Description

Technical Field

[0001] This application relates to the field of power supply system technology, and in particular to an energy management system and control method for a photovoltaic energy storage charging station. Background Technology

[0002] Energy management equipment is a core component for power plants to monitor, control, and optimize power transmission. Its performance directly affects the stability and efficiency of power plant operation. Currently, energy management equipment typically integrates key components such as controllers, data acquisition units, and circuit breakers. To improve space utilization, a common design is to install the controller close to the chassis wall. However, this equipment is mostly deployed outdoors, and extreme temperature environments pose a severe challenge to its operation. Under high-temperature conditions, the chassis wall is in close contact with the controller, resulting in rapid heat conduction and a sharp rise in controller temperature, leading to performance degradation or even overload derating operation, which seriously threatens the reliability and service life of the equipment.

[0003] To address the controller overheating issue, existing technologies, such as the Chinese patent with publication number "CN221042067U", propose a solution that suspends the controller within the cavity of the enclosure using a support structure. This design, to some extent, blocks heat transfer from the enclosure walls and alleviates the controller overheating problem. However, this solution still has significant drawbacks: First, it does not fully consider the difference in humidity changes between the operating and power-off states of electronic components. During normal operation, the electronic components generate heat, creating a dry microenvironment with a certain degree of moisture resistance. However, after power is cut off, the component temperature drops sharply to ambient temperature. When the surrounding humidity is high, water vapor easily condenses on the surface of the low-temperature components, and due to the lack of continuous heat to dissipate the moisture, it adheres more easily, leading to frequent malfunctions such as oxidation of metal pins and reduced insulation performance of circuit boards, greatly affecting equipment performance and lifespan. Second, existing equipment lacks an automatic control mechanism. It cannot dynamically adjust the heat dissipation intensity according to temperature changes, nor can it promptly activate protective sealing measures when power is cut off. This makes it difficult to adapt to complex and changing outdoor environments, resulting in a high equipment failure rate. Therefore, improvements to the existing technology are necessary. Summary of the Invention

[0004] To improve the overall protection performance of existing technologies during application, this application provides an energy management system and control method for photovoltaic energy storage charging stations.

[0005] This application provides an energy management system and control method for a photovoltaic energy storage charging station, which adopts the following technical solution: it includes a box, a management module is fixedly installed inside the box, a telescopic mechanism is fixedly installed on the back of the box, protective mechanisms are fixedly installed on both sides of the outer end of the telescopic mechanism, heat dissipation slots are opened on both sides of the box, a dustproof net is fixedly installed inside the heat dissipation slots, the protective mechanism covers the outside of the dustproof net, and a sealing cover is installed on the front of the box by bolts;

[0006] The telescopic mechanism includes a heat-conducting base, on which piston sleeves are fixedly installed at the top and bottom of the middle part of the heat-conducting base. The piston sleeve is filled with liquid phase change material. A piston rod is slidably connected inside the piston sleeve. A connecting frame is fixedly installed at the outer end of the piston rod. The protective mechanism is fixedly installed at both ends of the connecting frame.

[0007] Optionally, the protective mechanism includes a trough and a cleaning module. The trough is located on both sides of the top and bottom of the box. The inner end of the trough penetrates the box. A sealing plate is slidably connected inside the trough. The sealing plate covers the inner side of the dustproof net. The outer side of the sealing plate is fixedly connected to the inner side of the connecting frame. A sealing plate is fixedly connected to the outer side of the sealing plate. The sealing plate covers the outer side of the trough.

[0008] Optionally, the cleaning module includes a slide block, which is fixedly installed on the outer end of the connecting frame. A rotating shaft is rotatably connected to the middle of the inner side of the slide block. A transmission group is fixedly connected to the inner side of the rotating shaft. A cleaning group is fixedly connected to the inner side of the transmission group. The inner side of the cleaning group and the outer side of the dustproof net are fitted together.

[0009] Optionally, the transmission assembly includes a fixed column and a gear. The fixed column is fixedly installed on the upper and lower ends of the outer side of the dustproof net. A rack is fixedly installed on the outer side of the fixed column. The gear is fixedly installed on the outer end of the rotating shaft. The gear and the rack are meshed together.

[0010] Optionally, the cleaning assembly includes a mounting frame, which is fixedly installed on the outer surface of the rotating shaft in a ring-shaped arrangement with equal intervals. The inner side of the mounting frame is fixedly connected with telescopic springs arranged linearly with equal intervals. The ends of the telescopic springs are fixedly connected with cleaning brush plates, and the brushes on the inner side of the cleaning brush plates are attached to the outer side of the dustproof net.

[0011] Optionally, the outer side of the cleaning brush plate is fixedly connected with support shafts at equal intervals, and the outer end of the support shaft passes through the mounting bracket.

[0012] Optionally, the front and rear ends of both sides of the housing are fixedly installed with support rails, and the two ends of the slide are fixedly connected with support sliders, which are slidably connected to the inner side of the support rails.

