[0002] With the rapid development of renewable energy and the continuous growth of power load, the demand for energy storage battery warehouses is also increasing. Energy storage battery warehouses are mainly composed of battery packs, battery management systems (BMS) and related auxiliary equipment and structural parts. The battery pack is the core component for storing electrical energy, while the battery management system is responsible for monitoring the battery status, protecting battery safety, optimizing battery performance, etc. In addition, the battery warehouse also needs to be equipped with appropriate cooling systems, safety protection devices, etc. to ensure that the battery operates in a stable and safe environment.

[0004] However, in the prior art, since the battery module in the battery compartment is generally assembled from multiple single cells, inconsistency will occur between the single cells.

[0015] Technical effects and advantages of the present invention: 1. In the present invention, a closed component is provided in conjunction with an isolation plate to divide the support frame into a plurality of spaces, thereby isolating each battery component individually, which is convenient for subsequent real-time monitoring of the temperature of each battery component and targeted cooling by an auxiliary ventilation component; by providing a ventilation component, the ventilation volume is adjusted in real time according to the detection result of the temperature sensor, thereby achieving targeted cooling of the battery component and meeting different heat dissipation requirements of the battery component.

[0017] 3. In the present invention, a complete ventilation hole is formed by arranging the left-turn plate and the right-turn plate to fit each other. According to the temperature of the battery body measured by the temperature sensor, the position of the movable plate is adjusted in real time, that is, the movable plate is controlled to slide back and forth along the left-turn plate to adjust the blocking amount of the ventilation hole; when the ventilation volume is insufficient, the left-turn plate and the right-turn 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, thereby increasing the air flow for heat exchange and ensuring that the battery body dissipates heat and cools down in time.

[0018] 4.

[0019] 5.

[0020] 6. In the present invention, by real-time detecting the change in the compression amount of the reset spring during the rotation of the telescopic plate with the closing plate, it is determined whether the current battery body has a bulging phenomenon; by real-time detecting the change in the compression amount of the telescopic spring and the auxiliary spring, it is determined whether the current battery body has a leakage, thereby controlling the moving block to push the battery body out of the accommodating space, so that the bulging or leaking battery body can be quickly screened out by the staff, reducing the safety hazards of the battery module during use.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] In order to solve the problem of inconsistent temperature rise of single cells in a battery module caused by charging and discharging the single cells separately, and the problem of isolating the single cells separately and cooling them to different degrees due to the inconsistent temperature rise, embodiment 1 is proposed.

[0025] Embodiment 1: The battery module in the battery compartment is generally assembled from multiple single cells. Due to the internal differences of the single cells themselves or different external usage conditions, the capacities of the single cells will be different, resulting in inconsistencies between the single cells in the battery module. As time accumulates, the inconsistency of the single cells will become greater and greater, thus affecting the overall performance and life of the battery.

[0026] The problem of cell inconsistency is solved by battery balancing technology, that is, charging and discharging the cells separately to achieve the consistency of the cell capacity, thereby ensuring the overall performance of the battery. Therefore, when charging and discharging, the temperature of the cells is inconsistent, resulting in inconsistent heat dissipation. In addition, since the cells need to be ventilated and cooled separately, each cell needs to be isolated and cooled in a targeted manner.

[0027] like Figures 1 to 12 As shown, the present invention provides a battery bin for temperature control and regulation of energy storage power supply, including a bin body assembly 1, an air supply assembly 2 is arranged on the bin body assembly 1, a support frame 3 is arranged in the bin body assembly 1, the support frame 3 is formed by vertical columns and horizontal columns overlapping each other, the vertical columns and the horizontal columns are overlapped to form a storage space of uniform size, a closing assembly 5 is arranged on both sides of the storage space along the horizontal direction, a shipping assembly 6 is arranged at the bottom of the storage space, a ventilation assembly 7 is arranged at the rear end of the storage space, an isolation plate 8 is arranged at the top and bottom of the storage space along the vertical direction, and a traction block 9 is arranged on both sides of the front end of the storage space, and when the battery body 401 is pushed into the storage space, it is limited to ensure the moving trajectory 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 shipping assembly 6 is arranged at the bottom of the battery assembly 4, isolation 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, a traction block 9 is arranged on the support frame 3, 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.

