Present embodiments are directed to a battery module including a venting assembly and a method of manufacturing the battery module. The venting assembly may, in certain embodiments, be designed to vent gases from a plurality of battery cells disposed in a housing of the battery module. Each of the plurality of battery cells may include a battery cell vent. The venting assembly may include a lid designed to be coupled to the housing and disposed over the battery cells in the housing. In some embodiments, the lid includes a vent chamber formed in the lid and designed to receive and direct gases vented from the plurality of battery cells away from the battery module.

1. A battery module, comprising: a housing comprising a lid, the lid being a molded single structure;a venting assembly having a vent guide disposed within a vent chamber, wherein the vent chamber is defined by a slot in the lid;a plurality of prismatic battery cells disposed in the housing, wherein the plurality of prismatic battery cells are spaced apart from one another along a first direction, wherein each of the plurality of battery cells comprises a battery cell vent for venting gases from within the corresponding battery cell;a printed circuit board (PCB) configured to control operations of the battery module, wherein the PCB is disposed on a side of the lid opposite the plurality of battery cells, wherein the battery cell vents of each of the plurality of battery cells are configured to vent the gases upward in a second direction toward the PCB, wherein the second direction is substantially perpendicular to the first direction; andwherein the vent chamber and the vent guide are disposed between the plurality of battery cells and the PCB such that the plurality of prismatic battery cells vent directly into a single cavity formed by respective tops of each battery cell of the plurality of battery cells and the vent guide, wherein the vent guide is a U-shaped plate positioned within the vent chamber to prevent the vented gases from directly contacting the lid, wherein the vent guide is disposed into the lid and is directly adjacent to the respective tops of the plurality of battery cells, wherein the venting assembly is configured to direct the gases vented into the single cavity toward an opening for venting the gases from the battery module, wherein the venting assembly comprises a first end disposed above one of the plurality of prismatic battery cells proximate the opening and a second end disposed above another of the plurality of prismatic battery cells that is farthest from the opening, wherein the vent guide is tapered along a third direction substantially perpendicular to each of the first and second directions such that a first width of the vent guide is larger at the first end than a second width of the vent guide at the second end. 2. The battery module of claim 1, wherein the lid holds the PCB above the plurality of battery cells, and wherein the vent chamber comprises a hollowed out portion of the lid. 3. The battery module of claim 1, wherein the opening is disposed in substantially the same plane as the vent chamber. 4. The battery module of claim 1, wherein the opening comprises a chimney extending from the battery module. 5. The battery module of claim 4, wherein the chimney comprises a hose fitting configured to be coupled to a venting system in a vehicle. 6. The battery module of claim 1, wherein the housing comprises the opening for venting the gases from the battery module. 7. The battery module of claim 1, comprising a cover disposed over the housing to seal the battery module, wherein the cover comprises the opening for venting the gases from the battery module. 8. The battery module of claim 1, wherein the vent chamber is tapered such that a first width of the single cavity is larger at the first end than a second width of the single cavity at the second end.
