Technology development forms an interface between technical development and production and shapes the manufacturing processes of the future for the mobility of tomorrow. Within body and battery development, the scope of tasks ranges from pre-development topics to the support of current and future vehicle projects to digitalization topics in connection with Industry 4.0. The activities include adhesive, thermal and mechanical joining processes and their process sequences and plant systems. The conflicting tension between low weight and high crash safety leads to innovative material concepts. The mechanical joining processes are the key technologies for the implementation of future-oriented body, battery and cell structures.
