According to the subway vehicle power-on circuit and the subway train, an under-voltage relay is connected into the power-on circuit of the subway vehicle in series, when a sleep button is pressed down, a first relay is closed and a second relay fails to obtain electric energy emitted by a storage battery, it is determined that the storage battery is under-voltage, and at the moment, the under-voltage relay is closed; the metro vehicle enters the sleep mode, the defect that the service life of the storage battery is affected due to serious feed of the storage battery caused by the fact that the storage battery still works under voltage is overcome, and the service life of the storage battery in the metro vehicle is prolonged.
本申请提供了一种地铁车辆上电电路和地铁列车,通过将欠压继电器串入地铁车辆的上电电路中,在按下休眠按钮后第一继电器闭合后第二继电器未能得到蓄电池发出的电能时,确定蓄电池欠电压,此时欠压继电器闭合,地铁车辆进入休眠模式,避免蓄电池欠压时仍然工作造成蓄电池严重馈电而影响蓄电池使用寿命的缺陷,延长了地铁车辆中蓄电池的使用寿命。
