Abstract:
1. A battery pack comprising: a plurality of battery cells each having at least one electrode wherein the battery cells have a width the plurality of batteries comprising a flat portion positioned adjacent the location of an outwardly extending portion of the at least one electrode; a protective circuit module coupled to at least two battery cells wherein the protective circuit module comprises a circuit board that has a width and a length and a PTC device; and a case accommodating the battery cells and the protective circuit module wherein the plurality of batteries are positioned within the case so that the electrodes extend towards each other into a central portion of the case, wherein the two battery cells are disposed on a surface of the case, and the protective circuit module is disposed between the two battery cells on the surface of the case in the central portion of the case so that the circuit board of the protective circuit module is positioned between the two battery cells adjacent the flat portions of the plurality of battery cells so as to extend between the two flat portions such that the length of the circuit board extends parallel to the width of the battery cells and so that the width of the circuit board is interposed between the two battery cells and wherein the PTC device is positioned over the flat portion of at least one of the battery cells.
