1. A module strain estimating apparatus, comprising:
a module information obtaining unit configured to obtain a plurality of numerical information for a battery module; and
a processor configured to:
receive the plurality of numerical information from the module information obtaining unit,
generate a first profile representing a correspondence between a force applied from the inside to the outside of the battery module and a strain of the battery module, and a second profile representing a correspondence between the force and a stress of the battery module based on a preset learning module and the plurality of numerical information,
generate a third profile representing a correspondence between the strain and the stress of the battery module based on the first profile and the second profile, and
estimate the strain of the battery module according to the stress of the battery module based on the third profile.
