Voltage sensing member and battery module employed with the same
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.
