The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0051] First reference Figure 1-Figure 9 The energy storage cabinet 1000 according to the second aspect of the utility model is described. Figure 1-Figure 9 As shown, the energy storage cabinet 1000 includes an energy storage housing 100 and an energy storage assembly 200 , and the energy storage assembly 200 is installed in the energy storage housing 100 .

[0052] Reference below Figure 1-Figure 9 An energy storage housing 100 according to an embodiment of the present invention is described.

[0053] like Figure 1-Figure 9As shown, the energy storage housing 100 according to the embodiment of the utility model includes: a cabinet 10 and an insulating structure 20 .

[0054] Specifically, the cabinet 10 has a first accommodating cavity 101 ; the insulating structure 20 is disposed in the first accommodating cavity 101 , and the insulating structure 20 is suitable for forming a second accommodating cavity, and the second accommodating cavity is suitable for accommodating the energy storage assembly 200 .

[0055] In this embodiment, an insulating structure 20 is provided in the first accommodating cavity 101 of the cabinet 10, and the energy storage assembly 200 is accommodated in the second accommodating cavity of the insulating structure 20, so that the energy storage assembly 200 and the cabinet 10 can be effectively and reliably insulated and separated by the insulating structure 20. When the energy storage housing 100 and the energy storage assembly 200 are assembled and arranged, since the insulating structure 20 plays a good role in insulating and protecting the energy storage assembly 200, the gap between the energy storage assembly 200 and the inner wall of the first accommodating cavity 101 of the cabinet 10 can ignore the requirement of electrical clearance during arrangement, so that the energy storage assembly 200 and the cabinet 10 are more compact during arrangement, and the overall volume of the energy storage housing 100 and the energy storage assembly 200 is smaller, so that the energy density of the energy storage cabinet is greatly improved.

[0056] In this embodiment, the energy storage assembly 200 is arranged in the second accommodating cavity of the insulating structure 20. The insulating structure 20 can provide good insulation protection and electrical isolation for the energy storage assembly 200, so that the cabinet 10 of the energy storage shell 100 in this embodiment can be set as a metal cabinet with better structural strength as needed, so that the cabinet 10 can have good structural strength, so that the cabinet 10 can play a better protective role.

[0057] According to the energy storage housing 100 of the embodiment of the utility model, by providing a cabinet 10 and an insulating structure 20, the insulating structure 20 is arranged in the first accommodating cavity 101 of the cabinet 10, and the energy storage assembly 200 is arranged in the second accommodating cavity of the insulating structure 20, so that the insulating structure 20 plays a role of stable and reliable insulation separation between the energy storage assembly 200 and the cabinet 10, thereby reducing the gap when the energy storage assembly 200 is installed in the cabinet 10, making the overall structure of the energy storage cabinet 1000 more compact, and the energy density of the energy storage cabinet 1000 is greatly improved.

[0058] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the insulating structure 20 may include: two first insulating plates 21 and two second insulating plates 22, the two first insulating plates 21 are arranged in a first direction in a horizontal plane (eg Figure 5 The two second insulating plates 22 are arranged in an interval manner in the up-down direction (as shown in the left-right direction); Figure 5The two second insulating plates 22 are arranged at intervals in the up-down direction (as shown in the figure), and the two second insulating plates 22 are connected to the two first insulating plates 21 at both ends in the first direction, so as to cooperate to define a second accommodating cavity.

[0059] In this embodiment, two first insulating plates 21 are arranged at intervals in the first direction in the horizontal plane, and two second insulating plates 22 are arranged at intervals in the up-down direction, so that the insulating structure 20 can provide stable and reliable insulation protection for the energy storage component 200 on both sides of the first direction and on both sides of the up-down direction, so that the energy storage component 200 can be stably and reliably insulated and separated from the inner wall of the first accommodating cavity 101 of the cabinet 10 on both sides of the first direction and on both sides of the up-down direction.

[0060] The two second insulating plates 22 of this embodiment are respectively connected to the first insulating plates 21 at both ends of the first direction, so that the two second insulating plates 22 and the two first insulating plates 21 form a second accommodating cavity, which has a simple structure and is easy to assemble, so that the outer peripheral surface of the energy storage component 200 in the first direction and the up and down directions can be reliably and stably insulated and protected.

