However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Referring to fig. 1-6, in some embodiments, an integrated cabinet includes: a front panel 100 and a rear panel 110 arranged at intervals in the front-rear direction, and two side panels 120 arranged at intervals in the left-right direction; the front panel 100, the rear panel 110 and the side panels 120 together define a first receiving area 130 and a second receiving area 140 arranged up and down, and a distance in the front-rear direction of one side surface of the front panel 100 and the rear panel 110 opposite to each other is smaller than a distance in the left-right direction of one side surface of the two side panels 120 opposite to each other; at least one side panel 120 is provided with a maintenance opening 150, and a first cover plate 160 is provided on the maintenance opening 150.

The thickness of the integrated cabinet in the front-back direction is reduced by limiting the distance between the front panel 100 and the rear panel 110, so that the space occupied by the energy storage device in the front-back direction is reduced, and the maintenance opening 150 is arranged on the side panel 120, so that the battery assembly is mounted and electrically connected through the maintenance opening 150, and the thickness of the integrated cabinet in the front-back direction is further reduced.

It can be understood that the first receiving area 130 and the second receiving area 140 are partitions of a space defined by the front panel 100, the rear panel 110, and the two side panels 120 spaced left and right, and the first receiving area 130 is communicated with the second receiving area 140.

In some embodiments, the distance between the surfaces of the front panel 100 and the rear panel 110 opposite to each other along the front-back direction is 100-400 mm.

The distance between the side surfaces of the front panel 100 and the rear panel 110 opposite to each other in the front-rear direction, i.e., the thickness of the integrated cabinet in the front-rear direction, it can be understood that the thickness of the integrated cabinet in the front-rear direction can be selected according to the thickness of an object to be accommodated. Taking the case that the first accommodation area 130 needs to carry the inverter and the second accommodation area 140 needs to carry the battery assembly as an example, the inverter and the integrated cabinet are placed in the same direction, that is, the side surface of the inverter is opposite to the side panel 120 of the integrated cabinet, the battery assembly and the integrated cabinet are placed in the same direction, that is, the side surface of the battery assembly is opposite to the side panel 120 of the integrated cabinet, and the thickness of the integrated cabinet in the front-back direction is determined based on the larger thickness of the inverter and the battery assembly in the front-back direction. In the embodiment, the thickness of the inverter in the front-back direction is large, so that the thickness of the inverter in the front-back direction is taken as a reference, for example, the thickness of the inverter in the front-back direction is 80-380 mm, and a certain gap is required between the front panel 100 and the rear panel 110 for mounting the inverter, so that the distance between the front panel 100 and the rear panel 110 is 100-400 mm to meet the mounting requirement of the inverter.

In some embodiments, the distance between the front panel 100 and the rear panel 110 along the front-rear direction may be 160-260 mm. Specifically, the thickness of the integrated cabinet in the front-rear direction is determined based on the thickness of the inverter in the front-rear direction, for example, the thickness of the inverter in the front-rear direction is 150 to 250mm, the distance between the front panel 100 and the rear panel 110 for mounting the inverter is 160 to 260mm, and the inverter is tightly mounted between the front panel 100 and the rear panel 110 so as to reduce the distance between the front panel 100 and the rear panel 110 on the side surface opposite to each other in the front-rear direction.

It should be noted that, the thickness of the inverter and the battery assembly in the front-back direction is subject to practical use, in some embodiments, the thickness of the inverter in the front-back direction may be greater than the thickness of the battery assembly, in other embodiments, the thickness of the inverter in the front-back direction may be less than the thickness of the battery assembly, and even in some embodiments, the thickness of the inverter and the battery assembly in the front-back direction may be the same.

The thickness of the integrated cabinet in the front-back direction is reduced by limiting the distance between the front panel 100 and the rear panel 110, so that the space occupied by the energy storage device in the front-back direction is reduced.

In some embodiments, the distance between the two side panels 120 facing away from each other along the left-right direction is 300-800 mm.

