In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0041] The present application provides an energy storage integrated control cabinet 100 and an energy storage system 1 comprising the energy storage integrated control cabinet 100. As shown in the figure, the energy storage system 1 comprises an energy storage integrated control cabinet 100 and a container box 200. The energy storage integrated control cabinet 100 is arranged in the container box 200. Figure 1

[0042] Referring to Figures 2 to 7 , the energy storage integrated control cabinet 100 provided by the present application comprises a cabinet body 10, an AC / DC power distribution assembly 20, a DC bus main circuit 30 and a cable assembly 40. The accommodation space inside the cabinet body 10 comprises an uninterrupted power supply room 110, a power distribution room 120 and a wiring room 130 from top to bottom along the height direction. The AC / DC power distribution assembly 20 is arranged in the power distribution room 120; the DC bus main circuit 30 is arranged in the power distribution room 120 and located on one side of the AC / DC power distribution assembly 20 in the first direction X, and the first direction X is perpendicular to the height direction Z. The cable assembly 40 is connected with the DC bus main circuit 30 and passes out of the cabinet body 10 from the wiring room 130.

[0043] In the present application, the first direction X is specifically defined as the length direction of the cabinet body 10. The second direction Y is specifically the width direction of the cabinet body 10. As Figure 1 ​As shown, when the energy storage integrated control cabinet 100 is placed in the container box 200, the first direction X is consistent with the length direction of the container box 200, and the second direction Y is consistent with the width direction of the container box 200. The energy storage integrated control cabinet 100 is located at the entrance of the container box 200 in the length direction. The energy storage integrated control cabinet 100 and the liquid cooling unit 300 are arranged side by side along the width direction of the container box 200.

[0044] The accommodation space inside the cabinet body 10 is divided into an uninterruptible power supply room 110, a power distribution room 120, and a wiring room 130 from top to bottom; the parts can also be isolated by a partition. The uninterruptible power supply room 110 can be used to place an uninterruptible power supply.

[0045] The DC bus main circuit 30 can be used to connect the high-voltage box of the battery cluster in the container box 200, and then output DC power to the energy storage converter through the AC-DC power distribution assembly 20.

[0046] The AC-DC power distribution assembly 20 is also used to output AC power, which can be connected to an external power source and electrical equipment in the container box 200. The electrical equipment in the container box 200 includes lighting equipment, various sockets, and the liquid cooling unit 300. It can be understood that the AC-DC power distribution assembly 20 includes an AC control part and a DC power distribution part. The AC control part connects the external power source and the electrical equipment in the container box 200. The DC power distribution part is used to connect to the energy storage converter.

[0047] The above-mentioned energy storage integrated control cabinet 100 integrates the AC control part and the DC power distribution part, which saves the space in the width direction of the container box when assembled in the container box; at the same time, referring to Figure 7 , the DC bus main circuit 30 is located on one side of the AC-DC power distribution assembly 20 in the first direction X, which further saves the space in the width direction of the container box, thereby facilitating the liquid cooling unit 300 to increase the upper limit of its size design, and then facilitating the improvement of the energy density of the battery in the box.

[0048] In some embodiments, referring to Figure 8 and Figure 9 , the DC bus main circuit 30 includes two branch circuit assemblies 310 arranged along the second direction Y, the second direction Y, the first direction X, and the height direction Z are perpendicular to each other; each branch circuit assembly 310 includes a circuit breaker assembly 311, in each branch circuit assembly 310, the negative input copper bar 312 and the positive input copper bar 313 of the circuit breaker assembly 311 are arranged in the first direction X, and the negative output copper bar 314 and the positive output copper bar 315 are arranged in the second direction Y.

[0049] As described above, the DC bus main circuit 30 can be used to connect the high-voltage boxes of the battery cluster in the container box 200, and then output DC power to the energy storage converter through the AC-DC power distribution assembly 20. Generally, at least two high-voltage boxes are arranged in the container box 200. The high-voltage box is the core component in the energy storage system 1, and its role is not limited to the management and distribution of electric energy, but also includes system safety protection, battery management, and various test functions, to ensure the efficient, stable and safe operation of the energy storage system 1.