[0014] Optionally, mounting posts are fixedly installed at the four corners of the back of the box, and mounting frames are fixedly installed at the rear end of the mounting posts. Mounting holes are provided at the top center, bottom center, and both sides center of the mounting frame, and the mounting holes are countersunk holes.

[0015] A photovoltaic energy storage charging station energy management and control method includes the following steps:

[0016] Step 1: Equipment Integration and Installation: Within the energy management system enclosure, each component is fixedly installed according to its functional zones. The controller, MPLC module, and I / O module are installed in the main control area, connected via internal wiring. The MPLC module and I / O module serve as expansion units for the controller, used for signal processing and command output. Fuses, surge protectors, and circuit breakers are installed in the power line access area. Fuses and circuit breakers are connected in series in the power supply circuit, and surge protectors are connected in parallel at the main line inlet. Fiber optic boxes and switches are installed in the data transmission area. Fiber optic boxes have reserved fiber optic interfaces, and switches are connected to the controller and other communication equipment via network cables. Power modules are installed in an independent power supply area to provide stable power to each component, ensuring that the relative positions of each component meet electrical safety distance standards.

[0017] Step Two: Line Connection and Configuration. Connect the power module output to the fuse, surge protector, and circuit breaker to form the main power supply line; connect the circuit breaker output to the power supply interfaces of the controller, MPLC module, I / O module, switch, and other electrical equipment; use fiber optic cables to connect the fiber optic box to external data acquisition equipment and monitoring terminals to achieve remote data interaction; connect the switch to the controller, MPLC module, and I / O module via network cables to build an internal data communication network; after completing the line connection, configure basic parameters such as IP address and communication protocol for the controller, MPLC module, and switch to ensure normal data transmission between devices;

[0018] Step 3: Assemble the telescopic mechanism. Install a heat-conducting base on the back of the housing, using aluminum or copper to ensure thermal conductivity, and ensure it fits tightly against the back of the housing. Fix a piston sleeve at the top and bottom of the middle of the heat-conducting base, and fill the piston sleeve with Opteon™ SF33 or Vertrel™ XF liquid phase change material. Install the piston rod inside the piston sleeve, ensuring it can slide freely. Fix a connecting bracket to the outer end of the piston rod, and fix both ends of the connecting bracket to the protective mechanism to ensure a stable connection. This completes the overall assembly of the telescopic mechanism.

[0019] Step 4: Installation of the protection and cleaning mechanism. Grooves are cut into the top and bottom sides of the housing, penetrating the housing, and guide rails are installed inside. The sealing plate is fixedly connected to the inner side of the connecting frame, allowing the sealing plate to slide along the guide rails within the grooves and cover the inner side of the dustproof net. A sealing plate is fixed to the outer side of the sealing plate, ensuring the sealing plate covers the outer side of the groove. A slide block is installed at the outer end of the connecting frame, with support sliders installed at both ends of the slide block. The support sliders are slidably connected to the support rails on both sides of the housing. A rotating shaft is installed in the middle of the inner side of the slide block, with a gear fixed to the outer end of the rotating shaft. Fixed posts and racks are installed at the upper and lower ends of the outer side of the dustproof net, allowing the gear and rack to mesh. A transmission assembly and a cleaning assembly are installed at the inner end of the rotating shaft. The cleaning brush of the cleaning assembly is connected to the mounting frame via a telescopic spring, ensuring the cleaning brush bristles are in close contact with the outer side of the dustproof net.

[0020] Step 5: System initialization test. Connect the power supply and start the system. The controller uses the MPLC module and I / O module to detect the status of fuses, surge protectors, and circuit breakers to determine if there are any abnormalities such as short circuits, overloads, or surge protection device failures; it also detects the data transmission status between the switch and the fiber optic box to check if each communication link is working properly; it reads the initial position signals of the telescopic mechanism, protective mechanism, and cleaning module to confirm that they are in standby mode. If an abnormality is detected, a fault code is output through the display screen or communication port.

[0021] Step Six: Energy Monitoring and Data Acquisition. During system operation, the controller collects various data from the photovoltaic energy storage charging station in real time through the MPLC module and I / O module. This includes collecting the photovoltaic panel power generation, the charging and discharging status of the energy storage battery, and voltage and current parameters. It also receives power consumption data from the charging piles through the fiber optic box and switch. The controller monitors electrical equipment parameters such as fuse current, surge protector operating status, and circuit breaker opening and closing status. Simultaneously, a temperature sensor installed inside the enclosure transmits ambient temperature data to the controller, providing a basis for subsequent control.

