Abstract
Disclosed herein are an equal distribution type connecting member for connecting two or more devices to an external circuit, the connection member including a first connection circuit connected to a connection point of the external circuit, and second connection circuits sequentially connected to the first connection circuit, the second connection circuits being constructed in a structure in which the sectional areas of the second connection circuits are increased and/or the lengths of the second connection circuits are decreased with the increase of the connection distance between the connection point of the external circuit and connection points of the devices, thereby equalizing internal resistances between the connection point of the external circuit and the connection points of the devices, and a middle- or large-sized battery pack including the same. The equal distribution type connecting member according to the present invention is capable of reducing the difference in internal resistances of the circuits, thereby increasing the overall life span of the battery pack. Also, the uniform charging and discharging efficiency of battery modules or battery cells is acquired, and th…
