To improve an operation rate of a railroad vehicle system comprising a plurality of power storage devices and to reduce a maintenance work cost.SOLUTION: A railroad vehicle system of one embodiment comprises: a power supply device 1; a plurality of power storage devices 2; an inverter 3 connecting the power supply device 1 and at least one power storage device 2; an electric motor 4 driven by energy supplied from the inverter 3; and control circuits 5 and 6. Each of the plurality of power storage devices 2 comprises a battery and can output deterioration state information including at least temperature information of the battery to the control circuits 5 and 6. The control circuits 5 and 6 acquire temperature information of the most deteriorated battery when determining that deterioration states of a plurality of batteries have variations by using estimated values of the deterioration states of the batteries on the basis of the deterioration state information of the batteries, and suppress charge and discharge of the batteries when a temperature of the most deteriorated battery is equal to a first temperature threshold or more and less than a second temperature threshold.SELECTED DRAWING: Figure 1
【課題】 複数の蓄電装置を備えた鉄道車両システムの稼動率を向上し、メンテナンス作業のコストを削減する。【解決手段】 実施形態による鉄道車両システムは、電源装置1と、複数の蓄電装置2と、電源装置1および少なくとも1つの蓄電装置2と接続したインバータ3と、インバータ3から供給されたエネルギーにより駆動される電動機4と、制御回路5、6と、を備え、複数の蓄電装置2のそれぞれはバッテリを備え、バッテリの温度情報を少なくとも含む劣化状態情報を制御回路5、6へ出力可能であって、制御回路5、6は、バッテリの劣化状態情報に基づくバッテリの劣化状態の推定値を用いて複数のバッテリの劣化状態にばらつきがあると判断したときに、最も劣化が進んだバッテリの温度情報を取得し、最も劣化が進んだバッテリの温度が第1温度閾値以上であって第2温度閾値未満であるときに、バッテリの充電および放電を抑制する。【選択図】 図1
