Problems solved by technology

[0006] Furthermore, when a medium-sized or large-sized battery module is constructed using a plurality of battery cells, or a plurality of unit modules each including a predetermined number of battery cells, a plurality of connections for mechanical connection and electrical connection are required between the battery cells or unit modules. components, and the process of assembling the mechanically connected components or electrically connected components is very complicated
In addition, a space is required for connecting, welding or welding the mechanical connection and electrical connection members, thereby resulting in an increase in the overall size of the system
In the above respects, the size increase of the system is undesirable

Embodiment Construction

[0061] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0062] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted, however, that the scope of the present invention is not limited to the illustrated embodiments.

[0063] figure 1 is a perspective view showing a stack of battery cells including a plurality of unit modules.

[0064] refer to figure 1 , the battery cell stack 100 includes four cell modules 101 and 130 . Two battery cells (not shown) are installed in each unit module 130 . Thus, a total of 8 battery cells are included in the battery cell stack 100 . The electrode terminals of adjacent battery cells are connected in series, and the electrode terminals of adjacent cell modules are also connected in series. The electrode terminal joint 110 is bent in a "["-shaped section to construct a battery cell stack. The outer electrode terminals 120 and 121 of the outermost unit...

Abstract

Disclosed herein is a voltage sensing member constructed in a structure in which linear mounting parts are mounted to supporting parts coupled to the bottom of a battery module, conductive sensing parts are mounted on the mounting parts while the conductive sensing parts are in elastic contact with electrode terminals of battery cells, and the sensing parts are electrically connected to a battery management system (BMS). The voltage sensing member according to the present invention is manufactured by a simple assembly process without using a plurality of members for mechanical coupling and electrical connection. Consequently, the present invention has the effect of reducing the manufacturing costs of the voltage sensing member. Also, the voltage sensing member is maintained in elastic and stable contact when external impact or frequent vibration is applied to the voltage sensing member.; Consequently, the present invention has the effect of performing stable voltage sensing operation. Furthermore, the present invention has the effect of manufacturing a middle- or large-sized battery pack having desired output and capacity using a battery module including the voltage sensing member as a unit body.

Description

technical field [0001] The present invention relates to a voltage detection member mounted to a lower case of a battery module for detecting voltage of a battery cell and transmitting the detected voltage to a battery management system (BMS), and more particularly, to a A voltage monitoring member including a clip-shaped mounting portion protruding upward so that the mounting portion is connected to an electrode terminal joint of a storage battery unit, a conductive spring detecting portion mounted to the protruding portion, a lower end of the mounting portion being connected thereto A plurality of printed circuit boards (PCBs), a connecting portion for electrically interconnecting the front and rear PCBs, and a connector mounted to the rear PCB such that the connector is connected to the BMS. Background technique [0002] Recently, secondary batteries that can be charged and discharged have been widely used as energy sources for wireless mobile devices. Also, secondary bat...
