Description

[0001] technical field [0002] The invention belongs to the field of electric vehicle communication, and in particular relates to a debugging-free composite communication device and method for an electric vehicle charging station. Background technique [0003] At present, in electric vehicle charging stations, there are different types of chargers and charging pile equipment from various manufacturers. Equipment from different manufacturers, or even different equipment from the same manufacturer, use different communication interfaces and communication protocols due to the limitations of development background, operating experience and technical level. It is difficult to achieve seamless integration and interoperability, and additional hardware and software are required. To realize the interconnection, the on-site wiring is complicated, and the interface protocols of each system are inconsistent, which affects the reliability, openness and scalability of the system.

AI Technical Summary

Problems solved by technology

[0007] Chinese patent 201110298433.6 discloses a protocol conversion control system and protocol conversion method for power systems. This method is mainly used for video, audio and video conversion, and is not suitable for communication in electric vehicle charging stations.

[0010] 1) It only realizes the conversion from different protocols to one protocol, and cannot be flexibly used in different communication occasions;

[0011] 2) Only for the conversion of the communication protocol, the automatic modeling and description of the device information cannot be realized. At the same time, when the device is connected to the network, it still needs to be set on the server side to achieve seamless integration;

[0012] 3) The communication method still chooses the traditional communication method, failing to take into account the influence and interference of the complex electromagnetic environment in the charging station on communication;

[0013] 4) Only the conversion of communication is considered, and the unified planning and processing of the equipment information model is not carried out
