The invention discloses an elevator power supply system, an elevator and a power supply control method.A power supply loop of an integrated power supply in the elevator power supply system is connected with a mains supply and a battery, the power supply loop supplies power to a power supply MCU and power utilization parts of the elevator, and the power supply MCU controls the power supply loop to be switched to the battery for power supply when the mains supply is normal and the elevator is idle; when the commercial power is abnormal and a rescue instruction is detected, the power supply loop is controlled to be switched to the battery to supply power to the plurality of electric components, so that the elevator can enter the sleep mode when the elevator is idle, and the power supply is switched to the battery to supply power to the plurality of electric components when the elevator is idle. When the elevator is idle, power supply to the power supply MCU and the calling device is stopped, energy consumption of the elevator in idle is reduced, sleep switching and emergency rescue share one power supply loop, the size of the power supply system is reduced, an independent power supply loop does not need to be arranged for sleep switching and emergency rescue, and the cost of the power supply system is reduced.

    本发明公开了一种电梯电源系统、电梯及供电控制方法,电梯电源系统中一体化电源的供电回路分别与市电和电池连接,供电回路对电源MCU和电梯的用电部件供电,电源MCU在市电正常且电梯空闲时控制供电回路切换至电池供电,使得一体化电源进入休眠模式并停止对除了召唤装置和电源MCU以外的用电部件供电,在市电异常且检测到救援指令时控制供电回路切换至电池对多个用电部件供电,既实现了电梯空闲时能够进入休眠模式,停止对电源MCU和召唤装置以外的用电部件供电,降低了电梯空闲时的能耗,又实现了休眠切换和紧急救援共用一个供电回路,减小了电源系统体积,无需为休眠切换和紧急救援设置单独的电源回路,降低了电源系统的成本。
