Abstract
An apparatus for predicting a degree of deformation of a battery module, caused by swelling of a secondary battery. The battery module includes at least one secondary battery in a module case. The apparatus includes a cell evaluation module configured to derive a relationship between a thickness change amount and a reaction force for a single secondary battery; a case evaluation module configured to derive a relationship between a load applied to the module case and a width change amount of the module case; and a prediction module configured to predict a deformation amount of the battery module by using the relationship between the thickness change amount and the reaction force of the secondary battery, derived by the cell evaluation module, and the relationship between the load and the width change amount of the module case, derived by the case evaluation module.
