This paper designs a charging station operation management system based on integrated energy optimization in order to meet the diversified charging needs of electric vehicles. This system adopts an ActiveMQ message bus to realize interconnection between stations. At the same time, it combines multiple payment methods and WEB technology to improve system operation and maintenance management capabilities. On the basis of the original credit card charging and scanning code charging, using vehicle VIN identification technology, the plug and charge function is added to enrich the charging method. The system expands the access management function of the photovoltaic power generation system and energy storage system, achieves unified energy allocation of integrated power storage and storage power station, and maximizes the consumption of photovoltaic power generation to reduce the charging cost of electric vehicles. It has been verified through engineering applications that the system can not only meet the cross-station charging of special vehicles and realize the charging operation of social vehicles, but also help the higher-level operating platform to manage the equipment in layers and hierarchies.
