[0014] According to the battery of this application, the structural design of the first cooling component being adapted to seal the opening on the rear side of the first cavity and the second cooling component being adapted to seal the opening on the front side of the second cavity simplifies the mold design of the front beam and the rear beam, improves the uniformity of the wall thickness of the front beam and the rear beam, reduces the risk of air holes and shrinkage cavities in the front beam and the rear beam, and significantly reduces the weight of the front beam and the rear beam, thereby increasing the usable space of the first cavity and the second cavity.

This provides a structural basis for the flow path design of the cooling medium first cooling the battery cell and then partially shunt cooling the battery circuit breaker unit. Furthermore, by utilizing the deformable design of the first tube and the second tube, the installation tolerances of the first connector, the second connector, the third connector, and the fourth connector can be better adapted, thereby improving the durability and reliability of the first tube and the second tube.

[0057] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0058] This application provides a battery.

[0059] The following is for reference. Figures 1-9 Description of a battery according to an embodiment of this application

[0060] In some embodiments, such as Figures 1-3 As shown, the battery includes: a housing 10, an electrical device 30, a first cooling device 40, a second cooling device 50, and at least one cell assembly 20.

[0061] The housing 10 forms an energy chamber 13 and an electrical cavity 14; the battery cell assembly 20 is installed in the energy chamber 13; the electrical equipment 30 is installed in the electrical cavity 14; a first cooling device 40 is installed in the housing 10 and is used for heat exchange with the battery cell assembly 20; a second cooling device 50 is installed in the housing 10 and is used to separate the energy chamber 13 and the electrical cavity 14, and to exchange heat with the electrical equipment 30.

[0062] like Figure 1 As shown, the battery also includes a top cover 90. The housing 10 defines an energy compartment 13 open on one side. The top cover 90 is connected to the housing 10 and is used to seal the open side of the energy compartment 13. A cell assembly 20 is housed in this energy compartment 13 and is responsible for storing and releasing electrical energy. The cell assembly 20 consists of multiple cells connected in series or in parallel to provide the required voltage and capacity. The stacking direction of the multiple cells can be along the front-to-back direction or other directions, which is not limited in this application.

[0063] The first cooling device 40 is used to dissipate heat and cool the battery cell assembly 20, wherein, for example, Figure 1 and Figure 2 As shown, the first cooling device 40 can be a cold plate, and a cooling medium flows inside it. The cooling medium can be, but is not limited to, refrigerant, ethylene glycol aqueous solution, propylene glycol aqueous solution or water, etc. There are no restrictions here.

[0064] For example, in some embodiments, a refrigerant flows inside the first cooling device 40, meaning that the first cooling device 40 is connected to the vehicle's refrigeration system.

[0065] The first cooling device 40 may be located at at least one of the bottom, top and side of the cell assembly 20, and this application does not limit it.

[0066] For example, in some embodiments, the first cooling device 40 is located at the bottom of the cell assembly 20.

[0067] Electrical equipment 30 is responsible for monitoring and managing the charging and discharging process of the battery. Specifically, it may include, but is not limited to, a battery management system, a protection circuit, or a charging and discharging control circuit.

[0068] The second cooling device 50 is used to dissipate heat and cool the electrical equipment 30, wherein, for example... Figure 1 and Figure 3As shown, the second cooling device 50 can be a cold plate, and a cooling medium flows inside it. The cooling medium can be, but is not limited to, refrigerant, ethylene glycol aqueous solution, propylene glycol aqueous solution, or water, etc. There are no restrictions here.

[0069] For example, in some embodiments, a refrigerant flows inside the first cooling device 40, meaning that the first cooling device 40 is connected to the vehicle's refrigeration system.

[0070] The second cooling device 50 also serves to separate the energy chamber 13 and the electrical cavity 14, preventing heat and electromagnetic interference from transferring between them. For example, Figure 1 As shown, the two sides of the second cooling device 50 are connected to the energy chamber 13 and the electrical cavity 14 respectively, and the second cooling device 50 is placed vertically, that is, the large surface of the second cooling device 50 is parallel to the vertical surface.