[0061] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, the first insulating plate 21 is disposed in the second direction (eg Figure 5 A first flange 211 may be provided on both sides of the first insulating plates 21 in the front-to-back direction (as shown), and the first flanges 211 of the two first insulating plates 21 on the same side of the second direction extend toward each other.

[0062] In this embodiment, the first insulating plate 21 is provided with first flanges 211 on both sides of the second direction. Specifically, the first flanges 211 extend along the first direction, so that the first insulating plate 21 can cover the energy storage component 200 on one side of the first direction and on both sides of the second direction, so that the insulating structure 20 can provide better insulation protection for the energy storage component 200.

[0063] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, the second insulating plate 22 may be provided with second flanges 221 on both sides of the second direction, the second flanges 221 on the same side of the two second insulating plates 22 in the second direction extend toward each other, and each second flange 221 is connected to the two first flanges 211 at both ends in the first direction.

[0064] The second insulating plate 22 is provided with second flanges 221 on both sides of the second direction, and the second flanges 221 can extend in the up-down direction, so that the second insulating plate 22 can cover the energy storage component 200 on one side of the energy storage component 200 in the up-down direction and on both sides of the second direction, thereby making the insulating structure 20 have a better insulation protection effect on the energy storage component 200.

[0065] In this embodiment, the two first insulating plates 21 and the two second insulating plates 22 are connected by the first flange 211 and the second flange 221, so that the two first insulating plates 21 and the two second insulating plates 22 can form a unified whole, so that the overall structure of the insulating structure 20 is relatively stable, and the insulating structure 20 can enclose a stable second accommodating cavity, so that the insulating structure 20 can play a role in stable insulation protection for the energy storage component 200. In this embodiment, the first insulating plate 21 and the second insulating plate 22 in the insulating structure 20 are connected by the first flange 211 and the second flange 221, which has a simple structure and is easy to form.

[0066] In some embodiments of the present invention, reference Figure 3-Figure 6 As shown, the insulating structure 20 may have a heat dissipation inlet 201 and a heat dissipation outlet 202, and the energy storage component 200 is suitable for having a heat dissipation channel 2201 connected to the heat dissipation inlet 201 and the heat dissipation outlet 202; the energy storage shell 100 also includes an airflow driving member 60, and the airflow driving member 60 is suitable for driving the gas from the heat dissipation inlet 201 to the heat dissipation outlet 202 through the heat dissipation channel 2201.

[0067] It can be understood that when the energy storage shell 100 is in operation, the energy storage component 200 generates heat. In this embodiment, a heat dissipation inlet 201 and a heat dissipation outlet 202 are provided on the insulation structure 20, and the heat dissipation inlet 201 and the heat dissipation outlet 202 are both connected to the heat dissipation channel 2201 in the energy storage component 200. When the energy storage shell 100 is in operation, the airflow driving member 60 is in operation, and the heat generated by the energy storage component 200 is transferred to the air in the heat dissipation channel 2201. The air in the heat dissipation channel 2201 flows along the heat dissipation channel 2201 and flows out from the heat dissipation outlet 202 under the driving action of the airflow driving member 60. The air outside the insulation structure 20 enters the heat dissipation channel 2201 from the heat dissipation inlet 201. Therefore, as the gas flows in and out of the heat dissipation channel 2201, the heat generated by the energy storage component 200 is continuously dissipated.

[0068] In this embodiment, the airflow driving member 60 is provided to drive the gas to flow from the heat dissipation inlet 201 to the heat dissipation outlet 202 through the heat dissipation channel 2201, so that the energy storage component 200 can obtain a good heat dissipation effect during operation. The heat dissipation inlet 201 and the heat dissipation outlet 202 are provided on the insulation structure 20 to facilitate the inflow and outflow of gas, thereby meeting the heat dissipation needs of the energy storage component 200 during operation. The structure is simple and easy to use. Optionally, the airflow driving member 60 is a fan.

[0069] In one example of the present invention, Figure 5 and Figure 6As shown, the insulating structure 20 may include: two first insulating plates 21 and two second insulating plates 22, the two first insulating plates 21 are arranged at intervals in the first direction in the horizontal plane, and the two second insulating plates 22 are arranged at intervals in the up and down directions, and in the second direction, one end of the two first insulating plates 21 and one end of the two second insulating plates 22 enclose a heat dissipation inlet 201, and the other end of the two first insulating plates 21 and the other end of the two second insulating plates 22 enclose a heat dissipation outlet 202.