The distance between the two side surfaces of the side panel 120 opposite to each other along the left-right direction, i.e., the width of the integrated cabinet in the left-right direction, it can be understood that the width of the integrated cabinet in the left-right direction can be selected according to the width of the object to be accommodated. Taking the first accommodation area 130 to support the inverter and the second accommodation area 140 to support the battery assembly as an example, the side surfaces of the inverter and the battery assembly are respectively opposite to the side panels 120 of the integrated cabinet, the widths of the inverter and the battery assembly in the left-right direction are obtained, and the width of the integrated cabinet in the left-right direction is determined based on the wider one of the inverter and the battery assembly. The width of the inverter of the present embodiment is relatively large, so the width of the inverter is taken as a reference, for example, the width of the inverter in the left-right direction is 280-780 mm, the distance between the two side panels 120 may be 300-800 mm, and a certain gap exists between the two side panels 120 and the inverter, so as to meet the installation requirement of the inverter.

In some embodiments, the distance between the surfaces of the two side panels 120 facing away from each other along the left-right direction is 400-650 mm.

Specifically, the width of the integrated cabinet in the left-right direction is determined based on the width of the inverter in the left-right direction, for example, the width of the inverter in the left-right direction is 390-640 mm, the distance between the two side panels 120 may be 400-650 mm, and at this time, the gap between the inverter and the two side panels 120 is small, and the distance between the two side panels 120 in the left-right direction is reduced by tightly mounting the inverter and the side panels 120.

It should be noted that the width of the inverter and the battery assembly in the left-right direction is subject to practical use, in some embodiments, the width of the inverter in the left-right direction may be greater than the width of the battery assembly in the left-right direction, in other embodiments, the width of the inverter in the left-right direction may be smaller than the width of the battery assembly in the left-right direction, and even in some embodiments, the width of the inverter in the left-right direction may be the same as the width of the battery assembly in the left-right direction.

The width of the integrated cabinet in the left-right direction is reduced by limiting the distance between the two side panels 120, and the space occupied by the energy storage device in the left-right direction is reduced.

In some embodiments, a ratio of a distance between one side surface of the front panel 100 and one side surface of the rear panel 110, which are opposite to each other, in the front-back direction to a distance between one side surface of the two side panels 120, which are opposite to each other, in the left-right direction is less than or equal to 65%, for example, a ratio of a distance between one side surface of the front panel 100 and one side surface of the rear panel 110, which are opposite to each other, in the front-back direction to a distance between one side surface of the two side panels 120 in the left-right direction is 20% to 50%.

In some embodiments, the thickness of the front panel 100, the rear panel 110 and the side panel 120 is 0.5mm to 5mm, for example 2mm, it is understood that the thinner the thickness of the front panel 100, the rear panel 110 and the side panel 120 is, the smaller the installation space occupied by the corresponding integrated cabinet in the front-rear direction and the left-right direction is, however, the thinner the thickness is, the poorer the stress resistance of the corresponding front panel 100, the rear panel 110 and the side panel 120 is, the thicker the thickness of the front panel 100, the rear panel 110 and the side panel 120 is, the stronger the stress resistance of the front panel 100, the rear panel 110 and the side panel 120 is, and therefore, the thickness of the front panel 100, the rear panel 110 and the side panel 120 is selected according to actual requirements.

In some embodiments, the surface of the rear panel 110 facing the first receiving area 130 is provided with hanging plates 170, and the hanging plates 170 are distributed with hanging holes 180 along the left-right direction.

It will be appreciated that the hanging hole 180 is used for mounting the inverter, and correspondingly, a hook is provided on a surface of the inverter facing the rear panel 110, and the inverter is fixed by the hook being engaged with the hanging hole 180. The gap between the inverter and the rear panel 110 can be reduced by means of the hanging holes 180 and the hanging hooks, so that the thickness of the integrated cabinet in the front-back direction is reduced. Of course, in other embodiments, the inverter may be fixed in other manners.

The integral type rack still includes: top panel 190, top panel 190 are located the top portion of front panel 100, back panel 110 and side board 120, and top panel 190 can be detachable with front panel 100, back panel 110 and side board 120 and be connected, can be through taking apart top panel 190 when the installation inverter to from the top of integral type rack from last installation under in the direction of perpendicular to top panel 190, thereby make the couple of inverter and hanging hole 180 change the cooperation installation.

