[0044] The energy storage converter housing 100 according to the first embodiment of the present application will be described below with reference to FIG. 1 to FIG. 7 .

[0045] As shown in Figures 1 to 7, the energy storage converter housing 100 according to the embodiment of the first aspect of the present application includes an energy storage converter installation position 401, a transformer installation position 301, a housing 1 and a partition 2.

[0046] Specifically, the housing 1 includes a housing body 14, which is adapted to define an accommodating chamber 11. The partition 2 includes a first partition 21, which is disposed within the housing body 14 and is configured to divide the accommodating chamber 11 into a plurality of mounting chambers. The plurality of mounting chambers includes a first mounting chamber 111 and a second mounting chamber 112. The energy storage converter mounting position 401 is disposed within the first mounting chamber 111, and the transformer mounting position 301 is disposed within the second mounting chamber 112.

[0047] It should be noted that the installation location (i.e., the energy storage converter installation location 401 and the transformer installation location 301) can be the area where the installation base or installation hole of the energy storage converter housing 100 is located; or, the installation location can also be the installation space of the energy storage converter housing 100. However, the present invention is not limited thereto.

[0048] In addition, the two sides of the partition 2 are separated to form two completely independent spaces. The two sides of the partition 2 can also be partially separated, such as if at least one end of the partition 2 does not abut the inner wall of the accommodating cavity, that is, there is a gap between the partition 2 and the inner wall of the accommodating cavity. Optionally, the transformer module 4 can be completely isolated to prevent mixed flow between the transformer module 4 and surrounding components.

[0049] For example, in the examples of Figures 1 and 2, the shell body 14 is generally rectangular, but is not limited thereto. A first partition 21 is disposed within the accommodating cavity 11, dividing the accommodating cavity 11 into a first mounting cavity 111 and a second mounting cavity 112. The energy storage inverter mounting position 401 is suitable for mounting the energy storage inverter module 4, and the transformer mounting position 301 is suitable for mounting the transformer module 3, wherein the transformer module 3 performs step-up and step-down processing on the AC power output and input of the energy storage inverter module 4; the energy storage inverter module 4 is responsible for the AC / DC bidirectional conversion of each battery device 200.

[0050] Thus, the transformer module 3 and the energy storage converter module 4 are separated by the first partition 21, so that the transformer module 3 and the energy storage converter module 4 are installed in different installation cavities, preventing the transformer module 3 and the energy storage converter module 4 from performing heat exchange and avoiding excessive temperatures of the transformer module 3 and the energy storage converter module 4, thereby improving the operational stability of the transformer module 3 and the energy storage converter module 4 and further ensuring the service life of the energy storage converter housing 100. In addition, the integration of the housing 1 is increased, while making the overall layout of the housing 1 more compact, thereby improving the space utilization of the housing 1.

[0051] Referring to Figure 7, during application, one end of the energy storage converter housing 100 can be connected to the battery device 200 to power the energy storage converter housing 100, and the other end of the energy storage converter housing 100 can be connected to the power grid. This reduces the number of equipment cabinets used, reduces the difficulty of installing the energy storage converter housing 100, and allows the energy storage converter housing 100 to be flexibly installed according to the site, thereby improving the installation efficiency of the energy storage converter housing 100. Furthermore, the overall layout of the housing 1 is made more compact, improving the space utilization of the energy storage converter housing 100. Furthermore, the energy storage converter module 4 and the transformer module 3 are independent of each other, meaning that when a module fails, it can be replaced and repaired separately, reducing the difficulty of maintenance and the maintenance cost of the energy storage converter housing 100.

[0052] According to the energy storage converter housing 100 of the embodiment of the present application, by arranging the first partition plate 21 in the accommodating cavity 11, the energy storage converter mounting position 401 and the transformer mounting position 301 are spaced apart in the accommodating cavity 11. In this way, the transformer module 3 and the energy storage converter module 4 can be separated, so that the transformer module 3 and the energy storage converter module 4 are installed in different mounting cavities, thereby preventing the transformer module 3 and the energy storage converter module 4 from performing heat exchange and avoiding the transformer module 3 and the energy storage converter module 4 from overheating, thereby improving the operational stability of the transformer module 3 and the energy storage converter module 4 and further ensuring the service life of the energy storage converter housing 100.

