Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power supplies, and particularly to a battery compartment and its battery modules for temperature control regulation of energy storage power supplies. Background Art

[0002] With the rapid development of renewable energy and the continuous growth of power load, the demand for energy storage power supply battery compartments is also increasing. The energy storage power supply battery compartment mainly consists of a battery pack, a battery management system (BMS), and related auxiliary equipment and structural components. The battery pack is the core component for storing electrical energy, while the battery management system is responsible for monitoring the battery state, protecting the battery safety, optimizing the battery performance, etc. In addition, the battery compartment also needs to be equipped with an appropriate heat dissipation system, safety protection devices, etc., to ensure that the battery operates in a stable and safe environment.

[0003] Chinese Patent Invention No. 202410594071.2 proposes an energy storage battery compartment, including: a housing, the upper and lower ends of the housing are open structures, the upper end of the housing is fixedly connected with an upper air duct communicating with its interior, and the lower end of the housing is fixedly connected with a lower air duct communicating with its interior; a plurality of battery racks, a plurality of the battery racks are fixedly connected at equal intervals in the vertical direction inside the housing; a heat storage bin, the upper and lower ends of the heat storage bin are open structures, the heat storage bin is fixedly connected to one side of the housing, and its lower end is fixedly connected to the lower air duct communicating with its interior; an air conditioner, the upper and lower ends of the air conditioner are open structures, the air conditioner is fixedly connected to the other side of the housing, and its upper end is fixedly connected to the upper air duct communicating with its interior.

[0004] However, in this prior art, since the battery modules in the battery compartment are generally assembled by multiple single cells, there will be inconsistencies between the single cells. The problem of inconsistency is solved through battery equalization technology, that is, the single cells are charged and discharged separately to achieve the consistency of the capacity of the single cells. Therefore, when the single cells are charged and discharged, the increased temperatures are inconsistent, resulting in inconsistent degrees of heat dissipation required; in addition, since the single cells need to be ventilated and cooled separately, each single cell needs to be isolated first and then cooled specifically; this prior art cannot solve the above technical problems.

[0020] A blocking plate is arranged on the support frame, and the locking plate is lapped on the blocking plate.

[0021] The technical effects and advantages of the present invention:

[0022] 1. In the present invention, by arranging the closing assembly and the isolation plate, the support frame is divided into multiple spaces, so that each battery assembly is separately isolated, which is convenient for subsequent real-time monitoring of the temperature of each battery assembly and targeted cooling by the auxiliary ventilation assembly; by arranging the ventilation assembly, according to the detection results of the temperature sensors, the size of the ventilation volume is adjusted in real time, so as to achieve targeted cooling of the battery assemblies and meet the different heat dissipation requirements of the battery assemblies.

[0023] 2. In the present invention, by arranging the rotating shaft, the closing plate and the telescopic plate, the rotating shaft drives the closing plate to rotate, so that the adjacent two accommodating spaces are separated, ensuring that the battery assemblies are relatively isolated from each other and avoiding the mutual influence of the targeted cooling of the battery assemblies. By the mutual pressing of the telescopic plates, the sealing of the separated state of the accommodating space is ensured.

[0024] 3. In the present invention, by setting the left turning plate and the right turning plate to fit each other to form a complete ventilation hole, the position of the moving plate is adjusted in real time according to the temperature of the battery body measured by the temperature sensor, that is, the moving plate is controlled to reciprocally slide along the left turning plate to adjust the shielding amount of the ventilation hole; when the ventilation volume is insufficient, the left turning plate and the right turning plate can also be controlled to rotate clockwise synchronously to completely open the air inlet end of the accommodation space where the current battery body is located, increasing the air flow rate for heat exchange and ensuring timely heat dissipation and temperature reduction of the battery body.

[0025] 4. In the present invention, by setting the moving block, the fixed block, the support plate and the lifting support wheel, the moving block drives the battery body to smoothly enter the accommodation space through the support plate. While the lifting support wheel supports the movement of the battery body, it effectively reduces the friction force received by the battery body. At the same time, with the limitation of the traction block, it ensures that the battery body smoothly enters the accommodation space, avoiding collision of the battery body and causing damage to the edge, resulting in liquid leakage.

