Battery module and battery pack including same

Abstract

A 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 lower frame which covers a lower surface and both side surfaces of the battery cell stack; an upper frame which covers an upper surface of the battery cell stack; bus bar frames respectively formed on the front and rear surfaces of the battery cell stack; and a connection part which connects the bus bar frames, wherein the connection part is formed of a flexible flat cable (FFC) and is attached to the upper frame.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0160899 filed with the Korean Intellectual Property Office on December 5, 2019, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present disclosure relates to a battery module and a battery pack including the battery module, and more particularly, the present disclosure relates to a battery module including an improved sensing connection and a battery pack including the battery module. 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 powerful energy resource capable of replacing the use of existing products using fossil fuels, and since the secondary battery does not generate by-products due to energy use, it is attracting attention as an environm...

Problems solved by technology

[0013] However, there is a problem in that, due to the figure 1 The cover plate 31 disclosed in is placed above the flexible circuit board 50, so the thickness of the cover plate 31 increases the height of the battery module, and the weight of the module increases

[0014] When the size of the battery module is increased in this way, there are problems in that when the battery module is installed, more installation space is required, and when the battery module is installed in the vehicle, the running performance of the vehicle is deteriorated

[0015] In addition, when the weight of the battery module increases, generally the utilization rate of the battery module decreases, and similarly, when a heavy battery module is installed in a vehicle, the running performance of the vehicle decreases and thus the fuel efficiency decreases
