- Purem expands its high-strength steel battery housing into Europe targeting scalable EV production.
- A multi-company consortium is developing lightweight stainless-steel designs to improve safety and reduce costs.
Expanding its electrification footprint, Purem by Eberspaecher is introducing its advanced battery housing solution to the European market, marking a strategic step in strengthening its presence in the electric mobility ecosystem. The company’s high-strength steel design, already gaining traction in Asia, is engineered to meet evolving safety and cost requirements for next-generation electric vehicles. By leveraging proven material expertise and scalable manufacturing capabilities, Eberspaecher Group aims to position itself competitively in Europe’s rapidly growing EV sector.
Consortium-driven innovation in battery housing development
To accelerate innovation, the company has collaborated with multiple industry players to form a consortium focused on developing lightweight stainless-steel battery housings. Partners such as Sphere Energy, Bertrandt, the Tillmann Group, Reinert, Baosteel Lasertechnik, and 3M are contributing specialized expertise across design, materials, and manufacturing processes. This collaboration enables the creation of robust yet lightweight structures that eliminate the need for additional corrosion protection, improving durability while maintaining cost efficiency in mass production.
Engineering approach focused on safety and efficiency
The consortium’s concept study emphasizes structural integrity through advanced profiles and reinforcement techniques, ensuring crash resistance without significantly increasing weight. Stainless steel is being explored as a core material due to its inherent corrosion resistance and mechanical strength, allowing simplified designs and reduced lifecycle costs. This approach aligns with broader electric vehicle safety requirements, where battery enclosures must withstand impact scenarios while protecting critical components and maintaining thermal stability under demanding operating conditions.
Production scale and market expansion strategy
The high-strength steel battery housing solution has already been introduced in Asian markets, where demand for electric vehicles continues to rise sharply. Production volumes in China are projected to exceed 100,000 units annually starting from the second half of 2026, demonstrating strong scalability and market acceptance. This established production base provides a solid foundation for expansion into Europe, where regulatory pressure and electrification targets are accelerating the adoption of advanced battery technologies.
Upcoming showcase at key industry event
The company plans to present its latest battery housing innovations at the Advanced Automotive Battery Conference Europe in Mainz, Germany, scheduled from May 18 to 21, 2026. This platform will enable Purem to demonstrate its engineering capabilities and engage with key stakeholders across the EV value chain. Participation in such events highlights the company’s commitment to innovation and reinforces its strategic focus on delivering high-performance solutions tailored to evolving market needs in the global EV battery technology landscape.
