[0002] With the development of technology, energy storage systems typically supply power to the load through DC and AC power distribution components in the main control distribution box. To meet user needs, the main control distribution box in energy storage systems is becoming smaller and smaller, while including more and more electrical components. However, as the size of the main control distribution box decreases and the number of electrical components increases, the installation space within the main control distribution box also decreases, which increases the difficulty of arranging the DC and AC power distribution components within the main control distribution box, and also increases the difficulty of wiring the DC and AC power distribution components.

[0004] To address the aforementioned problems, in a first aspect, embodiments of this application provide a main control distribution box, including:

[0005] The housing has an installation cavity, and a partition is provided in the installation cavity to divide the installation cavity into a first installation cavity and a second installation cavity;

[0006] The system includes a DC main control component group, an AC power distribution component group, and a power supply assembly. The DC main control component group is installed in the first mounting cavity, the AC power distribution component group is installed in the second mounting cavity, and the power supply assembly is installed in either the first or the second mounting cavity. The power supply assembly and the DC main control component group are electrically connected.

The first incoming line terminal group and the second incoming line terminal group are both located on the same side wall of the enclosure.

[0008] Optionally, the main control distribution box further includes a load terminal group and a terminal group. The load terminal group is electrically connected to the DC main control component group or the AC power distribution component group through the terminal group. When the circuit between the AC power distribution component group and the load terminal group is disconnected, the load terminal group is electrically connected to the DC main control component group through the terminal group.

[0009] Optionally, the load terminal group, the first incoming terminal group, and the second incoming terminal group are all located on the same side wall of the enclosure.

[0010] Optional, including intersecting first and second directions;

[0011] The partition extends along the second direction to divide the mounting cavity into a first mounting cavity and a second mounting cavity arranged along the first direction, wherein the second direction is along the length of the main control distribution box.

[0012] Optionally, the main control distribution box further includes a heat dissipation component, and the heat dissipation component is installed in both the first mounting cavity and the second mounting cavity;

[0013] The first mounting cavity is smaller in size in the first direction than the second mounting cavity in the first direction. The power supply component is installed in the second mounting cavity, and at least one heat dissipation component is installed on the periphery of the power supply component.

[0014] Optionally, the main control distribution box further includes a temperature sensor, which is installed in at least one of the first mounting cavity and the second mounting cavity, and the temperature sensor is electrically connected to the heat dissipation assembly.

[0015] Optionally, the terminal block is a terminal board, and both the DC main control component group and the AC power distribution component group are electrically connected to the terminal board.

[0016] Optionally, the DC main control component group includes multiple DC main control components, and the AC power distribution component group includes multiple AC power distribution components. The multiple DC main control components are electrically connected through terminal blocks, and the multiple AC power distribution components are electrically connected through terminal blocks.

[0017] Optionally, the DC main control component group includes a first circuit breaker and a switching power supply, and the AC power distribution component group includes a second circuit breaker and an AC voltage converter;

[0018] The main control distribution box also includes a circuit switch, which includes a first input terminal, a second input terminal, and an output terminal.

[0019] Secondly, embodiments of this application provide an energy storage system, which includes the main control distribution box described in any embodiment of the first aspect.

