Problems solved by technology

[0007] However, in the conventional battery module, when cell bulging occurs at the battery cells, due to uneven pressure due to the pressure plate including such an embossed type structure, pressure may be generated between the battery cells. deviation
[0008] If cell swelling occurs in conventional battery modules, the structural stability of the battery module is weakened due to pressurization deviation due to the pressure plate, and the life performance of the battery is also deteriorated

Abstract

A battery module according to an embodiment of the present invention comprises: a battery cell assembly comprising a plurality of battery cells stacked on each other; end plates provided on front and rear sides of the battery cell assembly, respectively; buffer plates provided on the end plates and respectively provided on a front side and a rear side of the battery cell assembly; and a pressure plate disposed between the buffer plates and between the battery cells of the battery cell assembly, in which each of the buffer plates and the pressure plate has a front surface and a rear surface having a flat shape in a view along a front-rear direction of the battery cell assembly.

Description

technical field [0001] The present disclosure relates to a battery module and a battery rack and an energy storage system including the battery module. [0002] This application claims priority from Korean Patent Application No. 10-2020-0008780 filed in Korea on January 22, 2020, the disclosure of which is incorporated herein by reference. Background technique [0003] Secondary batteries are highly applicable to various products and exhibit excellent electrical characteristics such as high energy density, and such secondary batteries are often used not only in portable devices but also in electric vehicles (EV) or hybrids driven by power sources Powering Electric Vehicles (HEV). Because the secondary battery can greatly reduce the use of fossil fuels and does not generate by-products during energy consumption, the secondary battery is attracting attention as a new energy source for improving environmental friendliness and energy efficiency. [0004] Currently widely used ...
