Why choose high-precision DC energy meters to improve the performance of electric vehicle charging piles?- Zhejiang Yongtailong Electronic Co., Ltd

Main application scenarios
1. DC fast charging piles
In DC fast charging mode, the charging pile directly provides DC power to the electric vehicle battery, avoiding the energy loss of the vehicle's internal inverter. At this time, the DC energy meter can monitor the DC voltage, current and power consumption in real time to ensure charging efficiency and billing accuracy.
2. Distributed charging station monitoring
In large charging stations, operators need to centrally manage multiple charging piles. Through the communication interface of the DC energy meter (such as Modbus, RS485, etc.), the data of each charging pile can be integrated into the background system for remote monitoring and troubleshooting.
3. Protocol docking between vehicles and charging piles
Modern electric vehicles use protocols such as OCPP for energy transmission and data interaction. DC energy meters can provide high-precision real-time energy data to ensure accurate communication between vehicles and charging piles.

Key advantages of DC energy meters
1. High-precision metering
In charging billing scenarios, metering accuracy directly affects user trust and reasonableness of charges. YTL's DC energy meter uses advanced current sampling technology and high-precision analog-to-digital converters to ensure that the measurement error range is ±0.5% under high voltage and high current environments.
2. Low power design
Charging pile equipment needs to operate stably for a long time. YTL's DC energy meter uses a low-power chip design to reduce the overall energy consumption of the equipment and extend the system's operating life. It is particularly suitable for scenarios with solar power supply or high grid pressure.
3. Real-time data communication and storage
DC energy meters are equipped with a variety of communication interfaces (RS485, CAN, etc.) to support real-time data upload to the charging pile management platform. In addition, historical data can be recorded to provide strong support for charging behavior analysis, equipment maintenance and energy consumption optimization.
4. Reliability and durability
YTL's DC energy meter has been rigorously tested and can work normally in the temperature range of -40℃ to 85℃. It has good waterproof and dustproof performance and can adapt to complex outdoor charging pile environments.
5. Modular design
