Description

Technical Field

[0001] This invention relates to the field of temperature control technology for energy storage modules, and in particular to an automatic temperature control unit for multiple environments in an energy storage module and its control method. Background Technology

[0002] In the field of energy storage technology, especially electrochemical energy storage such as lithium-ion batteries and lead-acid battery modules, the performance, lifespan, and safety are highly dependent on the operating temperature. Excessively high temperatures accelerate battery aging and trigger thermal runaway risks; excessively low temperatures lead to increased internal resistance, a sharp drop in usable capacity, and charging difficulties. To maintain the operation of energy storage modules within a suitable temperature range, existing technologies generally employ thermal management systems (TMS). Common solutions include forced air cooling based on air convection, liquid cooling based on liquid circulation, and passive temperature control utilizing phase change materials (PCMs) for heat absorption / release. The main goal of these systems is to promptly remove waste heat generated inside the module or provide necessary insulation / heating when the external environment is low, thereby ensuring its basic operational efficiency.

[0003] However, existing temperature control technologies for energy storage modules have certain limitations. Their control strategies and structural designs are often relatively simple, lacking the ability to proactively adapt to dynamic changes in ambient temperature. Specifically, most systems are optimized for specific operating conditions such as normal temperature or preset high-temperature environments, making it difficult to achieve efficient and adaptive thermal management under complex and variable environmental temperature conditions such as large diurnal temperature differences, seasonal changes, or significant regional climate differences. For example, traditional heat dissipation solutions may be insufficient in extreme high temperatures, while failing to effectively maintain module temperature in frigid environments. Furthermore, switching between different control modes usually relies on fixed thresholds or manual intervention, lacking an intelligent and integrated control mechanism. Therefore, existing technologies suffer from insufficient adaptability in temperature regulation methods and difficulty in effectively coping with the challenges of a wide range and dynamic changes in ambient temperature, thus restricting the reliability, energy efficiency, and lifespan of energy storage modules in complex application scenarios. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the current adjustment methods of energy storage modules are relatively simple and difficult to adapt to temperature changes in different environments.

[0005] The first aspect of the present invention provides an automatic temperature control unit for multiple environments of an energy storage module, including an external protective frame installed on the outside of the energy storage module. The external protective frame has an internal heat exchange channel for adjusting the temperature of the energy storage module. An electrically controlled top-flipping cover connected to the internal heat exchange channel is provided on the upper surface of the external protective frame. A bottom heat exchange box is fixedly installed at the lower end of the external protective frame. A guide pump for driving the heat exchange medium to circulate in the internal heat exchange channel and the electrically controlled top-flipping cover is installed inside the bottom heat exchange box.

[0006] Furthermore, the external protective frame includes a bottom protective box fixed to the outside of the energy storage module, an upper lifting cover slidably sleeved on the upper end of the bottom protective box, and an embedded lifting mechanism fixedly connected to the bottom protective box; the electrically controlled top flip cover is disposed on the upper lifting cover.

[0007] Furthermore, the upper end of the upper lifting cover is provided with a plurality of upper heat dissipation vents, and the electrically controlled top flip cover is movably installed at the position of the upper heat dissipation vents.

[0008] Furthermore, the electrically controlled top-flipping cover includes a flipping heat-conducting cover plate movably mounted at the position of the upper heat dissipation vent, a control screw rotatably mounted on the inner bottom surface of the upper lifting cover, an internally threaded translation seat threaded onto the control screw, and a movable control link with both ends respectively hinged to the flipping heat-conducting cover plate and the internally threaded translation seat; when the control screw rotates, it drives the flipping heat-conducting cover plate to flip through the internally threaded translation seat and the movable control link to open and close the upper heat dissipation vent.

[0009] Furthermore, a graphene layer for improving thermal conductivity is fixedly mounted on the bottom surface of the flip-up heat-conducting cover facing the energy storage module.

[0010] Furthermore, the lower surface of the upper heat dissipation port is provided with a U-shaped sealing frame that cooperates with the flip-up heat-conducting cover when closed, and the inner side of the upper heat dissipation port is provided with a lateral assembly guide hole that cooperates with the internal heat exchange channel.

[0011] Furthermore, the flip-up heat-conducting cover plate is provided with a top heat exchange channel inside, and both sides of the flip-up heat-conducting cover plate are provided with assembly shaft tubes that match the lateral assembly guide holes.

