[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Currently, low-voltage starting systems for both fuel-powered and electric electrical equipment generally face the challenge of insufficient adaptability to low-temperature environments. Traditional solutions mainly rely on lithium-ion batteries for power. Although lithium batteries have the advantage of high energy density, they have inherent defects under low-temperature conditions: the sharp decrease in lithium-ion migration rate directly leads to a significant reduction in the battery's maximum discharge current, resulting in poor starting performance. This problem makes it difficult for traditional starting power supplies to meet the instantaneous high-power demands of electrical equipment during startup under low-temperature conditions.

[0051] Based on this, see Figures 1 to 8As shown, this utility model embodiment provides a starting power supply device 10, which includes a housing structure 100, a capacitor module 200, and a battery module 300; the housing structure 100 has a first cavity 111 and a second cavity 112 inside, the first cavity 111 and the second cavity 112 being spaced apart; the capacitor module 200 is disposed in the first cavity 111; the battery module 300 is disposed in the second cavity 112, and the battery module 300 and the capacitor module 200 are connected in parallel; the capacitor module 200 is connected to an external circuit through the battery module 300.

[0052] In the starting power supply device 10 of this embodiment, by connecting the battery cell module 300 and the capacitor module 200 in parallel, the problem of insufficient adaptability of the starting system of the electrical equipment in low temperature environment is solved, thereby effectively improving the starting performance of the starting power supply device 10.

[0053] Compared to traditional lithium battery start-up power supplies, the start-up power supply device 10 of this embodiment can use a capacitor module 200 to assist the cell module 300 to provide a large current discharge effect under low temperature conditions. Under normal operating conditions, the cell module 300 can also be used alone to provide a large current, thus effectively improving the start-up performance of the start-up power supply device 10.

[0054] Specifically, the principle behind the discharge of capacitor module 200 at low temperatures is primarily based on its rapid charge-discharge capability and excellent low-temperature performance. The capacitor can quickly release a large current when needed, meeting the instantaneous high-power demands during low-temperature startup. Compared to lithium-ion batteries, capacitors exhibit less performance degradation at low temperatures. Lithium-ion batteries face a decrease in lithium-ion migration rate at low temperatures, leading to a significant reduction in discharge capacity. In contrast, capacitors, with their different charge storage mechanism, can maintain high discharge efficiency at lower temperatures. Furthermore, the parallel connection of capacitor module 200 and cell module 300 allows the capacitor to provide a large current assist during equipment startup, enhancing overall startup performance. Under normal operating conditions, cell module 300 can also provide a large current when operating alone.

[0055] Furthermore, the housing structure 100 of this embodiment separates the capacitor module 200 from the battery cell module 300, which helps reduce the risk of thermal runaway. Under high load conditions, the capacitor can effectively absorb instantaneous current fluctuations, ensuring the stability and safety of the system. In summary, the introduction of the capacitor module 200 enables the starting power supply device 10 to more effectively provide the high power required for starting under low temperature conditions, improving overall starting performance and the reliability of the electrical equipment.

[0056] Specifically, the capacitor module 200 includes a capacitor circuit board 210 and multiple capacitors 220. The multiple capacitors 220 are connected to the capacitor circuit board 210 and are connected in series. The capacitor circuit board 210 is connected in parallel with the cell module 300.

[0057] Specifically, the number of capacitors 220 can be one, two, or more, and there is no single limitation. By setting multiple capacitors 220 in series, the overall capacitance and voltage withstand capability of the capacitor module 200 can be increased, thereby enhancing its performance in high-current discharge scenarios. In addition, the design of multiple capacitors 220 in series can effectively distribute the current load, reduce the working pressure of a single capacitor 220, and extend its service life. The capacitors 220 are integrated into the capacitor circuit board 210 by welding to form a module. This welding connection method not only ensures the reliability of the electrical connection but also improves the overall structural strength and shock resistance of the module.

[0058] The capacitor circuit board 210 is connected in parallel with the battery cell module 300. This design allows the capacitor module 200 to provide instantaneous high-power assistance when the device starts up, while under normal operating conditions, the battery cell module 300 can operate independently and provide a stable high-current output. Through this parallel connection, the starting performance of the starting power supply device 10 is significantly improved. Especially under low-temperature conditions, the rapid charging and discharging capability and excellent low-temperature performance of the capacitor module 200 can effectively compensate for the reduced discharge capacity of the lithium battery in low-temperature environments.

[0059] In a preferred embodiment, capacitor 220 may be a supercapacitor. Supercapacitors possess excellent energy storage capacity and rapid charge / discharge characteristics, exhibiting higher energy density and power density compared to traditional capacitors. Their operating principle primarily relies on the formation of an electrical double layer between the electrodes and the electrolyte, enabling the storage and release of large amounts of electrical energy within a rapid timeframe, making them suitable for applications requiring frequent charge / discharge. By selecting a supercapacitor as capacitor 220, the response speed of the starting power supply device 10 can be significantly improved. Especially in starting applications with high instantaneous current demands, supercapacitors provide excellent support, enabling the rapid fulfillment of instantaneous current requirements during startup.

[0060] See Figure 4 As shown, in one embodiment, the capacitor module 200 further includes a current-carrying connector 230, which is disposed between the capacitor circuit board 210 and a plurality of capacitors 220. There are multiple current-carrying connectors 230, and the plurality of capacitors 220 are connected in series through the current-carrying connectors 230.

[0061] The current-carrying connector 230 is independent of the capacitor circuit board 210. Multiple capacitors 220 are connected together through the current-carrying connector 230. This design not only realizes the series connection of multiple capacitors 220, but also improves the heat dissipation of the capacitor module 200. In some embodiments, the current-carrying connector 230 can be made of a high thermal conductivity material, which can effectively conduct the heat generated by the capacitors 220 during operation and avoid performance degradation or damage caused by heat accumulation. In addition, the independent setting of the current-carrying connector 230 also facilitates the installation and maintenance of the capacitors 220, improving the overall reliability and service life of the module.

[0062] Through this design, the capacitor module 200 can maintain stable performance under high load operating conditions, further enhancing the startup performance and safety of the startup power supply device 10. Specifically, the number of current-carrying connecting pieces 230 can be one, two, or more, and is not limited to a single number.

