Detailed Implementation

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0059] In the description of this application, it should be understood that the terms "height," "thickness," "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, and "at least one" can mean one, two, or more, unless otherwise expressly specified.

[0060] It should also be noted that in the accompanying drawings of the embodiments of this application, the arrow marked X represents the first direction X, the arrow marked Y represents the second direction Y, and the arrow marked Z represents the third direction Z. The first direction X, the second direction Y, and the third direction Z are introduced to more clearly illustrate the structure and relative positional relationship of each component in the energy storage device. In practical applications, the first direction X, the second direction Y, and the third direction Z may change depending on the placement of the energy storage device.

[0061] This application provides an energy storage device; please refer to [link / reference]. Figure 1 and Figure 11 The energy storage device has a first direction X, a second direction Y, and a third direction Z that intersect each other. The first direction X corresponds to the length direction of the energy storage device, the second direction Y corresponds to the width direction of the energy storage device, and the third direction Z corresponds to the height direction of the energy storage device.

[0062] Please see Figure 1 and Figure 11 The energy storage device includes a battery compartment 1 and a comprehensive compartment 2. The battery compartment 1 contains multiple battery modules arranged along a third direction Z. The comprehensive compartment 2 is located on one side of the battery compartment 1 along a first direction X. The comprehensive compartment 2 includes a power compartment 21 and an electrical compartment 22 arranged along a second direction Y. The power compartment 21 contains multiple energy storage converters 211 arranged along a third direction Z. The electrical compartment 22 can be used to house one or more of the following: fire cylinders 201, electrical integration boxes 202, AC circuit breakers 203, and copper busbars 204. The electrical integration box 202 includes control boxes and switches, forming a comprehensive structure composed of multiple electrical components.

[0063] Please see Figure 1 and Figure 2The integrated storage unit 2 includes an upper frame 27, a lower frame 28, and multiple columns. The upper frame 27 and lower frame 28 are spaced apart in the third direction Z. The multiple columns are divided into multiple groups, with two columns in each group, and are spaced apart along the first direction X. The multiple groups of columns are connected between the upper frame 27 and the lower frame 28. The multiple groups of columns are divided into a first column group 291, a second column group 292, and a third column group 293, which are spaced apart along the second direction Y. The first column group 291, the second column group 292, the upper frame 27, and the lower frame 28 enclose a power room 21. The second column group 292, the third column group 293, the upper frame 27, and the lower frame 28 enclose an electrical room 22. The second column group 292 is a partition structure for the internal space of the integrated storage unit 2. The integrated storage unit 2 also includes a panel 294, which covers the outside of the frame structure formed by the upper frame 27, the lower frame 28, and the multiple columns, so that the interior of the integrated storage unit 2 forms a relatively enclosed space. The doors, inspection ports, and other structures of the integrated warehouse 2 are also located on panel 294.

[0064] In related technologies, energy storage devices, for reasons of functional independence, supply chain optimization, and heat dissipation, often have the energy storage converter 211 housed in a separate cabinet, i.e., a PCS cabinet. This type of energy storage device results in a spatially dispersed layout and requires cross-cabinet wiring, increasing cable length and space occupation. This embodiment integrates the energy storage converter 211 into the power compartment 21 of the integrated compartment 2, and arranges it side-by-side with the electrical compartment 22 along the second direction Y. This avoids the spatial dispersion of the structure and cross-cabinet wiring, shortening wiring distance and reducing space occupation. The battery compartment 1 and integrated compartment 2 are arranged along the first direction X, while the power compartment 21 and electrical compartment 22 are arranged along the second direction Y, making the equipment more compact and improving space utilization. Furthermore, compared to placing the energy storage converter 211 in the battery compartment 1, this embodiment avoids occupying the internal space of the battery compartment 1, allowing the battery compartment 1 to be dedicated to arranging battery modules. By improving the space utilization of the battery compartment 1, the energy density of the energy storage device is increased. Furthermore, the available space in the integrated compartment 2 is relatively ample, facilitating the installation and maintenance of the energy storage converter 211 without frequent access to the battery compartment 1. In addition, separating the energy storage converter 211 from the battery compartment 1 can, on the one hand, reduce the impact of battery thermal runaway on the energy storage converter 211, and prevent high temperatures, arcing, or electrical faults from directly contacting the battery; on the other hand, it helps maintain their respective heat dissipation environments and reduces mutual electromagnetic interference.

