System For Manufacturing Secondary Battery And Method For Manufacturing Secondary Battery

Abstract: According to exemplary embodiments, provided is a system for manufacturing a secondary battery. The system comprises: a server configured to store a roll map including defect data indicating a defect of an electrode roll and reference point data indicating a reference point of the electrode roll; a controller configured to load the defect data and the reference point data from the server; and a reference point sensor configured to generate a reference point detection signal by detecting the reference point of an electrode sheet unwound from the electrode roll, wherein the controller is configured to generate reference point detection data on the basis of the reference point detection signal and compare the reference point data with the reference point detection data.