[0063] It should also be noted that two adjacent capacitors 220 can be connected via at least one current-carrying connector 230, or two adjacent capacitors 220 can be connected via multiple current-carrying connectors 230, depending on the design requirements of the capacitors 220. In actual design, the number of current-carrying connectors 230 can be selected according to the system's power requirements, heat dissipation requirements, and current carrying capacity to ensure the optimal performance of the capacitor module.

[0064] Specifically, when two adjacent capacitors 220 are connected via a current-carrying connector 230, this simplified configuration is suitable for applications with low power requirements, adequately meeting basic current transfer needs. In this case, the current-carrying connector 230 has a relatively light workload, simplifying the overall structure and helping to reduce production costs and installation complexity. However, this configuration may face insufficient heat dissipation under high load conditions and should therefore be used under low current density conditions.

[0065] On the other hand, when adjacent capacitors 220 are connected through multiple current-carrying connectors 230, this configuration can significantly improve current transfer capability and heat dissipation efficiency. The parallel design of multiple current-carrying connectors 230 can effectively distribute the current load, reduce heat buildup on individual current-carrying connectors 230, and minimize the risk of performance degradation due to heat accumulation. This design is ideal for high-load and high-power applications, such as high-power startup equipment or applications requiring frequent high-current charging and discharging. Therefore, by appropriately selecting the number of current-carrying connectors 230, the supercapacitor module can exhibit more stable electrical performance under various operating conditions.

[0066] Specifically, the current-carrying connector 230 is designed to include a connector body 231 and a connector 232. The function of the connector body 231 is to realize current transmission. Specifically, the connector body 231 is configured to be connected in series with two connected capacitors 220, thereby forming a series circuit. This design can effectively improve the efficiency of current transmission and ensure that the capacitors 220 have good electrical connection performance during operation.

[0067] In one embodiment, the connector 232 is made of an insulating material, such as plastic or other synthetic insulating material, and is responsible for fixing the sheet body 231 to the capacitor circuit board 210, so that electrical connection and mechanical fixation complement each other. Specifically, the design of the connector 232 takes into account the stability and safety of the electrical connection, and therefore can preferably be an insulating rivet. By providing an insulating coating layer on the outer layer of the rivet, the connector 232 can achieve a stable connection between the current-carrying connecting sheet 230 and the circuit board 210, while ensuring good insulation between the connector itself and the connecting sheet and the circuit board. This design not only improves the safety of the electrical connection and avoids the risk of short circuit or current leakage, but also enhances the structural stability of the entire capacitor module 200.

[0068] When the current-carrying circuit is designed as a current-carrying connecting piece 230 independent of the capacitor circuit board 210, holes can be drilled in the piece body 231 and the capacitor circuit board 210 to securely fix the connector 232 to the capacitor circuit board 210. This fixing method can effectively reduce electrical interference and improve circuit stability. Meanwhile, the connection between the capacitor 220 and the capacitor circuit board 210 is achieved by soldering, with the signal acquisition circuit board 313 soldered to the corresponding position, thereby realizing effective voltage signal acquisition. This soldering method ensures signal reliability and real-time performance, helps to monitor the operating status of the capacitor 220 in real time, and provides necessary data support.

[0069] The materials and structural design used in the current-carrying connector 230 play a crucial role in improving circuit performance. The connector body 231 is typically made of a highly conductive metal, such as copper or aluminum, to optimize current transmission efficiency and reduce power consumption. Simultaneously, selecting a suitable insulating material, such as plastic, as the connector 232 prevents current leakage and short-circuit risks, thereby improving the overall system safety.

[0070] It should be noted that leads refer to electrical connections, encompassing a wide range of applications, including but not limited to the transmission of current and control signals. The design and implementation of leads are crucial to the performance of the entire electrical system, and their selection must consider physical structure, material properties, and application requirements. In implementing leads, various methods are typically employed, including copper foil on the circuit board and external wires.

[0071] In circuit board design, copper foil is a common form of conductor. The advantage of using copper foil as a conductor is that it provides a low-resistance transmission path, effectively reducing energy loss and improving the overall system efficiency. Copper foil can be arranged on different layers of the circuit board to form a multi-layer circuit board structure, depending on the design requirements. By properly designing the width and thickness of the copper foil, current transmission capacity and the circuit's thermal management performance can be optimized. Furthermore, using copper foil on the circuit board reduces the need for external connectors, thereby lowering production costs and assembly complexity.

[0072] On the other hand, external wires are also one of the main methods for achieving lead connection. External wires typically use cables or wire materials of different specifications, such as tinned copper wire, aluminum wire, etc. The advantage of using external wires lies in their flexibility, making them suitable for situations requiring the connection of different components and modules.

[0073] Choosing the appropriate connection method is crucial in the design of leads. Connection methods include soldering, plugging, and crimping, each with its own unique advantages and disadvantages. Soldering provides a stable electrical connection, suitable for long-term fixed connection requirements; while plugging facilitates maintenance and disassembly, suitable for equipment requiring frequent replacement or repair. When selecting a connection method, not only electrical performance should be considered, but also mechanical strength, applicable scenarios, and ease of maintenance, to ensure the overall reliability and stability of the lead.

[0074] Furthermore, at least one surface of the body 231 is recessed with a relief groove 2311. This design not only improves the compactness of the device but also enhances its structural durability. The presence of the relief groove 2311 allows at least a partial receptacle within the groove at one end of the connector 232 away from the capacitor circuit board 210. When the end of the connector 232 is received within the relief groove 2311, the overall thickness of the current-carrying connector 230 can be significantly reduced, thereby optimizing the space utilization of the device. This compact design is particularly suitable for applications with strict space requirements, such as electronic devices with limited circuit board layout.

[0075] Furthermore, the design of the clearance groove 2311 is not only for improving space efficiency, but also for its important protective function. It effectively provides physical protection for the end of the connector 232, preventing damage from external bumps or impacts. This protection is particularly important during transportation and installation, significantly reducing the risk of equipment failure caused by external forces, thereby improving the overall system reliability and service life.

[0076] Specifically, connector 232 can be a rivet, a choice with many advantages. Rivets are fasteners widely used in mechanical connections, typically made of metal, and possess good strength and durability. Their advantage lies in providing a secure and durable connection, especially suitable for environments requiring resistance to vibration or shock. Furthermore, rivets are relatively easy to install, usually requiring only impact or pressure to secure them, facilitating efficient production and assembly.

