Abstract: A battery pack case prevents moisture from being permeated into a battery pack with an easily assembled structure. The battery pack case includes an upper pack case and a lower pack case that are slidably coupled with each other. The upper pack case includes a coupling protrusion, and the lower pack case includes a coupling groove such that a bonding member is at portion at which the coupling protrusion and the coupling groove come into contact with each other.

Abstract: A method for manufacturing a battery module includes preparing a plurality of cylindrical battery cells having electrode terminals respectively at upper and lower portions, and a module housing having an accommodation portion with a plurality of hollow structures to accommodate the cylindrical battery cells therein; adding an adhesive having thermally and ultraviolet curing properties to an inner surface of the accommodation portion; partially curing the adhesive by applying heat thereto to increase a viscosity of the adhesive; accommodating the cylindrical battery cells in the accommodation portion so that the partially-cured adhesive is between the accommodation portion of the module housing and the cylindrical battery cells; after the accommodating of the cylindrical battery cells in the accommodation portion, applying heat to the adhesive to lower the viscosity of the adhesive; and, after the viscosity is lowered by applying the heat, curing the adhesive by irradiating ultraviolet rays to the adhesive.
