en.Wedoany.com Reported - With the rapid adoption of Vehicle Industry" target="_blank">new energy vehicles, DC fast charging piles have become the core replenishment infrastructure in cities, highways, industrial parks, and stations. Under high-power charging, multi-pile centralized operation, and complex outdoor conditions, precise metering, stable monitoring, and efficient networking of DC power supply have become essential requirements. Traditional meters commonly suffer from issues such as large metering deviations, low integration, unstable communication, and poor adaptability to working conditions, leading to billing disputes, inefficient operation and maintenance, and high deployment costs, making it difficult to meet the large-scale, standardized, and intelligent operation needs of DC charging piles.

To address these challenges, CHINT Instruments has developed two differentiated DC energy meter solutions: the iDCM4/DJZU666 split-type DC meter, with CPA certification, is the preferred choice for standardized operation of DC charging piles in China; the iDCM5/DJZU666 integrated DC meter, holding MID overseas certification, is suitable for exported integrated DC equipment. Both share a high-precision metering core, offering accurate billing, remote operation and maintenance, and stable performance across a wide temperature range, allowing flexible selection based on project layout and market region.

01 Product Introduction

iDCM4/DJZU666 Series Split-Type DC Energy Meter—Preferred Solution for DC Metering in China

The iDCM4/DJZU666 series split-type DC energy meter is a new generation intelligent metering instrument designed for new energy DC power distribution scenarios, tailored for DC charging piles, communication base stations, data centers, and photovoltaic systems in China. With advantages of high precision, high reliability, and easy networking, it comprehensively addresses pain points such as inaccurate metering, difficult integration, weak communication, and unstable working conditions in DC charging piles, supporting safe operation, accurate billing, and efficient management of charging stations, making it the preferred metering and monitoring solution for DC charging scenarios in China.

iDCM5/DJZU666 Series Integrated DC Energy Meter—Preferred Solution for Overseas DC Metering

The iDCM5/DJZU666 integrated DC smart energy meter is a new generation product developed for DC metering scenarios such as charging piles. It features an integrated design of shunt and meter, offering high metering accuracy, compact size, convenient wiring, strong communication compatibility, and rich functionality. It enables overall sealing of the shunt and meter, making it the preferred metering product in the DC charging pile industry.

02 Differentiated Unique Advantages of the Two DC Energy Meter Solutions

Different certification types for compliance assurance: Both provide legal metering basis for operators, but due to differences in application scenarios, the certification types vary: The iDCM4/DJZU666 series split-type DC energy meter has CPA certification, meeting China's domestic metering instrument access requirements; the iDCM5/DJZU666 integrated DC smart energy meter has MID certification, meeting overseas metering instrument access requirements.

Different meter structure types: The iDCM4/DJZU666 series split-type DC energy meter adopts a split structure design, using the mainstream "shunt and meter separation" approach. The meter supports dual-channel measurement, is not limited by wiring position or cabinet space, has low size requirements, and perfectly fits the compact layout inside charging piles. The iDCM5/DJZU666 series adopts an integrated structure, with a compact design reducing failure points, adapting to extreme environments from -40°C to 70°C, ensuring long-term stable operation of the equipment.

03 Common Features of Both DC Energy Meter Solutions

Accurate metering, reliable data: Both are optimized for high-power dynamic charging scenarios of DC charging piles, unaffected by current fluctuations, providing precise and stable metering data to avoid billing disputes and ensure the credibility of station operations.

Easy installation and networking, cost reduction and efficiency improvement: Standard RS485 communication interface allows direct networking with charging controllers and station management systems, ensuring stable data transmission and low latency, effectively supporting remote monitoring, data collection, and intelligent operation and maintenance.

During the large-scale deployment of new energy DC projects, every link—metering compliance, wiring and installation, environmental adaptation, and remote operation and maintenance—directly impacts station operational efficiency. CHINT Instruments simultaneously launches split-type and integrated DC energy meters, meeting domestic regulatory requirements in China while breaking through overseas market certification barriers, using stable and reliable metering hardware to avoid billing disputes and reduce long-term operation and maintenance costs.
