Description

Technical Field

[0001] The present invention relates to a power supply system, and in particular to an integrated power storage and retrieval system for use in the power supply field. Background Technology

[0002] Integrated energy storage and power supply systems are a new type of power system that deeply integrates energy storage, power supply, and charging (or discharging) functions. They aim to achieve efficient energy utilization, grid load regulation, and renewable energy consumption. Their core components include a photovoltaic power generation system, an energy storage system, charging and discharging modules, an energy management system, and a bidirectional power regulation system. However, existing integrated energy storage and power supply systems have significant limitations in practical applications. These limitations primarily manifest in their inability to flexibly adapt to the voltage requirements of different application scenarios, thus restricting the system's application scope and making it difficult to meet the expansion needs of diverse scenarios.

[0003] To address the aforementioned issues, Chinese invention patent application CN118056701A discloses an on-board power supply system and a power supply system thereof. This system, by setting up a mains power interface, an electric rail, an AC equipment interface, and a configurable DC equipment interface, achieves controllable switching of power flow and integrated charging and discharging functions. The DC equipment interface can switch according to the operating state to charge and discharge the energy storage device, effectively adapting to different load requirements. Chinese invention patent application CN108718156A discloses a constant power DC power supply system with a wide adjustable output voltage range. By controlling the connection form of the series-parallel switching circuit, the output voltage range can be flexibly adjusted, while reducing the voltage and current stress on individual converters.

[0004] Although existing technologies have improved the voltage adaptability of integrated energy storage and power supply systems to some extent, the cumulative heat generated by energy storage devices poses a potential threat to the safe operation of the system during actual operation. Current mainstream thermal management solutions generally adopt a unified heat dissipation design, which can alleviate thermal damage to equipment. However, due to differences in the manufacturing processes of individual cells, coupled with the use of overall heat dissipation during actual charging and discharging, individual cells are prone to poor heat dissipation when experiencing abnormal temperatures, resulting in heat loss. Consequently, after long-term charge-discharge cycles, a gradual deviation in the state of charge (SOC) will occur. This unbalanced state easily triggers the typical "weakest link" effect, leading to a significant reduction in the overall energy storage life of the system, which is detrimental to the sustainable application and development of integrated energy storage and power supply systems. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to accurately control and restore the temperature of individual batteries in the energy storage device during the application of the integrated energy storage and power supply system, reduce its heat loss, and avoid the gradual deviation of its state of charge (SOC) after long-term cyclic charging and discharging, thereby improving the consistency and durability of the energy storage device.

[0006] To address the aforementioned issues, this invention provides an integrated power supply system for storage and operation, comprising a battery management subsystem mounted within a power supply control system and multiple battery packs housed within a power supply system cabinet. The battery management subsystem includes a battery management processing unit, the input of which is connected to a battery temperature acquisition unit and a phase change state sensing unit, and the output of which is connected to an independent heat dissipation control unit and an early warning feedback unit. The battery pack contains multiple individual cells. A parallel heat exchange frame is set between two adjacent individual cells. A phase change retention component that works with the individual cells is set in the parallel heat exchange frame. A phase change heat absorption pack is set in the phase change retention component. Multiple induction contacts are set in the parallel heat exchange frame, located on the upper and lower sides of the phase change heat absorption pack respectively. The input of the battery temperature acquisition unit is connected to the temperature sensor installed in the power supply system cabinet. The input of the phase change state sensing unit is connected to the sensing contact block. The output of the independent heat dissipation control unit is connected to the heat dissipation mechanism installed in the power supply system cabinet. The parallel heat exchange frame cooperates with the heat dissipation mechanism. The output of the early warning feedback unit is connected to the communication system installed in the power supply control system.

[0007] In the aforementioned integrated power supply system for energy storage and dissipation, the actual heat dissipation status of individual batteries can be sensed and monitored. When abnormal heat dissipation occurs, independent temperature control can be implemented in a timely manner, which can effectively achieve precise temperature control and recovery, reduce heat loss, and thus avoid the gradual deviation of the state of charge (SOC) of the individual battery after long-term charge-discharge cycles.

[0008] As a further improvement of this application, a heat exchange input pipe is fixedly connected to the upper rear end of the parallel heat exchange frame and communicates with it, and a heat exchange output pipe is fixedly connected to the lower front end of the parallel heat exchange frame and communicates with it. The ends of the heat exchange output pipe and the heat exchange input pipe away from the parallel heat exchange frame extend to the outside of the battery pack and communicate with the heat dissipation mechanism installed in the power supply system cabinet. Multiple parallel heat exchange frames are arranged in parallel with the heat dissipation mechanism through the heat exchange output pipe and the heat exchange input pipe.

