[0001] The present application relates to the technical field of CCS battery frames, and in particular to a CCS battery frame structure. Background Art

[0002] CCS battery, or Cell Connection System, is a key component used to connect individual battery cells in a battery module.

[0003] It is mainly responsible for realizing high-voltage series and parallel connections between battery cells, as well as collecting temperature and voltage, to ensure the normal operation and safety of the battery system. Through the highly integrated design of the CCS integrated busbar, the safety, reliability, compactness and small size of the battery module can be improved, saving space, facilitating automated assembly, and suitable for large-scale mass production. It is widely used in new energy vehicles and energy storage equipment.

[0004] The CCS integrated busbar is an electrical connection structure inside the battery module. It integrates multiple components to achieve high-voltage series and parallel connection of battery cells and temperature and voltage sampling functions of the battery.

[0005] When the existing CCS battery frame structure dissipates heat from the battery cells inside the device, the internal heat sink is basically in a normally open state due to the high operating temperature of the battery cells, which increases maintenance costs and energy consumption. At the same time, when the CCS integrated busbar collects the temperature and voltage of the battery cells, the heat accumulates seriously due to the dense welding points of the pins and the relatively large resistance of the welding points. Summary of the invention

[0006] The present application provides a CCS battery frame structure, which can solve the problem that when the existing CCS battery frame structure uses a heat sink to dissipate heat from the battery cell, the normally open heat sink increases the extra energy consumption, and the existing CCS integrated busbar has serious heat accumulation at its pins when collecting the temperature and voltage of the battery cell.

[0007] The technical solution of the present application is as follows: A CCS battery frame structure, comprising: An insulating main board, wherein a plurality of aluminum bars are disposed on both sides of the upper surface of the insulating main board, the plurality of aluminum bars are arranged at intervals along the length direction of the insulating main board and are electrically connected to the battery cells; An information collection board, wherein the information collection board is provided with pins connected to the plurality of aluminum bars in a one-to-one correspondence; A plurality of heat absorbing members with coolant inside are arranged at intervals below the insulating main board and between two adjacent battery cells; Strip cavities extending along the length direction of the insulating main board are arranged on both sides of the interior of the insulating main board, and the two strip cavities are respectively located below the two columns of the pins. A strip thermal pad is also arranged above the strip cavities on the surface of the insulating main board, and the upper surface of the strip thermal pad is in contact with the pins. A heat dissipation pipe, two ends of which are respectively connected to two ends of the strip-shaped cavity; The upper end of the heat absorbing component is communicated with the strip-shaped cavity, and the lower end is communicated with the middle part of the heat dissipation pipeline.

[0008] By adopting the above scheme, a heat-absorbing component with a coolant inside is provided, and the coolant is connected with the heat dissipation pipe and the information acquisition board, so that the coolant inside can absorb the heat of the battery core while absorbing the heat at the pins of the information acquisition board, thereby alleviating the problem of serious heat accumulation due to dense welding points at the pins. At the same time, the principle of thermal expansion of the coolant is utilized, so that the coolant can automatically circulate in the heat-absorbing component, the heat dissipation pipe and the information acquisition board, eliminating the power input, thereby saving more energy.

[0009] In one embodiment of the present application, the strip-shaped cavity comprises: middle section; Two end sections, one end of each of the two end sections is coaxially assembled at the two ends of the middle section and is communicated with the middle section, and the other end of each end section is tilted downward and is communicated with the heat dissipation pipe.

[0010] By adopting the above scheme, the heights of the middle and two ends of the strip cavity from the ground are limited, so that a height difference is formed between the two ends and the middle of the strip cavity. The coolant after absorbing heat can flow to the two ends in the middle of the strip cavity by relying on its own partial gravity, thereby providing partial circulation power for the coolant in the entire system.

[0011] In one embodiment of the present application, the CCS battery frame structure further includes: A plurality of support rods, wherein the upper ends of the plurality of support rods are installed at intervals on both sides of the insulating main board; A bottom plate, the bottom plate is arranged below the support rod and is connected and fixed to the lower end of the support rod; A heat dissipation device is mounted on two adjacent support rods.

