Description

Technical Field

[0001] The invention relates to the technical field of energy storage management, and specifically discloses a comprehensive energy storage management system. Background Art

[0002] With the transformation of the global energy structure and the widespread application of renewable energy, energy storage technology, as a key link connecting energy production, distribution and consumption, has become increasingly important. Energy storage systems can effectively solve the intermittent and instability problems of renewable energy, improve energy utilization efficiency, and promote the optimal configuration and utilization of energy. As the proportion of clean energy increases, the role of energy storage in the power system becomes increasingly important. For electrochemical energy storage systems, especially lithium-ion battery systems, their penetration rate is increasing rapidly due to their advantages such as high energy density, flexible application and fast response. However, the risk of thermal runaway of batteries has become increasingly prominent with their widespread application. That is, for electrochemical energy storage systems such as lithium-ion batteries, the control and management of their internal temperature is the key to ensuring the safe, stable and efficient operation of the system.

[0003] In existing energy storage systems, batteries generate a lot of heat during the charging and discharging process, which causes the battery temperature to rise. If the temperature is not properly controlled, it will not only reduce battery performance and shorten battery life, but may also cause safety accidents such as thermal runaway. Summary of the invention

[0004] The purpose of the present invention is to provide a comprehensive energy storage management system, which integrates efficient thermal management components to effectively manage the thermal performance of batteries during charging and discharging operations, thereby solving the technical problems of temperature increase that reduces battery performance and shortens battery life, and causes thermal runaway and causes safety accidents.

[0005] Specifically, the present invention is achieved through the following technical solutions:

[0006] A comprehensive energy storage management system, comprising an energy storage box and a thermal management component, wherein a plurality of battery compartments are provided on the upper part of the energy storage box, wherein energy storage batteries are inserted into the plurality of battery compartments in a one-to-one correspondence, wherein an annular gap exists between the energy storage batteries and the battery compartments, wherein a charging and discharging circuit board is provided inside the energy storage box and located below the plurality of battery compartments, wherein the bottoms of the plurality of battery compartments are connected to the charging and discharging circuit board through a joint, and a charging and discharging interface electrically connected to the charging and discharging circuit board is provided on the side of the energy storage box, wherein the charging and discharging interface and the charging and discharging circuit board are used to realize charging and discharging of the plurality of energy storage batteries;

[0007] The thermal management component includes a temperature monitoring unit and a temperature dissipation unit. The temperature monitoring unit is arranged corresponding to a plurality of battery compartments, and the temperature monitoring unit includes a first temperature sensor and a second temperature sensor. The first temperature sensor is arranged in the battery compartment and is used to monitor the temperature of the energy storage battery during charging and discharging. The second temperature sensor is arranged correspondingly near the joint between the battery compartment and the charging and discharging circuit board and is used to monitor the temperature of the joint during charging and discharging.

[0008] The temperature dissipation unit includes a medium storage cavity, a cooling plate and a spiral cooling tube. The medium storage cavity is located on the side of the energy storage box and is filled with a cooling medium. The cooling plate is correspondingly arranged in the annular gap inside multiple battery compartments, and the spiral cooling tube is correspondingly sleeved on the outside of multiple joints. The medium storage cavity is connected to the cooling plate and the spiral cooling tube through a medium circulation pipeline. The medium circulation pipeline is used to transport the cooling medium in the medium storage cavity to the cooling plate and the spiral cooling tube respectively, so as to cool down the energy storage battery and the joint when they heat up during the charging and discharging process.

[0009] Based on the above, the technical solution proposes a comprehensive energy storage management system, which includes an energy storage box and a thermal management component. The energy storage box is designed with multiple battery compartments, each of which is equipped with an energy storage battery, and the charging and discharging of the battery is controlled by a charging and discharging circuit board. At the same time, the thermal management component includes a temperature monitoring unit and a temperature dissipation unit, which accurately monitors the temperature of the battery and the connector, and uses the cooling medium to circulate and transport it to the cooling plate and the spiral cooling pipe to achieve effective cooling of the energy storage battery and the connector. Specifically, the present technical solution is different from the prior art in that, when performing temperature thermal management, the existing traditional energy storage management system usually only focuses on one point, that is, the surface temperature of the battery itself or the temperature of the charging and discharging circuit board, while ignoring the temperature of the joint between the battery and the charging and discharging circuit board. Therefore, it cannot fully reflect the actual thermal state of the battery, because the heat generated by the battery during the charging and discharging process may accumulate in local areas, resulting in uneven heat distribution, especially at the connection between the battery and the circuit board. The temperature of these areas may be significantly higher than the temperature of other parts such as the battery surface or the charging and discharging circuit board. At the same time, since the battery joint is a key component for current transmission, the increase in its temperature may cause unstable connection or even cause overheating of the joint, thereby increasing the risk of thermal runaway of the battery. Therefore, the innovation of this technical solution lies in that its temperature monitoring unit adopts a dual sensor design, which not only monitors the temperature of the battery itself, but also specially adds the monitoring of the temperature of the joint between the battery and the circuit board. The first temperature sensor is set to monitor the temperature of the energy storage battery in the battery compartment, and the second temperature sensor is specifically used to monitor the temperature of the joint between the battery compartment and the charging and discharging circuit board, thereby ensuring the comprehensiveness and accuracy of the temperature data of the energy storage system. At the same time, through the corresponding ingenious design of the temperature divergence unit, the cooling medium in the medium storage cavity is circulated and transported to the cooling plate and the spiral cooling pipe, thereby realizing direct cooling of the energy storage battery and the joint, respectively realizing direct cooling of the energy storage battery and the joint, effectively preventing battery overheating and joint overheating, and improving the overall safety and reliability of the energy storage system.

