Electric vehicles came to market demonstrating new technologies and new challenges for OEMs and their suppliers. A significant focus of current research and development has been related to the cells’ chemistry, which is improving at a fast pace. In addition to this, new requirements regarding safety and performance are demanded which causes the battery tray to constantly evolve. In this direction, Gestamp defines an innovative steel battery box solution, which can be applied in a wide range of electric vehicle segments.

Four basic requirements have been established for this revolutionary system: High energy capacity, stampings with high formability, simplified assembly process and high safety performance. These four pillars were used to develop the first cell-to-pack concept. The cross members were deleted, allowing more space for additional cells. The enclosures were redesigned taking advantage of extra deep drawing steel alloys. The joining technologies were selected taking into account the process energy input to decrease final distortion and improve final assembly quality.

The new Gestamp steel battery box design achieved an energy storage increase of 15% using the same exterior packaging. Components have simple geometries with a high degree of manufacturability. The body and battery housing work as a holistic system resulting in a high crash performance, lighter weight solution.