[0012] Furthermore, a bottom guide pipe is fixedly mounted on the top surface of the upper lifting cover, and the bottom guide pipe is connected to the interior of the side-mounted guide hole; an upper guide hole that cooperates with the bottom guide pipe is opened at the upper end of the bottom protective box; the lower end of the upper guide hole is connected to the internal heat exchange channel.

[0013] Furthermore, both the bottom guide pipe and the upper guide hole are equipped with elastic valve cores. When the upper lifting cover descends to the working position, the bottom guide pipe is inserted into the upper guide hole and overcomes the elastic force of the elastic valve core to connect the flow channels. When the upper lifting cover is raised, the elastic valve cores reset and close their respective flow channels. Temperature sensing and control modules for monitoring the environment and energy storage module temperature are fixedly installed on both the upper and lower surfaces of the upper lifting cover.

[0014] The second aspect of the present invention provides a method for adapting and regulating multiple ambient temperatures in an energy storage module, applied to the automatic temperature regulation unit for multiple ambient temperatures in an energy storage module described in the first aspect of the present invention, characterized in that the method includes: The temperature sensing and control module is used to monitor the internal temperature of the energy storage module and the external ambient temperature. If the external temperature is higher than the internal temperature, or if the external temperature is lower than the internal temperature but the internal temperature is within the preset operating temperature range, the current state of the control unit will be maintained. If the internal temperature is higher than the external temperature and the internal temperature is higher than the preset high temperature threshold, then: the flow pump is started to drive the heat exchange medium to circulate, and the heat from the top of the energy storage module is conducted to the flip-up heat-conducting cover through the graphene layer, and then discharged to the bottom protective box for heat dissipation through the top heat exchange channel and the internal heat exchange channel; the flip-up heat-conducting cover is controlled to flip upward to open the upper heat dissipation port to enhance air convection heat dissipation, and the flip-up direction of the flip-up heat-conducting cover is controlled to face the direction of light to block the light. If the ambient temperature is lower than the preset low temperature threshold, then: control the embedded elevator to raise the upper lifting cover, forming a heat storage chamber between the upper lifting cover and the energy storage module; start the guide liquid pump to drive the heat exchange medium to circulate in the internal heat exchange channel, and distribute the heat in the heat storage chamber to the energy storage module to avoid the energy storage module from losing temperature.

[0015] The present invention has the following beneficial effects: This invention achieves dynamic reconfiguration of the thermal management mode of the energy storage module by integrating a liftable top-mounted lifting cover structure, an electrically controlled top-flipping cover with a flip-up heat-conducting cover, and an internal heat exchange channel system driven by a guide liquid pump. In high-temperature environments, heat dissipation is enhanced by liquid cooling circulation combined with top heat conduction and openable heat dissipation vents, while the flip-up cover blocks sunlight. In low-temperature environments, the lifting cover forms a heat storage chamber, and heat is evenly distributed through liquid circulation for insulation. The multi-ambient temperature automatic control unit of this energy storage module improves its adaptability to a wide range of dynamic environmental temperatures. It intelligently switches between heat dissipation and insulation modes through changes in physical structure, overcoming the shortcomings of traditional solutions, such as single adjustment methods and insufficient environmental adaptability. At the same time, the integrated protective frame design enhances the external protection of the module while providing temperature control functions, and the automatic control based on temperature sensing ensures the accuracy of the control process and energy efficiency optimization. Ultimately, without the need to introduce complex external systems, it effectively ensures the working temperature stability, safety, and service life of the energy storage module under complex conditions.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] The following description, in conjunction with the accompanying drawings, details the specific scheme of the automatic ambient temperature control unit and its control method for an energy storage module provided by the present invention.

