  "textContent": "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.",
