Battery module
First Claim
1. A data center battery module, comprising:
- a housing that defines an inner volume and comprises an airflow path from an aperture formed in a first end member of the housing, through the inner volume, and to an aperture formed in a second end member of the housing;
a plurality of power cells mounted in the inner volume of the housing, each of the power cells comprising a vent member at an end of the power cell, the plurality of power cells directionally mounted in the inner volume such that the vent members face an offset direction relative to at least one of the aperture formed in the first end member or the aperture formed in the second end member of the housing, each of the plurality of power cells comprising a lithium-ion battery;
a barrier that at least partially interrupts a fluid pathway that extends between the vent members and at least one of the aperture formed in the first end member or the aperture formed in the second end member of the housing, the barrier comprising a baffle mounted in the inner volume near one of the first or second end members of the housing, the baffle formed from a first baffle portion that extends between sides of the housing and including a gap in a middle of the first baffle portion and a second baffle portion that is positioned offset from and adjacent the middle of the first baffle portion to define a plurality of gaps between the second baffle portion and the sides of the housing; and
an air chamber enclosed in the housing and fluidly decoupled from the airflow path, the air chamber defined between the first and second end members of the housing such that at least one of the vent members is in fluid communication with the air chamber, the air chamber comprising an absorbent material mounted within at least a portion of the air chamber and configured to absorb a liquid electrolyte from at least one of the plurality of power cells, the air chamber comprising at least two openings that fluidly couple the air chamber to an ambient environment external to the housing.

Abstract
A battery module includes a housing that defines an inner volume and includes an airflow path from an aperture formed in a first end member of the housing, through the inner volume, to an aperture formed in a second end member of the housing; power cells mounted in the inner volume of the housing, where each of the power cells includes a vent member; and a barrier that at least partially interrupts a fluid pathway that extends between the vent members and at least one of the aperture formed in the first end member or the aperture formed in the second end member of the housing. The power cells are directionally mounted in the volume such that the vent members face an offset direction relative to at least one of the aperture formed in the first end member or the aperture formed in the second end member of the housing.
