flag Huawei's energy storage system passed extreme fire test, meeting new safety standards.

flag Huawei Digital Power's Commercial and Industrial Hybrid Cooling Grid Forming Energy Storage System passed a stringent extreme ignition test at a Chinese national fire safety lab, witnessed by TÜV Rheinland and aligned with the new UL 9540A:2025 standard. flag The test triggered simultaneous thermal runaway in 60 fully charged battery cells under open-door, no-suppression conditions, simulating severe fire scenarios. flag The system maintained structural integrity with an all-metal enclosure resisting over 1500°C, prevented fire spread through a five-level safety design, and self-extinguished within three hours. flag Adjacent cell temperatures stayed at 45.3°C despite fire reaching 961°C, and peak heat release was 3 MW, confirming compliance with the latest safety standard.
