ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY MEASURING DEVICE AND METHOD

The present disclosure relates to an EIS measuring device comprising: an electrical energy storage circuit; an electronic circuit coupled to the electrical energy storage circuit and configured to be coupled to a battery whose impedance is to be measured by the EIS measuring device, a characterization circuit configured to measure an alternative current intended to circulate between the battery and the electronic circuit, and a voltage at terminals of the battery; wherein the electronic circuit is alternately configured in a first mode to pull out electrical energy of the battery and storing the electrical energy pulled-out from the battery in the electrical energy storage circuit, and in a second mode to pull out the stored electrical energy from the electrical energy storage circuit and to re-inject the electrical energy pulled-out from the electrical energy storage circuit in the battery.
