Problems solved by technology

Therefore, as the compression pad is repeatedly compressed and shrunk, the elasticity of the compression pad gradually decreases, which causes a problem that it is difficult to properly perform the functions of assembly tolerance absorption and swelling absorption for a long period of time
[0013] In addition, in the process of assembling the battery cell stack into the frame, since the compression pad needs to be inserted and installed between the battery cells of the battery cell stack, the assembly process is complicated and the compression pad must be manufactured and produced separately

Abstract

The present invention relates to a battery module and a battery pack including same, the battery module comprising: a battery cell stack in which a plurality of battery cells is stacked; and a frame member in which the battery cell stack is inserted, wherein the frame member includes a plane part for covering the upper and lower surfaces of the battery cell stack, and a curved part for covering both lateral sides of the battery cell stack, the curved part is formed on both lateral sides of the frame member positioned in the stacked direction of the battery cell stack, and the curved part supports the battery cell stack.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of Korean Patent Application 10-2019-0075826 filed with the Korean Intellectual Property Office on June 25, 2019, the entire contents of which are hereby incorporated by reference. [0003] The present disclosure relates to a battery module and a battery pack including the battery module, and more particularly, to a battery module reducing assembly tolerance and bulge of the battery module and a battery pack including the battery module. Background technique [0004] Secondary batteries have drawn attention as energy sources in various products such as mobile devices and electric vehicles. Secondary batteries are a potential energy source that can replace existing products using fossil fuels, and are attracting attention as an environmentally friendly energy source because they do not generate by-products due to energy use. [0005] Recently, as the demand for a lar...
