Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage, and specifically provides an integrated energy storage cabinet. Background Art

[0002] The full name of the industrial and commercial integrated cabinet is the industrial and commercial integrated energy storage cabinet, also known as the energy storage integrated cabinet. In order to achieve the uniformity of terminology, the industrial and commercial integrated cabinets are described as energy storage integrated cabinets in the following text.

[0003] The integrated energy storage cabinet is an efficient and integrated energy storage solution designed for industrial and commercial sites. It integrates multiple functional components to optimize energy use, improve power supply reliability and economic benefits, and promote the application of green energy. The integrated energy storage cabinet has the advantages of high integration, peak shaving and valley filling, and ensuring uninterrupted power supply to power facilities.

[0004] Existing integrated energy storage cabinets usually integrate multiple components such as battery packs, energy storage inverter PCS (Power Conversion System), battery management system BMS (Battery Management System), energy management system EMS (Energy Management System), liquid cooling unit, fire protection system, high-voltage box, etc. into one cabinet to ensure its compactness and efficiency.

[0005] However, the existing integrated energy storage cabinet has a poor layout and still has the problem of large size. In addition, when the liquid cooling unit leaks, the coolant is likely to flow to the battery pack, high-voltage box and other components, causing short circuits, fires, or even explosions, which is less safe. Utility Model Content

[0006] One purpose of the utility model is to solve the problem that the existing energy storage integrated cabinet has potential safety hazards when the liquid cooling unit leaks.

[0007] In order to achieve the above object, the utility model provides an energy storage integrated cabinet comprising:

[0008] at least one battery pack;

[0009] a liquid cooling temperature control module, used to cool the at least one battery pack;

[0010] A power control module, used to control the charging and discharging of the at least one battery pack;

[0011] The cabinet is defined by a top chamber, a middle chamber and a bottom chamber which are sequentially distributed from top to bottom to respectively accommodate the at least one battery pack, the liquid cooling temperature control module and the electric energy control module, so that the at least one battery pack, the liquid cooling temperature control module and the electric energy control module are respectively located in different chambers.

[0012] Optionally, the at least one battery pack is arranged in the middle compartment.

[0013] Optionally, the liquid cooling temperature control module is arranged in the bottom chamber, and the power control module is arranged in the top chamber.

[0014] Optionally, the liquid cooling temperature control module is arranged in the top chamber, and the power control module is arranged in the bottom chamber.

[0015] Optionally, the integrated energy storage cabinet further includes at least one liquid cooling component and at least one liquid cooling pipeline connecting each of the liquid cooling components with the liquid cooling temperature control module, and each of the liquid cooling components corresponds to one of the battery packs.

[0016] Optionally, at least one of the liquid-cooling components is respectively provided on the bottom side, top side, left side and / or right side of each of the battery packs; and / or, at least one of the liquid-cooling pipelines is respectively provided on the left side and right side of at least one of the battery packs, so that a loop for circulating cooling liquid is formed between each of the liquid-cooling components and the liquid-cooling temperature control module.

[0017] Optionally, the integrated energy storage cabinet further includes a distribution box arranged in the same compartment as the power control module.

[0018] Optionally, the integrated energy storage cabinet also includes a fire protection system arranged in the same compartment as the battery pack.

[0019] Optionally, the fire fighting system is arranged on the top side of the at least one battery pack; and / or,

[0020] The fire fighting system is located at a middle position, a left position, and a right position of the at least one battery pack in the left-right direction.

[0021] Optionally, the power control module includes a power storage converter PCS, a battery management system BMS, an energy management system EMS and a high-voltage box.

[0022] Based on the foregoing description, those skilled in the art can understand that in the aforementioned technical solution of the present invention, the cabinet is defined as a top chamber, a middle chamber and a bottom chamber to accommodate the battery pack, the liquid cooling temperature control module and the power control module respectively, so that the battery pack, the liquid cooling temperature control module and the power control module can be located in different chambers respectively. Since the liquid cooling temperature control module of the present invention is arranged in a separate chamber, when it leaks, the coolant will only remain in the chamber where the liquid cooling temperature control module is located, and will not cause a short circuit or fire in the battery pack and the power control module, thereby ensuring the safety of the energy storage cabinet.