[0026] 5. In the present invention, when the temperature sensors on the battery bodies in two adjacent accommodation spaces detect that the temperature difference between the two is large and there is a situation where the temperature of one party is adjusted slowly, the closing components on the mutually close sides of the two accommodation spaces are controlled to open, enabling the air flow in the two accommodation spaces to communicate with each other, so that the temperatures in the two spaces compensate each other, accelerating the heating or cooling efficiency of the battery body and ensuring the temperature recovery efficiency of the battery body.

[0027] 6. In the present invention, by detecting in real time the change in the compression amount of the return spring during the rotation of the telescopic plate along with the closing plate, it is judged whether there is a bulging phenomenon in the current battery body; by detecting in real time the change in the compression amounts of the telescopic spring and the auxiliary spring, it is judged whether there is a liquid leakage situation in the current battery body, thereby controlling the moving block to push the battery body out of the accommodation space, enabling the bulging or liquid-leaking battery body to be quickly screened out by the staff and reducing the potential safety hazards during the use of the battery module.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] In order to solve the problem that after the individual cells in the battery module become inconsistent, charging and discharging the individual cells separately leads to inconsistent temperature rise of the individual cells, and the problem that when the individual cells need to be separately isolated for different degrees of temperature reduction due to inconsistent temperature rise, Embodiment 1 is proposed.

[0043] Embodiment 1:

[0044] The battery module in the battery compartment is generally assembled from multiple individual cells. Due to the internal differences or external usage states of the individual cells themselves, the situation of different capacities of the individual cells will occur, resulting in inconsistencies among the individual cells in the battery module. Over time, the inconsistencies of the individual cells will become larger and larger, thus affecting the overall performance and lifespan of the battery.

[0045] The problem of inconsistent individual cells is solved by battery equalization technology, that is, charging and discharging the individual cells separately to achieve the consistency of the capacities of the individual cells, thereby ensuring the overall performance of the battery. Therefore, when the individual cells are charged and discharged, the rising temperatures are inconsistent, resulting in inconsistent degrees of heat dissipation required; in addition, since the individual cells need to be separately ventilated and cooled, each individual cell needs to be isolated before targeted cooling.

[0046] As Figures 1 to 12 shown, the present invention provides a battery compartment for temperature control adjustment of an energy storage power supply, including a compartment body assembly 1, a wind supply assembly 2 is arranged on the compartment body assembly 1, a support frame 3 is arranged inside the compartment body assembly 1, the support frame 3 is formed by the mutual overlap of vertical columns and horizontal columns, and the vertical columns and horizontal columns overlap to form accommodation spaces with the same space size. A closing assembly 5 is arranged along the horizontal direction on both sides of the accommodation space, a handling assembly 6 is arranged at the bottom of the accommodation space, a ventilation assembly 7 is arranged at the rear end of the accommodation space, a partition plate 8 is arranged along the vertical direction at the top and bottom of the accommodation space, and traction blocks 9 are arranged on both sides of the front end of the accommodation space to limit the battery body 401 when it is pushed into the accommodation space and ensure the movement track of the battery body 401. A battery assembly 4 is placed on the support frame 3, closing assemblies 5 are arranged on both sides of the battery assembly 4, a handling assembly 6 is arranged at the bottom of the battery assembly 4, partition plates 8 are arranged above and below the battery assembly 4, a ventilation assembly 7 is arranged at the rear end of the battery assembly 4, traction blocks 9 are arranged on the support frame 3, and a temperature sensor is arranged on the battery assembly 4, and the temperature sensor is arranged on the battery body 401 to monitor the temperature of the battery body 401 in real time.

[0047] By setting the sealing component 5 in cooperation with the isolation plate 8, the support frame 3 is divided into multiple spaces, so as to isolate each battery component 4 individually, which is convenient for subsequent real-time monitoring of the temperature of each battery component 4 and targeted cooling of the auxiliary ventilation component 7; by setting the ventilation component 7, according to the detection results of the temperature sensor, the size of the ventilation volume is adjusted in real time, so as to achieve targeted cooling of the battery component 4 and meet the different heat dissipation requirements of the battery component 4.

