The battery laboratory is currently equipped with two Keysight SL1007A cell testers, a Keysight SL1001A module tester, two Binder temperature cycling chambers (MK 115 and MK 720), and a Keysight SL1010A BMS tester. In addition, two contact systems, the KSR-150 and KS-600-14C from Voltavision, have been acquired, enabling measurements on cylindrical, prismatic, and pouch cells under reproducible conditions. Detailed information on the individual devices and their technical specifications can be found in the following figures and tables.
