Description

Technical Field

[0001] The present invention relates to the field of new energy storage technology, and in particular to a distributed new energy storage power station and a scheduling method. Background Art

[0002] As the global energy structure transition accelerates, energy storage power stations have become core infrastructure in scenarios such as grid frequency regulation and new energy consumption. Lithium-ion batteries, due to their high energy density and long cycle life, account for over 80% of the electrochemical energy storage market. However, temperature sensitivity has become a key bottleneck restricting their large-scale application. High temperatures can cause annual battery degradation rates as high as 12-18%, far exceeding the theoretical design lifespan. Low temperatures can cause a sudden drop in capacity, severely limiting their application in high-latitude regions. Furthermore, localized overheating can cause a loss of over 15% of the battery pack's available capacity and trigger a chain reaction of thermal runaway.

[0003] Existing new energy storage systems maintain a constant temperature for batteries through cooling or heating. To save space and improve battery storage efficiency, batteries are typically stacked directly. Even with external cooling or heating, some batteries are less affected by the equipment. Furthermore, external equipment maintains continuous operation during the cooling or heating process, which increases energy consumption.

[0004] In addition, new energy storage batteries will mainly generate heat during operation, which can easily lead to overheating. The current behavior of dissipating heat is generally to use air circulation. When air flows over a large range, dust from the external environment will inevitably enter the new energy storage equipment. Dust can easily make heat dissipation more difficult. At the same time, conductive dust will affect the short circuit of the equipment, which will greatly affect the new energy storage equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide a distributed new energy storage power station and a scheduling method to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a distributed new energy storage power station, comprising an energy storage box and a frame inside the energy storage box, wherein the frame has multiple groups of support frames for supporting energy storage batteries, the support frames being slidable in the vertical direction along the frame, and a spacing adjustment portion being supported between the upper and lower groups of the support frames, the spacing adjustment portion comprising:

[0007] Sleeve 1, installed at the corners of a set of support frames;

[0008] Sleeve 2 is installed at another set of adjacent support frame corners. Sleeve 1 and Sleeve 2 are connected together, and there is sealed gas inside the two. When the temperature inside the energy storage box changes, the volume of the sealed gas changes, thereby changing the degree of connection between Sleeve 1 and Sleeve 2 and changing the spacing between the energy storage batteries.

[0009] A temperature detector is installed on the outside of the sleeve to monitor temperature changes in real time;

[0010] The sleeve has a sealing portion at one end thereof for achieving sealing between the sleeves 1 and 2;

[0011] The sealing part includes a layer body integrally formed on the sleeve end of sleeve 1, the outer ring surface of the layer body is in contact with the inner wall of sleeve 2, the outer ring of the layer body is provided with groove 1, and the groove 1 is provided with a sealing ring, and the sealing ring is squeezed with the inner wall of sleeve 2 to form a seal.

[0012] Furthermore, the four corners of the two adjacent groups of support frames all have spacing adjustment parts, and the outer sides of the sleeves of the four groups of spacing adjustment parts are all integrally provided with connecting ends, and the connecting ends are connected to the conductive tubes. Several conductive tubes form a frame-type connected with the four groups of spacing adjustment parts, and the air pressure in the four groups of spacing adjustment parts remains the same.

[0013] Furthermore, the conductive tube 1 on one side of a different layer is connected to a longitudinally extending conductive tube 2, and the conductive tube 2 is used to connect the spacing adjustment parts of different layers. The energy storage box is provided with a controller and an air pump outside, and the conductive tube 2 is connected to the air pump. The inner end of the sleeve 1 also has an air pressure detector for detecting air pressure changes. The air pressure detector and the air pump are both electrically connected to the controller, and the air pump is used to inflate the interior of the spacing adjustment part.

[0014] Furthermore, the sealing ring is made of polyurethane or hydrogenated nitrile rubber.

[0015] Furthermore, the outer ring of the layer body is also provided with at least two grooves 2, and the two grooves 2 are located on both sides of groove 1 respectively. A cylindrical inner cavity is provided inside the layer body, and a connecting groove connected to the two grooves 2 is provided on the inner wall of the inner cavity facing outward. A spring is provided in the inner cavity, and a baffle is fixed to the outward end of the spring, and the baffle is in contact with the inner wall of the inner cavity. The spring and the baffle are used to push the lubricating oil in the inner cavity to fill it into groove 2.

[0016] Furthermore, an outer end cover is fixed to the outer side of the layer body by bolts, and the outer end cover is used to cover the inner cavity.

[0017] Furthermore, a filling hole is opened inside the layer body, one end of the filling hole is connected to the second groove, and the other end passes through the outer end cover outward, and a one-way valve for closing the filling hole is embedded inside the filling hole.

