A battery pack, comprising:
- an enclosure that houses at least one battery cell;
- and
- a vent device comprised of a polymeric material and adapted to discharge battery vent byproducts vented by said battery cell to a location external to said enclosure while preventing ingress of environmental fluids into said enclosure.
A battery pack, comprising:
- a vent device including a flap this is movable between a first position and a second position to expose an outlet of said vent device if a pressure inside said vent device exceeds a threshold pressure.
A battery pack, comprising:
- a vent device configured to plastically deform at a predefined failure area to expose an outlet of said vent device if a pressure inside said vent device exceeds a threshold pressure.