[0021] Please see Figures 1 to 3As shown, an embodiment of the present invention provides an automatic temperature control unit for an energy storage module, comprising an external protective frame installed outside the energy storage module. The external protective frame contains an internal heat exchange channel 1 for regulating the temperature of the energy storage module. An electrically controlled top-flipping cover, connected to the internal heat exchange channel 1, is located on the upper surface of the external protective frame. A bottom heat exchange box 2 is fixedly mounted at the lower end of the external protective frame. A guide pump 3, for driving the heat exchange medium to circulate within the internal heat exchange channel 1 and the electrically controlled top-flipping cover, is installed inside the bottom heat exchange box 2. The external protective frame serves as the mounting base for the entire unit, primarily providing structural support and protection for the internal components. Simultaneously, its fixed connection with the energy storage module ensures a close connection between the temperature control unit and the controlled object. The system is designed with the following components: The internal heat exchange channel 1, embedded within the external protective frame, is the core path for heat transfer. It uses a circulating heat exchange medium, such as a dedicated coolant, to conduct or transfer heat generated by the energy storage module. The electrically controlled top-tilting cover connects to the internal heat exchange channel 1, serving both heat conduction and heat dissipation regulation functions. Its tilting action alters the heat exchange efficiency with the external environment and extends the heat exchange medium circulation path, enhancing top heat dissipation efficiency. The bottom heat exchange box 2 serves as both a storage container for the heat exchange medium and one of the heat exchange terminals. It releases the heat conducted from the internal heat exchange channel through natural convection or forced cooling with the external environment. A guide pump 3 acts as a power source, driving the heat exchange medium to circulate between the internal heat exchange channel 1 and the electrically controlled top-tilting cover, ensuring the continuity and efficiency of heat transfer. This energy storage module's multi-ambient temperature automatic control unit integrates a dynamically adjustable mechanical structure and intelligent control logic, enabling flexible switching of thermal management modes: at high temperatures, it enhances heat dissipation through liquid cooling circulation, opening of top heat dissipation vents, and light blocking; at low temperatures, it achieves insulation by raising the enclosure to form a heat storage chamber and evenly distributing heat, effectively solving the problems of traditional temperature control methods, such as single adjustment and poor environmental adaptability; at the same time, the integrated protective frame enhances the module's external protection capabilities, and sensor-based automatic control ensures precise regulation, guaranteeing the energy storage module's operational stability, safety, and service life in diverse environments without the need for complex external systems.

[0022] Preferably, the external protective frame includes a bottom protective box 4 fixed to the outside of the energy storage module, an upper lifting cover 5 slidably sleeved on the upper end of the bottom protective box 4, and an embedded lifting mechanism 6 fixedly connected to the bottom protective box 4; the electrically controlled top flip cover is disposed on the upper lifting cover 5. Specifically, the upper lifting cover 5 is a movable structure that can be raised and lowered. It achieves a flexible connection with the bottom protective box 4 through a sliding sleeve. Its raising and lowering action can change the spatial distance between it and the energy storage module, thereby adjusting the closed and open nature of heat exchange. When lowered, it can compress space to enhance convection heat dissipation; when raised, it can form a heat storage chamber to enhance the heat preservation effect. At the same time, the electrically controlled top flip cover carried on it is a key carrier for realizing top heat dissipation and light blocking. The embedded lifting mechanism 6, as a power actuation component, precisely controls the raising and lowering height of the upper lifting cover 5 through the telescopic movement of its top extension end. Its fixed connection with the bottom protective box 4 ensures the stable transmission of driving force. The bottom protective box 4 can be made of high-strength aluminum alloy, with an overall rectangular frame structure. Its inner wall is rigidly connected to the outer wall of the energy storage module by bolts, and the inner side of the box has a groove reserved to accommodate the internal heat exchange channel. Rubber shock-absorbing pads can also be installed at the four corners of the bottom of the box to reduce the vibration transmission during the operation of the energy storage module. Two parallel vertical slide rails can be installed on the outer side of the upper end of the box to guide the sliding of the upper lifting cover 5. The upper lifting cover 5 is made of lightweight magnesium alloy, with an overall rectangular cover with an open bottom. Matching sliders are set on its inner side wall corresponding to the slide rail positions of the bottom protective box 4. The sliding cooperation between the slider and the slide rail achieves the engagement with the bottom protective box 4 to ensure smooth lifting. Four upper heat dissipation vents 7 are evenly opened on the upper end face of the cover for installing an electrically controlled top flip cover. An annular sealing strip is set on the inner side of the lower end of the cover. When the upper lifting cover 5 is lowered to the lowest position, the sealing strip is tightly fitted to the upper end face of the bottom protective box 4 to enhance the sealing of the internal space. The embedded lifting platform 6 can adopt an electric push rod structure. Its cylinder is fixed to the middle position of the inner wall of the bottom protective box 4 through a flange, and the top protruding end is connected to the inner top surface of the upper lifting cover 5 through a ball joint. The control circuit of the embedded lifting platform 6 can be integrated into the wiring groove inside the bottom protective box 4 and connected to the signal output terminal of the temperature sensing control module 19 to achieve precise adjustment of the lifting height. In practical applications, when the temperature sensing and control module 19 detects that the external temperature is lower than the preset low temperature threshold, it sends a lifting signal to the embedded elevator 6. The top extension of the elevator extends, pushing the upper lifting cover 5 to slide upward along the slide rail. At this time, a closed heat storage chamber is formed between the upper lifting cover 5 and the top of the energy storage module. When it is detected that heat dissipation is needed or the initial state is restored, the elevator extension retracts, driving the upper lifting cover 5 to descend until the sealing strip is in contact with the bottom protective box 4. At this time, the heat storage chamber is closed, and the internal heat exchange channel and the channel of the electrically controlled top flip cover are connected through the cooperation of the bottom guide pipe and the upper guide hole. This embodiment, through the coordinated design of a bottom protective box 4, an upper lifting cover 5, and an embedded lifting mechanism 6, enables the external protective frame to have both structural protection and dynamic adjustment functions. The sliding lifting of the upper lifting cover 5 realizes the opening and closing of the heat storage chamber and the adjustment of its size, while the embedded lifting mechanism 6 ensures the precise controllability of the adjustment process. The combination of the three upgrades the external protective frame from a static protective structure to a functional carrier that can actively adapt to changes in ambient temperature, providing reliable structural support for switching between high-temperature heat dissipation and low-temperature heat preservation modes.

