Protective Shields for Electric Cars
New lightweight solutions to seal against electromagnetic radiation
Freudenberg accompanies technological change in the automotive industry. After all, the future will be driven ever faster by new drive forms. As the world’s leading industry expert with a long-standing and holistic understanding of mobility, we face up to our responsibility to provide our customers with customized products and solutions for a wide range of components in electric vehicles and fuel cell-based vehicles.
Thermal management and print management are currently important topics on the agenda of Freudenberg Sealing Technologies. The results are heat shields specially developed for lithium-ion battery systems, for example. When cells malfunction, they prevent the heat from “leaping over” to neighboring cells. DIAvent has proven itself as an intelligent pressure management solution for large batteries in electric and hybrid vehicles. The patented nonwovens they contain reliably ensure bidirectional pressure compensation even under extreme conditions. In order to generate energy effectively in fuel cell vehicles, we offer special sealing solutions for fuel cell stacks, for example.
Matthew Chapman, President of Automotive Sales and Marketing, Freudenberg Sealing Technologies
As one of the world's leading partners to the automotive industry Freudenberg Sealing Technologies is working on the automotive future.
With its unique product and service portfolio, Freudenberg Sealing Technologies is one of the world’s leading specialists in sealing technology.
Our decades of materials and technology know-how are unparalleled worldwide. But it is only together with the innovative strength of our engineers that Freudenberg Sealing Technologies develops new material and design concepts for tomorrow’s mobility. With our pioneering products, we provide well-founded answers to important challenges in the further development of e-mobility. We counter rising energy densities, for example, with intelligent multifunctional solutions in thermal management and functional reliability. Benefit from the high quality and efficiency of our products on your specific path into the mobile future.
Freudenberg Sealing Technologies heat shields are addressed to Lithium battery systems. Current battery system development trends such as increased energy density on the cell and system level, ultra-fast charging, and protection against traffic accidents require new approaches to improving systems safety.
The United Nations has instituted new standards for improved safety in EVs from 2021 and on. Facing this, we see a strong market pull for heat shields placed between the individual cells and/or around modules of a lithium battery. These shields avoid thermal propagation in case of a severe cell malfunction, or “thermal runaway”. Additionally, the thermal insulation of a broken cell protects the neighbored cells and thus avoids a fatal battery explosion.
LESS includes sustainable sealing technology solutions of the future for all vehicle components.
Do you have a question? Would you like an expert consultation on the sealing solution that best meets your requirements? Would you like a concrete offer? We look forward to meeting you.
Fuel cell technology has numerous advantages over battery-drive systems. South Korea and some other Asian countries want to heavily promote their use in the coming decade.