[0023] Furthermore, by arranging the battery pack in the middle compartment, the liquid cooling temperature control module in the top compartment, and the power control module in the bottom compartment, it is convenient for the power control module to connect to the lower AC power, and the height of the battery pack is reduced, thereby reducing the center of gravity height of the energy storage cabinet and ensuring the stability of the energy storage cabinet.

[0024] Furthermore, by arranging the power distribution box and the power control module in the same compartment, the coolant leaked from the liquid-cooled temperature control module is prevented from contacting the power distribution box, thereby ensuring the safe use of the energy storage integrated cabinet.

[0025] Furthermore, by arranging the fire-fighting system and the battery pack in the same compartment, compared to arranging the fire-fighting system and the battery pack in different compartments, the pipes of the fire-fighting system are effectively shortened, the reaction time of the fire-fighting system when the battery pack catches fire is shortened, and the safety of the energy storage cabinet is improved.

[0026] Furthermore, the utility model effectively reduces the horizontal size of the energy storage cabinet by distributing most of the components in the cabinet body up and down as a whole, so that the energy storage cabinet occupies a smaller area, and the energy storage cabinet can be installed in a smaller space, allowing for more installation scenarios.

[0027] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

For example, the terms "install", "connect", "connect" and "fix", unless otherwise specifically described, can specifically be any feasible connection form such as bolt connection, screw connection, welding, plug-in, riveting, melting, and clamping.

[0037] like Figure 1 As shown, in some embodiments of the present invention, the integrated energy storage cabinet 001 includes at least one battery pack 100 , a liquid cooling temperature control module 200 , a power control module 300 and a cabinet body 400 .

[0038] The battery pack 100 is the core of energy storage and can use lithium-ion batteries to store a large amount of electrical energy.

[0039] Furthermore, in the present invention, the number of battery packs 100 can be any feasible number, such as one, two, three, five, etc.

[0040] The liquid cooling temperature control module 200 is used to cool all the battery packs 100 .

[0041] Although not shown in the figure, in some embodiments of the present invention, the liquid cooling 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 to flow through the circulation pump to cool the battery pack 100. Furthermore, the liquid cooling unit may also include a liquid storage tank to store the coolant through the liquid storage tank.

[0042] It should be noted that, since the existing integrated energy storage cabinet 001 generally has a liquid cooling unit and is well known to those skilled in the art and is common knowledge in the art, it will not be described in detail here.

[0043] Furthermore, in some embodiments of the present invention, the power control module 300 is used to control the charging and discharging of the at least one battery pack.

[0044] like Figure 1 As shown, in some embodiments of the present invention, the cabinet 400 is defined by a top chamber 401, a middle chamber 402 and a bottom chamber 403 which are distributed in sequence from top to bottom to respectively accommodate at least one battery pack 100, a liquid cooling temperature control module 200 and a power control module 300, so that at least one battery pack 100, a liquid cooling temperature control module 200 and a power control module 300 are respectively located in different chambers.

[0045] It is understood by those skilled in the art that by defining the top chamber 401, the middle chamber 402 and the bottom chamber 403 of the cabinet body 400 to accommodate the battery pack 100, the liquid cooling temperature control module 200 and the power control module 300 respectively, the battery pack 100, the liquid cooling temperature control module 200 and the power control module 300 can be located in different chambers respectively. Since the liquid cooling temperature control module 200 of the utility model is arranged in a separate chamber, when it leaks, the coolant will only remain in the chamber where the liquid cooling temperature control module 200 is located, and will not cause a short circuit or fire in the battery pack 100 and the power control module 300, thereby ensuring the safety of the energy storage integrated cabinet 001.

[0046] Continue reading Figure 1 In some embodiments of the present invention, 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 .

[0047] Those skilled in the art will appreciate that by arranging the battery pack 100 in the middle compartment 402, the liquid cooling temperature control module 200 in the top compartment 401, and the power control module 300 in the bottom compartment 403, it is convenient for the power control module 300 to connect to the lower AC power, and the height of the battery pack 100 is reduced, thereby reducing the center of gravity height of the integrated energy storage cabinet 001 and ensuring the stability of the integrated energy storage cabinet 001.

