Abstract

A battery module according to one embodiment of the present invention comprises: a battery cell laminate in which a plurality of battery cells are laminated; a module frame for accommodating the battery cell stack; an end plate for covering the front surface and the rear surface of the battery cell stack; a heat sink formed on the bottom of the module frame; and a cooling port for supplying a refrigerant to the heat sink, in which the module frame includes a module frame protrusion formed to extend such that a bottom of the module frame passes through the end plate, and the cooling port is arranged in a shape protruding upward from an upper surface portion of the module frame protrusion.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to Korean Patent Application No. 10-2020-0044876 filed in the Korean Intellectual Property Office on April 13, 2020, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present invention relates to a battery module and a method for manufacturing the battery module, and more particularly, to a battery module with a cooling structure and a method for manufacturing 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 powerful energy resources that can replace the use of existing products using fossil fuels, and since they do not generate by-products from energy use, they are attracting attention as environmentally friendly energy sources. [0005] Recently, with the increasing demand for high...
