Electric mobility generates diverse challenges for car body development. New solutions must be found to ensure a cost-efficient and ecological electromobility. In several projects ThyssenKrupp Steel Europe has developed body concepts for various electric vehicles. The first project is the ThyssenKrupp Edition of the Future Steel Vehicle from WorldAutoSteel. The project demonstrates the high potential of modern steels and innovative manufacturing technologies. A large part of the body consists of high-strength and hot-formed steels. The aim of the project Streetscooter was the development of a cost-effective body concept for low-volume vehicles. The body structure is made of bent and roll-formed sections. The body panels are made of colored plastic, eliminating the need for paint processes in the car plant. The project InEco is a cooperation with the TU Dresden. The vehicle belongs in the premium compact car segment. The body mainly consists of a combination of various CFRP and steel materials. In other projects funded by the German Ministry of Education and Research ThyssenKrupp is developing multi-material car bodies. The integration of the battery in the vehicle floor places additional demands on the vehicle body. The batteries pose a high potential risk and must be protected by the body. Damage to the battery cells can trigger an immediate or delayed fire or explosion endangering occupants and the environment. Due to the high prices of battery systems, cost-intensive weight reduction measures were worthwhile in the past because the weight reduction meant that battery capacity could be lowered. With battery prices now falling sharply, weight reduction measures for electric vehicles are coming under cost pressure. Steel offers various opportunities for cost-effective weight reduction.
