Sealed interface between thermal barrier assembly and adjacent structure within traction battery pack

The present disclosure provides a sealed interface between a thermal barrier assembly and an adjacent structure within a traction battery pack. A thermal barrier assembly for use within a traction battery pack is provided. An example thermal barrier assembly may include features for establishing a sealed interface with respect to one or more adjacent structures of a traction battery pack. In some embodiments, the thermal barrier assembly may provide features for interfacing with a cell stack cross member beam, an upper shell structure, a lower shell structure, and the like. The sealed interface substantially prevents thermal energy from moving between compartments/cell packets during a battery thermal event. 本公开提供了"牵引电池包内的热障总成与相邻结构之间的密封接口"。提供了用于在牵引电池包内使用的热障总成。示例性热障总成可以包括用于相对于牵引电池包的一个或多个相邻结构建立密封接口的特征件。在一些实施方式中，热障总成可以提供用于与电芯堆横向构件梁、上部外壳结构、下部外壳结构等对接的特征件。密封接口在电池热事件期间基本上防止热能在隔室间/电芯小包间移动。
