Gore launches MultiVent battery vent combining pressure equalisation and thermal runaway evacuation in single component
W. L. Gore & Associates has introduced the GORE Battery Vents MultiVent Series, an integrated vent for EV and energy storage battery packs that equalises pressure, blocks moisture and evacuates gas during thermal runaway. The device delivers airflow of 1,200 L/h at 100 mbar, up to six times that of alternative venting options, and moisture ingress under 20 mg per day at 22°C and 50% relative humidity, less than one tenth that of many dual vents. The vent combines Gore membrane technology with valve technology acquired from Vernay Laboratories in 2026, mounting through a single opening to replace dual stage vents, separate evacuation valves and desiccants.
Why it matters
The integrated design reduces component count, validation requirements and sealing complexity for battery pack designers, potentially lowering warranty costs linked to moisture intrusion, corrosion and sensor faults. Higher airflow performance may allow pack designs with fewer vent points, simplifying procurement specifications for OEMs and energy storage system integrators.
