The present invention relates to an electric vehicle battery case and, more specifically, to an electric vehicle battery case in which an electric vehicle battery module is accommodated. The electric vehicle battery case of the present invention can be reduced in length, when crushed by an external shock in the lateral direction of an electric vehicle, in the length direction by means of a plurality of foldable guide grooves inserted in the width direction into the outer peripheral surfaces of a second reinforcing bar extended in length/longitudinally in the width direction of the vehicle, and thus damage to a battery module can be prevented. In addition, the electric vehicle battery case of the present invention allows outdoor air on the front side thereof to flow into the first to third ventilation spaces of the battery module and be discharged through the rear side thereof while the electric vehicle travels, and thus the temperature, having been raised by the battery module, can be induced to be naturally lowered.