[0010] As a preferred embodiment of the above technical solution, any one of the cooling plates includes a plurality of substrates, the plurality of substrates are distributed in a circular array, and the side of each substrate close to the energy storage battery is an arc-shaped heat-conducting surface, and capillary heat-conducting tubes are arranged in an array on the heat-conducting surface, and an S-shaped flow pipe is arranged inside each of the substrates, and both ends of the flow pipe are respectively connected to the medium circulation pipe between the medium storage cavity and the cooling plate through a flexible hose.

[0011] Based on the above, this solution introduces a cooling plate with multiple substrates, and each substrate is distributed in a circular array, and the side close to the energy storage battery is an arc-shaped heat-conducting surface. This design enables the cooling plate to fit the battery shape more closely, thereby improving the heat transfer efficiency. The capillary heat pipes arranged in an array on the heat-conducting surface utilize the efficient thermal conductivity of the heat pipe technology to achieve efficient conduction and dissipation of heat on the surface of the energy storage battery. The S-shaped flow pipe inside the plate increases the flow path of the cooling medium, improves the cooling efficiency, makes the cooling more uniform, reduces the temperature difference inside the battery pack, effectively reduces the temperature rise of the battery during the charging and discharging process, and extends the service life of the battery. The medium circulation pipeline connected by the flexible hose ensures the installation and connection flexibility of the medium circulation pipeline between the cooling plate and the medium storage cavity, and ensures smooth flow of the cooling medium.

[0012] Specifically, a stand is provided between any two adjacent substrates, and the upper and lower ends of the stand are connected to the first temperature sensor through a connecting frame. A fastening member is provided in the middle of the stand and between the two first temperature sensors, and the fastening member is used to fasten the energy storage battery in the battery compartment.

[0013] Based on the above records, the technical solution further introduces a stand and a fastening member to achieve a stable fastening of the energy storage battery in the battery compartment, which ensures the stability of the energy storage battery installed in the battery compartment and increases the protection of the energy storage battery. At the same time, the upper and lower ends of the stand are connected to the first temperature sensor through a connecting frame. Such a layout can realize more comprehensive and accurate monitoring of the temperature of the energy storage battery.

[0014] Specifically, the clamping member includes a clamping head, one side of the clamping head is connected to the stand through a guide rod, and the other side thereof is in contact with the energy storage battery through an arc-shaped clamping portion, and the clamping head is provided with an outer convex skirt wrapped around the outside of the guide rod at a position relative to the back of the clamping portion, the outer convex skirt and the guide rod are slidably connected, and an accommodating cavity is formed between the clamping head and the end of the guide rod, and an air storage bag is provided in the accommodating cavity, and a thermosensitive gas is stored in the air storage bag.

[0015] The technical solution realizes uniform pressurization of the energy storage battery by contacting the energy storage battery with the arc-shaped pressing part of the pressing member, and realizes uniform pressure distribution while ensuring that the energy storage battery is pressed and squeezed, thereby avoiding damage to the energy storage battery due to excessive squeezing force. At the same time, the sliding connection between the convex skirt on the pressing member and the guide rod provides the pressing member with necessary flexibility so that it can adapt to batteries of different sizes. The air bag in the accommodating cavity utilizes the expansion characteristics of the thermosensitive gas to promote the expansion of the air bag as the energy storage battery heats up, thereby achieving the squeezing of the pressing head after the air bag expands, thereby promoting the pressing head to further squeeze and press the energy storage battery, ensuring that the energy storage battery is more stable, avoiding the energy storage battery from shaking and colliding and being damaged when the temperature rises, and ensuring the thermal stability and safety of the energy storage battery.

[0016] As a further preference, a plurality of telescopic displacement rods are further provided on the back of each substrate, any of the telescopic displacement rods comprising a sleeve, a telescopic airbag, a slider and a moving rod, one end of the sleeve is connected to the inner wall of the battery compartment, and the other end thereof is recessed inward to form a cavity, the telescopic airbag is embedded in the cavity, and the slider is slidably arranged in the cavity and connected to the telescopic airbag, the moving rod is located at one end of the sleeve, and one end thereof penetrates into the cavity inside the sleeve and is connected to the slider, the other end of the moving rod is connected to the substrate, and the telescopic airbag is penetrated by The inflation pipe in the guide rod is connected to the air bag, and a one-way valve is provided at a position of the inflation pipe close to the telescopic air bag; initially, the one-way valve is in a closed state, and when the temperature of the energy storage battery in the battery compartment gradually rises during the charging and discharging process, the thermosensitive gas in the air bag expands due to the heat, thereby causing the air pressure in the air bag to increase, so as to push the one-way valve to open, and cause the gas in the air bag to enter the telescopic air bag, so as to push the telescopic air bag to expand and contract, thereby pushing the slider to drive the moving rod to slide, so as to cause the moving rod to drive the substrate to move close to the energy storage battery.

