요약
최근 국내 ESS의 보급이 늘어나면서 화재사고 또한 발생하고 있다. 2018년 7월까지 총 7건이 발생하였다. 7건 모두 리튬이온배터리로 구성된 ESS 시스템으로 발화 이후 자동소화설비 또는 소방서에 의해 진화되지 못하고 전소되었다. 본 논문에서는 최근 발생한 ESS 화재현황 및 현장조사를 바탕으로 ESS 화재의 특징을 파악하고 발화원인을 환경적, 전기적, 열적 요인으로 나누어 분석하였다. 그 결과 ESS 화재가 시스템의 설치환경과 상관관계가 있음을 파악하였다. 국내외 리튬이온배터리 시험표준 및 ESS 시설기준 조사에서는 국내외 동향 및 차이점을 파악하였다. 화재현황 및 현장조사, 국내외 시설기준 조사 등을 토대로 ESS 화재 시 화재 확산을 방지하고 예방하기 위한 대책을 제시하였다.
Abstract
Recently, the spread of ESS in Korea has increased and a fire accident has also occurred. By July 2018, there were a total of 7 cases. All 7 cases were ESS systems consisting of lithium-ion batteries and were burned down. Both the automatic fire extinguisher and the fire department were not able to digest. In this paper, the characteristics of ESS fire are analyzed based on recent ESS fire situation and field investigation, and the cause of fire is divided into environmental, electrical and thermal factors. As a result, it was found that the ESS fire was correlated with the installation environment of the system. In the domestic and overseas lithium ion battery test standard and ESS facility standard survey, the trends and differences of domestic and overseas facilities standards were identified. Based on the fire status and field investigationy, and domestic and overseas facility standard survey, measures were suggested to prevent and prevent the spread of fire in ESS fire.
Key Words: ESS, Li-ion battery, Thermal runaway, Ignition, Facility standards
