[0001] This invention relates to the field of battery energy storage technology, and in particular to a shock-resistant battery energy storage system adapted to the marine transportation environment. Background Technology

[0002] With the development of global trade, maritime transport is playing an increasingly important role in the export of goods. This is especially true for battery energy storage products, with more and more companies shipping them globally by sea. However, battery energy storage systems often face various challenges during long-distance maritime transport, particularly in environments requiring them to float for up to three months, where the stability of existing battery energy storage systems often fails to meet the stringent requirements.

[0003] Traditional battery energy storage systems are primarily designed for terrestrial environments, where the operating environment is relatively stable. However, the maritime transport environment is entirely different, involving factors such as severe vibration, temperature changes, and prolonged floating. Existing battery energy storage products often exhibit poor stability during maritime transport. During sea transport, ships encounter the impact of waves and rolling, generating significant vibrations. These external mechanical forces can cause impacts on the components of the battery energy storage system, especially the internal cells, connecting wires, and circuit boards, potentially leading to loosening, damage, or poor contact. This often results in battery short circuits, performance degradation, or even complete battery failure, rendering the battery energy storage system unable to function properly.

[0030] Please see Figure 1-7The present invention provides a technical solution: an impact-resistant battery energy storage system adapted to the marine transportation environment, comprising multiple battery energy storage devices and a support platform 1. The battery energy storage devices include energy storage boxes 2, and multiple battery modules 3 are disposed inside the energy storage boxes 2. Multiple protective mechanisms 4 for buffering the battery energy storage devices are disposed on the support platform 1. An adjustment mechanism 5 is disposed below the support platform 1. The adjustment mechanism 5 includes a support component 51, which is connected to the support platform 1 at the top and to a base plate 56 at the bottom. The support component 51 is circumferentially provided with a first adjustment cylinder 52, a second adjustment cylinder 53, and a third adjustment cylinder 54 hinged to the support platform 1. A measuring component 55 is disposed on the base plate 56.

[0031] In the technical solution of this invention, by setting multiple protective mechanisms 4 for buffering on the support platform 1, the vibration and impact generated during maritime transportation can be effectively absorbed, thereby reducing the risk of damage and failure of the battery energy storage device. The first adjusting cylinder 52, the second adjusting cylinder 53, and the third adjusting cylinder 54 on the adjusting mechanism 5 are connected to the support platform 1, enabling dynamic adjustment according to changes in the external environment. The measuring component 55 set on the base plate 56 can monitor the angle changes and acceleration data of the energy storage device in real time. Based on this real-time data, the extension and retraction distances of the first adjusting cylinder 52, the second adjusting cylinder 53, and the third adjusting cylinder 54 can be adjusted to ensure that the battery energy storage device is always in the optimal working state. The system can automatically adjust the position and state of the battery energy storage device, thereby maintaining the stability of the battery module and avoiding battery damage caused by excessive vibration or tilting. By combining multiple advanced technologies such as shock-resistant design, dynamic adjustment, real-time monitoring, and thermal management, the shock resistance, stability, reliability, and adaptability of the battery energy storage system during maritime transportation are significantly improved, ensuring that the battery energy storage device can maintain efficient and stable operation even in complex and harsh maritime transportation environments.

[0032] Among them, the support platform 1 serves as the system base, adopting a high-strength aluminum alloy frame with an anti-corrosion coating on the surface. It supports all battery energy storage devices. The battery energy storage device consists of an energy storage box 2 and an internal battery module 3. The modular design facilitates maintenance and replacement. The protective mechanism 4 forms a multi-level buffer structure to disperse external impact forces. The dynamic balance system is achieved through the adjustment mechanism 5, and the platform attitude is adjusted in coordination with hydraulic cylinders and sensors.

[0033] Specifically, the support assembly 51 includes a support rod 511, a rotating seat 512 rotatably connected above the support rod 511, and the rotating seat 512 connected to the support platform 1. The measuring assembly 55 includes a first tilt gyroscope 551, a first accelerometer 552, a second tilt gyroscope 553, and a second accelerometer 554. The first tilt gyroscope 551 and the first accelerometer 552 are connected above the base plate 56, and the second tilt gyroscope 553 and the second accelerometer 554 are connected below the support platform 1. The support assembly 51 is connected to the support rod 511 and the rotating seat 512. The structural design of component 2 provides flexible support and stability. The combined use of measurement components 55 enables high-precision angle and acceleration measurements. The first tilt gyroscope and accelerometer, and the second tilt gyroscope and accelerometer, are respectively positioned in different locations, which helps improve overall measurement accuracy and system stability. By placing the first tilt gyroscope 551, the first accelerometer 552, the second tilt gyroscope 553, and the second accelerometer 554 at different locations on the base plate 56 and the support platform 1, the system can simultaneously acquire data from multiple angles and positions. This design enhances the comprehensiveness of the measurement, enabling real-time monitoring and supplementation of multi-dimensional data throughout the structure, thereby improving the accuracy and completeness of the measurement.

