If the reliability of lithium battery packs can be evaluated and analyzed by modeling and simulation in the design stage, it will not only save time and effort but also allow timely identification and optimization of the defects or weaknesses of the battery systems. Many previous studies have focused on the reliability analysis of batteries.
System reliability model of the battery pack According to a reliability theory and literature report [ 19 ], battery packs with a series connection after a parallel connection performed better than others in practical applications.
This model comprises a multiphysics model of the battery pack, a degradation model of the cells, and a multistate system reliability model of the battery pack. Among them, the degradation model includes a stochastic degradation model and a dynamic response impedance model.
Current, widely accepted methods require incredibly complex models to undergo finite element modeling (FEM) analysis which increases development time. As a consequence of computation time, multi-scale and iterative battery pack design is not typically applied.
