Description

Technical Field

[0001] This invention relates to the field of battery pack technology, specifically to an energy storage battery pack with a uniform temperature cooling system. Background Technology

[0002] In practical power storage operations, temperature control of storage batteries is particularly important. In traditional battery packs with air-cooled structures, cooling airflow enters from the air inlet at the front of the battery box, sequentially and parallelly washing the walls of each cell, and then flows out from the air outlet at the rear of the box. During the movement of the cold airflow, it is continuously heated by the working cells, causing the convective heat transfer effect of the battery pack to decrease rapidly. Current energy storage battery packs with uniform temperature cooling systems are not easy to control the uniform temperature cooling of the cells, resulting in poor heat dissipation uniformity and inadequate battery protection. Air conditioning cooling produces a large amount of condensate, which usually requires an aluminum protective shell for protection while ensuring heat dissipation. However, aluminum protective shells that have been submerged for a long time are prone to pinhole leaks, making it difficult to use exhaust gas for leak prevention. In addition, the terminals of traditional battery packs are usually directly welded with copper busbars. When the battery swells, the terminals may detach, causing potential hazards such as loose connections. To ensure the stability of the battery pack during transportation and other operations, the cells are usually fixed. Once a cell swells, it can easily cause crush damage to surrounding cells, expanding safety hazards, and it is not easy to automatically control and compensate for the swell distance.

[0003] Therefore, we propose an energy storage battery pack with a uniform temperature cooling system. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention employs a uniform temperature cooling component to achieve uniform air intake cooling. By utilizing the fact that the diameter of the central region of each row of exhaust holes is larger than that of the two side regions, the uniformity of heat dissipation and cooling is improved. The invention also employs a cell protection component, which utilizes internally slidingly mounted cell terminal posts to enhance cell safety. In the event of localized cell bulging, the slidingly mounted cell terminal posts of this structure can slide and adapt within the slot, ensuring stable power connection. This prevents the traditional method of connecting cell terminals with welded copper busbars, which can easily cause the welded copper busbars to detach if a localized cell bulges, thus avoiding the potential for loose connections.

[0017] The use of pressure detection components, in conjunction with exhaust gas pressurization components, enables automatic detection of the sealing performance of the battery cell protective casing. This prevents issues such as pinholes caused by prolonged immersion in condensate, which could lead to direct leakage of condensate into the battery cell and cause short circuits or other serious safety accidents. The system can automatically utilize exhaust gas to provide air pressure to the battery cell protective casing, creating internal air pressure to prevent condensate infiltration, thus ensuring greater safety and safety.

[0018] The use of cell spacers in conjunction with bulging detection components does not affect the stability of the two rows of cells during transportation and installation, ensuring that the two rows of cells will not shake randomly, causing additional wear and the risk of desoldering, thus improving cell safety. At the same time, when the two rows of cells bulge, it can be automatically detected and the spacer slider can be controlled to retract, allowing the cells to have space to expand. This avoids the problem of surrounding cells being directly squeezed when a traditional tightly fitted cell bulges in a local area, which can also cause short circuits and other problems, further increasing safety hazards and improving the explosion-proof effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 11 As shown:

[0033] This invention provides a technical solution: an energy storage battery pack with a uniform temperature cooling system, including a battery mounting part 1, a uniform temperature cooling component 2 mounted on the battery mounting part 1 for ventilation cooling; a cell protection part 3 mounted on the battery mounting part 1 for preventing condensate corrosion; a tail gas pressurizing component 4 mounted on the battery mounting part 1; a pressure detection component 5 mounted on the cell protection part 3; the tail gas pressurizing component 4 for pressurizing the cell protection part 3 to prevent leakage; a bulging detection component 6 mounted inside the cell protection part 3; and cell spacers 7 mounted on the cell protection part 3 for compensating for bulging distance; the battery mounting part 1 includes a battery casing 101 and a condensate drain hole 1012, with the condensate drain hole 1012 opened at the bottom of the battery casing 101; a drain hose is connected to the condensate drain hole 1012.