[0050] In this embodiment, the DC bus main circuit 30 is arranged to be connected with two high-voltage boxes. For this purpose, as shown in Figure 8 and Figure 9 , the DC bus main circuit 30 includes two branch circuit assemblies 310. Each branch circuit assembly 310 is used to connect the positive and negative poles of the high-voltage box and is connected with the energy storage converter. Specifically, the circuit breaker assembly 311 of the branch circuit assembly 310 includes a negative input copper bar 312 and a positive input copper bar 313, a negative output copper bar 314 and a positive output copper bar 315. Among them, the negative input copper bar 312 is used to be connected with the negative output terminal of the high-voltage box, and the positive input copper bar 313 is used to be connected with the positive output terminal of the high-voltage box. The negative output copper bar 314 and the positive output copper bar 315 are respectively used to be connected with the positive and negative input of the energy storage converter.

[0051] In order to save the size of the cabinet 10 in the second direction Y, in this embodiment, the negative input copper bar 312 and the positive input copper bar 313 are arranged in the first direction X, and the negative output copper bar 314 and the positive output copper bar 315 are arranged in the second direction Y. In this way, the negative input copper bar 312 and the positive input copper bar 313 can be arranged by using the space in the first direction X, thereby saving the size of the cabinet 10 in the second direction Y.

[0052] Further, the branch circuit assembly 310 includes an upper DC fuse 3111 and a lower DC fuse 3112 arranged in an up-down manner. The top and bottom of the upper DC fuse 3111 are respectively connected with the negative input copper bar 312 and the negative output copper bar 314, and the top and bottom of the lower DC fuse 3112 are respectively connected with the positive input copper bar 313 and the positive output copper bar 315.

[0053] As shown in Figure 8 and Figure 9As shown, the upper DC fuse 3111 and the lower DC fuse 3112 are staggered in the height direction Z. The negative input copper bar 312 is connected to the top of the upper DC fuse 3111, and the positive input copper bar 313 is connected to the top of the lower DC fuse 3112. The negative input copper bar 312 and the positive input copper bar are arranged in the first direction X as a whole. Similarly, the negative output copper bar 314 is connected to the bottom of the upper DC fuse 3111, and the positive output copper bar 315 is connected to the bottom of the lower DC fuse 3112. The negative output copper bar 314 and the positive output copper bar 315 are arranged in the second direction Y as a whole.

[0054] In the embodiment, the upper DC fuse 3111 and the lower DC fuse 3112 are staggered in the height direction, which can connect the copper bars and provide space for the arrangement of the negative input copper bar 312 and the negative output copper bar 314 in the first direction X, and for the arrangement of the negative output copper bar 314 and the positive output copper bar 315 in the second direction Y.

[0055] In some embodiments, with reference to Figure 4 The AC-DC power distribution assembly 20 includes an air switch group 210, a first output terminal row 220 and a second output terminal row 230 arranged on both sides of the air switch group 210, and the first output terminal row 220 is connected to the output end of the air switch group 210. An AC molded case circuit breaker group 240 is located above the air switch group 210, and the AC molded case circuit breaker group 240 includes two AC output ends, i.e., a first AC output end 241 and a second AC output end 242, which are connected to the input end and the second output terminal row 230 of the air switch group 210, respectively.

[0056] Specifically, in the second direction Y, the first output terminal row 220 and the second output terminal row 230 are located on both sides of the air switch group 210. When specifically arranged, the cabinet 10 is provided with plastic supports on the inner walls in the second direction Y to fix the first output terminal row 220 and the second output terminal row 230.

[0057] The air switch group 210 is short for air switch group. The air switch group 210 includes a plurality of air switches to deliver the output of the AC molded case circuit breaker group 240 to the first output terminal row 220, and then to the electrical equipment in the cabinet, such as lighting equipment, various sockets, and liquid cooling units 300, through the first output terminal row 220. It can be understood that the specific number of air switches depends on the number of electrical equipment to be loaded.

[0058] The AC molded case circuit breaker group 240 includes two AC output terminals, i.e., the output part thereof is divided into two paths. One path is connected to the input terminal of the air switch group 210, and the other path is connected to the second output terminal row 230, so that it can be transmitted to the liquid cooling unit 300 through the second output terminal row 230. Moreover, in the energy storage system 1, the second output terminal row 230 is arranged on the side of the cabinet 10 close to the liquid cooling unit 300, so that the wiring path between the second output terminal row 230 and the liquid cooling unit 300 is also relatively short.

