Abstract
A battery pack according to an exemplary aspect of the present disclosure includes, among other things, 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 the battery cell to a location external to the enclosure while preventing ingress of environmental fluids into the enclosure.
Claims20
A battery pack, comprising:
- an enclosure that houses a plurality of battery cells;
- and
- a vent device comprised of a polymeric material and adapted to discharge battery vent byproducts vented by said battery cells to a location external to said enclosure while preventing ingress of environmental fluids into said enclosure,
- wherein said vent device is non-contiguous with a housing of any of said battery cells.
1 more element
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,
- wherein said vent device is separate and remote from said battery cell,
- wherein said vent device includes a vent tube and a removable cap received over said vent tube, and said vent tube includes a barb received within a groove of said removable cap.
2 more elements
A battery pack, comprising:
- an enclosure;
- a plurality of battery cells housed inside said enclosure;
- a vent device extending through said enclosure and including a flap that 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,
- wherein said enclosure is separate from a housing of any of said battery cells.
1 more element
A battery pack, comprising:
- a vent device including a flap that 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,
- wherein said flap is part of a grommet of said vent device.
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,
- wherein said vent device is non-contiguous with a housing of any battery cell housed inside the battery pack.
