The Swiss Battery Technology Center operates the Battery Testing Laboratory together with the BFH Center for Energy Storage in a public-private partnership. The largest battery laboratory in Switzerland for cell and module testing enables start-ups, SMEs or large companies to test their energy storage systems in a complete environment with the help of experts. Together in innovation projects or single runs, the SBTC and the BFH center can test and improve your technologies

Battery Testing Laboratory

Battery cells and modules of all sizes can be tested in the Battery Testing Laboratory. During characterization, the batteries are tested under various conditions such as temperature, charge and discharge currents and depths of discharge. The characterization is the basis for the parameters for the battery management system. In addition to cyclic ageing tests, we also offer the High Precision Coulombic Efficiency method, in which statements on battery ageing behaviour can be made after only 50 to 100 cycles and about one month. Additional information on the physical behaviour of battery cells can be obtained with electrochemical impedance spectroscopy.
