[0002] The high-dynamics energy storage cell is usually installed in the inside of the battery shell by adhesive fixing. The adhesive fixing operation is relatively simple, but it also has many shortcomings. On the one hand, the adhesive fixing makes it difficult to disassemble and replace the cell. If the adhesive is not uniformly coated, it may cause local thermal resistance to increase, thereby affecting the heat dissipation effect, especially in the case of thick adhesive layer, the heat conduction performance may decrease significantly. Moreover, when the cell is air-cooled, the air cooling can only be performed from the surface of the cell, so that the heat dissipation effect is poor. On the other hand, in high-temperature or low-temperature environment, the adhesive may age, crack or decrease in adhesion, thereby affecting its heat conduction performance and long-term reliability, making the cell installation not stable enough, and the cell may become loose. At the same time, the anti-vibration performance is poor, which affects the safe use of the cell. SUMMARY

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0049] This invention provides a technical solution:
[0050] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a high-dynamic energy storage cell with thermal management and safety architecture is disclosed. The core design concept of this high-dynamic energy storage cell differs significantly from that of power cells in consumer electronics or electric vehicles. High-dynamic energy storage cells are specifically designed and manufactured for large-scale energy storage, and are relatively large, often with a square shell structure. Specifically, the high-dynamic energy storage cell disclosed in this invention includes: a cell body 1, a first safety protection component, a second safety protection component, and a thermal management component. The cell body 1 has a positive and a negative electrode, and an electrolyte is injected inside, forming the basic structure of the cell body. A heat dissipation channel 11 is provided on the cell body 1, allowing heat to be dissipated from inside the shell of the cell body 1. That is, when the cell body 1 is subjected to air cooling, air can pass through the heat dissipation channel 11 to carry away heat. Through this combined internal and external heat dissipation method, the cell body can effectively dissipate heat. The electrolyte inside cell 1 is cooled more efficiently. When cell 1 is installed in the first safety protection component, the first safety protection component protects the cell 1 and ensures its safe use. The second safety protection component is installed on cell 1. When cell 1 is not installed in the first safety protection component, the second safety protection component protects cell 1. The second safety protection component can protect cell 1 from external impacts. When cell 1 is installed in the first safety protection component, it is fixed by the second safety protection component to achieve stable installation of cell 1. The thermal management component is installed on the first safety protection component to dissipate heat from cell 1. When dissipating heat from cell 1, it can achieve simultaneous internal and external heat dissipation, further improving the heat dissipation effect of cell 1.
[0051] like Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 12 As shown, the first safety protection component for the battery cell includes a battery casing 2 and a closed casing plate 3. The battery casing 2 is used to install the battery cell body 1 and protect the battery cell body 1. An internal positioning strip 24 is welded and fixed inside the battery casing 2. An interlocking cavity 25 is opened on the internal positioning strip 24. When the battery cell body 1 is installed inside the battery casing 2, the internal positioning strip 24 is located around the battery cell body 1 and contacts the battery cell body 1. The internal positioning strip 24 positions the battery cell body 1 so that its installation position is accurate.
[0052] The sealing plate 3 is installed on the battery case 2 to seal the battery case 2. That is, the sealing plate 3 covers the upper port of the battery case 2 and seals the upper port of the battery case 2, which can provide better protection for the battery cell body 1.
[0053] A locking plate 36 is movably mounted on the closed shell plate 3, and a support interlocking rod 363 is fixedly installed on the locking plate 36. Specifically, a heat dissipation hole 34 is opened on the closed shell plate 3, and the locking plate 36 is inserted into the heat dissipation hole 34. A support channel 35 is opened in the heat dissipation hole 34, and the support interlocking rod 363 is inserted into the support channel 35. Through the cooperation of the support channel 35 and the support interlocking rod 363, the locking plate 36 can also be supported, allowing it to move in the heat dissipation hole 34 without separating from it. A matching support column 21 is welded and fixed on the periphery of the battery shell 2. An interlocking channel 22 is opened on the matching support column 21. When the support interlocking rod 363 is inserted into the interlocking channel 22, a fixed connection is achieved between the closed shell plate 3 and the battery shell 2.
