Technical Field
[0001] This application relates to the field of energy storage technology, and in particular to a split-type energy storage system. Background Technology
[0002] In a power system, an energy storage system is a system that can store electrical energy and release it at a specific time and place.
[0003] In existing technologies, traditional containerized energy storage systems typically integrate all equipment, including battery clusters, battery management systems (BMS), power converters (PCS), and power distribution units, into a single standard container. However, this type of energy storage system requires transporting and deploying the entire container as a single unit. Its fixed size and weight, coupled with the container's large volume and weight, present transportation difficulties, making it unsuitable for applications with specific space, load-bearing, or transportation constraints. Furthermore, when increasing system capacity, it must be done on a container-by-container basis, preventing flexible small-scale expansion. In the event of internal equipment failure, the limited maintenance space may necessitate a complete system shutdown, impacting operational efficiency. Utility Model Content
[0004] The purpose of this application is to provide a split-type energy storage system that can physically separate and modularize the DC-side battery compartment and the AC-side component compartment, thereby reducing the system's footprint and achieving high flexibility in transportation, deployment, expansion, and maintenance.
[0005] To achieve the above objectives, this application provides a split-type energy storage system, including: a battery compartment and a device compartment;
[0006] The battery compartment includes a first cabinet, a plurality of battery packs, electrical components, and connecting cables. The first cabinet is provided with a first interface. The plurality of battery packs are placed inside the first cabinet. The electrical components are located inside the first cabinet. The connecting cables are used for electrical connection between the battery packs, the electrical components, and the first interface.
[0007] The device compartment includes a second cabinet, a converter, and an AC power distribution assembly. The converter and the AC power distribution assembly are both located inside the second cabinet. The second cabinet is provided with a second interface. The converter and the AC power distribution assembly are both electrically connected to the second interface via wires. The second interface can be electrically connected to the first interface.
[0008] In some embodiments, the width and depth of the first cabinet are the same as the width and depth of the second cabinet, the first cabinet can be placed on top of the second cabinet, and the first cabinet and the second cabinet can be combined to form an integral structure.
[0009] In some embodiments, a cooling assembly is further included, the cooling assembly including cooling pipes and a cooling unit, the cooling unit being disposed in the second cabinet, the cooling pipes being disposed in the battery compartment, the cooling pipes being able to extend into the second cabinet and being in communication with the cooling unit.
[0010] In some embodiments, the top of the first cabinet is provided with lifting lugs.
[0011] In some embodiments, a connecting block is also provided. When multiple first cabinets are distributed continuously, the connecting block can be connected to the lifting lugs of two adjacent first cabinets respectively, so that the two adjacent first cabinets are fixed into a whole.
[0012] In some embodiments, the bottom of the first cabinet is provided with a protrusion that can support the first cabinet.
[0013] In some embodiments, the first cabinet is equipped with a smoke sensor and a temperature sensor.
[0014] In some embodiments, the first cabinet has a first cabinet door that is rotatably engaged with the first cabinet. The first cabinet is provided with a threshold switch that can stop against the first cabinet door. The threshold switch is electrically connected to the electrical components inside the first cabinet.
[0015] In some embodiments, the bottom of the first cabinet is provided with a heat insulation layer.
[0016] In some embodiments, the bottom of the second cabinet is provided with an expansion interface, which can be electrically connected to multiple battery compartments via wires.
