Abstract:

Battery energy storage system has broad development prospects due to its advantages of convenient installation and transportation, short construction cycle, and strong environmental adaptability. However, battery safety accidents of energy storage systems characterized by thermal runaways occur frequently, which seriously threatens power consumption and life safeties of relevant personnel with the continuous improvement of overall energy density and the reduction of manufacturing costs. Therefore, the research on preventing thermal runaway of battery energy storage systems has recently become a hot spot in the field of the energy storage system. From the perspective of energy storage battery safety, the mechanism and research status of thermal runaway of container energy storage system are summarized; the cooling methods of the energy storage battery (air cooling, liquid cooling, phase change material cooling, and heat pipe cooling) and the suppression measures of thermal runaway are introduced, and the latest research results are reviewed. This paper expounds on the influence of temperature and humidity on batteries, comprehensively outlines the methods to improve the safety and reliability of container energy storage systems, and projects the development direction of thermal management technology. This paper aims to promote the development of safety management methods and strategies of the energy storage system and then improve the energy storage system's safety.
