Problems solved by technology

[0016] The above-mentioned process of folding the two ends of the FPCB part 13 and adhering it to the battery cell stack 22 with double-sided tape is difficult to be automated, and requires direct operation by the operator. Product quality deviation due to the proficiency of personnel
In particular, the bent portion 14a should be adhered in such a way that the sensing line formed on the bent portion 14a is connected to the terminal or sensing pin formed on the front side part 11, but since the adhesion process is achieved by manual operation, It is difficult to adhere the curved part 14a at the designated position
In addition, when the bending parts 14a, 15a are incorrectly folded to generate errors, all sensing lines formed at the bending parts cannot be connected to terminals or sensing pins, and a large number of relatively expensive FPCBs are used, thus increasing cost

Abstract

The invention relates to a sensing assembly, a manufacturing method thereof and a battery module. Provided are a sensing assembly and a battery module including the same, having improved economical efficiency in such a manner that a relatively expensive flexible printed circuit board is used in a smaller amount by allowing a relatively inexpensive rigid printed circuit board to replace a portion of the flexible printed circuit board used for a conventional sensing assembly.

Description

technical field [0001] The invention relates to a sensing component, a manufacturing method of the sensing component and a battery module including the sensing component. Background technique [0002] A secondary battery is a device that converts external electrical energy into chemical energy and generates electricity when needed, and is used in various fields such as electronic equipment using electric power, hybrid vehicles, and electric vehicles. [0003] The secondary battery is manufactured in the form of a battery module in which a plurality of battery cells are stacked in one direction, and in order to sense the voltage of the battery cells included in the battery module, cell tabs formed on both sides of the battery cells are connected with wires. The wires connecting the cell pole pieces on both sides have a very thin profile, so additional reinforcement material is required to prevent damage due to vibration. In order to prevent damage due to vibration, it is nec...
