On the one hand, energy storage technology can help solve energy supply problems, improve energy utilization efficiency, and reduce energy consumption, thereby contributing to environmental protection and sustainable development. On the other hand, with the large-scale grid connection of renewable energy and the continuous improvement of the power market, the application scenarios of energy storage technology are also expanding, providing a broad market space for the development of the energy storage industry. At present, the main types of energy storage on the market include physical energy storage and electrochemical energy storage, and electrochemical energy storage is the type of energy storage that has developed rapidly in recent years.

[0003] With the large-scale installation and commissioning of lithium-ion energy storage power stations, the safety of energy storage power stations has also received widespread attention. Most of the fire and explosion accidents in energy storage power stations are caused by thermal runaway of lithium-ion batteries. Therefore, energy storage power stations basically need to be equipped with fire suppression systems to monitor thermal runaway of lithium-ion batteries and suppress fires. However, energy storage power stations are different from power batteries. The battery cells of energy storage power stations are densely distributed and need to communicate with a variety of system accessories and management systems. Therefore, traditional fire suppression devices cannot be directly applied to energy storage power stations. Energy storage power stations need to superimpose other controllers to control the communication of various system accessories and management systems, which easily affects the consistency of the actions of system accessories and increases operation errors.
