To provide an information calculation system that is able to improve the accuracy of deterioration prediction and deterioration diagnosis of a secondary battery after initial use and reuse.SOLUTION: An information calculation system includes a history acquisition unit, a first element deterioration calculation unit, an assumed load acquisition unit, and a second element deterioration calculation unit. The history acquisition unit acquires a battery load history of a used secondary battery. The first element deterioration calculation unit calculates a first element deterioration state of each of the battery compositional elements of the second battery, based on the battery load history and a plurality of deterioration factors related to each battery compositional element. The assumed load acquisition unit acquires assumed load information that is assumed to act on the secondary battery when the secondary battery is used in the future. Based on the first element deterioration states, the assumed load information, and the plurality of deterioration factors related to each battery compositional element, the second element deterioration calculation unit calculates respective future second element deterioration states of the plurality of battery compositional elements of the secondary battery when the secondary battery is used in the future.SELECTED DRAWING: Figure 2

    【課題】初期利用後や再利用時の二次電池の劣化予測や劣化診断の精度を向上させることができる情報算出システムを提供する。【解決手段】情報算出システムは、履歴取得部と第一要素劣化算出部と想定負荷取得部と第二要素劣化算出部とを備える。履歴取得部は、使用された二次電池の電池負荷履歴を取得する。第一要素劣化算出部は、二次電池の各電池構成要素の第一要素劣化状態を、電池負荷履歴と各電池構成要素に関する複数の劣化要因とに基づいて算出する。想定負荷取得部は、将来用途に二次電池が用いられた場合に二次電池に作用すると想定される想定負荷情報を取得する。第二要素劣化算出部は、将来用途に二次電池が用いられた場合における、二次電池の複数の電池構成要素のそれぞれの将来の第二要素劣化状態を、第一要素劣化状態と想定負荷情報と各電池構成要素に関する複数の劣化要因とに基づいて算出する。【選択図】図2
