The energy storage system is a system that increases energy efficiency by storing electrical energy in a storage device and supplying it when it is needed.In Korea, it was rapidly spread in 2018 starting in 2013. However, the decline has continued since 2019 due to fires related to the energy storage system battery. At present, no clear cause of fire has been identified, and fire extinguishing facilities and regulations for an appropriate energy storage system have not been established. Currently, battery manufacturers and other firefighting equipment companies are researching and applying fire extinguishing facilities and fire extinguishing systems suitable for lithium battery characteristics. In the case of a battery of an energy storage system, it is possible to prevent a large-scale fire from spreading only when a fire extinguishing work is performed on the battery module and the battery cell, which is an ignition point due to structural characteristics. In this paper, through research and experiments on a fire extinguishing device that can be installed separately for the existing battery module, it was confirmed that flames can be detected when igniting each cell inside the battery, and the spread of fire within the module can be prevented through the fire extinguishing operation.