[0077] Another important feature of rivets is their ability to adapt well to different material combinations, such as the connection of metals and plastics, which is especially important for the application scenarios of connector 232. In the connection between the chip body 231 and the circuit board 210, rivets can effectively and firmly fix the components together, avoiding loosening and poor contact, thereby ensuring stable current transmission.

[0078] In addition, when rivets are selected as the connection method for connector 232, their design versatility can be further utilized for optimization. For example, different types and specifications of rivets, such as flat-head rivets, semi-circular rivets, or fastening screws, can be selected according to actual needs to meet specific load-bearing capacity and aesthetic requirements. This flexibility allows the equipment to more effectively achieve structural optimization and performance improvement in different application scenarios.

[0079] At the same time, the choice of rivets can also improve the overall static strength of the current-carrying connecting piece 230, because the rivets form a tight joint surface after assembly, which helps to improve the impact resistance of the device and reduce the potential risk of damage caused by external forces. In addition, the implementation of rivets can also reduce additional machining steps, making the production process more efficient and economical.

[0080] Furthermore, see Figure 5 As shown, the capacitor module 200 also includes a heat sink 240, which is connected to the capacitor circuit board 210. The heat sink 240 is positioned corresponding to at least a portion of the copper foil connecting two adjacent capacitors 220 in the capacitor circuit board 210. This design, through the rational layout of the heat sink 240, effectively improves the heat dissipation performance of the capacitor circuit board 210, thereby ensuring that the capacitors 220 maintain good thermal management during operation and preventing performance degradation or damage due to overheating.

[0081] The principle behind the heat sink 240 is to increase the heat conduction path, thereby efficiently guiding the heat generated by the copper foil in the capacitor circuit board 210 to the heat sink 240. As an important electronic connection material in the capacitor circuit board 210, the copper foil typically generates heat during operation, especially under high load conditions. In this case, the heat sink 240 provides additional heat dissipation, thereby reducing the circuit board temperature. Furthermore, the layout of the heat sink 240 can be adjusted according to actual design requirements to be as close as possible to the heat-generating copper foil, enhancing its heat dissipation efficiency.

[0082] In terms of specific implementation, the heat sink 240 can be made of various materials, such as aluminum alloy, copper, or other alloy materials with good thermal conductivity, to improve heat dissipation. Furthermore, the shape and structure of the heat sink 240 can be designed as heat dissipation fins to increase the contact area with air and further promote heat dissipation. Specifically, the structural design of the heat sink 240 can include multiple heat dissipation fins. The number of these fins can be one, two, or more; there is no single limitation. Setting multiple heat dissipation fins can significantly improve heat dissipation efficiency and ensure effective heat management in various usage scenarios.

[0083] Through this design, the heat sink 240 not only effectively dissipates heat from the copper foil in the capacitor circuit board 210, but also contributes to the overall stability and safety of the module. When the heat sink 240 dissipates heat effectively, it can prevent the capacitor 220 from degrading or burning out due to high temperatures, thereby improving the reliability and lifespan of the module.

[0084] See Figure 5 As shown, in another embodiment, compared to the above embodiment, capacitor 220 can be directly soldered and fixed to capacitor circuit board 210. This design choice has significant technical advantages and can effectively optimize the connection method of capacitor.

[0085] By directly soldering, a robust mechanical and electrical connection is formed between capacitor 220 and capacitor circuit board 210. The solder joint provides high conductivity, thereby improving the efficiency of power transmission and making the overall circuit performance more reliable. In addition, direct soldering also enables smaller component footprint, which helps to improve circuit integration and meet the requirements for high power density and miniaturized design.

[0086] See Figure 6 As shown, in one embodiment, the first cavity 111 includes a plurality of mounting holes 1111, which are spaced apart, and a plurality of capacitors 220 are disposed in the mounting holes 1111 in a corresponding manner.

[0087] In this process, the separate mounting holes 1111 allow each capacitor 220 to be individually fixed in its specific position, facilitating precise positioning of multiple capacitors 220 and thus ensuring the assembly accuracy of the overall module.

[0088] Firstly, by independently placing capacitors 220 in multiple mounting holes 1111, the effects of heat conduction and convection between them can be effectively reduced. Especially under high-intensity operating conditions, multiple capacitors 220 will generate a certain amount of heat during charging and discharging. By isolating them, the mutual thermal influence caused by temperature accumulation between multiple sets of capacitors is reduced, thereby ensuring that each capacitor 220 can operate in a better temperature environment and extending its service life.

[0089] Furthermore, the presence of multiple mounting holes 1111 significantly improves the strength of the housing structure 100. Each mounting hole 1111 not only provides fixed support for the capacitor 220 but also physically disperses external stresses acting on the housing structure 100, preventing deformation or structural damage caused by pressure concentration. Due to this design, the housing structure 100 can remain stable in higher operating environments, improving the reliability of the capacitor module 200. Specifically, the number of mounting holes 1111 can be one, two, or more, depending on the actual needs and design requirements of the capacitor 220, and is not limited to a single number here.

[0090] Specifically, see Figure 2 and Figure 7 As shown, the battery module 300 includes a battery management module 310 and a battery cell assembly 320. The battery management module 310 includes a battery management circuit board 311 and a connecting structure 312. The battery cell assembly 320 is disposed in the second cavity 112, and the battery cell assembly 320 and the capacitor module 200 are connected in parallel through the connecting structure 312, and the connecting structure 312 is electrically connected to the battery management module 310.

[0091] The battery management circuit board 311 integrates a battery management chip, which can monitor and control the discharge process of the cell assembly 320 in real time. By monitoring parameters such as voltage, current, and temperature of the cell assembly 320, it dynamically adjusts the discharge strategy to ensure the safe use and maximized performance of the start-up power supply device 10. Furthermore, in some embodiments, the battery management module 310 can also control the output circuits of the cell module 300 and the capacitor module 200. This integrated management solution enables optimized control of the entire power system, including the selection of charging and discharging timings and the design of energy distribution strategies, thereby effectively improving the overall efficiency of the power system.

[0092] The wiring design of the lead structure 312 within the housing structure 100 simplifies the connection between the capacitor module 200 and the cell module 300, while also making the internal structure of the entire startup power supply device 10 more compact. This compact design not only saves space but also reduces interference between lines, improving the overall stability and reliability of the system. In specific implementations, the lead structure 312 can take the form of a flexible circuit board or metal conductor wires, which offers the advantage of flexibly adapting to different spatial layout requirements, making it particularly suitable for connecting different components within the power module, thereby effectively improving design flexibility.

