Description

Technical Field

[0001] This invention relates to the field of integrated energy storage and charging power equipment, and in particular to a mobile integrated energy storage and charging power equipment and its control system. Background Technology

[0002] Mobile integrated energy storage and charging power equipment is a mobile energy solution that integrates energy storage systems and charging functions within a standard industrial container. It adopts a modular design, internally containing core components such as an energy storage battery system, a power converter (PCS), a DC charging pile, a battery management system (BMS), and an energy management system (EMS). This equipment can achieve peak shaving and valley filling, charging and storing energy during off-peak hours and discharging to power electric vehicles and other equipment during peak hours, effectively alleviating grid pressure. It features rapid deployment (operation in as little as 72 hours), strong environmental adaptability (operating temperature range -40℃~55℃), and high protection rating (IP54 / IP55). It is mainly used in various scenarios such as temporary power supply sites, emergency rescue, peak shaving at new energy power plants, and fast charging of electric vehicles. It can be used in fixed installations or moved and dispatched via trailers, providing flexible power services.

[0003] To address the application of the above technologies, prior art publication number CN121749282A discloses a mobile solid thermal storage and battery-assisted islanded integrated energy system. This system includes a thermal storage heat exchange unit, a heat exchange fan, an insulation layer, an energy storage battery, a fast power outlet, an instrument cabinet, a water circulation system, a hot water pump, and an inverter. The insulation layer wraps around the thermal storage heat exchange unit. The heat exchange fan and hot water pump are connected to the thermal storage heat exchange unit. The water circulation system forms a closed loop with the thermal storage heat exchange unit and the hot water pump. The energy storage battery is electrically connected to the inverter, the fast power socket is electrically connected to the inverter, and the instrument cabinet is electrically connected to the thermal storage heat exchange unit, heat exchange fan, energy storage battery, heat exchange water pump, and inverter respectively. It is used to monitor and control the operating status of each component. The system adopts a modular and containerized design, which has the characteristics of rapid deployment, mobility and scalability. It can be flexibly transported to a designated location according to the energy needs of isolated scenarios, and is suitable for remote areas, emergency disaster relief, and temporary or mobile energy use scenarios in field operations, without the need for complex infrastructure investment.

[0004] After studying the above-mentioned existing technologies and other existing technologies, their shortcomings were found: such integrated storage and charging equipment usually covers the battery surface with heat-conducting pipes or other auxiliary heat-conducting devices to solve the heat dissipation problem. Although this method can achieve a good heat distribution effect, due to the limitations of the container itself, although heat dissipation ducts can be opened on the side of the container, relying solely on natural flow channels cannot achieve sufficient heat exchange with the outside cold air. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] This invention provides a mobile integrated energy storage and charging device and its control system, which can solve the problem of insufficient heat dissipation caused by relying on the airflow channel of the energy storage box for heat dissipation in the prior art. The specific solution is as follows: On one hand, the present invention provides a mobile integrated energy storage and charging power device, including an energy storage box, several batteries installed inside the energy storage box, and at least one charging device. The batteries are stacked in multiple layers inside the energy storage box, and each layer of batteries is supported by a support plate. The support plate has several mounting slots arranged laterally, and two symmetrical batteries are installed in each mounting slot longitudinally, with the terminals of the two batteries facing outwards. Several heat-conducting strips are connected to the bottom of each support plate, and each heat-conducting strip is S-shaped and roughly covers the top projection surface of the mounting slot. The heat-conducting strips protrude from the bottom surface of the support plate. The bottom of the heat-conducting strip on the upper support plate contacts the top of the battery on the lower support plate, forming a heat dissipation gap between the bottom of the upper support plate and the top of the lower battery. The heat-conducting strip has a heat-conducting cavity inside, which is filled with coolant. The two ends of the heat-conducting cavity extend to one end of the support plate. The heat-conducting cavities under the mounting slots on several support plates are connected in sequence. The beginning and end parts of the heat-conducting cavities on several support plates are connected by a circulation pipe. A circulation pump is installed in the middle of the circulation pipe. The circulation pump drives the coolant inside the heat-conducting cavity to flow, dispersing the heat of each battery.

[0007] Preferably, a heat dissipation pipe is also installed in the middle of the circulation pipe. The heat dissipation pipe is located between the top of the uppermost battery and the top of the inner wall of the energy storage box. The heat dissipation pipe is S-shaped. A fan is installed on the top of the energy storage box, and the fan blows air towards the heat dissipation pipe.