[0023] Preferably, the upper end of the upper lifting cover 5 has a plurality of upper heat dissipation vents 7, and the electrically controlled top flip cover is movably installed at the position of the upper heat dissipation vents 7. Specifically, the upper heat dissipation vents 7 serve as channels for top heat exchange, and their opening and closing states are controlled by the electrically controlled top flip cover. When open, air convection can be used for heat dissipation, and when closed, heat loss can be effectively reduced. At the same time, the electrically controlled top flip cover itself can also serve as an extension of the heat exchange medium circulation path, improving the efficiency of top heat removal. The upper end face of the upper lifting cover 5 has a plurality of upper heat dissipation vents 7 arranged in an array, with the spacing between adjacent upper heat dissipation vents 7 preferably 5 cm, and the plurality of upper heat dissipation vents 7 are distributed parallel to each other along the length of the cover. A lateral assembly guide hole should be reserved in the middle of the inner wall of the upper heat dissipation port 7 to form a communication path with the internal heat exchange channel 1; each upper heat dissipation port 7 is equipped with a set of electrically controlled top flip cover: the flip heat conduction cover plate 8 is made of aluminum alloy, with a flange on the edge and a U-shaped sealing frame 13 in the mounting groove of the upper heat dissipation port 7 to achieve a seal; the bottom surface of the flip heat conduction cover plate 8 is attached to the graphene layer 12, and the inside can adopt a serpentine top heat exchange channel 14, and the two ends are sealed and connected to the lateral assembly guide hole through the assembly shaft tube 15; the control screw 9 is fixed to the inner bottom surface of the upper lifting cover 5 through the bearing seat, driven by a servo motor, and its surface thread is engaged with the internal thread translation seat 10. The translation seat is hinged to the flip heat conduction cover plate 8 through two movable control connecting rods 11, and the two ends of the connecting rod can adopt a ball joint structure to ensure the flip flexibility. On the other hand, depending on actual needs, a horizontal heat dissipation vent can be opened on the outer side of the bottom protective box 4. An electrically controlled telescopic cover is installed inside the horizontal heat dissipation vent, which can extend outward when heat dissipation is needed to increase the heat dissipation outside the internal heat exchange channel 1. When the external temperature is low, the horizontal heat dissipation vent can also be closed by the electrically controlled telescopic cover. In this embodiment, by setting an adjustable upper heat dissipation vent 7 and an electrically controlled top flip cover in the upper lifting cover 5, combined with the horizontal heat dissipation vent and electrically controlled telescopic cover of the bottom protective box 4, a multi-directional and dynamically adjustable heat dissipation channel system is constructed, realizing the control of heat dissipation area and sealing performance. The electrically controlled top flip cover has both heat conduction and shielding functions. The horizontal heat dissipation vent and the telescopic cover enhance the flexibility of side heat exchange. The two work together to improve the heat exchange efficiency of the energy storage module under different ambient temperatures, which not only strengthens the heat dissipation capacity at high temperatures, but also ensures the heat preservation effect at low temperatures. At the same time, the sealing design reduces ineffective heat loss, further improving the environmental adaptability and operational stability of the entire temperature control unit.

