Description

Technical Field

[0001] This utility model belongs to the field of energy storage technology, and specifically provides an energy control module and an integrated energy storage cabinet suitable for integrated energy storage cabinets. Background Technology

[0002] Commercial and industrial integrated cabinets, also known as integrated energy storage cabinets or integrated energy storage cabinets, will be referred to as integrated energy storage cabinets in the following text for the purpose of consistency.

[0003] An integrated energy storage cabinet is a high-efficiency, integrated energy storage solution specifically designed for industrial and commercial applications. It integrates multiple functional components to optimize energy use, improve power supply reliability and economic efficiency, and promote the application of green energy. Integrated energy storage cabinets offer advantages such as high integration, peak shaving and valley filling, and ensuring uninterrupted power supply to electrical facilities.

[0004] Existing integrated energy storage cabinets typically integrate multiple components such as battery packs, power conversion systems (PCS), battery management systems (BMS), energy management systems (EMS), liquid cooling units, fire protection systems, and high-voltage boxes into a single cabinet to ensure their compactness and high efficiency.

[0005] However, existing integrated energy storage cabinets have many components, making assembly quite complicated. Utility Model Content

[0006] One objective of this invention is to solve the problem that the assembly of existing integrated energy storage cabinets is cumbersome due to the large number of components.

[0007] To achieve the above objectives, the present invention provides, in a first aspect, an energy control module suitable for an integrated energy storage cabinet, comprising an energy storage converter PCS, a battery management system (BMS), and an energy management system (EMS), wherein the energy storage converter PCS, the battery management system (BMS), and the energy management system (EMS) are relatively fixedly formed as a whole.

[0008] Optionally, the power control module further includes a housing, in which the energy storage converter PCS, the battery management system BMS, and the energy management system EMS are all arranged.

[0009] Optionally, the power control module further includes a base, and the energy storage converter PCS, the battery management system BMS, and the energy management system EMS are respectively fixedly connected to the base.

[0010] Optionally, the power control module further includes at least one connecting component, through which the energy storage converter PCS, the battery management system BMS, and the energy management system EMS are fixedly connected together.

[0011] Optionally, the energy storage converter (PCS), the battery management system (BMS), and the energy management system (EMS) are distributed horizontally.

[0012] Optionally, the energy storage converter PCS, the battery management system BMS, and the energy management system EMS are distributed along a preset direction, which is parallel to the horizontal direction.

[0013] Optionally, the power control module further includes a high-voltage box, which is fixedly integrated with the energy storage converter PCS, the battery management system BMS, and the energy management system EMS.

[0014] Optionally, the high-voltage box, the energy storage converter PCS, the battery management system BMS, and the energy management system EMS are distributed horizontally.

[0015] In a second aspect, this utility model provides an integrated energy storage cabinet, comprising:

[0016] Cabinet;

[0017] At least one battery pack is installed in the cabinet;

[0018] The power control module described in any one of the first aspects is installed in the cabinet and is used to control the charging and discharging of the battery pack.

[0019] Optionally, the power control module is arranged on the top or bottom side of the at least one battery pack.

[0020] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, the power control module of this utility model forms a whole by relatively fixing the energy storage converter PCS, battery management system BMS, and energy management system EMS together. This allows the utility model to pre-assemble the energy storage converter PCS, battery management system BMS, and energy management system EMS into a whole, thereby forming the power control module. Therefore, this utility model facilitates the assembly of the integrated energy storage cabinet by pre-assembling the energy storage converter PCS, battery management system BMS, and energy management system EMS into a whole and then assembling this whole unit onto the cabinet of the integrated energy storage cabinet.

[0021] Those skilled in the art will also understand that, compared to "assembling the energy storage converter PCS, battery management system BMS, and energy management system EMS separately onto the rack of the integrated energy storage cabinet," this invention can be divided into at least two assembly stages: first, assembling the energy storage converter PCS, battery management system BMS, and energy management system EMS into a single unit (i.e., the power control module), and then assembling the power control module onto the rack of the integrated energy storage cabinet. In other words, the power control module of this invention can be assembled as an independent module onto the rack of the integrated energy storage cabinet, simplifying the assembly steps of the integrated energy storage cabinet.

[0022] Furthermore, by distributing the energy storage converter PCS, battery management system BMS, and energy management system EMS horizontally, the stacking of these components in the vertical direction is avoided, reducing the height of the power control module and consequently reducing the height of the integrated energy storage cabinet.

