Abstract: A system that includes a wettable thermal insulator, a phase change material, and a flexible pouch. In the event a thermal event occurs, the phase change material changes from a liquid state to a gaseous state. The flexible pouch is configured to envelope the wettable thermal insulator and the phase change material in the liquid state.

Abstract: A battery pack for a vehicle electrical system includes a casing for receiving one or more battery modules. The battery modules are insertable into a casing of the battery pack by sliding couplers along pairs of rails and are securable to the ends of the rails. After insertion, the rails thermally insulate one battery module from other battery modules coupled to the casing. In some examples, a first stiffness or a first mechanical frequency of the casing with the one or more battery modules inserted may differ from a second stiffness or a second mechanical frequency associated with a body of a vehicle or another component associated therewith by a threshold amount. Additionally, the casing may be configured with vents for venting the hot gases, such as those generated by a battery module in a thermal runaway event.

After insertion, the rails thermally insulate one battery module from other battery modules in the battery pack. Additionally, the battery modules may include a top cover with an insulating material to further thermally insulate one battery module from another battery module. The battery pack may additionally be configured with vents for venting the hot gases, such as those generated by a battery module in a thermal runaway event. Additionally, the battery modules may include a second insulating material disposed between cells and configured to thermally insulate the cells from one another.

Abstract: A battery pack for a vehicle electrical system configured with high-voltage bus bars. A positive bus bar and a negative bus bar may provide power generated by the battery pack to a drive module of the vehicle, to power one or more components of the vehicle. The drive module may additionally couple to high-voltage positive and negative bus bars. The high-voltage bus bars may be configured to provide additional power to the drive module from another battery pack, such as via a battery balance box. Additionally, the high-voltage bus bars may be configured to carry excess power from the drive module to another drive module associated with the vehicle via the battery balance box. The high-voltage bus bars may be configured to de-energize in the event of a thermal runaway or other failure of a battery module of the associated battery pack.