[0017] It should be noted that the technical solution realizes that when the temperature of the energy storage battery gradually increases during the charging and discharging process, the substrate can adaptively adjust the distance between it and the energy storage battery according to the temperature change, so that it can effectively cool the energy storage battery. Specifically, when the temperature-sensitive gas in the air bag expands due to the temperature change of the energy storage battery and drives the pressing member to press against the energy storage battery for protection, the distance between the substrate and the energy storage battery is adjusted in a linked manner, so that they cooperate with each other and promote each other. When the temperature of the energy storage battery gradually increases, the temperature-sensitive gas in the air bag gradually expands, causing the air pressure inside it to gradually increase, and pushes the one-way valve to open, allowing high-pressure gas to enter the telescopic air bag, thereby pushing the slider and the moving rod, driving the substrate to move close to the energy storage battery, and increasing the distance between the substrate and the energy storage battery, thereby increasing the thermal contact between the two and promoting the energy storage battery to quickly transfer heat to the substrate, thereby improving the efficiency of thermal management, and effectively improving the efficiency of thermal management. Through this substrate adaptive adjustment mechanism, it is ensured that the energy storage battery can maintain the optimal thermal contact distance with the substrate at different temperatures, thereby effectively preventing the battery from overheating, extending the battery life, and improving the safety and reliability of the entire energy storage system.

[0018] More preferably, the temperature dissipation unit further includes a circuit board heat dissipation component for dissipating heat from the charging and discharging circuit board, the circuit board heat dissipation component including a micro-pipe, a connecting foil and a plurality of heat-conducting sheets, wherein the micro-pipe is opened inside the plate of the charging and discharging circuit board and is in a grid shape, the connecting foil is attached to the side of the energy storage box and corresponds to the charging and discharging circuit board, a plurality of heat-conducting sheet arrays are arranged on a side of the connecting foil away from the energy storage box, and an air flow channel is formed between any two adjacent heat-conducting sheets, a side of the connecting foil close to the energy storage box is connected to a heat-conducting alloy wire, and an end of the heat-conducting alloy wire away from the connecting foil extends into the micro-pipe, and is evenly distributed inside the plate of the charging and discharging circuit board through the micro-pipe.

[0019] It should be noted here that in the energy storage management system, the charging and discharging circuit board will also experience temperature changes during the charging and discharging process, and because the electronic components on the charging and discharging circuit board are relatively dense, the heat flux density of the electronic components is large when they are powered on, resulting in heat accumulation during high-power charging and discharging, which can easily cause the temperature of the charging and discharging circuit board to increase significantly, thereby affecting the normal use of the entire energy storage system and limiting its overall performance. Therefore, the technical solution further preferably designs a circuit board heat dissipation component for dissipating heat from the charging and discharging circuit board. Specifically, by opening a grid-shaped micro-pipeline in the plate of the charging and discharging circuit board, and setting a connecting foil and multiple heat-conducting plates at the lower part of one side of the energy storage box, and forming an air flow channel between adjacent heat-conducting plates, the heat dissipation area is effectively increased, and the heat exchange efficiency is improved. The heat-conducting alloy wire on the connecting foil is connected to the inside of the plate of the charging and discharging circuit board through the micro-pipeline, so as to realize the rapid conduction of the heat of the electronic components on the charging and discharging circuit board to the heat-conducting plate for timely heat dissipation, effectively preventing the circuit board from being damaged due to local overheating, and significantly improving the overall performance of the energy storage system.

[0020] Furthermore, a blocking cover for blocking the battery compartment is provided at each of the positions of the battery compartments corresponding to the upper portion of the energy storage box, and a pressure relief valve is provided on each of the blocking covers;

[0021] An exhaust duct is also installed on the upper part of one side of the energy storage box, and the exhaust duct is arranged from top to bottom. The upper end of the exhaust duct is an air inlet end, and is connected to multiple pressure relief valves through multiple air inlet branches. The lower end of the exhaust duct is an air outlet end, and is located directly above the circuit board heat dissipation component. The air outlet end of the exhaust duct is connected to a flow confluence, and the flow confluence is used to quickly discharge the gas discharged through the pressure relief mechanism and the exhaust duct through the air flow channel, so that the gas can quickly flow through the air flow channel to quickly dissipate the heat on the heat conductive plate.

[0022] This technical solution realizes an efficient pressure release mechanism by arranging a sealing cover and a pressure relief valve at the position of the battery compartment corresponding to the upper part of the energy storage box, and installing an exhaust duct on the upper part of one side of the energy storage box, thereby avoiding damage to the battery due to increased pressure in the battery compartment caused by increased temperature of the energy storage battery, and ensuring that when the battery temperature rises abnormally, the pressure in the battery compartment can be quickly released to prevent thermal runaway and potential explosion risks, thereby significantly improving the safety of the energy storage system. At the same time, through the design of the exhaust duct merger, the exhausted gas can be quickly discharged through the air flow channel. This high-speed airflow quickly dissipates the heat on the heat conductive plate, further enhancing the heat dissipation effect. It cleverly utilizes the airflow generated during the exhaust process of the pressure relief valve and converts it into a means of enhancing heat dissipation, thereby achieving efficient energy utilization and improved system safety.