[0059] In the embodiment, the first output terminal row 220 and the AC molded case circuit breaker group 240 are respectively connected to the air switch group 210 through a line, the second output terminal row 230 and the AC molded case circuit breaker group 240 are connected through a line, and the first output terminal row 220, the second output terminal row 230 and the AC molded case circuit breaker group 240 are arranged around the air switch group 210, so that the wiring paths of the connections are all relatively short.

[0060] In some embodiments, with reference to Figure 4 and Figure 7 The AC-DC power distribution assembly 20 further includes an AC input terminal row 260 located below the first output terminal row 220, a surge installation plate 250 arranged on one side of the AC input terminal row 260 and below the air switch group 210, and a DC surge module 251 and an AC surge module 252 installed on the surge installation plate 250. The incoming line end of the DC surge module 251 is connected to the output end of the DC bus main circuit 30, and the outgoing line end is connected to the second output terminal row 230. The incoming line end of the AC surge module is connected to the output end of the AC input terminal row 260, and the outgoing line end is connected to the input end of the AC molded case circuit breaker group 240.

[0061] The AC input terminal row 260 is specifically arranged on the same side of the cabinet 10 as the first output terminal row 220. The AC input terminal row 260 is used to access the external 220V power supply. The DC surge module 251 and the AC surge module 252 are both installed on the surge installation plate 250 and can be removed together with the surge installation plate 250, thereby facilitating maintenance. The DC bus main circuit 30 is specifically located on one side of the surge installation plate 250 in the first direction X.

[0062] Further, the lower end of the surge installation plate 250 is rotatably connected to the cabinet 10, and the upper end of the surge installation plate 250 is detachably connected to the cabinet 10.

[0063] Specifically, the lower end of the surge installation plate 250 is rotatably connected to the cabinet 10, for example, through a pivot, a hinge connection or the like. In this way, the surge installation plate 250 can be flipped over with the lower end as the rotation axis.

[0064] The upper end of the surge installation plate 250 is provided with a matching part which matches with the clamping mechanism 101 on the cabinet body 10. The specific mode of the clamping mechanism 101 is not limited, and it can lock or release the surge installation plate 250. For example, the clamping mechanism 101 includes a clamping block which can rotate. When the surge installation plate 250 is rotated to be parallel to the height direction, the clamping block can be moved to a position to block the surge installation plate 250.

[0065] In the embodiment, by enabling the surge installation plate 250 to be flipped, the maintenance of the elements thereon is facilitated. When maintenance is needed, the surge installation plate 250 can be flipped to the outside of the cabinet body 10, so that the direct-current surge module 251, the alternating-current surge module 252 and the like are moved to the outside of the cabinet body 10, the operation space is increased, and the maintenance is facilitated.

[0066] Further, as shown in Figure 4 、 Figure 7 , the power distribution chamber 120 of the cabinet body 10 is provided with a lower cabinet door 102 at a position corresponding to the surge installation plate 250, and is open at a position corresponding to the air switch group 210. The lower cabinet door 102 is used to protect the surge installation plate 250 and the elements thereon; and the open setting at the position corresponding to the air switch group 210 facilitates the operation of the air switch group 210. In this way, the structure of the cabinet body 10 is simplified, and the cost of the cabinet body 10 can be saved.

[0067] In some embodiments, as shown in Figure 2 、 Figure 7 、 Figure 10 , the power distribution chamber 120 is provided with a first partition plate 121 which separates the air switch group 210 from the lower part, the power distribution chamber 120 above the first partition plate 121 is open at the first front end face 103 of the cabinet body 10 in the first direction X, and a containing space is formed between the air switch group 210 and the first front end face 103.

[0068] The first partition plate 121 separates the air switch group 210 from the elements such as the surge installation plate 250 below, so that the power distribution chamber 120 is divided into a first chamber and a second chamber in the height direction. The first chamber is used to contain the air switch group 210, the first output terminal row 220, the second output terminal row 230 and the alternating-current molded case circuit breaker group 240, and the second chamber contains the alternating-current input terminal row 260, the surge installation plate 250 and the like.

