Description

Technical Field

[0001] This utility model belongs to the field of energy storage battery box technology, specifically relating to an improved energy storage battery box. Background Technology

[0002] Existing energy storage battery boxes typically employ modular and standardized integrated system designs. For example, lithium-ion battery storage containers integrate battery packs, battery management systems (BMS), energy storage boxes, and communication and monitoring units into one unit, offering advantages such as rapid on-site deployment and standardized production. These systems use containers as carriers and achieve integrated energy storage and management functions through structured encapsulation, making them widely applicable in industrial and commercial energy storage, new energy power plants, and microgrid scenarios.

[0003] However, existing technologies have significant drawbacks: maintaining and managing modules or battery units requires disassembling the entire enclosure or removing internal components, making the process complex and time-consuming. For example, while traditional energy storage battery cabinets offer flexible deployment capabilities, their enclosed structure necessitates disassembling the enclosure or battery stack structure during maintenance, which not only prolongs maintenance time but may also affect system stability. Especially for stacked battery units, replacing middle or bottom-level units requires disassembling layer by layer, further reducing maintenance efficiency and failing to meet the demands of rapid operation and maintenance. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0005] An improved energy storage battery box includes a box body and a cover. The box body houses a management module and stacked battery cells. The box body has a first cavity and a second cavity. The first cavity houses the management module, and the second cavity houses the battery cells. The first cavity has an openable first panel on its side. The second cavity has a mounting bracket for securing the battery cells, and its side also has an openable second panel. The openable first and second panels allow for direct inspection and maintenance of the management module and battery cells without removing them from the box, significantly reducing maintenance time compared to traditional battery boxes.

[0006] In a preferred embodiment of an improved energy storage battery box, the mounting frame includes fixing mechanisms on both sides and several mounting plates in the middle for mounting battery units. The mounting plates are connected and fixed to the fixing mechanisms. The spacing between the mounting plates is greater than the height of the battery unit to facilitate removal of the battery unit from the side. This design allows for lateral access to battery units, especially those located in the middle or bottom of a stacked arrangement, achieving rapid replacement and significantly reducing battery unit replacement time.

[0007] In a preferred embodiment of an improved energy storage battery box, the fixing mechanism includes two sets of synchronous lifting assemblies, each set consisting of several hinged connecting pipes. When the user lifts the top mounting plate, the synchronous lifting assemblies drive all mounting plates to rise equidistantly, further facilitating the replacement of battery cells.

[0008] In a preferred embodiment of an improved energy storage battery box, the mounting plate is provided with a support mechanism, which includes a foldable support column and a soft pad on top of the support column. The support mechanism can support the upper mounting plate and fix the posture of the mounting frame when it is fully opened.

[0009] In a preferred embodiment of an improved energy storage battery box, the support mechanism further includes a storage base. The bottom end of the support column is hinged to one end of the storage base, and the storage base has a storage groove for storing the support column. Connecting rods are hinged to both sides of the storage base, and the free ends of the two sets of connecting rods are connected by a positioning pin. The support column has a sliding groove for the positioning pin to slide in, and a fixing trigger is also provided on the support column. When the support column is fully extended, the fixing trigger limits the positioning pin. The fixing trigger automatically locks the positioning pin when fully extended to prevent the support column from accidentally folding due to the weight of the upper battery.

[0010] In a preferred embodiment of an improved energy storage battery box, the second plate has two sets, which are symmetrically arranged on the front and rear sides of the second cavity. The bottom of the second plate is hinged to the box body. This double-symmetrical second plate design enables multi-directional maintenance of the battery cells.

[0011] In a preferred embodiment of an improved energy storage battery box, the management module has an output connector for power output, which is fixed on the first plate to facilitate module wiring.

[0012] Compared with the prior art, this application has the following beneficial technical effects: the management module and battery unit can be inspected and maintained by opening the first and second plates without having to remove the management module and battery unit from the enclosure, which greatly reduces maintenance time.

The box body 100 has a first cavity 120 and a second cavity 130. The first cavity 120 houses the management module 122, and the second cavity 130 houses the battery cells 132. An openable first plate 121 is provided on the side of the first cavity 120. A mounting bracket 200 for fixing the battery cells 132 is provided in the second cavity 130, and an openable second plate 131 is provided on the side of the second cavity 130. The first plate 121 and the second plate 131 can be opened, allowing for direct inspection and maintenance of the management module 122 and battery cells 132 without removing them from the box body 100, significantly reducing maintenance time compared to traditional battery boxes.

[0027] In this application, references Figure 4 The mounting bracket 200 includes fixing mechanisms 210 on both sides and several mounting plates 220 located in the middle. The mounting plates 220 are used to support the battery units 132 and are connected to the fixing mechanisms 210.

This design is particularly beneficial for the rapid replacement of stacked middle or bottom layer units, greatly reducing the time required to replace the battery units 132. The fixing mechanism 210 includes two sets of synchronous lifting assemblies 211, each set of synchronous lifting assemblies 211 being composed of several connecting tubes 212 hinged together. When the user lifts the top mounting plate 220, the synchronous lifting assembly 211 drives all mounting plates 220 to rise at equal intervals, further facilitating the replacement of the battery units 132.

[0028] To ensure the stability of the mounting bracket 200 after it is opened, a support mechanism 300 is provided on the mounting plate 220. The structure of the support mechanism 300 is as follows: Figure 5 and Figure 6 As shown, the support mechanism 300 includes a storage base 310 and a support column 320. The bottom end of the support column 320 is hinged to one end of the storage base 310. The storage base 310 has a storage groove 311, and the support column 320 can be folded and stored in the storage groove 311. The top of the support column 320 has a soft pad 321, which can abut against the upper mounting plate 220 when unfolded. The storage base 310 has connecting rods 312 hinged to both sides. The free ends of the two sets of connecting rods 312 are connected by positioning pins 313. The support column 320 has a sliding groove 322 for the positioning pins 313 to slide. The support column 320 also has a fixing trigger 323, which is connected to the support column 320 through a torsion spring shaft. When fully unfolded, the fixing trigger 323 automatically locks the positioning pins 313 to prevent the support column 320 from accidentally folding due to the weight of the upper battery.

[0029] Furthermore, the second plate 131 consists of two sets symmetrically arranged on the front and rear sides of the second cavity 130, with its bottom hinged to the housing 100 to enable multi-directional maintenance of the battery unit 132. The management module 122 has an output connector 123 for power output, which is fixed to the first plate 121 to facilitate module wiring.
