Gestamp Battery Box Solutions Debut at China EV Event

Gestamp Showcases Electric Vehicle Battery Box Solutions

Gestamp Automocion S.A. participated in the 2026 World Power Battery Conference and Power Battery Application Ecosystem Exhibition, held in Yibin, Sichuan Province, from September 3 to 6, 2026. At the event, Gestamp presented Gestamp battery box solutions specifically developed for electric vehicles, highlighting two products designed around enhanced safety, high integration, and extended driving range. The showcased technologies included an integrated-frame battery box based on a cell-to-pack integration concept and a three-section scalable battery box built around a scalable enclosure concept. Both solutions combine manufacturing and joining approaches intended to support battery protection, packaging efficiency, sealing reliability, and overall vehicle performance.

Integrated-Frame Battery Box Uses CTP Integration

The integrated-frame battery box from Gestamp Automocion S.A. is based on a cell-to-pack, or CTP, integration concept. The design combines a stamped tray with a one-piece hot-stamped inner frame, creating an integrated structure intended to enhance protection for battery cells. Overlapping sheets are joined through a spot-welding process, supporting the structural design while maintaining an efficient manufacturing approach. The configuration is also intended to improve space utilization within the battery enclosure. According to the showcased solution, these packaging advantages can contribute to extended driving range while also improving assembly efficiency for electric vehicle battery systems.

Three-Section Design Targets Scalable Battery Packaging

The second solution presented by Gestamp Automocion S.A. is a three-section scalable battery box developed around a scalable enclosure concept. It combines cold stamping and hot stamping processes with lap-joint sealing and spot-welded joints. This combination is designed to provide reliable sealing while supporting the enclosure's overall performance requirements. The scalable architecture is also intended to optimize driving range, giving the battery box a packaging approach that can accommodate different requirements while maintaining the stated structural and sealing objectives. Together, the manufacturing and joining processes form the core of the three-section solution shown at the event.

Industry Impact & Outlook

The battery box technologies showcased by Gestamp Automocion S.A. illustrate how electric vehicle battery structures are increasingly being developed around multiple requirements, including cell protection, packaging efficiency, sealing, manufacturing efficiency, and driving range. The integrated-frame approach emphasizes CTP integration and assembly efficiency, while the three-section concept emphasizes scalable enclosure construction and reliable sealing. For automakers and battery-system developers, these characteristics could influence how future electric vehicle platforms balance structural integration with production requirements. The next relevance of these solutions will depend on their application across vehicle programs and how effectively the respective architectures meet specific packaging, safety, performance, and manufacturing needs.