[0022] Step 7: Temperature Adaptive Control. When the temperature data received by the controller shows that the external ambient temperature of the chamber rises to near or above the boiling point of the phase change material (33°C for Opteon™ SF33, 55°C for Vertrel™ XF), the heat-conducting seat transfers heat to the piston sleeve. The phase change material changes from a liquid to a gaseous state, and its volume expansion pushes the piston rod outward. The piston rod drives the connecting frame to move, and the connecting frame drives the sealing plate to be pulled out of the tank, opening the heat dissipation slot and dust filter, enhancing ventilation and heat dissipation inside the chamber. At the same time, the movement of the connecting frame drives the cleaning module to operate, and the cleaning brush moves in a circular motion around the rotating shaft to clean the dust on the surface of the dust filter. When the temperature drops below the boiling point of the phase change material, the phase change material condenses back into a liquid state, the piston rod retracts, the sealing plate reseals the heat dissipation slot, and the cleaning module resets.

[0023] Step 8: Intelligent control of power equipment. The controller intelligently controls fuses, surge protectors, and circuit breakers based on the collected power data. When an overload or short circuit is detected, the controller sends a command through the I / O module to control the circuit breaker to trip and disconnect the faulty circuit. The controller monitors the operating status of surge protectors in real time. If a lightning surge signal is detected, the surge protector is triggered to start protection, and the abnormal event is recorded. The controller continuously monitors the fuse current through the MPLC module. When the current exceeds the rated value, an early warning signal is issued to prompt maintenance personnel to check and replace the fuse.

[0024] Step Nine: Data Processing and Remote Communication. The controller analyzes and processes the collected data, performs data calculations and logical judgments through the MPLC module, generates energy management strategies, and uploads the processed data to the remote monitoring center through fiber optic boxes and switches. This supports remote real-time viewing of equipment operating status and historical data querying. The controller also receives control commands from the remote monitoring center, such as adjusting the charging and discharging strategies of the energy storage battery and controlling the start and stop of the charging pile, and executes the corresponding operations through the I / O module.

[0025] Step 10: Power Failure Protection and Emergency Handling. When a power failure is detected, the controller immediately activates the emergency program. On one hand, the temperature drop causes the phase change material to liquefy, and the piston rod retracts, causing the sealing plate to slide and seal the heat dissipation groove, preventing moisture from entering the enclosure. On the other hand, important data such as the remaining power of the energy storage battery and equipment operating parameters are saved through the I / O module. Simultaneously, the backup power supply is used to maintain the operation of the controller, MPLC module, and communication module for a short period of time, and the power failure information is sent to the remote monitoring center. After power is restored, the system automatically performs self-checks and data recovery to ensure normal equipment operation.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] This device utilizes the distinct boiling point characteristic of phase change materials. When the temperature reaches the phase change point, the material absorbs heat and vaporizes, pushing the piston rod to open the heat dissipation slots to enhance ventilation. The higher the temperature, the greater the degree of opening of the heat dissipation channels. When the temperature decreases, the material condenses and resets, closing the heat dissipation slots. Through the reversible characteristics of phase change materials, temperature-adaptive heat dissipation can be achieved without external power, avoiding the lag of traditional heat dissipation methods. It can automatically seal and protect against moisture when the equipment is powered off. At the same time, it is combined with aluminum or copper heat-conducting bases to significantly improve heat dissipation efficiency and further enhance its overall protective effect.

[0028] During operation, the protective mechanism activates for heat dissipation at high temperatures and forms a double seal with the sealing plate at low temperatures, isolating moisture and dust. When power is cut off and operation stops, the phase change material liquefies and automatically seals the heat dissipation tank to prevent moisture from corroding electronic components. The two phase change materials have strong chemical stability and can withstand a large number of phase change cycles. Combined with the cleaning module, the dustproof screen is automatically cleaned, enabling the enclosure to achieve a high level of protection and ensuring long-term stable operation of the equipment in complex outdoor environments. The phase change material-driven telescopic mechanism requires no electricity, saving energy compared to traditional electric temperature control devices. Opteon™ SF33 and Vertrel™ XF are non-toxic and environmentally friendly, harmless to humans and the environment. The equipment automatically adjusts its heat dissipation, sealing, and cleaning functions, reducing the frequency of manual maintenance and lowering maintenance costs, achieving the dual advantages of energy saving, environmental protection, and low-cost operation.

[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0039] This application discloses an energy management system and control method for a photovoltaic energy storage charging station. For example... Figure 1-8 As shown, the device includes a housing 1, a management module 2 fixedly installed inside the housing 1, a telescopic mechanism 3 fixedly installed on the back of the housing 1, protective mechanisms 6 fixedly installed on both sides of the outer end of the telescopic mechanism 3, heat dissipation slots 4 on both sides of the housing 1, a dustproof net 5 fixedly installed inside the heat dissipation slots 4, the protective mechanism 6 covering the outside of the dustproof net 5, and a sealing cover 7 installed on the front of the housing 1 by bolts.

