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.

摘要： A multi-cell rechargeable energy storage system (RESS) includes a plurality of battery cells organized into battery modules and a first enclosure configured to house the battery modules. The RESS also includes a first vent arranged on the first enclosure and configured to direct air from inside the first enclosure to an environment external to the first enclosure. The RESS additionally includes a second vent arranged on the first enclosure and configured to direct air into the first enclosure from the environment external to the first enclosure. The RESS further includes a phase-change material (PCM) device arranged on the second vent and configured to melt in response to at least one of the battery modules experiencing a thermal runaway event. In combination with the first vent, the PCM generates crossflow ventilation through the first enclosure to cool the battery modules therein and mitigate thermal runaway.

摘要： Presented are thermal management systems with passive quenching sacks for cooling battery assemblies, methods for making/using such systems, and vehicles equipped with such systems. A passive thermal management (PTM) system is presented for cooling a battery assembly, such as a traction battery pack with a battery case containing stacked battery cells. The PTM system includes a fluid container that mounts inside the battery assembly, interposed between the battery case and battery cells. The fluid container stows therein a dielectric coolant fluid and has multiple fluid ports that fluidly connect to the battery cells to dispense thereto the coolant fluid. Thermomechanical plugs, such as wax, film, or smart-material barriers, seal the fluid container ports and passively open (e.g., melt, bend, disintegrate, expand, etc.) at a predefined temperature to thereby unseal the fluid ports such that the coolant fluid is fed from the fluid container into the battery cells.
