A: Layer panga chu a hnungzuiin a kang: cell BMS chuan anomaly chu a flag in<500ms and isolates it; module fuses cut fault current before propagation; rack-level ceramic barriers block heat transfer physically; if temperature or gas levels still rise, the cabinet's perfluorohexanone + aerosol system floods the compartment automatically (no residue, no electronic damage); and finally the STS disconnects the entire cabinet from the grid in ≤20ms. Because this is LiFePO4 - not NCM or NCA - the failing cell does not release oxygen, which is the main propagation driver in ternary chemistries. No layer depends on another to function.

A: At default EMS settings (5% bottom SOC reserve, 2% top), usable DC capacity is ~224 kWh per cycle. Multiply by ≥86% AC-AC round-trip efficiency (at 25°C, 0.5C) and you get roughly 193–207 kWh AC delivered to load - the range depends on ambient temperature and C-rate.

A: The centralized EMS runs a weighted SOC balancing algorithm each control cycle (~100ms): cabinets with higher SOC discharge proportionally more, lower-SOC units receive more charge current. This keeps all cabinets within a tight SOC band and prevents any single unit from cycling disproportionately - which is the main cause of uneven aging in parallel BESS systems. Each cabinet retains independent BMS and PCS, so if one trips on a fault, the others absorb its load seamlessly. Communication: Modbus-TCP over Ethernet, 1-second polling.
