Why Choose VoltaVent®?


Thermal Runaway: Advanced venting technology instantly relieves pressure build-up in the worst-case scenario of a thermal runaway. After the high flow emergency degassing, the valve will reseal to prevent propagation and maintain battery pack integrity.

Moisture and Dust Protection: Achieve superior battery pack integrity with IP68 and IP69K compliance, helping ensure protection against environmental challenges.

Protection Zone: With its unique, patented protection zone, the VoltaVent® can control the pressure in the battery pack in a predefined pressure region. This seals the battery pack in normal operation, only compensating the pressure if it exceeds the predefined limits. This significantly reduces the amount of moisture accumulated in the battery pack.

Pressure Equalization: Compensation for pressure fluctuations that occur during normal operation. For example, due to temperature differences or a change of environment when the vehicle drives over a mountain pass.

Customizable Solutions: Tailored configurations to meet specific requirements, ensuring seamless integration with your vehicle designs and specifications.

Innovative Technology: Leverage patented technology to stay ahead of industry standards and regulatory requirements.

Global Support, Local Expertise: Benefit from Vernay’s extensive global network of design, manufacturing, and service centers, offering localized support with global insights.

Reliability Through End-of-Life Testing: The unique protection zone of
the VoltaVent® allows customers to perform a 100% functional test of the
valve and battery pack integrity.