[0017] Compared to the aforementioned background technology, the split-type energy storage system provided in this application includes a battery compartment and a device compartment. The battery compartment includes a first cabinet, several battery packs, electrical components, and connecting cables. The first cabinet has a first interface, and the several battery packs are all placed inside the first cabinet. The electrical components are also located inside the first cabinet, and the connecting cables are used for electrical connection between the battery packs, electrical components, and the first interface. The device compartment includes a second cabinet, a converter, and an AC power distribution component. The converter and AC power distribution component are both located inside the second cabinet, and the second cabinet has a second interface. The converter and AC power distribution component are electrically connected to the second interface via wires, and the second interface can be electrically connected to the first interface. By placing the battery packs and electrical components in the first cabinet and the converter and AC power distribution component in the second cabinet, the separation and modularization of the battery compartment and the device compartment are achieved. This allows both the battery compartment and the device compartment to be transported separately, and they can also be placed in a container for transport together, offering greater flexibility compared to traditional containerized transport. The physical isolation between the battery compartment and the component compartment reduces the risk of electrical faults spreading between them. When either the battery compartment or the component compartment fails, it can be repaired or replaced independently, enabling modular maintenance and improving system availability. When the energy storage system needs expansion later, only the number of battery packs in the first cabinet or the number of battery compartments needs to be increased to increase the system's capacity, achieving flexible expansion and reducing later expansion costs. The split-type energy storage system of this application reduces the system's footprint by physically separating and modularizing the battery compartment and component compartment, achieving high flexibility in transportation, deployment, expansion, and maintenance.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.
[0034] like Figures 1 to 7As shown, the split-type energy storage system provided in this application embodiment includes a battery compartment 1 and a device compartment 2. The battery compartment 1 includes a first cabinet 101, a plurality of battery packs 102, electrical components 103, and connecting cables 104. The first cabinet 101 is provided with a first interface. The plurality of battery packs 102 are all placed inside the first cabinet 101. The electrical components 103 are located inside the first cabinet 101. The connecting cables 104 are used for electrical connection between the battery packs 102, the electrical components 103, and the first interface. The device compartment 2 includes a second cabinet 201, a converter 202, and an AC power distribution component 203. The converter 202 and the AC power distribution component 203 are both located inside the second cabinet 201. The second cabinet 201 is provided with a second interface. The converter 202 and the AC power distribution component 203 are electrically connected to the second interface through wires. The second interface can be electrically connected to the first interface.
[0035] Specifically, the first cabinet 101 has a cuboid structure, and its height is lower than that of the container. The first cabinet 101 can be installed inside the container. The bottom of the first cabinet 101 has a cable hole, and the first interface is located at the bottom of the first cabinet 101. External wires can be connected to the first interface through the cable hole. The first cabinet 101 has multiple vertically arranged storage boxes, each of which can hold a battery pack 102. The battery pack 102 is composed of multiple batteries connected in series. The multiple battery packs 102 can be connected in parallel through connecting cables 104. The parallel battery packs 102 are electrically connected to the electrical component 103 through connecting cables 104. The electrical component 103 is electrically connected to the first interface through connecting cables 104. The second cabinet 201 has a cuboid structure, and its height is lower than that of the container. The second cabinet 201 can be installed inside the container.
[0036] Understandably, by placing the battery pack 102 and electrical components 103 in the first cabinet 101, and the converter 202 and AC power distribution components 203 in the second cabinet 201, the separation and modularization of the battery compartment 1 and the component compartment 2 are achieved. This allows both the battery compartment 1 and the component compartment 2 to be transported independently, and they can also be transported together within a container, offering greater flexibility compared to traditional integrated container transport. The physical isolation between the battery compartment 1 and the component compartment 2 also reduces the risk of electrical faults spreading between them. In the event of a fault in either the battery compartment 1 or the component compartment 2, independent repair or replacement is possible, enabling modular maintenance and improving system availability. When the energy storage system needs expansion in the future, simply increasing the number of battery packs 102 in the first cabinet 101 or directly increasing the number of battery compartments 1 can increase the capacity of the energy storage system, achieving flexible expansion and reducing future expansion costs.
[0037] In some embodiments, the width and depth of the first cabinet 101 are the same as the width and depth of the second cabinet 201, the first cabinet 101 can be placed on top of the second cabinet 201, and the first cabinet 101 and the second cabinet 201 can be combined to form an integral structure.
[0038] Specifically, such as Figure 2 As shown, the width of the first cabinet 101 is less than or equal to 1000 mm, the depth of the first cabinet 101 is less than or equal to 2400 mm, the height of the first cabinet 101 is less than or equal to 2500 mm, and the height of the second cabinet 201 is less than or equal to 1000 mm.