[0040] The telescopic mechanism 3 includes a heat-conducting base 31. A piston sleeve 32 is fixedly installed at both the top and bottom of the heat-conducting base 31. The piston sleeve 32 is filled with a liquid phase change material. A piston rod 33 is slidably connected inside the piston sleeve 32. A connecting frame 34 is fixedly installed at the outer end of the piston rod 33. A protective mechanism 6 is fixedly installed at both ends of the connecting frame 34. During use, when the external ambient temperature of the housing 1 rises to near or above the boiling point of the liquid phase change material filled in the piston sleeve 32, the aluminum or copper heat-conducting base 31 conducts the heat generated by the operation of the management module 2 to the piston sleeve 32. The phase change material absorbs heat and changes from a liquid to a gas, expanding in volume and pushing the piston rod 33 outward. The piston rod 33 drives the outer connecting frame 34 to move, causing the sealing plates 63 in the protective mechanism 6 at both ends of the connecting frame 34 to be pulled out from the groove 61, opening the heat dissipation groove 4 and the dustproof net 5 to enhance ventilation inside the housing 1. Simultaneously, the connecting frame 34... The outer slide 621 slides along the support rail 6245 via the support slider 6246. The gear 6232 on the inner side of the slide 621 meshes with the rack 6233 on the outer side of the fixed column 6231, driving the rotating shaft 622 to rotate and make the cleaning brush 6243 move in a circular motion around the rotating shaft 622 to clean the dust on the surface of the dustproof net 5. When the ambient temperature drops below the boiling point of the phase change material, the gaseous phase change material condenses back to the liquid state, and the volume shrinks to form a negative pressure. The piston rod 33 retracts under the action of the pressure difference, driving the connecting frame 34 and the protective mechanism 6 to reset. The sealing plate 63 reseals the heat dissipation groove 4. The sealing plate 64 covers the groove body 61 to form a double-layer sealing structure. When the equipment is powered off, the temperature drops, and the phase change material liquefies, driving the sealing plate 63 to stably cover the inner side of the heat dissipation groove 4 to prevent moisture from corroding the internal electronic components. The whole process converts temperature changes into mechanical motion through the reversible phase change characteristics of the phase change material, realizing automatic control of heat dissipation, protection and cleaning.

[0041] The heat-conducting base 31 is made of thermally conductive aluminum or thermally conductive copper. The management module 2 is installed on the front of the heat-conducting base 31. The heat-conducting base 31 is used for efficient heat absorption and dissipation. The liquid phase change material can be Opteon™ SF33 or Vertrel™ XF. Opteon™ SF33 has a boiling point of 33°C. It changes from liquid to gas when the temperature is above 33°C and condenses back to liquid when the temperature is below this temperature. Vertrel™ XF has a boiling point of 55°C. It evaporates when the temperature is above 55°C and condenses when the temperature is below this temperature. The phase change process is reversible and stable. It has a high latent heat capacity and can achieve stable and rapid heat absorption and dissipation.

[0042] During the application of this device, a touch screen or control panel can be adapted to be installed on the sealing cover 7 to assist in operating the device.

[0043] Management module 2 consists of a controller, fuses, surge protectors, circuit breakers, fiber optic boxes, switches, power supplies, MPLC modules, and I / O modules. For specific details, please refer to the prior art section of the background art, as these are existing technologies and will not be elaborated upon here.

[0044] Please refer to Figures 1-8 The protective mechanism 6 includes a tank 61 and a cleaning module 62. The tank 61 is located on both sides of the top and bottom of the housing 1. The inner end of the tank 61 penetrates the housing 1. A sealing plate 63 is slidably connected inside the tank 61, covering the inner side of the dustproof net 5. The outer side of the sealing plate 63 is fixedly connected to the inner side of the connecting frame 34. A sealing plate 64 is fixedly connected to the outer side of the sealing plate 63, covering the outer side of the tank 61. The cleaning module 62 includes a slide 621, which is fixedly installed on the connecting frame. At the outer end of 34, a rotating shaft 622 is rotatably connected to the inner middle of the slide block 621. A transmission assembly 623 is fixedly connected to the inner side of the rotating shaft 622. A cleaning assembly 624 is fixedly connected to the inner side of the transmission assembly 623. The inner side of the cleaning assembly 624 is in close contact with the outer side of the dustproof net 5. This device uses a protective mechanism 6 and a cleaning module 62 working together. When the piston rod 33 of the telescopic mechanism 3 is driven by the phase change material to move the connecting frame 34 outward, the inner side of the connecting frame 34 drives the sealing plate 63 to slide along the guide rail 65 inside the groove 61, sealing the blockage. Plate 63 is pulled out from the tank 61 and covers the inside of the dustproof net 5. At the same time, the sealing plate 64 on the outside of the sealing plate 63 covers the outside of the tank 61, forming a double-layer sealing structure to prevent external moisture and dust from entering the inside of the box 1. During this process, the slide 621 fixed at the outer end of the connecting frame 34 slides along the support rail 6245 through the support slider 6246. The gear 6232 at the outer end of the inner rotating shaft 622 of the slide 621 meshes with the rack 6233 on the outer side of the fixed column 6231. As the connecting frame 34 moves, the gear 6232 meshes with the rack 6233 on the outer side of the fixed column 6231. The rolling motion on the piston rod 33 drives the rotating shaft 622 to rotate, which in turn drives the transmission assembly 623. The transmission assembly 623 drives the cleaning assembly 624 to operate, causing the cleaning brush 6243, which is attached to the outside of the dustproof net 5, to move in a circular motion around the rotating shaft 622, sweeping off the dust and debris attached to the surface of the dustproof net 5. When the piston rod 33 retracts due to the condensation of the phase change material, causing the connecting frame 34 to reset, the sealing plate 63 and the sealing plate 64 retract into the groove 61 to release the seal. The cleaning module 62 then stops working and waits for the next temperature change to trigger a new round of action.