[0065] Please see Figure 1 and Figure 2In some embodiments, the electrical room 22 is provided with a partition 220, which divides the interior space of the electrical room 22 into a fire protection zone 221, a control zone 222, and an AC wiring zone 223 arranged along a third direction Z. Specifically, the partition 220 includes multiple crossbars 2201, which are divided into multiple groups and arranged at intervals along a third direction Z. Each group contains multiple crossbars 2201, which are distributed on a plane formed by a first direction X and a second direction Y. At least one crossbar 2201 is connected to a second column group 292, and at least another crossbar 2201 is connected to a third column group 293. Each group of crossbars 2201 serves as a partition structure or partition marker, so that the electrical room 22 is divided into the fire protection zone 221, the control zone 222, and the AC wiring zone 223 with reference to the partition 220.

[0066] Fire cylinder 201 is located in fire protection zone 221, electrical integration box 202 is located in control zone 222, and AC circuit breaker 203 and copper busbar 204 are located in AC wiring zone 223. By further dividing the electrical room 22, the internal components can be categorized, maximizing space utilization. This reduces mutual interference between zones and facilitates quick location of target areas, minimizing operational errors.

[0067] Please see Figure 1 In some embodiments, along the third direction Z, the fire protection zone 221, control zone 222, and AC wiring zone 223 are arranged sequentially from top to bottom. Placing the AC wiring zone 223 at the lowest point along the third direction Z facilitates the wiring of AC cables to the copper busbars within the AC wiring zone 223, and also facilitates the routing of AC cables from the lowest point of the entire energy storage device, thereby reducing cable length.

[0068] The control area 222 is located at a mid-height level, close to the height when people are standing, which makes it convenient for people to open the door to inspect and maintain the electrical switches inside.

[0069] The fire sprinkler system of the energy storage device is located on top of the battery system. Therefore, placing the fire zone 221 at the top position can reduce the length of the fire pipeline and save space. In addition, the maintenance and replacement cycle of the fire cylinder 201 is relatively long, and this position can minimize the interference with daily maintenance operations.

[0070] Please see Figure 1 In some embodiments, a first heat dissipation component 23 is provided inside the electrical compartment 22. The first heat dissipation component is used to dissipate heat from some or all areas inside the electrical compartment 22 to maintain the ambient temperature in the corresponding area and increase electrical safety.

[0071] Please see Figure 2 and Figure 3In some embodiments, the first heat dissipation component 23 includes a fan coil unit 231, which is located within the fire protection zone 221. The fire protection zone 221 typically requires reserved safety space, thus the fan coil unit 231 can fully utilize the internal space of the fire protection zone 221. The fan coil unit 231 has a return air inlet 2311 and an air outlet 2312. One of the return air inlet 2311 and the air outlet 2312 corresponds to the fire protection zone 221, and the other corresponds to the control zone 222, thereby forming an airflow circulation between the fire protection zone 221 and the control zone 222 for circulating heat dissipation between the two zones.

[0072] Specifically, the fan coil unit 231 includes a casing, a coil, a third fan, and a chiller. An air outlet 2312 and a return air outlet 2311 are located on the casing, while the coil and the third fan are housed inside the casing. During operation, the chiller provides low-temperature water that flows into the coil, and the third fan forces airflow through the low-temperature coil. The cooled air is then blown out, achieving heat dissipation for the target area.