[0020] As can be seen from the above embodiments, in this application embodiment, since the enclosure has an installation cavity, and a partition is provided in the installation cavity, the partition divides the installation cavity into a first installation cavity and a second installation cavity. The DC main control component group is installed in the first installation cavity, the AC power distribution component group is installed in the second installation cavity, and the power supply component is installed in either the first or second installation cavity. The power supply component and the DC main control component group are electrically connected. Therefore, the partition can separate the installation cavity of the enclosure into two independent cavities, allowing the DC main control component group and the AC power distribution component group to be installed in different installation cavities and isolated by the partition. Furthermore, since the first incoming terminal group and the second incoming terminal group are electrically connected, the first incoming terminal group is electrically connected to the power supply component, and the second incoming terminal group is electrically connected to the AC power distribution component group. Both the first incoming terminal group and the second incoming terminal group are located on the same side wall of the enclosure. Therefore, the first incoming terminal group and the second incoming terminal group can be routed through the same side wall of the enclosure, which facilitates the inspection and maintenance of the wiring of the first incoming terminal group and the second incoming terminal group, and makes it convenient for users to connect wires. In summary, the main control distribution box provided in this application embodiment not only allows the DC main control component group and the AC power distribution component group to be installed in different mounting cavities, thus enabling the DC main control component group and the AC power distribution component group to be set up in separate zones, saving the internal space utilization of the main control distribution box and reducing the difficulty of arranging the main control component group and the AC power distribution component group in the main control distribution box, but also allows the first incoming terminal group and the second incoming terminal group to be routed through the same side wall of the box, thereby reducing the wiring difficulty of the DC main control component group and the AC power distribution component group.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0030] like Figure 1 and Figure 2 As shown, the main control distribution box includes:

[0031] The housing 1 has an installation cavity, and a partition 101 is provided in the installation cavity, which divides the installation cavity into a first installation cavity 102 and a second installation cavity 103.

[0032] The DC main control component group 2, the AC power distribution component group 3, and the power supply component 4 are installed in the first mounting cavity 102, the AC power distribution component group 3 is installed in the second mounting cavity 103, and the power supply component 4 is installed in either the first mounting cavity 102 or the second mounting cavity 103. The power supply component 4 is electrically connected to the DC main control component group 2.

[0033] The first incoming line terminal group 7 and the second incoming line terminal group 8 are electrically connected to the power supply component 4 and the second incoming line terminal group 8 are electrically connected to the AC power distribution component group 3. The first incoming line terminal group 7 and the second incoming line terminal group 8 are both located on the same side wall of the enclosure 1.

[0034] As can be seen from the above embodiments, in this application embodiment, since the housing 1 has an installation cavity, and a partition 101 is provided in the installation cavity, the partition 101 divides the installation cavity into a first installation cavity 102 and a second installation cavity 103. The DC main control component group 2 is installed in the first installation cavity 102, the AC power distribution component group 3 is installed in the second installation cavity 103, and the power supply component 4 is installed in the first installation cavity 102 or the second installation cavity 103. The power supply component 4 and the DC main control component group 2 are electrically connected. Therefore, the installation cavity of the housing 1 can be divided into two independent cavities by the partition 101, so that the DC main control component group 2 and the AC power distribution component group 3 can be installed in different installation cavities and can be isolated by the partition 101. Furthermore, since the first incoming terminal group 7 and the second incoming terminal group 8 are electrically connected, the first incoming terminal group 7 is electrically connected to the power supply component 4, and the second incoming terminal group 8 is electrically connected to the AC power distribution component group 3, and both the first incoming terminal group 7 and the second incoming terminal group 8 are located on the same side wall of the enclosure 1, the first incoming terminal group 7 and the second incoming terminal group 8 can be routed through the same side wall of the enclosure 1, which facilitates the inspection and maintenance of the routing of the first incoming terminal group 7 and the second incoming terminal group 8, and makes it convenient for users to connect the wires. In summary, the main control distribution box provided in this application embodiment not only allows the DC main control component group 2 and the AC power distribution component group 3 to be installed in different mounting cavities, thus enabling the DC main control component group 2 and the AC power distribution component group 3 to be partitioned, saving the internal space utilization of the main control distribution box and reducing the difficulty of arranging the main control component group 2 and the AC power distribution component group 3 in the main control distribution box, but also allows the first incoming terminal group 7 and the second incoming terminal group 8 to be routed through the same side wall of the box body 1, thereby reducing the wiring difficulty of the DC main control component group 2 and the AC power distribution component group 3.

