To achieve high safety by continuously supplying electric power to an auxiliary machine even when switching a plurality of storage batteries mounted on a storage battery-driven railroad train between series-connection and parallel-connection alternately.SOLUTION: A storage battery device comprises: a first shut-off tool that has a plurality of storage batteries and a switching part that switches between series-connection and parallel-connection of the plurality of storage batteries, and that shuts off electric power from a train wire to a DC link; a first electric power converting part that converts electric power from the DC link to electric power for driving a motor; a second electric power converting part that converts electric power from the DC link to electric power for charging the storage battery device; a third electric power converting part that converts electric power inputted from the DC link or the storage battery device to electric power for driving an auxiliary machine; a filter capacitor that is connected to an input side of the third electric power converting part; a second shut-off tool that shuts off electric power supplied from the storage battery device to the DC link; and first and second rectifying parts through which electric power is passed in a direction of the third electric power converting part, from the DC link and the storage battery device, where output points at the third electric power converting part side of the first and second rectifying parts are connected to positive electrodes of the filter capacitor.SELECTED DRAWING: Figure 1

    【課題】蓄電池電車が搭載する複数の蓄電池を直並列に相互に切り替える場合でも、補機へ連続的に電力供給し続けることで高い安全性を実現する。【解決手段】蓄電池装置は複数の蓄電池及び当該複数の蓄電池の直並列接続を切り替える切替え部を有し、電車線から直流リンクへの電力を遮断する第1の遮断器と、直流リンクからの電力を電動機駆動電力に変換する第1の電力変換部と、直流リンクからの電力を蓄電池装置充電電力に変換する第2の電力変換部と、直流リンク又は蓄電池装置からの入力電力を補機駆動電力に変換する第3の電力変換部と、第3の電力変換部の入力側に接続されるフィルタコンデンサと、蓄電池装置から直流リンクへの供給電力を遮断する第2の遮断器と、直流リンク及び蓄電池装置から第3の電力変換部の方向へ電力を通す第1及び第2の整流部とを備え、第1及び第2の整流部の第3の電力変換部側の出力点をフィルタコンデンサ正極側に接続する。【選択図】図1
