Abstract :
In order to estimate the field of application for an electrical energy storage, its performance at different operating conditions has to be measured and evaluated. An automated test system has been designed to speed up measurement and to ensure reproducible measurement conditions. The paper focuses on the performance of this test system and on measured data. Based on this data, a battery model of a NiMH cell is parameterized and the obtained results are discussed.
