TECHNICAL FIELD

The present disclosure belongs to the field of energy storage technology and relates to a battery cabinet and an energy storage container including the battery cabinet.

BACKGROUND

Battery box is a box body used to mount batteries, usually made of iron material. In energy storage system, battery cabinet is usually used to fixedly mount multiple battery boxes to provide powerful electricity. With the development and application of the energy storage system, the demand for cost reduction of energy storage equipment using battery cabinet is becoming increasingly apparent, one solution is to increase the number of batteries inside a single battery box in the battery cabinet and reduce the cost of the corresponding components by cost-sharing. However, with the increase of battery box power, the requirement for the fixed strength of the battery box fixed in the battery cabinet is also increasing, and it is also necessary to improve the mounting convenience of the battery box in the battery cabinet.

CN209786027U discloses a fixing structure of a battery box, which realizes the pressing and fitting in a height direction H by means of a bottom wall of a support unit and a position limiting member located within the support unit. However, there are certain defects, i.e., in order to ensure the mounting stability between the battery box and the support unit, and to ensure the stability of position limitation, it is necessary for the position limiting member to provide a strong compressing force on the battery box in the height direction, at this time, the mount of the battery box in an X direction requires a large force to slide in or slide out. Therefore, there may be a contradiction between the stability of position limitation and the convenience of pushing in and pushing out.

On the other hand, the energy storage container has a wide range of applications in the energy field, with the functions of coping with peak power demand, supporting microgrid operation, and providing emergency backup energy, etc. Moreover, due to its modularized design, the energy storage container has good portability and flexibility, and can be rapidly deployed and moved. The common energy storage container consists of a battery compartment, a power conversion compartment, a control and monitoring compartment and a fire compartment, wherein the battery compartment is the core of the whole system. Once the battery in the battery compartment fails, it must be repaired in the first time to avoid further damage. In practice, due to the properties and characteristics of the battery, it is prone to generate uncertainties, which in turn affects the efficiency of repair, resulting in additional time costs and waste of human resources. In order to reduce transportation costs and quickly respond to the malfunction and repair of the energy storage container, it will also choose to build a preparation warehouse nearby, but this will additionally bring a series of additional expenses such as construction costs and inventory management, etc. The present disclosure also proposes an energy storage container to solve these problems.

Based on the embodiments in the present disclosure, all other embodiments obtained by the person skilled in the art are within the scope of protection of the present disclosure.

Referring to FIG. 1, the present embodiment provides a battery cabinet including a battery rack, the battery rack comprises a mounting bracket 2 and a plurality of mounting zones located within the mounting bracket 2. The battery cabinet is used to provide multiple battery boxes 1. The FIG. 1 shows a positional state of the battery cabinet including the battery box 1 in actual use, wherein the spatial position is represented by an XYZ coordinate system, wherein the Z-axis represents a vertical direction and the XY plane is a horizontal plane. As shown in FIG. 1, the mounting bracket 2 may comprise a plurality of vertical brackets 201 extending along a vertical direction Z and a plurality of horizontal brackets 202 extending along a horizontal direction. The mounting zone may be divided according to actual needs. As shown in FIG. 1, two mounting zones Zone1, Zone2 are arranged side by side on the left and right, and cluster racks 3 are provided on both sides in each mounting zone, and the two cluster racks 3 are set opposite to each other for jointly setting one battery box 1.

As shown in FIG. 3, the cluster rack 3 comprises a side wall 35 and a bottom wall 31 extending along a mounting direction X, and the cluster rack 3 further comprises an opening end 32 for the battery box 1 to be mounted into. It is to be noted that, as shown in conjunction with FIG. 1 and FIG. 3, when mounting the battery box 1 to the battery rack, the direction indicated by the arrow along the X-axis is the mounting direction, i.e., the battery box 1 enters into the space between the two cluster racks 3 from the opening end 32 along the direction indicated by the X-axis and is slidably mounted to the two cluster racks 3 inwardly along the side walls 35 and the bottom walls 31.

