BATTERY MANUFACTURING SYSTEM AND BATTERY MANUFACTURING METHOD

Embodiments of the present disclosure provide a battery manufacturing system. The system includes a position measuring device configured to generate a sensing signal by sensing a position of an electrode sheet moving between an unwinder and a rewinder, a controller configured to collect position data of the electrode sheet, based on the sensing signal, and a measuring device and/or inspecting device configured to collect measurement data and/or inspection data of the moving electrode sheet and generate position-related measurement data and/or inspection data by relating the position data to the measurement data and/or inspection data. At least one of the controller or the measuring device and/or inspecting device corrects the position data of the electrode sheet, based on a change in an offset length.
