Problems solved by technology

[0010] As mentioned above, the existing contact method is point contact, so there is a fundamental problem of low electrical contact reliability
Moreover, when the contact portion A is contaminated by foreign matter, the incidence of poor electrical contact increases.
[0011] In addition, when manufacturing and producing CMA, the contact unit 40 made of springs as described above is accompanied by operations such as bolting, welding, riveting, etc., so it becomes a major factor hindering the assembly process, thereby reducing productivity and operating efficiency. question

Abstract

The present invention relates to a contact pad for sensing the voltage of a cell module assembly, which is electrically connected to a voltage sensing module for measuring battery cell voltage of the cell module assembly constituted by one or more battery cells, and which electrically contacts an electrode of the battery cell. The contact pad is made of organic elastic conductive materials. As the contact pad which electrically contacts the battery cell is made of conductive organic elastic materials, the reliability of the electrical connection between battery cells is improved, and faulty operation of the contact pad with regard to the cell module assembly caused by foreign substances, physical impact applied from an external source, or the like is effectively prevented.

Description

technical field [0001] The present invention relates to a contact pad that is connected to an external electrical and electronic module and electrically contacts electrodes of the battery cells for voltage sensing and management of each battery cell constituting a cell module assembly. More specifically, it relates to a contact pad made of a conductive organic elastomer for improving the reliability of electrical contact with an electrode of the battery cell. Background technique [0002] A cell module assembly (CMA, Cell Module Assembly) refers to an assembly composed of more than one rechargeable and dischargeable battery unit and electrical and electronic modules required for association with a battery management system (BMS, Battery Management System). [0003] The unit module components such as figure 1 As shown, a battery pack 10 composed of more than one battery cell, a component case 20, an electrode 30 of the battery cell, a contact unit 40 contacting the electrode...
