Understanding Safety Risk Warning Technologies for Lithium-Ion Battery Energy Storage Power Stations from an Engineering Perspective

As an important part of the new power system, the safety of lithium-ion battery energy storage power station may pose a potential threat to personnel, environment and equipment. At present, there are a variety of safe operation risk early warning technologies, but the concepts of “early warning” and “alarm” are often confused and difficult to distinguish. In this paper, firstly, the connotation of safety protection of lithium-ion battery energy storage power station is deeply analyzed, the development map of safe operation risk is constructed, and the characteristic signals and technical measures at each stage are determined. Then, different early warning technologies are compared, and the adaptability of early warning technology based on battery external signal and operation data is analyzed. Finally, the application of early warning technology in engineering is counted, and based on the risk early warning technology developed by the team, the occurrence probability of common risks is analyzed to provide reference for research and application.