[0018] Furthermore, both ends of the second sleeve are through-set, and the end away from the first sleeve is fixed to the outer cover by bolts, the outer cover and the second sleeve are sealed, and the outer cover is fixed to the corners of the support frame.

[0019] A method for dispatching a distributed new energy storage power station comprises the following steps:

[0020] Step 1: Real-time collection of the temperature of the temperature detector inside the energy storage box and the state of charge of the battery pack;

[0021] Step 2: Obtain grid load demand and time-of-use electricity price signals, and set a preset temperature threshold range for the energy storage box;

[0022] Step 3: Dynamically adjust the charge and discharge power threshold of the energy storage box according to the temperature data of the temperature detector, and reduce the charge and discharge rate when the temperature exceeds the safety threshold.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] 1. The spacing adjustment part composed of sleeve 1 and sleeve 2 uses the principle of thermal expansion and contraction of gas to achieve dynamic adjustment of the battery layer spacing. In a high temperature environment, the gas expands, increasing the air circulation cross-sectional area and reducing external cooling energy consumption. In a low temperature environment, the gas contracts to reduce the layer spacing and reduce the air circulation cross-sectional area.

[0025] 2. By setting up a structure for continuously releasing lubricating oil into groove 2, the friction coefficient of the sealing ring is reduced during movement, avoiding seal failure caused by dry friction. In addition, sustainable lubrication can be achieved by externally injecting lubricating oil.

[0026] 3. Through the conductive tube 1 and the conductive tube 2, the air pressure of each spacing adjustment part is made the same, avoiding the force that tends to bend, so that the sleeve 1 and the sleeve 2 only have the force to move up and down. In addition, the air pressure inside the spacing adjustment part is detected by the air pressure detector to achieve the purpose of reminder. At the same time, when there is a leak, the operation of the air pump can be controlled by the controller. When the air intake is greater than the air output, the support function is maintained to prevent the energy storage battery from stacking due to damage to the spacing adjustment part.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0039] See also Figures 1-9The present invention provides a technical solution: the power generated by energy storage batteries varies under environmental changes. When the ambient temperature is high, the energy storage batteries generate heat and transfer the heat to the environment. However, due to the limited difference in ambient temperature, the heat dissipation efficiency is limited. Increasing the gap between stacked energy storage batteries can increase the circulation of gas, thereby dissipating the heat of the energy storage batteries to the environment and stabilizing the temperature of the energy storage batteries to a certain extent. When the ambient temperature is low, it will also affect the working efficiency of the energy storage batteries. The heat dissipation efficiency of stacked energy storage batteries is relatively high when the temperature difference is large. Therefore, the gap between the energy storage batteries is reduced to reduce the efficiency of gas circulation, so that the temperature of the energy storage batteries can be preserved to a certain extent. Based on this, a distributed new energy energy storage power station is proposed, including an energy storage box 1 and a frame 3 inside the energy storage box 1. The frame 3 has multiple groups of support frames 4 for supporting energy storage batteries. The support frames 4 can slide up and down along the frame 3. A spacing adjustment part 5 is supported between the upper and lower groups of support frames 4. The spacing adjustment part 5 includes:

[0040] Sleeve 1 51, installed at the corner of a set of support frames 4;

[0041] Sleeve 2 54 is installed at the corner of another set of adjacent support frames 4. Sleeve 1 51 and sleeve 2 54 are connected together. There is sealed gas inside the two. When the temperature inside the energy storage box 1 changes, the volume of the sealed gas changes, realizing the change of the degree of connection between sleeve 1 51 and sleeve 2 54, and changing the spacing between the energy storage batteries.

[0042] The temperature detector 8 is installed on the outside of the sleeve 51 and is used to monitor the temperature changes in real time.

[0043] Specifically, the frame 3 is fixed inside the energy storage box 1 and extends longitudinally. Multiple groups of support frames 4 are slidably installed on the frame 3. The support frames 4 are limited to the frame 3 by a clamping method, and the support frames 4 can move longitudinally along the frame 3. A spacing adjustment part 5 is installed between the upper and lower adjacent support frames 4, which is used to automatically adjust the spacing between the support frames 4 and the support frames 4, so as to realize the change of the spacing between adjacent energy storage batteries, thereby changing the degree of air circulation.

[0044] It should be noted that the spacing adjustment part 5 includes sleeve 1 51 and sleeve 2 54. Sleeve 1 51 and sleeve 2 54 are connected and supported on the corners of two adjacent groups of support frames 4. The gas inside sleeve 1 51 and sleeve 2 54 is in a sealed state, and the change in external ambient temperature will produce a change in volume, thereby realizing the change of the spacing between the two adjacent groups of support frames 4.

[0045] The four corners of the two adjacent groups of support frames 4 are each provided with a spacing adjustment portion 5. The outer sides of the sleeves 51 of the four groups of spacing adjustment portions 5 are all integrally provided with a connecting end 52, and the connecting end 52 is connected to a conductive tube 6. Several conductive tubes 6 form a frame-type connected with the four groups of spacing adjustment portions 5, and the air pressure in the four groups of spacing adjustment portions 5 remains the same.

