AI Technical Summary

Technical Problem

Conventional methods for controlling thermal events in battery racks are inefficient as they spray fire extinguishing agents over a wide area, making it difficult to quickly and effectively manage temperature rises in battery cells.

Method used

A battery rack design that includes a fire extinguishing agent supply module directly connected to the battery module, supported by a support module that is securely fastened to the rack frame, allowing for direct and stable discharge of extinguishing agents, even under vibrations.

Benefits of technology

This configuration enables quick suppression of thermal events by directly targeting affected battery modules and withstands vibrations, ensuring stable and efficient fire extinguishing.