As shown in FIG. 1 and FIG. 2, the battery box 1 is roughly a rectangular shape, which has a certain width along the direction Y. Therefore, the direction Y is referred to as the width direction, and the battery box 1 is provided with mounting guide parts 11 on both sides of the width direction Y. In other words, the two mounting guide parts 11 on both sides extend along the mounting direction X. Referring to FIG. 1 to FIG. 3, the two mounting guide parts 11 of the battery box 1 can be slidably mounted on the bottom walls 31 of the two cluster racks 3 along the mounting direction X. The cluster rack 3 is further provided with a first sloping surface 33, an acute angle is arranged between the first sloping surface 33 and the bottom wall 31, and the opening direction of the acute angle is directed towards the entry direction of the battery box 1, the mounting guide part 11 is provided with a first inclined surface 12 for touching and fitting against the first sloping surface 33. As shown in FIG. 2, the mounting guide part 11 may be a block structure or a frame structure made of bent sheet metal, which is fixed to both sides of the battery box 1 in the width direction Y by welding, bonding, or screw connection, etc., and is used for mounting guidance of the battery box 1 on the battery rack.

As shown in FIG. 2, an acute angle is also arranged between the first inclined surface 12 and the bottom surface of the mounting guide part 11, in some embodiments, the acute angle is the same as the angle of the acute angle that arranged between the first sloping surface 33 and the bottom wall 31. As shown in FIG. 2 and FIG. 3, the meaning of the first inclined surface 12 is touching and fitting to the first sloping surface 33 is that when the battery box 1 has completed its setting on the battery rack and the first inclined surface 12 is in full or partial touch with the first sloping surface 33. The width of the first inclined surface 12 may be greater than, equal to, or less than the width of the first sloping surface 33.

FIG. 6 shows a state when the battery box 1 has been provided on the battery rack. In order to fix the position of the battery box 1, a locking member is also provided between the battery box 1 and the battery rack for pressing the first inclined surface 12 tightly against the first sloping surface 33 along the mounting direction X.

If the position of the first sloping surface 33 on the cluster rack 3 is different, the first inclined surface 12 on the corresponding mounting guide part 11 should be adjusted accordingly. It is particularly noted that the mounting guide part 11 may be a structure of unibody or a structure in which a plurality of structural members are connected by welding or other connecting methods, without limitation herein.

As shown in FIG. 2, in some embodiments, the battery cabinet of the present disclosure further comprises the plug 5, the plug 5 is provided above the mounting guide part 11 for pressing and fitting against the mounting guide part 11 in the height direction Z. Accordingly, in conjunction with FIG. 3, in some embodiments, the cluster rack 3 is provided with the slot 6 for fitting with the plug 5.

As shown in FIG. 2, FIG. 3, and FIG. 7, the plug 5 may be a separate structural member, after the mounting guide part 11 has entered into the cluster rack 3, the plug 5 is then mounted, the upper part of the plug 5 touching against the top surface of the slot 6, so as to enable the lower part of the plug 5 to be realized downwardly pressing and fitting against the mounting guide part 11 in the height direction Z, which increases the mounting stability of the mounting guide part 11 with the cluster rack 3.

The cluster rack 3 can be a sheet metal part, the bottom wall 31 and the first sloping surface 33 can be bent by the sheet metal, and the top of the cluster rack 3 also comprises a bent top wall 34, and the opening height of the opening end 32 of the cluster rack 3 is larger, which is convenient for the alignment and push-in of the mounting guide part 11, in addition to being able to form the slot 6, which is convenient for use with the plug; in addition, the first sloping surface 33 can be a separate sheet metal part, which is fixed to the side wall 35 of the cluster rack 3 by welding or other methods.

Further, as shown in FIG. 3, the slot 6 is provided with a second sloping surface 61, an acute angle is also arranged between the second sloping surface 61 and the bottom wall 31, and the opening direction of the acute angle also towards the entry direction of the battery box 1.