[0035] The enclosure 1 can be any of the following structures with mounting cavities: a square shell structure, a square box structure, etc. This application embodiment does not limit this. The operating voltage in this application embodiment refers to the voltage range required or actually borne by the electrical components under normal operating conditions.

[0036] Furthermore, the partition 101 provided in the mounting cavity can be any of the materials capable of isolating electromagnetic interference, such as conductive rubber, conductive foam, or metal. The partition 101 can divide the mounting cavity into two stacked mounting spaces, namely, the first mounting cavity 102 and the second mounting cavity 103 stacked along a third direction Z. Alternatively, the partition 101 can divide the mounting cavity into a first mounting cavity 102 and a second mounting cavity 103 arranged along a first direction X, or vice versa. This embodiment does not limit the specific arrangements. Furthermore, the surface of the partition 101 can be coated with insulating varnish to make the surface of the partition 101 in an insulating state, thus providing insulation protection for the DC main control component group 2 and the AC power distribution component group 3.

[0037] It should be noted that, according to Figure 1 In this embodiment of the invention, the X-axis and Z-axis intersect, the X-axis and Y-axis intersect, and the Y-axis and Z-axis intersect. For ease of explanation, the first direction is defined as the X-axis, the second direction as the Y-axis (which is the length direction of the main control distribution box in this embodiment), and the third direction as the Z-axis. It should be further noted that the definition of intersection in the specification, fluctuating by 10% within 90 degrees, should be understood as perpendicular. That is, the angle between the defined first and second directions, and the angle between the defined first and third directions, should be understood as intersecting within 80 to 90 degrees. In some embodiments, the X-axis and Y-axis are preferably perpendicular, the Y-axis and Z-axis are preferably perpendicular, and the X-axis and Z-axis are preferably perpendicular.

[0038] The DC main control component group 2 includes electrical components such as DC circuit breakers, switching elements, DC fuses, and DC contactors. The AC power distribution component group 3 may include electrical components such as AC circuit breakers, switching elements, AC fuses, AC contactors, and AC converters. This embodiment does not limit the specific components in this application. The DC main control component group 2 can be installed in the first mounting cavity 102 by means of threaded connection, riveting, or snap-fit. The AC power distribution component group 3 can be installed in the second mounting cavity 103 by means of threaded connection, riveting, or snap-fit. This embodiment does not limit the specific components in this application. This allows the DC main control component group 2 and the AC power distribution component group 3 to be separated, avoiding mutual interference and facilitating the assembly of the main control distribution box.

[0039] In some embodiments, the main control distribution box further includes a load terminal group 5 and a terminal group 6. The load terminal group 5 is electrically connected to the DC main control element group 2 or the AC power distribution element group 3 through the terminal group 6. When the circuit between the AC power distribution element group 3 and the load terminal group 5 is disconnected, the load terminal group 5 is electrically connected to the DC main control element group 2 through the terminal group 6.

[0040] In this embodiment, the load terminal group 5 may include load terminals located outside the main control distribution box or load terminals located inside the main control distribution box. Load terminals located outside the main control distribution box may include power-consuming components such as water immersion modules, battery management modules, IO modules (input / output modules), switches, remote control communication modules, heat dissipation components 9, and temperature sensors. Load terminals located outside the main control distribution box may include other power-consuming components such as energy management systems, fire suppression systems, and LED strips; this embodiment does not limit the specific components. For example, when the load terminals located inside the main control distribution box include IO modules (input / output modules), they can quickly communicate with external input signal devices to obtain signals from external smoke detectors, heat-sensing aerosol fire extinguishing devices, water immersion devices, etc. Simultaneously, these signals are aggregated and relayed to the upper-level energy management system, where the upper-level system performs logic processing to ensure the safety and stability of the main control distribution box.

