Battery testing technology

In elenia’s Battery Test Laboratory (BaTLa), battery cells and modules of various technologies (Ni-Mn, Li-Ion, Post-Li-Ion) are measured and characterized with regard to their cell characteristics. For this purpose, powerful cell and module testers (charge/discharge units) and impedance spectrometers from various manufacturers, are available in the BaTLa as well as in the diagnostic room of the BLB (Battery LabFactory Braunschweig).
