Description

Technical Field

[0001] This utility model relates to the field of energy storage, specifically a prefabricated cabin-type energy storage system. Background Technology

[0002] In today's energy sector, with the ever-increasing demand for clean energy and the large-scale development and utilization of renewable energy, the importance of energy storage technology is becoming increasingly prominent. Prefabricated modular energy storage systems, as an innovative energy storage solution, have emerged to meet this need.

[0003] On the one hand, with rapid socio-economic development, energy consumption continues to increase, and traditional energy sources face increasingly severe supply pressures and environmental challenges. While renewable energy sources such as solar and wind power have the advantages of being clean and sustainable, their intermittency and instability pose challenges to the stable operation of the power system. Energy storage systems, on the other hand, can store energy when renewable energy generation is in surplus and release it during peak electricity demand or when renewable energy generation is insufficient, playing a crucial role in balancing supply and demand and improving energy efficiency. On the other hand, traditional energy storage systems often have many limitations in their layout. For example, the equipment is dispersed, occupying a large space and hindering centralized management and maintenance. Furthermore, traditional energy storage systems have poor scalability, making it difficult to flexibly adjust storage capacity and power output according to actual needs. In terms of maintenance, due to their complex structure, troubleshooting and repair are difficult, not only consuming significant time and manpower costs but also potentially affecting the normal operation of the entire power system.

[0004] Prefabricated modular energy storage systems effectively solve these problems. They integrate the battery compartment and control room into a single prefabricated compartment, achieving efficient space utilization through rational partitioning and layout. Simultaneously, the modular design provides excellent scalability, allowing for flexible configuration to meet diverse energy storage needs. In terms of maintenance, each module is relatively independent; in the event of a fault, the faulty module can be quickly located and replaced individually without affecting the overall system operation, significantly reducing maintenance costs and time.

[0005] Prefabricated modular energy storage systems offer a unique advantage and provide an effective way to solve many of the current problems facing the energy sector, with broad development prospects. Utility Model Content

[0006] The purpose of this invention is to provide a prefabricated cabin-type energy storage system, which, by dividing the space into a battery room and a control room, achieves a clear division of functions, facilitating targeted management and maintenance of different functional areas, thereby solving the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A prefabricated cabin-type energy storage system includes a prefabricated cabin body, characterized in that the interior of the prefabricated cabin body is divided into a battery compartment and a control compartment, separating the battery part from the control part. On the one hand, this can improve the safety of the system and avoid the impact of potential battery problems on the control equipment; on the other hand, it also facilitates targeted management and maintenance of different functional areas.

[0009] The battery compartment is divided on both sides by perforated partitions, with a central airflow channel. Battery modules are fitted into the perforated partitions on one side, and each battery module is equipped with a standardized interface. The perforated partitions serve to secure the battery modules without completely obstructing airflow. This design ensures structural stability while achieving good ventilation and heat dissipation. The central airflow channel provides a dedicated path for air movement, further enhancing heat dissipation efficiency.

[0010] Standardized interfaces enable battery modules to have better versatility and interchangeability. In practical applications, battery modules can be quickly replaced or expanded according to different needs, improving the system's flexibility and adaptability.

[0011] Each battery module is connected to a corresponding battery management system, which is arranged between the hollow partitions on opposite sides of the battery modules.

[0012] The battery management system (BMS) is responsible for monitoring and managing the status of each battery module. Its placement within a perforated partition opposite the battery modules facilitates easy connection to the modules and also allows for convenient maintenance and management. By monitoring battery status in real time, the BMS can promptly identify problems and take appropriate measures to ensure the safe operation of the battery modules.

[0013] The battery module circuit is connected to an energy conversion system located in the control room. The energy conversion system is modularly divided and includes a power module, a control module, and a communication module. The modules are connected to each other through a high-speed communication interface.

[0014] The energy conversion system is responsible for converting the direct current (DC) output from the battery module into alternating current (AC) or other forms of electrical energy to meet different power demands. Modular design allows each module to operate independently, improving system reliability and maintainability. If a module fails, it can be replaced individually without affecting the normal operation of other modules. High-speed communication interfaces ensure rapid data transmission and collaborative operation between modules, enhancing overall system performance.

[0015] The prefabricated cabin is equipped with an intake fan and an exhaust fan on both sides, which correspond to the air passage left in the middle of the prefabricated cabin.

[0016] The intake and exhaust fans work together to create airflow, which dissipates heat from the battery compartment through the air duct. The intake fan draws in cool outside air into the prefabricated compartment. The cool air passes through the battery modules and other equipment, absorbs heat, and becomes hot air. Then, the exhaust fan discharges the air from the prefabricated compartment, thus effectively dissipating heat from the battery compartment and ensuring the stable operation of the system.

