Abstract: A battery module includes a first battery cell and a neighboring second battery cell, and an insulating member positioned therebetween. The battery module also includes a battery module enclosure surrounded by an external environment and configured to house each of the first battery cell, the second battery cell, and the insulating member. The battery module additionally includes a battery module cover mounted to the battery module enclosure. The battery module cover includes a vent feature configured to expel high temperature gases from the first battery cell and divert the high temperature gases away from the second battery cell directly to the external environment. The cover is thereby configured to minimize transfer of the high temperature gases from the first battery cell to the second battery cell and control propagation of a thermal runaway event in the battery module.

Abstract: A battery includes a housing having a base. A battery cell stack and an enclosure are supported on the base of the housing. The battery cell stack includes a plurality of battery cells physically separated into a first battery cell group and a second battery cell group. The enclosure includes first and second support walls respectively disposed on opposite first and second sides of the first battery cell group and a canopy extending between the first and second support walls, above the first battery cell group. The enclosure partially surrounds the first battery cell group on three sides and establishes a physical and thermal barrier between the first battery cell group and the second battery cell group.