[0023] More specifically, any of the pressure relief valves includes a pressure relief hole provided on a sealing cover, an internal hollow pressure relief pipe is provided in the pressure relief hole, the upper end of the pressure relief pipe passes through the pressure relief hole and is arranged relative to the sealing cover protrusion, and the lower end thereof passes through the pressure relief hole and is provided with an air inlet hole, an exhaust hole is provided around the upper end protrusion of the pressure relief pipe, and the upper end protrusion of the pressure relief pipe is connected to the pipe sleeve head of the air inlet end of the air inlet branch pipe, a pressure relief valve plate is provided inside the pressure relief pipe and at a position between the air inlet hole and the exhaust hole, the upper part of the pressure relief valve plate is connected to the pressure relief pipe by a thin spring, and initially, the pressure relief valve plate is located in the pressure relief pipe and between the air inlet hole and the air outlet hole, so as to achieve sealing between the air inlet hole and the air outlet hole.

[0024] The above-mentioned pressure relief valve structure significantly improves the safety and reliability of the energy storage system. The sealing cover and pressure relief valve arranged at the upper part of the energy storage box corresponding to the battery compartment position can respond quickly when the internal pressure of the battery increases abnormally. Through the cooperation of the pressure relief hole and the pressure relief pipe, the pressure can be released in time to prevent damage or safety accidents caused by overpressure of the battery. The pressure relief valve plate is connected to the pressure relief pipe through a fine spring, and the air inlet and exhaust holes are initially blocked. When the pressure gradually increases and the medium pressure in the pressure relief pipe is greater than the spring force, the medium pressure pushes the pressure relief valve plate up and compresses the fine spring to open the pressure relief valve plate and realize pressure release.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] 1. The present invention proposes a comprehensive energy storage management system, which includes an energy storage box and a thermal management component. The energy storage box is designed with multiple battery compartments, each of which is equipped with an energy storage battery, and the charging and discharging control of the battery is realized through the charging and discharging circuit board. At the same time, the thermal management component includes a temperature monitoring unit and a temperature dissipation unit, which accurately monitors the temperature of the battery and the connector, and uses the cooling medium to circulate and transport to the cooling plate and the spiral cooling pipe to achieve effective cooling of the energy storage battery and the connector;

[0027] 2. The present invention adopts a dual-sensor design for the temperature monitoring unit, which not only monitors the temperature of the battery itself, but also monitors the temperature of the joint between the battery and the circuit board. The first temperature sensor is set to monitor the temperature of the energy storage battery in the battery compartment, and the second temperature sensor is specifically used to monitor the temperature of the joint between the battery compartment and the charging and discharging circuit board, thereby ensuring the comprehensiveness and accuracy of the temperature data of the energy storage system. At the same time, through the corresponding ingenious design of the temperature dissipation unit, the cooling medium in the medium storage cavity is circulated and transported to the cooling plate and the spiral cooling pipe, thereby realizing direct cooling of the energy storage battery and the joint, respectively, effectively preventing overheating of the battery and overheating of the joint, and improving the overall safety and reliability of the energy storage system.

[0028] 3. The present invention realizes uniform pressurization of the energy storage battery by providing a clamping member and making the arc-shaped clamping part of the clamping member contact the energy storage battery. While ensuring the clamping and squeezing of the energy storage battery, the pressure is evenly distributed to avoid damage to the energy storage battery caused by excessive squeezing force. At the same time, the sliding connection between the outer convex skirt on the clamping member and the guide rod provides the clamping member with necessary flexibility to adapt to batteries of different sizes. The air bag in the accommodating cavity utilizes the expansion characteristics of the thermosensitive gas to promote the expansion of the air bag as the energy storage battery heats up, and then the air bag expands to squeeze the clamping head, thereby promoting the clamping head to further squeeze and press the energy storage battery, ensuring that the energy storage battery is more stable, avoiding the energy storage battery from shaking and colliding and being damaged when the temperature rises, and ensuring the thermal stability and safety of the energy storage battery.

[0029] 4. The present invention further realizes linkage and adaptive adjustment of the distance between the substrate and the energy storage battery by causing the temperature-sensitive gas in the air bag to expand when the temperature of the energy storage battery changes, thereby driving the pressing member to press against the energy storage battery for protection, so that the two can cooperate with each other and promote each other. When the temperature of the energy storage battery gradually rises, the temperature-sensitive gas in the air bag gradually expands, causing the air pressure inside to gradually increase, and pushing the one-way valve to open, allowing the high-pressure gas to enter the telescopic air bag, thereby pushing the slider and the moving rod, driving the substrate to move closer to the energy storage battery, so as to increase the distance between the substrate and the energy storage battery, thereby increasing the thermal contact between the two and promoting the energy storage battery to quickly transfer heat to the substrate, thereby improving the efficiency of thermal management, and effectively improving the efficiency of thermal management. This substrate adaptive adjustment mechanism ensures that the energy storage battery can maintain the optimal thermal contact distance with the substrate at different temperatures, thereby effectively preventing battery overheating, extending battery life, and improving the safety and reliability of the entire energy storage system;

[0030] 5. In order to further achieve effective heat management of the charging and discharging circuit board, the present invention sets a circuit board heat dissipation component to open a grid-shaped micro-pipe in the plate of the charging and discharging circuit board, and sets a connecting foil and multiple heat-conducting sheets on the lower part of one side of the energy storage box, which significantly improves the heat dissipation efficiency of the circuit board, and forms an air flow channel between the multiple heat-conducting sheets, which increases the heat dissipation area and improves the heat exchange efficiency. The heat-conducting alloy wire on the connecting foil is connected to the inside of the plate of the charging and discharging circuit board through the micro-pipe, which realizes the rapid conduction of the heat of the electronic components on the charging and discharging circuit board to the heat-conducting sheet for timely heat dissipation, effectively preventing the circuit board from being damaged due to local overheating, and significantly improving the overall performance of the energy storage system;