[0039] It is understandable that the first cabinet 101 can be placed above the second cabinet 201, so that the first cabinet 101 and the second cabinet 201 are combined to form a cuboid structure. By placing the first cabinet 101 above the second cabinet 201 and increasing the capacity of the first cabinet 101 in the height direction, the overall area occupied by the energy storage system can be reduced, making the split energy storage system suitable for narrow spaces.
[0040] In some embodiments, the split energy storage system further includes a cooling assembly 3, which includes a cooling pipe 301 and a cooling unit 302. The cooling unit 302 is located in the second cabinet 201, and the cooling pipe 301 is located in the battery compartment 1. The cooling pipe 301 can extend into the second cabinet 201 and communicate with the cooling unit 302.
[0041] Specifically, such as Figure 3 and Figure 4 As shown, the cooling component 3 can be a liquid cooling system. The cooling pipe 301 surrounds the first cabinet 101 and contacts the battery pack 102 inside the first cabinet 101. The cooling pipe 301 has an inlet end and an outlet end, both of which extend into the second cabinet 201 and are connected to the cooling unit 302. A circulation path can be formed between the cooling unit 302 and the cooling pipe 301. The circulation path is filled with coolant, which can be an aqueous solution of ethylene glycol. The cooling unit 302 includes a circulation pump and a heat exchanger. The circulation pump is used to provide pressure so that the coolant can flow in the circulation path. The heat exchanger is used to exchange heat with the coolant, thereby cooling the coolant.
[0042] Understandably, the cryogenic coolant flows into the cooling pipe 301 from the inlet end under the pressure of the circulating pump and flows along the cooling pipe 301. During this process, the cryogenic coolant passes through the battery pack 102, thereby exchanging heat with the battery pack 102 and cooling the battery pack 102. The coolant that has absorbed the heat from the battery pack 102 enters the heat exchanger from the outlet end of the cooling pipe 301. The heat exchanger absorbs the heat from the coolant, thereby cooling the coolant. The cooled cryogenic coolant then enters the inlet end of the cooling pipe 301 again through the circulating pump, thus achieving circulation.
[0043] In some embodiments, the top of the first cabinet 101 is provided with a hanging lug 4.
[0044] Specifically, such as Figures 1 to 5 As shown, the lifting lug 4 can be an L-shaped structure. There are multiple lifting lugs 4, which are divided into two groups. The two groups of lifting lugs 4 are symmetrically distributed on both sides of the top of the first cabinet 101. Each lifting lug 4 is fixedly connected to the first cabinet 101 by bolts.
[0045] It is understandable that by setting lifting lugs 4 on the top of the first cabinet 101, the lifting equipment can be hung on the lifting lugs 4 when the first cabinet 101 is transferred, making it convenient to move the first cabinet 101 using external lifting equipment, thus realizing the rapid transfer of the first cabinet 101.
[0046] In some embodiments, the split-type energy storage system is further provided with a connecting block 5. When multiple first cabinets 101 are continuously distributed, the connecting block 5 can be connected to the lugs 4 of two adjacent first cabinets 101 respectively, so that the two adjacent first cabinets 101 are fixed into a whole.
[0047] Specifically, such as Figure 5 As shown, the connecting block 5 has mounting holes at both ends. When the two first cabinets 101 are continuously distributed along their width, the lifting lugs 4 on the contact side of the two first cabinets 101 are tightly attached to each other, thus forming a T-shaped structure. The connecting block 5 can be placed on the top of the T-shaped structure. The mounting holes at both ends of the connecting block 5 correspond to the mating holes on the two lifting lugs 4. The connecting block 5 is fixed to the two lifting lugs 4 by bolts, thereby fixing the two lifting lugs 4 together, thus realizing the fixation between the two first cabinets 101.
[0048] It is understandable that by fixing two adjacent first cabinets 101 together through connecting block 5, the stability of the first cabinet 101 can be improved, preventing one of the first cabinets 101 from collapsing. When transferring the first cabinet 101, multiple first cabinets 101 can be transported simultaneously, saving transportation time.
[0049] In some embodiments, the bottom of the first cabinet 101 is provided with a protrusion 6, which can support the first cabinet 101.