[0008] Preferably, the top of the energy storage box is provided with a heat dissipation window, and the fan is installed on the heat dissipation window. One end of the heat dissipation window is hinged to the top of the energy storage box, and sealing sleeves are fixed to both ends of the heat dissipation window. A sealing column is slidably connected inside the sealing sleeve. The bottom of the sealing column is fixed to the top of the energy storage box, and a through hole is opened in the middle of the sealing column. The through hole is connected to an external pressure device to apply pressure to the inside of the sealing sleeve, so that the sealing sleeve moves relative to the sealing column, thereby driving the heat dissipation window to open and close. When the heat dissipation window is open, several fans form an angle with the top battery and heat dissipation pipe. The air blown out by the fans passes through the heat dissipation pipe and then bounces continuously between the top battery and the heat dissipation window, and finally blows out from the opening of the heat dissipation window.

[0009] Preferably, the heat-conducting cavities on each support plate are connected end to end by a first connecting pipe, and the heat-conducting cavities at the far ends of two adjacent support plates are connected end to end by a second connecting pipe. The heat-conducting cavities on the support plates are S-shaped along the orthogonal projection direction of the energy storage box.

[0010] Preferably, a limiting strip is fixed to the inner wall of the mounting slot, and limiting grooves matching the limiting strip are opened on both sides of the battery. The limiting grooves are slidably connected to the limiting strip, so that several batteries can be installed at the same height in the mounting slot.

[0011] Preferably, each mounting slot has several connecting slots inside, which connect the upper and lower parts of the support plate and avoid the heat conduction cavity.

[0012] Preferably, heat dissipation fins are fixed to the surfaces of the first connecting pipe, the second connecting pipe, and the heat dissipation pipe. The heat dissipation fins increase the heat exchange area, allowing the heat of the coolant inside to be quickly exchanged with the cold air.

[0013] Preferably, a sandwich layer is provided in the middle of the heat dissipation window, the fan is installed below the sandwich layer, an air inlet is provided at one end of the sandwich layer near the hinge axis of the heat dissipation window, and a waterproof slope is provided below the air inlet. When the heat dissipation window is open or closed, the waterproof slope is inclined outward.

[0014] Preferably, one end of the energy storage box has a movable door, and a movable window is hinged to the bottom of the movable door. The charging equipment is installed inside the movable door and includes a controller, a main unit, and a charging gun.

[0015] On the other hand, the present invention provides a mobile integrated power storage and charging control system, including a main control module for coordinating and controlling the operation of the entire system; The heat dissipation control module is electrically connected to the circulating pump in the heat conduction cooling system. It is used to control the start, stop and operating power of the circulating pump according to the battery temperature information, and drive the coolant to circulate in the heat conduction cavity. The charge / discharge management module is electrically connected to each battery and charging device to monitor the charge / discharge status, voltage, and current of the battery, and to control the output of the charging device. The thermal management strategy module is connected to the main control module, the heat dissipation control module and the charge and discharge management module. It is used to dynamically formulate and execute heat dissipation strategies and charge and discharge power strategies based on the battery's charge and discharge status, temperature distribution and ambient temperature. The main control module, heat dissipation control module, charge and discharge management module, and thermal management strategy module are all integrated in the control box, which is installed inside the energy storage box.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. This invention completely changes the passive heat dissipation mode that relies solely on natural airflow by using a composite heat dissipation system that combines coolant circulation driven by a circulating pump with forced ventilation by a fan. The coolant flows in the heat conduction cavity, actively collecting and transferring heat from each battery layer. Then, forced heat exchange is carried out through heat pipes and a fan to efficiently expel the heat from the energy storage tank. This active thermal management can dynamically adjust the heat dissipation intensity according to the internal temperature, ensuring excellent heat dissipation performance under high load or high temperature environments and effectively preventing heat accumulation.

[0017] 2. This invention achieves initial heat collection by directly contacting the battery with a heat-conducting strip. The S-shaped interconnected heat-conducting cavity network connects and evens out the heat from all batteries, preventing localized overheating. The heat is ultimately concentrated in the top heat dissipation pipe for centralized cooling. This hierarchical heat conduction mode ensures that the heat from each battery in the stack is effectively incorporated into the management cycle, improving overall thermal balance and extending battery life.

