[0054] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0055] Since the energy people need is highly temporal and spatial, in order to rationally utilize energy and improve energy utilization, it is necessary to use a medium or device to store one form of energy in the same way or convert it into another form of energy, and then release it in a specific form of energy based on future application needs.

[0056] At present, green energy mainly includes solar energy, wind energy, etc. However, solar energy and wind energy generally have problems of strong intermittency and large volatility, which will cause unstable voltage of the green power grid (not enough electricity during peak hours and too much electricity during low hours). Unstable voltage will cause damage to electricity. Therefore, it may cause the problem of "wind and solar power abandonment" due to insufficient electricity demand or insufficient grid acceptance capacity.

[0057] To solve the problem of insufficient electricity demand or insufficient grid acceptance capacity, it is necessary to rely on the energy storage device 100. That is, the energy storage device 100 converts electrical energy into other forms of energy through physical or chemical means and stores it, and then converts the energy stored in the energy storage device 100 into electrical energy when needed. In simple terms, the energy storage device 100 is similar to a large "power bank", which stores electrical energy when there is sufficient light energy and wind energy, and releases the stored electrical energy when needed.

[0058] At present, energy storage (i.e., energy storage) has a wide range of application scenarios, including power generation side energy storage, grid side energy storage, renewable energy grid-connected energy storage, and user side energy storage. The corresponding types of energy storage devices 100 include:

[0059] (1) Large energy storage containers used in grid-side energy storage scenarios can serve as high-quality active and reactive power regulation power sources in the grid, achieve load matching of electric energy in time and space, enhance the ability to absorb renewable energy, and are of great significance in grid system backup, relieving peak load power supply pressure, and peak and frequency regulation;

[0060] (2) Small and medium-sized energy storage cabinets used in industrial and commercial energy storage scenarios (banks, shopping malls, etc.) on the user side, and small household energy storage boxes used in home energy storage scenarios on the user side, mainly operate in the mode of "peak shaving and valley filling". Since there is a large price difference in electricity charges at peak and valley locations according to electricity demand, after users have energy storage equipment, in order to reduce costs, they usually charge the energy storage cabinets / boxes during the low electricity price period; during the peak electricity price period, the electricity in the energy storage equipment is discharged for use, so as to save electricity bills. In addition, in remote areas, as well as areas prone to natural disasters such as earthquakes and hurricanes, the presence of the household energy storage device 100 is equivalent to the user providing a backup power supply for himself and the power grid, eliminating the inconvenience caused by frequent power outages due to disasters or other reasons.

[0061] Take the household energy storage scenario in user-side energy storage as an example to illustrate. Figure 1 A household energy storage system is shown, which includes an energy storage device 100 and an electric energy conversion device 200 (such as a photovoltaic panel), and a user load 300 (such as a street lamp, a household appliance, etc.). Specifically, the electric energy conversion device 200 can convert solar energy into electric energy during the period of low electricity prices, and store it through the energy storage device 100, and then supply the user load 300 for use during the peak electricity price, or supply the user load 300 for use when the power grid is out of power / power outage.

[0062] In combination with the above-mentioned situation of storing energy by physical or electrochemical means, taking electrochemical energy storage as an example, the energy storage device 100 includes at least one chemical battery, using the chemical elements in the chemical battery as the energy storage medium, so as to realize the charging and discharging process through the chemical reaction or change of the energy storage medium. In simple terms, the electric energy generated by light energy and wind energy is stored in at least one group of chemical batteries through the chemical reaction or change of the energy storage medium, and when the use of external electric energy reaches a peak, the electric energy stored in at least one group of chemical batteries is released for use through the chemical reaction or change of the energy storage medium, or transferred to a place where the electric energy is scarce for use.

[0063] The embodiment of the present application provides an energy storage device 100, which may be an energy storage box, an energy storage cabinet, etc., which is composed of energy storage units 20. Next, the energy storage device 100 is explained in detail by taking the energy storage cabinet as an example.

[0064] Figure 2 The schematic diagram of the structure of an energy storage cabinet provided by the embodiment of the present application is illustrated. Figure 3 The internal structure diagram of an energy storage cabinet provided by the embodiment of the present application is illustrated. Figure 2 and Figure 3 As shown, the energy storage cabinet includes: an energy storage cabinet 10 and an energy storage unit 20 , and the energy storage unit 20 is fixed in the energy storage cabinet 10 .

