Abstract: A battery pack includes a battery pack enclosure surrounded by an external environment and housing battery cells. The battery pack enclosure includes a tray having a first compartment housing the battery cells and a second compartment configured to collect high-temperature gas emitted by the battery cell(s) during a thermal runaway and expel the gas to the external environment. The battery pack enclosure also includes a cover configured to engage the tray and seal the enclosure. The first compartment is arranged between the second compartment and the cover. The battery pack also includes a temperature-sensitive component arranged inside the enclosure between the second compartment and the cover. The battery pack additionally includes a vent channel fluidly connecting the first and second compartments and configured to direct the high-temperature gas from the first compartment to the second compartment, thereby diverting the gas away from the temperature-sensitive component.
