STORAGE BATTERY SYSTEM, RAILROAD VEHICLE, DATA SERVER, AND METHOD FOR CONTROLLING STORAGE BATTERY SYSTEM

To provide a technology that allows stable-long-term use of a storage battery while properly keeping a train operation diagram by preventing run-out of power.SOLUTION: A storage battery system includes: a run-out of power prediction part for predicting run-out of power on the basis of storage battery information, meteorological information, and vehicle operation information until the time when a first railroad vehicle starts; and an SOC control condition determination part for determining a control condition of SOC of a storage battery on the basis of a prediction result by the run-out of power prediction part. The SOC control condition determination part controls SOC at the time of first train operation and upper limit SOC of the storage battery.SELECTED DRAWING: Figure 1 【課題】電欠を防止して列車ダイヤを適切に守りつつ、蓄電池を安定的に長期利用することを可能とする技術を提供する。【解決手段】蓄電池システムは、鉄道車両の始発時までの時点において、蓄電池情報と気象情報と車両運行情報とに基づき電欠発生を予測する電欠発生予測部と、電欠発生予測部の予測結果に基づき蓄電池のＳＯＣの制御条件を決定するＳＯＣ制御条件決定部とを備える。また、ＳＯＣ制御条件決定部は、始発時のＳＯＣと蓄電池の上限ＳＯＣを制御する。【選択図】図１