[0018] 3. This invention forms a highly efficient directional exhaust air duct through an openable heat dissipation window and an inclined fan linked to it. The inclined fan blows air, causing the airflow to bounce multiple times between the top of the uppermost battery and the heat dissipation window after impacting the heat dissipation pipe, and finally being discharged directionally from the heat dissipation window opening. This design forces hot air to flow rapidly along a preset path, which greatly improves the heat exchange efficiency between the airflow and the heat source, and effectively prevents hot air from stagnating and flowing back inside the box, thus achieving rapid forced heat dissipation.

[0019] 4. This invention optimizes the internal space and airflow organization, improving overall heat dissipation efficiency. By opening connecting slots on the support plate, vertical air channels between layers are created while ensuring structural strength. This not only facilitates natural air convection and assists in the upward transfer of heat, but also combines with the forced air duct at the top to form a coordinated airflow organization of "bottom in and top out". Combined with the neat and limited installation of the battery, it ensures that the internal space is regular and the airflow path is unobstructed, so that the active heat dissipation system and passive air circulation complement each other and comprehensively improve the heat dissipation effect.

[0020] 5. This invention, through the design of a sandwich structure with heat dissipation windows, a waterproof slope, and a stepped design, achieves efficient heat dissipation while providing excellent rain and water resistance, ensuring equipment safety in complex outdoor environments. Key heat dissipation components such as the heat conduction cavity and circulation pipes are internally mounted or protected, reducing the risk of external damage. The entire heat dissipation system has a high degree of integration and stable operation, significantly improving the reliability and environmental adaptability of energy storage power equipment under long-term, high-power conditions.

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a mobile integrated power storage and charging device, including an energy storage box 1, a plurality of batteries 2 installed inside the energy storage box 1, and at least one charging device 3. The plurality of batteries 2 are stacked in multiple layers inside the energy storage box 1, and each layer of batteries 2 is supported by a support plate 4.

[0026] like Figure 4 As shown, the support plate 4 has several mounting slots 5 arranged horizontally along the energy storage box 1. Each mounting slot 5 has two symmetrical batteries 2 installed vertically, with the terminals of the two batteries 2 facing outwards.

[0027] like Figure 5 As shown, each support plate 4 has several heat-conducting strips 6 connected to its bottom. Each heat-conducting strip 6 is S-shaped and roughly covers the top projection surface of the mounting groove 5. It should be noted that the coverage area can be 30% to 80% of the top projection surface of the mounting groove 5.

[0028] like Figure 6 As shown, the heat-conducting strip 6 protrudes from the bottom surface of the support plate 4. The bottom of the heat-conducting strip 6 on the upper support plate 4 contacts the top of the battery 2 on the lower support plate 4, so that the bottom of the upper support plate 4 and the top of the lower battery 2 form a heat dissipation gap 7. The heat-conducting strip 6 has a heat-conducting cavity 8 inside, which is filled with coolant. Both ends of the heat-conducting cavity 8 extend to one end of the support plate 4. The heat-conducting cavities 8 below several mounting slots 5 on several support plates 4 are connected in sequence.

[0029] like Figure 7 As shown, the beginning and end parts of the heat conduction cavities 8 on several carrier plates 4 are connected by circulation pipes 9. A circulation pump 10 is installed in the middle section of the circulation pipe 9. The circulation pump 10 drives the coolant inside the heat conduction cavity 8 to flow and disperse the heat of each battery 2.

[0030] A heat dissipation pipe 11 is also installed in the middle of the circulation pipe 9. The heat dissipation pipe 11 is located between the top of the uppermost battery 2 and the top of the inner wall of the energy storage box 1. The heat dissipation pipe 11 is S-shaped. A fan 12 is installed on the top of the energy storage box 1. The fan 12 blows air towards the heat dissipation pipe 11, thereby removing the heat from the heat dissipation pipe 11.