[0041] Furthermore, the terminal block 6 may include pluggable terminals, barrier terminals, terminal blocks, etc. This application does not limit the specific type of terminal block. The power supply assembly 4 can be installed in either the first mounting cavity 102 or the second mounting cavity 103. The power supply assembly 4 is a type of battery, used to supply power to the load terminal block 5 via the DC main control component assembly 2 through the power supply assembly 4 located inside the housing 1 in the event of a circuit failure between the AC power distribution component group 3 and the terminal block 6.

[0042] Thus, since the main control distribution box also includes a load terminal group 5 and a terminal group 6, the load terminal group 5 is electrically connected to the DC main control component group 2 or the AC power distribution component group 3 through the terminal group 6. When the circuit between the AC power distribution component group 3 and the load terminal group 5 is broken, the load terminal group 5 is electrically connected to the DC main control component group 2 through the terminal group 6. Therefore, when the circuit between the AC power distribution component group 3 and the terminal group 6 is broken, the load terminal group 5 is electrically connected to the DC main control component group 2 through the terminal group 6. Thus, in the event of a circuit failure between the AC power distribution component group 3 and the terminal group 6, the power supply component 4 installed inside the box 1 can supply power to the load terminal group 5 through the DC main control component group 2, thereby preventing the main control distribution box from being affected by a large-scale power outage.

[0043] It should be noted that this application mainly supplies power to the load terminal group 5 through the external power grid 12, the terminal group 6, and the AC power distribution component group 3. Therefore, the failure of the circuit between the AC power distribution component group 3 and the terminal group 6 in this application can be understood as the external power grid 12 being unable to cut off power, that is, the external power grid 12 being unable to supply power to the load terminal group 5 through the terminal group 6 and the AC power distribution component group 3. The large-scale power failure of the main control distribution box can be understood as the external power grid 12 being cut off.

[0044] In some embodiments, the terminal block 6, the first inlet terminal block 7, and the second inlet terminal block 8 are all disposed on the same side wall of the housing 1.

[0045] In this embodiment, since the terminal block 6, the first inlet terminal block 7, and the second inlet terminal block 8 are all located on the same side wall of the housing 1, the terminal block 6, the first inlet terminal block 7, and the second inlet terminal block 8 can be routed through the same side wall of the housing 1, which facilitates the inspection and maintenance of the wiring of the terminal block 6, the first inlet terminal block 7, and the second inlet terminal block 8, and makes it convenient for users to connect the wires.

[0046] In addition, the main control distribution box may also include a third incoming terminal group for wiring with the battery. The third incoming terminal group, load terminal group 5, first incoming terminal group 7, and second incoming terminal group 8 are all located on the same side wall of the box body 1, further facilitating wiring by the user. Furthermore, the main control distribution box may also include a handle 11, allowing the load terminal group 5, first incoming terminal group 7, second incoming terminal group 8, and handle 11 to be installed on the same side wall of the box body 1, located at the edge of the side wall. The handle 11 not only facilitates the maintenance of the main control distribution box but also helps reduce the operation and maintenance time and cost of the main control distribution box.

[0047] In some embodiments, the main control distribution box includes intersecting first direction X and second direction Y, and a partition 101 extends along the second direction Y to divide the mounting cavity into a first mounting cavity 102 and a second mounting cavity 103 arranged along the first direction X, wherein the second direction Y is along the length direction of the main control distribution box.

[0048] In this embodiment, since the partition 101 extends along the second direction Y to divide the mounting cavity into a first mounting cavity 102 and a second mounting cavity 103 arranged along the first direction X, wherein the second direction Y is along the length direction of the main control distribution box, the length direction of the first mounting cavity 102 and the second mounting cavity 103 can be made consistent with the length direction of the mounting cavity. This allows the multiple DC main control components included in the DC main control component group 2 to be electrically connected along the second direction Y, and the multiple AC power distribution components included in the AC power distribution component group 3 to be electrically connected along the second direction Y. This makes it easier to make reasonable use of the mounting space of the first mounting cavity 102 and the second mounting cavity 103, and improves the space utilization rate inside the box 1.