[0093] The placement of the cell assembly 320 fully utilizes the space of the second cavity 112, thereby optimizing the size and shape design of the power module. Typically, the cell assembly 320 may include multiple individual battery cells; the specific number can be one, two, or more, and is not limited to a single number. By incorporating multiple battery cells, not only can the energy density of the entire cell assembly 320 be increased, but redundant design can also be achieved, improving the reliability and safety of the system.

[0094] In one embodiment, the lead structure 312 is designed to include a busbar and terminals. The busbar is used to electrically connect to the battery cell assembly 320 and the capacitor module 200, respectively, thereby achieving efficient power transfer. By integrating the outputs of the battery cell module 300 and the capacitor module 200, the busbar ensures that the required current can be provided as needed during discharge, improving the response speed and performance stability of the entire start-up power supply device 10.

[0095] The terminal block connects to the busbar, and its main function is to provide a stable electrical connection for conducting electrical energy to external circuits. This design not only improves current conduction efficiency but also reduces system resistance losses, thereby ensuring the high efficiency and reliability of the power supply unit. Specifically, the connection between the terminal block and the busbar can be achieved through welding, mechanical fixing, etc. Choosing a suitable connection method helps improve conductivity and mechanical strength.

[0096] The housing structure 100 has a connection hole 121, and the terminal passes through the connection hole 121. The design of the connection hole 121 allows the terminal to be easily connected to an external circuit. In this way, users can easily connect to the power system, and it also provides convenience for subsequent maintenance and upgrades.

[0097] In terms of implementation, the busbar of the lead structure 312 can be made of metals with good conductivity, such as copper or aluminum, to improve overall conductivity and durability. The number of terminals can be flexibly configured according to specific design requirements; specifically, there can be one, two, or more terminals, with no single limitation. Multiple terminals can effectively distribute the current load and improve system safety. Furthermore, when the system requires increased current output or the addition of external devices, the multiple terminal design allows for greater flexibility in adapting to different application scenarios.

[0098] Specifically, the busbar includes a positive busbar 3123 and a negative busbar 3124. The positive busbar 3123 is electrically connected to the positive terminals of both the battery cell assembly 320 and the capacitor module 200, forming a stable positive conductive path. The negative busbar 3124 similarly serves to electrically connect the negative terminals of the battery cell assembly 320 and the capacitor module 200. This design ensures that the current can flow rapidly between the battery cell assembly 320 and the capacitor module 200, effectively meeting the system's energy requirements.

[0099] In power systems, a well-designed busbar structure can significantly reduce resistance, improve current transmission efficiency, and reduce energy loss. Therefore, the configuration of the positive busbar 3123 and the negative busbar 3124 for the positive and negative terminals, respectively, not only fully utilizes the characteristics of the battery and capacitor but also integrates their functions to ensure a fast and efficient response to load changes.

[0100] The terminals include a positive terminal 3121 and a negative terminal 3122. The positive terminal 3121 is connected to the positive bus 3123 to deliver current from the positive bus to the external circuit, while the negative terminal 3122 is connected to the negative bus 3124 to output negative current to the external load. This configuration provides a stable electrical connection, thus improving the overall performance of the power supply system.

[0101] Two connection holes 121 are provided, one for the positive terminal 3121 and the other for the negative terminal 3122. The purpose of having two connection holes 121 is to provide an independent channel for each terminal. This design makes the current output path clearer, thereby reducing the risk of short circuits and signal interference. Furthermore, parameters such as the diameter and length of the terminals can be optimized according to actual design requirements to achieve good mechanical strength and electrical contact performance; no single limitation is imposed here.

[0102] Specifically, capacitor 220 includes a positive terminal block 221 and a negative terminal block 222. The battery cell assembly 320 is similarly structured, including a positive terminal block 321 and a negative terminal block 322. Specifically, the positive terminal block 221 and the positive terminal block 322 are connected to the positive busbar 3123, and the negative terminal block 222 and the negative terminal block 322 are connected to the negative busbar 3124. This connection method ensures the stability and efficiency of the power system and promotes the effective transmission of electrical energy.

[0103] In this embodiment, the positive terminal busbar 221 of the capacitor and the positive terminal busbar 321 of the battery cell are connected by the positive terminal busbar 3123, enabling the starting power supply device 10 to efficiently and reliably output positive current through this busbar. Furthermore, the design of the negative terminal busbar 3124 effectively connects the negative terminal busbar 222 of the capacitor and the negative terminal busbar 322 of the battery cell, ensuring that the starting power supply device 10 outputs negative current through the negative terminal busbar. This configuration not only improves the overall current capability of the system but also ensures that the system can continuously and stably provide current during rapid discharge or high-load applications.

[0104] In practical implementation, the materials for the positive busbar 3123 and the negative busbar 3124 can be metals with excellent conductivity, such as copper or aluminum. This not only improves conductivity efficiency but also effectively reduces heat generation and extends the service life of the equipment. Furthermore, in actual design requirements, the busbar configuration can be set to single or multiple rows to adapt to different current load requirements. For example, when higher current output is required, multiple capacitor positive busbars 221 and battery cell positive busbars 321 can be used; the specific number is not limited. This design improves the adaptability of the starting power supply device 10 to dynamic load changes, ensuring stable system performance under various operating environments.

[0105] In one embodiment, the cell module 300 further includes a signal acquisition circuit board 313. The signal acquisition circuit board 313 can monitor the voltage of the cell assembly 320 in real time, thereby ensuring that the battery system operates in a safe working state. As the core component of the power system, the voltage state of the cell assembly 320 directly affects the performance and safety of the device; therefore, voltage monitoring is crucial.

[0106] The signal acquisition circuit board 313, through its electrical connection with the battery cell assembly 320, can acquire real-time voltage data of the battery cell assembly 320. This data can promptly reflect the charging status, discharging status, and health status of the battery cell, thereby providing users with accurate battery usage information. Simultaneously, this monitoring system can predict potential battery cell failures through data analysis, reducing potential risks.

[0107] In addition to monitoring the battery cell assembly 320, the signal acquisition circuit board 313 can also be connected to the battery management module 310. Through this connection, the overall voltage of the starting power supply device 10 can be monitored. The battery management module 310 is a core module for managing and controlling the battery, and its functions include, but are not limited to, battery charge and discharge control, overcharge and over-discharge protection. The voltage monitoring of the battery management module 310 by the signal acquisition circuit board 313 can comprehensively improve the safety and reliability of the power system, ensuring that the voltage remains within a reasonable range during operation.