[0009] As a further improvement of this application, the phase change holding assembly includes two shaped heat-conducting plates. The shaped heat-conducting plates are fixedly connected to both ends of the parallel heat exchange frame. A phase change heat absorption bag is fixedly connected to one end of the two shaped heat-conducting plates that is close to each other. A shaped sliding plate that slides in cooperation with the inner wall of the parallel heat exchange frame is fixedly connected to one end of the two phase change heat absorption bags that is close to each other. Multiple induction pads are fixedly connected to the shaped heat-conducting plate and the shaped sliding plate on the same side, and the multiple induction pads are symmetrically arranged on the upper and lower sides of the phase change heat absorption bag. Induction blocks are fixedly connected to the adjacent ends of the two corresponding induction pads on the left and right sides. An auxiliary elastic element that slides on the outside of the induction block is fixedly connected between the two corresponding induction pads on the left and right sides.

[0010] As a further improvement of this application, the phase change heat absorption bag is filled with a composite phase change filler made of paraffin wax, insulating thermally conductive powder and antioxidant, and the mass mixing ratio of paraffin wax and insulating thermally conductive powder is 1:0.3 to 1:0.5. The phase change heat absorption bag is made of low-density polyethylene.

[0011] As a further improvement of this application, multiple individual cells are arranged in series, and each individual cell has an independent plug-in / plug-out design.

[0012] As a further improvement of this application, a pair of thermally sensitive contact strips are fixedly connected to the upper and lower inner walls of the parallel heat exchange frame and disposed on the inner side of the two shaping slide plates. The input end of the battery management processing unit is also connected to a phase change limit sensing unit, and the input end of the phase change limit sensing unit is signal connected to the thermally sensitive contact strips.

[0013] As a further improvement of this application, an isolation sleeve fitted on the outside of the phase change heat absorption pack is fixedly connected between the heat-conducting plate and the sliding plate on the same side. A pair of shaping electromagnetic blocks are fixedly connected to the ends of the heat-conducting plate and the sliding plate on the same side, and the shaping electromagnetic blocks are arranged on the front and rear sides of the phase change heat absorption pack. The output end of the battery management processing unit is also connected to a phase change shaping auxiliary unit, and the output end of the phase change shaping auxiliary unit is signal connected to the shaping electromagnetic blocks.

[0014] As a further improvement of this application, the input terminal of the battery management processing unit is also connected to a single-cell SOC monitoring unit. The input terminal of the single-cell SOC monitoring unit is connected to the voltage and current sensor signal installed on the single cell, and the input terminal of the single-cell SOC monitoring unit is also connected to the battery temperature acquisition unit signal.

[0015] As another improvement of this application, the input terminal of the battery management processing unit is also connected to a battery power acquisition unit and a charge / discharge status acquisition unit. The input terminals of the battery power acquisition unit and the charge / discharge status acquisition unit are both connected to the battery pack signal. The output terminal of the battery management processing unit is also connected to a charge / discharge control unit, and the output terminal of the charge / discharge control unit is connected to the battery pack signal.

[0016] In summary, by combining the phase change heat absorption pack, induction pad, phase change state sensing unit, and independent heat dissipation control unit, independent heat exchange channels are formed between each individual battery cell. Combined with existing heat dissipation methods, this effectively promotes the balanced regulation of overall heat dissipation across multiple battery packs, effectively suppresses localized overheating of individual cells, reduces their heat loss, and can also sense and monitor the actual heat dissipation state of individual cells. When abnormal heat dissipation occurs, it can promptly perform independent temperature control, effectively achieving precise temperature control and recovery, reducing heat loss, and thus preventing the gradual deviation of the state of charge (SOC) of individual cells after long-term charge-discharge cycles. This effectively achieves global balanced regulation of heat loss across multiple battery packs, improves the consistency and durability of multiple battery packs, and effectively promotes the continuous application and development of integrated energy storage and power supply systems.