[0065] Among them, the energy storage unit 20 can be a battery pack, energy storage box, etc. composed of single cells. The single cells can be lithium-ion batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, magnesium-ion batteries, etc., and the single cells can be cylindrical, flat, rectangular, etc., and the implementation mode of the present application does not limit this.

[0066] Among them, Figure 4 or Figure 5 As shown, the energy storage unit 20 includes a base 21 (including at least a liquid cooling plate) and an energy storage package 22 located on the base 21, and the edge of the base 21 extends out of the energy storage package 22. In this way, the energy storage unit 20 can be fixedly assembled in the energy storage cabinet 10 by the portion of the base 21 extending out of the energy storage package 22, so as to avoid damage to the energy storage package 22 when assembling the energy storage unit 20.

[0067] like Figure 2 and Figure 3 As shown, the energy storage cabinet 10 includes a cabinet body 11 and a cabinet door 12 . A partition 111 is provided in the cabinet body 11 , and a battery compartment 112 is separated in the cabinet body 11 . The energy storage unit 20 is fixed in the battery compartment 112 .

[0068] Among them, Figure 3 As shown, a plurality of mounting racks 13 distributed along the height direction H of the cabinet 11 are provided in the battery compartment 112, so that a plurality of energy storage units 20 can be installed in the battery compartment 112 through the plurality of mounting racks 13, so as to improve the energy storage capacity of the energy storage cabinet. In combination with the above, the fixing of the energy storage unit 20 on the mounting rack 13 is the fixing of the portion of the base 21 extending out of the energy storage pack 22 on the mounting rack 13.

[0069] Optionally, a plurality of hanging ears are provided on the top of the cabinet 11, so as to facilitate the lifting and transportation of the energy storage cabinet 10 by connecting the hanging ears with the hanging rope. In addition, a warning device such as an indicator light can be provided on the cabinet door 12 to indicate the working state (such as charging state and discharging state) of the energy storage unit 20 in the battery compartment 112 of the cabinet 11 through the indicator light.

[0070] In some embodiments, Figure 3 As shown, a plurality of partitions 111 are provided in the cabinet 11 to separate a battery compartment 112 , a liquid cooling compartment 113 , a converter compartment 114 and an electrical compartment 115 in the cabinet 11 .

[0071] like Figure 3 As shown, the energy storage cabinet 10 also includes a liquid cooling unit 14 located in the liquid cooling compartment 113 and a liquid cooling unit 14 located in the battery compartment 112 , an energy storage inverter 15 located in the inverter compartment 114 , and a circuit breaker 17 , a high-voltage junction box 18 and a low-voltage junction box 19 located in the electrical compartment 115 .

[0072] Among them, the water inlet and outlet of the liquid cooling pipe 16 extend to the liquid cooling bin 113, and are respectively connected to the water inlet joint and the water outlet joint of the liquid cooling unit 14, so that when the energy storage unit 20 in the battery bin 112 is charged and discharged, the liquid cooling unit 14 cools down and dissipates the heat in the battery bin 112, thereby ensuring that the energy storage unit 20 is charged and discharged at a suitable ambient temperature.

[0073] The energy storage converter 15 is electrically connected to the energy storage unit 20 in the battery compartment 112 through the high-voltage junction box 18, and is used to be electrically connected to the external power grid through the circuit breaker 17, so as to realize the charging of the energy storage unit 20 by the external power grid through the AC-DC conversion of the energy storage converter 15, or to realize the power supply of the energy storage unit 20 to the power load through the DC-AC conversion of the energy storage converter 15. In addition, the energy storage converter 15 is also electrically connected to the liquid cooling unit 14 through the high-voltage junction box 18 and the low-voltage junction box 19, so as to realize the power supply of the liquid cooling unit 14 by the external power grid through the AC-DC conversion, or to realize the power supply of the liquid cooling unit 14 by the energy storage unit 20.

[0074] Figure 6 The schematic diagram of the structure of an energy storage cabinet 10 provided in the embodiment of the present application is illustrated. Figure 7 The schematic diagram of the structure of a mounting frame 13 provided in the embodiment of the present application is illustrated. Figure 8 Example Figure 7 The structural schematic diagram of the upper limit portion 133 of the mounting frame 13 is shown.