[0070] In this embodiment, the two first insulating plates 21 and the two second insulating plates 22 enclose a heat dissipation inlet 201 at one end in the second direction. Specifically, on the same side of the energy storage assembly 200 in the second direction, the two first flanges 211 of the first insulating plate 21 can be connected and fixed with the two second flanges 221 of the second insulating plate 22 to form the heat dissipation inlet 201. The other end of the two first insulating plates 21 and the other end of the two second insulating plates 22 in the second direction enclose a heat dissipation outlet 202. Specifically, on the same side of the energy storage assembly 200 in the second direction, the two first flanges 211 of the first insulating plate 21 can be connected and fixed with the two second flanges 221 of the second insulating plate 22 to form the heat dissipation outlet 202.

[0071] In this embodiment, the first insulating plate 21 and the second insulating plate 22 are respectively connected and enclosed at both ends of the second direction to form a heat dissipation inlet 201 and a heat dissipation outlet 202. The structure is simple, and the shaping arrangement of the heat dissipation inlet 201 and the heat dissipation outlet 202 is convenient, so that the airflow can stably flow through the energy storage component 200 in the process of flowing from the heat dissipation inlet 201 to the heat dissipation outlet 202, so that the energy storage component 200 can obtain a good and stable heat dissipation effect.

[0072] In one embodiment of the present invention, Figure 5 As shown, the insulation structure 20 may be provided with a reinforcing beam 231 at the heat dissipation outlet 202 . The reinforcing beam 231 extends along the second direction and is arranged in multiple intervals in the up and down directions. Both ends of the reinforcing beam 231 are respectively connected to the two side edges of the heat dissipation outlet 202 in the first direction.

[0073] In this way, the structural strength of the insulation structure 20 at the heat dissipation outlet 202 can be improved, so that when the airflow flows out of the heat dissipation outlet 202 along the heat dissipation channel 2201 under the suction action of the airflow driving member 60, the insulation structure 20 can maintain a relatively stable structural state, so that the insulation structure 20 can stably play the role of insulation separation, so that the energy storage component 200 can obtain stable and good insulation protection. For example, the number of reinforcement beams 231 can be two, three, four, etc., and the number and arrangement interval of the reinforcement beams 231 can be reasonably set according to needs.

[0074] In one example of the present invention, Figure 5 As shown, the insulating structure 20 may further include a connecting insulating plate 23, the connecting insulating plate 23 is connected to the first flange 211 and the second flange 221, and a heat dissipation outlet 202 is provided on the connecting insulating plate 23. In this way, the structural strength of the insulating structure 20 at the heat dissipation outlet 202 can be further improved, so that the two first insulating plates 21 and the two second insulating plates 22 can be more stably and reliably connected as one through the connecting insulating plate 23, so that the insulating structure 20 can more stably and reliably play the role of insulating protection for the energy storage component 200.

[0075] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the cabinet 10 may be provided with an air inlet 111 and an air outlet 112 , the heat dissipation inlet 201 is communicated with the air inlet 111 , and the heat dissipation outlet 202 is communicated with the air outlet 112 .

[0076] In this embodiment, an air inlet 111 and an air outlet 112 are arranged on the cabinet 10, and the air inlet 111 is connected to the heat dissipation inlet 201, and the air outlet 112 is connected to the heat dissipation outlet 202. The structure is simple, so that when the energy storage shell 100 is in operation, the heat generated by the energy storage assembly 200 can be discharged out of the cabinet 10 in time, so that the energy storage shell 100 can operate stably.