[0034] like Figure 1 and Figure 2 As shown, the first adjusting cylinder 52, the second adjusting cylinder 53 and the third adjusting cylinder 54 are arranged in a triangular shape. The first adjusting cylinder 52, the second adjusting cylinder 53 and the third adjusting cylinder 54 are all connected to the support platform 1 and the base plate 56 by hinge. The support rod 511 is located in the middle of the first adjusting cylinder 52, the second adjusting cylinder 53 and the third adjusting cylinder 54.

[0035] like Figure 1 and Figure 3 As shown, the protective mechanism 4 includes a protective box 41. The side of the protective box 41 is connected to a buffer plate 44 via a first buffer spring 42 and a first spring damper 43. The buffer plate 44 is in close contact with the energy storage box 2. The connection between the protective box 41 and the buffer plate 44 via the first buffer spring 42 and the first spring damper 43 effectively absorbs and mitigates the impact energy from ocean waves. These buffer components effectively reduce the impact of ocean waves on the energy storage box 2, ensuring the safety of the energy storage device in a severe ocean wave environment. The buffer plate 44 is made of rubber-metal composite material, which has strong elasticity and impact resistance, and can more efficiently convert the kinetic energy of ocean wave impact into elastic deformation, thereby reducing the impact force. The connection between the protective box 41 and the buffer plate 44 ensures the stability of the protective system. Through the close contact between the buffer plate 44 and the side wall of the energy storage box, the direct impact from ocean waves can be effectively reduced, preventing the energy storage box from tilting or being damaged due to external impact. At the same time, the multi-partition design and buffer block configuration inside the protective box enable the entire system to better maintain a stable state when facing complex external environments.

[0036] Specifically, the protective box 41 has multiple partitions 45 inside, and buffer blocks 46 are installed on the partitions 45. The buffer blocks 46 are connected to the inner wall of the protective box 41 through second buffer springs 47 and second spring dampers 48. Rollers 49 are installed below the buffer blocks 46. The protective box 41 has multiple partitions 45 inside, with buffer blocks 46 on each partition. The buffer blocks 46 are connected to the inner wall of the protective box through second buffer springs 47 and second spring dampers 48, forming a multi-layered buffering mechanism. This multi-layered buffering structure allows the impact energy of each part to be gradually dispersed and absorbed, thereby effectively reducing the impact load on the system and improving the protective effect. The second buffer springs 47 and second spring dampers 48 allow the response of each buffer block 46 to be adjusted according to different impact conditions. This adjustability enhances the system's adaptability, allowing it to adjust according to the intensity and frequency of waves, ensuring optimal buffering performance in different environments. The rollers 49 below the buffer blocks 46 help reduce friction during repeated movement, reducing wear on the equipment. The partition plate 45 and the buffer block 46 effectively disperse the impact force from the waves, ensuring that each buffer block only withstands a portion of the impact, rather than concentrating the impact force on a single part. This helps reduce the stress on individual components, enhances the protective effect, and ensures the safety of the energy storage tank 2 within the entire protection system.

[0037] like Figure 4 and Figure 7 As shown, a horizontal heat-conducting plate 15 and a vertical heat-conducting plate 16 are embedded between adjacent battery modules 3. The end of the horizontal heat-conducting plate 15 is connected to the vertical heat-conducting plate 16. A cover plate 17 located directly above the vertical heat-conducting plate 16 is detachably connected to the energy storage box 2. The vertical heat-conducting plate 16 is connected to the heat exchange plate 18, and the heat exchange plate 18 is connected to the heat exchange pipe 19. The horizontal heat-conducting plate 15 and the vertical heat-conducting plate 16 effectively conduct the heat generated by the battery module 3 from the battery module to the outside of the energy storage box through their good thermal conductivity, thereby keeping the battery temperature within a suitable range. The design of the heat-conducting plate can greatly improve the heat dissipation efficiency of the system, prevent the battery from overheating, and extend the battery life. Through the connection between the vertical heat-conducting plate 16 and the heat exchange plate 18 and the heat exchange pipe 19, the heat can be continuously and effectively conducted to the external heat dissipation system. The detachable design of the cover plate 17 makes it easy to maintain or replace the heat conduction system when needed, improving the maintainability of the system.