[0075] like Figure 6 , Figure 7 and Figure 8 As shown, the energy storage cabinet 10 includes: a mounting frame 13, including a first guide rail 131 and a second guide rail 132, the first guide rail 131 and the second guide rail 132 are respectively fixed on the first warehouse wall 1121 and the second warehouse wall 1122, the first guide rail 131 and the second guide rail 132 both include a support plate 1311, and a fixing portion 134 located at the front end 1314 of the support plate and a limiting portion 133 located at the rear end 1315 of the support plate; the limiting portion 133 includes a first vertical plate 1331 and a first inclined plate 1332, the first vertical plate 1331 is vertically arranged on the supporting surface 1312 of the support plate 1311, and the first vertical plate 133 The first side surface of the first guide rail 131 faces the front end 1314 of the support plate, the first inclined plate 1332 is connected to the side of the first vertical plate 1331 away from the support surface 1312, the first inclined plate 1332 is inclined in a direction close to the front end 1314 of the support plate away from the side of the first vertical plate 1331, and the side of the first inclined plate 1332 facing away from the corresponding warehouse wall includes a guide section 1333, and the distance between the guide section 1333 on the first guide rail 131 and the guide section 1333 on the second guide rail 132 decreases from the front end 1314 of the support plate to the rear end 1315 of the support plate, and the fixing portion 134 is used to be fixedly connected to the energy storage unit 20.

[0076] Among them, in combination with the above-mentioned situation that the energy storage cabinet 10 includes a cabinet body 11 and a cabinet door 12, the extension direction of the first guide rail 131 and the second guide rail 132 are both toward the cabinet door 12, so that when the cabinet door 12 is in an open state, the energy storage unit 20 is assembled along the first guide rail 131 and the second guide rail 132; in addition, the front end 1314 of the support plate is the end close to the cabinet door 12, and the rear end 1315 of the support plate is the end away from the cabinet door 12.

[0077] In the embodiment of the present application, the supporting surface 1312 on the first guide rail 131 and the second guide rail 132 is used to support the energy storage unit 20, and when assembling the energy storage unit 20, since the distance between the guide sections 1333 on the first guide rail 131 and the second guide rail 132 decreases in the direction from the front end 1314 of the support plate to the rear end 1315 of the support plate, the rear end of the energy storage unit 20 can be limited in the width direction W and depth direction S of the cabinet 11 based on the size of the energy storage unit 20 in the width direction W of the cabinet 11 through the guide sections 1333 on the first guide rail 131 and the second guide rail 132 or the first vertical plate 1331 to ensure the stability of the limiting of the energy storage unit 20; thereafter, the fixing portion 134 on the first guide rail 131 and the second guide rail 132 can be fixedly connected to the front end of the energy storage unit 20 to achieve the installation and fixation of the energy storage unit 20, so as to improve the stability of the assembly of the energy storage unit 20 in the energy storage cabinet 10.

[0078] In addition, based on the thickness (i.e., the dimension along the height direction H of the cabinet 11) and the length (i.e., the dimension along the width direction W of the cabinet 11) of the base 21 included in the energy storage unit 20, the abutment limitation of the rear end of the energy storage unit 20 can be selectively achieved through the guide section 1333 on the first vertical plate 1331 or the first inclined plate 1332, thereby achieving fixed assembly of energy storage units 20 of different models on the mounting frame 13, thereby improving the applicability of the energy storage cabinet 10.

[0079] During the specific assembly process of the energy storage unit 20 , the two sides of the rear end of the energy storage unit 20 are first supported on the support surfaces 1312 of the first guide rail 131 and the second guide rail 132 , respectively, and then the energy storage unit 20 is slid into the battery compartment 112 along the first guide rail 131 and the second guide rail 132 . At this time, if the base 21 of the energy storage unit 20 is thicker, the tail end of the energy storage unit 20 can abut against the guide section 1333 on the first inclined plate 1332. At this time, the guide section 1333 is combined to limit the energy storage unit 20 with different lengths of the base 21 in the width direction W of the cabinet 11; if the base 21 of the energy storage unit 20 is thinner, the tail end of the energy storage unit 20 can abut against the first vertical plate 1331. At this time, the energy storage unit 20 with different lengths of the base 21 is limited in combination with the size of the first vertical plate 1331 in the width direction W of the cabinet 11; thereafter, the energy storage unit 20 is fixed by the fixing portion 134 at the front end 1314 of the support plate, thereby realizing the installation and fixation of the energy storage unit 20 on the mounting frame 13, so as to improve the applicability of the energy storage cabinet 10 while ensuring the assembly stability of the energy storage unit 20.