[0031] like Figure 8As shown, the top of the energy storage box 1 is provided with a heat dissipation window 13, and the fan 12 is mounted on the heat dissipation window 13. One end of the heat dissipation window 13 is hinged to the top of the energy storage box 1, and sealing sleeves 14 are fixedly connected to both ends of the heat dissipation window 13. A sealing column 15 is slidably connected inside the sealing sleeve 14. The bottom of the sealing column 15 is fixedly connected to the top of the energy storage box 1, and a through hole (not shown in the figure) is opened in the middle of the sealing column 15. The through hole is connected to an external pressure device, which can be a hydraulic pump or an air pump, to apply pressure to the inside of the sealing sleeve 14, so that the sealing sleeve 14 moves relative to the sealing column 15, thereby driving the heat dissipation window 13 to open and close. When the heat dissipation window 13 is open, several fans 12 form an angle with the uppermost battery 2 and the heat dissipation pipe 11. The air blown out by the fans 12 passes through the heat dissipation pipe 11 and then bounces continuously between the uppermost battery 2 and the heat dissipation window 13 (e.g., Figure 3 As shown by the arrow, the air is finally blown out from the opening of the heat dissipation window 13, thereby achieving the purpose of rapid heat dissipation. Compared with the natural airflow cooling of the existing technology, by setting an openable heat dissipation window 13, the fan 12 is tilted as a whole, so that the hot air is blown out from the opening of the heat dissipation window 13 after rebounding, thus avoiding the continuous accumulation of heat inside the energy storage box 1.

[0032] like Figure 5 As shown, several heat-conducting cavities 8 on each support plate 4 are connected end to end by a first connecting pipe 16, and the heat-conducting cavities 8 at the very end of two adjacent support plates 4 are connected end to end by a second connecting pipe 17. The heat-conducting cavities 8 on several support plates 4, the first connecting pipe 16 and the second connecting pipe 17 are S-shaped along the orthogonal projection direction of the energy storage box 1, so that the coolant inside the heat-conducting cavity 8 can complete the end-to-end circulation under the drive of the circulation pump 10.

[0033] like Figure 6 As shown, a limiting strip 18 is fixedly connected to the inner wall of the mounting groove 5, and limiting grooves 19 matching the limiting strip 18 are provided on both sides of the battery 2. The limiting grooves 19 and the limiting strip 18 are slidably connected, so that several batteries 2 can maintain the same height when installed in the mounting groove 5.

[0034] Each mounting slot 5 has several connecting slots 20 inside, which connect the support plate 4 vertically and avoid the heat conduction cavity 8.

[0035] The through-slot 20 allows air to circulate between each load-bearing plate 4, thereby increasing the heat transfer efficiency. Since heat is transferred from low to high, the heat can eventually be discharged from the heat dissipation window 13.

[0036] like Figure 9As shown, heat dissipation fins 21 are fixed to the surfaces of the first connecting pipe 16, the second connecting pipe 17 and the heat dissipation pipe 11 (taking the first connecting pipe 16 as an example in the figure). The heat dissipation fins 21 are used to increase the heat exchange area between the first connecting pipe 16, the second connecting pipe 17 and the heat dissipation pipe 11 and the cold air, so that the heat of the coolant inside them can be quickly exchanged with the cold air.

[0037] like Figure 10 As shown, in order to achieve air intake, a sandwich layer 22 is provided in the middle of the heat dissipation window 13. The fan 12 is installed below the sandwich layer 22, specifically fixedly connected to the bottom of the heat dissipation window 13, so that the top of the fan 12 is connected to the sandwich layer 22, thereby achieving the purpose of air intake. An air inlet 23 is provided at one end of the sandwich layer 22 near the hinge shaft 25 of the heat dissipation window 13. A waterproof slope 24 is provided below the air inlet 23. When the heat dissipation window 13 is open or closed, the waterproof slope 24 is inclined outward, and there is a step 26 at the root of the waterproof slope 24, so that external water cannot enter the sandwich layer 22, thereby achieving a good waterproof purpose.

[0038] It should be noted that in the above scheme, when it rains, the heat dissipation window 13 can be closed. At this time, the fan 12 is reversed to the external exhaust state, so that the heat inside the energy storage box 1 is discharged through the interlayer 22 and the air inlet 23 (in this state: the air inlet 23 is actually the air outlet), thereby achieving the purpose of heat dissipation.

[0039] It should also be noted that, in order to achieve better air intake and exhaust efficiency, technicians can make adaptive adjustments to the thickness of the heat dissipation window 13 and the width of the interlayer 22 according to actual needs. It is not a thin structure as shown in the figure. Furthermore, there can be several air intakes 23, which are respectively opened around the heat dissipation window 13.

[0040] like Figure 1 , Figure 3 , Figure 11 As shown, an operable door 27 is provided at one end of the energy storage box 1, and an operable window 28 is hinged below the operable door 27. The charging device 3 is installed inside the operable door 27. The charging device 3 includes a control unit 29, a main unit 30, and a charging gun (not shown in the figure).