[0069] In the embodiment, the first front end face 103 of the cabinet body 10 refers to the side of the cabinet body 10 which faces the outside when the integrated control cabinet is placed into the energy storage container box 200. The first chamber is open at the first front end face 103, and the first front end face 103 and the air switch group 210 have a containing space therebetween. The containing space is used to contain other devices in the box, so that the size in the length direction of the container is saved.

[0070] For example, the accommodating space can be used to accommodate the fire control host. In the container box 200, the space where the energy storage integrated control cabinet 100 and the liquid cooling unit 300 are located is usually constructed as an electrical cabin of the container-type energy storage system 1. The electrical cabin is provided with a cabin door, and the fire control host for monitoring the fire alarm information in the cabin is installed on the inner side of the cabin door. When the cabin door is closed, the cabin door is close to the first front end face 103 of the cabinet body 10, and the fire control host can be at least partially accommodated in the above-mentioned accommodating space, thereby saving the size in the length direction of the container.

[0071] Further, referring to Figure 4 , the first partition plate 121 is provided with a video monitoring recorder 122. The video monitoring recorder 122 is accommodated in the above-mentioned accommodating space and is supported by the first partition plate 121. In this way, the space in the height direction of the cabinet body 10 is fully utilized, and no other support structure is additionally added.

[0072] In some embodiments, referring to Figure 2 , Figure 5 , the outer side face of the cabinet body 10 is formed with a stepped portion 140 at the connection between the uninterruptible power supply chamber 110 and the power distribution chamber 120, and the stepped portion 140 is provided with a threading hole 141 which is in communication with the power distribution chamber 120 in the height direction Z.

[0073] The threading hole 141 extends through the stepped portion 140 in the height direction Z and is in communication with the first chamber of the power distribution chamber 120. One or more such threading holes 141 can be provided. In this way, the power supply line of the external power-using equipment can enter through the threading hole 141 and then be connected to the first output terminal row 220; thereby not affecting the placement of the elements in the uninterruptible power supply chamber 110. Further, the stepped portion 140 can be provided with multiple reinforcing ribs to increase the strength of the cabinet body 10.

[0074] In some embodiments, referring to Figure 5 , Figure 6 , Figures 10 to 13 , the energy storage integrated control cabinet 100 further comprises a mounting bracket 50. The mounting bracket 50 is arranged in the uninterruptible power supply chamber 110 and is used to support the uninterruptible power supply 60. The mounting bracket 50 comprises an upper bracket body 510 and a lower bracket body 520 which are connected as one body, and the upper bracket body 510 and the lower bracket body 520 are respectively formed with a placement space 530 in which the uninterruptible power supply 60 or the uninterruptible power supply host 70 is arranged.

[0075] The placing spaces 530 of the upper shelf body 510 and the lower shelf body 520 are respectively used to place one or more uninterruptible power supplies 60 or the uninterruptible power supply host 70. In the embodiment, the placing spaces 530 of the upper shelf body 510 are provided with the uninterruptible power supplies 60 or the uninterruptible power supply host 70 side by side along the second direction Y, and the placing spaces of the lower shelf body 520 are provided with two uninterruptible power supplies 60 side by side. The second direction Y is perpendicular to the first direction X, and the second direction Y, the first direction X and the height direction Z are perpendicular to each other.

[0076] In the embodiment, the mounting bracket 50 forms two layers of placing positions in the height direction Z of the cabinet body 10, so that the uninterruptible power supplies 60 or the uninterruptible power supply host 70 can be stacked in the height direction, thereby fully utilizing the space in the height direction of the cabinet body 10.

[0077] Further, with reference to Figure 2 、 Figure 10 and Figure 13 , in the first direction X, the second front end surface 511 of the upper shelf body 510 is flush with the first front end surface 103 of the cabinet body 10, and the third front end surface 521 of the lower shelf body 520 is recessed relative to the first front end surface 103 of the cabinet body 10 to form a mounting position, and the mounting position is provided with the control host 80 of the energy storage integrated control cabinet 100.

[0078] In addition, after the mounting bracket 50 is equipped in the uninterruptible power supply room 110, the second front end surface 511 of the upper shelf body 510 is flush with the first front end surface 103 of the cabinet body 10, and the third front end surface 521 of the lower shelf body 520 is recessed relative to the first front end surface 103 of the cabinet body 10 to form a mounting position. The mounting position is a mounting space for accommodating the control host 80 of the energy storage integrated control cabinet 100.

