In this study, a simulation of an electrochemical impedance spectroscopy for lithium-ion batteries was proposed. The electrochemical process was developed from battery electrode kinetics and mass transfer of mobile Li+ ion through negative and positive electrodes and electrolyte. The phenomena used in this process were represented by an equivalent electrical circuit. A mathematical model was designed using the equivalent circuit and its elements which are in fact battery parameters. The parameter values were presented as compared with real experimental impedance result.

Accurately estimating the state of health (SOH) of a lithium-ion battery is significant for electronic devices. To solve the nonlinear degradation problem of lithium-ion batteries (LIB) caused by capacity regeneration, this paper proposes a new LIB degradation model and improved particle filter algorithm for LIB SOH estimation. Firstly, the degradation process of LIB is divided into the normal degradation stage and the capacity regeneration stage. A multi-stage prediction model (MPM) based on the calendar time of the LIB is proposed. Furthermore, the genetic algorithm is embedded into the standard particle filter to increase the diversity of particles and improve prediction accuracy. Finally, the method is verified with the LIB dataset provided by the NASA Ames Prognostics Center of Excellence. The experimental results show that the method proposed in this paper can effectively improve the accuracy of capacity prediction.