[0028] By setting up a closing component 5 in conjunction with an isolation plate 8, the support frame 3 is divided into multiple spaces, so that each battery component 4 can be individually isolated, which is convenient for subsequent real-time monitoring of the temperature of each battery component 4 and targeted cooling by the auxiliary ventilation component 7; by setting up the ventilation component 7, the ventilation volume is adjusted in real time according to the detection result of the temperature sensor, thereby achieving targeted cooling of the battery component 4 and meeting the different heat dissipation requirements of the battery component 4.

[0029] In order to solve the above technical problems, Figure 5-Figure 7As shown, in this embodiment, a closing component 5 is provided in cooperation with an isolation plate 8 to achieve separate isolation of the battery body 401. The closing component 5 includes a rotating shaft 503, a closing plate 501 is provided on the outer side of the rotating shaft 503, and telescopic plates 502 are provided at both ends of the closing plate 501. One end of the telescopic plate 502 extends into the interior of the closing plate 501 and is connected to the inner end of the closing plate 501 through a reset spring; strip holes are provided at both ends of the closing plate 501, one end of the telescopic plate 502 is located in the strip hole and can slide along the inner wall of the strip hole, one end of the reset spring (not shown in the figure) is fixedly connected to the inner end of the strip hole, and the other end of the reset spring is fixedly connected to the end of the telescopic plate 502. When the closing plate 501 remains parallel to the transverse column, the telescopic plates 502 at the ends of the closing plate 501 are in a state of being pressed against each other, so that the closing and isolation effect of the closing plate 501 is better. The closing component 5 also includes fixed plates 508 arranged on both sides, and the fixed plates 508 are fixedly arranged on the support frame 3. A power unit is arranged on the top of the fixed plate 508. The power unit can adopt a variety of driving methods. In this embodiment, the power drive is realized by gear rack cooperation in the closing component 5; the power unit 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 a driving gear 506, and the driving gear 506 is meshedly connected with the long rack 507; the top of the rotating shaft 503 is fixedly provided with a driven gear 504, and the driven gear 504 is meshedly connected with the long rack 507.

[0030] When in use, the driving motor 505 is controlled to drive the active gear 506 to rotate, and the active gear 506 drives the long rack 507 to move, thereby driving the driven gear 504 to rotate, and the driven gear 504 drives the rotating shaft 503 to rotate, thereby driving the closing plate 501 to rotate. The closing plate 501 rotates to a state parallel to the horizontal column. At this time, the reset spring produces a compression amount, and its elastic force assists the ends of the closing plate 501 to maintain a state of being pressed against each other, thereby ensuring the isolation effect.

[0031] 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 two adjacent accommodating spaces are separated, ensuring that the battery components 4 remain relatively isolated, avoiding the targeted cooling of the battery components 4 from affecting each other, and the telescopic plates 502 are pressed against each other to ensure the closed state of the separated accommodating spaces.

[0032] like Figure 8As shown, in this embodiment, the degree of ventilation and heat dissipation is adjusted in real time by setting a ventilation component 7. The ventilation component 7 is set at the connection between the air supply pipe 202 and the support frame 3. The airflow in the air supply pipe 202 enters the accommodating space through the ventilation component 7, and exchanges heat with the battery assembly 4 for cooling. The ventilation component 7 includes a left turn plate 702 and a right turn plate 703. The left turn plate 702 and the right turn plate 703 are provided with ventilation holes. The left turn plate 702 and the right turn plate 703 are respectively provided with half of the ventilation holes. When the two are parallel, the ventilation holes are complete circles. A movable plate 704 is movably provided on one side of the left turn plate 702; the ventilation component 7 also 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 turn plate 7 02 and the right turn plate 703 are rotatably connected to the fixed frame 701, the top and bottom ends of the left turn plate 702 and the right turn plate 703 are provided with a rotating shaft, which is rotatably connected to the fixed frame 701 through the rotating shaft, and the rotating shaft at the top is connected with a power structure, which is used to drive the left turn plate 702 and the right turn plate 703 to rotate. The power structure can refer to the power part of the closed component 5, but is not limited to the driving method of the power part; a connecting plate 706 is provided on the top of the movable plate 704, and a micro-telescopic cylinder 705 is fixedly connected to one side of the connecting plate 706, and the micro-telescopic cylinder 705 is fixedly connected to the left turn plate 702, and the movable plate 704 is slidably connected to the left turn plate 702; a groove is provided on the left turn plate 702, and a transverse convex strip is provided on the movable plate 704, which is clamped in the groove and can slide back and forth along the groove.