[0031] 6. The present invention introduces a pressure relief mechanism, arranges a blocking cover and a pressure relief valve at the position of the battery compartment corresponding to the upper part of the energy storage box, and installs an exhaust duct at the upper part of one side of the energy storage box, thereby avoiding damage to the battery due to the increase in pressure in the battery compartment caused by the increase in temperature of the energy storage battery, ensuring that when the battery temperature rises abnormally, the pressure in the battery compartment can be quickly released to prevent thermal runaway and potential explosion risks, thereby significantly improving the safety of the energy storage system. At the same time, through the design of the exhaust duct confluence, the exhausted gas can be quickly discharged through the air flow channel. This high-speed airflow quickly dissipates the heat on the heat conductive sheet, further enhancing the heat dissipation effect. It cleverly utilizes the airflow generated during the exhaust process of the pressure relief valve and converts it into a means of enhancing heat dissipation, so as to combine the pressure relief function with thermal management to form an organic whole. While ensuring the safety of the battery, it also improves the heat dissipation performance of the circuit board, achieving efficient energy utilization and improved system safety.

[0032] In summary, this technical solution provides an efficient, safe and reliable comprehensive energy storage management system by comprehensively considering multiple aspects such as temperature control, thermal management, safety protection and pressure release of the energy storage system. It aims to solve the technical challenges of thermal management and safety protection of existing energy storage systems, and to promote the further development and application of energy storage battery technology.

[0049] The temperature dissipation unit includes a medium storage chamber 50, a cooling plate 51 and a spiral cooling tube 52. The medium storage chamber 50 is located on the side of the energy storage box 1 and is filled with a cooling medium. The cooling plate 51 is correspondingly arranged in the annular gap inside the multiple battery compartments 10, and the spiral cooling tube 52 is correspondingly sleeved on the outside of the multiple joints 4. The medium storage chamber 50 is connected to the cooling plate 51 and the spiral cooling tube 52 through a medium circulation pipeline. The medium circulation pipeline is used to transport the cooling medium in the medium storage chamber 50 to the cooling plate 51 and the spiral cooling tube 52 respectively, so as to cool the energy storage battery 2 and the joint 4 when they heat up during the charging and discharging process.

[0050] The above embodiment discloses a comprehensive energy storage management system, which mainly includes an energy storage box 1 and a thermal management component. The energy storage box 1 is designed with multiple battery compartments 10, each battery compartment 10 is inserted with an energy storage battery 2, and the charging and discharging control of the battery is realized through the charging and discharging circuit board 3. At the same time, the thermal management component includes a temperature monitoring unit and a temperature dissipation unit, which accurately monitors the temperature of the battery and the connector 4, and uses the cooling medium to circulate and transport to the cooling plate 51 and the spiral cooling pipe 52 (in Figure 2 and Figure 4 As shown in the figure), effective cooling of the energy storage battery 2 and the connector 4 is achieved;

[0051] In specific implementation, the temperature monitoring unit adopts a dual sensor design, which not only monitors the temperature of the battery itself, but also specially adds the monitoring of the temperature of the battery and the circuit board connector 4. The first temperature sensor 100 is set to monitor the temperature of the energy storage battery 2 in the battery compartment 10, and the second temperature sensor 13 specifically monitors the temperature of the connector 4 between the battery compartment 10 and the charging and discharging circuit board 3, thereby ensuring the comprehensiveness and accuracy of the temperature data of the energy storage system.

In the present embodiment, it is necessary to add that, in order to facilitate the circulation of the cooling medium in the medium storage cavity 50 with the cooling plate 51 and the spiral cooling tube 52 respectively through the medium circulation pipeline, the present embodiment preferably has a circulation pump at one end of the medium circulation pipeline to facilitate continuous pumping of the cooling medium.

In the present embodiment, among many types of cooling media, mineral oil is preferably used as the specific cooling medium type. Of course, the operator can also choose other cooling media such as water, ethylene glycol or propylene glycol, as well as synthetic coolant or phase change material in actual applications. This embodiment is not specifically limited here.

[0052] Based on the above embodiments, this embodiment further discloses a preferred implementation method. Figure 3 , Figure 5 , Figure 6 and Figure 7 Any of the cooling plates 51 includes a plurality of substrates 510, which are distributed in a circular array, and a side of each substrate 510 close to the energy storage battery 2 is an arc-shaped heat-conducting surface, and an array of capillary heat-conducting tubes 513 are arranged on the heat-conducting surface. An S-shaped flow pipe 511 is arranged inside each of the substrates 510, and both ends of the flow pipe 511 are respectively connected to the medium circulation pipeline between the medium storage cavity 50 and the cooling plate 51 through a flexible hose.