[0038] The heat exchange plate 18 is connected to the titanium alloy heat exchange tube 19, which pumps coolant to the corrugated heat dissipation fins on the outer wall of the ship. Forced convection heat exchange is achieved by utilizing seawater flow. The coolant pump speed is dynamically adjusted by a PID algorithm based on the battery temperature and seawater flow rate. The seawater contact area is optimized by combining the angle of the guide plate. The surface of the heat dissipation fins is coated with an Ag / TiO2 nano-coating to inhibit biofouling. The built-in piezoelectric ceramic plate periodically generates ultrasonic waves to remove deposits.

[0039] Specifically, the battery electrode materials are optimized. The positive electrode uses a LiNi0.8Co0.1Mn0.1O2 surface coated with a Li3VO4 fast ion conductor layer to reduce interfacial impedance. The negative electrode uses silicon-carbon composite particles embedded in a three-dimensional copper nanowire current collector to alleviate volume expansion. Low temperature mode (T<10℃): The PTC heating film (integrated into the battery casing) is activated, and the BMS switches to a pulse heating strategy to raise the battery temperature to above 15℃. High temperature mode (T>40℃): The liquid cooling system is activated to limit the charging current to below 0.3C, and the internal resistance is monitored online via EIS to dynamically adjust the SOC window.

[0040] like Figure 5 and Figure 6 As shown, adjacent battery modules 3 are connected by mounting plates 6. Limiting plates 7 are provided on both sides of the battery modules 3, and multiple reinforcing plates 8 are connected between the limiting plates 7. Fastening plates 9 are provided on the sides of the limiting plates 7, and clamping plates 10 are provided on the fastening plates 9. The mounting plates 6 connect adjacent battery modules 3, effectively preventing displacement of the battery modules due to vibration or external forces during transportation. The use of mounting plates 6 ensures the stable fixation of the battery modules within the energy storage box, reducing the risk of mutual friction between battery modules and preventing battery damage or malfunction. The limiting plates 7 provide clear positioning for the battery modules, and the reinforcing plates 8 further enhance the structural robustness. The limiting plates and reinforcing plates work together to effectively prevent collisions between battery modules and reduce mechanical impact damage to the batteries. The design of the fastening plates 9 and clamping plates 10 not only reinforces the battery modules but also disperses external impact forces to a certain extent, mitigating the impact of vibration on the battery energy storage system. Especially during transportation, when encountering strong vibrations or external forces, the fastening plate design can effectively alleviate such impacts.

[0041] The fastening plate 9 has a limiting protrusion 12 below it and a slot 11 on it. The limiting plate 7 has a limiting slot 13 that matches the limiting protrusion 12. The fastening plate 9 is connected to the energy storage box 2 by bolts 14. The fastening plate 9 on the side of the limiting plate 7 is tightly connected to the battery module by a clamping plate 10 to ensure the fixation of the limiting plate. The cooperation between the limiting slot 13 and the limiting protrusion 12 on the fastening plate 9 makes the structure more robust and can prevent the limiting plate 7 from shifting or falling off during transportation, thereby ensuring that the battery module is always in the correct position throughout the process. The fastening plate 9 is firmly connected to the energy storage box 2 by bolts 14. The structure of the entire battery energy storage device is more stable and can effectively withstand the impact from the outside, and enhance the system's shock resistance. Especially in complex and harsh transportation environments, the battery energy storage system can maintain good safety and reliability. The slotted design 11 makes it easier for the fastening plate 9 to cooperate with the limiting plate 7. At the same time, it is also easy to disassemble and repair when needed. This design not only improves the convenience of installation, but also reduces the complexity of maintenance and improves the maintainability of the system.

[0042] like Figure 1 and Figure 4 As shown, an upper positioning plate 20 is provided on the top of the energy storage box 2, and a lower positioning plate 21 is provided on the bottom of the energy storage box 2; the upper positioning plate 20 and the lower positioning plate 21 can be assembled and limited, so that multiple energy storage boxes 2 can be stably fixed on the support platform 1.

[0043] Working Principle: By setting multiple buffering protective mechanisms 4 on the support platform 1, the vibration and impact generated during maritime transportation can be effectively absorbed, thereby reducing the risk of damage and failure of the battery energy storage device. The first adjusting cylinder 52, the second adjusting cylinder 53, and the third adjusting cylinder 54 on the adjusting mechanism 5 are connected to the support platform 1, enabling dynamic adjustment according to changes in the external environment. The measuring component 55 on the base plate 56 can monitor the angle changes and acceleration data of the energy storage device in real time. Based on this real-time data, the extension and retraction distances of the first adjusting cylinder 52, the second adjusting cylinder 53, and the third adjusting cylinder 54 can be adjusted to ensure that the battery energy storage device is always in optimal working condition. The system can automatically adjust the position and state of the battery energy storage device, thereby maintaining the stability of the battery module and avoiding battery damage caused by excessive vibration or tilting.