[0073] In this embodiment, the fire protection zone 221 is located above the control zone 222, the return air vent 2311 corresponds to the control zone 222, and the air outlet vent 2312 corresponds to the fire protection zone 221. High-temperature air naturally rises to the fire protection zone 221, is drawn in and cooled by the fan coil unit 231 through the return air vent 2311, and then the cooled air is blown from the air outlet 2312 towards the fire protection zone 221 before naturally sinking back to the control zone 222, forming a closed-loop airflow circulation. This reduces energy consumption and improves heat dissipation efficiency, while also preventing cold air from directly blowing onto sensitive equipment within the control zone 222, reducing the risk of condensation.

[0074] Please see Figure 3 In some embodiments, the fan coil unit 231 has a baffle 2313 at the air outlet 2312. The baffle 2313 has a guide port 2314 communicating with the air outlet 2312, and the width of the guide port 2314 is smaller than the width of the air outlet 2312. In this embodiment, the guide port 2314 and the air outlet 2312 are both located on the same side of the housing along the second direction Y, and the widths of the guide port 2314 and the air outlet 2312 are their respective dimensions along the third direction Z. When the airflow is blown out through the guide port 2314, the airflow velocity increases because the cross-sectional area of ​​the guide port 2314 intersects with the cross-sectional area of ​​the air outlet 2312, which is smaller. This increases the airflow path, thereby expanding the coverage area of ​​the cold airflow and improving the heat dissipation effect.

[0075] In this embodiment, the airflow inlet 2314 is positioned towards the fire cylinder 201, and the energy storage converter 211 is also located on the airflow path from the airflow inlet 2314. Therefore, some of the airflow can enter the power chamber 21 to dissipate heat from the energy storage converter 211, increasing the coverage area of ​​the fan coil unit 231. In other embodiments, the fan coil unit 231 can also be installed in different locations within the fire protection zone 221, provided that the space allows.

[0076] Please see Figure 3 In some embodiments, an inclined guide surface 2315 is provided inside the wind shield 2313. The guide surface 2315 extends downward at an inclination from the guide port 2314, and is used to allow condensate at the guide port 2314 to slide down into the wind shield 2313. In this embodiment, the guide surface 2315 is set at an angle to the third direction Z, and the vertical distance between the guide surface 2315 and the housing in the second direction Y decreases along the direction away from the guide port 2314, so that the downward inclined side of the guide surface 2315 is close to the air outlet 2312. When the condensate generated inside the housing moves to the guide port 2314, the condensate slides down along the guide surface 2315 and is collected under the action of gravity, reducing the possibility of condensate entering the electrical chamber 22 and improving the overall electrical safety of the equipment.

[0077] To facilitate the collection and treatment of condensate, a water collection tray can be arranged inside the shell, positioned below the coil and corresponding to the downward-sloping end of the guide surface 2315.

[0078] Please see Figure 2 In some embodiments, the fan coil unit 231 is located on the side of the fire protection zone 221 away from the power room 21. The fan coil unit 231 is located in the outer edge area of ​​the fire protection zone 221, close to the panel 294 of the integrated compartment 2, which facilitates the installation of a window structure on the panel 294 of the integrated compartment 2, making it convenient for the inspection and maintenance of the fan coil unit 231.

[0079] Please see Figure 4 In some embodiments, the first heat dissipation assembly 23 includes multiple first fans 232, with at least one first fan 232 installed in each of the fire protection zone 221, control zone 222, and AC wiring zone 223. Each zone is cooled by airflow drawn by the first fans 232, enabling targeted heat dissipation to prevent heat accumulation and localized overheating, thus reducing the risk of fire or equipment failure. The first fans 232 are relatively small in size, reducing space requirements and prioritizing the layout of components within each zone. Furthermore, the first fans 232 have low power consumption, contributing to reduced energy consumption.

