To appropriately present information on a state and the like of an object.SOLUTION: A control section 10 transmits a measurement result of measurement means for measuring a current and voltage of a secondary battery to a server device. The server device 3 includes: open circuit voltage estimation means for estimating an open circuit voltage of the secondary battery on the basis of the voltage included in the received measurement result; internal resistance calculation means for calculating an internal resistance value of the secondary battery on the basis of the received measurement result; and determination means for determining deterioration of the secondary battery and exhaustion of the secondary battery using the internal resistance value and the open circuit voltage. The server device 3 transmits a deterioration flag representing a determination result of the deterioration of the secondary battery and an exhaustion flag representing a determination result of the exhaustion of the secondary battery to a portable terminal 4.SELECTED DRAWING: Figure 7 【課題】対象物の状態等の情報を適切に提示する。【解決手段】制御部１０は、二次電池の電流及び電圧を測定する測定手段の測定結果をサーバ装置へ送信する。サーバ装置３は、受信した測定結果が含む電圧に基づいて二次電池の開回路電圧を推定する開回路電圧推定手段と、受信した測定結果に基づいて二次電池の内部抵抗値を算出する内部抵抗算出手段と、内部抵抗値及び開回路電圧を用いて二次電池の劣化と二次電池の上がりを判別する判別手段と、を有する。サーバ装置３は、二次電池の劣化の判別結果を表す劣化フラグと、二次電池の上がりの判別結果を表す上がりフラグを、携帯端末４へ送信する。【選択図】図７
