Battery pack exhaust system and exhaust method

The invention provides a battery pack exhaust system and an exhaust method. A battery pack venting system includes a traction battery pack having at least one array of battery cells and a structural member having an interior. The array is configured to exhaust gas into the interior. A traction battery pack venting method includes opening a vent opening to an interior of a structural member. At a location between a first axial end of the structural member and an opposite second axial end of the structural member, the method includes discharging gas from at least one array of traction battery packs into the interior; and then exhausting the gas from the interior. 本公开提供"电池包排气系统和排气方法"。一种电池包排气系统包括具有至少一个电池电芯阵列的牵引电池包以及具有内部的结构构件。所述阵列被配置为向内部中排气。一种牵引电池包排气方法包括打开通向结构构件的内部的排气孔。在结构构件的第一轴向端部与结构构件的相对的第二轴向端部之间的位置处，所述方法包括将气体从牵引电池包的至少一个阵列排放到内部中；以及然后从内部排出气体。