[0012] In one embodiment of the present application, the CCS battery frame structure further includes a sensing structure, an active cavity communicating with the middle section is opened on one side of the middle section, and the sensing structure is arranged in the active cavity, and the sensing structure includes: A sealing block, wherein the sealing block is sealingly assembled in the active cavity; A temperature sensing probe, one end of which is arranged on the inner wall of the bottom end of the active cavity and is electrically connected to the heat dissipation device, and the other end of which passes through the sealing block and extends to the inside of the active cavity.

[0013] By adopting the above scheme, after the coolant absorbs heat, the coolant located in the strip cavity absorbs the temperature of the battery cell and the pin, and when the temperature rises to the preset value of the temperature sensing probe, the temperature sensing probe turns on the heat dissipation device to perform emergency heat dissipation on the battery cell, thereby avoiding safety hazards caused by excessive temperature of the battery cell. Based on the cooling of the coolant that has no power input and can self-circulate inside the device, it is more energy-efficient than the existing technical scheme of directly using a temperature switch to control the heat sink for heat dissipation.

[0014] In one embodiment of the present application, the heat absorbing member is a metal hollow plate, and a plurality of heat conductive sheets in a rectangular array are provided on both sides of the heat absorbing member close to the battery core, and the two sides of the heat conductive sheets are respectively bonded to the heat absorbing member and the battery core.

[0015] By adopting the above solution, by arranging heat conducting sheets on both side surfaces of the heat absorbing member, the temperature of the battery core can be transferred to the heat absorbing member more efficiently and quickly by the heat conducting sheets, so that the heat is absorbed by the coolant inside the heat absorbing member.

[0016] In one embodiment of the present application, the plurality of pins are divided into two columns which are spaced apart and extend along the length direction of the information acquisition board, and each of the pins is electrically connected to the corresponding aluminum bar through a temperature and voltage acquisition unit.

[0017] In one embodiment of the present application, the temperature and voltage acquisition unit includes: A circuit board for collecting voltage, wherein the circuit board is electrically connected to the pin; a thermistor, the thermistor being disposed on the circuit board and electrically connected to the circuit board; A nickel sheet, wherein the lower surface of the nickel sheet is mounted on the aluminum bar and electrically connected to the aluminum bar, and the upper surface of the nickel sheet is electrically connected to the circuit board.

[0018] By adopting the above solution, the thermistor is integrated on the circuit board for collecting voltage. Therefore, in the process of connecting the temperature and voltage collection unit with the aluminum battery, only one nickel sheet is needed to complete the function of collecting the battery cell temperature and voltage, thus saving costs.

[0019] In one embodiment of the present application, the coolant is toluene or ethanol liquid.

[0020] By adopting the above scheme, toluene or ethanol liquid with a larger thermal expansion coefficient is used as the coolant, which has a better heat absorption effect. At the same time, after absorbing heat, the density changes more greatly, thereby facilitating the self-circulation of the coolant inside the device and reducing energy loss.

[0021] In one embodiment of the present application, the CCS battery frame structure also includes a guide column, and a plurality of mounting grooves arranged at intervals along the front-to-back direction are provided on both sides of the insulating main board, and a plurality of aluminum bars are arranged in the plurality of mounting grooves in a one-to-one correspondence, and the guide column is vertically assembled inside the mounting groove, and a guide hole matching the guide column is provided in the aluminum bar.

[0022] By adopting the above solution, by setting the guide column, the aluminum bar can be accurately assembled in the installation groove by using the guide column, thereby improving the stability of the aluminum bar during installation to ensure the stability during electrical connection.

[0023] In one embodiment of the present application, the CCS battery frame structure further includes: A plurality of support rods, wherein the upper ends of the plurality of support rods are installed at intervals on both sides of the insulating main board; A bottom plate is arranged below the support rod and is connected and fixed to the lower end of the support rod.

[0024] In one embodiment of the present application, the CCS battery frame structure further includes a first connecting tube and a second connecting tube; One end of the first connecting pipe is assembled on the end section and communicated with it, and the other end of the first connecting pipe is connected and fixed to the heat dissipation pipe and communicated with the heat dissipation pipe; The second connecting pipe is assembled on the supporting rod and passes through the supporting rod. One end of the second connecting pipe is connected and fixed to the lower end of the heat absorbing component, and the other end is communicated with the heat dissipation pipe.

