Secondary battery manufacturing system and method of generating roll map using the same

A secondary battery manufacturing system comprising

• a first controller configured to collect coordinate data of an electrode sheet based on a winding amount signal of the electrode sheet generated by an encoder, wherein the encoder is configured to sense a length of the electrode sheet wound by a rewinder to generate the winding amount signal, and the coordinate data includes coordinates indicating a position on the electrode sheet;
• a measuring device configured to associate the coordinate data with measurement data of the electrode sheet to generate coordinate-related measurement data including the measurement data;
• and
• a server configured to store the coordinate-related measurement data and transmit the coordinate-related measurement data in response to an application programming interface (API) call.