[0024] Preferably, the electrically controlled top-flipping cover includes a flipping heat-conducting cover plate 8 movably mounted at the upper heat dissipation vent 7, a control screw 9 rotatably mounted on the inner bottom surface of the upper lifting cover 5, an internally threaded translation seat 10 threaded onto the control screw 9, and a movable control link 11 hinged at both ends to the flipping heat-conducting cover plate 8 and the internally threaded translation seat 10, respectively. When the control screw 9 rotates, it drives the flipping heat-conducting cover plate 8 to flip through the internally threaded translation seat 10 and the movable control link 11 to open and close the upper heat dissipation vent 7. As the core component for power transmission, the control screw 9 drives the internally threaded translation seat 10 threaded to it to translate axially through forward and reverse rotation, converting rotational motion into linear motion. The displacement of the internal thread translation seat 10 is transmitted to the flip heat-conducting cover plate 8 through the movable control link 11. Utilizing the hinge characteristic of the movable control link 11, the translational motion is converted into the flipping motion of the cover plate. When the internal thread translation seat 10 moves forward, the movable control link 11 pushes one end of the cover plate to lift, thereby opening the upper heat dissipation port 7. When the translation seat moves backward, the movable control link 11 pulls the cover plate to reset, thereby closing the heat dissipation port. The servo motor control terminal and the temperature sensing control module 19 can be connected via pulse signals. The module outputs pulse commands based on the collected temperature data to control the forward and reverse rotation and rotation angle of the motor, thereby precisely adjusting the displacement of the internal thread translation seat 10, so that the flipping angle of the heat-conducting cover 8 can be continuously adjusted within the range of 0°-60°. In this embodiment, through the coordinated transmission of the control screw 9, the internal thread translation seat 10 and the movable control linkage 11, the precise opening and closing and angle adjustment of the heat dissipation port of the flipping heat-conducting cover 8 are realized. This ensures the sealing of the heat dissipation port when closed to reduce heat loss, and allows for flexible adjustment of the convection heat dissipation area by changing the angle when open.

[0025] Preferably, a graphene layer 12 for improving thermal conductivity is fixedly mounted on the bottom surface of the flip-up heat-conducting cover 8 facing the energy storage module. In actual use, when the flip-up heat-conducting cover 8 flips downward, the lower surface of the graphene layer 12 contacts the upper surface of the energy storage module, thereby quickly transferring the heat from the energy storage module to the flip-up heat-conducting cover 8, improving heat transfer efficiency. On the other hand, when the cover is open, the graphene layer 12 can still indirectly absorb some heat through air convection, assisting in heat dissipation. When the temperature sensing control module 19 triggers the heat dissipation mode, the servo motor drives the control screw 9 to reverse, the internal thread translation seat 10 moves closer to the motor end, and the movable control linkage 11 pulls the flip-up heat-conducting cover 8 downward until the lower surface of the graphene layer 12 is completely in contact with the upper surface of the energy storage module. A pressure sensor can also be set at the edge of the cover to monitor the contact pressure in real time. When the pressure reaches a preset value, the motor stops, ensuring that the graphene layer is in close contact with the module surface without excessive compression.

[0026] Preferably, the lower surface of the upper heat dissipation vent 7 is provided with a U-shaped sealing frame 13 that cooperates with the flip-up heat-conducting cover 8 when closed, and the inner side of the upper heat dissipation vent 7 is provided with a lateral assembly guide hole that cooperates with the internal heat exchange channel 1. Specifically, by dividing the functions of the U-shaped sealing frame 13 and the lateral assembly guide hole, the problem of switching between sealing and heat dissipation modes of the upper heat dissipation vent 7 can be solved: the U-shaped sealing frame 13 can ensure the spatial airtightness when the flip-up heat-conducting cover 8 is closed, blocking unnecessary air convection and ensuring the heat storage effect in low-temperature environments; combined with the lateral assembly guide hole as the connection interface between the internal heat exchange channel and the top channel, the heat transfer path is extended, while providing a flow channel for the heat exchange medium. The synergistic design of the two enables the upper heat dissipation vent 7 to not only actively dissipate heat as a heat dissipation channel, but also transform into a heat exchange node to participate in heat transfer when closed, and block heat loss through sealing, thereby improving the structural functionality and environmental adaptability. The U-shaped sealing frame 13 can be made of silicone rubber, with a trapezoidal cross-section and reinforcing ribs on the inner side. It is then glued to the lower edge of the upper heat dissipation port 7 with high-strength adhesive, corresponding to the flange of the edge of the flip-up heat-conducting cover plate 8. When the cover plate is closed, the sealing frame is compressed to form a closed sealing ring, blocking air flow. When the flip-up heat-conducting cover plate 8 is in the closed state, its edge flange presses against the U-shaped sealing frame 13, and at the same time, the mounting shaft tube 15 is inserted into the lateral mounting guide hole and compresses the sealing ring, achieving a dual sealing effect of space sealing and flow channel sealing. When the cover plate is opened, the mounting shaft tube 15 is disengaged from the guide hole, the sealing ring rebounds, the flow channel is automatically closed, and the U-shaped sealing frame 13 is released from compression, the upper heat dissipation port 7 is opened, and the air convection channel is opened.