[0017] The battery management system is connected to the control module, and the battery management system transmits battery status information to the control module to adjust the output power and operating mode in real time.

[0018] Through data connectivity, the control module can acquire real-time battery status information monitored by the battery management system. Based on this information, the control module can adjust the output power and operating mode of the energy conversion system in real time to achieve optimized control of the energy storage system. When the battery charge is low, the output power can be reduced to extend the battery's lifespan; when the power demand is high, the output power can be increased to meet the load requirements.

[0019] The battery modules are all equipped with standardized interfaces to change the connection mode according to different energy storage needs; the connection modes include high-energy mode and high-power mode. The high-energy mode connects multiple battery modules in parallel to increase capacity; the high-power mode connects battery modules in series to increase voltage.

[0020] The high-energy mode is suitable for applications requiring large energy storage capacity. By connecting multiple battery modules in parallel, the total system capacity can be increased to meet long-term energy storage needs. The high-power mode is suitable for applications requiring high output power. By connecting battery modules in series, the system's output voltage can be increased, thereby increasing the output power. This flexible connection mode allows the prefabricated capsule energy storage system to be adjusted according to different application scenarios, improving the system's adaptability and practicality.

[0021] Each module of the energy conversion system can operate independently, while simultaneously collaborating via a high-speed communication interface. If a single module fails, it can be replaced individually without affecting the operation of the entire system. The independent operation of each module means that even if one module fails, the others can continue to function, ensuring that some system functions remain unaffected. Furthermore, the collaborative operation via the high-speed communication interface enables efficient operation of the entire energy conversion system. When a single module fails, it can be quickly located and replaced individually, eliminating the need for large-scale system-wide repairs, significantly reducing maintenance time and costs.

[0022] The communication module of the energy conversion system is connected to a cloud server, which has control functions. The local controller inside the prefabricated cabin also has control functions. The cloud server enables the coordinated operation of large-scale energy storage systems by centrally managing and optimizing the scheduling of multiple prefabricated cabin energy storage systems.

[0023] The communication module connects the prefabricated energy storage system to a cloud server, enabling the cloud server to obtain real-time system operating status information and remotely control and manage the system. The cloud server possesses powerful computing and analytical capabilities, allowing for centralized management and optimized scheduling of multiple prefabricated energy storage systems. This enables collaborative operation of large-scale energy storage systems, improving energy utilization efficiency and system stability.

[0024] The local controller is responsible for real-time monitoring and control of the local equipment's operating status, while also communicating with the cloud server to receive instructions and data from the cloud. In the event of a network outage or a cloud server failure, the local controller can operate independently, ensuring that the basic functions of the prefabricated energy storage system remain unaffected. The local controller and the cloud server work together to achieve efficient management and control of the energy storage system.

[0025] A charging / discharging interface is provided on the battery compartment side, and the charging / discharging interface is connected to the battery module circuit.

[0026] A charging / discharging interface is located on the battery compartment side for easy connection to an external power source or load, enabling the charging and discharging functions of the battery module. Positioning the charging / discharging interface on the battery compartment side allows for direct circuit connection to the battery module, reducing line losses and improving charging / discharging efficiency.

[0027] The battery modules are installed between perforated partitions on one side of the battery compartment. Each module is equipped with a standardized interface, allowing for interchangeable connection modes to meet different energy storage needs. In high-energy mode, multiple battery modules are connected in parallel to increase system capacity and meet long-term energy storage requirements. In high-power mode, battery modules are connected in series to increase voltage, thereby outputting higher power, suitable for applications with high power demands. Each battery module is connected to a corresponding battery management system (BMS). The BMS is located between the perforated partitions on the opposite side of the battery modules, monitoring the battery module status in real time. During charging and discharging, the BMS closely monitors changes in these parameters. Simultaneously, the BMS transmits battery status information to the control module, providing data support for the optimized operation of the entire system.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] By dividing the interior of the prefabricated cabin into a battery compartment and a control compartment, a clear functional division is achieved. The battery compartment houses the battery modules and related equipment, while the control compartment is used to house the energy conversion system and control equipment. This layout not only improves system safety and prevents potential battery problems from affecting the control equipment, but also facilitates targeted management and maintenance of different functional areas.

[0030] The battery compartment features perforated partitions on both sides and an air duct in the center. Intake and exhaust fans are installed on both sides of the prefabricated compartment, forming an effective heat dissipation system. The intake fans draw in cool outside air, which absorbs heat as it passes through the battery modules and other equipment before being exhausted by the exhaust fans, effectively reducing the equipment's operating temperature. This helps ensure the safe operation of the battery modules and other electronic equipment, extends the equipment's lifespan, and reduces the risk of failure due to overheating.