[0019] The three embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0020] Implementation method 1: Figure 1 and Figure 9 The diagram shows an integrated power supply system for storage and retrieval, including a power supply system cabinet 1. Multiple battery packs 2 are fixedly installed inside the rear side of the power supply system cabinet 1. A power supply control system 11, a communication system 14 located below the power supply control system 11, and an external charging management system 15 located in front of the power supply control system 11 are arranged inside the front side of the power supply system cabinet 1. The power supply control system 11, communication system 14, and external charging management system 15 work together. The front end of the power supply control system 11 extends to the outside of the power supply system cabinet 1 and is fixedly equipped with a control panel. The front end of the external charging management system 15 extends to the outside of the power supply system cabinet 1 and is fixedly equipped with an external charging panel, which is located to the left of the control panel. A converter 12 and a high-voltage box 13 located below the communication system 14 are also fixedly installed inside the front side of the power supply system cabinet 1, and the high-voltage box 13 is located behind the converter 12. The front end of the power supply system cabinet 1 is equipped with a DC charging port 111 for the battery, a photovoltaic charging port 112, a 380V charging port 113, and a protection switch 16, which are compatible with the power supply control system 11. The front end of the power supply system cabinet 1 is also equipped with a 380V output terminal 151, a 220V output socket 152, a 380V output socket 153, and a fast charging gun 154, which are compatible with the external charging management system 15. The power supply control system 11 is located on the left side of the external charging panel, along with the protection switch 16 and the 380V output terminal 154. All 1 are located below the power supply control system 11, and the protection switch 16 is located to the left of the 380V output terminal 151, the 380V output socket 153 is located below the protection switch 16, the 220V output socket 152 is located below the 380V output terminal 151, the photovoltaic charging port 112 is located below the 380V output socket 153, the 380V charging port 113 and the fast charging gun 154 are both located below the 220V output socket 152, and the fast charging gun 154 is located to the right of the 380V charging port 113.

[0021] The integrated energy storage and power supply system integrates battery management, power conversion, monitoring, and multi-output functions. It is compatible with various output voltage ranges and charging / energy storage methods, expanding the application scope of integrated energy storage and power supply systems. Suitable for various applications such as homes, industries, mobile devices, and microgrids, it features plug-and-play functionality and flexible expansion capabilities. The inclusion of a DC charging port 111, a photovoltaic charging port 112, and a 380V charging port 113 enables charging of the battery pack 2, supporting AC power, fast charging, and solar clean energy charging. The 380V output terminal 151, 220V output socket 152, 380V output socket 153, and fast charging gun 154 ensure power supply adaptability for various scenarios. It also supports both AC and DC outputs, covering various load types, and the inverter 12... The system is configured to convert battery power into AC (380V / 220V) output, or to store AC / PV power into the battery. The power supply control system 11 can monitor battery voltage, current, temperature, and charging / discharging status in real time, and provide data feedback through the control panel and communication system 14.

The external charging management system 15 can manage external charging, promoting the economic efficiency of the integrated power storage and storage system. The protection switch 16 can automatically cut off the circuit in case of abnormalities such as overload or short circuit, ensuring the safety of the equipment and battery pack 2.

[0022] The second implementation method: Figure 1 - Figure 8The integrated power supply system for storage and storage is shown, including a battery management subsystem installed in the power supply control system 11 and multiple battery packs 2 installed in the power supply system cabinet 1. The battery management subsystem includes a battery management processing unit. The input end of the battery management processing unit is connected to a battery temperature acquisition unit and a phase change state sensing unit. The output end of the battery management processing unit is connected to an independent heat dissipation control unit and an early warning feedback unit. The battery pack 2 contains multiple individual batteries 21. A parallel heat exchange frame 3 is provided between two adjacent individual batteries 21. The parallel heat exchange frame 3 is fixedly installed in the battery pack 2 by plugging in. The lower inner wall of the battery pack 2 has a slot that cooperates with the parallel heat exchange frame 3, which facilitates the subsequent replacement and maintenance of the parallel heat exchange frame 3. A phase change holding component 4 that cooperates with the individual battery 21 is provided in the parallel heat exchange frame 3. A phase change heat absorption pack 5 is provided in the phase change holding component 4. Multiple sensing contacts 61 are respectively located on the upper and lower sides of the phase change heat absorption pack 5 in the parallel heat exchange frame 3. The input of the battery temperature acquisition unit is connected to the temperature sensor located in the power supply system cabinet 1. The input of the phase change state sensing unit is connected to the sensing contact 61. The output of the independent heat dissipation control unit is connected to the heat dissipation mechanism located in the power supply system cabinet 1. The parallel heat exchange frame 3 cooperates with the heat dissipation mechanism. The output of the early warning feedback unit is connected to the communication system 14 installed in the power supply control system 11. Through the cooperation of the phase change heat absorption pack 5, the sensing pad 6, the phase change state sensing unit, and the independent heat dissipation control unit, an independent heat exchange channel is formed between each individual battery 21. Combined with the existing heat dissipation method, this effectively promotes the heat exchange of multiple batteries. The overall heat dissipation of the battery pack 2 is balanced, effectively suppressing local overheating of individual cells 21, reducing their heat loss, and sensing and monitoring the actual heat dissipation status of individual cells 21. When abnormal heat dissipation occurs, it can independently control the temperature in a timely manner, effectively achieving precise temperature control and recovery, reducing their heat loss. This avoids the gradual deviation of the state of charge (SOC) of the individual cells 21 after long-term charge-discharge cycles, thereby effectively achieving global balanced adjustment of heat loss of multiple battery packs 2, improving the consistency and durability of multiple battery packs 2, and effectively promoting the continuous application and development of integrated energy storage and power supply systems.

