The development of such an optimized energy storage system requires the most accurate possible knowledge of the power and load data occurring during driving operation. An operational development and testing environment was therefore established at the Fraunhofer LBF for multiphysical testing of the energy storage system. With regard to the installation situation in the subsequent vehicle test carrier, the energy storage system was prepared for integration into the laboratory test environment by means of adapted connection stiffnesses.
The properties of the longitudinal frame support on the body side, developed by the project partner Abt E-line, were also taken into account. In addition to vibration excitation from driving operation and outside temperatures up to +35 ºC, the energy storage system was validated with a transient current profile and analyzed in terms of its performance and temperature behavior.