[0041] Example 2: Figure 12 As shown, the technical solution of this embodiment differs from that of Embodiment 1 in that this embodiment provides a mobile integrated power storage and charging control system, including a main control module for coordinating and controlling the operation of the entire system; The heat dissipation control module is electrically connected to the circulating pump in the heat conduction cooling system. It is used to control the start, stop and operating power of the circulating pump according to the battery temperature information, and drive the coolant to circulate in the heat conduction cavity. The charge / discharge management module is electrically connected to each battery and charging device to monitor the charge / discharge status, voltage, and current of the battery, and to control the output of the charging device. The thermal management strategy module is connected to the main control module, the heat dissipation control module and the charge and discharge management module. It is used to dynamically formulate and execute heat dissipation strategies and charge and discharge power strategies based on the battery's charge and discharge status, temperature distribution and ambient temperature. The main control module, heat dissipation control module, charge and discharge management module and thermal management strategy module are all integrated in the control box 31, which is installed in the energy storage box 1.

[0042] The heat dissipation control module is configured as follows: When the battery temperature reaches or exceeds the first preset threshold, the power of the circulation pump is started or increased. When the battery temperature is below the second preset threshold, the power of the circulation pump is turned off or reduced.

[0043] It also includes a thermal management strategy module, which coordinates and controls the heat dissipation control module and the charge / discharge management module based on the battery's charge / discharge status and temperature.

[0044] The thermal management strategy module is configured to pre-start the circulation pump when the equipment is running at high power, and control the charge and discharge management module to perform time-sharing or grouped alternating charge and discharge on the multilayer batteries.

[0045] Working principle: S1. Heat Collection and Homogenization Stage: The heat generated by each battery 2 during operation is first conducted through its outer casing. The S-shaped heat-conducting strip 6 at the bottom of the upper support plate 4 is in direct contact with the top of the lower battery 2, becoming the primary heat collection point. The heat-conducting cavity 8 filled with coolant inside the heat-conducting strip 6 absorbs this heat. Crucially, all the heat-conducting cavities 8 on the support plate 4 are connected in series through the first connecting pipe 16 and the second connecting pipe 17 to form an S-shaped closed loop. When the circulation pump 10 is started, the coolant flows throughout the loop, "mixing" and carrying away the heat generated by each battery 2, achieving uniform heat distribution in both horizontal (between different batteries 2 in the same layer) and vertical (between batteries 2 in different layers), avoiding excessively high local temperatures.

[0046] S2. Heat Transfer and Initial Heat Dissipation Stage: The coolant carrying heat from battery 2 flows through the heat dissipation pipe 11 located between the uppermost battery 2 and the top wall of the energy storage tank 1, driven by the circulation pump 10. The heat dissipation pipe 11 is also arranged in an S-shape to increase the heat dissipation area, and its surface is typically equipped with heat dissipation fins 21 to further enhance heat exchange capacity. At this time, the fan 12, mounted on the heat dissipation window 13, starts and blows air onto the heat dissipation pipe 11. The cold air flows over the surface of the heat dissipation pipe 11 and its heat dissipation fins 21, undergoing forced convection heat exchange with the high-temperature coolant inside the pipe, carrying away a large amount of heat from the coolant, thus achieving the first heat transfer and dissipation.

[0047] S3, Directional Enhanced Exhaust Stage: The heat dissipation window 13 is not a simple louver. Its opening and closing are controlled by a pressure device consisting of a sealing sleeve 14 and a sealing column 15. When strong heat dissipation is required, the heat dissipation window 13 is pushed open at a certain angle. At this time, the fan 12 also tilts, forming an angle with the horizontal plane. The air blown out by the fan 12 becomes hot air after cooling the heat dissipation pipe 11. This hot air blows towards the top of the uppermost battery 2 under the action of inertia, and is then blocked and rebounded by the tilted inner wall of the heat dissipation window 13. Several rebound disturbances are formed in the narrow space between the heat dissipation window 13 and the top of the uppermost battery 2, which greatly enhances the heat exchange between the airflow and the heat source (heat dissipation pipe 11 and the top of battery 2). Finally, the hot air is concentrated and directionally discharged out of the box at high speed along the opening direction of the heat dissipation window 13. This "rebound-directional" exhaust duct greatly improves the heat dissipation efficiency compared with direct blowing and direct exhaust, and effectively prevents hot air from circulating and accumulating in the box.