It is further noted that the first direction D1, the second direction D2 and the height direction of the battery pack case are perpendicular to each other in the present disclosure.

The present disclosure adopts a thin plate structure for the surround plate structure of the box body, which reduces the weight of the box body, reduces the use of materials, and lowers the cost of the box body, and by designing multiple protrusions on the side surround plate of the box body, the strength of the side surround plate is increased to prevent deformation of the side surround plate.

Currently, multiple modules are arranged in the battery pack, the module fixing beam structure is designed in the battery pack, and the modules are fixed to the module beam structure of the battery pack case by bolts, and in order to make the connection between the module crossbeam and the case body reliable, a welding method is used to weld the module crossbeam in the battery pack case. However, in the related technology, after the module is welded, the weld seam between the module crossbeam and the case body will have excessive protrusion and large welding point. The thick weld seams are prone to interfere with the battery cell within the module, causing failure of the insulating layer of the battery cell. Even if the battery cell does not interfere with the weld seam during the assembly process, the battery cell will expand after the charging and discharging cycles, there is still a risk of interfering between the weld seam and the battery cell, which makes the module in the battery pack a safety hazard of short-circuit.

To address the risk of the weld seam interfering with the battery cell of the battery set in the prior art, as shown from FIG. 16 to FIG. 18, the present disclosure provides at least one module beam 303 in the battery box 1 for mounting the battery set 302, the module beam 303 is welded to the bottom plate 101 of the battery box 1, and a weld seam 304 is formed by welding the connection position between the module beam 303 and the bottom plate 101, the module beam 303 is connected to the battery set 302, and a connection position between the module beam 303 and the bottom plate 101 is provided with an accommodation section for accommodating the weld seam 304. It is to be noted that the bottom plate 101 of the battery box 1 in this embodiment is of the same structure as the bottom plate 101 of the battery box 1 of the previously described embodiment, but this is not to be used as a limitation that other components must be the same in different embodiments. The battery set 302 in this embodiment may be the same or different from the battery set 109 in the previously described embodiment.

Specifically, the accommodation section comprises at least one groove 3031 setting on the module beam 303, and the weld seam 304 located within the groove 3031.

It can be understood that the module beam 303 of the present disclosure is provided with the groove 3031, and the weld seam 304 is internalized in the groove 3031 for avoiding the problem of interference between the battery cell in the battery set 302 and the weld seam 304, and circumventing the safety problem of a short-circuiting fire of the battery set 302 in the battery pack. Further, the present disclosure adopts the groove 3031 as the accommodation section, which does not occupy the internal space of the battery box 1.

Preferably, as shown in FIG. 16 and FIG. 17, the accommodation section comprises at least one groove 3031 setting on the side of the module beam 303, the groove 3031 is set along a length direction of the module beam 303 so as to enable the module beam 303 to form a sheltering part 3033 for sheltering the weld seam 304.

It is noted that the depth of the inward depression of the groove 3031 is greater than or equal to the width of the weld seam 304 to allow the weld seam 304 to be concealed in the groove 3031.

Specifically, the groove 3031 comprises a first inner wall surface 30311 and a second inner wall surface 30312, one side of the second inner wall surface 30312 is connected to the bottom plate 101 of the battery box 1 and another side is connected to the first inner wall surface 30311. After the first inner wall surface 30311 and the second inner wall surface 30312 are connected, the angle between the first inner wall surface 30311 and the second inner wall surface 30312 is a non-acute angle.

In an optional embodiment of the present disclosure, as shown in FIG. 19, the first inner wall surface 30311 is arranged parallel to the bottom plate 101, the second inner wall surface 30312 is arranged perpendicular to the bottom plate 101, and the angle between the first inner wall surface 30311 and the second inner wall surface 30312 is 90 degrees.

It should be noted that in the embodiment where the first inner wall surface 30311 is provided in parallel with the bottom plate 101, since the weld seam 304 is located at the bottom plate 101 (i.e., the welding point is also located at the bottom plate 101), the sheltering part 3033 can interfere with the welding device and cause difficulties for the assemblers in their welding work.

