A Study to Prevent the Occurrence and Spread of Fire Caused by ESS Storage

ESS 저장창고로 인한 화재의 발생 및 확산방지를 위한 연구

ESS refers to a device that can store electrical energy produced by renewable energy generation, etc. and use it when necessary. Lithium-ion batteries are composed of high energy density and combustible electrolyte, so once ignited, it is difficult to extinguish. Many studies have been conducted to solve the problem of the battery itself as the cause of the fire. However, there is also a problem with the structure in which ESS(hereinafter referred to as ESS storage) is installed itself. Therefore, the purpose of this paper is to provide data to solve the problems related to ignition and fire spread due to the problem of ESS storage. In summer, the internal temperature of the ESS storage rises due to solar radiation to trigger a fire, so it is necessary to prevent an internal temperature rise due to solar radiation. Research on standards, materials used, structures, etc. for ESS storage and new regulations are required.
