Battery Energy Storage Systems (BESS)
Safeguarding the Future of Clean Energy with Proven Early Detection, Monitoring & Suppression
As the world accelerates its transition to renewable energy, Battery Energy Storage Systems (BESS) have become essential to grid stability, peak management, and energy efficiency. However, lithium-ion energy storage introduces unique fire risks, including overheating, instability, off-gassing, and potential thermal runaway. Protecting these systems requires early detection, intelligent control, and coordinated response.
KiddeFenwal delivers an integrated, multi-layered approach engineered specifically for BESS environments. Through advanced anomaly detection, suppression, and remote monitoring, our technologies help identify early warning signs and support mitigation strategies that protect the systems powering a sustainable future.
Built for the Unique Fire Risks of Energy Storage Systems
Lithium-ion batteries can experience internal chemical instability when exposed to thermal, mechanical, electrical, or environmental stress. KiddeFenwal solutions are engineered to detect these conditions long before traditional fire systems can respond.
- Early Detection & Monitoring
REL-iON™ sensors are designed to identify Stage 1 battery abuse conditions — before visible smoke or heat appears, providing critical time for intervention. When a battery enters Stage 2 off-gassing, REL-iON™ detects this chemical signature quickly, enabling operators to initiate mitigation steps that may help prevent or delay escalation into thermal runaway. - Integrated System Intelligence
When paired with KiddeFenwal control panels, REL-iON™ sensors provide continuous, intelligent monitoring, delivering fast, coordinated signaling across detection, alarm, and suppression systems. - Clean, Non-Damaging Suppression
Clean-agent and inert-gas suppression systems provide effective coverage for electrical equipment, system control components, and BESS support infrastructure without leaving residue or damaging electronics. - Remote Visibility Across Distributed Assets
The IntelliSite™ platform transforms fire protection systems into a connected network, offering real-time diagnostics, event-based alerts, and system readiness insights.