[0031] The battery modules are equipped with standardized interfaces, allowing for interchangeable connection modes to meet different energy storage needs. In high-energy mode, multiple battery modules can be connected in parallel to increase capacity and meet long-term energy storage requirements; in high-power mode, battery modules can be connected in series to increase voltage and adapt to high-power output applications. This flexibility enables the energy storage system to be widely used in various scenarios, such as industrial production, commercial power supply, and home energy storage, improving the system's adaptability and practicality.

[0032] The energy conversion system employs a modular design, comprising power modules, control modules, and communication modules, which are connected via high-speed communication interfaces. Each module can operate independently or collaboratively. If a single module fails, it can be replaced without affecting the operation of the entire energy conversion system. This significantly improves system reliability and maintainability, reducing maintenance costs and time. Furthermore, the modular design facilitates system upgrades and expansion, enabling continuous performance improvements as technology advances.

[0033] The communication module connects to a cloud server, which has control functions and can centrally manage and optimize the scheduling of multiple prefabricated energy storage systems, enabling the coordinated operation of large-scale energy storage systems. The local controller is responsible for real-time monitoring and control of the local equipment's operating status. In the event of a network outage or a cloud server failure, the local controller can operate independently. This dual cloud and local control approach ensures stable system operation under various conditions, improving system reliability and adaptability. Attached Figure Description

The modules are connected to each other through a high-speed communication interface.

[0040] The prefabricated cabin is equipped with an inlet fan 41 and an outlet fan 42 on both sides, respectively, and the inlet fan 41 and the outlet fan 42 correspond to the air passage left in the middle of the prefabricated cabin.

[0041] The battery management system 2 is connected to the control module 32, and the battery management system 2 transmits battery status information to the control module 32 to adjust the output power and working mode in real time.

[0042] Each battery module 1 is equipped with a standardized interface to change the connection mode according to different energy storage needs; the connection mode includes a high-energy mode and a high-power mode. The high-energy mode connects multiple battery modules 1 in parallel to increase capacity; the high-power mode connects battery modules 1 in series to increase voltage.

[0043] Each module of the energy conversion system 3 can work independently, while working together through a high-speed communication interface. When a single module fails, it can be replaced individually without affecting the operation of the entire energy conversion system 3.

[0044] The communication module 33 of the energy conversion system 3 is connected to the cloud server 5. The cloud server 5 has control functions, and the local controller 6 in the prefabricated cabin also has control functions. The cloud server 5 realizes the coordinated operation of large-scale energy storage systems by centrally managing and optimizing the scheduling of multiple prefabricated cabin energy storage systems.

[0045] The local controller 6 is responsible for real-time monitoring and control of the operating status of local devices, and communicates with the cloud server 5 to receive instructions and data from the cloud. The local controller can operate independently when the network is interrupted or the cloud server fails.

[0046] The control room is equipped with a personnel entrance and exit.

[0047] A charging / discharging interface is provided on the side of the battery compartment, and the charging / discharging interface is connected to the circuit of the battery module 1.

[0048] In implementing this prefabricated cabin-type energy storage system, the first step is to construct a prefabricated cabin and divide its interior into a battery compartment and a control compartment. Perforated partitions are installed on both sides of the battery compartment, leaving a ventilation channel in the middle. Battery modules 1 equipped with standardized interfaces are then inserted between the perforated partitions on one side. A battery management system 2 is arranged between the perforated partitions on the opposite side, with each battery module 1 connected to the corresponding battery management system 2. The battery modules 1 are connected via circuitry to the energy conversion system 3 in the control compartment. This system is modularly divided into a power module 31, a control module 32, and a communication module 33, with modules connected via high-speed communication interfaces.

The battery management system 2 connects to the control module 32, transmitting battery status information for real-time adjustment of output power and operating mode. The battery modules 1 can change their connection mode according to different energy storage needs: high-energy mode uses parallel connection to increase capacity, and high-power mode uses series connection to increase voltage. The communication module 33 of the energy conversion system 3 is connected to the cloud server 5. A local controller 6 is also located within the prefabricated cabin. Both can be controlled. The cloud server 5 can centrally manage and optimize the scheduling of multiple prefabricated cabin energy storage systems, while the local controller 6 can operate independently in case of network interruption or cloud server 5 failure. The control room side is equipped with personnel entrances and exits, while the battery room side is equipped with charging and discharging interfaces connected to the battery module 1 circuitry.