[0025] By adopting the above solution, the entire CCS integrated busbar is propped up by setting support rods, and the battery cells are installed in the gaps between the support rods. This can not only support and protect the battery cells, but also increase the contact area between the battery cells and the external air, thereby improving the heat dissipation effect of the device.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By using ethanol or toluene solution as the coolant, the heat accumulated between the battery cells is absorbed by the heat absorbing component. The coolant expands after absorbing the heat and rises to the strip cavity. The heat from the pin can be absorbed again through the strip thermal pad. The coolant after absorbing the heat expands due to heat absorption. The coolant itself circulates in the strip cavity, the heat absorbing component and the heat dissipation pipeline, thereby avoiding additional power input for the device, and can also use liquid cooling to dissipate the heat of the battery cells, reducing energy consumption.

[0027] 2. By integrating the thermistor on the circuit board for voltage collection, when assembling the circuit board and collecting the temperature and voltage of the battery cell, compared with separately assembling the thermistor and the circuit board on the aluminum bar using nickel sheets, it is only necessary to assemble the circuit board with the thermistor on the rate dam to realize the collection of the parameters of the battery cell temperature and voltage, thereby saving the processing cost of the device.

[0028] 3. By adopting an induction structure, on the basis of the self-circulation of coolant without power input to dissipate heat for the device, a heat dissipation device capable of sensing the coolant temperature is added. By sensing the coolant temperature, the heat absorption capacity of the coolant to the internal heat of the device can be judged. Compared with the existing technical solution of directly using a temperature sensor to control the heat dissipation device, the heat dissipation device will not remain in a normally open state due to the continuously high operating temperature of the battery cell. Therefore, it is more energy-efficient while ensuring electricity safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-7 A CCS battery frame structure provided in the present application is further described in detail.

[0032] See also Figure 1 , is a CCS battery frame structure provided in an embodiment of the present application, comprising: an insulating main board 1, an information collection board 2, multiple groups of heat absorbing parts 3, a temperature and voltage collection unit 4 and a heat dissipation pipe 5, a plurality of aluminum bars 14 are arranged on both sides of the upper surface of the insulating main board 1, and the plurality of aluminum bars 14 are arranged at intervals along the length direction of the insulating main board 1 and are electrically connected to the battery cells, and the information collection board 2 is provided with pins 21 connected to the plurality of aluminum bars 14 in a one-to-one correspondence, a coolant is provided inside the heat absorbing part 3, and multiple groups of the heat absorbing parts 3 are arranged at intervals below the insulating main board 1 and are located between two adjacent battery cells, and a strip cavity 15 extending along the length direction of the insulating main board 1 is arranged on both sides of the interior of the insulating main board 1, and the two strip cavities 15 are arranged. The cavities 15 are respectively located below the two rows of pins 21. A strip-shaped thermal pad 16 is further provided on the surface of the insulating main board 1 above the strip-shaped cavity 15. The upper surface of the strip-shaped thermal pad 16 is in contact with the pins 21. The heat dissipation pipe 5 has two ends respectively connected with the two ends of the strip-shaped cavity 15. The upper end of the heat absorption component 3 is connected with the strip-shaped cavity 15, and the lower end is connected with the middle part of the heat dissipation pipe 5. When the coolant is used for heat dissipation, the coolant absorbs heat and expands, thereby causing the coolant to rise, and the coolant with low external temperature and high density is replenished, thereby realizing the circulation of the coolant, reducing the input of electricity, and ensuring a good cooling and heat dissipation effect. At the same time, during the circulation process, the heat dissipation effect at the pin 21 is further improved.

[0033] The temperature and voltage acquisition unit 4 can be assembled by mounting and welding, using components that can simultaneously collect temperature and voltage. Therefore, during assembly, only one mounting and welding operation is required to collect the temperature and voltage of the battery cell 8.

[0034] When the coolant is poured, it is in the heat absorbing element 3 , the strip cavity 15 and the heat dissipation pipe 5 at the same time, and the coolant fills the heat absorbing element 3 , the strip cavity 15 and the heat dissipation pipe 5 .

