Problems solved by technology

[0016] However, in the case of the conventional battery module 10, as described above, the heat transfer path is complicated, so it is difficult to efficiently transfer the heat generated from the battery cells 11
The module frame 30 itself may degrade the heat transfer characteristics, and a thin air layer such as an air gap that may be formed between the module frame 30, the heat transfer member 50, and the heat sink 60, respectively, may also be a contributing factor to deteriorate the heat transfer characteristics.

Abstract

A battery module according to an exemplary embodiment of the present invention comprises: a battery cell stack in which a plurality of battery cells are stacked; a module frame accommodating the battery cell stack; end plates on the front and rear surfaces of the stack of battery cells; and a heat sink located below the bottom of the module frame. And the bottom part forms an upper plate of the radiator. The module frame includes a first module frame protrusion and a second module frame protrusion formed by protruding a portion of the bottom, and the first module frame protrusion and the second module frame protrusion are spaced apart from each other. The welding part of the end plate and the module frame is located between the first module frame protruding part and the second module frame protruding part.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2020-0052266, filed with the Korean Intellectual Property Office on April 29, 2020, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a battery module and a battery pack including the battery module, and more particularly, to a battery module with improved structural stability and a battery pack including the battery module. Background technique [0004] In modern society, with the daily use of portable devices such as mobile phones, notebook computers, video cameras, digital cameras, etc., technologies in the fields related to portable devices have been actively developed. In addition, in order to solve the air pollution of conventional gasoline vehicles using fossil fuels, rechargeable batteries that can be charged and discharged are used as electric vehicles...
