[0019] Example: Reference Figure 1-Figure 8The intelligent battery system for new energy vehicles includes a box body 1, in which a plurality of single cells 3 are placed, and also includes a power connection component, including a detection box 4 arranged on one side of an adjacent single cell 3, and a first slider 12 and a second slider 13 are respectively slidably installed on the top of the detection box 4, and a first connector 18 is elastically installed at one end of the first slider 12 and the second slider 13 away from each other, and an elastic rod 17 is fixedly installed at one end of the first slider 12 and the second slider 13 away from each other, and the first connector 18 is fixedly installed on the elastic rod 17, and the two first connectors 18 are used to connect the positive and negative electrodes of the adjacent single cells 3, and a fourth connector 21 is slidably installed on the inner wall of the box body 1, and a third connector 20 is fixedly installed on the first slider 12 near the fourth connector 21, and a first rack 22 is connected to one side of the third connector 20, and a second rack 23 is connected to the fourth connector 21, and a gear 24 is rotatably installed on the box body 1, and the gear 24 is respectively meshed with the first rack 22 and the second rack 23, and a protection component is also provided, including a cooling tube 27 (cooling tube 27) slidably installed in the detection box 4 A second spring 37 is connected between the cooling tube 27 and the bottom wall of the detection box 4, an air bag 36 is provided between the cooling tube 27 and the bottom wall of the detection box 4, and an evaporative liquid is provided in the air bag 36. When the air bag 36 expands due to heat, it pushes the cooling tube 27 to move upward. When the cooling tube 27 moves upward, the first slider 12 is away from the electrode of the single battery 3, and the second slider 13 on the single battery 3 connected thereto is separated from the electrode. The two first connectors 18 are elastically mounted with second connectors 19 at the ends away from each other. The protection component also includes a wedge fixedly mounted on the bottom wall of the first slider 12. A first pressing block 26 is fixedly mounted on the top wall of the wedge-shaped block 25, and the top end of the first pressing block 26 is slidably connected to the inclined surface of the wedge-shaped block 25. A piston tube 14 is fixedly mounted on the first slider 12, and a piston rod 15 is movably inserted on the piston tube 14, and the piston rod 15 is fixedly connected to the second slider 13 at one end away from the piston tube 14. A connecting pipe 16 is connected between every two piston tubes 14. A first clamp 38 is provided on the first slider 12, and a second clamp 39 matched with the first clamp 38 is provided on the second slider 13.

[0020] refer to Figure 1-Figure 8 A plurality of jacks 5 adapted to the size of the single battery 3 are provided on the bottom wall of the box body 1, a recycling box 2 is connected to the bottom wall of the box body 1, a slide groove 6 is provided on the inner wall of the box body 1, a separation plate 7 is slidably installed in the slide groove 6, and a first spring 11 is connected between the separation plate 7 and the bottom wall of the slide groove 6, a limiting component is provided between the separation plate 7 and the slide groove 6, and the limiting component includes a limiting groove 10 provided on the side wall of the slide groove 6, a connecting plate 8 is fixedly installed on the outer wall of one side of the separation plate 7, and a magnetic protrusion 9 is elastically installed on the side wall of the connecting plate 8, an adjusting groove 40 is jointly provided between the side wall of the detection box 4 and the side wall of the box body 1, a magnetic block that repels the magnetic protrusion 9 is provided at the end of the cooling tube 27, and the magnetic block is slidably installed in the adjusting groove 40.

[0021] The detection box 4 is pre-installed in the box body 1 , and one side of the detection box 4 is a heat-insulating surface, that is, one detection box 4 can detect the operating temperature of one single battery 3 .

[0022] When in use, the single battery 3 is installed in the insertion hole 5 at the bottom of the box body 1 from bottom to top (the box body 1 can also be inverted to perform the operation). During the insertion process, the single battery 3 will squeeze the corresponding separation plate 7 to slide along the slide groove 6, and stretch the first spring 11, and the connecting plate 8 and the magnetic protrusion 9 will slide along with the separation plate 7. When the magnetic protrusion 9 slides to a position aligned with the limiting groove 10, it is clamped into the limiting groove 10 under the action of the elastic force. It is worth noting that Figure 4 As shown, a baffle 44 is movably inserted at the bottom end of the connecting plate 8, wherein a return spring is provided at the sliding connection, and the end of the baffle 44 close to the slide groove 6 is an inclined surface, that is, during the sliding process of the connecting plate 8, the slide groove 6 will be used to squeeze the baffle 44 out to support the bottom end of the single battery 3, thereby ensuring the stability of the single battery 3.

