Problems solved by technology

In this case, if the battery module 1 is firmly coupled to the battery pack case 3, it is inevitable to spend a lot of time to maintain the battery module 1
[0009] In addition, in addition to the space occupied by the battery modules 1, the battery pack of this configuration also requires the space occupied by the anti-collision beams 2 arranged between each adjacent battery modules, so there is a loss in energy density.

Abstract

A battery pack, according to one embodiment of the present invention, comprises a pack housing and a plurality of battery modules accommodated in the pack housing, wherein the pack housing is configured such that openings formed on both sides thereof are in communication with each other, and also comprises a plurality of guide grooves, and wherein the battery modules are accommodated in an inner space of the pack housing or are detached from the inner space through the openings by moving along the guide grooves in a sliding manner.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0048650 filed in Korea on April 14, 2017, the disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to a drawer-type battery pack, and more particularly, to a battery pack having a plurality of battery modules with a side panel serving as an impact beam. Background technique [0004] With the development of devices powered by electrochemical energy, the demand for batteries with high energy density is increasing. [0005] In particular, in the case of a battery pack of a vehicle, it is necessary to install an anti-collision beam in order to withstand an impact applied from the outside. However, the space occupied by the anti-collision beam is not small, and the space occupied by the anti-collision beam cannot be used for other purposes. For this reason, it is inefficient in terms of s...