[0049] In some embodiments, such as Figure 3 As shown, the main control distribution box also includes a heat dissipation component 9. Both the first mounting cavity 102 and the second mounting cavity 103 are equipped with heat dissipation components 9. The size of the first mounting cavity 102 in the first direction X is smaller than the size of the second mounting cavity 103 in the first direction X. The power supply component 4 is installed in the second mounting cavity 103. At least one heat dissipation component 9 is installed on the periphery of the power supply component 4.

[0050] In this embodiment, since both the first mounting cavity 102 and the second mounting cavity 103 are equipped with heat dissipation components 9, the DC main control component group 2 installed in the first mounting cavity 102 and the AC power distribution component group 3 installed in the second mounting cavity 103 can be cooled by the heat dissipation components 9, which helps to extend the service life of the DC main control component group 2 and the AC power distribution component group 3. Furthermore, since the dimension of the first mounting cavity 102 in the first direction X is smaller than the dimension of the second mounting cavity 103 in the first direction X, and the power supply component 4 is installed in the second mounting cavity 103, with at least one heat dissipation component 9 installed on its periphery, the installation space of the second mounting cavity 103 can be reasonably utilized, allowing the second mounting cavity 103 to install not only the heat dissipation component 9 but also the power supply component 4. Simultaneously, the presence of at least one heat dissipation component 9 on the periphery of the power supply component 4 facilitates heat dissipation, further extending its service life. It should be noted that the heat dissipation component 9 can be a liquid-cooled heat dissipation component, an air-cooled heat dissipation component, a contact-type heat dissipation component, etc., and this embodiment does not limit this.

[0051] In some embodiments, the main control distribution box further includes a temperature sensor, which is installed in at least one of the first mounting cavity 102 and the second mounting cavity 103, and the temperature sensor is electrically connected to the heat dissipation assembly 9.

[0052] In this embodiment, since the temperature sensor is installed in at least one of the first mounting cavity 102 and the second mounting cavity 103, and the temperature sensor and the heat dissipation assembly 9 are electrically connected, the temperature in the mounting cavity can be sensed in real time by the temperature sensor, which facilitates the timely opening and closing of the heat dissipation assembly 9 and facilitates the control of the temperature in the mounting cavity.

[0053] In some embodiments, terminal block 6 is a terminal board, and DC main control component group 2 and AC power distribution component group 3 are both electrically connected to the terminal board.

[0054] In this embodiment, since the terminal block 6 is a terminal board, the DC main control component group 2 and the AC power distribution component group 3 are both electrically connected to the terminal board. Therefore, the connection with the load terminal group 5 can be directly achieved through the terminal board, which facilitates disassembly, maintenance and management.

[0055] In some embodiments, the DC main control component group 2 includes a plurality of DC main control components, and the AC power distribution component group 3 includes a plurality of AC power distribution components. The plurality of DC main control components are electrically connected through terminal blocks, and the plurality of AC power distribution components are electrically connected through terminal blocks.

[0056] In this embodiment, since the DC main control component group 2 includes multiple DC main control components and the AC power distribution component group 3 includes multiple AC power distribution components, the multiple DC main control components are electrically connected through terminal blocks, and the multiple AC power distribution components are electrically connected through terminal blocks. Therefore, the line resistance between the multiple AC power distribution components and the multiple DC main control components can be reduced, which is beneficial to stabilizing the current and can improve the working stability and reliability of the main control distribution box, and is convenient for installation and maintenance.

[0057] In some embodiments, such as Figure 4 As shown, the DC main control component group 2 includes a first circuit breaker 21 and a switching power supply 22, the AC power distribution component group 3 includes a second circuit breaker 31 and an AC voltage converter 32, and the main control distribution box also includes a circuit switch 10. The circuit switch 10 includes a first input terminal 1001, a second input terminal 1002 and an output terminal 1003. The second circuit breaker 31 is electrically connected to the first input terminal 1001 through the AC voltage converter 32. The first circuit breaker 21 is electrically connected in the electrical connection line between the power supply component 4 and the switching power supply 22. The first circuit breaker 21 is electrically connected to the second input terminal 1002 through the switching power supply 22, and the output terminal 1003 is electrically connected to the terminal block 6.

