Separating type connecting member for manufacturing secondary battery module and method for improving battery module performance by voltage leveling

摘要

A method of improving the performance of a battery module having a plurality of unit cells, comprising the steps of connecting two or more of the unit cells, which are connected in series with each other, in parallel with each other, for a predetermined period of time during the manufacture or the use of the battery module, to level the voltage of the unit cells, thereby minimizing the voltage difference between the unit cells.