[0023] It should be noted that the heat dissipation mechanism is a structure used in existing energy storage devices, and is directly referenced here without any changes to its principle and structure. For example, the heat dissipation mechanism includes a liquid cooling plate, coolant, circulation system, radiator / condenser, temperature sensor, and auxiliary components. The heat generated by the charging and discharging of battery pack 2 is transferred to the liquid cooling plate through the thermal pad in the auxiliary components or through direct contact, and then conducted to the coolant. The coolant circulates under the drive of the water pump, and the heat is carried away from battery pack 2 through forced convection, forming a heat transfer path of "battery → coolant → radiator → environment". Then, when the high-temperature coolant flows through the radiator, it dissipates heat through air convection or condenser phase change such as refrigerant evaporation. After the temperature drops, it returns to battery pack 2. The independent heat dissipation control unit can dynamically adjust the water pump speed, coolant flow rate, or switch circulation modes according to the temperature sensor data to ensure the temperature uniformity of battery pack 2. Those skilled in the art can select the appropriate heat dissipation mechanism according to actual needs, which will not be elaborated further here.

[0024] Figure 1 - Figure 8The phase change heat absorber pack 5 is shown to be filled with a composite phase change filler made of paraffin wax, insulating thermally conductive powder, and antioxidant. The mass ratio of paraffin wax to insulating thermally conductive powder is 1:0.3 to 1:0.5. The insulating thermally conductive powder can be either expanded graphite or ceramic powder. Paraffin wax can absorb heat from the single cell 21 through its solid-to-liquid phase change, promoting heat dissipation of the single cell 21. The addition of insulating thermally conductive powder can improve the heat absorption efficiency of paraffin wax and the timeliness of heat exchange between the phase change heat absorber pack 5 and the single cell 21. Paraffin wax can undergo an endothermic phase change when the ambient temperature is above 40°C, thereby effectively monitoring and maintaining the heat dissipation effect of the single cell 21 and avoiding heat loss of the single cell 21. The antioxidant is added at a mass percentage of 0.5% to 2% of the mixture of paraffin wax and insulating thermally conductive powder. Diphenylamine can be selected as the antioxidant. The phase change heat absorber pack 5 is made of low-density polyethylene, which can prevent the graphite wax from absorbing heat from the insulating thermally conductive powder. The leakage of wax promotes the durability of the phase change heat absorption pack 5. Through the setting of the composite phase change filler in the phase change heat absorption pack 5, the heat absorption of the single cell 21 can be effectively achieved, so as to avoid heat accumulation and heat loss of the single cell 21. Furthermore, due to the phase change effect of heat absorption and heat release of the composite phase change filler in the phase change heat absorption pack 5, the state of the single cell 21 can be monitored, thereby ensuring the accuracy of subsequent temperature control of the single cell 21. While ensuring the heat dissipation effect, the heat dissipation cost and difficulty are reduced. During the application process, the phase change heat absorption pack 5, in conjunction with the parallel heat exchange frame 3 and the heat dissipation mechanism, can exchange the absorbed heat in a timely manner, thereby maintaining the solid phase state of its internal composite phase change filler and not frequently undergoing phase change. Phase change only occurs when the heat dissipation effect of the parallel heat exchange frame 3 and the heat dissipation mechanism on the single cell 21 is not good, or when the single cell 21 experiences abnormal temperature, thus effectively ensuring the service life of the phase change heat absorption pack 5.