[0058] In this embodiment, since the second circuit breaker 31 is electrically connected to the first input terminal 1001 through the AC voltage converter 32, and the first circuit breaker 21 is electrically connected in the electrical connection line between the power supply component 4 and the switching power supply 22, and the first circuit breaker 21 is electrically connected to the first input terminal 1001 through the switching power supply 22, and the output terminal 1003 is electrically connected to the terminal group 6, in the event of a circuit failure between the AC power distribution component group 3 and the terminal group 6, the second circuit breaker 31 can be disconnected from the electrical connection line between itself and the first input terminal 1001 of the circuit switch 10, and the electrical connection line between the first circuit breaker 21 and the switching power supply 22 can be closed. This allows the power supply component 4 to be electrically connected to the switching power supply 22 through the first circuit breaker 21. After conversion by the switching power supply 22, the power can be output from the second input terminal 1002 to the output terminal 1003, and finally output to the terminal group 6 to supply power to the load terminal group 5. Thus, through the above embodiments, in the event of a circuit failure between the AC power distribution component group 3 and the terminal group 6, the power supply component 4 installed inside the enclosure 1 can supply power to the load terminal group 5 through the first circuit breaker 21, the switching power supply 22, the circuit switch 10, and the terminal group 6, thereby preventing the main control distribution box from being affected by a large-scale power outage and thus avoiding disruption to normal operation. The circuit switch 10 can be one or more electrical components such as diodes, air switches, relays, and contactors; this embodiment does not limit the specific type of circuit switch.

[0059] As can be seen from the above embodiments, in this application embodiment, since the housing 1 has an installation cavity, and a partition 101 is provided in the installation cavity, the partition 101 divides the installation cavity into a first installation cavity 102 and a second installation cavity 103. The DC main control component group 2 is installed in the first installation cavity 102, the AC power distribution component group 3 is installed in the second installation cavity 103, and the power supply component 4 is installed in the first installation cavity 102 or the second installation cavity 103. The power supply component 4 and the DC main control component group 2 are electrically connected. Therefore, the installation cavity of the housing 1 can be divided into two independent cavities by the partition 101, so that the DC main control component group 2 and the AC power distribution component group 3 can be installed in different installation cavities and can be isolated by the partition 101. Furthermore, since the first incoming terminal group 7 and the second incoming terminal group 8 are electrically connected, the first incoming terminal group 7 is electrically connected to the power supply component 4, and the second incoming terminal group 8 is electrically connected to the AC power distribution component group 3, and both the first incoming terminal group 7 and the second incoming terminal group 8 are located on the same side wall of the enclosure 1, the first incoming terminal group 7 and the second incoming terminal group 8 can be routed through the same side wall of the enclosure 1, which facilitates the inspection and maintenance of the routing of the first incoming terminal group 7 and the second incoming terminal group 8, and makes it convenient for users to connect the wires. In summary, the main control distribution box provided in this application embodiment not only allows the DC main control component group 2 and the AC power distribution component group 3 to be installed in different mounting cavities, thus enabling the DC main control component group 2 and the AC power distribution component group 3 to be partitioned, saving the internal space utilization of the main control distribution box and reducing the difficulty of arranging the main control component group 2 and the AC power distribution component group 3 in the main control distribution box, but also allows the first incoming terminal group 7 and the second incoming terminal group 8 to be routed through the same side wall of the box body 1, thereby reducing the wiring difficulty of the DC main control component group 2 and the AC power distribution component group 3.

[0060] This application provides an energy storage system, which includes a battery and a main control distribution box as described in any of the above embodiments. The battery and the main control distribution box are electrically connected.
