Abstract
Disclosed herein are liquid-cooled battery systems configured to prevent cell-to-cell thermal propagation. In one embodiment, a system includes a section configured to generate and store electrical energy through heat-producing electro-chemical reactions. A cooling system may be configured to generate a flow of a liquid coolant through the battery system to remove heat produced by the battery. Cooling fins may be configured to receive the flow of the liquid coolant through a primary coolant channel and to transfer heat from the battery to the liquid coolant. The cooling fins may also include a secondary coolant channel configured to be at least partially filled with a melting material configured to obstruct the liquid coolant from exiting through the aperture at temperatures below a temperature threshold. When the melting material melts, it permits some of the liquid coolant to exit the cooling fin and wet and cool the adjacent battery section.