[0025] Figure 3 The diagram shows that multiple individual battery cells 21 are connected in series and each individual battery cell 21 is designed for independent plug-in and plug-out. Each individual battery cell 21 can form an independent replaceable structure. When an abnormality is detected, the individual battery cell 21 can be replaced. This reduces the maintenance difficulty and cost of the battery pack 2, while effectively ensuring the energy storage effectiveness of the battery pack 2 and promoting its consistency and durability.

[0026] Figure 1 - Figure 8The parallel heat exchange frame 3 is shown to have a heat exchange input pipe 32 fixedly connected to its upper rear end and a heat exchange output pipe 31 fixedly connected to its lower front end. Both the heat exchange output pipe 31 and the heat exchange input pipe 32 extend to the outside of the battery pack 2 at their ends away from the parallel heat exchange frame 3, and are connected to a heat dissipation mechanism located in the power supply system cabinet 1. Multiple parallel heat exchange frames 3 are arranged in parallel with the heat dissipation mechanism via the heat exchange output pipe 31 and the heat exchange input pipe 32. The heat dissipation mechanism can... The parallel heat dissipation circulation pipes are connected to the parallel heat exchange frame 3 via heat exchange output pipe 31 and heat exchange input pipe 32. The flow rate of the coolant is controlled by the regulating valves set on the heat dissipation circulation pipes, thereby forming an independent heat exchange function and heat exchange regulation for each parallel heat exchange frame 3. This can avoid heat loss caused by local overheating of individual cells 21, ensure the overall heat loss balance of the battery pack 2, avoid the gradual deviation of the state of charge (SOC), and improve the consistency and durability of the battery pack 2.

[0027] Figure 1 - Figure 8 The phase change retaining assembly 4 includes two shaped heat-conducting plates 41. The shaped heat-conducting plates 41 are fixedly connected to both ends of the parallel heat exchange frame 3. The phase change heat absorption packs 5 are fixedly connected to one end of the two shaped heat-conducting plates 41. The shaped slide plates 42 that slide in a sliding fit with the inner wall of the parallel heat exchange frame 3 are fixedly connected to one end of the two phase change heat absorption packs 5. Multiple induction pads 6 are fixedly connected to the near ends of the shaping heat-conducting plate 41 and shaping slide plate 42 on the same side. These induction pads 6 are symmetrically arranged on the upper and lower sides of the phase change heat-absorbing package 5. Induction contacts 61 are fixedly connected to the near ends of two corresponding left and right induction pads 6. An auxiliary elastic element 62, slidingly fitted onto the outside of the induction contacts 61, is fixedly connected between the two corresponding left and right induction pads 6. As the phase change heat-absorbing package 5 gradually transforms from a solid phase to a liquid phase, gravity causes the packing material inside the phase change heat-absorbing package 5 to move downwards, resulting in expansion and deformation of the phase change heat-absorbing package 5. This pushes the shaping slide plate 42 to move. The thermal sensing strip 33 can sense the movement position of the shaping slide plate 42. Once the device moves to contact the phase change heat absorber 5, it indicates that the phase change heat absorber 5 has expanded and deformed to its upper limit. The temperature of the individual cell 21 and its heat dissipation effect on the individual cell 21 are abnormal. The device can sense and trigger feedback on the actual heat dissipation state of the individual cell 21, which facilitates timely regulation of the heat dissipation effect, improves response efficiency, and avoids the danger caused by continuous overheating. Furthermore, the setting of the sensing contact 61 and the phase change state sensing unit can sense and trigger the phase change heat absorber 5 when it undergoes initial deformation. This not only improves the accuracy of independent temperature control of the individual cell 21, but also effectively avoids performance damage caused by the continuous expansion of the phase change heat absorber 5, promotes the durability of the phase change heat absorber 5, avoids paraffin leakage, and ensures the safety and effectiveness of the continuous application of the battery pack 2.

[0028] Figure 2 The input terminal of the battery management processing unit is also connected to a single-cell SOC monitoring unit. The input terminal of the single-cell SOC monitoring unit is connected to the voltage and current sensor signal installed on the single cell 21, and the input terminal of the single-cell SOC monitoring unit is also connected to the battery temperature acquisition unit signal. The single-cell SOC monitoring unit can monitor the state of charge (SOC) of the single cells 21 in the battery pack 2. When the state of charge (SOC) deviates, the single cell 21 that deviates can be replaced and maintained in time to ensure the overall energy storage life of multiple battery packs 2. This reduces the maintenance difficulty of the integrated energy storage and power supply system and promotes the continuous effectiveness of its energy storage function.

