AI Technical Summary
Technical Problem
Existing battery assemblies and packs face challenges in effective cooling during rapid charging and in suppressing heat transfer between cells, which can lead to thermal events and potential fires or explosions.
Method used
A battery assembly with a cell frame covering each battery cell, a heat sink with cooling plates between cells, and a venting system to direct high-temperature gases and particles away from adjacent cells, combined with a pack frame that houses the assembly and allows venting.
Benefits of technology
The solution provides enhanced cooling performance and minimizes thermal event propagation, reducing the risk of fires or explosions by directing venting gases and particles away from adjacent cells.

Abstract
A battery assembly according to one embodiment of the present invention includes a plurality of battery cells stacked in one direction, a cell frame that extends along the periphery of each of the battery cells and covers the periphery of the battery cells, and a heat sink having at least one cooling plate positioned at at least one location between the battery cells. A cell vent is formed in the portion of the cell frame corresponding to the lower end of the battery cell.
