A gap resides between two of the bays and/or enclosures and intumescent material is applied proximate to the gap. The intumescent material is configured to expand when exposed to heat. When a thermal runaway event is caused by the operation of a battery module within an enclosure defined by the crossmembers, the intumescent material expands to at least partially seal each bay and/or enclosure to isolate the individual battery module causing the thermal runaway event and prevent the spread of the heat to battery modules in other bays and/or enclosures.Type: ApplicationFiled: July 28, 2021Publication date: February 2, 2023Inventors: Graham Lloyd Feltham, Travis Cournoyer
