Abstract: This application disclose example electric energy control methods. When power of a main device is lower than baseline power, an energy storage device is in a charging state and stores remaining electric energy. When power of a main device is greater than the baseline power, the main device receives electric energy output by a power supply device and the energy storage device. To be specific, the energy storage device is in a discharging state and supplies power together with the power supply device to ensure operation of the main device. However, an amount of electric energy stored in the energy storage device is limited. When an amount of the electric energy of the energy storage device is insufficient, the main device is notified to decrease radio frequency power of a preset frequency band of the main device, to reduce a breakdown caused by excessively high power of the main device.

Abstract: This application relate to the field of communications technologies, and disclose 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.