[0071] Understandably, on the one hand, by introducing the first cooling device 40 and the second cooling device 50 into the battery, the heat dissipation requirements of both the battery cell and the electrical equipment 30 are met simultaneously, filling the gap in the lack of a cooling mechanism for the electrical equipment 30 in existing battery designs. Through an efficient heat exchange mechanism, the second cooling device 50 can effectively reduce the temperature of the internal components of the electrical equipment 30, thereby alleviating the situation where the electrical equipment 30 heats up during high-current charging and discharging, resulting in limited fast charging time. At the same time, this design also reduces the risk of heat transfer to the battery cell assembly 20, further improving the safety and stability of the entire battery. On the other hand, since the original battery housing 10 design usually sets up an isolation structure, such as a separator or partition rib, between the electrical cavity 14 and the energy chamber 13, if the second cooling device 50 is added on top of the isolation structure, the overall structure will become redundant. Thus, the second cooling device 50 of this application, while performing the original cooling function, also replaces the original isolation structure, reducing the weight of the housing 10 without affecting the volume utilization rate of the housing 10, achieving optimization and lightweighting of the battery structure.

[0072] The battery provided in this application embodiment, by adding a second cooling device 50 inside the housing 10 as described above, effectively cools the electrical equipment 30, significantly reduces the temperature of the internal components of the electrical equipment 30 during high-current charging and discharging, thereby extending the high-current charging and discharging time and improving the service life of the electrical equipment 30. At the same time, it also reduces the transfer of heat from the electrical equipment 30 to the cell assembly 20, alleviating the domino effect of thermal runaway of the cell assembly 20 caused by excessive temperature of the electrical equipment 30. Furthermore, the second cooling device 50 replaces the original isolation structure on the housing 10, simplifies the structure of the housing 10, realizes overall miniaturization and lightweight design, and maintains high volume utilization.

[0073] In some embodiments, such as Figure 1 and Figure 2 As shown, the electrical equipment 30 includes a battery circuit breaker unit 30A and a high-voltage power distribution unit 30B. The electrical cavity 14 includes a first cavity 1111 and a second cavity 1131 located on different sides of the energy chamber 13. The second cooling device 50 includes a first cooling element 50A and a second cooling element 50B. The battery circuit breaker unit 30A is installed in the first cavity 1111 and is used for heat exchange with the first cooling element 50A. The first cooling element 50A is used to separate the energy chamber 13 and the first cavity 1111. The high-voltage power distribution unit 30B is installed in the second cavity 1131 and is used for heat exchange with the second cooling element 50B. The second cooling element 50B is used to separate the energy chamber 13 and the second cavity 1131.

[0074] It should be noted that both BDU (Battery Disconnect Unit, 30A) and PDU (Power Distribution Unit, 30B) are battery distribution boxes. Specifically, in common battery designs, the battery disconnect unit 30A is a small distribution box for the battery, while the high-voltage distribution unit 30B is a large distribution box for the battery.

[0075] The BDU (Battery Disconnect Unit 30A) is responsible for disconnecting the electrical connection between the battery and the load when necessary to prevent damage to the battery and system caused by abnormal conditions such as overcurrent or short circuit. The PDU (Power Distribution Unit 30B) is responsible for the distribution and control of the high-voltage circuit in the battery to ensure that the battery can safely and efficiently supply power to the load.

[0076] The electrical cavity 14 is subdivided into a first cavity 1111 and a second cavity 1131 located on different sides of the energy chamber 13. Specifically, the first cavity 1111 and the second cavity 1131 can be arranged adjacent to each other or opposite to each other. This application does not limit this.

[0077] The second cooling device 50 is further divided into a first cooling element 50A and a second cooling element 50B, which are responsible for the heat management of the first cavity 1111 and the second cavity 1131, respectively.

[0078] Among them, such as Figure 1 and Figure 2As shown, the first cooling element 50A is used for heat exchange with the battery circuit breaker unit 30A, maintaining the battery circuit breaker unit 30A at a safe operating temperature. Simultaneously, the first cooling element 50A also serves as a physical barrier, separating the energy chamber 13 and the first cavity 1111, preventing the transfer of heat and potential electrical risks between the energy chamber 13 and the first cavity 1111. The second cooling element 50B is used for heat exchange with the high-voltage power distribution unit 30B, maintaining the high-voltage power distribution unit 30B at a safe operating temperature. Simultaneously, the second cooling element 50B also serves as a physical barrier, separating the energy chamber 13 and the second cavity 1131, preventing the transfer of heat and potential electrical risks between the energy chamber 13 and the second cavity 1131.