[0027] Preferably, the flip-up heat-conducting cover plate 8 has a top heat exchange channel 14 inside, and each of the two side walls of the flip-up heat-conducting cover plate 8 has an assembly shaft tube 15 that matches the lateral assembly guide hole. The assembly shaft tubes 15 on both sides of the flip-up heat-conducting cover plate 8 are inserted into the lateral assembly guide hole, so that the internal heat exchange channel 1 is connected to the top heat exchange channel 14. By setting the top heat exchange channel 14 inside the flip-up heat-conducting cover plate 8, and cooperating with the precise docking of the two side assembly shaft tubes 15 with the lateral assembly guide hole, a complete heat exchange medium circulation path is constructed that runs through the internal heat exchange channel and the top area. When the flip-up heat-conducting cover plate 8 is closed, the assembly shaft tube 15 is inserted into the lateral assembly guide hole, so that the internal heat exchange channel is connected to the top heat exchange channel, and the heat exchange medium can circulate under the drive of the guide liquid pump, so as to efficiently export the heat conducted by the energy storage module to the cover plate through the graphene layer 12; when the cover plate is flipped open, the assembly shaft tube 15 is separated from the guide hole, the channel is automatically cut off, and the medium leakage is avoided. The lateral assembly guide hole is located on the inner wall of the upper heat dissipation port 7, and the hole axis is coaxial with the axis of the assembly shaft tube 15. When the flip-up heat-conducting cover plate 8 is closed, the servo motor drives the control screw 9 to reverse, and the internal thread translation seat 10 pulls the cover plate downward to flip it. The assembly shaft tube 15 is inserted into the lateral assembly guide hole along the guide slope until the edge of the cover plate fits with the U-shaped sealing frame 13. In this embodiment, the heat exchange area is effectively expanded by the serpentine top heat exchange channel 14. Combined with the heat conduction and sealing design of the assembly shaft tube 15, the heat exchange medium is stably circulated in the internal channel and the top area, which improves the heat transfer efficiency. At the same time, the precise docking of the assembly shaft tube 15 and the lateral guide hole ensures the reliability and sealing of the channel opening and closing, which not only avoids the risk of medium leakage, but also allows the heat exchange path to be adaptively adjusted according to the flip state of the cover plate.

[0028] Preferably, a bottom guide pipe 16 is fixedly mounted on the inner top surface of the upper lifting cover 5, and the bottom guide pipe 16 is connected to the interior of the side assembly guide hole; the upper end of the bottom protective box 4 is provided with an upper guide hole 17 that cooperates with the bottom guide pipe 16; the lower end of the upper guide hole 17 is connected to the internal heat exchange channel 1; in this embodiment, an internal guide hole is opened inside the upper lifting cover 5 to connect the side assembly guide hole and the interior of the bottom guide pipe 16. When the bottom guide pipe 16 is inserted into the interior of the upper guide hole 17, the internal heat exchange channel 1 will be connected to the top heat exchange channel 14 through the internal guide hole, ensuring the internal heat exchange connectivity. Thus, through the coordinated design of the bottom guide pipe 16, the upper guide hole 17 and the internal guide hole, a heat exchange medium circulation channel that can adaptively open and close with the lifting and lowering movement of the upper lifting cover 5 is constructed. The bottom guide pipe 16 serves as the medium transfer carrier within the upper lifting cover 5. It connects to the side assembly guide pipe through the built-in guide hole, forming a continuous path from the top heat exchange channel 14 to the guide pipe. The upper guide hole 17 serves as the medium transfer interface within the bottom protective box 4. Its lower end connects to the internal heat exchange channel 1, and its upper end can connect to the bottom guide pipe 16. When the upper lifting cover 5 descends, the bottom guide pipe 16 is inserted into the upper guide hole 17, forming a closed loop path with the top heat exchange channel 14, the built-in guide hole, the bottom guide pipe 16, the upper guide hole 17, and the internal heat exchange channel 1. When the upper lifting cover 5 is raised, the guide pipe separates from the guide hole, and the loop path is broken. Furthermore, when the temperature sensing control module 19 triggers the heat dissipation mode, the embedded elevator 6 drives the upper lifting cover 5 to descend, and the bottom guide pipe 16 is inserted into the upper guide hole 17. At this time, the circulation path of the top heat exchange channel 14, the side mounting guide hole, the built-in guide hole, the bottom guide pipe 16, the upper guide hole 17, and the internal heat exchange channel 1 is connected, and the guide liquid pump 3 drives the medium to circulate. When the heat preservation mode is triggered, the elevator raises the upper lifting cover 5, and the bottom guide pipe 16 is pulled out from the upper guide hole 17, and the path is disconnected to avoid the medium circulating and consuming energy when it is not necessary.

