Abstract
A system includes a vent housing configured to be installed on a lower housing of a battery module at a first side of the vent housing. The vent housing has a main body having an opening on a second side of the vent housing and an internal chamber coupled to the opening. The internal chamber includes a first wall having an internal burst vent configured to open at a first pressure threshold and a second wall having a ventilation vent comprising a gas-selective permeability layer.

A system, comprising:
- a lower housing sized to hold a plurality of lithium-ion electrochemical cells and having a first connection surface;
- and
- a vent housing configured to couple with the lower housing, comprising:
- a main body having a second connection surface configured to mate with the first connection surface;
- an opening in a face of the main body, the face being oriented generally crosswise relative to the second connection surface;
- and
- an internal chamber coupled to the opening and comprising an internal burst vent and a ventilation vent, wherein the ventilation vent comprises a gas-selective permeability layer.
4 more elements
A system, comprising:
- a lower housing holding a plurality of lithium-ion electrochemical cells;
- and
- a vent housing coupled to the lower housing such that the cavity is sealed at an internal pressure, wherein the vent housing comprises:
- a main body having an opening on a face of the vent housing;
- and
- an internal chamber coupled to the opening, wherein the internal chamber comprises a first wall having an internal burst vent configured to open when the internal pressure rises above a first pressure threshold, and a second wall having a ventilation vent configured to enable gas exchange between the internal chamber and the cavity.
