[0002] Base stations are public mobile communication base stations, and their main function is to connect mobile devices in an area to the Internet or to exchange mobile communications. Therefore, base stations need to work all the time, otherwise the Internet and communications will be interrupted. In order to ensure the normal operation of base stations, energy storage battery cabinets will be set up in the base stations to avoid the need to rely on energy storage batteries to power the equipment in the base stations when the external power is off, so as to ensure the normal operation of the base stations. There is temporal and spatial unevenness in the power consumption of the power grid. For example, when the power grid load is large near factories or in summer, the power supply of the base stations will not be timely, and energy storage battery packs are needed to supplement the power supply. However, the existing battery cabinets are fixed structures, and the internal space cannot be changed. When battery packs need to be added, new battery cabinets can only be added, and the new battery packs need to be connected one by one, which is inefficient; when the consumption in a certain area is large, the battery cabinets cannot be transported.