[0080] The first vertical plate 1331 included in the limiting portion 133 may be a structural member integrated with the support plate 1311, or a structural member separately fixed on the support surface 1312 of the support plate 1311. In addition, the first vertical plate 1331 and the first inclined plate 1332 may be an integrated structure, or a structure in which adjacent sides are fixedly connected.

[0081] Optionally, for the first vertical plate 1331 included in the limiting portion 133, the height of the first vertical plate 1331 is greater than or equal to 18 mm, that is, the distance between the side of the first vertical plate 1331 away from the supporting surface 1312 and the supporting surface 1312 is greater than or equal to 18 mm. Figure 5 The energy storage unit 20 shown in the figure has a base 21 with a length, a width and a thickness of 808 mm, 1172 mm and 17 mm, respectively. Since the thickness of the base 21 is less than the height of the first vertical plate 1331, when the energy storage unit 20 is assembled in the installation, the end surface of the base 21 at the rear end of the energy storage unit 20 can be abutted against the first vertical plate 1331, and the first inclined plate 1332 limits the upper surface of the base 21 of the energy storage unit 20 in the height direction H of the cabinet 11; Figure 4 The energy storage unit 20 shown in the figure has a base 21 with a length, a width and a thickness of 820 mm, 1154 mm and 36 mm, respectively. Since the thickness of the base 21 is greater than the height of the first vertical plate 1331, when the energy storage unit 20 is assembled in the installation, Fig. 9 and Fig.10As shown, the edge of the rear end of the base 21 of the energy storage unit 20 can be brought into contact with the guide section 1333 on the first inclined plate 1332 , and the first inclined plate 1332 limits the step surface of the base 21 of the energy storage unit 20 in the height direction H of the cabinet 11 .

[0082] Among them, for the case where the distance between the guide segment 1333 on the first guide rail 131 and the guide segment 1333 on the second guide rail 132 decreases in the direction from the front end 1314 of the support plate to the rear end 1315 of the support plate, that is, the distance between the end of the guide segment 1333 on the first guide rail 131 and the guide segment 1333 on the second guide rail 132 close to the front end 1314 of the support plate and the corresponding warehouse wall is less than the distance between the end away from the front end 1314 of the support plate and the corresponding warehouse wall.

[0083] Alternatively, if Figure 8 As shown, the guide segment 1333 is a straight segment structure. Of course, the guide segment 1333 can also be an arc segment structure, etc., and the implementation of the present application does not limit this.

[0084] In some embodiments, Figure 8 As shown, the surface of the first inclined plate 1332 facing the support surface 1312 has an elastic buffer pad 1336. In this way, by setting the elastic buffer pad 1336, the distance between the first inclined plate 1332 and the base 21 of the energy storage unit 20 can be reduced, and based on the elastic buffering of the elastic buffer pad 1336 itself, the hard contact between the first inclined plate 1332 and the energy storage unit 20 can be avoided, and based on the buffer space formed by the elastic buffer pad 1336 in the depth direction S of the cabinet 11, it can be suitable for limiting the energy storage unit 20 with a base 21 of different widths (i.e., the size along the depth direction S of the cabinet 11), thereby further improving the applicability of the energy storage cabinet 10.

[0085] In some embodiments, the angle formed by the first inclined plate 1332 and the first vertical plate 1331 toward the front end 1314 of the support plate is a right angle; Figure 8 As shown, the angle formed by the first inclined plate 1332 and the surface of the first vertical plate 1331 toward the front end 1314 of the support plate can also be an obtuse angle α1, thereby avoiding interference between the base 21 (with a relatively thin thickness) and the first inclined plate 1332 when the base 21 abuts against the first vertical plate 1331.

