Abstract: A battery pack comprising a housing defining a volume. The battery pack includes a battery module arranged within the housing, where the battery module comprises a plurality of battery cells configured to provide an electrical output. The battery pack includes a first detector positioned within the battery module proximate to the plurality of battery cells, where the first detector is configured to detect a deformation of one of the plurality of battery cells to identify a potential thermal runaway.

Abstract: A battery system including a housing defining an aperture and an internal volume, a battery section contained within the internal volume, and a seal coupled to the housing and reconfigurable from a sealed state to a ruptured state in response to a predetermined condition within the housing. In the sealed state, the seal prevents fluid from flowing through the aperture. In the ruptured state, the seal permits the fluid to flow through the aperture.

Abstract: A container system includes a shipping container including multiple battery cells and a fire suppression system. The fire suppression system includes multiple fire suppressant containers and processing circuitry. The fire suppressant containers are each configured to store fire suppressant and discharge the fire suppressant to a coverage area of the shipping container. The processing circuitry is configured to obtain detection data indicating a detection of a thermal event or a fire within the shipping container. The processing circuitry is configured to, in response to the detection of the thermal event or the fire within the shipping container, sequentially activate the fire suppressant containers to provide fire suppression according to multiple stages of fire suppression.

Abstract: A battery pack comprising a housing defining a volume and a battery module arranged within the housing, where the battery module comprises a plurality of battery cells configured to provide an electrical output. The battery pack comprising a suppressant canister having a suppressant and positioned within the battery module proximate to the plurality of battery cells, where the suppressant canister is configured to provide the suppressant to the battery module to mitigate a thermal runaway.

Abstract: A battery system includes a housing assembly including an inner wall and an outer wall and a battery section. The housing assembly defines an inner volume, a distribution volume extending between the inner wall and the outer wall, the inner wall extending between the inner volume and the distribution volume, a first aperture and a second aperture each extending through the inner wall from the inner volume to the distribution volume, and an inlet fluidly coupled to the distribution volume and configured to be fluidly coupled to a supply of fire suppressant. The battery section is positioned within the inner volume.

Abstract: A container system includes a container, and a canister. The container defines an inner volume. Multiple modules are positioned within the inner volume. The modules include multiple battery cells. The canister is configured to store liquid CO2. The canister is removably fluidly coupled with the inner volume of the container. The canister is configured to discharge the liquid CO2 into the inner volume to suppress and freeze the battery cells prior to physical opening of the container.

Abstract: A method of extinguishing or abating a lithium battery fire includes administering to the lithium battery fire a firefighting composition including a surfactant component including one or more non-ionic surfactants; a polysaccharide component; and water.

Abstract: A system for providing fire suppression includes multiple capsules and a suppression system. The capsules may be positioned proximate a hazard. Each capsule includes a wall configured to rupture in response to a particular temperature or in response to fluidic contact. The capsules are each configured to store a suppressant agent within the wall of the capsule. The suppression system is configured to discharge a fluid to the hazard in response to a thermal condition at the hazard. The fluid is configured to react with the suppressant agent to provide fire suppression to the hazard.
