POWER STORAGE SYSTEM AND ABNORMALITY SIGN DIAGNOSTIC SYSTEM
To provide a power storage system for obtaining data for suppressing unexpected stop of the power storage system, etc.SOLUTION: A power storage system 1 is a power storage system including a first power storage device provided in a construction machine and an abnormality sign diagnostic device 100 making an abnormality sign diagnosis of the first power storage device. The abnormality sign diagnostic device is characterized by calculating an actually measured deterioration state that is an index value indicating a deterioration state of the first power storage device 10 by using operation information on the first power storage device, calculating an estimated deterioration state that is an index value of the same type as the actually measured deterioration state by using past operation history information on the first power storage device, calculating a comparison result between the actually measured deterioration state and the estimated deterioration state relative to the first power storage device, calculating a comparison result between the actually measured deterioration state and the estimated deterioration state relative to a power storage device provided in each of a plurality of construction machines other than the construction machine, and diagnosing a sign of an abnormality of the first power storage device by determining a gap between the respective comparison results.SELECTED DRAWING: Figure 3
【課題】予期せぬ蓄電システムの停止等を抑制するためのデータを得る蓄電システムを提供する。【解決手段】蓄電システム１は、建設機械に設けられる第１蓄電装置と、第１蓄電装置の異常予兆診断を行う異常予兆診断装置１００と、を有する蓄電システムであって、異常予兆診断装置は、第１蓄電装置１０の稼動情報を用いて、第１蓄電装置の劣化状態を示す指標値である実測劣化状態を算出し、第１蓄電装置の過去の稼動履歴情報を用いて、実測劣化状態と同種の指標値である推定劣化状態を算出し、第１蓄電装置に対する実測劣化状態と推定劣化状態との比較結果を算出し、当該建設機械以外の複数の建設機械のそれぞれに設けられる蓄電装置に対する実測劣化状態と推定劣化状態との比較結果を算出し、これら各比較結果間の乖離を判定することで、第１蓄電装置の異常の予兆を診断することを特徴とする。【選択図】図３
