In the process of charging electric vehicles, DC fast charging technology is the mainstream. The charging energy is directly measured by the DC energy meter, and its accuracy directly affects the fairness of charging fee calculation and user experience. Compared with traditional AC energy meters, DC energy meters are specially optimized for the application scenarios of charging stations, and can ensure high-precision metering in complex power environments.
1. High-precision sensing technology
The DC energy meter uses advanced Hall sensor or shunt technology to accurately collect current and voltage signals with an accuracy of ±0.5% or even higher. It can also maintain good adaptability to current fluctuations of high-power charging equipment (such as 350kW fast charging piles).
2. Real-time data sampling and algorithm optimization
Through high-frequency real-time sampling (such as up to thousands of times per second), the DC energy meter can capture small changes in the flow of electric energy. With the built-in intelligent metering algorithm, the dynamic accuracy of the metering data is guaranteed to avoid metering errors caused by fluctuations.
3. Temperature compensation technology
During fast charging, the device may affect the measurement accuracy due to ambient temperature or load heating. The DC energy meter integrates temperature compensation function, which can correct the error caused by temperature change in real time, so as to ensure consistent measurement results in cold or hot environment.
4. High power measurement capability
In response to the fast charging needs of electric vehicles, the DC energy meter supports a wide power range from tens of kilowatts to hundreds of kilowatts, and can accurately record the complete charging process from startup to disconnection, eliminating the phenomenon of "jumping meter" or "missing meter".
