Abstract

A battery pack, according to the present invention, comprises a plurality of battery modules arranged in the forward-and-backward direction, and each of the plurality of battery modules comprises a plurality of cylindrical battery cells; a module housing having a plurality of hollows so as to accommodate the cylindrical battery cells to be inserted therein; and a connection plate comprising a mainbody part which is positioned at the top or the bottom of the plurality of cylindrical battery cells and has, on a portion thereof, a plurality of connection terminals electrically contact-connectedto an electrode terminal formed on one of the plurality of cylindrical battery cells; and a connection part which extends to protrude leftwards or rightwards from the main body part, has an extendingand protruding portion which is bent upwards or downwards from the main body part, and has a bent end which is contact-connected to a portion of another connection plate.

Description

technical field [0001] The present disclosure relates to a battery pack including a connection plate, and more particularly, to a battery pack including a plurality of battery modules in a slim design and having improved energy density. [0002] This application claims priority from Korean Patent Application No. 10-2018-0118477 filed in Korea on Oct. 4, 2018, the disclosure of which is incorporated herein by reference. Background technique [0003] Secondary batteries are highly applicable to various products and have electrical characteristics of high energy density. Secondary batteries are applied not only to portable electronic devices but also to electric vehicles driven by electric drive sources, hybrid vehicles, power storage devices, and the like. [0004] Secondary batteries have drawn attention as a new energy source for improving eco-friendliness and energy efficiency because the use of fossil fuels is greatly reduced and no by-products are generated during energy...
