Energy Storage Station Electrical Fire Protection Solution

Electrical Fire Causes in Energy Storage Stations

Lithium battery energy storage systems have high energy density and pronounced thermal runaway risk; once ignited, fire spreads quickly and re-ignition risk is significant:

Lithium battery thermal runaway: internal short circuit or overcharge triggers thermal runaway, releasing flammable gases that ignite neighboring cells
PCS electrical fault: aging or short circuit of converter power modules causes direct ignition on the DC bus side
DC arcing: poor contact at battery cluster busbars and connectors sustains arcing that ignites cable sheathing
Re-ignition and spread: residual short-circuit energy after conventional suppression may cause secondary re-ignition, spreading to adjacent containers

The core principle of fire protection for energy storage stations is "early detection, fast suppression, and spread prevention" — intervening actively at the early stage of thermal runaway intervening at the early stage of thermal runaway.

Solution Overview

This solution applies AFCP composite agile fire-control patches over battery pack surfaces and PCS power modules, deploys EAPD devices to monitor abnormal temperature, smoke, and combustible gas concentration inside the container, and connects the ICOP platform to the BMS and fire system for integrated response — building an active storage protection system of "cell-level patch protection, in-container monitoring and warning, and platform-based coordinated control."

Overall approach: AFCP patches are mounted directly on the top cover and sides of battery packs and on PCS power module surfaces — the direct points where thermal runaway originates. When abnormal high temperature occurs (e.g., shell temperature rising sharply due to an internal cell short circuit), the patch actively ruptures and releases a clean extinguishing agent to suppress local hot spots before thermal spread. EAPD devices continuously monitor the container environment; abnormal parameters and BMS data are cross-analyzed on the ICOP platform to trigger graded alarms and coordinated response.

Core Product Configuration

AFCP Composite Agile Fire-Control Patch

A single patch provides on-site protection, addressing electrical fire risks at the source:

Cell-level protection: closely attached to the battery pack surface, releases clean agent upon early thermal runaway signs to suppress local hot-spot spread
No new risk introduced: purely passive physical trigger, no electromagnetic interference to BMS or battery management systems
No secondary damage: clean agent is non-conductive and residue-free, not affecting normal operation of cells and PCS
Adapts to varied conditions: patch structure tolerates the day-night temperature swings and vibration of storage containers for long-term reliability

EAPD Electrical Active Protection Device

Very early warning that actively suppresses before a fire develops; it focuses on monitoring in-container thermal runaway signature parameters such as temperature, smoke, and carbon monoxide, reporting anomalies to the ICOP platform and coordinating ventilation pre-action and suppression.

ICOP Intelligent Integrated Operation Platform

Connects to the storage station BMS and EAPD data, cross-analyzing thermal runaway precursors from multiple sources; supports graded alarm push and fire-coordination plans for full-lifecycle safety management of the storage station.

Key Technical Parameters

Protection method	Cell-level patch protection + in-container monitoring + platform BMS coordination
Extinguishing agent	AFCP clean extinguishing agent (non-conductive, residue-free)
Monitoring focus	EAPD temperature / smoke / CO thermal runaway signature monitoring
Deployment form	Patches pre-mounted on pack top cover; EAPD on container wall; ICOP cloud/local deployment
Applicable equipment	Battery pack, PCS, busbar, DC distribution cabinet
Unified management	ICOP coordinates with BMS for centralized control and fire linkage of multiple storage container groups

Benefits After Deployment

Cell-level suppression

Patches directly cover individual cell hot spots, actively suppressing before thermal spread

Multi-parameter warning

EAPD jointly analyzes with BMS to reduce false and missed alarms

Spread barrier

Multiple in-container patches form a suppression surface to contain thermal runaway within the container

Low-maintenance operation

Patches are maintenance-free; EAPD self-checks and reports; ICOP remote watch reduces site visits

Extended Application Scenarios

This solution also applies to commercial and industrial storage cabinets, PV-plus-storage, and integrated PV-storage-charging stations. The core logic is consistent — battery pack patch protection, multi-parameter in-container EAPD monitoring, and ICOP coordination with the BMS. It can be used together with other AFCP patch series and Liquid Shield coating.

Standards and Compliance

This solution's technical approach references electrical fire protection design codes for energy storage stations and the AFCP series enterprise standards, using clean non-conductive extinguishing agent suitable for active protection of energized storage equipment. Combined with the EAPD device and ICOP platform, it follows the "monitoring — warning — local suppression" active safety technical approach for energy storage.
