Zusammenfassung:To deal with an issue of an existing step controller that the controller cannot suppress variations sufficiently.SOLUTION: A step controller 1 of the present invention is a step controller 1 for a manufacturing step for manufacturing a non-aqueous electrolyte secondary battery, and includes: a cell characteristic prediction unit 11 for acquiring a material parameter showing the quality of the material of the non-aqueous electrolyte secondary battery and a step parameter showing the manufacturing condition of the manufacturing step of the non-aqueous electrolyte secondary battery and calculating a cell characteristic prediction value as a prediction value of the characteristics of a finished non-aqueous electrolyte from the material parameter and the step parameter; and an aim value adjusting unit 12 for adjusting the aim value of the manufacturing condition set for each manufacturing step for at least one of a plurality of manufacturing steps prepared to manufacture the non-aqueous electrolyte secondary battery so that the cell characteristic prediction value becomes closer to a preset ideal value.SELECTED DRAWING: Figure 2 【課題】従来の工程制御装置では、ばらつきの抑制効果が不十分であった。【解決手段】本発明にかかる工程制御装置1は、非水電解質二次電池を製造する製造工程の工程制御装置1であって、非水電解質二次電池の材料の物性を示す材料パラメータと、非水電解質二次電池の製造工程の製造条件を示す工程パラメータと、を取得し、材料パラメータと工程パラメータから完成後の非水電解質の特性の予測値であるセル特性予測値を算出するセル特性予測部11と、セル特性予測値が予め設定される理想値に近づくように非水電解質二次電池を製造するために準備された複数の製造工程の少なくとも1つについて、製造工程毎に設定される製造条件の狙い値を調整する狙い値調整部12と、を有する。【選択図】図2
