Architecture Design and Key Technologies of Electric Vehicle Charging Network Operation Service System Based on Cloud Computing

Facing the rapidly growing user group of the EV charging network and the massive data information produced by it, the operational service system which uses the traditional monitoring platform framework has some deficiencies in terms of scalability and flexibility. In this paper, a cloud computing-based EV charging network operation service architecture is proposed, and Infrastructure as a Service layer, Platform as a Service layer, Software as a Service layer under the charging network cloud architecture are designed accordingly. In addition, the key technologies such as RFID label data security access of data acquisition layer, data integration and efficient indexing for multi-tenancy in the data layer, and detection of abnormal behavior of charge pile streaming data based on machine learning in data processing layer are studied, moreover, the corresponding solutions are given.