[0079] In the embodiment, by staggering the front end surfaces of the mounting bracket 50 up and down, space is left in the energy storage integrated control cabinet 100, so that the control host 80 can be mounted to the upper cabinet door 104 closing the uninterruptible power supply room 110, thereby achieving the purpose of solving the length direction space size of the cabinet body 10, and thereby facilitating the saving of the length direction size of the container body 200. After the upper cabinet door 104 closes the uninterruptible power supply room 110, the front side of the upper cabinet door 104 can be in a flush state.

[0080] In some embodiments, with reference to Figures 10 to 12At least one of the upper frame 510 and the lower frame 520 is connected to a load-bearing guide rail 540. The load-bearing guide rail 540 includes a fixed section 541 and a movable section 542 that are slidably connected. In the first direction X, the fixed section 541 is fixed to the cabinet 10, and the movable section 542 slidably cooperates with the fixed section 541 and is fixedly connected to the upper frame 510 or the lower frame 520. A locking structure 543 is provided at the front end of at least one of the movable sections 542. The locking structure 543 is used to cooperate with the cabinet 10 to secure the mounting bracket 50 within the uninterruptible power supply chamber 110.

[0081] Specifically, in this embodiment, the lower frame 520 is provided with support rails 540 on both sides thereof in the second direction Y. The fixed section 541 of the support rails 540 is fixedly connected to the inner wall of the cabinet 10. The movable section 542 slides with the fixed section 541. With this arrangement, the mounting bracket 50 is supported on the cabinet 10 via the support rails 540 and can slide relative to the cabinet 10 in the first direction X.

[0082] When the mounting bracket 50 is housed within the UPS compartment 110, the locking structure 543 engages with the cabinet 10 to secure the mounting bracket 50 within the UPS compartment 110. With this arrangement, when the UPS 60 needs to be inspected or repaired, the locking structure 543 can be released from the cabinet 10 and the entire mounting bracket 50 can be pulled outward.

[0083] Optionally, at least one movable segment 542 is provided, for example, two movable segments 542 are provided, one of the two movable segments 542 is connected to the fixed segment 541, and the other is provided with the aforementioned locking structure 543, and the two movable segments 542 are slidably engaged with each other. In this way, the degree to which the mounting bracket 50 can be pulled out of the uninterruptible power supply 60 can be increased.

[0084] In some embodiments, such as Figure 5 and Figure 6 As shown, the uninterruptible power supply room 110 and the distribution room 120 bracket are separated by a second partition 123, and there is a gap 105 between the bottom of the lower frame 520 and the second partition 123. The output cable (not shown) of the uninterruptible power supply host 70 can be partially stored in the gap 105.

[0085] The output cables of the uninterruptible power supply (UPS) 70 are connected to the circuit breaker assembly 210. In this embodiment, a gap 105 is provided between the bottom of the lower frame 520 and the second partition 123 to accommodate the output cables, ensuring sufficient clearance for the output cables to connect from the UPS 60 to the circuit breaker assembly 210. A hollow portion is provided in the second partition 123 to allow the output cables to extend into the power distribution chamber 120.

[0086] In some embodiments, reference Figure 6 、 Figure 12The upper shelf body 510 comprises an upper bottom plate 512, the lower shelf body 520 comprises a lower bottom plate 522 and a top plate 523, the upper bottom plate 512 is provided with a first through hole 513, the top plate 523 supports the lower bottom plate 522, and the lower shelf body 520 is provided with a second through hole 524 penetrating through the lower bottom plate 522 and the top plate 523. In the first direction X, the first through hole 513 and the second through hole 524 are both close to the rear end surface 106 of the cabinet body 10, and the second through hole 524 is in communication with the above-mentioned interval 105.

[0087] In the embodiment, the first through hole 513 and the second through hole 524 are respectively arranged on the upper bottom plate 512 and the lower bottom plate 522, so that the output cable of the uninterruptible power supply 60 can be led downward.

