Freudenberg Sealing Technologies gives Batteries Air

Over the past 50 years, FST has acquired great expertise in the safety and thermal management of batteries. For example, its sealing experts have conceived of a new housing seal that perfectly establishes the crucial pressure equalization needed for electric mobility. Dr. Kritzer presented additional ideas at the 7th European Advanced Automotive Battery Conference (AABC) in Mainz early this year. One example: a special nonwoven fabric that combines the required water impermeability with increased air permeability while offering still more added value as a degassing element. The improved ventilation prevents battery heating. With this and other concepts, he struck a nerve with representatives of the auto industry. The presentation showed that FST has identified an industry need early and can be a valuable development partner. FST recently bundled its electric mobility know-how in a newly formed organizational unit. “Our general approach is to think a step ahead with our customers,” Kritzer said. “We have a great many ideas in reserve and many of them are already patented.” In this way, Freudenberg can team up with automakers to develop complete modules and systems. “We see ourselves as a partner in cooling and safety,” Kritzer stressed.