[0086] In some embodiments, an elastic buffer is attached to the front end of the first vertical plate 1331 near the first guide rail 131. In this way, the elastic buffer of the elastic buffer itself can avoid hard contact between the first vertical plate 1331 and the energy storage unit 20, and the buffer space formed by the elastic buffer in the depth direction S of the cabinet 11 can be used to limit the energy storage unit 20 with bases 21 of different widths (i.e., the size along the depth direction S of the cabinet 11), thereby further improving the applicability of the energy storage cabinet 10.

[0087] Optionally, the elastic buffer is a compression spring, elastic buffer cotton, etc. Of course, it can also be other elastic buffer structures, which are not limited in the embodiments of the present application.

[0088] In some embodiments, Fig.11 and Fig.12 As shown, the limiting portion 133 further includes a second vertical plate 1334, which is attached to the side of the first vertical plate 1331 close to the front end 1314 of the support plate and connected to the first vertical plate 1331. In this way, the position of the limiting surface for limiting the rear end of the energy storage unit 20 can be adjusted by setting the second vertical plate 1334, that is, Fig.12 As shown, the rear end of the energy storage unit 20 is limited by the second vertical plate 1334 on the basis of the first vertical plate 1331 .

[0089] Optionally, the second vertical plate 1334 is detachably connected to the first vertical plate 1331, thereby facilitating the limiting of energy storage units 20 with bases 21 having different widths (i.e., the dimensions along the depth direction S of the cabinet body 11), that is, the energy storage unit 20 with a shorter base 21 is limited by the second vertical plate 1334, or after the second vertical plate 1334 is removed, the energy storage unit 20 with a longer base 21 is limited by the first vertical plate 1331, so as to improve the applicability of the energy storage cabinet 10.

[0090] Optionally, an elastic buffer is attached to the front end of the second vertical plate 1334 near the first guide rail 131. In this way, the elastic buffer of the elastic buffer itself can avoid hard contact between the second vertical plate 1334 and the energy storage unit 20, and the buffer space formed by the elastic buffer in the depth direction S of the cabinet 11 can be used to limit the energy storage unit 20 with bases 21 of different widths (i.e., the size along the depth direction S of the cabinet 11), thereby further improving the applicability of the energy storage cabinet 10.

[0091] In some embodiments, Fig.11 and Fig.12As shown, the limiting portion 133 further includes a second inclined plate 1335, which is connected to the side of the second vertical plate 1334 away from the support surface 1312, and the second inclined plate 1335 is inclined away from the side of the second vertical plate 1334 toward the front end 1314 of the support plate. In this way, by setting the second inclined plate 1335, the base 21 on the energy storage unit 20 can be limited in the height direction H of the cabinet 11, that is, the energy storage unit 20 can be limited in the height direction H of the cabinet 11 to ensure the stability of the energy storage unit 20 when assembled on the mounting frame 13.

[0092] The first vertical plate 1331 and the first inclined plate 1332 may be an integrated structure or a structure in which adjacent sides are fixedly connected. Fig.12 As shown, the angle formed by the second inclined plate 1335 and the second vertical plate 1334 toward the surface of the front end 1314 of the support plate is a right angle α2; of course, the angle formed by the second inclined plate 1335 and the second vertical plate 1334 toward the surface of the front end 1314 of the support plate can also be an obtuse angle, and the implementation manner of the present application does not limit this.

[0093] Optionally, the surface of the second inclined plate 1335 facing the support surface 1312 has an elastic buffer pad 1336. In this way, by providing the elastic buffer pad 1336, the distance between the second inclined plate 1335 and the base 21 of the energy storage unit 20 can be reduced, thereby improving the stability of the second inclined plate 1335 limiting the base of the energy storage unit 20 in the height direction H of the cabinet 11; at the same time, based on the elastic buffer of the elastic buffer pad 1336 itself, the hard contact between the second inclined plate 1335 and the energy storage unit 20 can be avoided.

[0094] In some embodiments, such as Figure 7 As shown, the first guide rail 131 further includes a side plate 1313 , the side plate 1313 is fixedly connected to the first warehouse wall 1121 , and the support plate 1311 is fixedly connected to the side plate 1313 .