[0023] The single cells 3 in the box 1 can be divided into two types, one is the two cells at the ends of the battery pack (hereinafter referred to as edge cells), and the other is the cell located in the middle part of the battery pack (hereinafter referred to as middle cell). According to the overheating of these two types of cells, two measures are taken respectively: When the middle battery overheats, Figure 6 and Figure 7 As shown, the airbag 36 in the corresponding detection box 4 expands, pushing the cooling tube 27 upward, and in the process of moving upward, it will drive the first pressing block 26 to squeeze the wedge block 25, so that the first slider 12 slides, as shown in FIG. Figure 5 As shown, the sliding direction is that the corresponding first connector 18 is away from one of the electrodes of the single battery 3, such as Figure 7 As shown, when the first slider 12 slides, the air at the end of one of the piston tubes 14 will enter the front end of the other piston tube 14 connected thereto, thereby driving the piston rod 15 of the other piston tube 14 to move inward, thereby driving the corresponding other first connector 18 away from the other electrode of the battery, so that both electrodes of the overheated battery are separated from the first connector 18, and at the same time, the two first connectors 18 approach each other, thereby driving the two second connectors 19 to fully contact, so as to complete the normal series connection by skipping the overheated battery.

[0024] When the edge battery is overheated, the same as the middle battery, the corresponding first slider 12 is driven to slide at the beginning by the same principle, so that the corresponding first connector 18 is away from one of the electrodes of the single battery 3. The difference is that the single battery 3 is located at the edge and is externally connected to the fourth connector 21. It is worth noting that the fourth connector 21 is electrically connected to the device or other battery pack through an external wire, and the sliding of the fourth connector 21 will not affect the connection of the external device or other battery pack. Figure 6 As shown, during the sliding of the first slider 12, the first rack 22 is driven to slide, the first rack 22 drives the gear 24 to rotate, the gear 24 drives the second rack 23 to rotate, thereby driving the fourth connector 21 close to the third connector 20, so that the external device skips the edge battery through the third connector 20 and the fourth connector 21 and is directly connected to its adjacent battery.

[0025] It is worth noting that, in the above-mentioned high temperature phenomenon, after the temperature is restored, the airbag 36 recovers its deformation, and the cooling tube 27 is pulled back to its original position by the second spring 37, so that the first slider 12 and the second slider 13 are reset, and the battery is reconnected with other batteries.

[0026] The evaporation degree of the evaporating liquid is different at different temperatures, and the height of the cooling tube 27 is also different. When the temperature is too high, when the cooling tube 27 is lifted to the highest position, it is judged that the single battery 3 is not suitable for continued use and needs to be maintained or recycled. At this time, the first slider 12 and the second slider 13 are quickly approached until the first clamp 38 and the second clamp 39 are clamped and limited to each other (it is worth noting that the first clamp 38 and the second clamp 39 are common clamps on the market, and the purpose is only to limit the reset of the first slider 12 and the second slider 13). At this time, when the cooling tube 27 is raised to the highest position, the magnetic block at its end is aligned with the magnetic protrusion 9, and the magnetic protrusion 9 is pushed out of the limiting groove 10 by the repulsive force. At this time, the separation plate 7 and the connecting plate 8 slide downward under the pull of the first spring 11, thereby pushing the overheated battery downward. After the baffle 44 leaves the slide groove 6, it is gradually reset under the action of elasticity, that is, it is gradually separated from the bottom end of the battery, so that the battery is separated from the connecting plate 8 and falls into the recycling box 2 below.

[0027] refer to Figure 1-Figure 8A cooling box 41 is provided on one side of the box body 1, and a plurality of first cooling chambers 42 and a second cooling chamber 43 are provided in the cooling box 41. A first air outlet pipe 28 communicating with the first cooling chamber 42 is provided in the detection box 4, and a second air outlet pipe 29 communicating with the second cooling chamber 43 is provided in the detection box 4. The end of the second air outlet pipe 29 is communicated with the side wall of the first air outlet pipe 28. A plurality of nozzles 35 are provided on the cooling pipe 27, and a plug 34 is connected to the top wall of the cooling pipe 27. When the plug 34 moves upward, it is inserted into the end of the first air outlet pipe 28. An adjusting pipe 30 is commonly connected to the side walls of the first air outlet pipe 28 and the second air outlet pipe 29. An adjusting plate 31 is movably inserted in the adjusting pipe 30, and an adjusting hole is provided on the adjusting plate 31. A transmission plate 32 is fixedly installed on the bottom end of the adjusting plate 31, and a second pressing block 33 is fixedly installed on the top wall of the cooling pipe 27.

[0028] Under the above high temperature condition, the cooling tube 27 moves upward, so that the insert tube 34 is inserted into the first air outlet pipe 28. Figure 5 As shown, the second pressing block 33 moves up to squeeze the adjusting plate 31, so that the adjusting hole on the adjusting plate 31 is gradually aligned with the inner hole of the first air outlet pipe 28, so that the air in the first cooling chamber 42 is introduced into the cooling pipe 27 and sprayed out through multiple nozzles 35 to cool the outside of the battery. When the temperature of the battery is high, the lifting height of the second pressing block 33 increases, so that the rising height of the adjusting plate 31 increases, so that the adjusting hole on the adjusting plate 31 can be gradually aligned and connected with the inner hole of the second air outlet pipe 29. The adjusting hole on the adjusting plate 31 is larger than the size of the inner holes of the first air outlet pipe 28 and the second air outlet pipe 29, so that more air and air with lower temperature will be sprayed on the outside of the battery to achieve a cooling effect.

[0029] It is worth noting that compressed air is provided in both the first cooling chamber 42 and the second cooling chamber 43 , and the air temperature in the second cooling chamber 43 is lower in comparison.
