Abstract
Systems and methods are described herein for venting battery cells in a battery cell pack assembly. An assembly includes a matrix configured to hold battery cells and channel assemblies that each include a venting channel for venting materials (e.g., flammable gas and conductive particulates) from the interior of the matrix to an outlet. Battery cells, particularly lithium ion battery cells, have a chance of entering a thermal runaway condition that causes the production of flammable gas. The assembly is configured such that battery cells are allowed to vent such flammable gas out of the assembly. A ventilation opening and channel in the assembly cause venting materials to be routed through and out of the assembly.