[0080] Please see Figure 4In some embodiments, the axes of each first fan 232 are arranged in the same direction; or, the axes of at least one first fan 232 are arranged in different directions from the axes of at least another first fan 232. The axis of the first fan 232 is in the direction of the central rotation axis of its rotating impeller, that is, the main direction of the airflow drawn in and blown out by the first fan 232. By defining the blowing direction of each first fan 232, the heat dissipation requirements under different operating conditions can be met, providing high flexibility.

[0081] When all the first fans 232 are arranged in the same direction, directional airflow can be formed in the fire zone 221, control zone 222 and AC wiring zone 223.

[0082] For example, the axis of each first fan 232 is set along the second direction Y, and the airflow path of each first fan 232 can flow through the power chamber 21 to achieve heat dissipation of the electrical chamber 22 and the power chamber 21.

[0083] For example, the axis of each first fan 232 is set along the third direction Z. In two adjacent and interconnected regions, the first fan 232 can realize airflow relay, enhance airflow, and thus enhance the heat dissipation effect.

[0084] When the axis of at least one first fan 232 is set in a different direction from the axis of at least another first fan 232, the first fan 232 can blow air to the high-temperature area in a targeted manner to enhance the heat dissipation of the high-temperature area; or, when the areas where each first fan 232 is located are interconnected, by adjusting the axis direction of each first fan 232, airflow circulation in space can be achieved, which helps to reduce heat dissipation dead zones.

[0085] Please see Figure 4 In some embodiments, the fire zone 221, control zone 222, and AC wiring zone 223 are arranged from top to bottom along the third direction Z. A first fan 232 is located at the top of the fire zone 221 and is configured to blow air upwards or downwards along the third direction Z. Since hot air rises naturally, at least some of the hot air in the control zone 222 and AC wiring zone 223 will converge into the fire zone 221. Therefore, in this embodiment, it is preferable that the first fan 232 blows air downwards along the third direction Z. The first fan 232 can forcibly draw the hot air at the top of the fire zone 221 downwards to prevent heat from accumulating at the top of the fire zone 221 and causing local overheating, thereby improving the safety of the equipment.

[0086] The first fan 232 is installed at the top of the fire-fighting zone 221. Located at the point where hot air accumulates, it can quickly and comprehensively draw hot air downwards, reducing the retention of hot air. In addition, the downward airflow generated by the first fan 232 can be discharged uniformly through the air ducts inside the integrated compartment 2, eliminating the need for a separate exhaust window and thus increasing the overall protection level of the equipment.

[0087] In some other embodiments, the first fan 232 can also be configured to blow air upwards, and a corresponding window structure is configured on the plate 294 of the integrated compartment 2 to exhaust hot air. In this case, the first fan 232 can make full use of the rising airflow of hot air and reduce the power loss of the first fan 232.

[0088] Please see Figure 4 In some embodiments, the first fan 232 located in the control area 222 is configured to blow air along the second direction Y, that is, the first fan 232 can blow air towards the power chamber 21 along the second direction Y, or blow air away from the power chamber 21. In this embodiment, the first fan 232 is located on the side of the electrical integration box 202 away from the power chamber 21, and the first fan 232 blows air towards the power chamber 21. Therefore, after the airflow first blows air to the electrical integration box 202 to dissipate heat, some of the airflow can also flow into the power chamber 21, carrying away some of the heat from the energy storage converter 211, thus improving the utilization rate of the first fan 232 in the control area 222. In addition, the airflow generated by the first fan 232 can also prevent hot air in the power chamber 21 from entering the control area 222, thereby reducing the impact on the devices in the control area 222.

[0089] In some other embodiments, the first fan 232 corresponding to the control area 222 can also be located between the power room 21 and the electrical integration box 202, or located on one side of the electrical integration box 202 along the first direction X, as long as the first fan 232 does not interfere with the surrounding structure.

