An EV charging meter is a measuring device integrated into an EV charger and serves an important function to measure and calculate the electric power, or kWh, consumed by the electric vehicle. To ensures accurate, revenue-grade billing, the meter must comply with regional regulatory frameworks such as the Measurement Instrument Directive from the European Union with a rated accuracy of IEC 62053-41:2021 Class 0.5 and EN50470-4 Class C to be complaint.
Supporting a wide voltage measurement range between 0 to 1000V, the AcuDC 300 delivers on 0.1% revenue-grade accuracy for electric charging billing applications between 60V to 1000V. Ideal for dedicated EV fast charging station infrastructures.
AcuDC 300 is MID certified for regulatory compliance within the international markets. In compliance with IEC 62053-41:2021 Class 0.5 and EN50470-4 Class C, the EV charging meter meets or exceeds rigorous accuracy, environmental, and safety testing requirements in accordance to the MID framework. It provides a reliable performance standard, ideal for revenue-grade billing applications.
AcuDC 300 features cable loss compensation to achieve accurate billing data. The material, length, and width of the charging cable can result in energy loss during the EV charging process. Energy received by the EV may be lower than the amount delivered from the charger due to its natural resistance from the cable. Cable loss compensation factors the power loss and voltage drop caused by the resistance to ensure customers are only charged for the energy received.
OCMF (Open Charge Metering Format) is a widely used data format developed for exchanging data between EV charging infrastructures and billing systems, promoting transparency and interoperability across the industry. AcuDC 300 supports the OCMF format to ensure standardized communication between devices.
AcuDC 300 features a two-tier metrology security system to ensure data integrity. An electronic seal which can be enabled and disabled by toggling the switch on the meter. Certain settings are locked and cannot be modified when the seal is on. The seal switch is enclosed under a protective front casing and secured with two seal tabs. Anti-tampering seals can be used to prevent unauthorized tampering.
The AcuDC 300 includes 3 data loggers and 1 trend logger, and each can be programmed independently to record different real-time metering data and energy usage parameters. The logs are timestamped and stored in a non-volatile memory for data analysis.

AcuDC 300 supports voltage measurement from 0 to 1000VDC and current measurement from -650A to +650A.
The electronic seal can be enabled or disabled by toggling the switch highlighted below. Ensure the meter is powered off before switching the seal, and power the meter back on for the change to take effect.
When the seal is enabled, certain settings will be locked and cannot be configured.
Cable loss compensation can be configured via the meter display or the Acuview 2 software. The cable resistance can be set between 0 and 6.5535Ω. Please refer to the user manual for details.
The AcuDC 300 meter does not come with a power supply and must be purchased separately. Accuenergy recommends ordering the AcuLink-RIK-PSU power supply unit.