[0077] In one embodiment of the present invention, reference Figure 4 and Figure 5 As shown, in the projection plane perpendicular to the second direction, the projection of the air outlet 112 can be located at the center of the projection of the energy storage assembly 200. In this way, when the gas flows from the multiple heat dissipation channels to the air outlet 112, the airflow can flow more evenly between the multiple battery modules 220 arranged at intervals in the vertical direction, thereby making the temperature uniformity of the energy storage assembly 200 better and making the operation of the energy storage assembly 200 more stable. Figure 7 and Figure 8 As shown, Figure 7 is a schematic diagram of the temperature distribution of the energy storage cabinet 1000 during the simulation process, Figure 8 Schematic diagram of temperature difference distribution. It can be seen from the figure that within the arrangement range of the energy storage assembly 200, the temperature and the temperature difference are relatively uniform. In this embodiment, the energy storage assembly 200 in the energy storage housing 100 can obtain relatively uniform and good heat dissipation. The heat is dissipated by the airflow driving member 60, so that the temperature uniformity in the energy storage housing 100 is better, so that the energy storage cabinet 1000 can operate stably.

[0078] In one embodiment of the present invention, Figure 3As shown, the shapes of the air inlet 111 and the air outlet 112 can both be rectangular. This makes the air inlet 111 and the air outlet 112 easy to process, simple in structure, and convenient for the inflow and outflow of gas, so that the air inlet 111 and the air outlet 112 can have larger air inlet and outlet areas. Of course, the shapes of the air inlet 111 and the air outlet 112 can also be set to other shapes as needed, for example, the air inlet 111 and the air outlet 112 can be set to rounded rectangles, ellipses, waist shapes, etc.

[0079] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the energy storage housing 100 may further include a deflector 30 , which is sealed between the heat dissipation outlet 202 and the air outlet 112 , and the deflector 30 cooperates with the insulation structure 20 and the cabinet 10 to form an air outlet channel.

[0080] In this embodiment, the air deflector 30 is provided, so that the airflow in the heat dissipation channel 2201 can stably flow along the air outlet channel to the air outlet 112 and be discharged to the outside of the cabinet 10, thereby preventing heat from escaping into the first accommodating cavity 101 of the cabinet 10, so that the energy storage housing 100 can have a good heat dissipation effect, and the air deflector 30 has a simple structure and is easy to use. Optionally, the air deflector 30 is an insulating member, which can play a good insulating and separating role for the energy storage assembly 200 and the cabinet 10, so that the energy storage housing 100 can operate more stably and safely.

[0081] In some examples of the present invention, Figure 3 and Figure 4 As shown, a sealing member 70 may be provided between the air guide cover 30 and the insulating structure 20 , and the air guide cover 30 and the insulating structure 20 are sealedly connected via the sealing member 70 .

[0082] In this embodiment, a seal 70 is provided between the air guide cover 30 and the insulating structure 20, which can play a good sealing role on the connection and matching surface between the air guide cover 30 and the insulating structure 20, thereby effectively preventing the high-temperature gas from flowing from the gap at the connection and matching surface between the air guide cover 30 and the insulating structure 20 to the first accommodating cavity 101, so that the energy storage housing 100 can perform a more stable and reliable heat dissipation operation, and the energy storage assembly 200 in the energy storage housing 100 has a better heat dissipation effect. Optionally, the seal 70 can be a sealing strip.

[0083] In an example of the present invention, the sealing member 70 may extend in a ring shape along the circumference of the heat dissipation outlet 202 .

[0084] In this embodiment, the sealing member 70 is arranged to extend in a ring shape along the periphery of the heat dissipation outlet 202 , which can meet the sealing requirements of the air guide cover 30 and the insulation structure 20 and allow the airflow to flow stably in the first accommodating cavity 101 and the air outlet channel.

[0085] In some examples of the present invention, reference Figure 4 As shown, in the direction from the heat dissipation outlet 202 to the air outlet 112 , the cross-sectional size of the air guide cover 30 may first be gradually reduced and then remain unchanged.

[0086] In this embodiment, the cross-sectional size of the air deflector 30 is set to gradually decrease in the direction from the heat dissipation outlet 202 to the air outlet 112, so that the inner wall surface of the air deflector 30 can play a good role in gathering and guiding the flow, so that the airflow in the heat dissipation channels 2201 arranged in the vertical direction of the energy storage component 200 can stably flow to the air outlet 112, and to a certain extent, the airflow can flow out of the cabinet 10 more quickly, so that the energy storage cabinet 1000 has better heat dissipation efficiency. The cross-sectional size of the air deflector 30 remains unchanged after being reduced to a certain size, which can facilitate the air deflector 30 to form a good connection and fixing surface with the inner wall surface of the cabinet 10 with the air outlet 112, so that the air deflector 30 and the cabinet 10 can be stably and conveniently connected and installed.

