Lithium Battery Energy Storage Safety Risk Monitoring and Early Warning

This document addresses the critical safety issues of lithium battery energy storage power stations, which have become increasingly prominent due to frequent fire incidents globally. It reviews relevant policies and standards, including the Guiding Opinions on Accelerating the Development of New Energy Storage and the new national standard GB/T 42288-2022, which mandate enhanced monitoring and early warning capabilities. The document identifies deficiencies in current safety prevention systems, such as limited BMS computing power, lack of system-level fault identification, and reactive maintenance practices. It proposes leveraging big data technology for online status assessment and proactive early warning to reduce accident risks. Key technologies include battery status assessment, fault early warning, and an intelligent operation and maintenance system combining cloud-based management with edge computing. The system aims to optimize energy storage power station strategies, promptly identify degraded units, and prevent thermal runaway, thereby improving overall safety and reliability.