[0048] To solve the above technical problems, as Figures 5 - 7 shown, in this embodiment, by setting the sealing component 5 in cooperation with the isolation plate 8, the separate isolation of the battery body 401 is realized. The sealing component 5 includes a rotating shaft 503. A sealing plate 501 is arranged on the outer side of the rotating shaft 503. Telescopic plates 502 are arranged at both ends of the sealing plate 501. One end of the telescopic plate 502 extends into the interior of the sealing plate 501 and is connected to the inner end of the sealing plate 501 through a return spring; strip-shaped holes are formed at both ends of the sealing plate 501. One end of the telescopic plate 502 is located in the strip-shaped hole and can slide along the inner wall of the strip-shaped hole. One end of the return spring (not shown in the figure) is fixedly connected to the inner end of the strip-shaped hole, and the other end is fixedly connected to the end of the telescopic plate 502. When the sealing plate 501 is parallel to the transverse column, the telescopic plates 502 at the ends of the sealing plate 501 are in a state of being pressed against each other, so that the sealing and isolation effect of the sealing plate 501 is better. The sealing component 5 further includes fixing plates 508 arranged on both sides. The fixing plates 508 are fixedly arranged on the support frame 3. A power part is arranged on the top of the fixing plate 508. The power part can adopt a variety of driving methods. In this embodiment, the power drive in the sealing component 5 is realized by the cooperation of a gear and a rack; the power part includes a driving motor 505, a driving gear 506 and a long rack 507. The output end of the driving motor 505 is fixedly provided with the driving gear 506. The driving gear 506 is meshed with the long rack 507; a driven gear 504 is fixedly arranged on the top of the rotating shaft 503. The driven gear 504 is meshed with the long rack 507.

[0049] During use, by controlling the driving motor 505 to drive the driving gear 506 to rotate, the driving gear 506 drives the long rack 507 to move, thereby driving the driven gear 504 to rotate. The driven gear 504 drives the rotating shaft 503 to rotate, thereby driving the sealing plate 501 to rotate. When the sealing plate 501 rotates to a state parallel to the transverse column, at this time, the return spring generates a compression amount, and its elastic force assists the ends of the sealing plate 501 to remain in a state of being pressed against each other, ensuring the isolation effect.

[0050] By setting the rotating shaft 503, the closing plate 501 and the telescopic plate 502, the rotating shaft 503 drives the closing plate 501 to rotate, so that adjacent two accommodating spaces are separated, ensuring that the battery modules 4 are relatively isolated from each other, avoiding the mutual influence of the targeted cooling of the battery modules 4, and ensuring the sealing of the separated state of the accommodating space by the mutual pressing of the telescopic plates 502.

[0051] As Figure 8 shown, in this embodiment, the ventilation component 7 is set to adjust the degree of ventilation and heat dissipation in real time. The ventilation component 7 is arranged at the connection of the air supply pipe 202 and the support frame 3. The air flow in the air supply pipe 202 enters the accommodating space through the ventilation component 7 and exchanges heat with the battery module 4 for cooling. The ventilation component 7 includes a left rotating plate 702 and a right rotating plate 703. Ventilation holes are arranged on the left rotating plate 702 and the right rotating plate 703, and each of the left rotating plate 702 and the right rotating plate 703 is provided with half of the ventilation holes. When the two are parallel, the ventilation holes are complete circles. A moving plate 704 is movably arranged on one side of the left rotating plate 702; the ventilation component 7 further includes a fixed frame 701. The ventilation component 7 is fixedly installed at the rear end of the accommodating space through the fixed frame 701. The fixed frame 701 is fixedly connected to the support frame 3. The left rotating plate 702 and the right rotating plate 703 are rotatably connected to the fixed frame 701. Rotating shafts are arranged at the top and bottom of the left rotating plate 702 and the right rotating plate 703, and they are rotatably connected to the fixed frame 701 through the rotating shafts. A power structure is connected to the rotating shaft at the top, and the power structure is used to drive the left rotating plate 702 and the right rotating plate 703 to rotate. This power structure can refer to the power part of the closing component 5, but is not limited to the driving method of the power part; a connecting plate 706 is arranged on the top of the moving plate 704. One side of the connecting plate 706 is fixedly connected to a micro telescopic cylinder 705. The micro telescopic cylinder 705 is fixedly connected to the left rotating plate 702. The moving plate 704 is slidably connected to the left rotating plate 702; a groove is arranged on the left rotating plate 702, and a horizontal convex strip is arranged on the moving plate 704. The horizontal convex strip is clamped in the groove and can slide back and forth along the groove.

[0052] During use, the battery temperature is divided into a normal range and a high temperature range. According to the temperature change of the battery body 401 detected by the temperature sensor, the telescopic amount of the output end of the micro telescopic cylinder 705 is controlled.

