Abstract
An exemplary assembly includes an enclosure wall of an enclosure that houses at least one battery cell, and a vent of the enclosure wall. The vent is configured to move from a first position to a second position in response to an increase in a pressure within an interior of the enclosure. The vent in the second position provides a passage to discharge battery vent byproducts from the interior. An exemplary battery pack venting method includes moving a vent of an enclosure wall from a first position to a second position in response to an increase in a pressure within an interior of an enclosure having the enclosure wall. The vent in the second position provides a passage to discharge battery vent byproducts from the interior.