[0029] Figure 2The input terminal of the battery management processing unit is connected to a battery power acquisition unit and a charge / discharge status acquisition unit. The input terminals of both the battery power acquisition unit and the charge / discharge status acquisition unit are connected to the battery pack 2. The output terminal of the battery management processing unit is connected to a charge / discharge control unit. The output terminal of the charge / discharge control unit is connected to the battery pack 2. This allows for real-time sensing and control of the operating status and power data of the battery pack 2, preventing overcharging or over-discharging, and promoting the optimization of the charge / discharge of the battery pack 2 by the battery management processing unit, thereby improving the safety and service life of the battery pack 2.

[0030] Figure 1 - Figure 8 This demonstrates that, in the application of an integrated power supply system for energy storage and storage, to reduce the overall manufacturing cost of the integrated power supply system, the placement of the conventional battery pack 2 and the improved battery pack 2 can be planned according to the setting position of the battery pack 2 in the power supply system cabinet 1. The conventional battery pack 2 is placed on the outside, and the improved battery pack 2 is placed on the inside. In this way, while reducing costs, the conventional battery pack 2 located on the outside can also be effectively cooled through the application of a heat dissipation mechanism. Through the combination of the heat dissipation mechanism with the parallel heat exchange frame 3 and the phase change heat absorption pack 5, the improved battery pack 2 is assisted in heat dissipation and monitoring, avoiding heat loss and safety issues of individual batteries 21 caused by the overall heat dissipation not being able to effectively act on the inside position.

[0031] The battery management processing unit, through the battery power acquisition unit, can detect the stored energy data in the battery pack 2. Combined with data transmitted by the charge / discharge status acquisition unit regarding whether the battery pack 2 is currently charging, discharging, or in standby mode, the charging / discharge control unit can automatically stop the charging or discharging process when the battery pack 2 is low on power or fully charged. This prevents performance damage caused by overcharging or over-discharging. Furthermore, when the battery pack 2 is in standby mode for an extended period and is low on power, the battery management processing unit can control the communication system 14 to output warning data via the early warning feedback unit, reminding the user to charge promptly and preventing damage to the battery pack 2 caused by prolonged low power. During the charging and discharging process of the battery pack 2, a temperature sensor installed in the power supply system cabinet 1 can monitor the temperature within the power supply system cabinet 1. The overall operating temperature of each battery pack 2 is collected and transmitted to the battery management processing unit via the battery temperature acquisition unit. The battery management processing unit controls the heat dissipation mechanism through an independent heat dissipation control unit based on the temperature data. This ensures that the heat dissipation mechanism provides heat dissipation protection for the battery pack 2, preventing the overall temperature of the battery pack 2 from becoming too high and causing thermal damage. This ensures the safety and effectiveness of the charging and discharging process of the battery pack 2. Furthermore, the battery management processing unit controls the heat dissipation mechanism through the independent heat dissipation control unit, enabling it to exchange heat with the parallel heat exchange frame 3 through parallel heat dissipation circulation pipes, heat exchange output pipes 31, and heat exchange input pipes 32. This promotes heat dissipation of the individual batteries 21, ensuring the effectiveness of heat dissipation during the application of the individual batteries 21, reducing their heat loss, and promoting the uniformity of heat dissipation for the multiple battery packs 2 as a whole.