[0034] The battery mounting section 1 further includes: an air conditioning docking cover 1011 and an exhaust pipe 102. The air conditioning docking cover 1011 is fixedly installed at the front end of the battery housing 101, and the air conditioning docking cover 1011 is connected to the air conditioning outlet pipe through a flexible hose. The front end of the battery housing 101 is provided with two through slots. The exhaust pipe 102 is fixedly installed at the rear end of the battery housing 101, and the exhaust pipe 102 passes through the battery cabinet. The temperature equalization cooling component 2 includes: a cooling pipe 201, an air inlet 2011, and an exhaust port 202. Two cooling pipes 2011 are fixedly installed inside the battery housing 101. 01; Two cooling pipes 201 are respectively provided with air inlets 2011 on their sides, and the air inlets 2011 are connected to the air conditioner docking cover 1011; Two exhaust holes 202 are respectively provided at the bottom of the two cooling pipes 201, and the diameter of the middle area of ​​each row of exhaust holes 202 is larger than the diameter of the side areas; the exhaust holes 202 are used for air jet ventilation; The cell protection part 3 includes: a cell protection shell 301, a cell 3011 and a cell terminal post 3012, the cell protection shell 301 is fixedly installed inside the battery shell 101; the bottom of the cell protection shell 301 is provided with a... The casing 301 contains a groove for the flow of condensate; two rows of battery cells 3011 are arranged inside the battery cell protective shell 301; two rows of battery cell terminal posts 3012 are fixedly installed at the ends of the two rows of battery cells 3011, and the two rows of battery cell terminal posts 3012 correspond to the positive and negative terminals of the battery cells 3011 respectively; the battery cell protective shell 301 is a closed shell structure, and the uniform temperature cooling component 2 can achieve uniform temperature air intake cooling. The diameter of the central area of ​​each row of exhaust holes 202 is larger than that of the side areas. The diameter can be set according to requirements. Smaller exhaust holes 202 can reduce the exhaust air force and reduce the air pressure. Low cooling airflow intensity; for areas of the battery pack prone to high temperatures, such as the middle cell 3011, which has poor heat dissipation, the inner diameter can be appropriately increased to distribute more cold air and enhance the cooling airflow effect, thereby improving the uniformity of heat dissipation and cooling of the battery pack and ensuring the performance of cell 3011. At the same time, the cell 3011 is installed inside the cell protective shell 301. The cell protective shell 301 is made of aluminum, which can ensure heat dissipation while protecting the cell 3011 and preventing condensate from directly soaking the cell 3011, thus improving the safety of this structure.

[0035] The cell protection unit 3 also includes: a charging pipe 302, a contact post 303, a bonding spring 3013, a slot block 304, and a contact piece 3041. The charging pipe 302 is fixedly installed on the side of the cell protection shell 301, and a valve is provided on the charging pipe 302. The charging pipe 302 is used to connect an external air pump to pressurize the inside of the cell protection shell 301. Four contact posts 303 are fixedly installed on the cell protection shell 301. Four slot blocks 304 are fixedly installed on the inner top of the cell protection shell 301, and four... A contact piece 3041 is fixedly installed on the inner side of the slot block 304, and the four contact pieces 3041 are fixedly connected to the four contact posts 303 respectively; the contact posts 303 are insulated from the battery casing 101; the contact posts 303 are used for external cables; two rows of battery cell terminal posts 3012 are slidably connected to the inner side of the four slot blocks 304 respectively, and a contact spring 3013 is fixedly installed on the two rows of battery cell terminal posts 3012 respectively; the four rows of contact springs 3013 elastically contact the four contact pieces 304 respectively. 1; The four terminals 303 are coated with a rubber coating; The cell protection unit 3 utilizes the internally slidingly mounted cell terminal post 3012 to improve the safety of the cell 3011. When local swelling occurs in the cell 3011, the slidingly mounted cell terminal post 3012 can slide and adapt inside the slot block 304, ensuring stable power connection and preventing the traditional method of connecting cell terminals with welded copper busbars from easily detaching when local cell swelling occurs. To avoid potential loose connections, the structure is more reasonable and ensures the sealing and protection of the battery cell 3011. The four terminals 303 can be connected to external cables to connect the two rows of battery cells 3011. When the battery cell 3011 bulges, the expanded battery cell 3011 will shift. During this process, the battery cell terminal post 3012 will drive the bonding spring 3013 to slide and adapt within the slot 304. The bonding spring 3013 will continuously bond with the connecting piece 3041 to prevent loose connections.

