Construction requirements for charging piles


As an electric vehicle charging pile (peg) on the distribution side of the power grid, the specificity of its structure determines that the automated communication system is characterised by a large number of measured points and dispersed, wide coverage and short communication distance. And with the development of the city, the network topology requires a flexible and expandable structure, therefore, the selection of communication methods for electric vehicle charging pile (peg) should consider the following issues:

(1) Reliability of communication - the communication system should withstand the test of harsh environment and strong electromagnetic interference or noise interference for a long time, and keep the communication smooth.

(2) Construction costs - under the premise of meeting the reliability, comprehensive consideration of construction costs and long-term use and maintenance costs.

(3) Two-way communication - not only to achieve the uploading of information volume, but also to achieve the control volume of the downstream.

(4) Multi-service data transmission rate - with the growing volume of terminal services in the future, the communication between the master station to the sub-station and the sub-station to the terminal requires more and more high data transmission rate for realising multi-service.

(5) Flexibility and expandability of communication - As the charging pile (bolts) has the characteristics of many control points, wide surface and dispersion, it requires the use of standard communication protocols, and with the development of the trend of "ALL IP" network technology and the continuous growth of electric power operations, it is necessary to consider the IP-based business. With the development of "ALL IP" network technology trend and the continuous growth of electric power operation business, it is necessary to consider IP-based service bearing, and at the same time, it is required to facilitate the installation, construction, commissioning, operation and maintenance.