[0032] Furthermore, during the charging and discharging process of battery pack 2, the phase change heat absorption pack 5 can absorb the heat generated by the individual battery 21 through the temperature conduction of the shaped heat-conducting plate 41. And because the parallel heat exchange frame 3 generates continuous heat exchange under the heat dissipation mechanism, it can exchange heat within the phase change heat absorption pack 5 through the shaped sliding plate 42, ensuring the effectiveness of the phase change heat absorption pack 5 in continuously absorbing heat from the individual battery 21. When the heat absorbed by the phase change heat absorption pack 5 from the individual battery 21 is greater than the heat exchanged by the parallel heat exchange frame 3, the phase change heat absorption pack 5 absorbs heat from the individual battery 21. The composite phase change filler inside the phase change heat exchanger 5 undergoes a phase change, which, under the influence of gravity, causes the composite phase change filler to accumulate downwards within the phase change heat exchanger 5. This causes the phase change heat exchanger 5 to expand and deform. This expansion and deformation causes the shaping slide plate 42 to move within the parallel heat exchange frame 3, increasing the distance between the shaping heat conduction plate 41 and the shaping slide plate 42 located on the same side. This exerts a certain tensile force on the isolation sleeve 43 and the auxiliary elastic element 62, thereby... When the two abutting inductive contacts 61 separate, the phase change state sensing unit transmits disconnection trigger data to the battery management processing unit. The battery management processing unit determines that the heat dissipation of the single cell 21 is abnormal, and then controls the heat dissipation mechanism through the independent heat dissipation control unit. The heat dissipation mechanism enhances the heat exchange of the parallel heat exchange frame 3 at this location, promotes heat exchange of the phase change heat absorption pack 5, and ensures that the composite phase change material in the phase change heat absorption pack 5 continuously and effectively assists the heat dissipation of the single cell 21, so as to ensure the safety of the single cell 21 application, reduce the heat loss of the single cell 21, and effectively achieve precise temperature control of the single cell 21, avoiding the gradual deviation of the state of charge (SOC). In this way, in the application of the integrated power supply system for energy storage and storage, precise temperature control of the battery pack 2 is achieved, so as to achieve global balanced adjustment of the heat loss of multiple battery packs 2, improve the consistency and durability of multiple battery packs 2, and effectively promote the continuous application and development of the integrated power supply system for energy storage and storage.

[0033] The single-cell SOC monitoring unit can monitor the voltage and current data of the single cell 21 during charging and discharging, and then combine the monitoring data with the temperature data transmitted by the battery temperature acquisition unit to compensate for the monitoring data, thereby determining the state of charge (SOC) of each single cell 21, and synchronously transmitting the data to the battery management processing unit. When the battery management processing unit determines that a single cell 21 has a deviation in state of charge (SOC), it transmits the deviation data through the early warning feedback unit and the communication system 14, so as to promote maintenance personnel to replace and maintain the single cell 21 in a timely manner, thereby ensuring the overall performance of multiple single cells 21. While reducing maintenance difficulty and cost, it effectively promotes the economy and safety of the continuous application of the integrated energy storage and power supply system.

[0034] The third implementation method: Figure 1 - Figure 8 The integrated power supply system for storage and operation is shown. The upper and lower inner walls of the parallel heat exchange frame 3 are fixedly connected with a pair of thermal induction contact strips 33, which are set inside the two shaping slide plates 42. The input end of the battery management processing unit is also connected to a phase change limit sensing unit. The input end of the phase change limit sensing unit is connected to the thermal induction contact strips 33. The cooperation between the phase change limit sensing unit and the thermal induction contact strips 33 can realize the sensing and triggering feedback of the limit position of the phase change state of the phase change heat absorption pack 5, effectively realizing the verification and early warning of the temperature control effect. In addition, the thermal induction contact strips 33 can also display the expansion deformation of the phase change heat absorption pack 5, avoiding deformation damage caused by the continuous expansion of the phase change heat absorption pack 5, and ensuring its sealing performance of the composite phase change filler.

[0035] Figure 1 - Figure 8 A heat-conducting plate 41 and a heat-conducting slide plate 42 located on the same side are fixedly connected by an isolation sleeve 43 fitted on the outside of the phase change heat-absorbing pack 5. A pair of heat-conducting plates 41 and 42 located on the same side are fixedly connected to each other at their closest ends. The heat-conducting plates 41 and 42 are positioned on the front and rear sides of the phase change heat-absorbing pack 5. The output of the battery management processing unit is also connected to a phase change heat-conducting auxiliary unit. The output of the phase change heat-conducting auxiliary unit is signal-connected to the heat-conducting plates 44. The heat-conducting plates 41 and 42 are positioned on the front and rear sides of the phase change heat-absorbing pack 5. The variable shaping auxiliary unit can perform a reverse recovery function on the phase change heat absorption pack 5 after the phase change heat absorption pack 5 undergoes an endothermic phase change, in cooperation with the independent heat dissipation control unit. It can also move the shaping slide plate 42, increase the mobility of the composite phase change filler in the phase change heat absorption pack 5, and promote the uniformity of the distribution of the composite phase change filler in the phase change heat absorption pack 5 when it undergoes a reverse recovery. This ensures the heat absorption effect of the phase change heat absorption pack 5 on the single cell 21 and promotes its continuous application effectiveness.