[0088] Specifically, referring to Figure 6 , Figure 12 The upper bottom plate 512 and the lower bottom plate 522 are both used to support the uninterruptible power supply 60 in the height direction Z. The top plate 523 is located below the upper bottom plate 512. In the first direction X, the first through hole 513 and the second through hole 524 are both close to the rear end surface 106 of the cabinet body 10, and the output cable (not shown) of the uninterruptible power supply 60 is led out from the rear end of the uninterruptible power supply 60, so that the output cable of the uninterruptible power supply 60 is sequentially led downward along the height direction, passes through the first through hole 513 and the second through hole 524, and then enters the above-mentioned interval 105 and the power distribution room 120.

[0089] In some embodiments, referring to Figure 12 and Figure 13 The upper shelf body 510 further comprises two upper side plates 514 arranged at intervals along the second direction Y and two upper limiting plates 515 arranged at intervals along the first direction X, the upper side plate 514 and the upper limiting plate 515 are both connected with the upper bottom plate 512 and enclose a top-opened placing space 530; in the height direction of the cabinet body 10, the height of the upper limiting plate 515 is less than the height of the upper side plate 514.

[0090] In the embodiment, the placing space 530 formed by the upper shelf body 510 is top-opened, which facilitates the installation and maintenance operation of the uninterruptible power supply 60 and the uninterruptible power supply host 70. Specifically, when the installation support 50 is pulled out of the uninterruptible power supply room 110, the operation can be performed from the top. Optionally, the top of the upper shelf body 510 is provided with a detachable cover plate (not marked). The cover plate can be assembled on the two upper side plates 514.

[0091] In addition, in the height direction Z, the height of the upper limiting plate 515 is less than the height of the upper side plate 514. In this way, when the uninterruptible power supply host 70 is assembled into the upper shelf body 510, the cable interface at the rear end of the uninterruptible power supply host 70 can be exposed to the outside, thereby facilitating the connection with the output cable.

[0092] In some embodiments, referring to Figure 12 and Figure 13 The lower shelf body 520 further comprises two lower side plates 525 arranged at intervals along the second direction Y, two lower limiting plates 526 arranged at intervals along the first direction X, the lower side plates 525, the lower limiting plates 526, the top plate 523 and the lower bottom plate 522 form a placement space 530; the lower side plates 525 and the upper side plates 514 are connected by the connecting plates 550.

[0093] The two lower limiting plates 526 constitute limiting in the first direction X, and the two lower side plates 525 constitute limiting in the second direction Y. The lower side plates 525 and the upper side plates 514 are connected by the connecting plates 550, so that the upper shelf body 510 and the lower shelf body 520 are connected as a whole, so as to slide together.

[0094] Further, the placement space 530 of the lower shelf body 520 further comprises two limiting columns 527 arranged at intervals along the second direction Y, the limiting columns 527 are fixedly connected to the lower bottom plate 522 in the height direction and support the top plate 523, and the two limiting columns divide the placement space 530 of the lower shelf body 520 into two parts in the second direction Y, each part constitutes a placement position, and each placement position is placed with an uninterruptible power supply 60. The limiting columns and the lower side plates 525 together limit the uninterruptible power supply 60 from both sides of the uninterruptible power supply 60.

[0095] In this way, the strength of the lower shelf body 520 is better, and the upper shelf body 510 can be better supported; and the two uninterruptible power supplies 60 in the lower shelf body 520 each have independent limiting in the second direction Y.

[0096] As shown in Figure 1 The application further provides an energy storage system 1, comprising a container body 200, a liquid cooling unit 300 arranged in the container body; the energy storage integrated control cabinet 100 is arranged in the container body 200 and is arranged side by side with the liquid cooling unit 300 in the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0097] Specifically, the first direction X is the length direction of the container body 200, and the second direction Y is the width direction of the container body 200. The energy storage integrated control cabinet 100 integrates an AC control part and a DC power distribution part, can meet the electrical control demand, and compared with the way of separately arranging a DC busbar cabinet and an AC power distribution cabinet in the prior art, when the energy storage integrated control cabinet 100 and the liquid cooling unit 300 are placed side by side in the container body 200 along the second direction Y, the space in the width direction of the container is saved. In addition, the DC busbar main circuit 30 is located on one side of the AC / DC power distribution assembly 20 in the first direction X, and the energy storage integrated control cabinet 100 itself is compact in the width direction, further saving the space in the width direction of the container, thereby facilitating the liquid cooling unit 300 to improve the upper limit of its size design, and then facilitating the improvement of the battery energy density in the container.