In some embodiments, the guide structure 200 is disposed in the first receiving area 130, and the guide structure 200 is disposed on the surface of the rear panel 110 facing the first receiving area 130 in a left-right symmetry manner.

It can be understood that, when the inverter is installed from the front-rear direction, the guide structure 200 limits the inverter so that the inverter is installed in the direction guided by the guide structure 200, so that the inverter is not displaced during the installation process.

The guide structure 200 is a triangular guide plate, and two sides of the guide structure 200 are connected to the rear panel 110 and the side panel 120, respectively.

The triangular guide plate has two sides and the third side, which is directed from the side panel 120 to the rear panel 110, for guiding. There is no sharp corner on the third side of the guide structure 200 facing the inverter, so that the inverter is prevented from colliding with the guide structure 200 strongly during installation, and the probability of damage to the inverter during installation is reduced.

In some embodiments, the integrated cabinet further comprises: the third accommodating section 210, and the second accommodating section 140 communicates with the first accommodating section 130 through the third accommodating section 210.

The third receiving region 210 may be used to mount a switch for controlling the operation of the energy storage device, through which the inverter is electrically connected with the battery assembly.

It should be noted that the first accommodating section 130, the second accommodating section 140, and the third accommodating section 210 are partitions that collectively define an area for the front panel 100, the rear panel 110, and the side panels 120, and the first accommodating section 130, the second accommodating section 140, and the third accommodating section 210 are communicated with each other.

In some embodiments, the side panel 120 is provided with a first groove 220, the first groove 220 extends toward the third accommodating area 210, and a plurality of through holes 230 are formed on a side of the first groove 220 facing the third accommodating area 210.

The energy storage device passes through the through hole 230 on the first groove 220 to lead out the alternating current generated by the operation of the inverter.

In some embodiments, the first groove 220 is recessed toward the third accommodation region 210, a groove bottom surface formed at a groove bottom of the first groove 220 is an inclined surface, a depth of the first groove 220 toward the third accommodation region 210 is gradually increased in a top-to-bottom direction, when an alternating current is led out in an output line manner, the output line passes through the through hole 230, and a direction in which the output line passes through the through hole 230 is perpendicular to the inclined surface, so that a water drop may be prevented from being hung on the output line.

The distance of one side surface that this application embodiment back to each other through control front panel 100 and rear panel 110 along the fore-and-aft direction reduces the shared space of integral type rack in the fore-and-aft direction, and through set up maintenance opening 150 on side panel 120 to accessible maintenance opening 150 carries out depositing and the electricity of battery pack, thereby further reduces the thickness of integral type rack in the fore-and-aft direction.

An embodiment of the present application further provides an energy storage device, including: the above-mentioned integrated cabinet, inverter, battery pack and switch will be described below with reference to the accompanying drawings.

Referring to fig. 1 to 12, an energy storage device includes: the integrated cabinet (refer to fig. 1 to 6); an inverter 240, the inverter 240 being located in the first accommodation area 130, and a value of a first thickness of the inverter 240 in the front-rear direction being smaller than a value of a first width of the inverter 240 in the left-right direction; and a battery assembly 250, the battery assembly 250 being located in the second receiving region 140, the battery assembly 250 being electrically connected to the inverter 240.

By limiting the installation direction of the inverter 240, the space required by the inverter 240 in the front-rear direction is reduced, and the thickness of the integrated cabinet in the front-rear direction is reduced.

In some embodiments, a surface of the inverter 240 facing the rear panel 110 is provided with a hook 260, and the hook 260 is engaged with a hanging hole 180 provided on a surface of the hanging plate 170 facing the first receiving area 130 to fix the inverter 240 to the hanging hole 180 by the hook 260.

Through the cooperation between couple 260 and hanging hole 180 in order to realize closely laminating between inverter 240 and rear panel 110 to reduce the connecting gap between inverter 240 and the rear panel 110, and then reduce the required space that occupies of energy memory in the front and back direction, and can reduce the required space that occupies of connecting inverter 240 and rear panel 110 fixed connection through the setting of hanging hole 180.