[0033] When in use, the battery temperature is divided into a normal range and a high temperature range, and the extension and retraction amount of the output end of the micro telescopic cylinder 705 is controlled according to the temperature change of the battery body 401 detected by the temperature sensor.

[0034] When the temperature sensor detects that the temperature of the current battery body 401 is at the highest value in the high temperature range, the output end of the micro telescopic cylinder 705 is controlled to maintain the maximum extension, that is, Figure 8, ensuring that the airflow 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 is reduced, the output end of the micro telescopic cylinder 705 is controlled to retract, driving the moving plate 704 to translate along the left turning plate 702, blocking the ventilation hole, reducing the air flow, thereby reducing the degree of ventilation and heat exchange, and avoiding excessive heat exchange and cooling that causes the battery body 401 to be damaged by low temperature; 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 a low temperature state, and it is necessary to stop ventilation and heat exchange for heat preservation, and control the output end of the micro telescopic cylinder 705 to retract until the battery body 401 is cooled. The movable plate 704 completely blocks the ventilation holes. At this time, the heat exchange stops and the battery body 401 is kept warm. When the temperature sensor detects that the temperature of the current battery body 401 drops beyond the highest value in the high temperature range, it means that the battery body 401 can no longer effectively cool down and exchange heat by relying solely on the airflow through the ventilation holes. At this time, the output end of the micro-telescopic cylinder 705 is at its longest extension. The power structure controls the left turn plate 702 and the right turn plate 703 to rotate clockwise at the same time. The movable plate 704 rotates with the left turn plate 702, so that the left turn plate 702 and the right turn plate 703 rotate to a state parallel to the horizontal column, opening the air inlet end of the accommodating space, so that the airflow fully enters the accommodating space to exchange heat with the battery body 401 and quickly cools down.

[0035] The left-turn plate 702 and the right-turn plate 703 are arranged to fit together to form a complete ventilation hole. The position of the movable plate 704 is adjusted in real time according to the temperature of the battery body 401 measured by the temperature sensor, that is, the movable plate 704 is controlled to slide back and forth along the left-turn plate 702 to adjust the blocking amount of the ventilation hole. When the ventilation volume is insufficient, the left-turn plate 702 and the right-turn 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, thereby increasing the air flow for heat exchange and ensuring that the battery body 401 dissipates heat and cools down in time.

[0036] Due to the heavy weight of the battery body 401, it is difficult for the staff to push it into the storage space located high up on the support frame 3, and the battery body 401 will shift during the pushing process, causing the battery body 401 to collide with the side of the storage space, thereby causing damage to the edge of the battery body 401, and further causing leakage.