[0046] Specifically, the gas content within the spacing adjustment sections 5 at the four corners of two adjacent groups of support frames 4 is the same. Furthermore, because sleeves 1 51 and 2 54 can only extend longitudinally, the support frames 4 can only slide on the frame 3, and the spacing adjustment sections 5 at the same level are connected by conductive tube 1 6, the support frames 4 remain level. It should be noted that due to the interconnection of sleeves 1 51 and 2 54 and the presence of gas within them, changes in ambient temperature and the temperature of the energy storage battery are slow. Therefore, the gas within sleeves 1 51 and 2 54 is also slowly affected, eliminating the possibility of damaging the energy storage battery.

[0047] The conductive tube 1 6 on one side of different layers is connected to a longitudinally extending conductive tube 2 7, which is used to connect the spacing adjustment parts 5 of different layers. The energy storage box 1 is provided with a controller and an air pump 2 outside, and the conductive tube 2 7 is connected to the air pump 2. The inner end of the sleeve 1 51 is also provided with an air pressure detector for detecting air pressure changes. The air pressure detector and the air pump 2 are both electrically connected to the controller. The air pump 2 is used to inflate the interior of the spacing adjustment part 5.

[0048] Specifically, the spacing adjustment parts 5 of different layers are connected through the conductive tube 2 7, and are connected to the conductive tube 2 7 through the air pump 2. The air pressure change inside the spacing adjustment part 5 is detected by the air pressure detector, and the signal is transmitted to the controller. The controller controls whether the air pump 2 supplies air. It should be noted that when the air pressure becomes 0, the air pump 2 supplies air, and there is air intake and exhaust at the same time. When the air intake is greater than the air output, it maintains a supporting function to prevent the energy storage batteries from stacking due to damage to the spacing adjustment part 5.

[0049] One end of the sleeve 1 51 is provided with a sealing portion 53 for achieving a seal between the sleeve 1 51 and the sleeve 2 54;

[0050] The sealing portion 53 includes a layer body 531 integrally formed on the sleeve end of the sleeve 1 51. The outer ring surface of the layer body 531 is in contact with the inner wall of the sleeve 2 54. The outer ring of the layer body 531 is provided with a groove 1 532. The groove 1 532 has a circle of sealing ring 533. The sealing ring 533 is squeezed with the inner wall of the sleeve 2 54 to form a seal.

[0051] Specifically, the first sleeve 51 and the second sleeve 54 are sealed by a sealing ring 533 to limit the internal gas.

[0052] The sealing ring 533 is made of polyurethane or hydrogenated nitrile rubber, and the use of polyurethane or hydrogenated nitrile rubber makes the sealing ring 533 more wear-resistant.

[0053] The outer ring of the layer body 531 is also provided with at least two grooves 538, and the two grooves 538 are located on both sides of the groove 1 532. A cylindrical inner cavity 534 is provided inside the layer body 531, and a connecting groove 537 connected to the two grooves 538 is provided on the inner wall of the inner cavity 534 at the outward end. A spring 535 is provided in the inner cavity 534, and a baffle 536 is fixed to the outward end of the spring 535. The baffle 536 is in contact with the inner wall of the inner cavity 534. The spring 535 and the baffle 536 are used to push the lubricating oil in the inner cavity 534 to fill it into the groove 2 538.

[0054] Specifically, by providing a second groove 538 filled with lubricating oil on the outer side of the layer 531 , the route along which the sealing ring 533 passes is kept filled with lubricating oil when the sealing ring 533 moves along with the layer 531 , thereby preventing the sealing ring 533 from being too dry and affecting its quality.

[0055] An outer end cap 539 is also bolted to the outside of the layer 531. This outer end cap 539 covers the inner cavity 534. It should be noted that the removable outer end cap 539 allows the inner cavity 534 to be opened and closed, allowing the spring 535 and the retaining plate 536 to be installed and removed. It should also be noted that when the outer end cap 539 is fixed to the layer 531, it is sealed to prevent the lubricating oil in the inner cavity 534 from flowing outward.

[0056] A filling hole 530 is provided inside the layer body 531. One end of the filling hole 530 is connected to the groove 2 538, and the other end passes through the outer end cover 539 outward. A one-way valve is embedded inside the filling hole 530 for closing the filling hole 530. The one-way valve allows lubricating oil to be injected into the filling hole 530, but the lubricating oil cannot overflow outward.

