Freudenberg Sealing Technologies, a global developer of engineered sealing solutions, will showcase a portfolio of e-mobility products at this week’s 2017 North American Battery Show in Novi (US). The company will display components that assist with thermal management, power efficiency, friction reduction, weight reduction and compact installation spaces, among others.
Some of the company’s solutions for lithium-ion batteries, for example, include the Curve Gasket, Offset Seals, O-Rings and Large Format Gaskets. As in standard internal combustion systems, these Freudenberg components help reduce friction, emissions and weight in the lithium-ion batteries used electric vehicles. They also offer easy handling and assembly.
Consideration of the unique heat and pressure conditions these components face in E-Mobility applications has prompted Freudenberg to offer them in in a wide range of materials; among them are elastomers that meet strict e-mobility flammability standards.
Product demonstrators at the Freudenberg booth will highlight other e-mobility component offerings including pouch cell fixation elements and the company’s new DIAvent pressure management solution.
DIAvent provides ideal pressure management in large-scale batteries used in electric and hybrid vehicles. DIAvent is made up of multiple layers of a non-woven fabric and an umbrella membrane that provide extremely high gas permeation during normal operation and a reversible, emergency degassing function in case of a cell malfunction.
DIAvent is water tight and oil resistant, meets multiple protection category requirements for dust, water and particles contamination and can be quickly assembled and installed in the battery.
Freudenberg will also display a number of electric motor and inverter and charger solutions at the show.
For electric powertrains, the company’s Energy Saving Seal (ESS) can lower friction by up to 40% in uni-directional applications. Its Low Friction Simmerring Shaft Seal (LFS) reduces friction by as much as 20%. A Simmerring Shaft Seal with a conductive non-woven element saves weight and space, is cost efficient and reduces the risk of a shaft becoming electrically charged and damaging the gearbox. This seal is available in multiple primary sealing lip designs and materials.
Freudenberg’s 2K Plug & Seal offers multiple E-Mobility benefits including a reduction in system weight, a customizable design, complex sealing geometries and chemical bonding between the component’s hard and soft materials that eliminates potential leakage. Encoders, Edge Bonded Seals, Plug and Seal components and Coated Embossed Gaskets round out the options for electric powertrain applications.
Inverter and charger options include Press-in-Place Gaskets, sealing covers, Offset Seals and O-Rings.
As manufacturers continue to pursue E-Mobility systems and designs, our goal is to deliver battery and powertrain solutions and expertise that help propel this industry forward.—Michael Tercheck, Global Market Segment Manager Automotive, Freudenberg-NOK Sealing Technologies
