A short-circuit current prediction method includes deriving an internal equivalent circuit of a battery that reflects a short circuit condition in a direct current (DC) circuit, derive a first equivalent circuit in consideration of electrical characteristi...

The invention concerns a method that comprises two fundamental steps. The first one is an innovative process of characterization of the energetic efficiency performed during a charging process of an accumulator. Thanks to this process, one derives a series...

An internal resistance measurement device for stacked battery includes an AC power supply part for outputting an AC current to an measurement-object, which includes at least a stacked battery made of a plurality of stacked power generating elements, by bei...

The method involves analyzing a portion of a response spectrum of an electrochemical element (1) to application of an electromagnetic wave in a frequency, so as to determine an indicator of a value of a state parameter of the element, where the frequency r...
