Dc charging pile meter communication protocol support components
Main component
Concept:
The communication protocol supporting components of a DC charging pile meter refer to the hardware and software components inside the meter for data exchange with external systems (such as charging pile management systems, electric vehicles, etc.). These components ensure that the meter can accurately send and receive data, including key parameters such as power, voltage, and current, according to established communication protocols.
Function:
The main function of communication protocol supporting components is to realize effective communication between DC charging pile meters and external devices. They enable the meter to transmit power data, receive control commands, and work with the charging pile management system for remote monitoring, billing, and diagnostics. These components are essential to ensure that the charging process is intelligent and automated.
Working Principle:
Dc charging pile meters usually support a variety of communication protocols, such as Modbus-RTU, DL/T645-2007 protocol, etc., to adapt to different communication needs. In the process of data transmission, the meter first encapsulates the power data according to a specific protocol, and then sends it out through a communication interface such as RS485 or CAN. The receiver parses the data according to the same protocol, enabling monitoring and control of the meter status. For example, the DLT645-2007 protocol requires that the leading code is added to wake up the receiver when the meter communicates, and all data items are sent low bytes first, then high bytes, and the data field is processed specifically to ensure the accuracy and security of the data.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