[0053] When the temperature sensor detects that the temperature of the current battery body 401 is at the highest value in the high temperature range, control the output end of the micro telescopic cylinder 705 to maintain the longest elongation amount, that is Figure 8In the state shown, it is ensured that air can enter the accommodation space from the air supply pipe 202 to exchange heat with the battery body 401; when the temperature sensor detects that the temperature of the current battery body 401 decreases, the output end of the micro telescopic cylinder 705 retracts, driving the moving plate 704 to translate along the left turning plate 702 to block the ventilation holes, reducing the air flow rate, thereby reducing the degree of ventilation heat exchange and avoiding damage caused by excessive heat exchange and cooling resulting in too low a temperature of the battery body 401; when the temperature sensor detects that the temperature of the current battery body 401 is at the minimum value of the normal range, it means that the battery temperature is about to enter the low temperature state and ventilation heat exchange needs to be stopped for heat preservation. Control the output end of the micro telescopic cylinder 705 to retract until the moving plate 704 drives to completely block the ventilation holes. At this time, the heat exchange stops and the battery body 401 is heat-preserved; when the temperature sensor detects that the temperature of the current battery body 401 exceeds the highest value of the high temperature range, it means that the battery body 401 can no longer be effectively cooled and heat-exchanged only by the air flow through the ventilation holes. At this time, the output end of the micro telescopic cylinder 705 is at the longest extension amount. The left turning plate 702 and the right turning plate 703 are controlled to rotate clockwise simultaneously through the power structure. The moving plate 704 rotates with the left turning plate 702, so that the left turning plate 702 and the right turning plate 703 rotate to a state parallel to the transverse column, opening the air inlet end of the accommodation space, enabling the air flow to fully enter the accommodation space to exchange heat with the battery body 401 and quickly cool down.

[0054] By setting the left turning plate 702 and the right turning plate 703 to fit each other to form a complete ventilation hole, according to the temperature of the battery body 401 measured by the temperature sensor, the position of the moving plate 704 is adjusted in real time, that is, the moving plate 704 is controlled to reciprocally slide along the left turning plate 702 to adjust the blocking amount of the ventilation hole; when the ventilation volume is insufficient, the left turning plate 702 and the right turning plate 703 can also be controlled to rotate clockwise synchronously to completely open the air inlet end of the accommodation space where the current battery body 401 is located, increasing the air flow rate for heat exchange, and ensuring that the battery body 401 dissipates heat and cools down in time.

[0055] Due to the relatively heavy weight of the battery body 401, it is difficult for the staff to push and place it into the accommodation space at a high position on the support frame 3, and the battery body 401 will shift during the pushing process, resulting in the battery body 401 colliding with the side of the accommodation space, thereby causing damage to the edge of the battery body 401 and further resulting in liquid leakage.

[0056] To solve the above technical problems, in this embodiment, as Figures 9 - 10As shown, by setting the consignment component 6 to assist the battery body 401 to enter the accommodation space, the consignment component 6 includes symmetrically arranged moving blocks 602. Through holes are provided on the moving blocks 602, and threads that match the threads on the screw 601 are provided in the through holes. The screw 601 is threadedly connected to the moving block 602. A tray 603 is provided on the opposite side of the moving block 602. A lifting column 604 is provided at the bottom of the tray 603. The lifting column 604 is slidably arranged on the moving block 602 and lifts along the moving block 602. A telescopic spring 605 is provided outside the lifting column 604. When the battery body 401 presses on the tray 603, the lifting column 604 lifts and compresses the telescopic spring 605; one end of the screw 601 is rotatably connected to a fixed block 606. There is no thread in the fixed block 606. The fixed block 606 is fixedly arranged on the support frame 3. Lifting supporting wheels 607 are provided on the opposite side of the fixed block 606. When the battery body 401 moves into the accommodation space, the lifting supporting wheels 607 roll to assist the movement of the battery body 401 and reduce the friction. A lifting plate 608 is rotatably connected to the lifting supporting wheels 607. Lifting shafts 609 are fixedly provided at both ends of the lifting plate 608. The lifting shafts 609 are slidably arranged on the fixed block 606 and lift along the fixed block 606. An auxiliary spring 610 is provided outside the lifting shafts 609. When the battery body 401 presses on the lifting supporting wheels 607, the lifting shafts 609 lift and compress the auxiliary spring 610; one end of any screw 601 away from the fixed block 606 is fixedly connected to a driving pulley 611, and one end of the other screw 601 away from the fixed block 606 is fixedly connected to a driven pulley 614. A belt 613 is wound around the driving pulley 611 and the driven pulley 614. A consignment motor 612 is fixedly provided on the driving pulley 611.