[0108] In specific implementations, the signal acquisition circuit board 313 can be designed with different circuit topologies, such as differential signal acquisition technology or single-ended signal acquisition technology, to meet the requirements of different voltage measurement accuracies. Differential signal acquisition technology can effectively reduce the influence of interference signals on the measurement results and improve measurement accuracy. Single-ended signal acquisition technology, on the other hand, has advantages in cost and simplicity. The specific acquisition method chosen can be rationally configured according to the application requirements of the power supply system to ensure that the signal acquisition circuit board 313 can operate stably in a specific environment.

[0109] Furthermore, the signal acquisition circuit board 313 can integrate certain processing capabilities, such as a microcontroller or application-specific integrated circuit (ASIC), to perform preliminary processing and analysis of the acquired data. This design not only improves the system's response speed but also enables local fault diagnosis, thereby reducing reliance on external monitoring equipment.

[0110] Further, see Figure 7 As shown, the power supply device 10 also includes a leakage detection component 400, which is connected to the cell module 300 and / or the capacitor module 200. The leakage detection component 400 is disposed inside the housing structure 100 and is configured to detect electrolyte contact inside the housing structure 100 and output a control signal.

[0111] The main function of the leakage detection component 400 is to monitor in real time whether there is any leakage of electrolyte inside the housing structure 100. When internal electrolyte leakage occurs, the leakage detection component 400 can detect the presence of liquid and immediately output a control signal. This control signal can drive the battery management module 310 or other controllers to take corresponding protective measures, such as cutting off the power supply, issuing an alarm, or activating the ventilation system, to prevent further damage.

[0112] This detection mechanism significantly improves the safety of the starting power supply unit 10. In the event of a liquid leak, the electrolyte may cause a short circuit or other electrical faults, and in severe cases, even a fire. Therefore, the timely response of the leak detection component 400 effectively reduces this risk, protecting the normal operation and safe use of the equipment.

[0113] Specifically, when the leakage detection component 400 is connected to the cell module 300, the signal output by the leakage detection component 400 can be quickly transmitted to the cell module 300, and necessary corresponding control can be performed through the battery management circuit board 311. This design provides an effective monitoring and response mechanism for the power supply device 10, enabling timely preventive measures to be taken when an electrolyte leakage event occurs. In addition, as the core control unit of the cell module 300, the battery management circuit board 311 has rapid processing and response capabilities, ensuring that it can immediately perform protective operations such as cutting off the power or issuing an alarm after receiving a leakage detection signal, to prevent potential risks to the equipment caused by leakage, such as short circuits or equipment damage.

[0114] In some embodiments, the leakage detection component 400 can also be connected to the capacitor module 200, and the output signal can also be transmitted through the capacitor circuit board 210 of the capacitor module 200. This design provides a more flexible monitoring solution, enabling the capacitor module 200 to play a greater role in protection, especially in high-load applications where damage caused by electrolyte leakage to capacitors is not negligible. By connecting to the capacitor module 200, the leakage detection component 400 can comprehensively monitor and control the electrolyte status throughout the entire power system.

[0115] It should be noted that regardless of the connection method between the leakage detection component 400 and the cell module 300 and / or capacitor module 200, leakage detection can be performed on the space within the housing structure 100. This ensures that the system can achieve real-time monitoring and management of electrolyte leakage in any configuration. Whether using the cell module 300 or the capacitor module 200 monitoring method, the overall safety of the starting power supply device 10 can be effectively improved, ensuring the stable operation of the user's equipment in various working environments.

[0116] See Figure 7 and Figure 8 As shown, in one embodiment, the leakage detection assembly 400 includes at least two detection elements 410, wherein the two detection elements 410 are arranged at intervals and the detection elements 410 are used to contact the electrolyte.

[0117] First, by setting multiple detection elements 410, the leakage detection assembly 400 can significantly expand its detection range. A single detection element 410 may fail to detect a leak in time due to limitations in its location. However, with at least two detection elements 410, even if one detection element 410 cannot detect a leak in time due to its location, the other detection elements 410 can still complete the monitoring within their effective range, thereby ensuring the safety of the entire power supply unit 10. Specifically, the number of detection elements 410 can be two, three, or four or more; there is no single limitation.

[0118] Secondly, the interconnectedness of multiple detection elements 410 improves the accuracy of the entire leak detection system. The detection elements 410 can be arranged in adjacent or combined structures to form a redundant monitoring mechanism. While one detection element 410 detects an electrolyte leak signal, other detection elements 410 can perform further verification, thereby eliminating the possibility of false alarms or missed alarms. This redundant design significantly improves the reliability of leak detection and reduces misjudgments caused by environmental or other factors.

[0119] Specifically, the detection component 410 includes a connecting piece 411 and a detection array 412. The detection array 412 is located at the bottom of the housing structure 100. The connecting piece 411 is connected to the detection array 412, the battery cell module 300, and / or the capacitor module 200, forming an electrical circuit in the leakage detection assembly 400. This design enables the leakage detection assembly 400 to quickly sense and react when liquid comes into contact with it.

[0120] When electrolyte, external liquid, or impurities enter the housing structure 100, the detection pin 412 will become electrically conductive. Based on this change, the connecting piece 411 can collect the circuit's conduction signal in real time. The collection of this signal enables the leakage detection component 400 to efficiently and promptly determine whether there is liquid inside the housing, thereby achieving an effective detection purpose.

[0121] In this embodiment, the connecting piece 411 serves as a connecting carrier connected to the detection row 412, and is connected to the cell module 300 and / or the capacitor module 200 respectively, so as to realize the detection function of the detection element 410 through current changes. The design of the connecting piece 411 not only acts as a bridge for signal transmission, but also plays a crucial role in leakage detection.

[0122] When the connecting piece 411 is connected to the cell module 300, it is electrically connected to the battery management circuit board 311, enabling rapid response through the circuit board. The advantage of this design is that the battery management circuit board 311 possesses efficient data processing and response capabilities, allowing it to promptly receive current change signals from the connecting piece 411 and take appropriate control measures for potential leaks. Thus, upon detecting electrolyte leakage, the battery management circuit board 311 can quickly cut off the power supply or issue an alarm, thereby ensuring the safe operation of the entire power supply unit 10.