[0053] It introduces a cooling plate 51 having multiple substrates 510, and each substrate 510 is distributed in a circular array, and the side close to the energy storage battery 2 is an arc-shaped heat-conducting surface. This design allows the cooling plate 51 to fit the battery shape more closely, thereby improving the heat transfer efficiency. The capillary heat pipes 513 arranged in an array on the heat-conducting surface utilize the efficient thermal conductivity of the heat pipe technology to achieve efficient conduction and dissipation of heat on the surface of the energy storage battery 2. The S-shaped flow pipe 511 inside the plate increases the flow path of the cooling medium, improves the cooling efficiency, makes the cooling more uniform, reduces the temperature difference inside the battery pack, effectively reduces the temperature rise of the battery during the charging and discharging process, and extends the service life of the battery. The medium circulation pipeline connected by the flexible hose ensures the installation and connection flexibility of the medium circulation pipeline between the cooling plate 51 and the medium storage cavity 50, and ensures smooth flow of the cooling medium.

[0054] Specifically, a stand 11 is provided between any two adjacent substrates 510, and the upper and lower ends of the stand 11 are connected to the first temperature sensor 100 through a connecting frame. A fastening member 12 is provided in the middle of the stand 11 and between the two first temperature sensors 100, and the fastening member 12 is used to fasten the energy storage battery 2 in the battery compartment 10.

[0055] This embodiment further introduces a stand 11 and a fastening member 12, such as Figure 3 and Figure 6 As shown, the energy storage battery 2 in the battery compartment 10 is firmly pressed against the energy storage battery 2, which ensures the stability of the energy storage battery 2 installed in the battery compartment 10, and increases the protection of the energy storage battery 2. At the same time, the upper and lower ends of the stand 11 are connected to the first temperature sensor 100 through the connecting frame. Such a layout can realize more comprehensive and accurate monitoring of the temperature of the energy storage battery 2. In addition, in this embodiment, for the pressing member 12, it is preferably provided with multiple, and the array is equidistantly arranged on the stand 11, so that the multiple pressing members 12 can effectively press against the energy storage battery 2 for protection;

[0056] As a further supplement to the above embodiment, the clamping member 12 includes a clamping head 120, one side of which is connected to the stand 11 through a guide rod 121, and the other side of which is in contact with the energy storage battery 2 through an arc-shaped clamping portion, and the clamping head 120 is provided with an outer convex skirt wrapped around the outside of the guide rod 121 at a position relative to the back of the clamping portion, and the outer convex skirt is slidably connected to the guide rod 121, and an accommodating cavity is formed between the clamping head 120 and the end of the guide rod 121, and an air storage bag 122 is provided in the accommodating cavity, and a thermosensitive gas is stored in the air storage bag 122.

[0057] Based on the feasible implementation methods disclosed in the above-mentioned embodiments, it realizes uniform pressurization of the energy storage battery 2, and while ensuring that the energy storage battery 2 is pressed tightly, it realizes uniform pressure distribution, thereby avoiding damage to the energy storage battery 2 due to excessive pressing force. At the same time, the sliding connection between the convex skirt on the pressing member 12 and the guide rod 121 provides the pressing member 12 with necessary flexibility so that it can adapt to batteries of different sizes. The air bag 122 in the accommodating cavity utilizes the expansion characteristics of the thermosensitive gas to promote the expansion of the air bag 122 as the energy storage battery 2 heats up, thereby realizing that the air bag 122 expands and squeezes the pressing head 120, thereby promoting the pressing head 120 to further squeeze and press the energy storage battery 2, ensuring that the energy storage battery 2 is more stable, avoiding the energy storage battery 2 from shaking and colliding and being damaged when the temperature rises, and ensuring the thermal stability and safety of the energy storage battery 2.

[0058] Based on the above embodiment, it should be noted that when the thermosensitive gas in the air bag 122 gradually expands, it means that the energy storage battery 2 is heated up rapidly at this time. At this time, heat accumulates and causes the temperature of the battery compartment 10 to rise significantly, thereby causing the air bag 122 to expand. Therefore, in order to achieve rapid heat dissipation of the energy storage battery 2 and avoid thermal runaway of the energy storage battery 2 due to excessive heating, which affects the performance of the energy storage system, it is necessary to promote effective thermal contact between the substrate 510 and the surface of the energy storage battery 2 to accelerate the heat conduction and dissipation of the energy storage battery 2. For this purpose, a preferred implementation method is proposed for the substrate 510, that is, a plurality of telescopic displacement rods 512 are provided on the back of each substrate 510 (preferably, the plurality of telescopic displacement rods 512 correspond to the plurality of fastening members 12), see for details. Figure 6Any of the telescopic displacement rods 512 includes a sleeve 5120, a telescopic airbag 5121, a slider 5122 and a moving rod 5123. One end of the sleeve 5120 is connected to the inner wall of the battery compartment 10, and the other end thereof is recessed inward to form a cavity. The telescopic airbag 5121 is embedded in the cavity, and the slider 5122 is slidably arranged in the cavity and connected to the telescopic airbag 5121. The moving rod 5123 is located at one end of the sleeve 5120, and one end thereof penetrates into the cavity inside the sleeve 5120 and is connected to the slider 5122. The other end of the moving rod 5123 is connected to the substrate 510. The telescopic airbag 5121 is inserted through the guide rod The inflation pipe in 121 is connected to the air bag 122, and a one-way valve is provided at a position of the inflation pipe near the telescopic air bag 5121; initially, the one-way valve is in a closed state. When the temperature of the energy storage battery 2 in the battery compartment 10 gradually rises during the charging and discharging process, the thermosensitive gas in the air bag 122 expands due to the heat, thereby causing the air pressure in the air bag 122 to increase, so as to push the one-way valve to open, and cause the gas in the air bag 122 to enter the telescopic air bag 5121, so as to push the telescopic air bag 5121 to expand and contract, thereby pushing the slider 5122 to drive the moving rod 5123 to slide, so as to cause the moving rod 5123 to drive the substrate 510 to move closer to the energy storage battery 2.

