The invention discloses a power supply control method and system for a train and the train, and the power supply control method comprises the steps that when a contact network stops supplying power, a power battery pack is controlled to supply power to a traction unit; when the power battery pack stops supplying power to the traction unit, the DC-DC converter is controlled to boost the direct current from the storage battery, and the boosted direct current is provided for the traction unit. According to the power supply control method for the train, the power supply control system and the train, the running distance of the train on the rail can be effectively prolonged when the overhead line system breaks down. Therefore, rescue cost and safety problems caused by parking of the vehicle on the track are reduced.
本申请公开了一种用于列车的供电控制方法、供电控制系统及列车,该供电控制方法,包括:当接触网停止供电时,控制动力电池包对牵引单元进行供电;当所述动力电池包停止对所述牵引单元进行供电时,控制DC‑DC变换器对来自蓄电池的直流电进行升压,并将升压后的直流电提供给所述牵引单元。根据本申请的用于列车的供电控制方法、供电控制系统及列车,能够在接触网故障时有效延长列车在轨道上的行驶距离。以便行驶到下一站进行救援和维修,减少车辆在轨道上停车产生的救援成本和安全问题。
