Description

Technical Field

[0001] The utility model relates to a new type of household energy storage stacked battery system cabinet, belonging to the technical field of energy storage. Background Art

[0002] The battery box system cabinet, as a kind of energy storage battery system cabinet, is widely used in many new energy fields. At present, most of the battery cabinets are formed by installing or fixing multiple battery modules in a cabinet with a shell, thus forming a relatively complete cabinet. For example, first make the cabinet, and then insert the battery modules into the cabinet in the form of a 19-inch cabinet for installation. This increases the installation process and the labor cost of installation workers. In addition, the wiring inside the cabinet is relatively complex. At the same time, the cables and the cabinet need to be customized according to the number of battery modules, which is not conducive to expansion and has low flexibility; in addition, the production time of the cabinet is long and the cost is high. In addition, there is also a kind of stacked battery. Multiple battery modules are stacked together, and then wired externally by plugging and unplugging. A mask is added outside the box. Although the expandability is good, it requires an increase in the installation time of parts and the cost of wiring workers. Content of the Utility Model