[0095] Optionally, the side plates 1313 and the support plates 1311 may be L-shaped plates of an integrated structure to reduce the number of structural parts. Further, the first guide rail 131 includes two L-shaped plates, the side plates 1313 on the two L-shaped plates are fixedly connected to the first warehouse wall 1121, and the support plates 1311 of the two L-shaped plates are arranged back to back to ensure the stability of the support plates 1311 supporting the energy storage unit 20.

[0096] In addition, the first vertical plate 1331 arranged on the supporting surface 1312 of the supporting plate 1311 can be fixed on the supporting surface 1312 of the supporting plate 1311, and can also be fixed on the surface of the side plate 1313 away from the first warehouse wall 1121; and the first vertical plate 1331 and the side plate 1313 can be perpendicular to each other.

[0097] Optionally, for the fixing portion 134 at the front end 1314 of the support plate, the front end of the support plate 1311 may be folded toward the side away from the support surface 1312, so that the fixing portion 134 is formed by the folded plate at the front end of the support plate 1311, or the front end of the side plate 1313 may extend out of the battery compartment 112 and be folded toward the side close to the first compartment wall 1121, so that the fixing portion 134 is formed by the folded plate at the front end of the side plate 1313. Compared with the case where the fixing portion 134 is formed at the front end of the support plate 1311, the fixing portion 134 is formed at the front end of the side plate 1313, so that possible interference when assembling the energy storage unit 20 on the lower mounting frame 13 can be avoided.

[0098] It should be noted that the fixing portion 134 at the front end 1314 of the support plate can be a structural member that is integrated with the support plate 1311 or the side plate 1313, or it can be a structural member that is separately fixed to the front end of the support plate 1311 or a structural member that is fixed to the front end of the side plate 1313. The implementation manner of the present application does not limit this.

[0099] In the embodiment of the present application, after the energy storage unit 20 is supported on the mounting frame 13, the front end of the energy storage unit 20 and the fixing portion 134 of the first guide rail 131 can be located in the same plane under the adjustment of the limiting portion 133 (the limiting of the first vertical plate 1331 and the second vertical plate 1334, or the limiting of the guide section 1333 on the first inclined plate 1332). It is also possible that the front end of the energy storage unit 20 and the fixing portion 134 of the first guide rail 131 are not in the same plane.

[0100] At this time, the front end of the energy storage unit 20 can be directly fixedly connected to the fixing part of the front end 1314 of the support plate by means of locking bolts. Of course, the front end of the energy storage unit 20 can also be fixedly connected to the fixing part of the front end 1314 of the support plate by other means.

[0101] In some embodiments, Fig.13 and Fig.14 As shown, the energy storage cabinet 10 further includes a first locking member 135, the first locking member 135 having a first locking portion 1351, the first locking portion 1351 being fixedly connected to the fixing portion 134 on the first rail 131 or the second rail 132, and being used to be fixedly connected to the energy storage unit 20. In this way, the energy storage unit 20 can be assembled and fixed on the mounting frame 13 by the first locking member 135.

[0102] For example, Fig.13 and Fig.14As shown, the energy storage cabinet 10 includes two first locking members 135, a first locking portion 1351 on one first locking member 135 is fixedly connected to the fixed portion 134 on the first guide rail 131 (i.e., the folding plate at the front end of the side plate 1313 included in the first guide rail 131) and the front end of the energy storage unit 20, and a first locking portion 1351 on the other first locking member 135 is fixedly connected to the fixed portion 134 on the second guide rail 132 (i.e., the folding plate at the front end of the side plate 1313 included in the second guide rail 132) and the front end of the energy storage unit 20, so as to achieve fixed assembly of the energy storage unit 20 at the front end of the first guide rail 131 and the front end of the second guide rail 132.

[0103] Optionally, the first locking member 135 further includes a flange disposed on a side of the first locking portion 1351 , so as to improve the structural strength of the first locking member 135 and improve the stability of fixing the energy storage unit 20 .

[0104] In other embodiments, Fig.15 and Fig.16 ,or Fig.17 and Fig.18 As shown, the energy storage cabinet 10 also includes a second locking member 136, which has a second locking portion 1361, a third locking portion 1362 and a connecting portion 1363, the second locking portion 1361 and the third locking portion 1362 are not coplanar, and the connecting portion 1363 connects the second locking portion 1361 and the third locking portion 1362.

