For example, the product of the real-time discharge voltage and the real-time discharge current may be integrated based on the discharge time to obtain the discharge power. Based on this, the embodiment of the application can estimate the discharge energy of the backup battery through monitoring the discharge voltage, the discharge current and the discharge time, and further estimate the performance of the battery, and provide a judgment basis for battery replacement.

When the controllable power supply receives a discharge instruction of the control unit, the current power supply voltage and current of the communication equipment can be detected and sent to the control unit so as to calculate the current power consumption of the communication equipment, and then the output of the commercial power to the communication equipment can be closed. The controllable power supply detects the power supply voltage and current when the backup battery starts to supply power and sends the power supply voltage and current to the control unit so as to calculate the power supply power of the battery, and then the control unit judges whether the discharging is successful according to the current power consumption of the communication equipment and the power supply power of the battery. If the discharging fails, the control unit ends the battery maintenance process and reports an alarm; if the discharging is successful, the control unit continuously monitors the discharging voltage, the discharging current and the discharging time of the battery through the controllable power supply, compares the discharging voltage with the preset voltage for finishing the discharging of the battery, finishes the discharging of the battery when the voltage of the battery is less than the voltage for finishing the discharging, starts the commercial power to output the communication equipment, and charges the backup battery.
