Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to a movable stackable energy storage device. Background Art

[0002] With the profound changes in the global energy consumption structure and the popularization of the concept of green and low-carbon development, energy storage technology, as one of the key technologies to achieve energy consumption and promote energy structure optimization, is receiving more and more attention. In recent years, energy storage technology has developed and matured rapidly, among which stacked energy storage technology has shown great application potential in the field of energy storage due to its advantages such as high energy density and modular design.

[0003] Through modular stacking design, stacked energy storage technology achieves efficient integration and flexible expansion of energy storage units, providing a more flexible and economical solution for energy storage. However, despite the many advantages of stacked energy storage technology, there are still some technical shortcomings in practical applications, which limits its wider application and promotion.

[0004] First, existing movable stacked energy storage devices are relatively large in size and weight, which makes them difficult to carry and install, and also increases the cost of transportation and installation. This limitation is particularly obvious for application scenarios that require frequent movement or installation in different locations.

[0005] Secondly, the cost issue is another important factor that restricts the widespread application of mobile stacked energy storage devices. Due to the high technical difficulty in the research and development, production and manufacturing process, as well as the high cost of raw materials and parts, the price of mobile stacked energy storage devices is relatively high, which increases the difficulty of its promotion in the market and limits its use in some cost-sensitive applications.

[0006] In addition, system integration and control are also challenges faced by mobile stacked energy storage devices in practical applications. Since mobile stacked energy storage devices need to be integrated and coordinated with other equipment (such as solar power generation systems, smart grids, etc.), there may be certain difficulties in system integration and control, which requires energy storage devices to have high compatibility and reliability to ensure the stable operation of the entire system.

Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0019] Figure 1-2 An exemplary structural diagram of a movable stackable energy storage device provided in this application, such as Figure 1 As shown, the movable stackable energy storage device of the embodiment of the present application includes a bracket 1, a tray 2, a connecting plate 3, a cover plate 4 and a universal wheel 5; the bracket 1 includes a plurality of stacked layered frame structures 11, the layered frame structures 11 are interconnected through the connecting plate 3, and the layers are connected by bolts; the layered frame structure 11 is symmetrically fixed with a tray 2 for placing a battery box, and ventilation holes 21 are arranged at intervals on the tray 2, and the tray 2 is connected to the bracket 1 by bolts; the cover plate 4 is arranged on the top of the bracket 1, and a plurality of universal wheels 5 are bolted to the bottom of the bracket 1.

In actual applications, the predetermined range depends on the specifications of the battery box, but also on the space limitations of the installation environment of the movable stacked energy storage device, and is not limited to the above-mentioned predetermined range.