[0059] At the same time, the above-disclosed implementation method realizes that when the temperature of the energy storage battery 2 gradually increases during the charging and discharging process, the substrate 510 can adaptively adjust the distance between it and the energy storage battery 2 according to the temperature change, so that it can effectively cool the energy storage battery 2. Specifically, when the temperature-sensitive gas in the air bag 122 expands due to the temperature change of the energy storage battery 2 and drives the abutting member 12 to abut and protect the energy storage battery 2, the distance between the substrate 510 and the energy storage battery 2 is adjusted in a linked and adaptive manner, so that they cooperate with each other and promote each other. In specific implementation, when the temperature of the energy storage battery 2 gradually increases, the air bag 122 The temperature-sensitive gas will gradually expand and cause the gas pressure inside it to gradually increase. Since the expansion of the air bag 122 is limited and the air bag 122 pushes the fastening member 12 to be in close contact with the surface of the energy storage battery 2, the internal gas of the air bag 122 will push the one-way valve to open after the pressure is gradually increased, allowing the high-pressure gas to enter the telescopic air bag 5121, thereby pushing the slider 5122 and the moving rod 5123, driving the substrate 510 to move closer to the energy storage battery 2, and increasing the distance between the substrate 510 and the energy storage battery 2, thereby increasing the thermal contact between the two and promoting the energy storage battery 2 to quickly transfer heat to the substrate 510, thereby improving the efficiency of thermal management and effectively improving the efficiency of thermal management. It should be added here that, in this embodiment, for the one-way valve, its specific structure can be selected to be a thin plate that is compatible with the inside of the inflation pipe, and one side of the thin plate is connected to the inflation pipe through a torsion spring. Initially, the thin plate can block the inflation pipe under the action of the torsion spring, and as the thermosensitive gas in the air storage bag 122 gradually heats up and expands, its gas pressure will gradually increase, thereby squeezing the thin plate, and by twisting the torsion spring, the thin plate is turned over, thereby opening the inflation pipe, which is conducive to the transportation of the thermosensitive gas with high pressure after expansion through the inflation pipe. Of course, the specific structure of the one-way valve here is only an exemplary description (not specifically shown in the figure), and in actual application, the operator can also choose other valve structures that can block or open the inflation pipe through changes in air pressure.

[0060] Example 2

[0061] Based on the above-mentioned Example 1, a preferred implementation method different from Example 1 is proposed here. Specifically, in the energy storage management system, the charging and discharging circuit board 3 will also experience temperature changes during the charging and discharging process. Since the electronic components on the charging and discharging circuit board 3 are relatively dense, the heat flux density of the electronic components is large when they are powered on. As a result, during high-power charging and discharging, heat accumulation can easily cause the temperature of the charging and discharging circuit board 3 to increase significantly, thereby affecting the normal use of the entire energy storage system and limiting its overall performance. The prior art often ignores this point and does not perform effective thermal management on the charging and discharging circuit board 3, which is very likely to cause the performance of the circuit board to deteriorate, and even damage sensitive components, thereby affecting the stability and life of the entire energy storage system. Therefore, for this embodiment, its temperature dissipation unit also includes a circuit board heat dissipation component 53 for dissipating heat from the charging and discharging circuit board 3, see for details. Figure 8 The circuit board heat dissipation component 53 includes a micro-channel 530, a connecting foil 531 and a plurality of heat-conducting sheets 532, wherein the micro-channel 530 is opened inside the plate of the charging and discharging circuit board 3 and is in a grid shape, the connecting foil 531 is attached to the side of the energy storage box 1 and corresponds to the charging and discharging circuit board 3, and a plurality of heat-conducting sheets 532 are arranged in an array on a side of the connecting foil 531 away from the energy storage box 1, and an air flow channel is formed between any two adjacent heat-conducting sheets 532, a side of the connecting foil 531 close to the energy storage box 1 is connected to a heat-conducting alloy wire 5300, and an end of the heat-conducting alloy wire 5300 away from the connecting foil 531 extends into the micro-channel 530, and is evenly distributed inside the plate of the charging and discharging circuit board 3 through the micro-channel 530.

[0062] By further providing a circuit board heat dissipation component 53, a grid-like micro-channel 530 is opened in the plate of the charging and discharging circuit board 3, and the circuit board heat dissipation component 53 is provided at the lower part of one side of the energy storage box 1, which significantly improves the heat dissipation efficiency of the circuit board, and an air flow channel is formed between adjacent heat conducting sheets 532, thereby increasing the heat dissipation area and improving the heat exchange efficiency. The heat conducting alloy wire 5300 on the connecting foil 531 is connected to the inside of the plate of the charging and discharging circuit board 3 through the micro-channel 530, so that the heat of the electronic components on the charging and discharging circuit board 3 is quickly transferred to the heat conducting sheet 532 for timely heat dissipation, effectively preventing the circuit board from being damaged due to local overheating, and significantly improving the overall performance of the energy storage system.

