Freudenberg Sealing Technologies Is 2022 Automotive News PACE Award Finalist

Freudenberg Sealing Technologies has developed an entire DIAvent family of smart pressure compensation elements which combines pressure equalization and emergency degassing into a single component, making electric vehicles more reliable and economical. The product solutions range from combined pressure equalization and emergency degassing during a worst-case scenario – the thermal runaway of a cell – to the two-way ventilation of oily environments using a DIAvent compensation element uniquely developed for such wet applications.

Developed by Freudenberg engineers to manage the air pressure changes and emergency degassing within the battery housing of a BEV during operation, DIAvent Highflow has no industry equal. It requires 50 to 70 percent less space than competitive pressure regulation and degassing solutions for the same airflow. DIAvent Highflow also offers customers weight saving through its innovative use of a UL94-V0-compliant plastic housing. It is less costly than two separate components, requires less installation effort, addresses supply chain complexity, and supports the industry’s use of higher density batteries to address range, power, and safety requirements in BEVs. DIAvent Highflow will begin serial production by the end of the year with several major automotive manufacturers already committed to its purchase and use.
