Document Type and Number:
WIPO Patent Application WO/2022/154278
Kind Code:
A1
Abstract:
The present invention relates to a system for thermal runaway prevention and fire prevention in an energy storage system (ESS), comprising: detection parts for detecting thermal runaway in which a temperature rise change in battery modules of the ESS is accelerated; carbon dioxide discharge valves for discharging low-temperature carbon dioxide gas toward the battery modules by the control of the detection parts; air current generation parts arranged at the ends of the discharge valves to discharge the low-temperature carbon dioxide gas toward the battery modules, and thus generate a high-pressure and low-temperature air current; and water mist discharge valves for discharging a water mist spray toward the battery modules by the control of the detection parts.