[0079] It should be noted that, since the heat dissipation requirements of the cell pack 20, the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B are different, in the actual design, the dimensions, liquid inlet temperature or liquid inlet volume of the first cooling device 40, the first cooling component 50A and the second cooling component 50B can be customized according to the actual needs of the cell pack 20, the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B.

[0080] The battery provided in this application embodiment is designed to cool the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B respectively through the first cooling element 50A and the second cooling element 50B. Combined with the structural basis of the first cooling device 40, it realizes the independent cooling of the cell group 20, the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B in different zones, taking into account the cooling needs of the cell group 20, the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B, reducing the probability of local over-cooling or inadequate cooling. Furthermore, by accommodating the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B in the first cavity 1111 and the second cavity 1131 on different sides respectively, and separating the first cavity 1111 and the second cavity 1131 from the energy chamber 13 using the first cooling element 50A and the second cooling element 50B respectively, the electrical interference between the cell group 20, the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B is reduced, thereby improving the overall performance and stability of the battery.

[0081] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 10 includes a frame 11, which includes a front beam 111, a left beam 112, a rear beam 113, and a right beam 114 arranged around it. The front beam 111 forms a first cavity 1111 that protrudes forward, and a first cooling component 50A is adapted to block the opening on the rear side of the first cavity 1111. The rear beam 113 forms a second cavity 1131 that protrudes rearward, and a second cooling component 50B is adapted to block the opening on the front side of the second cavity 1131.

[0082] The frame 11, as the main structure of the housing 10, consists of a front beam 111, a left beam 112, a rear beam 113, and a right beam 114, forming a closed frame that provides support and protection for the battery pack 20, electrical equipment 30, and cooling device. The front beam 111, left beam 112, rear beam 113, and right beam 114 can be formed by die casting or other processes.

[0083] The front beam 111 has a forward-protruding portion to form a space for the first cavity 1111, so that the first cavity 1111 is located at the front of the housing 10, which facilitates the installation of the battery disconnect unit 30A and the first cooling component 50A. The first cooling component 50A seals the opening on the rear side of the first cavity 1111, thereby separating the first cavity 1111 from the energy compartment 13, while contacting the battery disconnect unit 30A for effective heat exchange.

[0084] The first cooling component 50A can be customized according to the size and shape of the opening on the rear side of the first cavity 1111.

[0085] The rear beam 113 has a rearward protruding portion to form a space for the second cavity 1131, so that the second cavity 1131 is located at the rear of the housing 10, which facilitates the installation of the high-voltage power distribution unit 30B and the second cooling component 50B. The second cooling component 50B blocks the opening on the front side of the second cavity 1131, thereby separating the second cavity 1131 from the energy chamber 13, while contacting the high-voltage power distribution unit 30B for effective heat exchange.

[0086] The second cooling element 50B can be customized according to the size and shape of the opening on the front side of the second cavity 1131.

[0087] In related technologies, both the front and rear beams have an integrally formed isolation structure to provide thermoelectric isolation in the event of thermal runaway of the battery pack. However, in practical applications, during the manufacturing process of the front and rear beams, the presence of the isolation structure means that both beams can only be demolded in one direction. Furthermore, to achieve smooth demolding, numerous protruding structures exist within the internal cavities of the front and rear beams. This not only complicates the mold design of the front and rear beams but also results in uneven wall thickness, increasing the probability of porosity and shrinkage cavities. In addition, these protruding structures occupy space within the internal cavities and significantly increase the weight of the front and rear beams themselves.

[0088] Understandably, based on the fact that the first cooling component 50A is suitable for sealing the opening on the rear side of the first cavity 1111, and the second cooling component 50B is suitable for sealing the opening on the front side of the second cavity 1131, the first cooling component 50A and the second cooling component 50B respectively replace the original isolation structures of the front beam 111 and the rear beam 113. On the one hand, using this structure adds a demolding direction for the front beam 111 and the rear beam 113, avoiding the generation of a large number of protruding structures on the inner walls of the first cavity 1111 and the second cavity 1131, thereby simplifying the mold design of the front beam 111 and the rear beam 113, improving the uniformity of the wall thickness of the front beam 111 and the rear beam 113, and reducing the risk of air holes and shrinkage cavities in the front beam 111 and the rear beam 113; on the other hand, due to the sharp reduction of protruding structures, the weight of the front beam 111 and the rear beam 113 is also greatly reduced, while also increasing the usable space of the first cavity 1111 and the second cavity 1131.

