Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a storage battery-mounted railway vehicle capable of suppressing deterioration of a storage battery and controlling life thereof to be long.SOLUTION: A storage battery-mounted railway vehicle comprises: a power conversion device for converting overhead wire power and supplying DC power to a railway vehicle; a motor for vehicle travel; an inverter for converting DC power into AC power to drive the motor; an auxiliary power source device fro supplying power to on-vehicle electrical equipment using DC power as a power source; a power storage system for charging DC power or supplying power to the inverter; and a control unit for controlling the power conversion device. In the railway vehicle, power used by the railway vehicle in a non-electrified section is supplied from the power storage system. The control unit calculates a target charging rate of the power storage system at the time of entering the non-electrified section on the basis of at least one information of a vehicle load amount expected to be required when the railway vehicle travels the non-electrified section and a battery temperature of the power storage system, and controls the power conversion device according to the calculated target charging rate.SELECTED DRAWING: Figure 4
【課題】蓄電池の劣化を抑制し、長寿命化制御可能な蓄電池搭載鉄道車両を提供する。【解決手段】架線電力を変換して鉄道車両に直流電力を供給する電力変換装置と、車両走行用のモータと、直流電力を交流電力に変換してモータを駆動するインバータと、直流電力を電源として車上電気機器に電力を供給する補助電源装置と、直流電力を充電又はインバータに電力を供給する蓄電システムと、電力変換装置を制御する制御部と、を備え、非電化区間において鉄道車両で使用する電力を蓄電システムから供給する鉄道車両であって、制御部は、鉄道車両が前記非電化区間を走行する際に必要と予想される車両負荷量と、蓄電システムの電池温度の少なくとも何れかの情報に基づいて、非電化区間に進入する時点の蓄電システムの目標充電率を算出し、算出した目標充電率に応じて電力変換装置を制御することを特徴とする。【選択図】図4 |
