Eberspaecher at AABC Europe 2026

Purem by Eberspaecher is challenging the industry dominance of aluminum by introducing a high-strength steel battery housing that offers a more economical and sustainable alternative for electric vehicles. While many manufacturers currently utilize aluminum for its weight properties, this new steel-based architecture achieves superior structural integrity with thinner walls, effectively reducing both production costs and the total carbon footprint without compromising the vehicle's range.

Performance and Sustainability Advantages of Steel
The shift toward high-strength steel provides a distinct competitive edge in terms of material efficiency and environmental impact. Steel inherently offers greater strength than aluminum, allowing for a lightweight design through reduced wall thickness. This is a critical factor for high-performance batteries where every gram influences the vehicle’s operating range. Furthermore, the manufacturing process for steel is significantly less carbon-intensive and the material itself is more readily recyclable, aligning with increasingly stringent European sustainability targets.

From Asian Market Success to European Expansion
This technology arrives in Europe following a successful strategic launch in Asia, where Purem by Eberspaecher leveraged its expertise in materials engineering and specialized welding processes. The viability of the steel design is evidenced by a production volume exceeding 100,000 units annually for Chinese manufacturers starting in the second half of 2026. To streamline the transition to the European market, the company utilizes proprietary artificial intelligence tools to rapidly adapt housing specifications to individual manufacturer requirements, significantly shortening traditional development cycles.

Collaborative Innovation and Virtual Design
To further refine the technology, a consortium including Purem by Eberspaecher, Sphere Energy, Bertrandt, and other industrial partners is conducting a concept study focused on stainless-steel variants. This collaboration aims to eliminate the need for external corrosion protection while ensuring the housing remains crash-proof through specially engineered profiles. This comprehensive approach to battery housing design will be a focal point for the industry at the Advanced Automotive Battery Conference (AABC) Europe in Mainz from May 18 to 21, 2026.
