The testing and evaluation of energy storage devices is an important stage in the development chain for automotive applications. Due to the range of challenges involved a significant number of attributes must be investigated. Beside standard tests the facilities available within the Fraunhofer Battery Alliance enable specialized and highly scientific tests on specific topics, on a cell, module and system level.
