Miniaturized battery module and battery pack having the same

A miniaturized battery module comprising:

• a cell assembly (110) configured by assembling a plurality of battery cells (111);
• an upper frame (140) inserted into an outer upper surface of the cell assembly (110), wherein the upper frame comprises a first two opposite sides, and the first two opposite sides are open;
• a lower frame (150) inserted into an outer lower surface of the cell assembly (110) and fastened to the upper frame (140);
• first and second endplates (160a, 160b) fastened to two opposite ends of the cell assembly (110) and configured to fix the plurality of battery cells (140);
• and
• a cover top plate (130) inserted to implement insulation between upper portions of the plurality of battery cells (111) and the upper frame (140);
• wherein,
• at least two or more of the plurality of the battery cells (111) are arranged side by side in the cell assembly (110),
• the upper frame (140) and the lower frame (150) accommodate a semi-module fixing the first and second endplates (160a, 160b), wherein the semi-module comprises theft cover top plate (130) fixing the end surfaces of the first and second endplates (160a,160b) and a connection wire (120) fixed in an inner surface of the cover top plate (130),
• two opposite sides of the cover top plate (130) are each fastened to an end surface of the first endplate (160a) and an end surface of the second endplate (160b), respectively,
• each of the first two opposite sides has a front-view having a “” shape and the upper frame (140) has a cross-section having a “” shape, and
• the cover top plate (130) being a three-dimensional structure, has a cross-section having a “” shape so as to be fastened to the end surfaces of the first and second endplates (160a,160b).
