Thermal runaway of lithium batteries is a major safety concern in the energy storage industry. PFCS patches cover battery pack and PCS surfaces, EAPD monitors in-container temperature and gas parameters, and the ICOP platform integrates with the BMS to form an active protection system from the cell level to the entire container.
Lithium battery energy storage systems have high energy density and significant thermal runaway risk; once ignited, fire spreads quickly and re-ignition risk is significant:
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.
This solution applies PFCS 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: PFCS 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.
A single patch provides on-site protection, addressing electrical fire risks at the source:
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.
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.
| Protection method | Cell-level patch protection + in-container monitoring + platform BMS coordination |
|---|---|
| Extinguishing agent | PFCS 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 |
Patches directly cover individual cell hot spots, actively suppressing before thermal spread
EAPD jointly analyzes with BMS to reduce false and missed alarms
Multiple in-container patches form a suppression surface to contain thermal runaway within the container
Patches are maintenance-free; EAPD self-checks and reports; ICOP remote watch reduces site visits
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 PFCS patch series and Liquid Shield coating.
This solution's technical approach references electrical fire protection design codes for energy storage stations and the PFCS 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.

The two are not additive; they interact, and the protective strategy must reflect the interaction. CHILION's energy storage solution is engineered specifically around that interaction, with instrumentation that monitors both battery-side parameters and conversion-side parameters in parallel. The protective logic understands whether an abnormal signature originates in the battery string, in the conversion equipment, or somewhere in the electrical interface between them. The action set is also tailored: battery-side anomalies typically pace toward a controlled shutdown path rather than an immediate interruption, while conversion-side anomalies follow the more conventional interruption logic. The result is a coordinated protective system that respects the different physics of each subsystem without sacrificing response time on either side.
Energy storage sites are often commissioned while partially in operation, particularly when the deployment follows a phased capacity build. The CHILION commissioning workflow is designed for that pattern: instrumentation is installed in the new cabinets without disturbing the in-service cabinets, and validation proceeds cabinet-by-cabinet as each new section energizes. The phased pattern repeats as subsequent capacity blocks come online, with a single coherent commissioning record that spans the whole site. This approach minimizes the operational risk inherent in retro-commissioning a partly live facility and produces documentation that is uniform across the whole site rather than inconsistent across subsections. Operators and auditors both prefer the uniform pattern because it simplifies both routine inspection and incident review.
Field feedback from across our installed base flows into our quarterly product-development cycle. Customers who participate in our field-feedback program see their observations reflected in subsequent firmware revisions, configuration improvements, and accessories. This is the loop that distinguishes a vendor with an installed base from a vendor with a marketing channel: the latter collects feedback into a presentation, the former collects feedback into a roadmap.
