Patent ID: 8247107

Claim:
A battery pack comprising: a secondary battery including a positive electrode and a negative electrode; a first protective circuit board electrically connected to the battery; a second protective circuit board electrically connected to the first protective circuit board; and at least one conductive plate coupled to a surface of the first protective circuit board and a substantially co-planar surface of the second protective circuit board, wherein the at least one conductive plate includes a body having bending regions, and the battery pack further includes a soldering portion for coupling the first protective circuit board and the second protective circuit to each other by soldering at least portions of the bending region to the first protective circuit board and the second protective circuit board, and wherein a distance from the lower surface of each conductive plate and the upper surface of the conductive plate spaced apart from the lower surface by the existence of the bending regions is within a range of 150 to 250% of the thickness of the conductive plate.