[0037] In order to solve the above technical problems, in this embodiment, Figure 9-10As shown, by setting a shipping component 6 to assist the battery body 401 to enter the accommodating space, the shipping component 6 includes a symmetrically arranged moving block 602, a through hole is arranged on the moving block 602, a thread that matches the thread on the screw 601 is arranged in the through hole, the moving block 602 is threadedly connected with the screw 601, a support plate 603 is arranged on the opposite side of the moving block 602, a lifting column 604 is arranged at the bottom of the support plate 603, the lifting column 604 is slidably arranged on the moving block 602, and is lifted and lowered along the moving block 602, and a telescopic spring 605 is arranged on the outside of the lifting column 604, when the battery body 401 is pressed onto the support plate 603, the lifting column 604 is lifted and lowered, compressing 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, and a lifting column 604 is arranged on the opposite side of the fixed block 606 The supporting wheel 607 rolls when the battery body 401 moves into the accommodating space, assisting the battery body 401 to move and reducing friction. The lifting supporting wheel 607 is rotatably connected to a lifting plate 608, and lifting shafts 609 are fixedly arranged at both ends of the lifting plate 608. The lifting shaft 609 is slidably arranged on the fixed block 606 and is lifted and lowered along the fixed block 606. An auxiliary spring 610 is arranged on the outer side of the lifting shaft 609. When the battery body 401 is pressed onto the lifting supporting wheel 607, the lifting shaft 609 is lifted and lowered, compressing 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 the other end of the screw 601 away from the fixed block 606 is fixedly connected to a passive pulley 614. The driving pulley 611 and the passive pulley 614 are wound with a belt strip 613, and a shipping motor 612 is fixedly arranged on the driving pulley 611.

[0038] When in use, in the initial state, the moving block 602 is attached to the fixed block 606, the tail end of the battery body 401 is placed on the support plate 603 and the lifting support wheel 607, the telescopic spring 605 and the auxiliary spring 610 are compressed, and this is used as a starting signal for the transport motor 612, the transport 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, and the battery body 401 drives the lifting support wheel 607 to continue rolling until the moving block 602 moves to the tail end of the accommodation space, as shown in FIG. Fig. 9 The position shown, at this time, the rotation of the shipping motor 612 is stopped and the battery body 401 has been placed in place.

[0039] By setting the moving block 602, the fixed block 606, the support plate 603 and the lifting wheel 607, the moving block 602 drives the battery body 401 to smoothly enter the storage space through the support plate 603. The lifting wheel 607 effectively reduces the friction force on the battery body 401 while supporting the movement of the battery body 401, and cooperates with the limiting of the traction block 9 to ensure that the battery body 401 smoothly enters the storage space, avoiding collision of the battery body 401 and causing damage to the edge, thereby causing leakage.

[0040] like Figure 2 as well as Fig.11 As shown, in this embodiment, an air supply component 2 is provided to provide a heat exchange airflow to the accommodation space, and the air supply component 2 includes an air inlet box 201, which is arranged on the top of the warehouse body component 1, and the bottom of the air inlet box 201 is connected to an air supply pipe 202, which extends into the interior of the warehouse body component 1 and is fixedly connected to the support frame 3. A crossbeam 203 is fixedly provided in the air inlet box 201, and electric fans 204 are evenly provided on the crossbeam 203. Air inlet grilles 205 are provided on both sides of the air inlet box 201. A heating plate and a cooling plate can be arranged on the top and on both sides perpendicular to the air inlet grille 205, so as to cooperate with the air supply assembly 2 to input hot and cold airflows and assist in maintaining the temperature of the battery body 401 in the accommodation space; the warehouse assembly 1 includes a container 101, and doors 102 are evenly arranged on the sides of the container 101, and a pull rod 103 is arranged on the door 102, and a handle 104 is arranged on the pull rod 103, a lock 105 is arranged on the side of the container 101, and an air outlet grille 106 is arranged on the door 102.

[0041] When in use, 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 duct 202, and then passes through the ventilation holes on the left turn plate 702 and the right turn plate 703 in the ventilation assembly 7 to enter the storage space. 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.

[0042] The flow direction of the heat exchange airflow is: air inlet grille 205 - air inlet box 201 - air supply pipe 202 - rear end of the support frame 3 - ventilation holes on the ventilation assembly 7 - accommodating space of the support frame 3 - front end of the support frame 3 - box door 102 - air outlet grille 106.