[0023] Furthermore, by fixing the high-voltage box to the energy storage converter PCS, battery management system BMS, and energy management system EMS to form a whole, the power control module of this utility model integrates more functional modules, further simplifying the assembly steps of the integrated energy storage cabinet.

[0024] Furthermore, by arranging the power control module on the top or bottom side of at least one battery pack, the horizontal dimensions of the integrated energy storage cabinet can be effectively reduced, thereby reducing the floor space occupied by the integrated energy storage cabinet.

[0025] Other beneficial effects of this utility model will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand the improvement purpose, features and advantages of this utility model. Attached Figure Description

[0033] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0035] like Figure 1 As shown, in some embodiments of this utility model, the integrated energy storage cabinet 001 includes at least one battery pack 100, a liquid-cooled temperature control module 200, an energy control module 300, and a cabinet body 400.

[0036] Among them, the battery pack 100 is the core of energy storage and can use lithium-ion batteries to store a large amount of electrical energy.

[0037] Furthermore, in this utility model, the number of battery packs 100 can be any feasible number, such as one, two, three, five, etc.

[0038] The liquid-cooled temperature control module 200 is used to cool all the battery packs 100.

[0039] Although not shown in the figures, in some embodiments of this invention, the liquid-cooled temperature control module 200 includes a liquid-cooling unit filled with coolant. The liquid-cooling unit may also include a circulation pump to drive the coolant flow and cool the battery pack 100. Furthermore, the liquid-cooling unit may also include a storage tank to store the coolant.

[0040] It should be noted that since existing integrated energy storage cabinets generally have liquid cooling units, which are well known to those skilled in the art and are common knowledge in this field, they will not be described in detail here.

[0041] Furthermore, in some embodiments of this utility model, the power control module 300 is used to control the charging and discharging of the battery pack 100.

[0042] like Figure 1 As shown, in some embodiments of this utility model, the cabinet 400 is defined by a top compartment 401, a middle compartment 402 and a bottom compartment 403 distributed from top to bottom, respectively accommodating at least one battery pack 100, a liquid-cooled temperature control module 200 and a power control module 300, thereby allowing at least one battery pack 100, a liquid-cooled temperature control module 200 and a power control module 300 to be located in different compartments.

[0043] Those skilled in the art will understand that by defining a top compartment 401, a middle compartment 402, and a bottom compartment 403 within the cabinet 400 to respectively house the battery pack 100, the liquid-cooled temperature control module 200, and the power control module 300, the battery pack 100, the liquid-cooled temperature control module 200, and the power control module 300 can be located in different compartments. Since the liquid-cooled temperature control module 200 of this invention is arranged in a separate compartment, in the event of a leak, the coolant will only remain in the compartment containing the liquid-cooled temperature control module 200, preventing short circuits and fires in the battery pack 100 and the power control module 300, thus ensuring the safe use of the integrated energy storage cabinet 001.

[0044] Continue reading Figure 1 In some embodiments of this utility model, all battery packs 100 are arranged in the middle compartment 402, the liquid cooling temperature control module 200 is arranged in the top compartment 401, and the power control module 300 is arranged in the bottom compartment 403.

[0045] Those skilled in the art will understand that by arranging the battery pack 100 in the middle compartment 402, the liquid-cooled temperature control module 200 in the top compartment 401, and the power control module 300 in the bottom compartment 403, it is not only convenient for the power control module 300 to be connected to the AC power at a lower position, but also reduces the height of the battery pack 100, thereby lowering the center of gravity of the integrated energy storage cabinet 001 and ensuring the stability of the integrated energy storage cabinet 001.

[0046] In addition, in other embodiments of this utility model, those skilled in the art may arrange the liquid cooling temperature control module 200 in the bottom compartment 403 and the power control module 300 in the top compartment 401 as needed.

[0047] Alternatively, those skilled in the art may arrange all the battery packs 100 in the top compartment 401, the liquid-cooled temperature control module 200 in the middle compartment 402, and the power control module 300 in the bottom compartment 403 as needed.

[0048] Alternatively, those skilled in the art may arrange all the battery packs 100 in the top compartment 401, the liquid-cooled temperature control module 200 in the bottom compartment 403, and the power control module 300 in the middle compartment 402 as needed.

[0049] Alternatively, those skilled in the art may arrange all the battery packs 100 in the bottom compartment 403, the liquid-cooled temperature control module 200 in the top compartment 401, and the power control module 300 in the middle compartment 402 as needed.

[0050] Alternatively, those skilled in the art may arrange all the battery packs 100 in the bottom compartment 403, the liquid-cooled temperature control module 200 in the middle compartment 402, and the power control module 300 in the top compartment 401 as needed.