[0090] Please see Figure 4 In some embodiments, AC circuit breakers 203 and copper busbars 204 are arranged at intervals along a first direction X within the AC wiring area 223. A first fan 232, located between the AC circuit breakers 203 and copper busbars 204, is configured to blow air along the first direction X. The first fan 232 is close to the AC circuit breakers 203 and copper busbars 204, and the AC circuit breakers 203 and copper busbars 204 are located in the airflow path generated by the first fan 232, enabling rapid airflow and heat dissipation at a relatively close distance, thus improving the heat dissipation effect.

[0091] In this embodiment, the air outlet side of the first fan 232 faces the AC circuit breaker 203 to fully ensure the heat dissipation requirements and safety of the AC circuit breaker 203.

[0092] Please see Figure 5 In some embodiments, the first heat dissipation component 23 includes an air conditioning component 233, which is disposed opposite to the fire zone 221 and the control zone 222. The air conditioning component 233 has an air inlet side and an air outlet side, with the air inlet side corresponding to the fire zone 221 and the air outlet side corresponding to the control zone 222, and is located above the electrical integration box 202. The air conditioning component 233 includes an evaporator and a built-in fan. Air in the fire zone 221 is drawn in by the built-in fan and flows through the evaporator. The low-temperature liquid refrigerant in the evaporator absorbs heat from the air and vaporizes. The cooled air is then returned to the control zone 222, and this cycle repeats to cool the fire zone 221 and the control zone 222, achieving excellent cooling effect. It is understood that the components of the air conditioning component 233 may also include a compressor, a condenser, pipes, etc. Since the air conditioning component 233 is common knowledge in the art, it will not be described in detail here.

[0093] In order to reduce the space occupied by the air conditioning unit 233, the air conditioning unit 233 in this embodiment is installed on the door of the integrated compartment 2 (not shown in the figure), and the door corresponds to at least the fire zone 221 and the control zone 222.

[0094] Please see Figure 2 and Figure 6 In some embodiments, the integrated compartment 2 has a perforated area 24, which is spaced between the power compartment 21 and the electrical compartment 22 to connect them. Specifically, the perforated area 24 is formed by the upper frame 27, the lower frame 28, and the second column group 292. This facilitates the ventilation and heat dissipation of the electrical compartment 22 by the first heat dissipation component 23. During this process, a portion of the cooling airflow can directly enter the power compartment 21 through the perforated area 24, avoiding the need for additional structures such as air ducts, pipes, and windows to facilitate the flow of cooling air. This not only improves space utilization but also provides a channel for wiring between the energy storage converter 211 and the devices in the electrical compartment 22, thus shortening the wiring distance.

[0095] Please see Figure 6 In some embodiments, a first insulation component 2211 is provided within the fire protection zone 221, and the first insulation component 2211 is located on the side of the fire protection zone 221 near the open area 24. The first insulation component 2211 is one or more of insulation cotton, ceramic fiber board, and aerogel felt, which is used to block the transfer of heat from the power chamber 21 side to the fire protection zone 221, reduce the impact on the internal environment of the fire protection zone 221, and help maintain the heat dissipation effect of the first heat dissipation component 23.

[0096] Please see Figure 6In some embodiments, the partition 220 divides the portion of the hollow area 24 corresponding to the fire protection zone 221 into a first segment 241. The first segment 241 is also the portion of the hollow area 24 that faces the fire protection zone 221 in the second direction Y. In this embodiment, the partition 220 is only used as a reference for dividing the hollow area 24 and does not spatially partition the hollow area 24. In other embodiments, the partition 220 may also be at least partially disposed within the hollow area 24 to form a vertical spatial partition of the hollow area 24, thereby forming multiple independent sub-regions.

[0097] The first insulation element 2211 is installed on the first section 241. In the first direction X or the second direction Y, the exposed portion of the first insulation element 2211 is in the first section 241 so that the first section 241 is connected to the fire zone 221.