[0087] In some examples of the present invention, reference Figure 4 As shown, the outer surface of the air guide cover 30 , the outer surface of the insulation structure 20 and the inner wall of the first accommodating cavity 101 can cooperate to define an air inlet channel, and the air inlet channel is connected to the air inlet 111 and the heat dissipation inlet 201 .

[0088] It can be understood that the heat generated by the energy storage component 200 during operation may flow out from the heat dissipation inlet 201 of the insulating structure 20 into the first accommodating cavity 101. Under the influence of the external environment, the energy storage shell 100 and the cabinet 10 will also transfer heat to the first accommodating cavity 101. In this embodiment, the outer surface of the air guide cover 30 cooperates with the outer surface of the insulating structure 20 and the inner wall of the first accommodating cavity 101 to define an air inlet channel. The airflow can flow from the gap between the outer surface of the insulating structure 20 in the upper and lower directions and the inner wall of the first accommodating cavity 101, the airflow can also flow from the gap between the outer surface of the insulating structure 20 in the first direction and the inner wall of the first accommodating cavity 101, and the airflow can also flow in the gap between the side of the insulating structure 20 with the heat dissipation inlet 201 in the second direction and the inner wall of the first accommodating cavity 101.

[0089] When the energy storage shell 100 is in operation, gas flows into the first accommodating chamber 101 from the air inlet 111, and the gas can flow along the air inlet channel between the inner wall of the first accommodating chamber 101 and the outer surface of the insulating structure 20 and the outer surface of the air guide cover 30, thereby achieving a good ventilation and heat dissipation effect on the energy storage assembly 200 in the energy storage shell 100.

[0090] In this embodiment, the outer surface of the air guide cover 30 cooperates with the outer surface of the insulating structure 20 and the inner wall of the first accommodating cavity 101 to define an air inlet channel, and the structure is simple. The airflow entering the first accommodating cavity 101 can flow around the outer periphery and the upper and lower sides of the insulating structure 20, so that the first accommodating cavity 101 can be well ventilated and heat-dissipated, thereby achieving a better heat dissipation effect of the energy storage assembly 200 in the energy storage shell 100.

[0091] In one embodiment of the present invention, Figure 3 and 4 As shown, the cabinet 10 is provided with an air inlet 111 and an air outlet 112 on one side in the second direction, and the energy storage shell 100 may further include a first wind cover, which is provided at the position of the air inlet 111 and / or the air outlet 112.

[0092] It can be understood that the air outlet 112 in this embodiment is connected to the heat dissipation channel 2201 of the energy storage component 200 through the heat dissipation outlet 202 of the insulating structure 20, the heat dissipation channel 2201 extends along the second direction, and the heat dissipation inlet 201 of the insulating structure 20 is located at the other end of the heat dissipation channel 2201 in the second direction. In this embodiment, the air inlet 111 and the air outlet 112 are arranged on the same side of the cabinet 10 in the second direction, so that when the energy storage shell 100 is in operation, the airflow enters from the air inlet 111 and flows in the first accommodating cavity 101 along the second direction, and flows to the side of the energy storage component 200 away from the air guide cover 30 in the second direction, and the airflow then flows from the heat dissipation inlet 201 of the insulating structure 20 into the heat dissipation channel 2201, thereby allowing the energy storage component 200 to perform air cooling and heat dissipation.

[0093] In this embodiment, the air inlet 111 and the air outlet 112 are arranged on the same side of the cabinet 10 in the second direction, so that the airflow can flow fully in the first accommodating cavity 101 along the air inlet channel after entering the first accommodating cavity 101, so that the energy storage component 200 in the energy storage shell 100 can obtain a better heat dissipation effect.

[0094] In the present embodiment, a first wind hood is provided, and the first wind hood is provided at the air inlet 111 and / or the air outlet 112. The first wind hood can be provided at the air inlet 111, and the first wind hood can also be provided at the air outlet 112. The first wind hood can also be provided at both the air inlet 111 and the air outlet 112. In the present embodiment, the first wind hood is provided at the air inlet 111 and / or the air outlet 112, which can facilitate the airflow to flow into or out of the energy storage shell 100 at the air inlet 111 and / or the air outlet 112, and can provide good protection for the air inlet 111 and / or the air outlet 112.