[0051] Continue reading Figure 1 In some embodiments of this utility model, the integrated energy storage cabinet 001 further includes at least one liquid cooling component 500 and at least one liquid cooling pipeline 600 connecting each liquid cooling component 500 to the liquid cooling temperature control module 200, and each liquid cooling component 500 corresponds to a battery pack 100.

[0052] Specifically, there are multiple liquid cooling components 500 and liquid cooling pipes 600, and each battery pack 100 is provided with a liquid cooling component 500 on its bottom side. At least one liquid cooling pipe 600 is provided on the left and right sides of at least one battery pack 100, so that each liquid cooling component 500 and the liquid cooling temperature control module 200 form a loop for the circulation of coolant, thereby ensuring that each battery pack 100 can be effectively cooled.

[0053] Of the components, one side of the liquid cooling pipe 600 on the left and right sides of the battery pack 100 is a low-temperature pipe, used to introduce low-temperature coolant into the liquid cooling component 500. The other side of the liquid cooling pipe 600 on the left and right sides of the battery pack 100 is a high-temperature pipe, used to drain the high-temperature coolant from the liquid cooling component 500.

[0054] In addition, in other embodiments of this utility model, those skilled in the art may, as needed, provide at least one liquid cooling component 500 on the top, left or right side of each battery pack 100.

[0055] Alternatively, those skilled in the art may, as needed, provide at least one liquid cooling component 500 on the bottom, top, left and / or right sides of each battery pack 100.

[0056] Furthermore, in some embodiments of this utility model, the liquid cooling component 500 may be a plate-shaped component to increase the contact area between the liquid cooling component 500 and the battery pack 100, thereby increasing the heat exchange efficiency between the liquid cooling component 500 and the battery pack 100.

[0057] Continue reading Figure 1 In some embodiments of this utility model, the integrated energy storage cabinet 001 also includes a power distribution box 700 arranged in the same compartment as the power control module 300.

[0058] Those skilled in the art will understand that by arranging the distribution box 700 and the power control module 300 in the same compartment, the coolant leaking from the liquid-cooled temperature control module 200 is prevented from coming into contact with the distribution box 700, thus ensuring the safe use of the integrated energy storage cabinet 001.

[0059] Furthermore, in some embodiments of this utility model, the distribution box 700 is equipped with an air switch, a surge protection device (SPD), an electricity meter, and an uninterruptible power supply (UPS).

[0060] Those skilled in the art will also understand that the distribution box 700 generally has functions such as power distribution, circuit protection, control, metering and monitoring.

[0061] Regarding the power distribution function, the distribution box 700 is responsible for distributing the main power supply to the various electrical devices and subsystems within the integrated energy storage cabinet 001, ensuring that each part can obtain a stable and appropriate power supply.

[0062] Regarding circuit protection functions, the circuit breakers, leakage current protectors, and other protective devices built into the 700 distribution box can quickly cut off the power supply when abnormal conditions such as circuit overload, short circuit, and leakage occur, preventing electrical fires, equipment damage, and electric shock accidents, and ensuring personal and property safety.

[0063] Regarding control functions, the switching equipment in the distribution box 700 can easily control the on / off of each circuit, enabling the start, stop, or switching operations of the equipment in the integrated energy storage cabinet 001, facilitating daily management and maintenance.

[0064] Regarding metering and monitoring functions, the 700 distribution box can monitor and record power consumption in real time by installing electricity meters or other metering devices, providing users with energy consumption data to help optimize energy efficiency and cost control.

[0065] Since existing integrated energy storage cabinets 001 generally have a distribution box 700, which is well known to those skilled in the art and is common knowledge in this field, this utility model will not elaborate further.

[0066] Continue reading Figure 1 In some embodiments of this utility model, the integrated energy storage cabinet 001 also includes a fire protection system 800 arranged in the same compartment as the battery pack 100. The fire protection system 800 generally includes piping for guiding the flow of powdered, liquid, and / or gaseous fire extinguishing materials.

[0067] Those skilled in the art will understand that by arranging the fire protection system 800 and the battery pack 100 in the same compartment, compared to arranging the fire protection system 800 and the battery pack 100 in different compartments, the piping of the fire protection system 800 is effectively shortened, the reaction time of the fire protection system 800 in the event of a fire in the battery pack 100 is shortened, and the safety of the integrated energy storage cabinet 001 is improved.