[0053] According to some embodiments of the present application, the housing 1 has a first mounting cavity 111 and a second mounting cavity 112 arranged along a first direction. The energy storage converter module 4 and the transformer module 3 both serve as primary heat sources. By placing the energy storage converter module 4 and the transformer module 3 in different mounting cavities, the heat generated by the energy storage converter module 4 and the transformer module 3 are prevented from interfering with each other's operation, thereby improving the operational stability of the energy storage converter module 4 and the transformer module 3.

[0054] The first direction may be any one of a height direction (e.g., the up-down direction in FIG. 1 ), a width direction (e.g., the left-right direction in FIG. 1 ), and a thickness direction (e.g., the front-back direction in FIG. 1 ). Preferably, the first direction is the height direction, thereby placing the heavier transformer module 3 at the bottom of the energy storage and converter housing 100 , thereby increasing the stability and safety of the energy storage and converter housing 100 .

[0055] Optionally, the spacing distance between the energy storage converter module 4 and the transformer module 3 can also be set as needed to make the structure in the accommodating cavity 11 compact, which is not specifically limited here.

[0056] Furthermore, the partition 2 also includes a second partition 22, which is disposed in the first installation cavity 111 and is used to separate the first installation cavity 111 into a third installation cavity 1111 and a fourth installation cavity 1112. The energy storage converter installation position 401 is disposed in the third installation cavity 1111. The energy storage converter housing 100 also includes a power distribution installation position 1001, which is disposed in the fourth installation cavity 1112. The power distribution installation position 1001 is suitable for installing a power distribution module 102, which is used to control the on and off of each module. The second partition 22 separates the first installation cavity 111 into the third installation cavity 1111 and the fourth installation cavity 1112, that is, the energy storage converter module 4 and the power distribution module 102 are installed at intervals, reducing heat exchange between the energy storage converter module 4 and the power distribution module 102, thereby avoiding heat interference that causes operational errors of the energy storage converter module 4 and the power distribution module 102.

[0057] According to some embodiments of the present application, the partition 2 further includes a third partition 23, which is disposed within the fourth mounting cavity 1112 and is used to separate the fourth mounting cavity 1112 into a fifth mounting cavity 11111 and a sixth mounting cavity 11112. The power distribution mounting position 1001 is disposed within the fifth mounting cavity 11111. The energy storage converter housing 100 further includes a communication mounting position 1002, which is disposed within the sixth mounting cavity 11112. The communication mounting position 1002 is suitable for mounting a communication module. The communication module is used to connect the various modules to enable remote maintenance, remote alarming, remote control, remote data collection, and the like. For example, the shell 1 has a first direction, and the fourth installation cavity 1112 is divided into a fifth installation cavity 11111 and a sixth installation cavity 11112 by the third partition plate 23. The fifth installation cavity 11111 and the sixth installation cavity 11112 are arranged along the first direction (for example, the up and down direction in Figure 1), that is, the distribution module 102 and the communication module are installed at intervals to reduce the heat exchange between the distribution module 102 and the communication module, thereby avoiding heat interference and causing errors in the operation of the distribution module 102 and the communication module.

[0058] According to some embodiments of the present application, the housing 1 has a second direction, and the third installation cavity 1111 and the fourth installation cavity 1112 are arranged along the second direction, and the second direction is perpendicular to the first direction. The second direction can be any one of the thickness direction (for example, the front-to-back direction in FIG1 ), the height direction (for example, the up-down direction in FIG1 ), and the width direction (for example, the left-right direction in FIG1 ). Preferably, the second direction is the width direction, whereby the second partition 22 separates the first installation cavity 111 into the third installation cavity 1111 and the fourth installation cavity 1112 arranged along its width direction, that is, the second partition 22 divides the interior of the housing 1 into two parts, the left and right parts, the energy storage converter module 4 is located on the left side of the interior of the housing 1, and the power distribution module 102 is located on the right side of the interior of the housing 1, so as to reduce the heat exchange between the energy storage converter module 4 and the power distribution module 102.

[0059] According to some embodiments of the present application, as shown in Figures 1 and 2, the partition 2 further includes a fourth partition 25, which is disposed within the sixth installation cavity 11112 and is used to separate the sixth installation cavity 11112 into a seventh installation cavity 11113 and an eighth installation cavity 11114. The communication installation position 1002 is disposed within the seventh installation cavity 11113. The energy storage converter housing 100 further includes a control installation position 1003, which is disposed within the eighth installation cavity 11114.

