Condensed aerosol fire suppression is a line protection solution for energy storage systems (ESS) and battery energy storage systems (BESS) applications. This includes in-building, containerized, and in-cabinet applications. Aerosol systems provide highly effective battery room fire protection. What is a lithium battery? A lithium-ion battery or li-ion battery is a type of rechargeable battery in which lithium ions move from the negative. That's why safety is a top priority in BESS installations, and advanced fire suppression systems, such as aerosol fire extinguishing, have become an essential part of the solution. Lithium-ion batteries, commonly used in BESS, are susceptible to thermal runaway—a chain reaction that can lead to. FirePro technology has successfully proven its efficiency and effectiveness in suppressing Li-Ion battery fires in more than 100 tests carried out over the past 7 years by accredited laboratories and prominent Li-Ion battery manufacturers. Technological advancements in the chemistry, configuration. Thermal runaway is the leading cause of lithium battery fire. When a single defective cell, or one that has been subjected to mechanical, electrical, or thermal abuse, may lead to an increase in its internal temperature, triggering a thermal runaway.