[0068] Furthermore, although not shown in the figures, in some embodiments of this invention, the fire protection system 800 may include a thermal runaway detection alarm system and a fire suppression system.

[0069] Among them, the thermal runaway detection and alarm system uses highly sensitive sensors to monitor the temperature, voltage and current changes of the battery pack 100, as well as the composition of ambient gases in real time. It can issue an early warning in the early stage of thermal runaway of the battery pack 100 and promptly detect potential fire risks.

[0070] Fire suppression systems can include perfluorohexanone extinguishing devices, aerosol extinguishing devices, dry powder extinguishing devices, and inert gas extinguishing devices. Once signs of fire are detected, the fire suppression system will immediately activate the corresponding fire suppression measures. For example, inert gases (such as nitrogen), dry powder, fine water mist, or specialized cleaning extinguishing agents can be used to directly target the point of ignition and quickly extinguish the fire while minimizing the impact on surrounding equipment and the environment.

[0071] Since existing integrated energy storage cabinets 001 generally have fire protection systems 800, which are well known to those skilled in the art and are common knowledge in this field, this utility model will not elaborate further.

[0072] Continue reading Figure 1 In some embodiments of this utility model, the fire protection system 800 is arranged on the top side of all battery packs 100; and / or, the fire protection system 800 is located in the middle of the battery packs 100 in the left-right direction.

[0073] Those skilled in the art will understand that by arranging the fire suppression system 800 on the top side of the battery pack 100 and positioning the fire suppression system 800 in the middle of the battery pack 100 in the left-right direction, the powder, liquid and / or gaseous fire extinguishing materials sprayed from the fire suppression system 800 can be rapidly diffused throughout the entire central compartment 402 by their own gravity, thereby providing comprehensive fire suppression and isolating the fire source for all battery packs 100 in the central compartment 402.

[0074] In addition, in other embodiments of this utility model, those skilled in the art may, as needed, position the fire protection system 800 to the left or right of the battery pack 100 in the left-right direction.

[0075] In addition, in other embodiments of this utility model, those skilled in the art may omit one of the top compartment 401, the middle compartment 402 and the bottom compartment 403 as needed, so that other electrical components of the energy storage integrated cabinet 001 can be arranged in the same compartment while the liquid-cooled temperature control module 200 has an independent compartment.

[0076] like Figures 2 to 5 As shown, in this utility model, the power control module 300 includes an energy storage converter PCS310, a battery management system BMS320, and an energy management system EMS330, and the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are relatively fixedly formed as a whole.

[0077] Among them, the energy storage converter PCS310 is used to realize the conversion between DC and AC power and control the charging and discharging process.

[0078] The battery management system (BMS320) is used to monitor the status of the battery pack 100 and prevent overcharging and over-discharging of the battery pack 100, thereby extending the service life of the battery pack 100.

[0079] Among them, the energy management system EMS330 is responsible for monitoring the operating status of the integrated energy storage cabinet 001, performing data analysis, optimizing the charging and discharging strategy of the battery pack 100, and ensuring the safe, stable and economical operation of the system.

[0080] Those skilled in the art will understand that the power control module 300 of this invention forms a single unit by relatively fixing the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 together. This allows the power control module 300 to be pre-assembled into a single unit. Therefore, by pre-assembling the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 into a single unit, and then assembling this single unit onto the cabinet of the integrated energy storage cabinet 001, the assembly of the integrated energy storage cabinet 001 is facilitated.

[0081] Those skilled in the art will also understand that, compared to "assembling the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 separately onto the rack of the integrated energy storage cabinet 001," this invention can be divided into at least two assembly nodes: first, assembling the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 into a single unit (i.e., the power control module 300), and then assembling the power control module 300 onto the rack of the integrated energy storage cabinet 001. In other words, the power control module 300 of this invention can be assembled as an independent module onto the rack of the integrated energy storage cabinet 001, simplifying the assembly steps of the integrated energy storage cabinet 001.

[0082] The following continues to refer to... Figures 2 to 5 The following example illustrates the power control module 300 in this utility model.

[0083] like Figure 2 As shown, in the first example of this utility model, the power control module 300 also includes a housing 340, in which the energy storage converter PCS 310, the battery management system BMS 320 and the energy management system EMS 330 are all arranged.

[0084] The housing 340 can be any feasible structure. For example, the housing 340 includes a bottom shell and a top cover. After the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 are installed in the bottom shell, the top cover and the bottom shell are installed together by any feasible connection method such as bolt connection, screw connection, or snap-fit.

