Abstract

A battery module according to an embodiment of the present disclosure includes a cell cartridge assembly including at least one battery cell and a plurality of stacking cartridges configured to respectively accommodate the at least one battery cell and arranged in layers in a height direction; and a sensing assembly mounted on at least one side of the cell cartridge assembly and configured to sense electrical characteristics of the at least one battery cell. Each of the stacking cartridges includes a bolt-assembling finger protruding from at least one corner area beyond other corner areas, and the bolt-assembling finger includes an assembly guide unit provided in a slot form. The sensing assembly includes a sensing assembly body provided in the form of a plate-shaped structure and having a plurality of sensing members mounted thereon, and an assembling plate integrally formed with the sensing assembly body and capable of being inserted into the assembly guide unit of the bolt-assembling finger.

Description

technical field [0001] The present disclosure relates to a battery module, and more particularly, to a battery module having a stable fixing force between components. [0002] This application claims priority from Korean Patent Application No. 10-2015-0124321 filed in Korea on Sep. 2, 2015, the disclosure of which is incorporated herein by reference. Background technique [0003] Recently, rechargeable secondary batteries have been widely used as energy sources for wireless mobile devices. Furthermore, secondary batteries have attracted attention as a power source for electric vehicles (EV) and hybrid electric vehicles (HEV), which have been proposed to address air pollution caused by conventional gasoline and diesel vehicles using fossil fuels. [0004] Small mobile devices use one or a few battery cells per device, while medium or large devices (such as automobiles) use a medium or large battery module in which a large number of battery cells are electrically connected, o...
