Disclosed is a battery pack, which includes a battery module assembly; a first end plate and a second end plate respectively installed at the battery module assembly; a first pressure adjustment bar fixed to the first end plate; and a second pressure adjustment bar fixed to the second end plate, wherein the first pressure adjustment bar includes an accommodation space formed so that the second pressure adjustment bar is slidably inserted therein; and a plurality of hook holes formed along a sliding direction of the second pressure adjustment bar, wherein the second pressure adjustment bar has an elastic hook elastically coupled to any one of the hook holes selectively so that when the second pressure adjustment bar slides along the accommodation space, the second pressure adjustment bar is released from any one of the hook holes and then coupled to another one of the hook holes. Since the interval between the end plates is automatically adjusted step by step, the pressure between the battery module assembly and the end plates may be automatically maintained consistently.

Battery pack

Disclosed is a battery pack which has a simple structure, small volume and weight, and efficient cooling performance. The battery pack includes a module assembly including a plurality of secondary batteries, and a plurality of cartridges configured to be stacked with each other and surround an outer circumference of the secondary batteries at an outer side, the plurality of cartridges being at least partially made of thermally-conductive material; and a pack case having an empty space therein to accommodate the module assembly and at least partially made of thermally-conductive material to discharge heat of the module assembly.

A battery module according to an exemplary embodiment of the present disclosure includes at least one battery cell including a cell body and an electrode lead extending from the cell body, a frame cartridge to receive the battery cell in a manner of surrounding a circumference of the battery cell, the frame cartridge having a cell mounting part where the cell body is mounted, and a cell support member interposed between the cell mounting part and the cell body. According to the present disclosure, damage to components caused by vibration may be prevented by suppressing the movement of the battery cell within the frame cartridge, while maintaining convenient assembling performance of the frame cartridge and the battery cell.