[0029] Preferably, both the bottom guide pipe 16 and the upper guide hole 17 are equipped with elastic valve cores 18. When the upper lifting cover 5 is lowered to the working position, the bottom guide pipe 16 is inserted into the upper guide hole 17 and overcomes the elastic force of the elastic valve core 18 to connect the flow channels. When the upper lifting cover 5 is raised, the elastic valve core 18 resets and closes its respective flow channel. Temperature sensing and control modules 19 for monitoring the environment and energy storage module temperature are fixedly installed on both the upper and lower surfaces of the upper lifting cover 5. When the embedded lifting platform 6 controls the upper lifting cover 5 to rise, the bottom guide pipe 16 separates from the upper guide hole 17. At this time, the elastic valve core 18 in the bottom guide pipe 16 extends to the opening position, closing the lower opening of the bottom guide pipe 16, while the elastic valve core 18 in the upper guide hole 17 pops up, closing the upper guide hole 17. At this time, the connection between the internal heat exchange channel 1 and the top heat exchange channel 14 is cut off, the circulation loop is interrupted, and the heat exchange medium stops flowing between the two. When the embedded lifting platform 6 controls the upper lifting cover 5 to fall, the bottom guide pipe 16 inserts into the upper guide hole 17. At this time, the elastic valve core in the bottom guide pipe 16 squeezes the elastic valve core in the upper guide hole 17, and the elastic valve core 18 retracts synchronously, so that the top heat exchange channel 14 will connect with the internal heat exchange channel 1.

[0030] The on / off control of the elastic valve core 18 is as follows: the elastic valve core 18 in the bottom guide pipe 16 and the upper guide hole 17 is kept in a normally closed state by means of spring force. When the upper lifting cover 5 is lowered, the valve cores squeeze each other and retract against the spring force, and the flow channel is opened. After the lifting cover is raised, the valve core is reset and closes the flow channel under the action of the spring. The elastic valve core 18 can adopt a modular design, consisting of a valve core body, a compression spring and a guide sleeve. The valve core body inside the bottom guide tube 16 is tapered, with a diameter matching the inner diameter of the guide tube. Its tail slides against a guide sleeve on the inner wall of the guide tube via a guide rod. A spring is fitted around the outside of the guide rod, with one end abutting the tail of the valve core and the other end fixed to the stepped surface inside the guide tube. The valve core structure inside the upper guide hole 17 is symmetrical to the bottom valve core, with the tapered surface of the valve core facing the orifice. The guide sleeve is fixed to the stepped surface inside the orifice, ensuring the valve core moves along its axis. When the upper lifting cover 5 descends, the guide tapered surface of the bottom guide tube 16 contacts and guides the orifice of the upper guide hole 17. After the valve core tapered surface is in contact, as the lifting cover continues to descend, the spring is compressed, and the valve core fully retracts into the guide sleeve, opening the flow channel. At this time, the gap between the valve core and the guide sleeve creates a small throttling effect, which, combined with the sealing ring on the outer circumference of the bottom guide tube, achieves a double seal. When the lifting cover is raised, the spring force pushes the valve core to reset, and the conical surface tightly fits the sealing surface of the guide pipe hole to form a line seal; the temperature sensing control module 19 can use a temperature sensor, with the upper surface sensor installed at the center of the top surface of the upper lifting cover 5 to collect external environmental parameters; the lower surface sensor is installed on the inner bottom surface of the lifting cover and connected to the module main control board through wires; the main control board integrates AD conversion and data processing functions, and when it detects that the internal temperature is higher than the high temperature threshold or the external temperature is lower than the low temperature threshold, it outputs a control signal to the embedded lifting machine 6 and the guide liquid pump 3 to trigger the corresponding action.

