Disclosed herein is a middle- or large-sized battery module comprising: a battery cell stack including a plurality of battery cells or unit modules electrically connected with each other; a first module case constructed in a structure to entirely surround one side end of the battery cell stack and to partially surround the upper and lower ends of the battery cell stack; a second module case coupled with the first module case, the second module case being constructed in a structure to entirely surround the other side end of the battery cell stack and to partially surround the upper and lower ends of the battery cell stack; a sensing member mounted to the first module case or the second module case; and a battery management system (BMS) mounted to the first module case or the second module case.

Middle or large-sized battery module

Disclosed herein is a voltage sensing member for sensing the voltage of battery cells constituting a battery module, the voltage sensing member comprising: (a) a pair of supporting parts mounted to the bottom of the battery module at regions (the front and rear parts of the battery module) corresponding to electrode terminal connections of the battery cells; (b) connection parts for electrically connecting the supporting parts to a connector; (c) a plurality of conductive sensing parts protruding upward while one end of each is connected to the corresponding support part and the other end of each is elastically connected to electrode terminals of the battery cells; and (d) the connector mounted on the front part or the rear part of the battery module for transmitting the sensed voltage of the battery cells to a battery management system (BMS).

Voltage sensing member and battery module employed with the same

A battery disconnect unit for selectively coupling a battery pack to a load is provided. The unit includes a base portion that holds first and second contactors, a pre-charging relay, and a charging relay, thereon. The unit further includes a circuit board having first, second, third and fourth bus bars disposed thereon. The first and second bus bars are coupled to first and second terminals, respectively, of the first contactor. The first bus bar is further coupled to the battery pack, and the second bus bar is further coupled to the load. The third and fourth bus bars are coupled to third and fourth terminals, respectively, of the second contactor. The third bus bar is further coupled to the battery pack, and the fourth bus bar is further coupled to the load.
