Abstract
Methods and systems for creating a battery module. A battery cell can include a vent in the bottom of the battery. To allow the battery to be attached to a cooling plate and allow the vent to function properly, an opening is formed in the cooling plate under the battery. The opening can vent gasses from the vent in the battery to atmosphere through a chamber in the cooling plate or a conduit in the cooling plate.
Claims20
A battery module comprising:
- a cooling plate comprising:
- a first chamber disposed within a body of the cooling plate to circulate a first material that cools the cooling plate;
- a second chamber disposed within a portion of the first chamber, wherein the second chamber is physically separate from the first chamber;
- and
- an opening in a top portion of the cooling plate that opens into the second chamber;
- and
- a battery joined to the cooling plate over the opening, wherein a vent in a bottom of the battery vents through the opening in the cooling plate and into the second chamber.
