Zusammenfassung: | To provide a storage battery system capable of determining a decrease in cooling capacity without acquiring a huge amount of pre-evaluation data.SOLUTION: A storage battery system capable of supporting maintenance by estimating a state of a storage battery provided with cooling capacity for a movable body includes a battery temperature recording part for detecting and recording a maximum arrival temperature Tmax on a daily basis by a temperature sensor attached to the storage battery, an environmental temperature recording part for detecting and recording a maximum arrival value Tamb, max of an environmental temperature Tamb in a time zone dating back from a time when the maximum arrival temperature Tmax is detected to a service start time of the day, and a maintenance support information table for storing measures policies associated with the state of the storage battery, determines the degree of a decrease in cooling capacity on the basis of the maximum arrival temperature Tmax, and the maximum arrival value Tamb, max of the environmental temperature Tam, estimates the state of the storage battery on the basis of a determination result of the decrease on the capacity, and can output information selected from the maintenance support information table on the basis of the estimated state of the storage battery.SELECTED DRAWING: Figure 2
【課題】膨大な事前評価データを取得することなしに冷却能力低下の判定が可能な蓄電池システムを提供する。【解決手段】移動体用に冷却能力を備えた蓄電池の状態を推定して保守を支援可能な蓄電池システムであって、蓄電池に付設された温度センサで日別に最高到達温度Tmaxを検出して記録する電池温度記録部と、最高到達温度Tmaxが検出された時刻から当日の運行開始時刻まで遡った時間帯における環境温度Tambの最高到達値Tamb,maxを検出して記録する環境温度記録部と、蓄電池の状態に対応付けられた対策方針が記憶された保守支援情報テーブルと、を備え、最高到達温度Tmaxと、環境温度Tambの最高到達値Tamb,maxと、に基づいて冷却能力低下の程度を判定し、能力低下の判定結果に基づいて蓄電池の状態を推定し、推定された蓄電池の状態に基づいて、保守支援情報テーブルから選択された情報を出力可能とする。【選択図】図2 |