[0123] Furthermore, when the connecting piece 411 is connected to the capacitor module 200, current can also be fed back through the capacitor circuit board 210. Through this design, the electrical characteristics of the capacitor module 200 are integrated, and the connecting piece 411 can quickly feed back the electrolyte signal to the capacitor circuit board 210 after receiving it, realizing a multi-level monitoring and response mechanism.

[0124] Specifically, the detection busbar 412 can be made of aluminum, whose lightweight and good electrical conductivity make it an ideal choice for manufacturing detection busbars. Aluminum's corrosion resistance also effectively extends the service life of the detection busbar, ensuring it is not easily damaged in electrolyte-permeable environments. Furthermore, the flat and uniform surface of the aluminum busbar ensures good liquid contact, promoting accurate leak detection.

[0125] The connector 411 can be made of nickel sheet, which exhibits excellent conductivity and corrosion resistance, making it suitable for electrical connections. The strength and durability of nickel sheet allow it to withstand frequent electrical connections and disconnections without easily leading to increased contact resistance or poor contact. This material choice enhances the reliability of the entire leak detection system, ensuring timely feedback in critical situations.

[0126] Furthermore, by adopting a design where the detection pin 412 is in direct contact with the liquid, corrosion of the connecting piece 411 by the liquid can be effectively avoided, thereby reducing the risk of open circuits caused by liquid damage to the connecting piece 411. The implementation of this design in the leak detection assembly 400 will significantly improve the reliability and stability of the system.

[0127] Specifically, the detection pin 412 is in direct contact with the liquid, enabling rapid detection of the presence of electrolyte or external liquids. Since the detection pin 412 is made of aluminum, the corrosion resistance of aluminum can reduce the damage caused by liquids to the material to a certain extent. When liquid enters the housing structure 100, the conductivity of the liquid allows the detection pin 412 to achieve electrical continuity. This continuity signal is transmitted to the connecting piece 411, thus achieving a rapid response to the presence of liquid. The main function of the connecting piece 411 is signal transmission; therefore, avoiding direct contact with the liquid helps maintain the integrity of its surface and interior, reduces contact resistance, and ensures the accuracy and timeliness of signal transmission. Preventing the intrusion of corrosive liquids not only extends the service life of the connecting piece 411 but also improves the reliability of the entire detection system.

[0128] This design not only reduces the response time of the leakage detection component 400 and improves its accuracy, but also significantly enhances the adaptability and stability of the detection element 410 in different operating environments. Through this integrated design, the entire detection system can form a closed-loop feedback, providing effective protection measures in the real-time monitoring of electrolytes or external liquids, ensuring the safe operation of the power supply unit 10, and reducing potential electrical faults and accident hazards.

[0129] In one embodiment, the leakage detection component 400 is connected to the cell module 300, and the leakage detection component 400 is at least partially located within the second cavity 112 and / or the first cavity 111. The advantage of this design is that it can directly and accurately detect leakage within the cell module 300 inside the second cavity 112, ensuring that potential liquid leaks can be detected and responded to promptly during the operation of the cell module 300; and / or can directly and accurately detect leakage within the capacitor module 200 inside the first cavity 111, ensuring that potential liquid leaks can be detected and responded to promptly during the operation of the capacitor module 200.

[0130] By placing the leakage detection component 400 within the second cavity 112, when electrolyte or other liquids enter the cavity, the leakage detection component 400 can quickly detect the presence of liquid and provide a feedback signal via electrical conduction, thereby achieving real-time monitoring of the battery cell module 300. This design provides reliable safety assurance for electric electrical equipment and other devices that rely on the battery cell module 300, especially under extreme operating conditions, preventing short circuits or other electrical failures caused by liquid leakage.

[0131] Similarly, when the leakage detection component 400 is installed inside the first cavity 111, it can monitor the working status and internal environment changes of the capacitor module 200 in a timely manner within the first cavity 111. Once a liquid leak occurs inside the first cavity 111, the leakage detection component 400 can quickly sense this change and transmit it to the system control unit in real time through an electrical conduction feedback signal.

[0132] This design allows the leak detection component 400 to fully cover the potential leakage area of ​​the first cavity 111, improving the accuracy of liquid leakage monitoring. By being positioned inside the cavity, the leak detection component 400 can react quickly when liquid accidentally enters the cavity, thus providing timely warning. This detection mechanism is particularly important during the operation of the capacitor module 200, especially under high load or extreme conditions, effectively preventing short circuits, electrical faults, or other potential safety hazards caused by liquid leakage.

[0133] Specifically, see Figure 1 and Figure 2 As shown, the shell structure 100 includes a placement shell 110 and an upper shell 120. The first cavity 111 and the second cavity 112 are both disposed inside the placement shell 110, and the upper shell 120 is connected to the placement shell 110 and covers the first cavity 111 and the second cavity 112.

[0134] The shell structure 100 can be manufactured by plastic injection molding or metal die casting, and the specific manufacturing process can be flexibly adjusted according to actual usage requirements. When using plastic injection molding, the lightweight and good molding properties of plastic materials give the shell structure 100 excellent cost performance and design freedom; while choosing metal die casting can provide higher strength and high temperature resistance.

[0135] The housing 110 employs a compartmentalized design, allowing for the separate placement of the battery cell module 300 and the capacitor module 200. This design enhances system safety in several ways. Specifically, in the event of electrolyte leakage or housing seal failure in a module, the compartmentalized structure of the housing 110 effectively prevents short-circuit connections within the housing, avoiding mutual interference between different modules and thus reducing the risk of malfunction. Furthermore, this design also slows down heat diffusion, preventing damage caused by localized heat concentration and extending the overall system lifespan.

[0136] The housing 110 on which the capacitor module 200 is placed adopts an independent cylindrical structure. This design not only provides a limiting and fixing function for the cylindrical capacitor 220, but also significantly enhances the overall strength of the housing 110. The independent cylindrical structure design increases the stability of the module, prevents displacement or damage under vibration or impact conditions, and ensures reliable performance in various working environments.

[0137] In addition, the design of the housing structure 100 also takes into account the ease of disassembly and assembly. When performing maintenance and repair, users can efficiently disassemble the upper housing 120, which facilitates the disassembly and maintenance of the internal battery cell module 300 and capacitor module 200.

[0138] Furthermore, the housing structure 100 also includes a sealing ring 140, which is disposed between the housing 110 and the upper housing 120 to achieve an effective sealing function. The main function of the sealing ring 140 is to prevent moisture, pollutants or other adverse substances in the external environment from entering the housing, thereby protecting the working performance of the battery module 300 and the capacitor module 200 and improving the stability and reliability of the system.