[0060] For example, in the examples of Figures 1 and 2, the fourth partition 25 divides the sixth installation cavity 11112 into a seventh installation cavity 11113 and an eighth installation cavity 11114 arranged in the left-right direction. The eighth installation cavity 11114 is suitable for installing a control module such as the EMS module 104 and the temperature controller 103. The EMS module 104 is used to manage the energy of the energy storage converter housing 100, and the temperature controller 103 is used to collect the temperature of the transformer module 3. In other words, the EMS module 104 can comprehensively control the energy of the energy storage converter housing 100, thereby increasing the safety of the energy storage converter housing 100; the temperature controller 103 timely monitors the temperature of the transformer module 3 to prevent the transformer module 3 from overheating and affecting its operation, thereby ensuring the stability and safety of the transformer module 3. Thus, the communication module is separated from the EMS module 104 and the temperature controller 103, reducing the heat transfer between the communication module, the EMS module 104 and the temperature controller 103, thereby increasing the operational stability and safety of the communication module, the EMS module 104 and the temperature controller 103.

[0061] It should be noted that the control module is not limited to the EMS module 104 and the temperature controller 103 , and may also be a control element with other functions.

[0062] It should be noted that the distance between each partition can be set according to the size of the modules installed in each accommodating cavity, and is not specifically limited here.

[0063] According to some embodiments of the present application, the energy storage converter housing 100 further includes an inverter mounting position 1004, which is disposed in the second mounting cavity 112. Referring to Figure 5, the inverter mounting position 1004 is suitable for mounting the inverter module 5, which includes a first fixing plate 51, an AC bus module 52, a DC bus module 53, and a blocking plate 54. The AC bus module 52, the DC bus module 53, and the blocking plate 54 are all disposed on the first fixing plate 51. The blocking plate 54 is located between the AC bus module 52 and the DC bus module 53, and extends along the thickness direction of the first fixing plate 51. Among them, the AC bus module 52 is mainly responsible for AC power distribution and bus, and the DC bus module 53 is mainly responsible for DC power distribution and bus. The first fixing plate 51 is used to fix the AC bus module 52, the DC bus module 53, and the blocking plate 54, thereby increasing the installation stability of the AC bus module 52, the DC bus module 53, and the blocking plate 54. The blocking plate 54 can effectively separate the AC bus module 52 and the DC bus module 53 to avoid interference between the AC bus module 52 and the DC bus module 53 , thereby increasing the operational stability of the AC bus module 52 and the DC bus module 53 .

[0064] Optionally, the blocking plate 54 may be a plastic partition, which has insulating properties to prevent electric shock from occurring between the AC bus module 52 and the DC bus module 53 .

[0065] Furthermore, the housing 1 includes a door panel 13. One side of the housing body 14 is open, and the door panel 13 is disposed on the open side of the housing body 14. The inverter mounting position 1004 is disposed between the transformer mounting position 301 and the door panel 13. This arrangement effectively utilizes the space between the transformer module 3 and the door panel 13, improving space utilization and making the structure more compact.

[0066] According to some embodiments of the present application, referring to FIG2 , the partition 2 includes a heat insulation device 24 for preventing heat transfer between the mounting cavities. For example, the first partition 21 includes a heat insulation device 24. Since the energy storage converter module 4 is the primary heat source, the heat insulation device 24 reduces heat transfer between the energy storage converter module 4 and the transformer module 3 on both sides of the first partition 21, further ensuring the operational stability of the energy storage converter module 4 and the transformer module 3.

[0067] Similarly, the second partition 22 has a heat insulation device 24, which is used to prevent heat from being transferred between the third installation cavity 1111 and the fourth installation cavity 1112. Since the energy storage converter module 4 is the main heat source, the use of the heat insulation device 24 reduces the heat transfer between the power distribution module 102 and the energy storage converter module 4 on both sides of the second partition 22, further ensuring the operational stability of the power distribution module 102 and the energy storage converter module 4.

[0068] Among them, at least one partition 2 is provided with a heat insulation device 24, and at least one side surface of the partition 2 provided with the heat insulation device 24 is provided with a heat insulation device 24, which is not specifically limited here.

[0069] In some optional embodiments, the thermal insulation device 24 is, but is not limited to, thermal insulation cotton. Thermal insulation cotton has many advantages, including being flame retardant, non-toxic, corrosion-resistant, having a low bulk density, low thermal conductivity, strong chemical stability, low moisture absorption, and good hydrophobicity. Using thermal insulation cotton as the thermal insulation device 24 not only provides excellent thermal insulation but also facilitates lightweight design.