Preferably, in order to solve the above problem, as shown in FIG. 16, in this embodiment, the first inner wall surface 30311 is not arranged in parallel with the bottom plate 101, the second inner wall surface 30312 is perpendicular to the bottom plate 101, and the angle between the first inner wall surface 30311 and the second inner wall surface 30312 is an obtuse angle. In this way, the first inner wall surface 30311 extends obliquely upwards relative to the bottom plate 101, and the cross-sectional area of the opening of the groove 3031 is larger than the cross-sectional area of the second inner wall surface 30312, which provides the channel for the welding device to reach through and reduces the difficulty of the production process.

In another embodiment provided in the present disclosure, as shown in FIG. 20, the first inner wall surface 30311 is arranged parallel to the bottom plate 101, the second inner wall surface 30312 is arranged perpendicular to the bottom plate 101, and the angle between the first inner wall surface 30311 and the second inner wall surface 30312 is 90 degrees. Meanwhile, the opening edge 3031a of the groove 3031 is in a circular arc shape.

It should be noted that the embodiment shown in FIG. 20 is an improvement of the embodiment shown in FIG. 19. The opening edge 3031a of the groove 3031 has a circular arc shape, which facilitates welding and to some extent avoids bumping with other components at the opening edge 3031a.

In another embodiment provided by the present disclosure, as shown in FIG. 21, the groove 3031 comprises an inner plane 30313, one side of the inner plane 30313 is connected to the bottom plate 101 and another side serves as an opening edge of the groove 3031, and the angle between the inner plane 30313 and the bottom plate 101 is an acute angle. It is to be understood that in this embodiment, the groove 3031 is an inner plane 30313 inclined with respect to the bottom plate 101. The angle between the inner plane 30313 and the bottom plate 101 is an acute angle, and the groove 3031 is a concave structure with a large opening and a small bottom, so as to facilitate the welding device to extend into the groove 3031 to perform welding operations.

In another embodiment provided by the present disclosure, as shown in FIG. 22, the inner wall surface 3031b of the groove 3031 is a curved surface.

In addition, the present disclosure also provides an embodiment, as shown in FIG. 23, the inner wall surface 3031c of the groove 3031 is in a stepped shape.

Preferably, the accommodation section comprises at least two grooves 3031, the two grooves 3031 are spaced apart along the length direction of the module beam 303.

It is noted that after the welding is completed and the weld seam 304 is formed, the surface of the weld seam 304 is uneven and has sharp edge, sharp corner, and burr. Since the sheltering part 3033 is provided above the weld seam 304, the surface of the expanded battery cell is blocked by the sheltering part 3033 above the weld seam 304, which avoids potential interference (where the surface of the expanded battery cell enters directly into the notch of the hidden groove 3031) between the battery cell in the module and the weld seam 304 or direct interference between the battery set 302 and the sharp edge, sharp corner, and burr of the weld seam 304 during the assembly and mounting of the battery box.

Further, the battery box 1 comprises at least two module beams 303, the two module beams 303 are spaced apart in the cavity of the battery box 1. And the two module beams 303 are symmetrically arranged in the cavity of the battery box 1, each module beam 303 is affixed to the battery box 1. The top surface of the module beams 303 is provided with bolt holes for fixing the battery set 302, and multiple battery sets 302 are mounted on the two module beams 303.

In an optional embodiment, the battery box 1 comprises at least three module beams 303, the three module beams 303 are spaced apart in the battery box 1.

In summary, the present disclosure provides the accommodation section on the battery pack case to isolate the weld seam from the battery set, so as to avoid the battery set from interfering with the weld seam during assembly and mounting, or, the battery cell of the battery set expanding and touching with the weld seam after charging and discharging cycles, which will cause the short circuit of the module inside the battery box. Further, the accommodation section of the present disclosure is provided as a groove, so as to solve the safety hazard of short circuit of the module in the battery box without occupying the internal space of the battery box.