[0043] like Fig.12As shown, the present invention also proposes a battery module, including the above-mentioned battery assembly 4, an array of accommodating spaces are arranged on the support frame 3, the battery assembly 4 is placed in the accommodating space, and the battery assembly 4 is arranged in an array to form a battery module; the battery assembly 4 includes a battery body 401, a locking plate 402 is rotatably arranged at the front end of the battery body 401, a locking motor is arranged on the locking plate 402, and a pull ring 403 is fixedly arranged at the front end of the battery body 401, and the staff can drag the battery body 401 or lift it to a high altitude through the pull ring 403; the locking plate 402 is driven to rotate by the locking motor, so that the locking plate 402 is overlapped on the blocking plate 10, so as to fix the battery body 401, and the blocking plate 10 is arranged on the support frame 3, and the locking plate 402 is overlapped on the blocking plate 10.

[0044] The working principle of the present invention is as follows: First, the battery body 401 is placed in the storage space and fixed. Specifically, the staff lifts the battery body 401 through the pull ring 403, and then places the tail end of the battery body 401 on the support plate 603 and the lifting support wheel 607, compresses the telescopic spring 605 and the auxiliary spring 610, and starts the shipping motor 612. The shipping 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 storage space. The battery body 401 drives the lifting support wheel 607 to continue rolling until the moving block 602 moves to the tail end of the storage space. At this time, the shipping motor 612 is stopped, and the battery body 401 has been placed in place. Then, the locking plate 402 is driven to rotate by controlling the locking motor so that the locking plate 402 can overlap the blocking plate 10 to fix the battery body 401.

[0045] Secondly, turn on the air supply component 2, and cooperate with the ventilation component 7 to achieve targeted cooling and heat dissipation. Specifically, turn on the electric fan 204, suck the external airflow into the air inlet box 201, the airflow passes through the electric fan 204 and enters the air supply pipe 202, and then passes through the ventilation holes on the left turn plate 702 and the right turn plate 703 in the ventilation component 7 to enter the storage space, and after heat exchange with the battery body 401, the airflow is output from the air outlet grille 106 on the box door 102, completing the heat exchange and cooling of the battery body 401. The flow direction of the heat exchange airflow is: air inlet grille 205-air inlet box 201-air supply pipe 202-rear end of the support frame 3-ventilation holes on the ventilation component 7-storage space of the support frame 3-front end of the support frame 3-box door 102-air outlet grille 106.

[0046] Finally, the ventilation volume of each battery body 401 is adjusted according to the temperature sensor on the battery body 401. Specifically, the battery temperature is divided into a normal range and a high temperature range, and the expansion and contraction volume of the output end of the micro-expansion cylinder 705 is controlled according to the temperature change of the battery body 401 detected by the temperature sensor.

[0047] When the temperature sensor detects that the temperature of the current battery body 401 is at the highest value in the high temperature range, the output end of the micro telescopic cylinder 705 is controlled to maintain the maximum extension, that is, Figure 8 , ensuring that the airflow 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 is reduced, the output end of the micro telescopic cylinder 705 is controlled to retract, driving the movable plate 704 to translate along the left turning plate 702, blocking the ventilation hole, reducing the air flow, and avoiding 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 a low temperature state, and it is necessary to stop ventilation and heat exchange for insulation, and control the output end of the micro telescopic cylinder 705 to retract until the movable plate 704 is driven to The ventilation holes are completely blocked, at which time, heat exchange stops and the battery body 401 is kept warm; when the temperature sensor detects that the current temperature drop of the battery body 401 exceeds the highest value in the high temperature range, it means that the battery body 401 can no longer effectively cool down and exchange heat by relying solely on the airflow through the ventilation holes. At this time, the output end of the micro-telescopic cylinder 705 is at its longest extension, and the left turn plate 702 and the right turn plate 703 are controlled to rotate clockwise at the same time through the power structure, and the moving plate 704 rotates with the left turn plate 702, so that the left turn plate 702 and the right turn plate 703 rotate to a state parallel to the horizontal column, opening the air inlet end of the accommodating space, so that the airflow can fully enter the accommodating space to exchange heat with the battery body 401 and quickly cool down.

[0048] Based on the technical solution of the above-mentioned embodiment one, the temperature difference between the battery bodies 401 in two adjacent accommodating spaces is relatively large, that is, when any one of the two cools down or heats up more, it is impossible to quickly exchange heat or heat up in a short period of time, resulting in a slow temperature recovery speed of the battery body 401; in addition, when bulging or leakage occurs on the battery body 401, it cannot be identified and distinguished in time, resulting in a safety hazard of the battery module during use; and thus embodiment two is proposed to solve the above-mentioned technical problems.

