“…Hossain [53] In the model, the ideal voltage source describes the open circuit voltage of the battery, the resistance is the ohm internal resistance of the battery, and the parallel connection of capacitance and resistance describes the polarization of the battery [48]. The Thevenin equivalent circuit model can simulate the dynamic and static characteristics of the battery very well, taking into account the nonlinearity of the battery [49], and the parameters are obtained in a simple way that can be easily translated into a state space model [50][51][52]. However, in the actual operating environment, some model parameters of the battery may change with environmental conditions such as temperature.…”

Remaining useful life prediction is of great significance for battery safety and maintenance. The remaining useful life prediction method, based on a physical model, has wide applicability and high prediction accuracy, which is the research hotspot of the next generation battery life prediction method. In this study, the prediction methods of battery life were compared and analyzed, and the prediction methods based on the physical model were summarized. The prediction methods were classified according to their different characteristics including the electrochemical model, equivalent circuit model, and empirical model. By analyzing the emphasis of electrochemical process simplification, different electrochemical models were classified including the P2D model, SP model, and electrochemical fusion model. The equivalent circuit model was divided into the Rint model, Thevenin model, PNGV model, and RC model for the change of electronic components in the model. According to the different mathematical expressions of constructing the empirical model, it can be divided into the exponential model, polynomial model, exponential and polynomial mixed model, and capacity degradation model. Through the collocation of different filtering methods, the different efficiency of the models is described in detail. The research progress of various prediction methods as well as the changes and characteristics of traditional models were compared and analyzed, and the future development of battery life prediction methods was prospected.
