Whether the subsequent battery life is less than the duration of the storm. If the battery life after power failure is still less than the duration of the storm, disconnect the electrical equipment with the previous priority in order of priority until the battery life after power failure is not less than the duration of the storm. The battery life of the energy storage battery can meet the power demand of the electric equipment that has not been powered off. The computer equipment supplies power to the uncut electrical equipment through the energy storage battery in the energy storage unit to be tested, until the storm warning information indicates that the storm level does not exceed the warning storm level. This power supply control method can ensure that in a storm scene, the energy storage battery can meet the power consumption demand of higher-priority electric equipment, and improves the power supply control efficiency.

Using energy storage batteries with sufficient battery life to charge electrical equipment is conducive to improving power supply control efficiency.

In this embodiment, different power supply control methods are adopted by determining whether the battery life of the energy storage battery is within the duration of the storm. When the duration of the battery life is less than the duration of the storm, the power will be cut off step by step according to the priority of power consumption, so as to ensure that the energy storage battery can supply power to the electrical equipment with higher priority. When the duration of the battery life is not less than the duration of the storm, the energy storage battery is used to supply power to the electrical equipment, so as to avoid the power failure caused by the failure of the mains power supply and the inability to use the solar panel power supply in rainy days, which improves the power supply control. efficiency.