[0036] Figure 1 - Figure 8 This demonstrates that when a single cell 21 experiences heat dissipation anomaly, the battery management processing unit controls the heat dissipation mechanism through an independent heat dissipation control unit. This enhances the heat exchange effect of the parallel heat exchange frame 3 at that location. Simultaneously, the battery management processing unit also controls the shaping electromagnetic block 44 through a phase change shaping auxiliary unit. This causes the two shaping electromagnetic blocks 44, located on the same side and respectively set on the shaping heat conduction plate 41 and the shaping slide plate 42, to magnetically attract each other. This controls the shaping slide plate 42 to move closer to the shaping heat conduction plate 41. The shaping slide plate 42 then squeezes the phase change heat absorption pack 5, squeezing and filling the composite phase change filler, which has changed to a liquid phase, onto the upper side of the phase change heat absorption pack 5, maintaining the uniformity and effectiveness of its subsequent heat absorption of the single cell 21. When the composite phase change filler in the phase change heat absorber 5 no longer generates a phase change effect, the electromagnetic attraction force of the shaping electromagnetic block 44 is greater than the expansion deformation force of the liquid phase composite phase change filler on the phase change heat absorber 5. The shaping slide plate 42 can drive the phase change heat absorber 5 to generate a complete or incomplete reset. The increased heat exchange effect of the parallel heat exchange frame 3 will absorb heat from the liquid phase composite phase change filler, promote its reverse phase change, and gradually change to a solid phase. As a result, the shaping slide plate 42 will not trigger the corresponding thermal sensing strip 33. The battery management processing unit determines that the independent control effect is effective at this time based on the non-contact signal transmitted by the phase change limit sensing unit. When the composite phase change filler in the phase change heat absorber 5 continues to generate phase change, the composite phase change filler, which is constantly changing into liquid phase, gradually moves downward under the action of gravity, generating an expansion deformation force on the phase change heat absorber 5. After the expansion deformation force is greater than the electromagnetic attraction force of the shaping electromagnetic block 44, the expansion deformation of the phase change heat absorber 5 will continue to drive the shaping slide plate 42 to move until the shaping slide plate 42 moves to abut against the heat-sensing contact strip 33 and is blocked. At the same time, the battery management processing unit can receive the contact signal transmitted by the phase change limit sensing unit and determine that the independent control effect is ineffective or poor. Then, while simultaneously acting on the independent heat dissipation control unit to further promote the heat dissipation effect, it also controls the operation of the battery pack 2 to stop through the charge and discharge control unit to avoid safety hazards caused by continuous overheating. The warning feedback signal is transmitted through the warning feedback unit and the communication system 14 so that maintenance personnel can check and maintain the battery pack 2 in a timely manner, judge the cause of the abnormality, and avoid abnormalities in subsequent continuous use.

[0037] After the battery management processing unit controls the operation of the battery pack 2 to stop via the charge / discharge control unit, the battery management processing unit can continuously control the independent heat dissipation control unit and assist in the control of the phase change shaping auxiliary unit. While continuously exchanging heat with the parallel heat exchange frame 3 to prevent the phase change heat absorption pack 5 from releasing heat and causing heat loss to the individual battery 21, the phase change shaping auxiliary unit can also control the shaping electromagnetic block 44 to generate alternating electromagnetic attraction and repulsion, with the magnitude of the electromagnetic attraction current being greater than that of the electromagnetic repulsion current. Thus, under the alternating electromagnetic action, phase change protection is achieved. The component 4 drives the movement of the phase change heat absorber 5, promoting the movement of the composite phase change filler inside the phase change heat absorber 5. This promotes the uniformity of the mixing of paraffin and insulating thermally conductive powder inside the pack. At the same time, it can continuously reset and regulate the shaping slide plate 42, extruding the phase change heat absorber 5 and causing the composite phase change filler to gradually and evenly distribute throughout the phase change heat absorber 5. Combined with the continuous heat exchange effect of the parallel heat exchange frame 3, the composite phase change filler inside the phase change heat absorber 5 undergoes effective reverse deformation, gradually changing from liquid phase to solid phase. This ensures its subsequent heat absorption effect on the single cell 21 and promotes the effectiveness of the continuous application of the phase change heat absorber 5.

[0038] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