[0098] For example, the first insulation component 2211 has multiple sides in its circumferential direction. One of its sides in the first direction X is spaced apart from the plate 294 of the integrated compartment 2, and the orthographic projection of this side along the second direction Y falls on the first section 241. For ease of distinction, this side is referred to as the clearance surface. The upper side in the third direction Z is attached to the plate 294 of the integrated compartment 2, and the lower side is attached to or flush with the upper surface of the crossbar 2201 corresponding to the fire zone 221. In the remaining sides of the first insulation component 2211, each side is attached to the plate 294 or the upper frame 27 of the integrated compartment 2 to form an edge seal. This allows the first section 241 to communicate with the fire zone 221 through the clearance surface of the first insulation component 2211, so that smoke from the power room 21 side can enter the fire zone 221. A smoke alarm is installed in the fire zone 221, which can detect and alarm in time, improving equipment safety. In addition, the cooling airflow in the fire zone 221 can also enter the power room 21 through the clearance surface of the first insulation member 2211, thus improving the space utilization rate.

[0099] For example, the top surface of the first insulation component 2211 along the third direction Z is spaced apart from the plate 294 of the integrated compartment 2, and the orthographic projection of the top surface along the second direction Y falls on the first section 241; the bottom surface of the first insulation component 2211 along the third direction Z is attached to or flush with the upper surface of the crossbar 2201 corresponding to the fire zone 221; in the remaining sides of the first insulation component 2211, each side is attached to the plate 294 or the upper frame 27 of the integrated compartment 2 to form an edge seal, so that the first section 241 is connected to the fire zone 221 through the top surface of the first insulation component 2211 to realize smoke transmission and airflow.

[0100] In some other embodiments, the first insulation member 2211 can cover the entire first section 241, and the first insulation member 2211 has a window structure, through which the first insulation member 2211 exposes part of the first section 241.

[0101] Please see Figure 6 In some embodiments, the spacer 220 divides the portion of the cutout area 24 corresponding to the control area 222 into a second segment 242, which is also the portion of the cutout area 24 that corresponds directly to the control area 222 in the second direction Y. In this embodiment, the spacer 220 is only used as a reference for dividing the cutout area 24 and does not spatially separate the cutout area 24. Therefore, the first segment 241 and the second segment 242 are interconnected. In other embodiments, the spacer 220 may also be at least partially disposed within the cutout area 24 to form a vertical spatial separation of the cutout area 24, thereby forming independent first segments 241 and second segments 242.

[0102] A second insulation element 2221 is provided in the control area 222, and the second insulation element 2221 covers the second section 242. The second insulation element 2221 is one or more of the following: insulation cotton, ceramic fiber board, and aerogel felt. It is used to block the heat from the power chamber 21 side from being transferred to the control area 222. At the same time, it works with the first insulation element 2211 to increase the coverage of the hollow area 24, thereby improving the heat insulation effect.

[0103] Please see Figure 6 In some embodiments, the second insulation member 2221 exposes a second section 242 to communicate with the control area 222. In this embodiment, one side of the second insulation member 2221 in the first direction X is spaced apart from the plate 294 of the integrated compartment 2, and the orthographic projection of this side along the second direction Y falls on the second section 242. This allows the second insulation member 2221 to expose a second section 242 at that location, thereby communicating the second section 242 with the control area 222. This allows the cooling airflow of the control area 222 to flow through the energy storage converter 211, and also facilitates the entry of cables connected to the energy storage converter 211.

[0104] Furthermore, in the second direction Y, the width of the second insulation component 2221 exposed in the second section 242 is greater than the width of the first insulation component 2211 exposed in the first section 241, so as to provide relatively ample space for the connection cables of the energy storage converter 211. The portion of the second insulation component 2221 exposed in the second section 242 is located at the door of the integrated compartment 2 (not shown in the figure), which facilitates wiring and daily maintenance and repair.

