Abstract

Provided is a secondary battery pack which includes end plates (30) capable of suppressing a deformation caused by an expansion force of unit cells. According to the present invention, there is provided a secondary battery pack including: at least one unit cell including a secondary battery or a secondary battery module; end plates (30) which are disposed on both opposite end sides of the unit cell in a longitudinal direction thereof; a movable wall (60) which is disposed between the at least one end plate (30) and one side face of the unit cell; elastic members (70) which are disposed between the at least one end plate (30) and the movable wall (60) to apply a compression force to the one side face of the unit cell through the movable wall (60); and connecting bars which are configured to connect the end plates (60) with each other disposed on both opposite end sides of the at least one unit cell, wherein the at least one end plate (30) includes: a convex part (33) which is formed thereon so as to protrude in an opposite direction of the one side face of the unit cell, so that, when the movable wall (60) moves to the end plate (30) due to the unit cell being expanded while pressing the elastic members (70), the movable wall (60) is housed therein; and a base part (31) which is disposed at a circumference of convex part (33).
