// Characterisation and analysis
The characterisation and analysis of cells, modules and battery systems in regard to properties and behaviour is carried out in different physical domains: electrochemical, electrical, thermal and mechanical. The test objects are stimulated and the signal analysis is performed either in terms of time (e.g. pulse test) or frequency (impedance spectroscopy).
