Claim:
1. A device for characterizing at least one element for storing energy via capacitive effect, said device comprising: at least one voltage measurement module comprising at least one means of measurement, called voltage sensor, of the voltage of said element; at least one current measurement module comprising at least one means of measurement, called current sensor, of the current of said element, said voltage measurement and current measurement modules being configured to carry out measurements with response dynamics of the same order of magnitude, i.e. the unit-step responses of said modules are of the same temporal order of magnitude; at least one control means of said measurement modules for carrying out, for each storage element, at least one measurement cycle comprising: at least one means of statistical calculation of a variable relating to each storage element from the measurements taken during at least one measurement cycle by said modules; in which said at least one control means is moreover configured to control said measurement modules so that, for each storage element, said voltage measurement period and said current measurement period overlap in time at least over 70%, of a period, called total period, comprising said measurement periods for said storage element.
