The handover condition may be: and when the electric equipment runs to a normal running state, the second power supply is switched to supply power.
According to an embodiment of the present disclosure, the reaching of the normal operation state by the electric device in operation S250 may include: the power consumption value of at least one power consumption unit in the electric equipment is in a preset normal power consumption range.

Specifically, after the first power supply is used for supplying power for a period of time, the external power supply needs to be switched back, and the switching condition may also be: and when the power supply time of the first power supply reaches the preset time, switching to a second power supply for supplying power. The first power supply is powered on for peak staggering power supply, and high power at the moment of power on is avoided, so that the external power supply can be switched back after the startup peak is staggered, and the peak staggering time of the cabinet in the machine room can be set to be 3-5 minutes.