[0045] Please refer to Figures 5-7The transmission assembly 623 includes a fixed column 6231 and a gear 6232. The fixed column 6231 is fixedly installed on the upper and lower ends of the outer side of the dustproof net 5. A rack 6233 is fixedly installed on the outer side of the fixed column 6231. The gear 6232 is fixedly installed on the outer end of the rotating shaft 622. The gear 6232 and the rack 6233 are meshed together. The cleaning assembly 624 includes a mounting bracket 6241. The mounting brackets 6241 are arranged in a ring at equal intervals and fixedly installed on the outer surface of the rotating shaft 622. The inner side of the mounting brackets 6241 is arranged in a linear pattern at equal intervals. A telescopic spring 6242 is fixedly connected to the column. A cleaning brush plate 6243 is fixedly connected to the end of the telescopic spring 6242. The brush on the inner side of the cleaning brush plate 6243 is attached to the outer side of the dustproof net 5. Support shafts 6244 are fixedly connected at equal intervals on the outer side of the cleaning brush plate 6243. The outer end of the support shaft 6244 passes through the mounting bracket 6241. During use, when the connecting bracket 34 moves under the action of the piston rod 33, the gear 6232 fixed to the outer end of the inner side of the sliding block 621 of the connecting bracket 34 rotates at the outer end of the shaft 622. The rack 6233, fixedly mounted on the upper and lower fixing posts 6231 on the outer side of the dustproof net 5, engages with the rack and rolls as the connecting frame 34 moves. The rolling of the gear 6232 drives the rotating shaft 622 to rotate, which in turn causes the mounting bracket 6241, which is fixed in a ring at equal intervals on the outer surface of the rotating shaft 622, to rotate as well. When the mounting bracket 6241 rotates, the linearly arranged telescopic springs 6242 on its inner side drive the cleaning brush plate 6243 to make a circular motion around the rotating shaft 622. The brushes on the inner side of the cleaning brush plate 6243 interact with the dustproof net 5. The outer side of the brush plate 6243 is attached to the surface of the dustproof net 5 to clean dust and debris. During the movement of the cleaning brush plate 6243, the telescopic spring 6242 can automatically adjust the pressure according to the unevenness of the surface of the dustproof net 5 to ensure that the brush is always in close contact with the dustproof net 5 and maintain the cleaning effect. The support shaft 6244 on the outer side of the cleaning brush plate 6243 passes through the mounting bracket 6241 and plays a limiting and guiding role to ensure that the cleaning brush plate 6243 remains stable during the circumferential movement and avoids deviation, thereby continuously and efficiently cleaning the dustproof net 5.

[0046] Please refer to Figures 3-4The box 1 has fixed support rails 6245 at both ends of its sides and front and rear. The slide block 621 has fixed sliders 6246 at both ends of its sides. The sliders 6246 are slidably connected to the inner side of the support rails 6245. The box 1 has fixed guide rails 65 at both ends of its sides. The sealing plate 63 is slidably connected to the inside of the guide rails 65. The box 1 has four fixed mounting posts 8 at its four corners on the back. The mounting frame 9 is fixedly installed at the rear end of the mounting posts 8. The mounting frame 9 has mounting holes 10 at the top center, bottom center, and both sides center. The mounting holes 10 are countersunk holes. During use, the fixed support rails 6245 at both ends of the box 1 and the sliders 6246 at both ends of the slide block 621 form a sliding guide structure. When the piston rod 33 of the telescopic mechanism 3 pushes the connecting frame 34 to move, the sliders 6246... The 6 slides inside the support rail 6245, providing stable guidance for the movement of the slide block 621 and the connecting frame 34, ensuring that the cleaning module 62 runs along the predetermined trajectory and avoiding deviation or shaking; the guide rails 65 at the front and rear ends of both sides of the box 1 provide sliding tracks for the sealing plate 63. When the connecting frame 34 drives the sealing plate 63 to move, the sealing plate 63 slides inside the guide rail 65, ensuring that it can accurately cover or remove the inside of the dustproof net 5, realizing the sealing and opening of the heat dissipation slot 4; the mounting columns 8 at the four corners on the back of the box 1 are used to install the mounting frame 9. The countersunk holes on the mounting frame 9 can be connected to the external mounting base through bolts. The countersunk hole design allows the bolt head to be embedded in the hole, ensuring that the surface is flat after installation, preventing the protrusion from affecting the installation and operation of the equipment, and ensuring that the entire box 1 is installed stably, so that the internal mechanisms remain stable during operation.

