The invention provides an elevator system power source energy storage type emergency power supply method, device and system. The method comprises the steps that whether the working state of a battery is normal or not is detected; the working state of the battery comprises battery voltage, electric quantity and temperature; starting power is generated by using electric energy stored in a battery and enters a power conversion link; in the power supply conversion link, a conversion mode for converting direct current stored in a battery into three-phase alternating current is selected according to whether a direct current side voltage is greater than an emergency power line voltage effective value or whether a three-phase power supply is needed; and converting the direct-current electric energy into three-phase alternating-current electric energy according to the selected conversion mode. The problem of emergency power supply of the elevator system is solved. The control flow of charging and discharging of the battery in the emergency and non-emergency working states solves the charging and discharging problem of the energy storage link in the emergency power supply device, reduces the maintenance workload of the battery link, and improves the reliability of emergency power supply.

    本发明提供了一种提升机系统电源储能式应急供电方法及装置、系统,该方法包括:检测电池工作状态是否正常;所述电池工作状态包括:电池电压、电量及温度;利用电池储存的电能,产生启动电源进入电源转换环节;所述电源转换环节根据直流侧电压是否大于应急电源线电压有效值或是否需要三相动力电源选择出将电池储存的直流电转换成三相交流电的转换方式;根据选择的转换方式将直流电能转换成三相交流电能。本发明解决了提升机系统应急供电问题。应急和非应急工作状态下对电池充放电的控制流程,解决了应急供电装置中储能环节的充放电问题,降低了电池环节的维护工作量,提升了应急供电的可靠性。