[0057] During use, in the initial state, the moving block 602 is in contact with the fixed block 606. The tail end of the battery body 401 is placed on the tray 603 and the lifting supporting wheels 607 to compress the telescopic spring 605 and the auxiliary spring 610. This serves as the starting signal for the consignment motor 612. The consignment motor 612 drives the screw 601 to rotate, thereby driving the moving block 602 to move. The moving block 602 drives the battery body 401 to move into the accommodation space. The battery body 401 drives the lifting supporting wheels 607 to continuously roll until the moving block 602 moves to the tail end of the accommodation space, as Figure 9 shown in the position. At this time, stop the rotation of the consignment motor 612, and the battery body 401 has been placed in place.

[0058] By setting the moving block 602, the fixed block 606, the pallet 603 and the lifting supporting wheel 607, the moving block 602 drives the battery body 401 to smoothly enter the accommodation space through the pallet 603. While supporting the movement of the battery body 401, the lifting supporting wheel 607 effectively reduces the friction force received by the battery body 401. At the same time, with the limit of the traction block 9, it is ensured that the battery body 401 smoothly enters the accommodation space, avoiding the collision of the battery body 401 and resulting in damage to the edge, thus causing liquid leakage.

[0059] As Figure 2 and Figure 11 shown, in this embodiment, by setting the air supply assembly 2 to supply a heat exchange air flow to the accommodation space, the air supply assembly 2 includes an air inlet box 201. The air inlet box 201 is arranged on the top of the bin body assembly 1. A air supply pipe 202 is connected to the bottom of the air inlet box 201. The air supply pipe 202 extends into the interior of the bin body assembly 1 and is fixedly connected to the support frame 3. A cross beam 203 is fixedly arranged in the air inlet box 201. Electric fans 204 are uniformly arranged on the cross beam 203. Air inlet grilles 205 are arranged on both sides of the air inlet box 201. Heating plates and refrigeration plates can be arranged on the top of the air inlet box 201 and on both sides perpendicular to the air inlet grilles 205, which is convenient for cooperating with the air supply assembly 2 to input cold and hot air flows and assist in maintaining the temperature of the battery body 401 in the accommodation space; the bin body assembly 1 includes a container 101. The side of the container 101 is uniformly provided with a box door 102. A pull rod 103 is arranged on the box door 102. A handle 104 is arranged on the pull rod 103. A lock catch 105 is arranged on the side of the container 101. An air outlet grille 106 is arranged on the box door 102.

[0060] During use, the electric fans 204 are turned on to suck the external air flow into the air inlet box 201. The air flow enters the air supply pipe 202 through the electric fans 204, and then enters the accommodation space through the ventilation holes on the left turning plate 702 and the right turning plate 703 in the ventilation assembly 7. After exchanging heat with the battery body 401, the air flow is output from the air outlet grille 106 on the box door 102, completing the heat exchange and cooling of the battery body 401.

[0061] The flow direction of the heat exchange air flow is: air inlet grille 205 - air inlet box 201 - air supply pipe 202 - the rear end of the support frame 3 - the ventilation holes on the ventilation assembly 7 - the accommodation space of the support frame 3 - the front end of the support frame 3 - box door 102 - air outlet grille 106.

[0062] As Figure 12As shown in the figure, the present invention also proposes a battery module, which includes the above-mentioned battery assembly 4. The support frame 3 is provided with accommodation spaces arranged in an array, and the battery assembly 4 is placed in the accommodation spaces. The battery assemblies 4 are arranged in an array to form a battery module. The battery assembly 4 includes a battery body 401. A locking plate 402 is rotatably provided at the front end of the battery body 401. A locking motor is provided on the locking plate 402. A pull ring 403 is fixedly provided at the front end of the battery body 401. Workers can drag the battery body 401 through the pull ring 403, or perform actions such as lifting it to a high altitude. The locking motor drives the locking plate 402 to rotate, so that the locking plate 402 is lapped on the blocking plate 10 to fix the battery body 401. A blocking plate 10 is provided on the support frame 3, and the locking plate 402 is lapped on the blocking plate 10.