[0085] Preferably, the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are arranged as compactly as possible within the housing 340 to minimize the volume of the power control module 300.

[0086] Continue reading Figure 2 In the first example of the utility model, the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are distributed along the horizontal direction X.

[0087] Those skilled in the art will understand that by distributing the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 along the horizontal direction X, the stacking of the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 in the vertical direction is avoided, thereby reducing the height of the power control module 300 and consequently reducing the height of the integrated energy storage cabinet 001.

[0088] In this context, the horizontal direction X can be understood as a plane that is roughly parallel to the horizontal plane.

[0089] Continue reading Figure 2 In the first example of the utility model, the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are distributed along a preset direction Y.

[0090] The preset direction Y is parallel to the horizontal direction X, so that the size of the power control module 300 is as small as possible in the direction perpendicular to the preset direction Y.

[0091] Furthermore, the preset direction Y can be compared with... Figure 1 The energy storage integrated cabinet 001 shown is parallel to the left and right directions, and can also be aligned with... Figure 1 The front and back directions of the energy storage integrated cabinet 001 shown are parallel.

[0092] In a specific embodiment of the first example of the utility model, the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are sequentially and closely inserted into the housing 340, thereby forming a whole with the help of the housing 340. Specifically, in the preset direction Y, the dimensions of the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are adapted to the dimensions of the housing 340, so that after the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are installed in the housing 340, they are clamped by the housing 340. In the direction perpendicular to the preset direction Y and parallel to the horizontal direction X, the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 are also respectively matched with the dimensions of the housing 340, so as to be clamped by the housing 340.

[0093] like Figure 3 As shown, in the second example of this utility model, with Figure 2 Unlike the first example shown, the power control module 300 also includes a base 350, replacing the housing 340 in the first example. The energy storage converter PCS 310, the battery management system BMS 320, and the energy management system EMS 330 are fixedly connected to the base 350.

[0094] For example, in the second example of this utility model, the base 350 is provided with three fixing positions to fix the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 respectively.

[0095] Furthermore, the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 can each be fixed to the device in any feasible manner. For example, bolted connections, snap-fit ​​connections, plug-in connections, etc., can be used.

[0096] For example, the base 350 is provided with three slots, which correspond to the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 respectively, and are interference-fitted so that after the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 are inserted into the corresponding slots, they are locked with the base 350.

[0097] like Figure 4 As shown, in the third example of this utility model, with Figure 2Unlike the first example shown, the power control module 300 also includes at least one connecting member 360, replacing the housing 340 in the first example. The energy storage converter PCS 310, the battery management system BMS 320, and the energy management system EMS 330 are fixedly connected together via at least one connecting member 360.

[0098] Furthermore, the energy storage converter PCS310, the battery management system BMS320, and the energy management system EMS330 can be simultaneously fixed to the same connecting member 360, or they can be fixed together by means of at least two connecting members 360.

[0099] Furthermore, in the third example of this utility model, the connecting member 360 can be a plate-shaped member.

[0100] In an exemplary embodiment of this invention, the connecting member 360 is provided with a threaded hole, and the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 are each provided with a through hole. A connecting member 360 is provided between each adjacent pair of the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330, so that bolts can pass through the through holes on the energy storage converter PCS310, battery management system BMS320, or energy management system EMS330 and be tightened into the threaded holes on the connecting member 360, thereby fixing the energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 into a single unit.

[0101] like Figure 5 As shown, in the fourth example of this utility model, with Figure 2 Unlike the first example shown, the power control module 300 also includes a high-voltage box 370, which is fixedly integrated with the energy storage converter PCS 310, the battery management system BMS 320 and the energy management system EMS 330.

[0102] Furthermore, the high-voltage box 370, energy storage converter PCS310, battery management system BMS320, and energy management system EMS330 are distributed along the horizontal direction X. Specifically, they can be distributed along a preset direction Y.

[0103] Furthermore, the high-voltage box 370, energy storage converter PCS310, battery management system BMS320 and energy management system EMS330 can be fixed together as a whole module using the housing 340 in the first example.

[0104] In addition, those skilled in the art can, as needed, fix the high-voltage box 370, energy storage converter PCS310, battery management system BMS320 and energy management system EMS330 together using the base 350 or connecting member 360 in the second example to form an integral module.

[0105] It should be noted that in this invention, the high-voltage box 370 is an intermediate unit connecting the battery pack 100 and the energy storage converter PCS310, participating in the conversion and distribution of high-voltage electrical energy to ensure that electrical energy is supplied to the power grid or load at an appropriate voltage level and quality.