[0035] A water-cooled radiator (not shown) may also be provided, and the liquid inlet and liquid outlet of the water-cooled radiator are respectively connected to the heat dissipation pipe 5, so that the coolant enters the water-cooled radiator to accelerate the heat dissipation, thereby improving the heat dissipation speed of the coolant.

[0036] In this embodiment, the information collection board 2 can be an aluminum nitride or silicon carbide component, which has good thermal conductivity and insulation.

[0037] See also Figure 4 The strip cavity 15 includes: a middle section 151 and two end sections 152. One end of the two end sections 152 is coaxially assembled at the two ends of the middle section 151 and communicated with the middle section 151. The other end of the end section 152 is tilted downward and communicated with the heat dissipation pipe 5. By setting the strip cavity 15 with a high middle part and low ends, the coolant expands due to heat, and after entering from the middle part of the strip cavity 15, it can flow to the two ends of the strip cavity 15 under the action of its own gravity, thereby improving the circulation speed of the coolant.

[0038] See also Figure 1 The CCS battery frame structure also includes: a plurality of support rods 6, a bottom plate 7 and a heat sink 9, wherein the upper ends of the plurality of support rods 6 are spaced apart and installed on both sides of the insulating main board 1, the bottom plate 7 is arranged below the support rods 6 and is connected and fixed to the lower ends of the support rods 6, and the heat sink 9 is installed on two adjacent support rods 6, wherein the heat dissipation pipe 5 can be arranged outside the support rod 6, and the length of the heat dissipation pipe 5 is greater than the length of the bottom plate 7, so that the heat dissipation pipe 5 has sufficient length to extend to the outside of the device, thereby ensuring that the temperature difference between the coolant inside the heat dissipation pipe 5 outside the device and the coolant inside the heat absorption component 3 is large enough for circulation.

[0039] See also Figure 6 and Figure 7The CCS battery frame structure also includes a sensing structure 153. An active cavity 1511 communicating with the middle section 151 is opened on one side of the middle section 151. The sensing structure 153 is arranged in the active cavity 1511. The sensing structure 153 includes: a sealing block 1531 and a temperature sensing probe 1532. The sealing block 1531 is sealed and assembled in the active cavity 1511. One end of the temperature sensing probe 1532 is arranged on the inner wall of the bottom end of the active cavity 1511 and is electrically connected to the heat dissipation device 9. The other end penetrates The sealing block 1531 extends into the active cavity 1511, and a temperature sensing probe 1532 capable of sensing the temperature of the coolant is provided to judge the cooling and heat dissipation capacity of the coolant. Compared with the existing technical means of directly sensing the temperature of the battery cell by a temperature sensing device and controlling the heat dissipation device to dissipate heat, by using the coolant to absorb heat from the battery cell 8 in advance, it is avoided that the heat dissipation device is always in a working state due to the continuously high temperature of the battery cell 8 during operation, thereby ensuring the safety of the device's electricity use and being more energy-efficient.

[0040] The heat dissipation device 9 is a heat dissipation fan, which is used to be turned on to achieve emergency heat dissipation when the heat absorption capacity of the coolant is insufficient.

[0041] See also Figure 3 The heat absorbing member 3 is a metal hollow plate, and a plurality of heat conducting sheets 31 in a rectangular array are arranged on both sides of the heat absorbing member 3 close to the battery core, and the two sides of the heat conducting sheets 31 are respectively attached to the heat absorbing member 3 and the battery core 8, wherein the heat conducting sheet 31 can be a sheet-shaped heat conducting gel sheet, and the two sides of the heat conducting sheet 31 are respectively attached to the heat absorbing member 3 and the battery core 8, and the heat conducting gel sheet is mounted between the battery core 8 and the heat absorbing member 3, so that the temperature inside the battery core 8 can be quickly conducted into the heat absorbing member 3 to complete the rapid transfer of heat, thereby improving the cooling effect of the device on the internal battery core 8.

[0042] In this embodiment, the heat absorbing member 3 may be a copper member.

