Claim Text:
1. A battery pack comprising: a housing having an opening; a plurality of batteries mounted within the housing so that an upper surface of the plurality of batteries are positioned proximate the opening, wherein each of the plurality of batteries include at least one tab positioned adjacent the upper surface of the battery and wherein the batteries are arranged in a first and second columns of batteries; a cover that is positioned on the housing so as to be adjacent the opening wherein the cover has a plurality of penetration openings; a plurality of bus bars electrically coupled to the at least one tab of the batteries so as to connect the tabs of at least two aligned batteries that extend through penetration openings in the cover, wherein the plurality of bus bars have an upper surface that is substantially planar and include a tab that has an upper surface that is substantially planar with the upper surface of the bus bar that extends in a first direction from the tabs of the at least two aligned batteries in the first column and in a second direction opposite the first direction in the second column such that the tabs of the first column extend toward the tabs in the second column in a space between the first and second columns; a sensing circuit board that has a planar upper surface and a planar lower surface disposed on the plurality of bus bars so that the sensing circuit board receives electrical signals from each of the plurality of batteries wherein the sensing board is mounted on the tabs of the plurality of bus bars of the first and second columns of batteries and is positioned in the space between the first and second columns so that the planar lower surface is positioned on the planar upper surface of the tab and is secured thereto via fasteners that extend through the sensing circuit board and the tabs and so that the plurality of bus bars are not covered by the sensing circuit board, wherein the cover includes a plurality of supports so that the at least one tab of the batteries is positioned on the supports, the plurality of bus bars have “∩” shape so as to enclose each of the plurality of supports and the at least one tab of the batteries.
