The invention provides a rail vehicle dormancy awakening control circuit, a low-voltage control system and a rail vehicle. A rail vehicle dormancy awakening control circuit comprising a storage battery unit, a first contactor, a second contactor, a charger diode, a power supply negative wire, a permanent load, a non-permanent load and an under-voltage protection unit is used for carrying out dormancy awakening operation on a rail vehicle. Compared with the mode of influencing the service life of the storage battery, when the dormancy instruction of the railway vehicle is obtained, the coil of the second contactor loses power, so that the third contact is switched from the closed state to the open state, the power supply of the storage battery to the non-permanent load is cut off, the storage battery is prevented from being over-discharged, and the service life of the storage battery is prolonged. The service life of the storage battery is greatly prolonged.
本发明提供了一种轨道车辆休眠唤醒控制电路、低压控制系统和轨道车辆,通过包括蓄电池单元、第一接触器、第二接触器、充电机二极管、电源负线、永久负载和非永久负载、欠压保护单元的轨道车辆休眠唤醒控制电路对轨道车辆进行休眠唤醒操作,与相关技术中轨道车辆休眠时,可能导致蓄电池过放电,影响蓄电池的使用寿命的方式相比,当获取到轨道车辆的休眠指令时,所述第二接触器线圈失电,使得所述第三触点从闭合状态转到打开状态,断开所述蓄电池对所述非永久负载的供电,以避免所述蓄电池过度放电,大大提高了蓄电池的使用寿命。
