[0002] As an energy storage device, the energy storage converter has bidirectional power capability and flexible adjustment characteristics. It can effectively mitigate the negative impact of the fluctuation and intermittency of renewable energy power generation on the power grid and improve the grid's ability to accommodate distributed new energy sources, thus having broad application prospects. Among them, the power conversion system (PCS) is one of the key components of the energy storage converter, which can convert DC energy stored in different types of batteries into AC power that meets the corresponding standards.

[0003] Currently, power supply, output, and distribution to the energy storage module are controlled by a power distribution module connected to it, in order to protect and segment the circuit of the energy storage converter. The power distribution module includes an AC circuit breaker, with a handle on one side. Turning the handle opens or closes the AC circuit of the energy storage module, providing overcurrent protection. However, turning the handle requires considerable force, making manual operation difficult. Furthermore, the existing AC circuit breakers are located low within the energy storage converter and are subject to other structural obstructions, further increasing the difficulty of manual operation and maintenance.

[0004] In addition, the current structure and layout of the power distribution module is not reasonable enough, which makes the power distribution module occupy a large space, resulting in an increase in the size of the energy storage converter, which is not conducive to the miniaturization of the equipment.

[0024] Please see Figures 1 to 6 The modular energy storage converter 100 of this utility model embodiment includes: The rack 20 includes an upper mounting space and a lower mounting space space that are spaced apart in the vertical direction; Energy storage modules installed in the upper installation space; and The power distribution module 10, located in the lower installation space, includes an AC side component 11 and a DC side component 12, wherein: The AC side component 11 includes a plurality of AC circuit breakers 111 connected to the AC terminal of the energy storage module. In the vertical direction, the AC circuit breakers 111 are located in the middle of the lower installation space. An operation port 21 is provided in front of the AC circuit breaker 111 and spaced apart from it. There is an operation space 22 between the operation port 21 and the AC circuit breaker 111. The DC side assembly 12 includes multiple DC fuses 121 connected to the DC end of the energy storage module and multiple DC manual maintenance switches 122 connected to the multiple DC fuses 121 respectively. The multiple DC fuses 121 are arranged on the racks 20 on both sides of the operating space 22, and the multiple DC manual maintenance switches 122 are arranged below the operating port 21.

[0025] In the containerized energy storage converter 100 of this embodiment, for the AC side component 11, the AC circuit breaker 111 is located in the middle of the lower installation space in the vertical direction. The position of the AC circuit breaker 111 in the converter 100 is higher than that of the prior art, making it easier for users to operate manually. Moreover, an operation port 21 is provided in front of the AC circuit breaker 111 at a distance from it, and there is an operation space 22 between the operation port 21 and the AC circuit breaker 111, which provides sufficient space for users to manually operate the AC circuit breaker 111, further improving operability. For the DC side component 12, multiple DC fuses 121 are set on the racks 20 on both sides of the operation space 22, and multiple DC manual maintenance switches 122 are set below the operation port 21. They do not obstruct the AC circuit breaker 111, making it convenient to operate the AC circuit breaker 111 manually. They also make full use of the space of the containerized energy storage converter 100, which is conducive to the miniaturization of the equipment.

[0026] In this embodiment, the overall structure of the containerized energy storage converter 100 is similar to that of a shipping container. The frame 20 can be a roughly cubic or rectangular stainless steel frame structure. The upper and lower installation spaces are the internal spaces of the frame 20, which are formed by the partitions / mounting plates / frames of the frame 20 in the middle of the frame 20 and distributed along the vertical direction of the frame 20 (which can be understood as the height direction or the Y-axis direction in the attached figure).

[0027] The upper mounting space is located relatively above the rack 20, meaning the energy storage module is located on the upper side of the rack 20. The lower mounting space is located relatively below the rack 20, meaning the power distribution module 10 is located on the lower side of the rack 20. The power distribution module 10 is used to control the power supply, output, and distribution of the energy storage module, in order to protect and segment the circuit of the modular energy storage converter 100. For example, when a certain energy storage device in the energy storage module is damaged or needs to be disconnected from power, the power distribution module 10 can disconnect the power supply and output of the corresponding energy storage device and switch to other energy storage devices that can be used / output normally.

