Energy Storage
Lithium-ion battery energy storage systems face thermal runaway risks, rapid fire propagation, re-ignition, and hazardous gas release. Advanced solutions for early detection, explosion protection, and fire suppression are essential.
Key Challenges
Early Detection Challenges
Thermal runaway events are difficult to detect in their early stages.
Toxic and Combustible Gases
Battery failures may release hazardous gases, including hydrogen (H₂) and carbon monoxide (CO).
Rapid Fire Propagation
Fires can spread quickly and may re-ignite after suppression.
High-Density Battery Layouts
Closely spaced battery clusters can accelerate fire propagation.
Detection Challenges in Enclosed Containers
Fire and gas detection can be more difficult in containerized energy storage systems.
Electromagnetic Interference
Strong electromagnetic interference can affect system reliability and equipment performance.
Battery Container / Battery Compartment
Challenges by Area
- Smoke detectors may trigger false fire alarms due to electromagnetic interference
- There is little obvious smoke in the early stage of lithium-ion battery thermal runaway, delaying the response of conventional detectors
- Combustible gases may accumulate in the enclosed space, creating a high explosion risk
- Densely arranged battery clusters allow thermal runaway to propagate rapidly
- High reignition risk and difficult firefighting
Solutions
- Use interference-resistant smoke detectors to reduce false alarms
- Add combustible gas detectors in the battery compartment to detect H₂ and CO for multidimensional detection
- Use dedicated carbon monoxide and combined smoke/heat fire detection devices for battery PACKs in energy storage stations to jointly detect characteristic early-stage thermal-runaway gases, smoke, and temperature
- Link to the gaseous fire-extinguishing system for early suppression