[0049] Embodiment 2: In two adjacent storage spaces, when the two battery bodies 401 are both within the normal range and the high temperature range, but the temperature difference is large, the temperature of one battery body 401 is adjusted faster, and the temperature of the other battery body 401 cannot be adjusted quickly in a short time, resulting in a slower temperature recovery speed of the battery body 401.

[0050] In order to solve the above technical problems, when the temperature sensor recognizes that the temperature difference of the battery body 401 in two adjacent storage spaces is large, the closing component 5 on the side close to each other in the two storage spaces is controlled to open, so that the airflows of the two storage spaces are interconnected, specifically: the driving motor 505 is controlled to drive the long rack 507 to move through the active 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, and the closing plate 501 rotates to a state perpendicular to the horizontal column. At this time, the two storage spaces are in an interconnected state, the airflows are interconnected, and they compensate each other, thereby accelerating the heat exchange cooling or heating efficiency of the battery body 401.

[0051] When the temperature sensors on the battery bodies 401 in two adjacent storage spaces detect that there is a large temperature difference between the two and that the temperature of one side is slowly adjusted, the closed component 5 on the side close to each other in the two storage spaces is controlled to open, so that the airflows of the two storage spaces are interconnected, thereby allowing the temperatures in the two spaces to compensate for each other, thereby accelerating the heating or cooling efficiency of the battery body 401 and ensuring the temperature recovery efficiency of the battery body 401.

[0052] During the long-term charging and discharging process of the battery body 401, the battery body 401 may swell or leak due to various factors. The existing technology cannot promptly assist the staff to identify and screen them out, resulting in safety hazards in the battery module composed of the battery body 401 during use.

[0053] During the process of opening the above-mentioned closure assembly 5, the closure plate 501 rotates, driving the telescopic plate 502 to rotate. During the rotation process, the end of the telescopic plate 502 can contact the side of the battery body 401, causing the reset spring to be compressed. The compression of the reset spring can be used to determine whether the current battery body 401 has a bulging phenomenon. Specifically, when the reset spring changes in compression in a consistent manner 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 of the reset spring changes inconsistently, and the compression of some reset springs is greater than that of the remaining reset springs, it means that the current battery body 401 has a bulging phenomenon and it should be screened out.

[0054] The screening process is as follows: first, the control center sends out an alarm to alert the staff; secondly, the locking motor is controlled to drive the locking plate 402 to rotate, so that the locking plate 402 moves away from the blocking plate 10, thereby releasing the fixation of the battery body 401; then, the shipping motor 612 is controlled to drive the screw 601 to rotate, thereby driving the battery body 401 to move a certain distance outside the accommodating space through the moving block 602, so that the bulging 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 pulls out the bulging battery body 401.

[0055] The change in the compression of the telescopic spring 605 and the auxiliary spring 610 is used to determine whether the current battery body 401 is leaking. 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 remains consistent. The control center records the compression at this time. When the compression of the telescopic spring 605 and the auxiliary spring 610 decreases as a whole or partially, it means that the battery body 401 is leaking, resulting in a reduction in the weight of the battery body 401, thereby reducing the compression of the telescopic spring 605 and the auxiliary spring 610 as a whole or causing a partial reduction in compression due to weight bias. At this time, the leaking battery body 401 needs to be screened out. Screening is performed through the above screening process.

[0056] By real-time detecting the change in compression of the reset spring as the telescopic plate 502 rotates with the closing plate 501, it is determined whether the current battery body 401 has a bulging phenomenon; by real-time detecting the change in compression of the telescopic spring 605 and the auxiliary spring 610, it is determined whether the current battery body 401 has a leakage, thereby controlling the moving block 602 to push the battery body 401 out of the accommodating space, so that the bulging or leaking battery body 401 can be quickly screened out by the staff, thereby reducing the safety hazards of the battery module during use.

[0057] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
