摘要： A battery pack may be easily discharged to the outside of the battery pack using gas channels disposed in an upper pack housing and a sidewall frame of a lower pack housing. Accordingly, it is possible to delay the spread of high-temperature gases or flames between battery cells accommodated in the battery pack. In addition, a battery pack includes a gasket, thereby preventing gases and flames from spreading between battery assemblies, and a lower pack housing includes a unit frame assembly including unit frames, which allows a bottom area of the battery pack to be freely expanded.

摘要： A vehicle battery pack included in a vehicle includes a battery module, vaporized gas release valves, a coupling duct, and a detection sensor. The battery module includes battery cells and partitions. The partitions are arranged between the battery cells in an arrangement direction of the battery cells, include a heat insulator, and are filled with a cooling solvent. The vaporized gas release valves operate by an increase in pressure associated with vaporization of the cooling solvent in the partitions and release a vaporized gas generated by the vaporization from the partitions. The coupling duct couples the vaporized gas release valves. The detection sensor detects a release of the vaporized gas through the vaporized gas release valves.

摘要： Methods and systems are provided for a battery system which comprises a plurality of battery cells housed inside a battery enclosure of a battery pack, a venting system, and a suppressing agent. The venting system comprises a dual-staged venting valve that equalizes pressure during normal operation of the battery system and a vent valve that opens to relieve pressure during a high pressure or temperature event. The suppressing agent is released into the enclosure of the battery pack to reduce further reactions by removing or limiting oxidants within the battery pack. A solenoid is coupled to the dual-staged venting valve and seals the dual-staged venting valve following release of the suppressing agent, allowing for the suppressing agent to remain in the enclosure for a longer period of time in order to provide increased mitigation of future thermal events in the battery enclosure.