[0057] The second sleeve 54 is provided with through-holes at both ends. The end away from the first sleeve 51 is fixed to the outer cover 55 by bolts. The outer cover 55 and the second sleeve 54 are sealed together, and the outer cover 55 is fixed to the corners of the support frame 4. It should be noted that when injecting lubricating oil into the filling hole 530, it is necessary to keep the outer side of the second groove 538 in contact with the inner wall of the second sleeve 54. Therefore, it is necessary to set the two ends of the second sleeve 54 through-holes and removably fix the outer cover 55 to the second sleeve 54 to ensure that the outer side of the second groove 538 is in contact with the inner wall of the second sleeve 54 and lubricating oil is injected from the filling hole 530. Example

[0058] A method for dispatching a distributed new energy storage power station comprises the following steps:

[0059] Step 1: Real-time acquisition of the temperature of the temperature detector 8 inside the energy storage box 1 and the state of charge of the battery pack;

[0060] Step 2: Obtain grid load demand and time-of-use electricity price signals, and set a preset temperature threshold range for the energy storage box 1;

[0061] Step 3: Dynamically adjust the charge and discharge power threshold of the energy storage box 1 according to the temperature data of the temperature detector 8, and reduce the charge and discharge rate when the temperature exceeds the safety threshold.

[0062] The working principle of the present invention is as follows: The upper end of the support frame 4 is used to house the energy storage battery. The influence of the external environment and the charging and discharging of the energy storage battery will cause the temperature inside the energy storage box 1 to change. Based on this, the temperature inside the energy storage box 1 needs to be controlled in real time. The batteries inside the energy storage box 1 are often in a stacked state. When the external ambient temperature is low, the heat of the stacked energy storage batteries is difficult to dissipate, so the temperature will rise. Therefore, in low ambient temperatures, no additional external heating or heat dissipation equipment is required. However, when the external ambient temperature is high, the stacked energy storage batteries will further increase in temperature during charging and discharging, so heat dissipation is required.

[0063] Based on the above description of the working principle, a spacing adjustment portion 5 is installed between each layer of support frames 4 and the adjacent support frames 4. When the ambient temperature is high, the gas inside sleeve 1 51 and sleeve 2 54 will expand due to the rising temperature, thereby increasing the spacing between each layer of support frames 4 and the adjacent support frames 4, improving the heat dissipation effect, thereby reducing the power dissipated by external equipment and saving energy. When the temperature inside the environment or the energy storage box 1 drops, the air pressure inside sleeve 1 51 and sleeve 2 54 will drop again, shortening the spacing between each layer of support frames 4 and the adjacent support frames 4, relatively bringing the stacked energy storage batteries closer together. The reduced gap can attenuate the heat dissipation effect, making the temperature of the stacked energy storage batteries relatively stable, reducing the power dissipated by external equipment and further saving energy. It should be noted that when the temperature in the external environment or the energy storage box 1 changes, the gap between the stacked energy storage batteries is changed mechanically. This purely mechanical method will not cause short circuits even under the influence of dust, and has a long service life.

[0064] It should be noted that since the energy storage tank 1 needs to maintain a relatively stable temperature range, and sleeve 1 51 and sleeve 2 54 are in a nested state, they need to maintain a sealed state during expansion and contraction. This requires a sealing ring 533, which can easily harden and lose its elasticity in dry conditions. To this end, the outer surface of layer 531 contacts the inner wall of sleeve 2 54, and the spring 535 and retaining plate 536 push lubricating oil into groove 2 538. As sleeve 1 51 and sleeve 2 54 expand and contract, the entire path of sealing ring 533's movement is lubricated by the lubricating oil in groove 2 538, extending the life of sealing ring 533 while maintaining expansion and contraction of sleeve 1 51 and sleeve 2 54.

[0065] It should also be noted that if Figure 9 As shown, sleeve 2 54 is separated from the outer cover 55, keeping sleeve 1 51 and sleeve 2 54 matched, and then the lubricating oil is injected from the filling hole 530 through the injection equipment, and the outer side of groove 2 538 is blocked by sleeve 2 54, so the inner cavity 534 can be filled with lubricating oil, which is convenient for subsequent maintenance. After filling with lubricating oil, sleeve 1 51 and sleeve 2 54 are installed, and then the air pump 2 is used to fill the inside of sleeve 1 51 and sleeve 2 54 with gas to complete the maintenance.

[0066] In addition, the air pressure detector in the sleeve 1 51 can monitor the change of air pressure in real time. If the air pressure drops to 0, the spacing adjustment part 5 is damaged. The spacing adjustment parts 5 on different layers are interconnected through the conductive tube 1 6 and the conductive tube 2 7, so that the air pressure inside each spacing adjustment part 5 is the same and connected. The air pump 2 is driven by the controller to generate gas inside the spacing adjustment part 5. Even if the spacing adjustment part 5 generates gas leakage, it can still support the support frame 4 and maintain the position of each spacing adjustment part 5 to a certain extent, providing valuable time for emergency repairs and avoiding excessive temperature inside the energy storage box 1.
