Abstract: A thermal runaway detection and prevention system. The system comprises one or more thermopiles configured to measure one or more thermal characteristics of a monitored area, and a controller having one or more processors and a memory storing instruction that, when executed by the one or more processors, cause the one or more processors to perform operations. The operations may comprise identifying the one or more thermopiles in the monitored area, and receiving, from the one or more thermopiles, thermal signals relating to one or more measured thermal characteristics of the monitored area. The operations may also comprise detecting, based on the thermal signals, a potential thermal runaway event, and initiating a control decision in response to detecting the potential thermal runaway event.

Abstract: Assembly and apparatus related to a fire suppression system are described herein. The nozzle cap and insert assembly includes a discharge nozzle, a cap insert, and a nozzle cap. The discharge nozzle includes an aperture on an elongated body such as a cylinder. The cap insert includes a plate and, in some implementations, a sidewall and a perforation. The nozzle cap incudes a cavity with a depth equal to a thickness of the plate of the cap insert and a length of the discharge nozzle. The diameter of the cap insert is structured to substantially or completely cover the top of the discharge nozzle and the thickness of the plate is structured to fit inside the cavity of the nozzle cap. The cap insert is made of a heat-resistive rigid material, similar or the same as the metal of the discharge nozzle.

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 includes a housing defining a volume, and a battery module arranged within the housing, where the battery module includes a plurality of battery cells configured to provide an electrical output. The battery system also includes a cooling system having a cooling channel, the cooling channel configured to pass within the battery module and is arranged adjacent the plurality of battery cells, where the cooling channel is configured to facilitate temperature control of the battery module. The battery system also includes a suppression system having a suppressant, where the suppression system is configured to provide the suppressant to the battery module to mitigate a thermal runaway event.

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 composition for radiation shielding or range of compositions is disclosed, with which the compositions may be used for a variety of radiation shielding applications. With proper adhesive selection and processing, the construction forms an integral bond with the craft as compatible adhesives form strong bonds. This eliminates the potential for delaminating associated with the use of metallic layered shielding. While prior art protects electronics with a direct coating to electronic packages, this approach allows larger equipment systems, such as optics, or spectrometers to be shielded.
