ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY MEASURING DEVICE AND METHOD
This abstract first appeared for US patent application 20250004063 titled 'ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY MEASURING DEVICE AND METHOD
Original Abstract Submitted
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.
