State of the art electrical energy storage systems for passenger cars and commercial vehicles use one type of cell to set up the module and pack level of the battery. The cell type is selected with respect to the specific application and its electrical and mechanical requirements. The number of cells in parallel and in series is defined by the needed energy, power and voltage within the electric power train. Hybridization concepts on battery system level enhance the degree of freedom towards

Hybridization here means to use two cell types each one optimized for energy content or power capability to be integrated in specific high power and high energy modules. Finally one has the opportunity to scale power and energy performance on vehicle level. Within this paper the companies AVL and Bosch present their results generated within the European project SuperLIB. The focus is on the evaluation and discussion of general pros and cons for this concept including simulation and hardware test results. Within SuperLIB power and energy optimized lithium iron phosphate cells were used to demonstrate the respective concept for hybridization on module level.