[0139] The sealing ring 140 can be manufactured from a variety of materials, including rubber, silicone, and polyurethane. Choosing the appropriate sealing material is crucial for improving sealing performance. For example, rubber sealing rings exhibit excellent wear resistance and elasticity, allowing them to adapt to movement and deformation between the housing 110 and the upper housing 120; silicone sealing rings maintain good sealing performance in both high and low temperature environments, making them suitable for extreme working conditions; and polyurethane sealing rings, with their excellent chemical resistance and weather resistance, are suitable for various industrial applications.

[0140] The sealing ring 140 not only effectively prevents liquid from entering, but also reduces pressure fluctuations inside the casing, helping to prevent structural deformation caused by changes in internal air pressure, thereby extending the service life of the casing structure 100. Furthermore, the excellent sealing performance can also improve the operating efficiency of the cell module 300 and the capacitor module 200, reducing the energy consumption of the battery system.

[0141] In one embodiment, the orthographic projection of the first cavity 111 onto the bottom surface of the housing 110 at least partially surrounds the second cavity 112. This design not only makes full use of the available space inside the housing 110, but also optimizes the overall structural layout, achieving a more compact design.

[0142] Specifically, the first cavity 111 is L-shaped, and its structural shape complements the design of the second cavity 112, forming a corresponding gap. This mutual design allows the first cavity 111 to surround the second cavity 112 while maintaining sufficient clearance for effective thermal management and electrical connections. This structural arrangement ensures a more rational layout of the battery or capacitor module, avoiding problems such as energy waste or poor heat dissipation caused by improper space utilization.

[0143] This configuration of the first cavity 111 and the second cavity 112 enhances the overall structural compactness. The spatial arrangement and layout between different modules are rationally optimized, allowing the overall device to maintain good performance while reducing its footprint. In practical applications, this compact design is highly beneficial for improving device integration, thereby integrating more functions within a limited space to meet the needs of different users.

[0144] The overall structure of the power supply unit 10 is thus made more compact. This compact design not only improves system reliability but also significantly enhances the efficiency of cooperation between modules. During operation, the compact layout helps reduce internal electrical interference and heat buildup, further improving equipment safety and service life.

[0145] Furthermore, the housing structure 100 also includes an explosion-proof valve connected to the upper housing 120 to ensure effective pressure release when the internal pressure of the housing structure 100 abnormally increases, protecting the starting power supply device 10 from damage. The explosion-proof valve not only prevents safety hazards caused by internal gas accumulation but also effectively improves the stability and reliability of the starting power supply device 10 in extreme environments. This design is particularly important for the capacitor module 200 and the battery cell module 300, as gas release and heat accumulation during charging and discharging may lead to a surge in internal pressure, potentially causing an explosion or other hazards.

[0146] Specifically, the explosion-proof valve is a waterproof and breathable valve 130, whose main function is to release gas while preventing liquid intrusion. This waterproof and breathable valve design allows the housing structure 100 to maintain internal gas flow while preventing moisture or other liquids from entering, ensuring the dryness and safety of internal components. The working principle of the waterproof and breathable valve 130 is based on a special membrane structure that opens when the internal pressure exceeds a preset value, releasing excess gas. Under normal conditions, the membrane remains closed to prevent external environmental influences. In practical implementation, the waterproof and breathable valve 130 can be manufactured using different materials, such as polytetrafluoroethylene (PTFE) or polyester. These materials not only have excellent chemical resistance but also effectively resist external pollution while ensuring breathability under certain pressure conditions.

[0147] Further, see Figure 2 and Figure 6 As shown, the power supply device 10 also includes a fixing adhesive, which is disposed inside the housing structure 100 and is connected to the capacitor module 200 and / or the battery cell module 300.

[0148] The primary function of the fixative is to precisely position and secure the capacitor module 200 and / or the cell module 300 during installation. This positioning ensures that different components maintain their optimal relative positions during assembly, thereby preventing poor contact or signal loss due to displacement or tilt. This design is crucial for ensuring the normal operation and performance of the system, especially in high-vibration or high-impact working environments, where the fixative is a key factor in ensuring component stability.

[0149] After the capacitor module 200 and the cell module 300 are successfully installed, the adhesive further enhances the connection strength between the capacitor module 200, the cell module 300, and the housing structure 100. This enhanced connection strength not only helps prevent the components from loosening or falling off during operation but also effectively reduces the risk of structural deformation due to thermal expansion or contraction. Especially under conditions of long-term operation or large temperature fluctuations, the good adhesion of the adhesive ensures a tight bond between the components, thereby maintaining the overall performance and safety of the device.

[0150] Various materials can be used to implement fixing adhesives, such as polyurethane adhesives, epoxy resin adhesives, and silicone adhesives. These materials offer good mechanical strength and temperature resistance. Specifically, polyurethane adhesives have excellent elasticity and bonding properties, making them suitable for applications requiring a certain degree of flexibility; epoxy resin adhesives possess strong bonding ability and chemical corrosion resistance, making them suitable for high-load environments; while silicone adhesives are more suitable for applications requiring resistance to aging and extreme temperatures. The selection of an appropriate fixing adhesive material can be optimized based on the actual usage environment, load requirements, and cost budget.

[0151] Specifically, the fixing adhesive includes supercapacitor fixing adhesive 510 and cell fixing adhesive 520. Supercapacitor fixing adhesive 510 is disposed in the first cavity 111 and bonded to the capacitor module 200, and cell fixing adhesive 520 is disposed in the second cavity 112 and bonded to the cell module 300.

[0152] In this structure, capacitor fixing adhesive 510 and battery cell fixing adhesive 520 are respectively provided, making the fixing of capacitor module 200 and battery cell module 300 more professional and targeted. This not only enhances the connection strength of each module, but also reduces the risk of single-point failure caused by overall bonding to a certain extent. For example, if one type of fixing adhesive ages or fails under certain conditions, the presence of another type of adhesive can continue to maintain the stability of the module and prevent the functional damage of the entire system.