[0095] In one embodiment of the present invention, Figure 3 and 4As shown, there may be multiple first air hoods, at least one of the multiple first air hoods is formed as an air inlet hood 40, at least another one of the multiple first air hoods is formed as an air outlet hood 50, the air inlet hood 40 is arranged at the air inlet 111, and the air outlet hood 50 is arranged at the air outlet 112, the air inlet hood 40 and the cabinet 10 can cooperate to define an air inlet channel, and the air outlet hood 50 can cooperate with the cabinet 10 to define an exhaust channel.

[0096] In this embodiment, the first air hood is provided with a plurality of and at least two are formed as air inlet hoods 40 and air outlet hoods 50, respectively, which facilitates the unified processing and production of the air inlet hoods 40 and the air outlet hoods 50. The air inlet hood 40 cooperates with the cabinet 10 to form an air inlet channel, and the air outlet hood 50 cooperates with the cabinet 10 to define an exhaust channel. The structure is simple, which facilitates the flow of airflow, and can make the cabinet 10 better meet the protection requirements of the energy storage assembly 200. Optionally, the arrangement of the air inlet hood 40 and the air outlet hood 50 can meet the IP55 protection level of the energy storage cabinet 1000.

[0097] In a specific embodiment of the present invention, Figure 4 As shown, the opening of the first wind shield can be arranged downward.

[0098] In this embodiment, the opening orientation of the first wind shield can provide good waterproofing for the air inlet 111 and / or the air outlet 112, so that the energy storage housing 100 can stably and well intake and / or exhaust air, making the energy storage housing 100 operate more stably.

[0099] For example, when two first wind hoods are provided and they are respectively formed as an air inlet hood 40 and an air outlet hood 50, the inlet of the air inlet hood 40 can be arranged downward, and the outlet of the air outlet hood 50 can be arranged downward, so that rainwater and the like can be well prevented from falling into the air inlet channel and / or the exhaust channel, so that the energy storage shell 100 can stably and well intake and exhaust air, and the operation of the energy storage shell 100 is more stable. In addition, since the air inlet 111 and the air outlet 112 are arranged on the same side of the cabinet 10 in the second direction in this embodiment, the air inlet 111 and the air outlet 112 are respectively provided with the first wind hoods in this embodiment, and the first wind hoods are opened downward, the air inlet hood or the exhaust hood can play a role of separation when the gas flows in or out, so that the inflow and outflow of the gas are more stable and do not interfere with each other, and the influence of the outflowing airflow with a higher temperature on the inflowing airflow can be avoided to a certain extent, so that the energy storage component 200 can obtain a better heat dissipation effect.

[0100] Exemplarily, when the air inlet 111 is arranged on the upper side of the air outlet 112, the air outlet cover 50 can separate the exhausted gas from the incoming air at the air inlet cover 40, thereby reducing the probability of the exhausted gas entering the first accommodating chamber 101 from the air inlet 111, so that the incoming air can have a good heat dissipation effect on the energy storage shell 100. When the air inlet 111 is arranged on the lower side of the air outlet 112, the air inlet cover 40 can play the same role, so that during the operation of the energy storage shell 100, the energy storage shell 100 can obtain a stable and good ventilation and heat dissipation effect, so that the energy storage shell 100 can operate more stably.

[0101] In one embodiment of the present invention, reference Figure 4 As shown, the air inlet 111 may include: a first air inlet and a second air inlet, and the first air inlet and the second air inlet are respectively arranged on both sides of the air outlet 112 in the up and down directions.

[0102] In the present embodiment, a first air inlet and a second air inlet are provided, and the first air inlet and the second air inlet are respectively arranged on both sides of the air outlet 112 in the up-down direction.

The airflow in the first accommodating chamber 101 flows more evenly in the up-down direction, so that a more even heat dissipation and cooling effect can be obtained in the first accommodating chamber 101 of the energy storage shell 100, and a plurality of battery modules 220 arranged up and down in the energy storage assembly 200 can obtain even and good ventilation and heat dissipation, so that the operation of the energy storage assembly 200 is more stable, and the energy storage shell 100 can operate more stably and well.
