Description

Technical Field

[0001] The present invention relates to the technical field of energy storage container battery racks, and in particular to a positionable and assembled energy storage container battery rack and an assembly method thereof. Background Art

[0002] Under the background of "dual carbon", new energy is developing rapidly. With the growth of electricity market demand and the upgrading of energy structure, the demand for electrochemical energy storage container equipment with integrated lithium iron phosphate batteries has maintained a rapid growth trend. In recent years, as an innovative energy storage solution, energy storage containers have many characteristics such as high energy density, long service life, high degree of integration, simple installation and lifting, green environmental protection and easy maintenance. They have broad application prospects and market potential in many fields such as energy supply, grid stability, microgrids, and emergency backup power supplies. Among them, marine energy storage containers, as the latest industry branch developed in the past two years, have broad application prospects. According to the characteristics of marine energy storage boxes, the battery rack structure is quite different from the battery rack of land energy storage boxes in structure.

[0003] Marine energy storage containers take into account the characteristics of ships moving on water, hull fluctuations, and large dynamic loads. A buffer structure must be designed for the connection between the battery rack and the box. The battery rack is designed as a whole frame structure, which can realize the overall independent structure of the battery rack. At the same time, buffer devices such as shock absorbers can be arranged between the box and the battery rack. In order to achieve its own structural strength, the whole frame battery rack mostly uses a combination of rectangular tubes and battery brackets. The current structural form of battery racks has a large deadweight, and it is difficult to position the rectangular tubes by welding. The large number of welding points leads to large welding deformation, which is not conducive to mass production, low yield rate, and high rework costs.

[0004] In view of the above problems, we propose a positionable and assembled energy storage container battery rack and an assembly method thereof. Summary of the invention

[0005] The object of the present invention is to provide a positionable and assembled energy storage container battery rack and an assembly method thereof, so as to solve the problems raised in the above-mentioned background technology.