[0028] Multiple glands can be installed between the upper and lower installation spaces, with the glands located on the base plate of the rack 20 where the upper installation space is located. The glands are arranged in groups, with each group corresponding to each energy storage device of the energy storage module. The energy storage module and the power distribution module 10 are electrically connected via multiple sets of connecting cables. Each set of connecting cables passes through its corresponding set of glands and then into the lower installation space. The glands can fix and restrict the connecting cables between the energy storage devices and the power distribution module 10, ensuring that the connecting cables are arranged in an orderly manner, facilitating wiring and disconnection.

[0029] It is understood that the multiple sets of connecting cables include AC side cables and DC side cables. The AC side cables connect the AC end of the energy storage module to the AC side component 11, and the DC side cables connect the DC end of the energy storage module to the DC side component 12.

[0030] In this embodiment, the AC circuit breaker 111 is used to disconnect or close the AC side circuit of the energy storage module to achieve overcurrent protection against AC current. The AC circuit breaker 111 is installed in the middle of the lower installation space, at a certain height from the bottom of the rack 20, that is, the AC circuit breaker 111 is not installed at the bottom of the rack 20. In this way, maintenance and operation can be conveniently carried out through the operation port 21 and the operation space 22, and the distance between the AC circuit breaker 111 and the energy storage module can be shortened, thereby saving electrical connecting parts such as copper busbars between the two.

[0031] In this embodiment, the DC fuse 121 (i.e., DC fuse wire) is used to provide overcurrent protection against DC current. Multiple DC fuses 121 are evenly spaced along the inner and outer directions of the frame 20 on both sides of the operating space 22 and the AC circuit breaker 111. In this way, the DC side connection cable of the energy storage module can be directly and vertically connected to the electrical connector (i.e., the first DC copper busbar 123 hereinafter) in the DC side assembly 12, which is convenient for wiring, ensures the wiring space of the DC end of the energy storage module, and does not obstruct the AC circuit breaker 111 in the middle.

[0032] In this embodiment, the DC manual service disconnect (MSD) switch 122 is used to disconnect or close the DC side circuit of the module. The operation port 21 is located on the front side of the rack 20. The DC manual service disconnect switch 122 is positioned below the operation port 21, that is, the DC manual service disconnect switch 122 is also located on the front side of the rack 20. This facilitates user operation and does not obstruct the operation port 21, making full use of the lower installation space.

[0033] In this embodiment, the operating port 21 is an opening formed by the structure containing the DC manual maintenance switch 122 and the frame 20. This opening is located on the side of the frame 20 and communicates with the space where the AC circuit breaker 111 is located, thus allowing access to the AC circuit breaker 111 through the operating port 21. The operating port 21 can also be understood as the opening through which a user's hand passes when reaching into the lower installation space to operate the AC circuit breaker 111. All components of the AC-side assembly 11 and the DC-side assembly 12 can be accessed through the operating port 21, facilitating operation, maintenance, installation, and disassembly of the AC-side assembly 11 and the DC-side assembly 12.

[0034] In this embodiment, the operating space 22 is a space formed by a certain distance between the AC circuit breaker 111 and the DC manual maintenance switch 122 located in front of it. This operating space 22 has a certain volume, with a height at least equal to the distance between the top and bottom of the AC circuit breaker 111, a length equal to the distance between the DC fuses 121 on both sides, and a width equal to the distance between the AC circuit breaker 111 and the DC manual maintenance switch 122. This ensures that all components of the AC-side assembly 11 and the DC-side assembly 12 can be accessed through the operating space 22. The operating space 22 can also be understood as the space where the user's hand can move to the maximum extent when reaching through the operating port 21 to operate the AC circuit breaker 111.

[0035] The left and right corners on the front side of the operating space 22 can be regarded as the outer corners of the operating space 22, and the left and right corners on the rear side can be regarded as the rear corners of the operating space 22. The space near the energy storage module is the top space, and the space near the bottom of the rack 20 is the bottom space.

[0036] The rack 20 is equipped with removable cover plates around its perimeter. The cover plates can be made of metal, such as stainless steel, and can be detachably installed around the rack 20 by means of screws, rivets, or snap-fits. When installed on the rack 20, the cover plates, together with the partitions or related structures in the rack 20, can form an upper installation space and a lower installation space, and shield the energy storage module and protect the power distribution module 10.

