摘要： Disclosed herein are a bus bar for connecting two or more devices to an external circuit, wherein the bus bar is capable of equalizing internal resistances between a connection point of the external circuit and connection points of the respective devices, and a middle- or large-sized battery pack including the same. The bus bar according to the present invention reduces the difference of internal resistances due to a circuit to allow a battery module having optimized performance and a middle- or large-sized battery pack including the same to be manufactured.

摘要： Disclosed herein is a separation-type connecting member, which electrically connects electrode terminals of unit cells. The connecting member comprises two or more separated connecting bodies, which are connected to the corresponding electrode terminals during the assembly of a secondary battery module, and which are electrically connected with each other by additional conductive members to complete the battery module. The present invention also provides a method of improving the performance of a battery module that is capable of connecting unit cells in parallel with each other to level the voltage of the unit cells while the battery module is manufactured using the connecting member, specifically, before the unit cells are connected in series with each other, or while the battery module is used, thereby minimizing the voltage difference between the unit cells.
