Abstract

The invention provides a battery module modeling method and device, terminal equipment and a storage medium, and the method comprises the steps: carrying out physical modal test of a battery cell in a battery module, obtaining the real modal of the battery cell, building a finite element model of the battery cell, and obtaining a first finite element model; adjusting battery cell material parameters in the first finite element model until the first finite element model meets a first preset convergence condition; establishing a finite element model of the battery module according to the parameters of each structural component except the battery core in the battery module and the adjusted battery core material parameters; and adjusting material parameters of simplified blocks in the finite element model of the battery module until the finite element model of the battery module meets a second preset convergence condition, and outputting the converged finite element model of the battery module to obtain a battery module simplified model. According to the invention, the simplification of the battery module model can be realized.

Description

technical field [0001] The present application relates to the field of battery module technology, and in particular to a battery module modeling method, device, terminal equipment and storage medium. Background technique [0002] The modal simulation method of the battery module is an experimental process method carried out in a computer or an environment composed of simulation equipment by using the battery module model instead of a real physical object. With the continuous development and progress of simulation technology, the automotive industry, especially new energy vehicles, is increasingly using simulation methods to replace the real experiment process in order to reduce the number of tests and reduce the cost of tests. [0003] In the process of battery module modeling, in order to improve the efficiency of battery pack simulation, the battery module model needs to be simplified before battery pack simulation, so as to improve the efficiency of battery pack simulatio...