[0063] Example 3

[0064] Based on the above-mentioned Embodiment 1 and Embodiment 2, a further preferred implementation mode is proposed here. Specifically, in this embodiment, a blocking cover 20 for blocking the battery compartment 10 is further provided at the position of the multiple battery compartments 10 corresponding to the upper part of the energy storage box 1, and a pressure relief valve 21 is provided on the multiple blocking covers 20. Fig. 9 ;

[0065] An exhaust duct 14 is also installed on the upper part of one side of the energy storage box 1, and the exhaust duct 14 is arranged from top to bottom. The upper end of the exhaust duct 14 is the air inlet end, and is connected to multiple pressure relief valves 21 through multiple air inlet branches 15. The lower end of the exhaust duct 14 is the air outlet end, and is located directly above the circuit board heat dissipation component 53. The air outlet end of the exhaust duct 14 is connected to a confluence 140, and the confluence 140 is used to quickly discharge the gas discharged through the pressure relief mechanism and the exhaust duct 14 through the air flow channel, so that the gas quickly flows through the air flow channel to quickly dissipate the heat on the heat conductive sheet 532. Preferably, exhaust slits 1400 are provided at the bottom of the confluence 140 corresponding to multiple air flow channel positions, such as Fig.10 As shown, when the gas is discharged through the exhaust slit 1400, the gas flow rate is faster, so that the fast-flowing gas can not only quickly carry and dissipate the heat on the heat conductive sheet 532 when blowing through the air flow channel, but also further realize the air flow blowing on the surface of the heat conductive sheet 532, thereby cleaning and blowing off the dust attached to the surface of the heat conductive sheet 532 after long-term use, to prevent dust from sticking and affecting the thermal conduction efficiency of the heat conductive sheet 532 and limiting its heat dissipation effect.

[0066] By arranging a blocking cover 20 and a pressure relief valve 21 at the position of the battery compartment 10 corresponding to the upper part of the energy storage box 1, and installing an exhaust duct 14 at the upper part of one side of the energy storage box 1, an efficient pressure release mechanism is realized, which avoids the damage of the battery caused by the pressure increase in the battery compartment 10 due to thermal runaway caused by the temperature increase of the energy storage battery 2, and ensures that when the battery temperature rises abnormally, the pressure in the battery compartment 10 can be quickly released to prevent thermal runaway and potential explosion risks, thereby significantly improving the safety of the energy storage system. At the same time, through the design of the exhaust duct 14 confluence 140, the exhausted gas can be quickly discharged through the air flow channel. This high-speed airflow quickly dissipates the heat on the heat conductive sheet 532, further enhancing the heat dissipation effect. It cleverly utilizes the airflow generated during the exhaust process of the pressure relief valve 21 and converts it into a means of enhancing heat dissipation, thereby achieving efficient energy utilization and improved system safety.

[0067] For this embodiment, more specifically, Fig. 9As shown in the figure, any of the pressure relief valves 21 includes a pressure relief hole formed on the plugging cover 20, a hollow pressure relief pipe 210 is provided in the pressure relief hole, the upper end of the pressure relief pipe 210 passes through the pressure relief hole and is convexly arranged relative to the plugging cover 20, and the lower end thereof passes through the pressure relief hole and is provided with an air inlet 212, an exhaust hole 211 is provided around the upper end protrusion of the pressure relief pipe 210, and the upper end protrusion of the pressure relief pipe 210 is connected to the inlet 212. The pipe sleeve of the air inlet end of the air branch pipe 15 is connected, and a pressure relief valve plate 213 is provided inside the pressure relief pipe 210 and located between the air inlet hole 212 and the air outlet hole 211. The upper part of the pressure relief valve plate 213 is connected to the pressure relief pipe 210 through a thin spring 214. Initially, the pressure relief valve plate 213 is located inside the pressure relief pipe 210 and between the air inlet hole 212 and the air outlet hole, so as to achieve the blockage between the air inlet hole 212 and the air outlet hole. For the pressure relief valve plate 213, it is necessary to have a sliding connection with the pressure relief pipe 210 so that the air pressure can push it to slide up and down in the pressure relief pipe 210, so as to achieve the connection or closure of the air inlet hole 212 and the air outlet hole. Therefore, in this embodiment,

[0068] Based on the structure of the pressure relief valve 21 described above, the safety and reliability of the energy storage system are significantly improved. The blocking cover 20 and the pressure relief valve 21 arranged at the upper part of the energy storage box 1 corresponding to the position of the battery compartment 10 can respond quickly when the internal pressure of the battery increases abnormally. Through the cooperation of the pressure relief hole and the pressure relief pipe 210, the pressure is released in time to prevent damage or safety accidents caused by overpressure of the battery. The pressure relief valve plate 213 is connected to the pressure relief pipe 210 through a thin spring 214, and the air inlet 212 and the exhaust hole 211 are initially blocked. When the pressure gradually increases and the medium pressure in the pressure relief pipe 210 is greater than the spring elastic force, the medium pressure pushes the pressure relief valve plate 213 upward and compresses the thin spring 214 to open the pressure relief valve plate 213 to achieve pressure release. For this embodiment, it combines the pressure relief function with thermal management to form an organic whole, which not only ensures the safety of the battery, but also improves the heat dissipation performance of the circuit board.