[0054] Additionally, when the support interlocking rod 363 is inserted into the interlocking channel 22, in order to fix the locking plate 36 and ensure the firmness of the connection between the closed shell plate 3 and the battery shell 2, a mating protrusion ring 32 is integrally formed on the upper end of the closed shell plate 3. A mating groove 33 is formed on the mating protrusion ring 32. Elastic support bars 361 are symmetrically welded and fixed on the locking plate 36. An inclined locking block 362 is integrally formed on the end of the elastic support bar 361 away from the locking plate 36. The surface of the inclined locking block 362 is smooth and burr-free. The support interlocking rod 363 is inserted into... During the interlocking process of the interlocking channel 22, the elastic support bar 361 will enter the mating groove 33. When it enters, the inclined locking block 362 will be squeezed by the groove of the mating groove 33, which will cause the elastic support bar 361 to deform. After the inclined locking block 362 passes the mating groove 33, the elastic support bar 361 will return to its original shape. The inclined locking block 362 will be stuck on the outer end face of the mating protrusion ring 32, which can fix the locking plate 36, thereby ensuring a stable connection between the closed shell plate 3 and the battery shell 2. The lower end of the closed shell plate 3 is also welded and fixed with a pressure strip plate 37.
[0055] like Figure 4 As shown, an air inlet channel 12 is also provided on the lower side of the heat dissipation channel 11, and the air inlet channel 12 is connected to the heat dissipation channel 11 on the upper side. A matching support strip 13 is symmetrically welded and fixed on the side of the cell body 1. A storage cavity 14 is provided on the matching support strip 13. A connecting through hole 15 is provided at the bottom of the storage cavity 14. The connecting through hole 15 passes through the matching support strip 13. In addition, an insertion pressure groove 16 is provided at the upper end of the cell body 1. When the cell body 1 is installed inside the battery case 2 and the sealing shell plate 3 covers the upper port of the battery case 2, the lower pressure strip 37 is inserted into the insertion pressure groove 16 to press down and fix the cell body 1.
[0056] like Figure 1 , Figure 8 and Figure 11 As shown, the second safety protection component for the battery cell includes a protective opening frame 4 and a movable support strip 44. The protective opening frame 4 surrounds the battery cell body 1 from all sides. A connecting air duct 41 is welded and fixed to the lower end of the protective opening frame 4. One end of the connecting air duct 41 is inserted into the air inlet channel 12. A sealing strip 42 is integrally formed on the upper end of the protective opening frame 4. The sealing strip 42 covers and seals the port of the heat dissipation channel 11. The movable support strip 44 is installed on the battery cell body 1 and is movably connected to the protective opening frame 4. Specifically, a connecting support rod 45 is welded and fixed to the movable support strip 44. The connecting support rod 45 is inserted into the connecting through hole 15. A movable connecting rod 43 is hinged to the movable support strip 44. The other end of the movable connecting rod 43 is hinged to the protective opening frame 4.
[0057] When the battery cell body 1 is not installed in the battery casing 2, the protective opening frame 4 cooperates with the battery cell body 1 to protect it from the periphery. That is, at this time, the lower end and both ends of the protective opening frame 4 are attached to the battery cell body 1. The overall volume of the battery cell body 1 is also relatively small, which facilitates the transportation and storage of the battery cell body 1. In addition, at this time, the movable connecting rod 43, the movable support bar 44, and the connecting support rod 45 are all located inside the protective opening frame 4. The three of them cooperate with the protective opening frame 4 to provide good protection for the battery cell body 1 from the periphery, ensuring the safety of the battery cell body 1.
[0058] When the protective mouth-shaped frame 4 moves, the movable support bar 44 moves along the connecting through hole 15 via the movable connecting rod 43.
[0059] When the locking plate 36 moves, it drives the second safety protection component of the battery cell to move, thus fixing the battery cell body 1. Specifically, a mating interlocking strip 46 is welded and fixed on the connecting rod 45 of the movable support bar 44. The mating interlocking strip 46 is inserted into the storage cavity 14. When the closed shell plate 3 is installed on the battery shell 2, the lower end of the locking plate 36 is inserted between the protective opening frame 4 and the battery cell body 1. When the locking plate 36 moves, it will come into contact with the protective opening frame 4, thereby pushing the protective opening frame 4 to move. When the protective opening frame 4 moves, the movable connecting rod 43 drives the movable support bar 44 to move in the direction of the mating support bar 13. This allows the mating interlocking strip 46 to move out of the storage cavity 14 and into the interlocking cavity 25. Thus, the battery cell body 1 can be fixed by the cooperation of the mating interlocking strip 46 and the interlocking cavity 25.