[0048] S3.1 When it rains, in order to prevent rain, the heat dissipation window 13 can be closed. At this time, the fan 12 is reversed to the external exhaust state, so that the heat inside the energy storage box 1 is discharged through the interlayer 22 and the air inlet 23 (in this state: the air inlet 23 is actually the air outlet), thereby achieving the purpose of heat dissipation.

[0049] S4. Auxiliary heat dissipation and structural function synergy: In addition to the active heat dissipation system, the equipment is also designed with an auxiliary heat dissipation structure. The connecting groove 20 on the support plate 4 allows air to circulate between the support plates 4, promoting the natural rise of hot air and working in synergy with the forced air duct at the top. The battery 2 slides with the limiting strip 18 in the mounting groove 5 through the limiting groove 19 on the side, ensuring neat installation and providing a regular space for effective contact and air circulation of the heat conduction strip 6. The charging device 3 is integrated into the movable door 27 for easy operation and maintenance. The design of the interlayer 22, waterproof slope 24 and step 26 of the heat dissipation window 13 effectively prevents rainwater intrusion when the heat dissipation is turned on, ensuring the safety of outdoor use.

[0050] In summary, the composite heat dissipation system, which combines coolant circulation driven by the circulating pump 10 with forced ventilation by the fan 12, completely changes the passive heat dissipation mode that relies solely on natural airflow. The coolant flows within the heat conduction cavity 8, actively collecting and transferring heat from each layer of battery 2. Then, through forced heat exchange via the heat pipe 11 and the fan 12, the heat is efficiently discharged outside the energy storage tank 1. This active thermal management can dynamically adjust the heat dissipation intensity according to the internal temperature, ensuring excellent heat dissipation performance even under high load or high temperature environments, effectively preventing heat accumulation. The heat conduction strip 6 directly contacts the battery 2, achieving initial heat collection. The S-shaped interconnected heat conduction cavity 8 network connects and evens out the heat from all batteries 2, avoiding localized overheating. The heat is ultimately concentrated on the top heat dissipation pipe 11 for centralized heat dissipation. This tiered heat conduction mode ensures that the heat of each battery in the stacked battery 2 can be effectively incorporated into the management cycle, improving overall thermal balance and extending the battery 2's lifespan. An efficient directional exhaust airflow is formed through the openable heat dissipation window 13 and its linked tilting fan 12. The tilted airflow of the fan 12 causes the air to bounce multiple times between the top of the uppermost battery 2 and the heat dissipation window 13 after impacting the heat dissipation pipe 11, finally exiting directionally from the opening of the heat dissipation window 13. This design forces hot air to flow rapidly along a preset path, greatly improving the heat exchange efficiency between the airflow and the heat source, and effectively preventing hot air from stagnating and flowing back inside the chamber. This achieves rapid forced heat dissipation, optimizes the internal space and airflow organization, and enhances overall heat dissipation performance. By creating connecting slots 20 on the support plate 4, vertical air channels are created between layers while ensuring structural strength. This not only facilitates natural air convection and assists in upward heat transfer, but also combines with the forced air duct at the top to form a coordinated "bottom-in, top-out" airflow organization. Combined with the neat and limited installation of the batteries 2, this ensures a regular internal space and unobstructed airflow path, allowing the active cooling system and passive airflow to complement each other and comprehensively improve the heat dissipation effect. The sandwich structure 22 of the heat dissipation window 13, the waterproof slope 24, and the step 26 design provide excellent rain and water resistance while achieving efficient heat dissipation, ensuring equipment safety in complex outdoor environments. Key heat dissipation components such as the heat conduction cavity 8 and the circulation pipe 9 are built-in or protected, reducing the risk of external damage. The entire heat dissipation system has a high degree of integration and stable operation, significantly improving the operational reliability and environmental adaptability of the energy storage power equipment under long-term, high-power conditions.

