Claim:
1. A battery module comprising: a plurality of unit cells each having a top surface that defines a plane, a bottom surface and a side surfaces; a plurality of bus bars that electrically connect the plurality of unit cells and extend over the top surfaces of the plurality of unit cells; a positive electrode terminal and a negative electrode terminal that are electrically connected and in contact with two ends of the plurality of unit cells wherein the positive electrode terminal and the negative electrode terminal of each of the plurality of unit cells extend outward from the top surface of the plurality of unit cells; a battery housing accommodating the plurality of unit cells and the plurality of bus bars; and detection terminals that are each electrically connected to the plurality of bus bars, wherein the detection terminals comprise elongate members that extends in a direction perpendicular outward to and upward from the plane of the top surface of the plurality of unit cells when the bottom surface of the plurality of unit cells are positioned on a bottom surface of the battery housing which is positioned on a flat surface and have a first end that contacts the bus bar and a second end spaced from the first end so as to be exposed outside the battery housing, wherein the battery housing comprises a case having an opening formed thereon, and a cover portion that covers the opening wherein the cover portion is planar and is positioned over the top surfaces of the plurality of unit cells so as to cover the top surfaces of the plurality of unit cells, wherein the detection terminals extend outward from the top surfaces of the plurality of unit cells and through the cover portion to be exposed outside by penetrating the cover portion and wherein the detection terminals include an insertion portion that is positioned outside of the cover, a support portion that contacts both an inner and an outer wall of the cover portion of the housing.
