Claim:
1. A battery module comprising: (a) a unit cell assembly comprising two or more battery cells or unit modules connected to each other in parallel or in series; (b) a left case coupled to a left side of the unit cell assembly, the left case being provided at a left outer side thereof with a first fastening groove extending parallel to a longitudinal direction of the battery module such that a sensing assembly is fastened into the first fastening groove, the left case being provided at opposite ends thereof with second fastening grooves formed parallel to a height direction of the battery module such that the sensing assembly is coupled into the second fastening grooves; and (c) a right case coupled to a right side of the unit cell assembly, an external input and output terminal being oriented to a front of the battery module, the right case being provided at a right inner side thereof with a plurality of fixing grooves formed parallel to a longitudinal direction of the unit cell assembly such that the unit cell assembly is fastened and fixed into the fixing grooves, wherein the left case is provided at a front and a rear thereof with fastening holes for coupling adjacent battery modules formed in a lateral direction of said battery module, wherein the right case is provided at a front and a rear thereof with fastening holes for coupling adjacent battery modules formed in a lateral direction of said battery module, wherein the left case is provided at opposite ends thereof with insertion holes, through which one end of a sensing circuit unit electrically connected to the sensing assembly is coupled to the left case, and wherein the sensing circuit unit transmits sensed voltage to a controller.