[0036] The exhaust gas pressurization component 4 includes: a return pipe 401, a solenoid valve 402, and an exhaust housing 403. The end of the return pipe 401 is fixedly installed on the exhaust gas exhaust pipe 102; the solenoid valve 402 is fixedly installed on the return pipe 401; the return pipe 401 passes through the battery housing 101; the exhaust housing 403 is fixedly installed on the return pipe 401 and is fixedly installed inside the battery housing 101; the end of the exhaust housing 403 is fixedly installed on the side of the battery cell protection housing 301; the battery cell protection housing 301 is connected to the exhaust housing 403; the exhaust gas pressurization component 4 also includes: an exhaust fan 404, and the exhaust housing 403... An exhaust fan 404 is fixedly mounted inside the battery cell protective shell 301 via a bracket. The exhaust fan 404 consists of a motor and an impeller. The exhaust fan 404 is used to inflate the battery cell protective shell 301. The pressure detection component 5 includes a pressure piston shell 501, a micro switch 502, a piston 503, and a buzzer 504. The pressure piston shell 501 is fixedly mounted on the battery cell protective shell 301. The micro switch 502 is fixedly mounted inside the pressure piston shell 501. The piston 503 is slidably mounted on the pressure piston shell 501, and a spring is connected to the tail of the piston 503. The spring at the tail of the piston 503 is located within the pressure piston shell 501. 01 Internally; Piston 503 presses against microswitch 502; Buzzer 504 is fixedly installed at the tail of pressure piston housing 501; Microswitch 502 is electrically connected to solenoid valve 402, exhaust fan 404 and buzzer 504. Using pressure detection component 5, it can cooperate with exhaust gas pressurization component 4 to automatically detect the sealing performance of battery cell protective housing 301, avoiding sand holes caused by prolonged immersion in condensate, which could lead to direct leakage of condensate dripping onto battery cell 3011 and causing short circuits or other major safety accidents. This improves the protection effect of battery cell 3011 and also enables automatic utilization of exhaust gas. The cell protection shell 301 is protected by air pressure supply. This creates air pressure inside the cell protection shell 301, which can prevent the infiltration of condensate and is safer and more reasonable. When the cell protection shell 301 leaks, the air pressure inside the cell protection shell 301 decreases. The air pressure no longer pushes the piston 503 to move inside the pressure piston shell 501 and presses the micro switch 502. This can control the buzzer 504 to sound an alarm. At this time, the solenoid valve 402 opens and the exhaust fan 404 starts to absorb exhaust gas from the exhaust pipe 102, preventing the internal temperature of the energy storage cabinet from getting too high. The exhaust gas is then directly discharged into the cell protection shell 301 for air pressure protection.

