Problems solved by technology

In this way, since the frame structure for protecting the battery cell stack 10 is formed of a multi-part structure of the U-shaped frame 20, the upper plate 30, and the two end plates 40, an assembly process for assembling the individual parts is required, and materials are required for Each part is different and therefore there is a risk that the stiffness of the battery module may be reduced

Abstract

The present invention relates to a battery module having a simplified structure and a method for manufacturing the same, and the battery module according to one embodiment of the present invention comprises: a battery cell stack in which a plurality of battery cells are stacked; a first frame formed of an upper surface and front and rear surfaces to cover the upper surface and front and rear surfaces of the battery cell stack; and a second frame formed by a lower surface and left and right surfaces to cover the lower surface and left and right surfaces of the battery cell stack, in which: a guide protrudes from the first frame and / or the second frame, a guide insertion portion into which the guide is inserted is formed to be recessed in a portion of the second frame and / or the first frame corresponding to the guide, and the first frame and the second frame are coupled to each other by a first coupling portion formed by inserting the guide into the guide insertion portion and a second coupling portion formed by welding an edge of the first frame to an edge of the second frame.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2020-0028573 filed with the Korean Intellectual Property Office on March 6, 2020 and Korean Patent Application No. 10-2021-0024497 filed with the Korean Intellectual Property Office on February 24, 2021, which The disclosure is incorporated herein by reference in its entirety. [0003] The present disclosure relates to a battery module and a method of manufacturing the same, and more particularly, to a battery module having a simplified structure and a method of manufacturing the same. Background technique [0004] Secondary batteries have attracted much attention as energy sources in various products such as mobile devices and electric vehicles. The secondary battery is a potential energy source that can replace the use of existing products using fossil fuels, and since it does not generate by-products due to energy use, it is at...