[0047] A photovoltaic energy storage charging station energy management and control method includes the following steps:

[0048] Step 1: Equipment Integration and Installation: Inside the energy management system enclosure 1, fix each component according to functional zones. Install the controller, MPLC module, and I / O module in the main control area, connecting them via internal wiring. The MPLC module and I / O module serve as expansion units for the controller, used for signal processing and command output. Fuses, surge protectors, and circuit breakers are installed in the power line access area. Fuses and circuit breakers are connected in series in the power supply circuit, and surge protectors are connected in parallel at the main line entrance. Fiber optic boxes and switches are installed in the data transmission area. Fiber optic boxes have reserved fiber optic interfaces, and switches are connected to the controller and other communication equipment via network cables. Power modules are installed in an independent power supply area to provide stable power to each component, ensuring that the relative positions of each component meet electrical safety distance standards.

[0049] Step Two: Line Connection and Configuration. Connect the power module output to the fuse, surge protector, and circuit breaker to form the main power supply line; connect the circuit breaker output to the power supply interfaces of the controller, MPLC module, I / O module, switch, and other electrical equipment; use fiber optic cables to connect the fiber optic box to external data acquisition equipment and monitoring terminals to achieve remote data interaction; connect the switch to the controller, MPLC module, and I / O module via network cables to build an internal data communication network; after completing the line connection, configure basic parameters such as IP address and communication protocol for the controller, MPLC module, and switch to ensure normal data transmission between devices;

[0050] Step 3: Assemble the telescopic mechanism 3. Install the heat-conducting seat 31 on the back of the housing 1. Select aluminum or copper heat-conducting seat 31 to ensure heat conduction performance and fit it tightly against the back of the housing 1. Fix the piston sleeve 32 at the top and bottom of the middle part of the heat-conducting seat 31 and fill the piston sleeve 32 with Opteon™ SF33 or Vertrel™ XF liquid phase change material. Install the piston rod 33 in the piston sleeve 32 to ensure that it can slide freely. Fix the connecting bracket 34 at the outer end of the piston rod 33. Fix the two ends of the connecting bracket 34 to the protective mechanism 6 to ensure a stable connection. The overall assembly of the telescopic mechanism 3 is completed.

[0051] Step 4: Installation of the protection and cleaning mechanism. Grooves 61 are made on both sides of the top and bottom of the housing 1, penetrating the housing 1. Guide rails 65 are installed inside. The sealing plate 63 is fixedly connected to the inner side of the connecting frame 34, allowing the sealing plate 63 to slide along the guide rails 65 within the groove 61 and cover the inner side of the dustproof net 5. A sealing plate 64 is fixed to the outer side of the sealing plate 63, ensuring that the sealing plate 64 covers the outer side of the groove 61. A slide block 621 is installed at the outer end of the connecting frame 34, and support sliders 6246 are installed at both ends of the slide block 621. The support sliders 6246 are then connected to… The support rails 6245 on both sides of the housing 1 are slidably connected; a rotating shaft 622 is installed in the middle of the inner side of the slide 621, and a gear 6232 is fixed at the outer end of the rotating shaft 622. Fixed columns 6231 are installed at the upper and lower ends of the outer side of the dustproof net 5 and a rack 6233 is provided so that the gear 6232 meshes with the rack 6233; a transmission group 623 and a cleaning group 624 are installed at the inner end of the rotating shaft 622. The cleaning brush plate 6243 of the cleaning group 624 is connected to the mounting bracket 6241 through a telescopic spring 6242 to ensure that the brush of the cleaning brush plate 6243 is in close contact with the outer side of the dustproof net 5.

[0052] Step 5: System initialization test. Connect the power supply and start the system. The controller uses the MPLC module and I / O module to detect the status of fuses, surge protectors, and circuit breakers to determine if there are any abnormalities such as short circuits, overloads, or surge protection device failures. It also detects the data transmission status between the switch and the fiber optic box and checks whether each communication link is working properly. The controller reads the initial position signals of the telescopic mechanism 3, the protective mechanism 6, and the cleaning module 62 to confirm that they are in standby mode. If an abnormality is detected, a fault code is output through the display screen or the communication port.