[0070] According to some embodiments of the present application, referring to Figures 1-4, an air inlet 16 and an air outlet 17 are formed on the housing 1. The air inlet 16 includes a first air inlet 161, and the air outlet 17 includes a first air outlet 171. The first air inlet 161 and the first air outlet 171 are in communication with the third installation cavity 1111. With this arrangement, outside air can flow into the third installation cavity 1111 through the first air inlet 161, exchange heat with the energy storage converter module 4, and then be discharged to the outside through the first air outlet 171. This achieves heat dissipation of the energy storage converter module 4, thereby controlling the temperature of the energy storage converter module 4.

[0071] According to some embodiments of the present application, referring to Figures 1-4 , the air inlet 16 includes a second air inlet 162, and the air outlet 17 includes a second air outlet 172. The second air inlet 162 and the second air outlet 172 are in communication with the fourth mounting cavity 1112. With this arrangement, external air can be discharged to the outside world through the second air outlet 172. This achieves heat dissipation for the power distribution module 102 and the inverter module 5, thereby controlling the temperature of the power distribution module 102 and the inverter module 5.

[0072] According to some embodiments of the present application, as shown in Figures 1-4 , the air inlet 16 further includes a third air inlet 163, and the air outlet 17 further includes a third air outlet 173. The third air inlet 163 and the third air outlet 173 are in communication with the second installation cavity 112. External air can flow into the second installation cavity 112 through the third air inlet 163, exchange heat with the inverter module 5, and then, driven by the fan 31, flow toward the transformer module 3 and exchange heat there. The heat-exchanged air is then discharged to the outside through the third air outlet 173. This dissipates heat from the transformer module 3, thereby controlling the temperature of the transformer module 3.

[0073] According to some embodiments of the present application, one side of the housing body 14 is open, and the housing 1 further includes a door panel 13, which is disposed on the open side of the housing body 14. An air inlet 16 is formed on the door panel 13, and the air inlet 16 and the air outlet 17 are in communication with the accommodating chamber 11. The second mounting chamber 112 is suitable for accommodating a fan 31, which is located on one side of the transformer mounting position 301 adjacent to the air outlet 17. The air inlet 16 is formed on one side of the housing 1 in the second direction, and the air outlet 17 is formed on the other side of the housing 1 in the second direction. The air outlet 17 and the air inlet 16 are in communication, so that air enters the accommodating chamber 11 through the air inlet 16, and the hot air in the accommodating chamber 11 is discharged through the air outlet 17 to dissipate the heat generated in the accommodating chamber 11, thereby dissipating heat from the AC / DC bus module, the transformer module 3, the energy storage converter module 4, the control module, and the fire protection module 6 in the accommodating chamber 11, thereby ensuring a stable temperature of the energy storage converter housing 100. When the fan 31 is running, negative pressure is generated in the accommodating chamber 11, which increases the air entering the accommodating chamber 11 from the air inlet 16, and the air flows in the accommodating chamber 11 to achieve heat exchange with each module. The hot air is then discharged from the air outlet 17, thereby forming air flow in the accommodating chamber 11 to improve the heat dissipation efficiency of the energy storage converter housing 100.

[0074] Furthermore, referring to Figures 1 and 2, an air inlet 16 is formed on the housing 1, and the air inlet 16 includes a first air inlet 161 and a second air inlet 162. The energy storage converter housing 100 also includes a fire protection module 6, which is arranged on the side of the door panel 13 facing the housing body 14, and the fire protection module 6 is located between the first air inlet 161 and the second air inlet 162. The energy storage converter module 4 and the power distribution module 102 in the energy storage converter housing 100 generate a large amount of heat. The fire protection module 6 is arranged at the first air inlet 161 and the second air inlet 162, which facilitates the fire protection module 6 to simultaneously monitor the temperature in the third installation cavity 1111 and the fourth installation cavity 1112, so as to ensure that the monitoring data of the fire protection module 6 is consistent with the actual data of the energy storage converter housing 100, thereby ensuring that the energy storage converter housing 100 can operate normally.

[0075] According to some embodiments of the present application, referring to FIG3 , the energy storage inverter housing 100 further includes a warning alarm 7 and an audible and visual alarm 8 .
