Abstract

A battery module according to the present invention may comprise: a cell stack composed of a plurality of secondary batteries arranged in close contact along one direction; a module housing provided to accommodate the cell stack therein; a thermally conductive adhesive provided in a space between the lower end of the cell stack and the bottom surface of the module housing; and a heat dissipating foam formed of a foam having a predetermined volume and a heat dissipating sheet surrounding the foam, and disposed in the space so as to be mixed with the thermally conductive adhesive.

Description

technical field [0001] The present disclosure relates to a battery module including a plurality of secondary batteries, and more particularly, to a battery module having a simple structure for fixing the secondary batteries with light weight and ensuring effective cooling performance. [0002] This application claims priority from Korean Patent Application No. 10-2020-0008779 filed in Korea on January 22, 2020, the disclosure of which is incorporated herein by reference. Background technique [0003] Recently, secondary batteries have drawn attention as power sources for electric vehicles (EV), hybrid electric vehicles (HEV), etc., which are proposed as a solution to air pollution from gasoline vehicles, diesel vehicles, etc. using fossil fuels. [0004] One secondary battery cell or two to four secondary battery cells are used in small mobile devices, but medium and large devices such as electric vehicles require high power and large capacity, and thus use many of them bat...
