"textContent": "A battery pack includes one or more battery modules subject to generating hot vent gasses during a thermal runaway event, a housing enclosing the battery modules therein and defining perimeter vent openings, and a plurality of perimeter vent assemblies. Each vent assembly is connected adjacent a corresponding one of the vent openings, and includes a translatable member, a gas diffuser block, and at least one sacrificial post. The gas diffuser block is connected to an outer surface of the housing, covers a respective one of the vent openings, and defines a plurality of orifices. The at least one sacrificial post is configured to melt or incinerate at a predetermined temperature to cause the translatable member to translate relative to the diffuser block and thereby prevent the vent gasses from escaping the battery pack.",
