EV charging meter for high-precision DC energy measurement

Accuenergy has introduced the AcuDC 300 EV Charging Meter, a revenue-grade DC energy meter designed specifically to serve the expanding electric vehicle fast-charging infrastructure market. The device provides 0.1 percent measurement accuracy across an input voltage range from 60 to 1000 VDC and it is MID-certified, meeting IEC 62053-41:2021 Class 0.5 and EN 50470-4 Class C standards for legal billing applications internationally. Engineered to capture precise, reliable measurements in bidirectional EV charging setups, the AcuDC 300 supports vehicle-to-grid (V2G) and other advanced charging applications. To enhance billing accuracy, it includes cable-loss compensation, anti-tamper protection with both electronic and physical seals and built-in data logging with non-volatile memory to ensure data retention during outages. Additionally, the AcuDC 300 offers digitally signed OCMF (Open Charge Metering Format) output to enable seamless data exchange and interoperability with EV infrastructure backend systems. “The EV charging landscape is evolving quickly, and operators need tools that meet both technical performance and regulatory requirements,” said Ryan Manbahal, Product Manager at Accuenergy. “The AcuDC 300 was designed to address that exact need, providing precise DC measurement, secure data integrity and compatibility with modern EV fast charging systems.” Communication-wise, the meter integrates Modbus RTU over RS485 and Modbus TCP/IP over Ethernet, ensuring compatibility across SCADA, EMS and energy billing platforms. With its DIN rail–mountable design, the AcuDC 300 provides easy integration and installation flexibility for EV charging infrastructure applications ranging from standard to ultra-fast chargers. As electric vehicles increasingly transition to higher voltages, accurate metering at levels up to 1000 VDC becomes necessary for reliable operational management and compliance. Specifically developed to address these needs, Accuenergy’s AcuDC 300 targets DC fast-charging stations for electric vehicles, offering enhanced operational insight with verified data management capabilities.