[0048] In addition, in other embodiments of the present invention, those skilled in the art may also arrange the liquid cooling temperature control module 200 in the bottom chamber 403 and the power control module 300 in the top chamber 401 as needed.

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

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

[0051] Alternatively, those skilled in the art may also arrange all battery packs 100 in the bottom chamber 403 , arrange the liquid cooling temperature control module 200 in the top chamber 401 , and arrange the power control module 300 in the middle chamber 402 as needed.

[0052] Alternatively, those skilled in the art may also arrange all battery packs 100 in the bottom chamber 403 , arrange the liquid cooling temperature control module 200 in the middle chamber 402 , and arrange the power control module 300 in the top chamber 401 as needed.

[0053] Continue reading Figure 1 In some embodiments of the present invention, the energy storage integrated cabinet 001 also includes at least one liquid cooling component 500 and at least one liquid cooling pipeline 600 connecting each liquid cooling component 500 with the liquid cooling temperature control module 200, and each liquid cooling component 500 corresponds to a battery pack 100.

[0054] Specifically, there are multiple liquid-cooling components 500 and liquid-cooling pipelines 600, and a liquid-cooling component 500 is disposed on the bottom side of each battery pack 100, and at least one liquid-cooling pipeline 600 is disposed on the left and right sides of at least one battery pack 100, so that a loop for circulating coolant is formed between each liquid-cooling component 500 and the liquid-cooling temperature control module 200, thereby ensuring that each battery pack 100 can be effectively cooled.

[0055] Among them, one side of the liquid cooling pipeline 600 on one side of the left and right sides of the battery pack 100 is a low-temperature pipeline, which is used to introduce low-temperature coolant into the liquid cooling component 500. One side of the liquid cooling pipeline 600 on the other side of the left and right sides of the battery pack 100 is a high-temperature pipeline, which is used to guide the high-temperature coolant out of the liquid cooling component 500.

[0056] In addition, in other embodiments of the present invention, those skilled in the art may also respectively dispose at least one liquid cooling component 500 on the top side, left side or right side of each battery pack 100 as needed.

[0057] Alternatively, those skilled in the art may also respectively provide at least one liquid cooling component 500 on the bottom side, top side, left side and / or right side of each battery pack 100 as needed.

[0058] Furthermore, in some embodiments of the present invention, 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 .

[0059] Continue reading Figure 1 In some embodiments of the present invention, the integrated energy storage cabinet 001 further includes a distribution box 700 arranged in the same compartment as the power control module 300 .

[0060] Those skilled in the art can understand that by arranging the distribution box 700 and the power control module 300 in the same compartment, the coolant leaked from the liquid-cooled temperature control module 200 is prevented from contacting the distribution box 700, thereby ensuring the safe use of the energy storage cabinet 001.

[0061] Furthermore, in some embodiments of the present invention, the distribution box 700 is provided with an air switch, a surge protector SPD (Surge Protection Device), an electric meter, an uninterruptible power supply UPS (Uninterruptible Power Supply), etc.

[0062] Those skilled in the art can also understand that the distribution box 700 generally has functions such as power distribution, circuit protection, control, metering and monitoring.

[0063] Regarding the power distribution function, the distribution box 700 is responsible for distributing the power of the main power supply to various electrical equipment and subsystems in the energy storage cabinet 001, ensuring that each part can obtain a stable and appropriate power supply.

[0064] Regarding the circuit protection function, the built-in circuit breakers, leakage protectors and other protection devices in the distribution box 700 can quickly cut off the power supply when abnormal situations such as circuit overload, short circuit, leakage, etc. occur, preventing electrical fires, equipment damage and electric shock accidents, and ensuring personal and property safety.

[0065] Regarding the control function, the switch device in the distribution box 700 can conveniently control the on and off of each circuit, realize the start, stop or switch operation of the equipment in the energy storage integrated cabinet 001, and facilitate daily management and maintenance.

[0066] Regarding the metering and monitoring functions, the distribution box 700 can monitor and record electricity consumption in real time by installing an electric meter or other metering equipment, provide users with energy consumption data, and help optimize energy efficiency and cost control.