[0105] Please see Figure 6In some embodiments, a third insulation element 2231 is provided within the AC wiring area 223. The third insulation element 2231 is located on the side of the AC wiring area 223 closest to the control area 222. The orthogonal projection of the third insulation element 2231 along the third direction Z can cover the control area 222. That is, the third insulation element 2231 spatially separates the AC wiring area 223 from the control area 222, sealing the bottom of the control area 222. The third insulation element 2231 is one or more of insulation cotton, ceramic fiber board, and aerogel felt. It blocks the transfer of heat from the AC wiring area 223 to the upper area, reducing interference with the devices in the control area 222.

[0106] Please see Figure 1 and Figure 7 In some embodiments, at least one temperature sensor 25 is installed in each of the fire protection zone 221, the AC wiring zone 223, and the power room 21. The temperature sensors 25 are positioned at the top of their respective areas and offset from the output position of the cooling airflow. The temperature sensor 25 in the power room 21 corresponds to the DC wiring side of the energy storage converter 211. Each temperature sensor 25 corresponds to a major temperature-sensitive area of ​​the equipment for targeted detection. Furthermore, since high-temperature gases naturally rise and tend to accumulate at the top, placing the temperature sensors 25 at the top of their respective areas allows for the earliest detection of abnormal temperature rises and timely alarm issuance. In addition, the sensors are offset from the output position of the cooling airflow to avoid direct exposure to cold air, which could lead to lower readings and thus increase the accuracy and reliability of the detection results.

[0107] Please see Figure 8 In some embodiments, a second heat dissipation assembly 26 is provided inside the power chamber 21. The second heat dissipation assembly 26 is used to dissipate heat from the power chamber 21 to maintain a stable and safe operating environment for the energy storage converter 211.

[0108] Please see Figure 8 In some embodiments, the second heat dissipation assembly 26 includes a plurality of second fans 261, the axes of each second fan 261 being arranged in the same direction; or, the axes of at least one second fan 261 are arranged in different directions from the axes of at least another second fan 261.

[0109] The axis of the second fan 261 is in the direction of the central rotation axis of its rotating impeller, which is the main direction of the airflow drawn in and blown out by the second fan 261. By limiting the blowing direction of each second fan 261, directional flow, multi-directional flow or circulating flow of cooling air can be achieved, which can meet the heat dissipation requirements under different operating conditions and has high flexibility.

[0110] Please see Figure 8In some embodiments, the side of the energy storage converter 211 furthest from the electrical compartment 22 is the DC side. The second heat dissipation assembly 26 includes a plurality of second fans 261, which are arranged at intervals along a third direction Z and are positioned opposite the DC side of the energy storage converter 211. The second fans 261 are configured to blow air along the third direction Z. Each second fan 261 blows air in succession along the third direction Z. When the airflow reaches the top, it is blocked and flows downward. When the airflow reaches the bottom of the power compartment 21, the blocked airflow is dispersed along a first direction X and forcibly drawn by the second fans 261, thus forming an airflow circulation, thereby dissipating heat from the DC side of the energy storage converter 211. The second fans 261 have a wide airflow coverage and a large flow rate.

[0111] Please see Figure 6 and Figure 8 Furthermore, each of the second fans 261 is positioned near the power chamber 21 along the first direction X to provide space for the installation and wiring of electrical components on the DC side. Furthermore, the exposed portion 24 of the first insulation member 2211 and the second insulation member 2221 along the first direction X is staggered from the second fan 261 in the first direction X. That is, on the plane formed by the first direction X and the second direction Y, the exposed portion of the exposed portion 24 of the hollow area 24 is arranged diagonally with the second fan 261. In this case, the cooling airflow blown from at least one of the fire protection zone 221 and the control zone 222 can enter the power chamber 21, corresponding to the portion of the energy storage converter 211 on the DC side away from the second fan 261, thus enhancing heat dissipation and reducing heat dissipation dead zones.

[0112] Please see Figure 9 and Figure 10 In some embodiments, a sealing plate 212 is provided inside the power chamber 21. The sealing plate 212 extends in the third direction Z and is located on the side of the energy storage converter 211 away from the electrical chamber 22. The sealing plate 212 and the energy storage converter 211 are arranged at intervals to form a wind chamber 213, and a second fan 261 is disposed inside the wind chamber 213. The wind chamber 213 restricts the movement space of the airflow driven by the second fan 261, which can reduce airflow dispersion and enable the airflow circulation to concentrate on dissipating heat from the DC side, thus helping to enhance the heat dissipation effect.