[0037] When it is necessary to install, disassemble, or repair the energy storage module and / or power distribution module 10, the corresponding cover plate can be removed from the frame 20, which will expose the operation port 21 and the operation space 22, making it convenient for the user to perform the corresponding operations.

[0038] Please see Figures 2 to 6 Furthermore, the AC side component 11 also includes multiple AC copper busbars 112 that connect the AC terminal of the energy storage module to multiple AC circuit breakers 111. The multiple AC copper busbars 112 are evenly arranged on the top of the operating space 22 and extend into the inside of the operating space 22.

[0039] Specifically, one end of the AC copper busbar 112 is located below the AC side cable, and the AC side cable can be connected vertically to the AC copper busbar 112, which facilitates wiring and ensures sufficient wiring space at the output end. Then, the AC copper busbar 112 extends vertically downward and parallel backward to the inside of the operating space 22 to the top of the AC circuit breaker 111, and then extends vertically downward to connect with the AC circuit breaker 111. The AC copper busbar 112 makes full use of the top space of the operating space 22 without obstructing the AC circuit breaker 111.

[0040] The size and dimensions of the multiple AC copper busbars 112 are different, mainly determined by the distance between the AC circuit breaker 111 and the different AC side cables.

[0041] Please see Figures 2 to 6 Furthermore, the DC side assembly 12 also includes a plurality of first DC copper busbars 123 that connect the DC end of the energy storage module to a plurality of DC fuses 121. The plurality of first DC copper busbars 123 are evenly arranged at the two outer corners of the top of the operating space 22 and extend outward to the outside of the operating space 22.

[0042] Specifically, one end of the first DC copper busbar 123 is located below the DC side cable, and the DC side cable can be connected vertically to the first DC copper busbar 123, which facilitates wiring and ensures sufficient wiring space at the output end. Then, the first DC copper busbar 123 extends parallel to the left / right rear to the top of the DC fuse 121, and then extends downward to connect with the top of the DC fuse 121, thus being located at the two outer corners of the top of the operating space 22. The first DC copper busbar 123 is arranged roughly parallel to the bottom of the AC copper busbar 112, making full use of the top space of the operating space 22 and avoiding the front part of the operating space 22 to prevent obstruction of the AC circuit breaker 111.

[0043] The size and dimensions of the multiple first DC copper busbars 123 are different, mainly determined by the distance between the DC fuse 121 and the different DC side cables.

[0044] Please see Figures 2 to 6Furthermore, the DC side assembly 12 also includes a plurality of second DC copper busbars 124 that connect a plurality of DC fuses 121 and a plurality of DC manual maintenance switches 122. The plurality of second DC copper busbars 124 are evenly arranged at the two outer corners of the bottom of the operating space 22 and extend outward from the operating space 22.

[0045] Specifically, one end of the second DC copper busbar 124 is located below the DC fuse 121 and connected to the bottom of the DC fuse 121. It then extends diagonally forward to the rear of the DC manual maintenance switch 122 and is connected to the DC manual maintenance switch 122, thus being located at the two outer corners of the bottom of the operating space 22.

[0046] The second DC copper busbar 124 is arranged roughly parallel to the bottom of the first DC copper busbar 123. The first DC copper busbar 123 and the second DC copper busbar 124 are arranged in two layers at the top and bottom of the operating space 22, which can effectively utilize the space of the operating space 22, thereby compressing the size of the containerized energy storage converter 100, promoting equipment miniaturization, and avoiding obstruction of the front part of the operating space 22, thus avoiding obstruction of the AC circuit breaker 111.

[0047] The size and dimensions of the multiple second DC copper busbars 124 are different, mainly determined by the distance between the DC fuse 121 and the different DC manual maintenance switches 122.

[0048] Please see Figures 2 to 6 Furthermore, an installation beam 23 extending horizontally is provided in front of the AC circuit breaker 111, and multiple DC manual maintenance switches 122 are spaced apart on the installation beam 23.

[0049] In this embodiment, the mounting beam 23 extends along the X-axis direction shown in the attached figure, with both ends respectively disposed on the racks 20 on both sides of the operating space 22. The mounting beam 23 spans the operating space 22, the AC side component 11, and the DC side component 12, located at the front of the rack 20 and facing outwards, forming an operating area with the racks 20 above and at both ends. Multiple DC manual maintenance switches 122 are spaced apart on the mounting beam 23 and face outwards from the rack 20, thereby facilitating operation, maintenance, installation, and disassembly.