[0067] Since the existing integrated energy storage cabinet 001 generally has a distribution box 700, and is well known to those skilled in the art and is common knowledge in the art, the present invention will not elaborate on it.

[0068] Continue reading Figure 1 In some embodiments of the present invention, the energy storage integrated cabinet 001 further includes a fire fighting system 800 arranged in the same compartment as the battery pack 100. The fire fighting system 800 generally includes a pipeline for guiding the flow of powdered, liquid and / or gaseous fire extinguishing materials.

[0069] It will be understood by those skilled in the art 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 pipelines of the fire protection system 800 are effectively shortened, the reaction time of the fire protection system 800 when the battery pack 100 catches fire is shortened, and the safety of the energy storage cabinet 001 is improved.

[0070] Furthermore, although not shown in the drawings, in some embodiments of the present invention, the fire protection system 800 may include a thermal runaway detection alarm system and a fire suppression system.

[0071] Among them, the thermal runaway detection 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 the ambient gas in real time. It can issue an early warning in the early stage of thermal runaway of the battery pack 100 and detect potential fire risks in time.

[0072] Among them, the fire suppression system can include perfluorohexanone fire extinguishing devices, aerosol fire extinguishing devices, dry powder fire extinguishing devices, inert gas fire extinguishing devices, etc. Once signs of fire are detected, the fire suppression system will immediately initiate corresponding fire extinguishing measures. For example, inert gas (such as nitrogen), dry powder, fine water mist or special clean fire extinguishing agents can be used to quickly extinguish the fire directly at the fire point while reducing the impact on surrounding equipment and the environment.

[0073] Since the existing integrated energy storage cabinet 001 generally has a fire protection system 800 and is well known to those skilled in the art and is common knowledge in the art, the present invention will not elaborate on it.

[0074] Continue reading Figure 1 In some embodiments of the present invention, the fire fighting system 800 is arranged on the top side of all battery packs 100; and / or, the fire fighting system 800 is located in the middle of the battery pack 100 in the left-right direction.

[0075] It will be understood by those skilled in the art that by arranging the fire fighting system 800 on the top side of the battery pack 100 and locating the fire fighting system 800 in the middle of the battery pack 100 in the left-right direction, the powdered, liquid and / or gaseous fire extinguishing materials sprayed from the fire fighting system 800 can quickly spread to the entire middle chamber 402 by virtue of their own gravity, thereby extinguishing all battery packs 100 in the middle chamber 402 and isolating the fire source.

[0076] In addition, in other embodiments of the present invention, those skilled in the art may also position the fire protection system 800 on the left side or the right side of the battery pack 100 in the left-right direction as needed.

[0077] like Figures 2 to 5 As shown, in the present invention, the power control module 300 includes a power storage inverter PCS310, a battery management system BMS320 and an energy management system EMS330, and the power storage inverter PCS310, the battery management system BMS320 and the energy management system EMS330 are relatively fixed to form a whole.

[0078] Among them, the energy storage converter PCS310 is used to realize the conversion between direct current and alternating current and control the charging and discharging process.

[0079] The battery management system BMS320 is used to monitor the status of the battery pack 100 to prevent the battery pack 100 from being overcharged and over-discharged, so as to extend the service life of the battery pack 100.

[0080] Among them, the energy management system EMS330 is responsible for monitoring the operating status of the 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.

[0081] Those skilled in the art can understand that the power control module 300 of the present invention forms a whole by relatively fixing the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330, so that the present invention can pre-assemble the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 into a whole, thereby forming the power control module 300. Therefore, the present invention facilitates the assembly of the energy storage integrated cabinet 001 by pre-assembling the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 into a whole, and then assembling the whole into the cabinet of the energy storage integrated cabinet 001.

[0082] Those skilled in the art can also understand that, compared with "assembling the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 separately to the cabinet of the energy storage cabinet 001", the utility model can be divided into at least two assembly nodes, first assembling the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 into a whole (i.e., the power control module 300), and then assembling the power control module 300 to the cabinet of the energy storage cabinet 001. In other words, the power control module 300 of the utility model can be used as an independent module and assembled into the cabinet of the energy storage cabinet 001, which simplifies the assembly steps of the energy storage cabinet 001.

