Fire Hazards of Battery Energy Storage Systems

This technical information paper discusses the fire hazards associated with Battery Energy Storage Systems (BESS). It outlines how BESS operates as an electrochemical device that charges energy from various sources and discharges it when needed. The paper details the different types of BESS, including their power and energy ratings, and the various battery chemistries used, such as Lithium-Ion and lead-acid. It highlights the growing applications of BESS in commercial and residential settings, particularly in conjunction with renewable energy sources. The document emphasizes the potential fire risks linked to BESS, particularly those involving lithium-ion batteries, which can lead to thermal runaway and explosions. It describes the causes of such hazards, including mechanical damage, manufacturing defects, and excessive overcharging. The paper also notes the importance of proper installation and maintenance to mitigate these risks, as well as the implications of recent fire incidents in BESS installations.
