Major Orders From Car Manufacturers: Huge Interest In DIAvent

DIAvent HighFlow unlike anything else in the industry

Since 2017, Freudenberg Sealing Technologies has been developing the DIAvent family, an array of intelligent pressure compensation elements that merge pressure equalization and emergency degassing into a single unit, thereby enhancing electric vehicle battery safety. The range extends from the basic DIAvent light ventilation element to the DIAvent HighFlow, which integrates bidirectional pressure compensation with an emergency degassing function in one component.

DIAvent HighFlow is the only product of its kind in the industry. Freudenberg engineers developed it to balance air pressure variations within the battery housing of an electric vehicle and to provide emergency degassing in case of thermal runaway. The component occupies 50 to 70 percent less space than similar solutions and is lighter due to its innovative UL94-V0-compliant plastic housing. This not only makes it more cost-effective than two separate units but also simplifies installation and reduces supply chain complexity. Moreover, it supports the use of batteries with higher power density, fulfilling the demands for range, performance, and safety in battery-powered vehicles.

“Our intelligent pressure compensation elements offer car manufacturers an efficient way to enhance the safety of electric vehicles,” explains Ulrich Huth, President Automotive Sales at Freudenberg Sealing Technologies. “The product we offer them with DIAvent HighFlow is unparalleled in the industry. Its robust sales growth reflects its outstanding market reception.”
