Thermal barrier assembly for traction battery pack

The present disclosure provides a thermal barrier assembly for a traction battery pack. An exemplary thermal barrier assembly may be configured to block or even prevent thermal energy associated with a battery thermal event from moving within the traction battery pack from a cell to a cell, from a compartment to a compartment, and/or from a cell stack to a cell stack. The thermal barrier assembly may include features such as a protective housing and a thermally insulating barrier disposed within the protective housing. For example, the protective housing may be made of a metal, ceramic, or polymer material. For example, the thermal insulation barrier may include an aerogel, foam, or inorganic paper. 本公开提供了"用于牵引电池包的热障总成"。一种示例性热障总成可被配置为阻挡或甚至防止与电池热事件相关联的热能在所述牵引电池包内从电芯移动到电芯、从隔室移动到隔室和/或从电芯堆移动到电芯堆。所述热障总成可包括诸如保护壳体和设置在所述保护壳体内的热绝缘屏障等特征件。例如，所述保护壳体可由金属、陶瓷或聚合物材料制成。例如，所述热绝缘屏障可包括气凝胶、泡沫或无机纸。
