Early Detection of Cell Venting in Battery Storage Systems – The Key to Fire Safety

Synopsis

Venting events in lithium-ion batteries are critical early indicators of thermal runaway and potential fires. Timely detection enables preventive actions such as shutdown, cooling, or targeted alarms, and is essential for protecting people and infrastructure. 

During venting, toxic and flammable gases such as carbon monoxide and hydrogen are released, which can lead to dangerous deflagrations in enclosed spaces. Without appropriate sensor technology, the fire detection system remains blind to these events. 

Modern sensor systems – including gas detectors and advanced aspirating smoke detectors – enable reliable detection and integration into automated safety processes. As such, venting detection becomes an indispensable part of a comprehensive fire protection strategy for battery storage systems.
