By combining energy storage equipment, power conversion equipment and electronic equipment, coupled with intelligent operation and maintenance, it helps to simplify installation and operation and maintenance. At present, the storage capacity of energy storage power stations is mostly preset for easy production.

[0003] In the related art, common energy storage power stations are composed of several battery packs, which are packed into energy storage boxes, and then connected in series by power cables to expand the storage capacity of the energy storage power station. The storage capacity of the battery pack is affected by the individual batteries. When the size of the batteries is different, the length, width and height of the battery pack will change. Therefore, the energy storage box containing the battery pack needs to be preset with multiple specifications. The production of energy storage boxes with multiple specifications will make inventory management more complicated. Manufacturers need to predict the market demand for products of different specifications and arrange production and inventory reasonably to avoid product backlog and waste, which increases the difficulty and cost of inventory management.

[0004] In addition, most energy storage boxes are manufactured by welding, and the internal space layout is fixed, which limits the compatibility of the energy storage box with the battery pack, making the configuration and space adjustment of the battery pack inflexible and inconvenient to replace or upgrade the battery pack.