[0031] In summary, this embodiment achieves reliable sealing during flow channel separation without additional power through the adaptive on / off design of the elastic valve core 18, preventing heat exchange medium leakage and external impurity intrusion. The dual-point monitoring of the temperature sensing control module 19 provides data support for temperature control mode switching, ensuring that the mechanical action of the elastic valve core 18 matches the actual environmental requirements.

[0032] The second aspect of the present invention proposes a method for adapting and regulating multiple ambient temperatures in an energy storage module, applied to the aforementioned automatic temperature regulation unit for multiple ambient temperatures in an energy storage module, the method comprising: The temperature sensing and control module 19 is used to monitor the internal temperature of the energy storage module and the external ambient temperature. If the external temperature is higher than the internal temperature, or if the external temperature is lower than the internal temperature but the internal temperature is within the preset operating temperature range, the current state of the control unit will be maintained. If the internal temperature is higher than the external temperature and the internal temperature is higher than the preset high temperature threshold, then: the guide liquid pump 3 is started to drive the heat exchange medium to circulate, and the heat from the top of the energy storage module is conducted to the flip-up heat-conducting cover plate 8 through the graphene layer 12, and then discharged to the bottom protective box 4 for heat dissipation through the top heat exchange channel 14 and the internal heat exchange channel 1; the flip-up heat-conducting cover plate 8 is controlled to flip upward to open the upper heat dissipation port 7 to enhance air convection heat dissipation, and the flip-up heat-conducting cover plate 8 is controlled to flip towards the direction of light to block the light. If the ambient temperature is lower than the preset low temperature threshold, then: control the embedded lifting machine 6 to raise the upper lifting cover 5, forming a heat storage chamber between the upper lifting cover 5 and the energy storage module; start the guide liquid pump 3 to drive the heat exchange medium to circulate in the internal heat exchange channel 1, and distribute the heat in the heat storage chamber to the energy storage module to avoid the energy storage module losing temperature.

[0033] The energy storage module multi-ambient temperature adaptation and control method provided in this embodiment collects internal and external temperature data in real time through the temperature sensing and control module 19, and makes intelligent decisions based on preset thresholds to dynamically adjust the system's heat dissipation, heat preservation, or natural state, thereby achieving adaptive control of the energy storage module under different ambient temperatures. When the relationship between the external and internal temperatures is within a safe range, the current state can be maintained to reduce system energy consumption; when the internal temperature is too high and the external temperature is low, heat dissipation is accelerated by combining active liquid cooling circulation with passive air convection, and the cover plate is used to block sunlight to reduce heat radiation; when the external temperature is too low, the upper lifting cover 5 is raised to form a heat storage chamber, and the module temperature is maintained by internal circulation to avoid local temperature loss. The preferred high temperature threshold is 45℃, the preferred low temperature threshold is -5℃, and the preferred operating temperature range is 20-40℃. The guide pump 3 can be frequency-controlled, with an initial flow rate of 5L / min preferred. Dynamic adjustment via a PID algorithm ensures the module temperature remains stable at 40℃±1℃. The flip-up heat-conducting cover 8's flip angle can be dynamically adjusted based on the internal and external temperature difference, and the shading direction can be adjusted in real time via a light sensor. This temperature adaptation control method, through intelligent threshold judgment and multi-modal control strategies, achieves adaptive thermal management of the energy storage module under different ambient temperatures: in high-temperature environments, the module temperature is controlled within a safe range through the synergistic effect of active liquid cooling and passive heat dissipation, while reducing solar thermal radiation; in low-temperature environments, heat loss is effectively reduced through the heat storage chamber and internal circulation, preventing battery performance degradation due to low temperatures. The entire control process requires no manual intervention, has a fast response speed, and low energy consumption, significantly improving the environmental adaptability and service life of the energy storage module, providing a reliable guarantee for the stable operation of large-scale energy storage systems.

The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
