Abstract:
1. A battery pack comprising: a battery cell; a circuit module coupled to the battery cell, wherein the circuit module comprises a top surface, a bottom surface, and terminals on the top surface; a lead plate comprising an extension region, a side wall region and a bottom region wherein the lead plate extends from the bottom surface of the circuit module to a top region of the battery cell to couple the battery cell to the circuit module wherein the bottom region contacts the bottom surface of the circuit module, the extension region contacts the to region of the battery cell and extends longitudinally outward in a first direction and the side wall region spaces the extension region from the bottom surface of the circuit module a first distance; and a cover coupled to the circuit module and the battery cell to expose the terminals to an exterior, wherein the lead plate comprises a first rib protruding upward from the extension region that contacts a top surface of the battery cell wherein the first rib extends upward from the extension region a second distance less than the first distance and wherein the first rib extends outward in the first direction from the extension region and is positioned on the extension region so that the first rib is exposed from the circuit module in the first direction.