[0153] It should be noted that the capacitor fixing adhesive 510 and the cell fixing adhesive 520 can be selected from different materials according to design requirements. Specifically, the supercapacitor fixing adhesive 510 can be made of polyurethane, epoxy resin, or silicone, which has good elasticity and chemical corrosion resistance, making it suitable for capacitor module connections. The cell fixing adhesive 520 can also use these materials to meet the technical requirements of the cell module. Different types of fixing adhesives have different bonding characteristics and temperature resistance; therefore, material selection should be optimized based on the working environment and load requirements of each module.

[0154] In specific implementation, the application of supercapacitor fixing adhesive 510 can enhance the stability of capacitor module 200 during charging and discharging, and prevent displacement caused by thermal expansion; while cell fixing adhesive 520 can effectively resist pressure and ensure the connection firmness of cell module 300 under high load.

[0155] Furthermore, the shell structure 100 is provided with reinforcing ribs 113, and at least some of the reinforcing ribs 113 are arranged on the outer surface of the shell structure 100.

[0156] By providing reinforcing ribs 113 on the outer surface of the housing structure 100, the overall strength of the housing structure 100 can be significantly improved, thereby enhancing its resistance to impact, pressure, and deformation. This design is particularly suitable for demanding working environments, such as industrial applications or mobile devices, and can effectively extend the system's service life and improve reliability.

[0157] The reinforcement rib 113 not only enhances the external strength of the shell structure 100 but also positively impacts the strength of the internal cavities. In some embodiments, when the reinforcement rib 113 is located within the first cavity 111 and / or the second cavity 112, it effectively improves the inner wall strength of the first cavity 111 and / or the second cavity 112, thereby enhancing the overall structural stability of the shell. This combined internal and external design effectively prevents internal damage caused by external impacts or loads, ensuring the safety and stability of the system under various operating conditions.

[0158] In specific implementation schemes, the reinforcing rib 113 can take various forms such as reinforcing plates or ribs, and the specific form can be selected according to the material of the shell and the usage environment. This design not only provides the necessary rigidity and strength enhancement, but also reduces the overall weight by optimizing material distribution, thereby improving the portability and economy of the system. It should be noted that the number and position of the reinforcing ribs can be flexibly configured according to different design requirements. For example, the number of reinforcing ribs can be 0, 1, 2 or more, and there is no unique limitation here.

[0159] In one embodiment, the outer side of the housing structure 100 is provided with a connecting portion 114, and the housing structure 100 is detachably connected to an external component through the connecting portion 114.

[0160] By providing a connecting part 114 on the outside of the housing structure 100, the connection between the housing structure 100 and external components can be facilitated. This design gives the housing structure 100 good compatibility and expandability, allowing for the quick replacement or addition of external components according to specific application requirements, thereby improving the flexibility and adaptability of the system.

[0161] The connecting part 114 can be designed with various connection methods, specifically, it can adopt various forms such as plug-in connection, threaded connection, or snap-fit ​​connection. Taking the plug-in connection as an example, the interface of the connecting part 114 can be designed as a standard plug or socket shape, facilitating quick connection with other modules. At the same time, this connection method has good repeated disassembly capability, will not cause wear on the connection parts, and further ensures the long-term stability of the connection. In this way, convenient connection between the housing structure 100 and various external components, including but not limited to sensors, controllers, or other electrical modules, can be achieved. In addition, the modular design concept can provide more flexible solutions for subsequent functional expansion or technical upgrades.

[0162] When the connector 114 is electrically connected to the capacitor module 200 and the battery cell module 300, current can be output externally through the connector 114. This design allows the current output to be not limited to the interior of the housing structure 100, but to achieve efficient power transfer to external devices through the connection interface. This feature is particularly important in applications such as electric equipment and renewable energy systems, enabling fast and stable power supply. By properly configuring the electrical characteristics of the connector 114, such as using suitable contact materials and connection methods, the contact resistance at the connection point can be effectively reduced, ensuring the efficiency and safety of the current output.

[0163] This utility model also provides an electrical device, which includes the starting power supply device 10 in any of the above embodiments.

[0164] In this electrical equipment, by providing the starting power supply device 10 in any of the above embodiments, the starting performance of the electrical equipment under various operating conditions can be effectively improved.

[0165] Specifically, the starting power supply device 10 of this embodiment provides an innovative solution to the problem of insufficient adaptability of the starting system for electrical equipment in low-temperature environments by connecting the battery module 300 and the capacitor module 200 in parallel. This design enables the starting power supply device 10 to achieve a more efficient starting effect in frigid climates, significantly improving the reliability of equipment starting. Compared with traditional lithium battery starting power supplies, under low-temperature conditions, the starting power supply device 10 of this embodiment can utilize the capacitor module 200 as an auxiliary to provide excellent high-current discharge effect. Under normal operating conditions, the battery module 300 can provide a large current independently, further improving the starting performance of the starting power supply device 10.

[0166] In terms of specific working principle, capacitor module 200 has the ability to charge and discharge rapidly, enabling it to quickly release a large current when needed to meet the instantaneous high power requirements during low-temperature startup. Unlike lithium-ion batteries, which often experience a decrease in lithium-ion migration rate at low temperatures, resulting in a significant drop in discharge capacity, capacitors have a unique charge storage mechanism that allows them to maintain high discharge efficiency even at lower temperatures, which is particularly important when starting up electrical equipment. Furthermore, the parallel connection design of cell module 300 and capacitor module 200 not only allows the capacitor to provide the necessary high-current assistance during equipment startup but also ensures the independent high-current output of cell module 300 under normal operating conditions, thereby enhancing overall startup performance.

[0167] To further enhance the safety and stability of the system, the housing structure 100 in this embodiment effectively isolates the capacitor module 200 from the battery cell module 300. This design not only helps reduce the risk of thermal runaway but also absorbs instantaneous current fluctuations under high load conditions, providing a more stable operating environment for the entire system. The capacitor can quickly respond to load changes, reducing potential risks caused by current fluctuations and ensuring the safety of the equipment during startup and operation.

[0168] In summary, the introduction of the capacitor module 200 enables the starting power supply device 10 to more effectively provide the high power required for starting under low-temperature conditions, significantly improving overall starting performance and bringing higher reliability and applicability to the electrical equipment. Furthermore, the design of this electrical equipment is particularly suitable for the electric vehicle field, providing robust starting support and meeting user needs in complex environments. By implementing the above solution, the starting capability and operational stability of the electrical equipment under various climatic conditions are fully guaranteed. In some embodiments, the design of the housing structure 100 can be widely applied to different types of electrical equipment, such as aircraft like helicopters and flying machines, and is not limited to any particular type.