[0037] In Example 2, based on Example 1, the bulging detection component 6 includes: a suspension rubber sheet 601 and a contact spring 602. Two rows of suspension rubber sheets 601 are fixedly installed inside the battery cell protective shell 301, with the two rows of suspension rubber sheets 601 located between two rows of battery cells 3011. Two contact springs 602 are fixedly installed at the bottom of each of the two rows of suspension rubber sheets 601, with a gap between the ends of the two contact springs 602. The sides of the two contact springs 602 are respectively pasted to the sides of two adjacent battery cells 3011. The battery cell spacer 7 includes: a spacer slider 701 and an electromagnet. 702 and V-shaped spring 703; four rows of spacer sliders 701 are slidably inserted into the cell protective shell 301, and the four rows of spacer sliders 701 are respectively inserted between two rows of cells 3011; four rows of electromagnets 702 are fixedly installed on the cell protective shell 301, and the four rows of electromagnets 702 are respectively aligned with the spacer sliders 701; V-shaped springs 703 are fixedly installed between the four rows of spacer sliders 701 and the electromagnets 702; the electromagnets 702 are used to magnetically attract the spacer sliders 701; the two rows of connecting springs 602, the buzzer 504 and the four rows of electromagnets 702 are connected in series with the battery power supply, and cell spacers are used. 7. In conjunction with the bulging detection component 6, it does not affect the stability of the two rows of battery cells 3011 during transportation and installation, ensuring that the two rows of battery cells 3011 will not shake randomly, causing additional wear and the risk of desoldering, thus improving the safety of the battery cells 3011. Simultaneously, when bulging occurs in the two rows of battery cells 3011, it can automatically detect and control the retraction of the spacing slider 701, allowing the battery cells 3011 space to expand. This avoids the direct compression of surrounding battery cells 3011 when local bulging occurs in traditional tightly fitted battery cells 3011, which can also cause short circuits and other problems, further increasing safety hazards and improving the explosion-proof effect. Simultaneously, with the sliding cell terminal post 3012, loose connections are avoided, making the structure more reasonable. Once a local cell 3011 expands, the contact spring 602 on its side will be squeezed. At this time, two adjacent contact springs 602 will move closer until their ends are in contact, and the circuit will be connected. At this time, the buzzer 504 will also sound to indicate that the four rows of electromagnets 702 are energized, so that the magnetically attracted spacer slider 701 can be realized. The spacer slider 701 can then retract and no longer insert the cell 3011. At this time, the gap between the two rows of cells 3011 can provide expansion distance for the expanded cell 3011.

[0038] The working principle of this embodiment is as follows: First, the battery casing 101 is placed on a bracket inside the energy storage cabinet. The exhaust pipe 102 can pass through the battery cabinet to discharge the exhaust gas. The air conditioner docking cover 1011 is connected to the air conditioner outlet pipe through a flexible hose. When the air conditioner exhausts air to cool the battery cell 3011, the air pressure first passes through the air inlet 2011 and is discharged from the exhaust port 202 for cooling. The large diameter of the middle part of the exhaust port 202 allows more airflow to be discharged. During the use of this structure, when temperature regulation and other operations occur, condensate can be discharged from the condensate discharge port 1012. The battery cell protective casing 301... This design serves a protective function, preventing condensate from directly soaking the battery cell 3011. Four terminals 303 can be connected to external cables to connect to the two rows of battery cells 3011. When a battery cell 3011 bulges, the expanding cell shifts, causing the battery cell terminal post 3012 to slide and adapt within the slot 304 along with the contact spring 3013. During this process, the contact spring 3013 continuously engages with the contact plate 3041 to prevent loose connections. An external air pump connected to the charging pipe 302 pressurizes the inside of the battery cell protective shell 301, and then the valve on the charging pipe 302 is tightened to close it. Subsequent... When the battery cell protective shell 301 leaks, the internal air pressure of the battery cell protective shell 301 decreases. The air pressure no longer pushes the piston 503 to move inside the pressure piston shell 501 and press against the micro switch 502. Under the compression of the spring at the tail of the piston 503, it moves outward. At this time, when the micro switch 502 is no longer pressed, it can control the buzzer 504 to sound as a warning. At this time, the solenoid valve 402 opens, and the exhaust fan 404 starts, absorbing exhaust gas from the exhaust pipe 102 and directly discharging it into the battery cell protective shell 301 for air pressure protection. Once a local battery cell 3011 expands, the side of its contact... When the electro-electromagnetic contact 602 is compressed, two adjacent contact 602s move closer together until their ends touch, and the circuit is connected. At this time, the buzzer 504 will also sound to indicate this, and at the same time, it controls the four rows of electromagnets 702 to be energized, so that the magnetically attracted spacer slider 701 can be achieved. The spacer slider 701 can then retract and no longer insert the battery cell 3011. At this time, the gap between the two rows of battery cells 3011 can provide expansion distance for the expanding battery cell 3011, reducing the squeezing damage to the surrounding normal battery cells 3011. The structure is more reasonable and does not affect the stability of the two rows of battery cells 3011 in the normal state.
