Abstract: With the popularity of electric vehicles, battery swap stations have become an important infrastructure for battery energy replenishment. In order to improve operation and maintenance efficiency and equipment stability, cloud computing technology is gradually being applied to the intelligent management and automated operation and maintenance of swap stations. This paper explores the application of cloud computing in the intelligent operation and maintenance service platform of battery swap stations, analyzes the requirements for real-time monitoring, automated operation and maintenance, data processing, elastic expansion and efficient collaboration, designs a cloud computing-based architecture and core functions, and discusses data security and privacy protection strategies in detail.