[0113] Please see Figure 10 and Figure 12In some embodiments, the sealing plate 212 abuts against the side of the DC circuit breaker 205 away from the energy storage converter 211, and is provided with a window structure that exposes part of the DC circuit breaker 205 to facilitate operation of the DC circuit breaker 205. The energy storage device also includes multiple DC circuit breakers 205, which are arranged at intervals along a third direction Z, and a first flow channel 2051 is formed between two adjacent DC circuit breakers 205. The multiple DC circuit breakers 205 divide the air chamber 213 into a second flow channel 2131 and a third flow channel 2132 arranged along a first direction X. The second flow channel 2131 and the third flow channel 2132 are respectively connected to the first flow channel 2051, and the second fan 261 is disposed in the second flow channel 2131.

[0114] Each of the second fans 261 blows air in succession along the third direction Z. The airflow in the second channel 2131 is blocked at the top and enters the third channel 2132 along the first direction X, moves downward, and then flows back to the second channel 2131 from the bottom of the third channel 2132, thus forming an airflow circulation around the entire DC side. Due to the limited internal space of the air chamber 213 and the high air pressure on the outlet side of the second fan 261, there is an air pressure difference between the second channel 2131 and the third channel 2132. Therefore, some of the airflow in the second channel 2131 on the outlet side of the second fan 261 will directly enter the third channel 2132 along the first channel 2051 and converge. At the same time, the airflow located in the third channel 2132 and near the bottom will enter the second channel 2131 along the first channel 2051, realizing the diversion and convergence of airflow, enhancing the heat dissipation effect, and the airflow in the first channel 2051 can also dissipate heat for the DC circuit breaker 205.

[0115] Please see Figure 8 and Figure 12 In some embodiments, the energy storage device further includes multiple shunts 206 and a battery control box 207, each arranged at intervals along a third direction Z. The shunts 206 are positioned between the battery control box 207 and the DC circuit breaker 205, and correspond to the second fan 261 in the second direction Y. The second fan 261 is positioned near the power chamber 21 along the first direction X to free up the main body space corresponding to the DC side for the DC circuit breaker 205 and the shunts 206. The battery control box 207 and the second fan 261 are arranged in the third direction Z, making full use of the side space. The battery control box 207 is located in the airflow path of the second fan 261, which can generate turbulence in the second fan 261, helping to accelerate the heat dissipation of the energy storage converter 211. In addition, the airflow in the first flow channel 2051 can also dissipate heat from the shunts 206, and the airflow in the second flow channel 2131 can dissipate heat from the battery control box 207.

[0116] Please see Figure 9In some embodiments, the sealing plate 212 is provided with multiple ventilation holes 2121. The ventilation holes 2121 allow the inside and outside of the air chamber 213 to communicate with each other, so as to prevent heat from circulating and accumulating inside the air chamber 213. In this embodiment, the ventilation holes 2121 correspond to the position of the second fan 261, so that the airflow can be exchanged between the inside and outside in a timely manner through the ventilation holes 2121.

[0117] Please see Figure 11 In some embodiments, the energy storage device further includes a temperature control compartment 3, which is located on one side of the integrated compartment 2 along the first direction X. The temperature control compartment 3 is used to house the liquid cooling unit. In this embodiment, the temperature control compartment 3, the battery compartment 1, and the integrated compartment 2 are arranged sequentially along the first direction X. In other embodiments, the temperature control compartment 3 may also be located between the battery compartment 1 and the integrated compartment 2, or it may be located on the side of the integrated compartment 2 away from the battery compartment 1. The specific arrangement can be selected according to different operating conditions, allowing for flexible layout.
