Now the new energy vehicles have become more popular, and the charging pile is naturally the same. The development of the two is closely linked. With the development trend of large cities, the network topology provides a structure with coordination and scalability, Electric vehicle charging pile We are also making great efforts to build. Let's get to know.

(1) Credibility of communication - the communication system shall withstand the impact of extreme natural environment and strong electromagnetic radiation or noise for a long time, and maintain smooth communication.

(2) Capital construction cost - under the premise of considering credibility, comprehensively consider capital construction cost and long-term application and maintenance cost.

(3) Bidirectional communication - not only the submission of data volume, but also the issuance of control volume.

(4) Data and information transmission speed of multi business processes - With the continuous improvement of terminal equipment freight volume, the intermediate communication between domain name and sub station, and between sub station and terminal equipment has increasingly high requirements for data and information transmission speed of multi business processes.

(5) Coordination ability and scalability of communication - because the automobile charging pile (plug) has the characteristics of multiple reference points, wide range and decentralization, it is required to select standard communication protocols. With the development trend of "ALLIP" Internet technology and the continuous improvement of power engineering business processes, it is necessary to consider the load bearing of business processes based on IP, In addition, the regulations are conducive to the construction, adjustment, operation and maintenance of installation works
