Introduced the characteristics of monitoring for the electric vehicle charging facilities, analysis of the model structure and the plug-in structure. Determined software architecture of platform and plugin for charging facilities monitoring configuration software. Elaborated on the interface design, workflow and application examples of plug-in in the configuration software. Engineering practice has proved that the configuration software through the use of plug-in technology to improve the degree of modular, a powerful expansion function, plug-and-play and to meet the needs of different users.
