Abstract:
1. A voltage sensing member for sensing voltages of battery cells constituting a battery module, the voltage sensing member including (a) a pair of supporting parts including a front supporting part and a rear supporting part, mounted to a bottom of the battery module at regions at a front part and a rear part of the battery module corresponding to electrode terminal connections of the battery cells, (b) a connection part for electrically interconnecting the front supporting part and the rear supporting part, (c) plate strip shaped conductive sensing parts having one-side ends coupled to the corresponding supporting parts via wires, each of the plate strip shaped conductive sensing parts having a larger contact surface than each of the wires, each of the plate strip shaped conductive sensing parts having a smaller size than the electrode terminal connections, and (d) a connector mounted on the front supporting part or the rear supporting part for transmitting the sensed voltages of the battery cells to a battery control device, wherein the conductive sensing parts are directly connected to the electrode terminal connections of the battery cells in a surface contact manner, and a portion of each of the electrode terminal connections is cut to a size corresponding to the size of each of the plate strip shaped conductive sensing parts.