[0050] In one embodiment, the mounting beam 23 may be made of stainless steel or other metal materials, which have high strength and ensure the installation stability of the DC manual maintenance switch 122.

[0051] Please see Figures 2 to 6Furthermore, the mounting beam 23 is provided with multiple mounting holes, and multiple DC manual maintenance switches 122 are provided corresponding to the multiple mounting holes with their rear ends exposed on the back of the mounting beam 23. The second DC copper busbar 124 extends from the DC fuse 121 to the back of the mounting beam 23 and is connected to the DC manual maintenance switch 122.

[0052] In this embodiment, the mounting hole extends through the mounting beam 23 along its thickness direction. The DC manual maintenance switch 122 is installed through the mounting hole, resulting in a relatively stable installation. It can be further reinforced with screws or other fasteners. Furthermore, the front end of the DC manual maintenance switch 122 faces the outside of the frame 20 for easy user operation, while the rear end faces the inside of the frame 20 for easy connection to the second DC copper busbar 124 extending to the back of the mounting beam 23. The second DC copper busbar 124 does not protrude from the operating port 21 and will not obstruct the AC circuit breaker 111.

[0053] Please see Figures 2 to 6 Furthermore, a mounting panel 24 extending vertically is provided in the lower mounting space, and the AC circuit breaker 111 is mounted on the side of the mounting panel 24 facing outward from the frame 20 by fasteners.

[0054] Specifically, the mounting panel 24 consists of multiple pieces, which can divide the lower mounting space into two parts. Its main body extends along the XZ axis direction and is perpendicular to the frame 20, thereby allowing for a more stable and secure installation of the AC circuit breaker 111. The rear side of the AC circuit breaker 111 can fit against the side of the mounting panel 24 facing away from the frame 20, improving the stability of the connection with the mounting panel 24 and increasing the heat dissipation area.

[0055] The mounting panel 24 may also be provided with inwardly extending mounting portions around its perimeter, thereby increasing the contact area between the mounting panel 24 and the frame 20 and adjacent mounting panels 24. The aforementioned extended mounting portions can be fixed to the frame 20 and adjacent mounting panels 24 by screws or other fasteners, thereby improving the installation stability of the mounting panel 24.

[0056] In one embodiment, the mounting panel 24 can be fixedly installed in the frame 20 by screws or other fasteners, and the AC circuit breaker 111 can also be directly fixedly installed on the mounting panel 24 by screws or other fasteners, which not only has better installation stability, but also facilitates assembly and disassembly.

[0057] In one embodiment, the mounting panel 24 can be a metal panel made of a material with better strength, such as stainless steel. It not only has better strength to stably install the AC circuit breaker 111, but also conducts heat for the AC circuit breaker 111 and improves the heat dissipation effect.

[0058] Furthermore, the lower installation space is evenly divided into multiple installation areas, each of which is equipped with a power distribution module 10.

[0059] Specifically, multiple mounting panels 24 in the lower mounting space cooperate with the rack 20 to evenly divide the lower mounting space into multiple mounting areas. Each mounting area is equipped with a power distribution module 10, that is, each mounting area is equipped with an AC side component 11 and a DC side component 12, as well as the various components of the AC side component 11 and the DC side component 12.

[0060] Similarly, the upper installation space is also divided into multiple installation areas, which can also be divided by corresponding partitions and racks 20 to install multiple sets of energy storage modules. Dividing the power distribution module 10 and the energy storage module into multiple groups and installing them in corresponding areas allows for independent control and activation, and reduces the overall power load of the containerized energy storage converter 100.

[0061] Taking a rectangular lower installation space as an example, multiple mounting panels 24 and racks 20 can divide the lower installation space into four installation areas.

[0062] Please see Figures 2 to 6 Furthermore, the mounting panel 24 is provided with a ventilation structure 241 corresponding to the AC circuit breaker 111.

[0063] Specifically, the ventilation structure 241 can be a plurality of ventilation holes arranged in an array evenly or a plurality of ventilation holes arranged in a dense array. By setting the ventilation structure 241 on the mounting panel 24 to correspond with the AC circuit breaker 111, the ventilation and heat dissipation effect of the AC circuit breaker 111 can be improved, and the normal operation of the AC circuit breaker 111 can be promoted.
