Patent number: 8849598Abstract: A method of estimating the internal state of a first electrochemical system for power storage is disclosed. The SoC and the electrochemical impedance are determined for different internal states of a second electrochemical system of a same type as the first electrochemical system being studied. An electrochemical impedance model is then defined as a function of the SoC and of parameters. The electrochemical impedance Z of the system studied is determined and its SoC is estimated using the model applied to electrochemical impedance Z.Type: GrantFiled: September 22, 2011Date of Patent: September 30, 2014Assignee: IFP Energies NouvellesInventors: Remy Mingant, Julien Bernard, Valérie Sauvant-Moynot

Publication number: 20130069660Abstract: The invention is a method for estimating the internal state of a system for the electrochemical storage of electrical energy, such as a battery. For various internal states of batteries of the same type as a battery being analysed, impedance measurements are carried out by adding an electrical signal to the current passing through the batteries. Then, an RC circuit is used to model the impedances. Next, a relationship is calibrated between the SoC (and/or the SoH) and the parameters of the RC circuit using multivariate statistical analysis. A measurement of the impedance of the battery under analysis is carried out which is modeled using the RC circuit. Finally, the relationship of the equivalent electric circuit defined for the battery being analysed is used to estimate the internal state of that battery.Type: ApplicationFiled: February 11, 2010Publication date: March 21, 2013Inventors: Julien Bernard, Arnaud Delaille, François Huet, Jean-Marie Klein, Rémy Mingant, Valérie Sauvant-Moynot

The SoC and the electrochemical impedance are determined for various internal states of an electrochemical system of the same type as the electrochemical system studied. An electrochemical impedance model is then defined as a function of the SoC and of parameters. These parameters are calibrated through adjustment on the electrochemical impedance measurements obtained for the various internal states. The electrochemical impedance Z of the system studied is determined and its SoC is estimated using the model applied to electrochemical impedance Z.Type: ApplicationFiled: September 22, 2011Publication date: March 29, 2012Inventors: Remy MINGANT, Julien Bernard, Valérie Sauvant-Moynot

Publication number: 20110208452Abstract: A non-invasive method and device for determining the electrical impedance of an electrochemical system for electric power is disclosed. The voltage and current are measured at terminals as a function of time, and these measurements are converted to signals dependent on frequency. The signals dependent on frequency are subjected to at least one segmentation. For each segment, a power spectral density of the current signal ?I dependent on frequency and the cross power spectral density of the voltage and current signals ?IV dependent on frequency are determined for each segment. The electrical impedance of the electrochemical system is determined by calculating a ratio dependent on frequency of a mean of the power spectral densities ?I dependent on frequency to a mean of the cross power spectral densities ?IV dependent on frequency.Type: ApplicationFiled: February 4, 2011Publication date: August 25, 2011Inventors: Rémy MINGANT, Valérie SAUVANT-MOYNOT, Julien BERNARD