[0043] See also Figure 2The temperature and voltage acquisition unit 4 includes: a circuit board 41 for collecting voltage, a thermistor 42 and a nickel sheet 43, the circuit board 41 is electrically connected to the pin 21, the thermistor 42 is arranged on the circuit board 41 and electrically connected to the circuit board 41, the lower surface of the nickel sheet 43 is assembled on the aluminum bar 14 and electrically connected to the aluminum bar 14, and the upper surface of the nickel sheet 43 is electrically connected to the circuit board 41. When assembling the circuit board 41 and electrically connecting the circuit board 41 with the pin 21 and the aluminum bar 14, a connecting groove can be opened on the aluminum bar 14, and the nickel sheet 43 can be welded in the connecting groove, and one end of the circuit board 41 is electrically connected to the nickel sheet 43, and the other end of the circuit board 41 is electrically connected to the pin 21, so as to realize data collection of temperature and voltage parameters of the battery cell 8 inside the device.

[0044] Among them, the depth of the connecting groove is equal to the thickness of the nickel sheet 43, so that when one end of the circuit board 41 is assembled on the nickel sheet 43, its other end can just contact the insulating main board 1, so that the two ends of the circuit board 41 are arranged on the same plane formed by the nickel sheet 43 and the insulating main board 1, so that the two ends of the circuit board 41 are subjected to more uniform force, avoiding the formation of a cantilever structure.

[0045] In this embodiment, a fuse may be further provided on the circuit board 41. When overloaded, the fuse blows, thereby protecting the circuit.

[0046] The electrical connection means between the fuse and thermistor 42 and the circuit board 41 itself are conventional technical means, so they are not described here in detail.

[0047] The coolant is toluene or ethanol liquid. By setting toluene or ethanol as the coolant inside the device and utilizing its large thermal expansion coefficient, the device can achieve self-circulation of the coolant under the action of the temperature difference after absorbing heat.

[0048] See also Figure 1 The CCS battery frame structure also includes a guide column 12. Both sides of the insulating main board 1 are provided with a plurality of mounting grooves 11 spaced apart along the front-to-back direction. The plurality of aluminum bars 14 are arranged in the plurality of mounting grooves 11 in a one-to-one correspondence. The guide column 12 is vertically assembled inside the mounting groove 11. The aluminum bar 14 is provided with a guide hole matched with the guide column 12. When assembling the aluminum bar 14, the guide hole on the aluminum bar 14 is firstly used to face the guide column 12 in the mounting groove 11, so as to facilitate the positioning of the aluminum bar 14 during installation. Then, the aluminum bar 14 is inserted into the mounting groove 11, and the aluminum bar 14 is fixed inside the mounting groove 11 by welding, thereby improving the installation stability of the aluminum bar 14, and further improving the stability effect when the aluminum bar 14 is electrically connected to the battery cell 8.

[0049] See also Figure 1 The CCS battery frame structure also includes a first connecting tube 13 and a second connecting tube 61, one end of the first connecting tube 13 is assembled on the end section 152 and communicated with it, the other end of the first connecting tube 13 is connected and fixed to the heat dissipation pipe 5 and communicated with the heat dissipation pipe 5, the second connecting tube 61 is assembled on the support rod 6 and passes through the support rod 6, one end of the second connecting tube 61 is connected and fixed to the lower end of the heat absorption component 3, and the other end is communicated with the heat dissipation pipe 5.

[0050] In summary, when the device is working, first, the coolant inside the heat absorbing element 3 expands after absorbing the heat of the battery core 8, and rises into the strip cavity 15. Since the strip cavity 15 is arranged below the pin 21, the heat dissipated from the connection between the pin 21 and the circuit board 41 can be quickly absorbed by the coolant inside the strip cavity 15. The coolant that absorbs the heat flows out through the first connecting pipes 13 at both ends of the strip cavity 15, and is cooled back to the second connecting pipe 61 under the heat dissipation of the heat dissipation pipe 5 arranged outside the device, and flows back into the bottom of the heat absorbing element 3, thereby realizing the circulation of the coolant without power input. When the temperature sensing probe 1532 detects that the coolant temperature rises to a preset value, the temperature sensing probe 1532 turns on the heat dissipation device 9, and the heat dissipation device 9 assists in dissipating the heat of the entire device and the coolant inside, thereby ensuring the safety of electricity use and being more energy-efficient than existing technical means.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
