Abstract: A heated battery cell holder includes an upper cell holder having a plurality of holders each configured for securing an upper portion of one of a plurality of battery cells, respectively. A lower cell holder includes a plurality of holders each configured for securing a lower portion of one of the battery cells, respectively. An upper heating element is embedded in the upper cell holder for heating the upper portion of each of the battery cells, and a lower heating element is embedded in the lower cell holder for heating the lower portion of each of the battery cells.

Abstract: A heated battery cell conductor includes an upper conductor having a plurality of tabs each configured for direct physical contact with a battery terminal at a top end of one of a plurality of battery cells, respectively. A lower conductor includes a plurality of tabs each configured for direct physical contact with a battery terminal at a bottom end of one of the battery cells, respectively. The upper conductor and the lower conductor each include a conductor substrate configured for conducting an electrical current, a thermally conductive and electrically isolated layer disposed on the conductor substrate, a channel formed in the thermally conductive and electrically isolated layer, and a resistive heating element disposed in the channel such that the upper conductor and the lower conductor each conduct heat to the battery cells via the resistive heating element.

Abstract: A battery module system includes one or more monoblocks each having one or more cells and a ventilation chamber configured to contain gases vented by the one or more cells. The system includes a channel having an exhaust vent that is in flow communication with each of the one or more monoblocks. A seal is positioned between each ventilation chamber of the one or more monoblocks and the channel and is actuatable when a threshold is achieved in the ventilation chamber associated with the seal.
