Optimized heat Dissipation of Energy Storage Systems

The quality of the heat dissipation from batteries towards the outer casing has a strong impact on the performance and life of an electric vehicle. The heat conduction path between battery module and cooling system is realized in series production electric vehicles by means of paste-like materials. These so-called gap fillers exhibit high thermal conductivity and specific mechanical properties. The aim of an ongoing BMWi research project is to develop a new generation of gap fillers with improved thermal conductivity and reduced density and to qualify them for use in series production.