Claims

1. A mobile integrated energy storage and charging power supply device, comprising an energy storage box and a plurality of batteries and at least one charging device installed inside the energy storage box, characterized in that: Several batteries are stacked in multiple layers inside the energy storage box. Each layer of batteries is supported by a support plate. The support plate has several mounting slots along its horizontal direction. Each mounting slot holds two symmetrical batteries along its vertical direction, with the terminals of the two batteries facing outwards. Several heat-conducting strips are connected to the bottom of each support plate. Each heat-conducting strip is S-shaped and covers the top projection surface of the mounting slot. The heat-conducting strips protrude from the bottom surface of the support plate. The bottom of the heat-conducting strip on the upper support plate contacts the top of the battery on the lower support plate, forming a heat dissipation gap between the bottom of the upper support plate and the top of the lower battery. The heat-conducting strips have heat-conducting cavities inside, which are filled with coolant. The two ends of the heat-conducting cavities extend to one end of the support plate. The heat-conducting cavities below the mounting slots on several support plates are connected in sequence. The beginning and end of the heat-conducting cavities on several support plates are connected by a circulation pipe. A circulation pump is installed in the middle of the circulation pipe. The circulation pump drives the coolant inside the heat-conducting cavities to flow, dispersing the heat of each battery.

2. The mobile integrated power storage and charging device as described in claim 1, characterized in that: A heat dissipation pipe is also installed in the middle of the circulation tube. The heat dissipation pipe is located between the top of the uppermost battery and the top of the inner wall of the energy storage box. The heat dissipation pipe is S-shaped. A fan is installed on the top of the energy storage box, and the fan blows air towards the heat dissipation pipe.

3. The mobile integrated power storage and charging device as described in claim 2, characterized in that: The top of the energy storage box is equipped with a heat dissipation window, and the fan is mounted on the heat dissipation window. One end of the heat dissipation window is hinged to the top of the energy storage box, and both ends of the heat dissipation window are fixedly connected to sealing sleeves. The sealing sleeves are internally sealed and slidably connected to sealing columns. The bottom of the sealing columns is fixedly connected to the top of the energy storage box, and the middle of the sealing columns has a through hole. The through hole is connected to an external pressure device to apply pressure to the inside of the sealing sleeves, causing the sealing sleeves to move relative to the sealing columns, thereby driving the heat dissipation window to open and close. When the heat dissipation window is open, several fans form an angle with the top battery and heat dissipation pipes. The air blown out by the fans passes through the heat dissipation pipes and then bounces continuously between the top battery and the heat dissipation window before finally being blown out from the opening of the heat dissipation window.

4. The mobile integrated power storage and charging device as described in claim 1, characterized in that: Several heat-conducting cavities on each carrier plate are connected end to end by a first connecting pipe, and the heat-conducting cavities at the very end of two adjacent carrier plates are connected end to end by a second connecting pipe. The heat-conducting cavities on several carrier plates are S-shaped along the orthogonal projection direction of the energy storage box.

5. A mobile integrated power storage and charging device as described in claim 1, characterized in that: The inner wall of the mounting slot is fixed with a limiting strip, and the two sides of the battery are provided with limiting grooves that match the limiting strip. The limiting grooves and the limiting strip are slidably connected, so that several batteries can be installed at the same height in the mounting slot.

6. A mobile integrated power storage and charging device as described in claim 1, characterized in that: Each mounting slot has several connecting slots inside, which connect the upper and lower parts of the support plate and avoid the heat conduction cavity.

7. A mobile integrated power storage and charging device as described in claim 4, characterized in that: The surfaces of the first connecting pipe, the second connecting pipe, and the heat dissipation pipe are all fixed with heat dissipation fins. The heat dissipation fins increase the heat exchange area, allowing the heat of the coolant inside to be quickly exchanged with the cold air.

8. A mobile integrated power storage and charging device as described in claim 3, characterized in that: A sandwich layer is provided in the middle of the heat dissipation window, and the fan is installed below the sandwich layer. An air inlet is provided at one end of the sandwich layer near the hinge axis of the heat dissipation window. A waterproof slope is provided below the air inlet. The waterproof slope slopes outwards when the heat dissipation window is open or closed.

9. A mobile integrated power storage and charging device as described in claim 1, characterized in that: The energy storage box has a movable door at one end, and a movable window is hinged below the movable door. The charging equipment is installed inside the movable door and includes a control unit, a main unit, and a charging gun.

10. A mobile integrated power storage and charging control system, used in the mobile integrated power storage and charging device according to any one of claims 1-9, characterized in that: Includes the main control module, which is used to coordinate and control the operation of the entire system; The heat dissipation control module is electrically connected to the circulating pump in the heat conduction cooling system. It is used to control the start, stop and operating power of the circulating pump according to the battery temperature information, and drive the coolant to circulate in the heat conduction cavity.