[0060] In addition, in order to ensure the stability of the protective frame 4 when protecting the battery cell body 1, a first spring 47 is sleeved on the connecting support rod 45. The two ends of the first spring 47 are welded and fixed to the mating support bar 13 and the movable support bar 44, respectively.
[0061] like Figure 3 , Figure 5 , Figure 9 , Figure 10 and Figure 13 As shown, the battery cell thermal management assembly includes: a cooling fan 5, a duct 51, a movable air duct 6, and a movable frame 7. The cooling fan 5 is fixedly mounted on the battery casing 2 by bolts. The duct 51 is fixedly mounted inside the battery casing 2 by bolts. A delivery air duct 52 is welded and fixed to the duct 51. A lower insertion channel 23 is provided on the battery casing 2. The delivery air duct 52 is inserted into the lower insertion channel 23 and partially protrudes out of the outer side of the battery casing 2 to connect with the cooling fan 5. The cooling fan 5 delivers airflow to the duct 51.
[0062] An insert strip 31 is integrally formed on the closed shell plate 3. When the closed shell plate 3 is installed on the battery shell 2, the insert strip 31 is inserted into the lower insertion channel 23 and is located on the upper side of the conveying air duct 52 to close the lower insertion channel 23.
[0063] The movable air duct 6 is movably installed on the orifice-shaped air duct 51. Specifically, a supporting air duct 53 is welded and fixed to the orifice-shaped air duct 51. One end of the movable air duct 6 is inserted into the supporting air duct 53. A supporting block 55 is welded and fixed to the orifice-shaped air duct 51 on the upper side of the movable air duct 6. A supporting through hole 56 is opened on the supporting block 55. A T-shaped plate 61 is welded and fixed to the movable air duct 6. A supporting movable rod 62 is welded and fixed to the T-shaped plate 61. The supporting movable rod 62 is inserted into the supporting through hole 56. A second spring 63 is sleeved on the supporting movable rod 62. The two ends of the second spring 63 are welded and fixed to the T-shaped plate 61 and the supporting block 55, respectively.
[0064] The movable frame 7 is also movably installed on the mouth-shaped air duct 51.
[0065] When the protective vent frame 4 is moved, the other end of the connecting air duct 41 is inserted into the movable air duct 6, and the movable air duct 6 is in contact with the protective vent frame 4, which drives the movable air duct 6 to move. In this way, the movable air duct 6 can be connected to the air inlet channel 12 through the connecting air duct 41, thereby realizing the connection between the movable air duct 6 and the heat dissipation channel 11.
[0066] An exhaust duct 54 is provided on the duct 51. The exhaust duct 54 is sealed by the movable frame 7 to prevent external dust from entering the duct 51 through the exhaust duct 54. Specifically, a guide plate 57 is integrally formed on the upper end of the support block 55. A limiting top plate 58 is welded and fixed on the upper end of the guide plate 57. A guide channel 71 is provided on the movable frame 7, and the guide plate 57 is inserted into the guide channel 71. The movable frame 7 is limited by the cooperation of the guide plate 57 and the guide channel 71. The limiting top plate 58 is located on the upper side of the movable frame 7. When the movable frame 7 moves, the limiting top plate 58 can limit it to prevent the movable frame 7 from separating from the guide plate 57. A channel sealing plate 73 is integrally formed on the lower side of the movable frame 7 to cover and seal the exhaust duct 54.
[0067] A push plate 64 is welded and fixed to one end of the support rod 62 away from the T-shaped plate 61. An inclined plate 72 is welded and fixed to the movable plate frame 7. The surface of the inclined plate 72 is smooth and burr-free, and the inclined plate 72 is located on the upper side of the push plate 64. When the movable air duct 6 moves, the push plate 64 will push the inclined plate 72 to move upward, thereby driving the channel sealing plate 73 to move upward, so that the exhaust channel 54 is in the open state. In this way, the air can be discharged from the exhaust channel 54 and blown to the surface of the battery cell body 1. At this time, the upper end surface of the movable plate frame 7 is in contact with the lower end surface of the limiting top plate 58.
[0068] When installing the battery cell body 1, it is placed in the battery case 2, and the battery cell body 1 is positioned by the built-in positioning strip 24 in the battery case 2 to ensure the accuracy of its installation position.