[0063] The working principle of the present invention: First, place the battery body 401 into the accommodation space and fix it. Specifically: Workers lift the battery body 401 through the pull ring 403, and then place the tail end of the battery body 401 on the support plate 603 and the lifting support wheel 607, compress the telescopic spring 605 and the auxiliary spring 610, start the handling motor 612, the handling motor 612 drives the screw rod 601 to rotate, thereby driving the moving block 602 to move. The moving block 602 drives the battery body 401 to move into the accommodation space. The battery body 401 drives the lifting support wheel 607 to continuously roll until the moving block 602 moves to the tail end of the accommodation space. At this time, stop the rotation of the handling motor 612, and the battery body 401 has been placed in place. Then, control the locking motor to drive the locking plate 402 to rotate, so that the locking plate 402 can be lapped on the blocking plate 10 to fix the battery body 401.

[0064] Secondly, turn on the air supply component 2 to cooperate with the ventilation component 7 to achieve targeted cooling and heat dissipation. Specifically: Turn on the electric fan 204 to suck the external air flow into the air inlet box 201. The air flow passes through the electric fan 204 and enters the air supply pipe 202, and then enters the accommodation space through the ventilation holes on the left-turn plate 702 and the right-turn plate 703 in the ventilation component 7. After exchanging heat with the battery body 401, the air flow is output from the air outlet grille 106 on the box door 102 to complete the heat exchange and cooling of the battery body 401. The flow direction of the heat exchange air flow is: air inlet grille 205 - air inlet box 201 - air supply pipe 202 - the rear end of the support frame 3 - the ventilation holes on the ventilation component 7 - the accommodation space of the support frame 3 - the front end of the support frame 3 - the box door 102 - air outlet grille 106.

[0065] Finally, adjust the ventilation volume of each battery body 401 according to the temperature sensor on the battery body 401. Specifically: Divide the battery temperature into a normal range and a high-temperature range, and control the telescopic amount of the output end of the micro telescopic cylinder 705 according to the temperature change of the battery body 401 detected by the temperature sensor.

[0066] When the temperature sensor detects that the temperature of the current battery body 401 is at the maximum value of the high-temperature range, control the output end of the micro telescopic cylinder 705 to maintain the longest elongation, that is Figure 8 the state shown in, ensure that the air flow can enter the accommodation space from the air supply pipe 202 to exchange heat with the battery body 401; when the temperature sensor detects that the temperature of the current battery body 401 decreases, control the output end of the micro telescopic cylinder 705 to retract, drive the moving plate 704 to translate along the left-turning plate 702, block the ventilation holes, reduce the air flow, and avoid damage to the battery body 401 caused by excessive heat exchange and cooling; when the temperature sensor detects that the temperature of the current battery body 401 is at the minimum value of the normal range, it means that the battery temperature is about to enter the low-temperature state, and ventilation and heat exchange need to be stopped for heat preservation. Control the output end of the micro telescopic cylinder 705 to retract until the moving plate 704 completely blocks the ventilation holes. At this time, the heat exchange stops and the battery body 401 is heat-preserved; when the temperature sensor detects that the temperature of the current battery body 401 exceeds the maximum value of the high-temperature range, it means that the battery body 401 can no longer effectively cool and exchange heat only through the ventilation holes by air flow. At this time, the output end of the micro telescopic cylinder 705 is at the longest elongation. Control the left-turning plate 702 and the right-turning plate 703 to rotate clockwise at the same time through the power structure. The moving plate 704 rotates with the left-turning plate 702, so that the left-turning plate 702 and the right-turning plate 703 rotate to a state parallel to the transverse column, open the air inlet end of the accommodation space, and make the air flow fully enter the accommodation space to exchange heat with the battery body 401 and quickly cool down.

[0067] Based on the technical solution of the above-mentioned Embodiment 1, when the temperature difference between the battery bodies 401 in two adjacent accommodation spaces is relatively large, that is, when either one of the two cools down or warms up too much, it is impossible to quickly exchange heat or warm up in a short time, resulting in a slow temperature recovery speed of the battery body 401; in addition, when a bulge or liquid leakage occurs on the battery body 401, it cannot be identified and distinguished in time, resulting in potential safety hazards during the use of the battery module; furthermore, Embodiment 2 is proposed to solve the above technical problems.

