Abstract: Embodiments of this application disclose a backup power supply method and a related device. The method includes: calculating a battery capacity of a battery based on historical power outage alarm information and historical power consumption information of a station in which the battery is located; if a power outage occurs in the station, calculating a state of charge of the battery based on actual power consumption and power outage duration of the station, and the battery capacity; and sending a current target energy saving level of the battery to the station if it is determined, based on the state of charge, that an energy saving level of the battery changes, so that the station uses a power saving policy corresponding to the target energy saving level.

Abstract: This application relates to the field of communications technologies, and discloses a backup power supply control method, to obtain target power supplying duration of a battery, and determine average power consumption of a communication station (101) within a time period corresponding to the target power supplying duration. Further, a state of charge of the battery is obtained, and actual power supplying duration for the battery to supply power to the communication station (101) is determined based on the state of charge of the battery and the average power consumption. Therefore, an operation mode of a communication device in the communication station (101) may be adjusted, to reduce the average power consumption of the communication station (101) within the time period corresponding to the target power supplying duration.
