Accurate billing is key for charging stations – the DJSF1352 DC power meter safeguards charging operations

With the continuous increase in the number of new energy vehicles, DC fast charging piles have become an important part of urban infrastructure. However, behind the rapid deployment of charging piles, a key issue has always been a concern for operators and users: Is every kilowatt-hour of electricity accurately measured? Is every charge settled fairly?

In DC charging piles, the DC energy meter is not only the core basis for billing but also a key node for equipment monitoring and operation management. The DJSF1352 series DC energy meter, with its high accuracy, high reliability, and multi-adaptability, is becoming the standard choice for charging pile metering.

Inaccurate measurement

In the operation of charging stations, the consequences of inaccurate metering go far beyond a simple "slightly different electricity bill":

Frequent user complaints: Significant discrepancies between billing and vehicle display directly impact user trust;

Constant settlement disputes: Disputes arise between operators and charging station owners over electricity bill revenue sharing;

Increased regulatory risks: Compliance requirements such as domestic CPA certification and European MID certification are becoming increasingly stringent; if metering equipment fails to meet standards, the entire charging station cannot be marketed.

Therefore, choosing a fully certified, accurate, and flexible DC power meter has become a consensus among charging station manufacturers and operators.

Tailor-made for charging pile metering

The DJSF1352 series DC energy meters cover both split and integrated solutions, fully adapting to current mainstream charging pile technologies and meeting diverse needs from ordinary fast charging to megawatt-level supercharging.

1. Complete Certifications, Globally Recognized: Domestic: CPA certification, meeting mandatory verification requirements; Europe: MID certification, complying with charging pile regulations; North America: UL/CTEP certification (some models), facilitating the export of complete charging piles.

2. Stable Accuracy, Bidirectional Metering: Supports 0.5/1 level accuracy, independent metering of forward and reverse energy, suitable for bidirectional charging and discharging scenarios (such as V2G charging piles), reserving space for future operating models.

3. Flexible Adaptability, Covering the Entire Power Range: Integrated Solution (DJSF1352-D Series): Built-in shunt, simple installation, compact size, suitable for 60A–360A conventional fast charging piles; Split Solution (DJSF1352-RN Series): Main unit + external shunt, range expandable up to 1500A, easily covering high-power scenarios such as liquid-cooled supercharging and megawatt flash charging.

4. Dual-Circuit Metering, Supporting Multi-Gun Operation: For dual-gun scenarios on a single charging pile, models such as the DJSF1352-RN-2 support independent metering on both circuits, enabling independent billing and management of both guns, resulting in more flexible operation.

It's also an operations assistant

The DJSF1352 series not only performs electricity metering but also features overvoltage and overcurrent alarms, real-time communication, and line loss compensation. It can seamlessly integrate with charging operation platforms, helping operators to:

Real-time monitor charging pile status and promptly detect anomalies;

Accurately calculate line losses and improve settlement accuracy;

Reduce maintenance costs and improve operational efficiency.

Summarize

As charging technology continues to evolve, current ratings have increased from 60A to 1500A, leading to higher requirements for metering equipment. The DJSF1352 series, with its wide range design, high anti-interference capabilities, and comprehensive certification system, has become a long-term partner of major domestic charging pile manufacturers.

Making every charge precise and reliable; making every unit of electricity trustworthy.
