Claim 8:
9. A battery storage device for an electric vehicle, comprising:
a lower case having a bowl shape with an open top by bending side portions of the lower case in a vertical direction and a space for accommodating a battery module;
an upper case located on an upper part of the lower case, having a bowl shape with an open bottom by bending side portions of the upper case in the vertical direction and a space for accommodating the battery module;
coupling ends being formed by horizontally bending end portions of the side portions of the upper case and the lower case to face each other, and being coupled to seal the spaces for accommodating the battery module inside the upper case and the lower case;
a reinforcing panel disposed between a side of the lower case and the battery module, mounted and fixed to the battery module, and having at least one or more reinforcing members to reduce impact energy in a collision,
wherein the reinforcing panel includes:
a vibration absorption part comprising an inner side facing the battery module, extending along the battery module, and including an elastic material that absorbs impact energy; and
a panel part disposed to face an outer side of the vibration absorption part, coupled to the vibration absorption part through connecting members, extending along the vibration absorption part, and including a rigid material,
wherein the reinforcing panel is mechanically coupled to the battery module at the top of the panel part by fastening members, and
wherein the connecting members do not overlap with the coupling ends of the upper case and the lower case in a horizontal direction.
