Integrated DC energy meter for heavy-duty truck charging station

Integrated DC energy meter for heavy-duty truck charging stationDJSF1352-D-600, is a product developed specifically for DC metering scenarios such as charging stations. It adopts an integrated design of a splitter and an energy meter, and has the characteristics of high metering accuracy, small size, convenient wiring, strong communication compatibility, and rich functions.

Measurement accuracy requirements

The measurement accuracy of low-power DC charging stations is directly related to the interests of consumers and the cost accounting of operators. According to relevant standards, such as JJG 1149-2022 "Verification Regulations for Off board Chargers of Electric Vehicles", the accuracy level of DC charging piles is divided into level 1 and level 2.

stability requirements

The stability of DC energy metering is crucial for long-term reliable billing. Low power DC charging stations may be affected by factors such as different environmental temperatures, humidity, and power grid fluctuations. To ensure stability, the charging station needs to be equipped with high-quality metering modules and have good temperature compensation and anti-interference capabilities. It can ensure metering stability within the environmental temperature range of -20 ℃ to+50 ℃, ensuring long-term stability and accurate billing.

Data recording and transmission requirements

To achieve refined operational management, low-power DC charging stations need to have complete data recording and transmission functions. In terms of data recording, it is necessary to record in detail the start time, end time, charging amount, charging cost, and other information of each charging. The operator can monitor the operation status and energy measurement of charging piles in real time through the platform, timely discover and handle problems, and improve operational efficiency and service quality.

Compatibility requirements with charging facilities

With the development of new energy vehicle technology, there are differences in the charging needs of different brands and models of vehicles, which requires good compatibility in the energy metering of low-power DC charging piles. On the one hand, the metering system should be able to adapt to different ranges of vehicle charging voltage and current changes. On the other hand, it needs to be compatible with different charging protocols.