[0050] Specifically, such as Figure 1 As shown, the protrusion 6 can be a square tube. The protrusion 6 is fixedly installed at the bottom of the first cabinet 101. The bottom surface of the protrusion 6 is a plane. The bottom surface of the protrusion 6 can be supported on the ground or the top surface of the second cabinet 201.
[0051] Understandably, by supporting the first cabinet 101 with the protrusion 6, the bottom of the first cabinet 101 can be prevented from touching the ground or the second cabinet 201, making it easier for the forklift's steel fork to extend under the first cabinet 101, so that the first cabinet 101 can be lifted by the forklift and transported by the forklift.
[0052] In some embodiments, the first cabinet 101 is provided with a smoke sensor 7 and a temperature sensor 8.
[0053] Specifically, such as Figure 4 As shown, both the smoke sensor 7 and the temperature sensor 8 are electrically connected to the electrical component 103. The smoke sensor 7 is used to monitor whether there is smoke inside the first cabinet 101, and the temperature sensor 8 is used to monitor whether there are abnormal heat points inside the first cabinet 101.
[0054] Understandably, during normal operation of the battery compartment 1, an abnormal heat source may appear inside the first cabinet 101 due to an electrical short circuit. When the smoke sensor 7 detects the generation of smoke or the temperature sensor 8 detects an abnormal heat source, it will send a signal to the electrical component 103. The electrical component 103 can then shut down the battery compartment 1 to prevent the continuous generation of heat from causing thermal runaway.
[0055] In some embodiments, such as Figure 3 As shown, the first cabinet 101 has a first cabinet door 1011, which is rotatably engaged with the first cabinet 101. The first cabinet 101 is provided with a threshold switch 9, which can stop the first cabinet door 1011.
[0056] It is understandable that the limit switch 9 is electrically connected to the electrical component 103 via wires. When the first cabinet door 1011 is closed, the limit switch 9 is in contact with the first cabinet door 1011. When the first cabinet door 1011 is opened, the limit switch 9 is activated, thereby shutting down the battery compartment 1 and cutting off the power to the battery compartment 1, thus avoiding safety hazards for staff when opening the door for maintenance.
[0057] Preferred, such as Figure 1 As shown, the first cabinet door 1011 is also equipped with an emergency stop button 10. The emergency stop button 10 is electrically connected to the electrical component 103. By pressing the emergency stop button 10, the battery compartment 1 can be manually powered off to prevent the battery compartment 1 from remaining powered on in case of an accident, thus avoiding further expansion of safety hazards.
[0058] In some embodiments, such as Figure 3 As shown, the bottom of the first cabinet 101 is equipped with a heat insulation board.
[0059] Understandably, by setting up the heat insulation board, when the abnormal heat source in the first cabinet 101 further expands into thermal runaway, the heat insulation board can separate the first cabinet 101 and the second cabinet 201, preventing the first cabinet 101 from spreading the thermal runaway to the second cabinet 201.
[0060] In some embodiments, the bottom of the second cabinet 201 is provided with an expansion interface, which can be electrically connected to multiple battery compartments 1 via wires.
[0061] Specifically, such as Figure 6 and Figure 7 As shown, when the system needs to be expanded, there is a situation where one device compartment 2 is connected to multiple battery compartments 1. At this time, the additional battery compartments 1 can be placed next to the device compartment 2 and distributed continuously. The additional battery compartments 1 can be fixedly connected to each other through connecting blocks 5, so that the additional battery compartments 1 are fixed into a whole. The expansion interface at the bottom of the device compartment 2 can be electrically connected to the first interface at the bottom of the additional battery compartment 1 through wires, so that the additional battery compartment 1 is connected in parallel with the original battery compartment 1, thereby expanding the capacity of the energy storage system.
[0062] In summary, the split-type energy storage system of this application reduces the system's footprint and achieves high flexibility in transportation, deployment, expansion, and maintenance by physically separating and modularizing the battery compartment 1 and the device compartment 2.
[0063] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0064] The foregoing has provided a detailed description of the cracked energy storage system provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
