Abstract
In this paper a new proposal of failure zone definition for ultracapacitors is discussed. Such regions of failure are suitably defined in the frequency domain. The ultracapacitor behavior and its possible ageing are characterized via an impedance spectroscopy measurement technique. Results of an experimental analysis are reported, and an investigation of the possible performance degradation as well as of the ultracapacitor lifetime reduction is carried out and discussed in comparison with the common industry approach of failure definition.