[0053] Step Six: Energy Monitoring and Data Acquisition. During system operation, the controller collects various data from the photovoltaic energy storage charging station in real time through the MPLC module and I / O module. This includes collecting the photovoltaic panel power generation, the charging and discharging status of the energy storage battery, and voltage and current parameters. It also receives power consumption data from the charging piles through the fiber optic box and switch. The controller monitors electrical equipment parameters such as fuse current, surge protector operating status, and circuit breaker opening and closing status. Simultaneously, the temperature sensor installed inside enclosure 1 transmits ambient temperature data to the controller, providing a basis for subsequent control.

[0054] Step 7: Temperature Adaptive Control. When the temperature data received by the controller shows that the external ambient temperature of the enclosure 1 rises to near or above the boiling point of the phase change material (33°C for Opteon™ SF33, 55°C for Vertrel™ XF), the heat-conducting seat 31 conducts heat to the piston sleeve 32. The phase change material changes from liquid to gas, and its volume expansion pushes the piston rod 33 to slide outward. The piston rod 33 drives the connecting frame 34 to move, and the connecting frame 34 drives the sealing plate 63 to be pulled out from the tank 61, opening the heat dissipation slot 4 and the dustproof net 5, enhancing the ventilation and heat dissipation inside the enclosure 1. At the same time, the movement of the connecting frame 34 drives the cleaning module 62 to operate, and the cleaning brush 6243 makes a circular motion around the rotating shaft 622 to clean the dust on the surface of the dustproof net 5. When the temperature drops below the boiling point of the phase change material, the phase change material condenses back to liquid, the piston rod 33 retracts, the sealing plate 63 reseals the heat dissipation slot 4, and the cleaning module 62 resets.

[0055] Step 8: Intelligent control of power equipment. The controller intelligently controls fuses, surge protectors, and circuit breakers based on the collected power data. When an overload or short circuit is detected, the controller sends a command through the I / O module to control the circuit breaker to trip and disconnect the faulty circuit. The controller monitors the operating status of surge protectors in real time. If a lightning surge signal is detected, the surge protector is triggered to start protection, and the abnormal event is recorded. The controller continuously monitors the fuse current through the MPLC module. When the current exceeds the rated value, an early warning signal is issued to prompt maintenance personnel to check and replace the fuse.

[0056] Step Nine: Data Processing and Remote Communication. The controller analyzes and processes the collected data, performs data calculations and logical judgments through the MPLC module, generates energy management strategies, and uploads the processed data to the remote monitoring center through fiber optic boxes and switches. This supports remote real-time viewing of equipment operating status and historical data querying. The controller also receives control commands from the remote monitoring center, such as adjusting the charging and discharging strategies of the energy storage battery and controlling the start and stop of the charging pile, and executes the corresponding operations through the I / O module.

[0057] Step 10: Power Failure Protection and Emergency Handling. When a power failure is detected, the controller immediately activates the emergency program. On one hand, the temperature drop causes the phase change material to liquefy, and the piston rod 33 retracts, causing the sealing plate 63 to slide, sealing the heat dissipation groove 4 and preventing moisture from entering the housing 1. On the other hand, important data such as the remaining power of the energy storage battery and equipment operating parameters are saved through the I / O module. At the same time, the backup power supply is used to maintain the operation of the controller, MPLC module, and communication module for a short period of time, and the power failure information is sent to the remote monitoring center. After the power supply is restored, the system automatically performs self-checks and data recovery to ensure the normal operation of the equipment.

[0058] The implementation principle of the photovoltaic energy storage charging station energy management system and control method in this application embodiment is as follows: The core component of the telescopic mechanism 3, the piston sleeve 32, is filled with Opteon™ SF33 or Vertrel™ XF liquid phase change material. The specific material can be selected according to the heat dissipation requirements. This material is not limited to the two mentioned above; other phase change materials can also be selected according to specific heat dissipation needs. During use, when the external ambient temperature of the housing 1 rises to near or above the boiling point of the phase change material (33°C for Opteon™ SF33 and 55°C for Vertrel™ XF), the thermal conductivity... The heat sink 31 is made of aluminum or copper and has high thermal conductivity, absorbing the heat generated during the operation of the management module 2. This heat is then transferred to the piston sleeve 32. The phase change material inside the piston sleeve 32 absorbs the heat conducted from the heat sink 31, changing from a liquid to a gaseous state through evaporation and heat absorption, further improving its heat dissipation efficiency. The expansion of the phase change material in its gaseous state also generates pressure, pushing the piston rod 33 inside the piston sleeve 32 outwards. The piston rod 33 moves the outer connecting bracket 34, thereby driving the protective mechanism 6 and the cleaning module 62 to operate, promoting the sealing... The blocking plate 63 is pulled out from inside the tank 61, at which point the heat dissipation slots 4 can be opened. Opening the heat dissipation slots 4 improves the ventilation effect inside the box 1. Simultaneously, during heat dissipation, the higher the temperature, the greater the expansion, allowing for better opening of the heat dissipation slots 4. The heat dissipation capacity can be adjusted in real time according to the temperature, improving the overall heat dissipation effect. When the ambient temperature drops below the boiling point of the phase change material, the gaseous phase change material rapidly condenses back to a liquid state, its volume shrinking to create negative pressure. The piston rod 33 retracts under the pressure difference, driving the connecting frame 34 and the protective mechanism 6. The entire process utilizes the phase change material... The reversible phase change characteristic directly converts changes in ambient temperature into mechanical motion, eliminating the need for an external power source and complex temperature control circuits. When the equipment is powered off, the temperature decreases, and the phase change material liquefies to seal both sides of the housing 1. At this time, the sealing plate 63 slides stably inside the guide rail 65, covering and sealing the inside of the heat dissipation groove 4, which improves the overall sealing effect. This allows the heat dissipation groove 4 to be automatically closed when the equipment stops running, ensuring that the housing 1 is in a sealed state. It can maintain a good sealing and protection effect when the equipment stops running and is powered off, preventing moisture from corroding electronic components when the equipment is not running.

