Battery module with sealed vent chamber
First Claim
1. A battery module having a sealed vent chamber, the battery module comprising:
- a plurality of electrochemical cells each having a housing, a vent configured to deploy from a first end of the housing, and a seal fixed to the housing proximate the first end of the housing; and
a structure defining a chamber and comprising a plurality of sockets, wherein each socket is configured to receive one of the plurality of electrochemical cells such that the vent of each of the electrochemical cells is located in the chamber and such that the seal of each of the electrochemical cells seals against the respective socket, wherein the seals are configured to seal gases vented into the chamber from escaping the chamber.

Abstract
A battery module having sealed vent chamber includes a plurality of electrochemical cells each having a vent at an end thereof. The module also includes a structure defining a chamber and comprising a plurality of sockets, each socket configured to receive one of the plurality of electrochemical cells such that the vents of the electrochemical cells are located in the chamber. The module further includes a seal provided between at least one of the electrochemical cells and its associated socket. At least a portion of the seal is deformable such that gases released from the electrochemical cells into the chamber compress the deformable portion of the seal against the electrochemical cells to seal the gases in the chamber.
