AI Technical Summary
Technical Problem
Conventional battery packs fail to effectively suppress heat propagation and flame leakage between battery modules, leading to rapid pack collapse and external fire spread during thermal events.
Method used
A battery pack design featuring a flame blocking unit with a metal cover supported by a compression spring mechanism, which lifts to mitigate pressure and includes gas venting holes, preventing flame spread and allowing controlled gas release.
Benefits of technology
Delays battery pack collapse and maximally suppresses flame leakage, protecting adjacent modules and reducing external fire risk.

Abstract
A battery pack according to the present invention may include: a plurality of battery modules; a pack tray having an open top and an internal space capable of accommodating the plurality of battery modules, and a beam frame disposed between the battery modules adjacent to each other and partitioning the internal space; a pack cover covering the top of the pack tray; and a flame blocking unit connected to the beam frame and configured to cover a corresponding battery module at the bottom of the pack cover to block flames emitted from the battery modules.