[0068] Embodiment 2:

[0069] In two adjacent accommodation spaces, when both battery bodies 401 are within the normal range and the high-temperature range, but the temperature difference is relatively large, resulting in a faster temperature adjustment of one battery body 401 and the inability to quickly adjust the temperature of the other battery body 401 in a short time, thus resulting in a slow temperature recovery speed of the battery body 401.

[0070] To solve the above technical problems, when the temperature sensor identifies that the temperatures of the battery bodies 401 in two adjacent accommodation spaces differ significantly, the closing components 5 on the sides close to each other in the two accommodation spaces are controlled to open at this time, so that the airflows in the two accommodation spaces communicate with each other. Specifically: the control drive motor 505 drives the long rack 507 to move through the driving gear 506, the long rack 507 drives the driven gear 504 to rotate, the driven gear 504 drives the rotating shaft 503 to rotate, thereby driving the closing plate 501 to rotate. When the closing plate 501 rotates to a state perpendicular to the transverse column, at this time, the two accommodation spaces are in a communicating state, and the airflows communicate with each other and compensate each other, thereby accelerating the heat exchange and cooling or heating efficiency of the battery body 401.

[0071] When the temperature sensors on the battery bodies 401 in two adjacent accommodation spaces detect that the temperature difference between the two is large and there is a situation where the temperature adjustment of one side is slow, the closing components 5 on the sides close to each other in the two accommodation spaces are controlled to open, so that the airflows in the two accommodation spaces communicate with each other, so that the temperatures in the two spaces compensate each other, accelerating the heating or cooling efficiency of the battery body 401 and ensuring the temperature recovery efficiency of the battery body 401.

[0072] During the long-term charge and discharge process of the battery body 401, the battery body 401 may bulge or leak due to various factors. The prior art cannot assist the staff to identify and screen it in time, resulting in potential safety hazards in the use of the battery module composed of the battery body 401.

[0073] During the opening process of the above-mentioned closing component 5, while the closing plate 501 rotates, it drives the telescopic plate 502 to rotate. During the rotation of the end of the telescopic plate 502, it can contact the side of the battery body 401, causing the return spring to generate a compression amount. The compression amount of the return spring can be used to judge whether the current battery body 401 has a bulging phenomenon. Specifically: when the compression amount of the return spring changes consistently with the rotation of the telescopic plate 502, it means that there is no bulging phenomenon on the surface of the current battery body 401; when the compression amount of the return spring changes inconsistently and the compression amount of some return springs is greater than that of the other return springs, it means that the current battery body 401 has a bulging phenomenon and should be screened out.

[0074] The screening process is as follows: First, the control center issues an alarm to notify the staff. Second, the control locks the motor to drive the locking plate 402 to rotate, so that the locking plate 402 leaves the blocking plate 10, releasing the fixation of the battery body 401. Then, the control consigns the motor 612 to drive the screw rod 601 to rotate, thereby driving the battery body 401 to move a certain distance outside the accommodation space through the moving block 602, so that the bulged battery body 401 protrudes from the other battery bodies 401. Finally, the staff opens the box door 102, and with the assistance of the moving block 602, quickly extracts the bulged battery body 401.

[0075] Judge whether the current battery body 401 has a liquid leakage situation through the change in the compression amount of the telescopic spring 605 and the auxiliary spring 610. Specifically: After the battery body 401 is fixed in the accommodation space, the telescopic spring 605 and the auxiliary spring 610 are evenly distributed at the four corners of the battery body 401, and the compression amount remains the same. The control center records the compression amount at this time. When the overall compression amount of the telescopic spring 605 and the auxiliary spring 610 decreases or partially decreases, it means that the battery body 401 has a liquid leakage at this time, resulting in a decrease in the weight of the battery body 401, thereby causing the overall compression amount of the telescopic spring 605 and the auxiliary spring 610 to decrease or the partial compression amount to decrease due to weight bias. At this time, the leaking battery body 401 needs to be screened out. Screening is carried out through the above screening process.

[0076] By detecting in real time the change in the compression amount of the return spring during the rotation of the telescopic plate 502 as the closing plate 501 rotates, to judge whether the current battery body 401 has a bulging phenomenon; by detecting in real time the change in the compression amount of the telescopic spring 605 and the auxiliary spring 610, to judge whether the current battery body 401 has a liquid leakage situation, so as to control the moving block 602 to push the battery body 401 out of the accommodation space, so that the bulged or leaking battery body 401 can be quickly screened out by the staff, reducing the potential safety hazards during the use of the battery module.

[0077] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
