DYNAMICS FOR SAFETY
For electric mobility to be successful, vehicle weight, safety and reliability play an important role. The Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI, located in Freiburg im Breisgau and Efringen-Kirchen, is working on making future electric cars lighter, safer and more reliable for everyday use and under extreme conditions. For this, our Fraunhofer Crash Center comes to good use, with full-vehicle and component crash test facilities, tomography lab and a battery test stand for destructive dynamic tests of electrical energy storage units. In addition to these research competencies, Fraunhofer EMI has proven expertise in the numerical simulation of dynamic loading processes for materials of all kinds - from steel to CFRP and textile materials.The combination of these capacities allows for the development of innovative vehicle designs and safety concepts for passengers and energy storage units for electric vehicles. The latest high-performance materials for lightweight construction are characterised and improved, and lithium-ion battery processes are analysed, using innovative sensors and the most precise of measurement technology. In addition, scientists conduct safety and reliability analyses (for example, on battery management systems and high-voltage drive-trains), applying lean methodology to determine re-quirements, system design and verification.