The integrated cabinet further comprises a top panel 190, the top panel 190 is located at the top end portions of the front panel 100, the rear panel 110 and the side panel 120 and connected with the front panel 100, the rear panel 110 and the side panel 120, the top panel 190 is provided with an air outlet 300, the side panel 120 is provided with an air inlet 310, the back of the inverter 240 is provided with a heat dissipation component 320, the air outlet 300 is opposite to the top surface of the heat dissipation component 320, the area of the air outlet 300 is larger than or equal to the orthographic projection area of the heat dissipation component 320 on the top panel 190, and the air inlet 310 is opposite to the side wall of the heat dissipation component 320.

When the inverter 240 operates, heat generated by the inverter 240 is transferred to the air around the inverter 240, so that the temperature of the air in the first accommodation area 130 is increased, the air is heated and expanded, the density is reduced, the volume is increased, but the mass is not changed, the buoyancy by the surrounding air is increased, thereby causing the heated air in the first receiving area 130 to rise and leave the first receiving area 130 through the outlet 300, the air in the first receiving area 130 to flow upward and outward, the atmospheric pressure to press the air outside the first receiving area 130 into the first receiving area 130 through the inlet 310, thereby realizing air circulation, transferring heat generated by the operation of the inverter 240 to the outside through the air outlet 300 and the air inlet 310 to achieve the effect of reducing the temperature in the first receiving region 130, and the arrangement of a cooling fan can be reduced, so that the complexity, the cost and the system energy consumption of the photovoltaic device are reduced.

In some embodiments, there is a first gap between the battery assembly 250 and the rear panel 110, and the distance in the front-rear direction of the first gap is 30mm or less.

It is understood that when the battery assembly 250 is assembled with the rear panel 110, there is inevitably a gap between the battery assembly 250 and the rear panel 110, and the depth of the second receiving region 140 in the front-rear direction, which is occupied by mounting the battery assembly 250, can be reduced by reducing the gap between the battery assembly 250 and the rear panel 110, thereby reducing the amount of space that the energy storage device needs to occupy in the front-rear direction.

In some embodiments, there is a second gap between the inverter 240 and the rear panel 110, and the distance of the second gap in the front-rear direction is 30mm or less.

It is understood that when the inverter 240 and the rear panel 110 are assembled together, a second gap is inevitably formed between the inverter 240 and the rear panel 110, and the depth of the first accommodation region 130 in the front-rear direction, which is occupied by the inverter 240 when mounted, can be reduced by reducing the second gap between the inverter 240 and the rear panel 110, thereby reducing the amount of space that the energy storage device needs to occupy in the front-rear direction.

In some embodiments, the battery assembly 250 includes at least two battery modules 270, the battery modules 270 are stacked one on another in the second receiving region 140, at least one battery module 270 is provided per layer, and a second thickness of the battery module 270 in the front-rear direction has a value smaller than a second width of the battery module 270 in the left-right direction.

The battery module 270 is installed in a manner of being stacked up and down, so that the space occupied by the battery assembly 250 in the front-rear direction can be reduced, and the installation direction of the battery module 270 is limited, so that the installation direction of the battery module 270 is installed in the left-right direction, and the space occupied by the battery assembly 250 in the front-rear direction is reduced.

The socket 280 of the battery assembly 250 is disposed toward the maintenance opening 150, and the connection line 410 leading from the socket 280 is disposed in a region between the battery assembly 250 and the maintenance opening 150 at a portion of the second receiving area 140.

Taking the example that the battery assembly 250 includes two battery modules 270, the two battery modules 270 are electrically connected in parallel, the parallel connection of the battery modules 270 is realized through the socket 280, and the battery modules 270 are electrically connected with the inverter 240 through the socket 280, and the socket 280 is disposed in the region between the battery assembly 250 and the maintenance opening 150, so that the space occupied by the socket 280 and the connection line 410 in the front-rear direction can be reduced, and the space occupied by the energy storage device in the front-rear direction can be reduced.

In some embodiments, a first horizontal channel 330 and a first vertical channel 340 are also provided around the service opening 150, and the first horizontal channel 330 is connected to the first vertical channel 340.
