Problems solved by technology

[0013] However, lithium secondary batteries have characteristics in which charging and discharging cannot be performed smoothly and output and charging speed rapidly decrease due to an increase in resistance at low temperatures
Therefore, a lithium secondary battery used in an electric drive device has a problem that the efficiency and output of the secondary battery rapidly decrease when exposed to an external environment at a low temperature for a long time
The temperature non-uniformity among the battery cells 21 may lead to a shortened life of the battery module 10 itself

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; and a sensing assembly located on the battery cell stack, wherein the sensing assembly includes a main body unit located on the battery cell stack, and a module connector connected to the main body unit, and the main body unit is a flexible printed circuit (FPC) or a flexible flat cable (FFC) and includes a hot wire circuit.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0145144 filed with the Korean Intellectual Property Office on November 13, 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 having a heating member and a battery pack including the battery module. Background technique [0004] Secondary batteries have drawn attention as energy sources in various products such as mobile devices and electric vehicles. A secondary battery is a powerful energy source that can replace the use of existing products using fossil fuels, and is attracting attention as an environmentally friendly energy source because it does not generate by-products due to the use of energy. [0005] Recen...
