Battery module with sealed vent chamber

A battery system for use in a vehicle, the battery system comprising:

• a plurality of battery modules, each module comprising a plurality of electrochemical cells that each include a casing, a vent configured to deploy from a first end of the casing, and a seal fixed to the casing proximate the first end of the casing;
• and
• at least one structure defining at least one 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.

A battery module, comprising:

• a structure defining a chamber and comprising a plurality of sockets;
• and
• a plurality of electrochemical cells, wherein each electrochemical cell is provided in one associated socket of the structure, wherein each electrochemical cell includes a casing, a vent configured to deploy from a first end of the casing into the chamber, and a seal fixed to the casing proximate the first end of the casing, and wherein each of the seals is configured to seal gases vented into the chamber from escaping the chamber through the plurality of sockets.
