Lithium-ion batteries (LIBs) are usually commonly used in the current electric vehicles. Studying their particular behaviour under mechanical launching, including short circuits, is vital for vehicle security. This paper covers three major topics, (1) a general literature review intended for the state-of-the-art of LIBs, (2) physical cell testing for model validation are performed, wherein the occurrence of short circuits is certainly detected and (3) creating a finite element model (FEM) of an 18650 cylindrical LIB using the many recent testing and simulation techniques. A variety of short-circuit criteria based upon stresses, strains and geometric parameters are implemented inside the simulation and in comparison to the test outcomes. It can be demonstrated that the combination of two geometric criteria, in the radial and axial directions from the cell, is best suited for virtual short-circuit detection in the simulation. Finally, the short-circuit criteria are usually implemented in a post-processing tool that allows prompt short-circuit analysis of tissue various loadings. In the future, this method associated with short-circuit detection will end up being utilized to analyse an assembly of several battery tissues like, for instance, an automotive or maritime battery power pack. Furthermore, the designed method enables mechanical integration with respect to crash safety in vehicles.