[0069] After the battery cell body 1 is placed, the sealing shell plate 3 can be placed over the port of the battery case 2, so that the locking plate 36 can be inserted between the protective port frame 4 and the battery cell body 1. After the sealing shell plate 3 is placed, the lower pressure plate 37 is also inserted into the insertion groove 16 and contacts the inner wall and bottom surface of the insertion groove 16. In this way, the lower pressure plate 37 and the insertion groove 16 can press down and fix the battery cell body 1. Then the locking plate 36 can be moved in sequence. When the locking plate 36 moves, the inclined locking block 362 will contact the groove wall of the mating groove 33. Under the pressure of the groove wall of the mating groove 33, the elastic support bar 361 will deform, and the inclined locking block 362 will be inserted into the mating groove 33.
[0070] The inclined locking block 362 moves along the mating groove 33 until it moves out of the mating groove 33. At this time, the inclined locking block 362 is no longer restricted, which in turn causes the elastic support bar 361 to be unrestricted. The elastic support bar 361 can then recover its deformation. As the elastic support bar 361 recovers its deformation, the inclined locking block 362 will be locked on the outer end face of the mating protrusion ring 32, thereby fixing the locking plate 36. During the movement of the locking plate 36, the support interlocking rod 363 on the locking plate 36 will be inserted into the interlocking channel 22. This achieves a fixed connection between the closed shell plate 3 and the battery shell 2, and the fixing of the locking plate 36 ensures the stability of the fixed connection between the closed shell plate 3 and the battery shell 2.
[0071] In addition, when the locking plate 36 moves, it will come into contact with the protective opening frame 4. Under the action of the locking plate 36, the protective opening frame 4 will be pushed to move away from the battery cell body 1. As the protective opening frame 4 moves, under the action of the movable connecting rod 43, the movable bearing strip 44 will be driven to move towards the built-in positioning strip 24, thereby driving the interlocking strip 46 receiving cavity 14 to be inserted into the interlocking cavity 25, fixing the battery cell body 1. With the fixing action of the closed shell plate 3, the battery cell body 1 can be firmly fixed inside the battery shell 2, ensuring its installation stability and firmness, and thus ensuring its safety in use.
[0072] Furthermore, when the protective nozzle frame 4 moves away from the battery cell body 1, it will cause the end of the connecting duct 41 near the movable air duct 6 to be inserted into the movable air duct 6, achieving a sealed connection between the movable air duct 6 and the connecting duct 41, thereby connecting the movable air duct 6 and the heat dissipation channel 11. The protective nozzle frame 4 is in contact with the movable air duct 6, thus pushing the movable air duct 6 to move under the action of the protective nozzle frame 4. As the movable air duct 6 moves, the push plate 64 will push the inclined plate 72 upward, thereby causing the channel sealing plate 73 to move upward. This allows the exhaust duct 54 to be open, so that when the cooling fan 5 is cooling the battery cell 1, the airflow can be discharged from the exhaust duct 54. This allows the airflow to directly act on the surface of the battery cell 1. At the same time, the airflow can also enter the air intake duct 12 through the connection between the movable air duct 6 and the connecting air pipe 41, and finally be discharged from the heat dissipation duct 11. This way, the heat generated by the battery cell 1 can be carried away from the inside of the battery cell 1 shell. By combining the inside and outside, the battery cell 1 is cooled by air, which greatly improves the heat dissipation efficiency of the battery cell 1.
[0073] When the battery cell body 1 is not installed inside the battery casing 2, it can be protected by the protective opening bracket 4 to prevent it from being hit by external forces. At this time, the sealing strip 42 covers the port of the heat dissipation channel 11, which can also prevent external dust from entering the heat dissipation channel 11 from the port of the heat dissipation channel 11 and affecting the heat dissipation effect of the battery cell body 1 in the later stage. When it is necessary to remove the battery cell body 1, the elastic support strip 361 on the locking plate 36 is squeezed so that the inclined locking block 362 is no longer stuck on the outer end face of the mating protrusion ring 32, and the locking plate 36 can be unlocked. Moving it can unlock the closed casing plate 3. At the same time, under the action of the first spring 47, the protective opening bracket 4 will also be driven to reset, realizing the complete unlocking of the battery cell body 1 and quickly disassembling it.
[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
