Abstract
A device is provided for characterising at least one element for storing energy via a capacitive effect. The device includes a measuring component for measuring the voltage across the terminals of the storing element and another measuring component for measuring the current flowing through the storing element, having response times of the same order of magnitude. The device includes a controller for controlling the measuring component and a calculator for calculating a statistical quantity from the measurements taken. The controller is configured to control the measuring component so that the voltage-measurement period and the current-measurement period overlap temporally by at least 70%, especially 90%, of a total period including the voltage and current-measurement periods. A method is also provided for characterising an element for storing energy via a capacitive effect and to an assembly including at least one element for storing energy via a capacitive effect and a characterising device.