[0059] During operation, when the piston rod 33 pushes the connecting frame 34, the connecting frame 34 can drive the sealing plate 63 to slide along the guide rail 65 within the groove 61. The sealing plate 63 can be pulled out of the groove 61 to open the heat dissipation groove 4 and the dustproof net 5. With the heat dissipation groove 4 fully open, rapid and efficient airflow can be achieved, improving its heat dissipation effect. During this period, when the equipment stops operating or the temperature drops, the gaseous phase change material liquefies. At this time, the piston rod 33 inside the piston sleeve 32 contracts due to the negative pressure created by the liquefaction, which in turn drives the connecting frame 34 to drive the sealing plate 63 to slide within the guide rail 65. The sealing plate 63 then seals the heat dissipation groove 4, and the sealing plate 64 covers the groove 61 to form a double-layer sealing structure, preventing moisture from entering the housing 1. During this process, during the sliding extension and retraction of the connecting frame 34, the slide block 621 at the outer end of the connecting frame 34 is supported by the slider 624. 6. Sliding along the support rail 6245, the gear 6232 at the outer end of the inner rotating shaft 622 of the slide block 621 meshes with the rack 6233 on the outer side of the fixed column 6231. As the connecting frame 34 moves, the gear 6232 rolls on the rack 6233 and drives the rotating shaft 622 to rotate, thereby driving the cleaning module 62 to run. The rotation of the rotating shaft 622 can drive the mounting frame 6241 to rotate around the rotating shaft 622, and the rotation of the mounting frame 6241 can drive the cleaning brush plate 6243 to rotate around the shaft 622. The rotating shaft 622 makes a circular motion, and the brush on the inner side of the cleaning brush plate 6243 is in contact with the outer side of the dustproof net 5 to sweep away dust and debris. The cleaning brush plate 6243 is connected to the mounting bracket 6241 through the telescopic spring 6242. During the cleaning process, the telescopic spring 6242 can provide elasticity at all times, so that the brush of the cleaning brush plate 6243 can be stably attached to the outer surface of the dustproof net 5, thus having a good cleaning function and ensuring its overall cleaning effect.

[0060] As can be seen, this device uses Opteon™ SF33 and Vertrel™ XF as phase change materials. Utilizing their well-defined boiling points and high latent heat capacity, it achieves precise temperature triggering and efficient heat exchange. When the ambient temperature reaches the boiling point of the phase change material, the material rapidly undergoes a phase change, absorbing a large amount of heat, effectively slowing down the rate of temperature rise inside the chamber 1. The precise temperature triggering mechanism ensures that the protective mechanism 6 activates the seal promptly at high temperatures and automatically disengages at low temperatures, avoiding problems of excessive or insufficient heat dissipation. Both phase change materials possess excellent chemical stability and long-term repeated phase change performance, capable of withstanding numerous phase change cycles with low performance degradation. In complex outdoor environments, the telescopic mechanism 3, thanks to the stable characteristics of the phase change materials, can operate reliably for extended periods without incident. The system ensures reliable operation of the protective mechanism 6 and the cleaning module 62. The double-layer sealing structure of the protective mechanism 6, combined with the dustproof net 5 and the automatic cleaning function of the cleaning module 62, gives the housing 1 a high level of protection, significantly improving the reliability of the equipment in extreme environments. The phase change material driven telescopic mechanism 3 requires no electricity, saving energy compared to traditional electric temperature control devices. At the same time, Opteon™ SF33 and Vertrel™ XF are both non-toxic and environmentally friendly materials with an ODP (ozone depletion potential) of 0 and a low GWP (global warming potential). They are harmless to humans and the environment after leakage, meeting environmental protection requirements. In addition, the automatic cleaning and sealing functions of the equipment reduce the frequency of manual maintenance and lower the overall operating cost.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
