TL;DR——三句话

  • W. L. Gore & Associates launched GORE MultiVent, integrating pressure equalization, moisture protection and thermal-runaway evacuation in a single pack-vent part. (S1)
  • The vent is built on technology Gore acquired from Vernay Laboratories in 2026, combining a Gore membrane with Vernay valve hardware. (S1)
  • MultiVent is rated at 1,200 L/h airflow at 100 mbar, sub-20 mg/day moisture ingress in Gore lab tests, and 50 L/s at 180 mbar evacuation when the larger valve opens at 50 mbar. (S1)

Reported by Charged EVs on 2026-10-19. Summarized and analyzed by XAIPART Editorial.

What happened

W. L. Gore & Associates has launched the GORE Battery Vents – MultiVent Series, an integrated vent aimed at EV and energy storage battery packs that the company says combines pressure equalization, moisture protection and thermal-runaway evacuation in a single device.S1

MultiVent is positioned as an alternative to the typical pairing of a dual-stage vent, a separate evacuation valve and a desiccant, with Gore arguing that every extra component adds validation work, sealing surfaces and moisture paths that can drive corrosion, sensor faults and warranty costs.S1

The vent integrates technology that Gore acquired from Vernay Laboratories in 2026, joining a Gore microporous membrane with Vernay's valve hardware into a part that mounts through a single opening in the pack wall and uses two valves plus the membrane.S1

During normal operation one valve opens at a defined pressure and, combined with the membrane, lets the pack breathe while blocking water, dust and debris. Gore specifies airflow of 1,200 L/h at 100 mbar and rates moisture ingress, in company lab tests at 22 °C and 50 % relative humidity, at less than 20 mg per day.S1

For thermal-runaway gas evacuation the larger valve opens at 50 mbar, delivers 50 L/s at 180 mbar and then reseals the housing. Gore adds that MultiVent holds up after standard automotive aging tests and resists typical thermal-runaway temperatures.S1

Background timeline

  2. – Gore publicly launched the GORE Battery Vents – MultiVent Series. [S1]

XAIPART take

Technical impact

Consolidating breath, desiccant-grade moisture blocking and thermal-runaway gas evacuation into one housing reduces bill-of-materials count on the pack wall, trims sealing interfaces and removes the failure mode of a saturated desiccant cartridge. XAIPART analysis

The 1,200 L/h at 100 mbar figure, paired with a 50 mbar trigger on the larger valve and 50 L/s at 180 mbar evacuation flow, gives designers a single vent that is claimed to handle both slow pressure cycling and the burst regime seen during cell venting events. XAIPART analysis

Market impact

Combining Vernay valve know-how with Gore membrane IP targets the same single-component vent slot competitors such as TroGroup, Festo and several Asian vent specialists occupy, which can pressure incumbent pricing on multi-part vent stacks. XAIPART analysis

For procurement, fewer SKUs per pack and removal of the desiccant service interval simplify the PPAP documentation list, supplier audits and incoming-inspection routines on EV and stationary storage lines. XAIPART analysis

Action

Design engineers should request the MultiVent datasheet and the SAE/USABC-equivalent abuse-test report from Gore, then map the 50 mbar / 180 mbar ratings into the pack CFD and cell-venting propagation model before replacing an existing two-vent architecture. XAIPART analysis

Buyers should benchmark this single part against current vent-stack unit cost, total opening count per pack, and the lifetime cost of periodic desiccant service to size the landed savings. XAIPART analysis

XAIPART Forecast

If a Tier-1 EV pack program publicly redesigns its vent architecture around GORE MultiVent – MultiVent Series and ships in series before 2027-09-30, XAIPART expects the consolidated-vent category to capture more than 25 % of new North American EV pack vent designs by 2028-12-31; if no such reference design is named by that date this forecast is wrong. XAIPART analysis

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Key numbers (1,200 L/h, 20 mg/day, 50 mbar, 50 L/s at 180 mbar) are sourced from Gore-controlled lab testing and a single trade-press write-up; no independent third-party verification is provided in the source.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
