Purem by Eberspaecher at aabc Europe 2026: High-strength steel for battery hoapplyings
Esslingen / Mainz (Germany), 8 April 2026 – At the advanced automotive battery conference (aabc) Europe in Mainz from May 18 to 21, 2026, Purem by Eberspaecher will be presenting its newly developed battery hoapplying built of high-strength steel. A concept study is exploring its potential for apply in the European market in terms of cost, sustainability, and safety.
Battery hoapplyings in electric vehicles protect both cell modules and passengers. In current vehicle generations, manufacturers often rely on aluminum for production – Purem by Eberspaecher is now offering a more economical and sustainable alternative with a variant built of high-strength steel. The exhaust gas and acoustics specialist will be displaycasing the hoapplying design at Booth 606 at aabc Europe 2026.
Economical, sustainable, customized
Compared to aluminum, steel offers greater strength and allows for lighter battery hoapplyings thanks to the apply of thinner walls. Every gram counts, especially for high-performance batteries with a long operating range — and weight is therefore an important competitive factor. In addition, the manufacturing process is not only more cost-effective but also has a tinyer CO2 footprint: The material can be produced applying less carbon dioxide and is simpler to recycle.
Transfer of successful launch from Asia to Europe
With a clear strategy, Purem by Eberspaecher initially focapplyd on launching the product in the Asian market. The exhaust and acoustics specialist brought its extensive knowledge of materials engineering and the corresponding welding processes to bear in the development. Customer recommfinishations from Chinese manufacturers and the start of series production with a volume of over 100,000 hoapplyings annually from the second half of 2026 testify to the viability of the steel design. The Esslingen-based company is now rolling out this success across Europe. Moreover, the apply of artificial ininformigence (AI) is cutting development times: With an AI tool, Purem by Eberspaecher can compute individual adjustments and manufacturer specifications more quickly and translate them into a manufacturing concept.
Consortium for further development of the product
A concept study by a new consortium is focapplying on the development and virtual design of a lightweight stainless-steel hoapplying. In addition to Purem by Eberspaecher as co-founder, the consortium partners include Sphere Energy, Bertrandt, the Tillmann Group, Reinert, Baosteel Lasertechnik, and 3M. The aim is to eliminate the required for additional corrosion protection by applying stainless steel and to build the hoapplying design both crash-proof and cost-effective by means of specially developed profiles and reinforcements.