[0083] Continue to refer to Figures 2 to 5 The power control module 300 in the present invention is described by way of example.

[0084] like Figure 2 As shown, in the first example of the present utility model, the power control module 300 further includes a housing 340 , and the energy storage converter PCS310 , the battery management system BMS320 and the energy management system EMS330 are all arranged in the housing 340 .

[0085] The housing 340 may be any feasible structure. For example, the housing 340 includes a bottom housing 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 housing, the top cover and the bottom housing are installed together by any feasible connection method such as bolt connection, screw connection, and clamping.

[0086] Preferably, the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 are arranged in the housing 340 as compactly as possible to reduce the volume of the power control module 300 as much as possible.

[0087] 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.

[0088] It can be understood by those skilled in the art that by distributing the energy storage inverter PCS310, the battery management system BMS320 and the energy management system EMS330 along the horizontal direction X, the energy storage inverter PCS310, the battery management system BMS320 and the energy management system EMS330 are avoided from being stacked in the vertical direction, the height of the power control module 300 is reduced, and the height of the energy storage integrated cabinet 001 is correspondingly reduced.

[0089] The horizontal direction X may be understood as a plane substantially parallel to the horizontal plane.

[0090] 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 preset direction Y.

[0091] The preset direction Y is parallel to the horizontal direction X, so that the size of the power control module 300 in the direction perpendicular to the preset direction Y is as small as possible.

[0092] Furthermore, the preset direction Y can be Figure 1 The left and right directions of the energy storage integrated cabinet 001 shown in FIG. Figure 1 The front and rear directions of the energy storage integrated cabinet 001 shown in FIG. 1 are parallel.

[0093] In a specific implementation 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 inserted into the housing 340 in a snug manner, and thus the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 are formed into 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 the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 are clamped by the housing 340 after being installed in 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 to be clamped by the housing 340.

[0094] like Figure 3 As shown, in the second example of the present utility model, Figure 2 The difference from the first example shown in FIG. 3 is that the power control module 300 further includes a base 350 to replace 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 , respectively.

[0095] For example, in the second example of the present utility model, three fixing positions are provided on the base 350 to fix the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 respectively.

[0096] Furthermore, the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 can be fixed together with each other in any feasible manner, for example, by bolt connection, clamping connection, plug-in connection, etc.

[0097] Exemplarily, three slots are provided on the base 350, which correspond to the energy storage inverter PCS310, the battery management system BMS320 and the energy management system EMS330 respectively, and are interference fit so that after the energy storage inverter PCS310, the battery management system BMS320 and the energy management system EMS330 are inserted into the corresponding slots, they are clamped with the base 350.

[0098] like Figure 4 As shown, in the third example of the present utility model, Figure 2The difference from the first example shown in FIG. 3 is that the power control module 300 further includes at least one connecting member 360 to replace 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 by at least one connecting member 360 .

[0099] Furthermore, the energy storage converter PCS310 , the battery management system BMS320 and the energy management system EMS330 may be fixed to the same connecting member 360 at the same time, or may be fixed together by means of at least two connecting members 360 .

[0100] Furthermore, in the third example of the present invention, the connecting member 360 may be a plate-shaped member.

[0101] For example, in the third example of the utility model, a threaded hole is provided on the connecting member 360, and a through hole is provided on each of the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330. A connecting member 360 is provided between two adjacent ones of the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330, so that the bolt passes through the through hole on the energy storage converter PCS310, the battery management system BMS320 or the energy management system EMS330 and is tightened with the threaded hole on the connecting member 360, thereby fixing the energy storage converter PCS310, the battery management system BMS320 and the energy management system EMS330 as a whole.

[0102] like Figure 5 As shown, in the fourth example of the present utility model, Figure 2 The difference from the first example shown in FIG. 3 is that the power control module 300 further includes a high-voltage box 370 , which is relatively fixedly formed as a whole with the energy storage converter PCS 310 , the battery management system BMS 320 and the energy management system EMS 330 .

[0103] Furthermore, the high voltage box 370 , the energy storage converter PCS 310 , the battery management system BMS 320 and the energy management system EMS 330 are distributed along the horizontal direction X. Specifically, they may be distributed along the preset direction Y.