[0105] Alternatively, if Fig.16 As shown, the second locking portion 1361 is connected to the fixing portion 134 on the first guide rail 131 or the second guide rail 132, and the third locking portion 1362 is used to be fixedly connected to the energy storage unit 20, so as to achieve a fixed connection between the energy storage unit 20 and the fixing portion 134 when the fixing portion 134 and the front end of the energy storage unit 20 are not coplanar through the second locking portion 1361 and the third locking portion 1362 of the second locking member 136.

[0106] For example, Fig.15 and Fig.16As shown, the energy storage cabinet 10 includes two second locking members 136, a second locking portion 1361 on one second locking member 136 is fixedly connected to the fixed portion 134 on the first guide rail 131 (i.e., the folding plate at the front end of the side plate 1313 included in the first guide rail 131), and the third locking portion 1362 is fixedly connected to the front end of the energy storage unit 20, and the second locking portion 1361 on the other second locking member 136 is fixedly connected to the fixed portion 134 on the second guide rail 132 (i.e., the folding plate at the front end of the side plate 1313 included in the second guide rail 132), and the third locking portion 1362 is fixedly connected to the front end of the energy storage unit 20, so as to realize the fixed assembly of the energy storage unit 20 at the front end of the first guide rail 131 and the front end of the second guide rail 132.

[0107] Of course, for the second locking member 136 including the second locking portion 1361 and the third locking portion 1362, the energy storage unit 20 can also be fixedly connected with the fixing portion 134 when the fixing portion 134 is coplanar with the front end of the energy storage unit 20, that is, the second locking portion 1361 or the third locking portion 1362 on the second locking member 136 is respectively fixedly connected with the fixing portion 134 on the first guide rail 131 or the second guide rail 132 and the front end of the energy storage unit 20, thereby improving the applicability of fixing the front end of the energy storage unit 20 on the mounting frame 13, thereby further improving the applicability of the energy storage cabinet 10.

[0108] For example, Fig.17 and Fig.18 As shown, the fixing portion 134 of the first guide rail 131 is coplanar with the front end of the energy storage unit 20. At this time, the third locking portion 1362 on the second locking member 136 is fixedly connected to the fixing portion 134 of the first guide rail 131 and the front end surface of the energy storage unit 20 respectively.

[0109] Therefore, in the present application, for the second locking member 136 including the second locking portion 1361 and the third locking portion 1362, the energy storage unit 20 can be fixedly connected when the fixing portion 134 is coplanar with the front end of the energy storage unit 20, and the energy storage unit 20 can be fixedly connected when the fixing portion 134 is not coplanar with the front end of the energy storage unit 20, thereby further improving the applicability of the energy storage cabinet 10.

[0110] Optionally, the third locking portion 1362 on the second locking member 136 is fixedly connected to the front end of the energy storage unit 20, and the third locking portion 1362 has a first through hole and a second through hole; the opening sizes of the first through hole and the second through hole are different. In this way, by setting the first through hole and the second through hole with two different opening sizes, the second locking member 136 can be matched with two different types of energy storage units 20, so as to achieve the applicability of the energy storage cabinet 10.

[0111] For example, for Figure 4The energy storage unit 20 shown in FIG. 1 can be provided with an M8 locking bolt which passes through the first through hole on the third locking portion 1362 and is fixedly connected to the front end of the energy storage unit 20; Figure 5 The energy storage unit 20 shown can use an M6 locking bolt to pass through the second through hole on the third locking portion 1362 and be fixedly connected to the front end of the energy storage unit 20. Of course, the first through hole and the second through hole on the third locking portion 1362 can also be other opening sizes, for example, the first through hole on the third locking portion 1362 is suitable for an M10 locking bolt, and the second through hole is suitable for an M8 locking bolt.

[0112] In addition, the second locking portion 1361 and the third locking portion 1362 are both provided with a third through hole, and the third through hole is used to match the fixing portion 134 on the first guide rail 131. In this way, the third through hole on the second locking portion 1361 and the first through hole on the third locking portion 1362 can be used to achieve the fixed assembly of one type of energy storage unit 20 on the mounting frame 13; the second through hole and the third through hole on the third locking portion 1362 can be used to achieve the fixed assembly of another type of energy storage unit 20 on the mounting frame 13.
