Claims (2)
- 電源装置のバックアップに用いられる蓄電池の放電時間と放電電圧との関係である放電特性を前記電源装置のバックアップ中に推定する蓄電池の放電特性推定方法であって、 前記蓄電池の安定化後以降の放電電圧を、前記電源装置のバックアップ中の少なくとも2つの時点で測定し、前記2つの時点における放電電圧と、設計時に分かっている負荷の大きさにより標準の放電率から推定した放電終止電圧となるまでの放電可能時間に対応する放電終止電圧とを通る2次以上の曲線により前記放電特性を曲線近似して推定することを特徴とする蓄電池の放電特性推定方法。
- 電源装置のバックアップに用いられる蓄電池が放電終止電圧となるまでの残時間を、前記蓄電池の放電特性を曲線近似した結果に基づいて推定する蓄電池の放電残時間推定方法であって、
前記蓄電池の放電電圧を、前記電源装置のバックアップ中の少なくとも2つの時点で測定し、前記2つの時点における放電電圧と、設計時に分かっている負荷の大きさにより標準の放電率から推定した放電終止電圧となるまでの放電可能時間に対応する放電終止電圧とを通る2次以上の曲線により前記放電特性を曲線近似して推定し、前記蓄電池の放電電圧が最後に計測された時点から前記放電終止電圧となるまでの時間を放電残時間として推定することを特徴とする蓄電池の放電残時間推定方法。
