Design and implementation of multi-protocol EV charging management cloud platform system

In order to meet the growing demand for the construction and management of electric vehicle charging facilities, a multi-protocol charging pile management cloud platform system is designed and implemented to realize the functions of remote monitoring and management of charging piles, fault diagnosis and statistical analysis. The system aims to provide an efficient and reliable way to manage the charging pile, and realize the real-time communication between the charging pile and the cloud platform through MQTT protocol to ensure the timeliness and reliability of data transmission. At the same time, the HTTP protocol provides a user interface and management interface, which is convenient for users and administrators to manage and monitor the charging pile. First, it analyzes the principle of MQTT protocol and REST API based on HTTP to provide technical support for data upload. Secondly, the design of various functional modules, database, JSON format transmission format and other aspects of the cloud platform, to achieve remote monitoring of charging piles, data analysis and other functions. Finally, the feasibility and stability of the system are verified by experiments and tests with MQTTX tool.