[0089] The battery provided in this application embodiment, through the structural design of the first cooling component 50A being adapted to block the opening on the rear side of the first cavity 1111 and the second cooling component 50B being adapted to block the opening on the front side of the second cavity 1131, simplifies the mold design of the front beam 111 and the rear beam 113, improves the uniformity of the wall thickness of the front beam 111 and the rear beam 113, reduces the risk of air holes and shrinkage cavities in the front beam 111 and the rear beam 113, and significantly reduces the weight of the front beam 111 and the rear beam 113, thereby increasing the usable space of the first cavity 1111 and the second cavity 1131.

[0090] In some embodiments, the flow channels of the first cooling element 50A and the second cooling element 50B are connected in parallel, and the flow channels of the first cooling element 50A and the second cooling element 50B connected in parallel are connected in series with the flow channels of the first cooling device 40. The liquid inlet 1112 of the battery is connected to the flow channel inlet of the first cooling device 40, and the liquid outlet 1113 of the battery is connected to the flow channel outlet of the first cooling element 50A and the flow channel outlet of the second cooling element 50B.

[0091] It should be noted that the optimal operating temperature of the battery cell is typically 20℃~30℃, while the optimal operating temperature of the components in the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B is typically 55℃~65℃. Therefore, if the first cooling device 40, the first cooling element 50A, and the second cooling element 50B each have separate inlet and outlet liquid levels, a large number of piping assemblies would be required, which would be detrimental to cost control and make the installation process overly complex.

[0092] In actual operation, after the cooling medium enters the battery through the inlet 1112, it first enters the flow channel of the first cooling device 40. After exchanging heat with the cell assembly 20, the temperature of the cooling medium can reach 25℃~35℃. The flow channel of the first cooling device 40 includes multiple branches. The cooling medium in one branch then enters the first cooling element 50A to exchange heat with the battery circuit breaker unit 30A, while the cooling medium in another branch then enters the second cooling element 50B to exchange heat with the high-voltage power distribution unit 30B. The cooling medium after exchanging heat with the battery circuit breaker unit 30A and the cooling medium after exchanging heat with the high-voltage power distribution unit 30B merge and flow to the battery outlet 1113, finally returning to the compressor. In this way, the cooling medium first passes through the first cooling device 40 and then flows separately to the first cooling element 50A and the second cooling element 50B. This has no negative impact on the cooling effect of the cell assembly while meeting the cooling requirements of the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B.

[0093] The battery provided in this application embodiment, through the flow path layout design of the first cooling device 40, the first cooling component 50A and the second cooling component 50B, realizes that the cooling medium first cools the battery cell and then separately distributes to the cooling battery circuit breaker unit 30A and the high-voltage power distribution unit 30B. It takes into account the different water inlet temperature requirements of the battery cell, the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B, reduces the overall energy consumption, reduces the number of pipes and connectors, and reduces manufacturing costs and maintenance difficulty.

[0094] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, the first cooling device 40 also includes a first transition channel and a second transition channel (not shown in the figure) spaced apart from the flow channel. The inlet of the first transition channel is connected to the flow channel outlet of the first cooling element 50A, and the outlet of the first transition channel is connected to the liquid outlet 1113 of the battery. The inlet of the second transition channel is connected to the flow channel outlet of the second cooling element 50B, and the outlet of the second transition channel is connected to the liquid outlet 1113 of the battery.

[0095] The first cooling device 40 internally includes a first transition channel and a second transition channel spaced apart from its own flow channel. The flow channel of the first cooling device 40 is used to cool the battery cells. The first transition channel serves as an intermediate transition area before the high-temperature cooling medium flows from the first cooling element 50A back to the battery outlet 1113. The second transition channel serves as an intermediate transition area before the high-temperature cooling medium flows from the second cooling element 50B back to the battery outlet 1113. Separating the flow channel of the first cooling device 40 from the introduced first and second transition channels minimizes heat transfer between the high-temperature cooling medium exiting from the first and second cooling elements 50A and 50B and the already cooled battery cell assembly 20.

[0096] For example, such as Figure 8 As shown, the battery inlet 1112 and the battery outlet 1113 are mounted side by side on the front beam 111 and are connected to the first cooling device 40 through pipes.

[0097] Understandably, by introducing a first transition channel and a second transition channel within the first cooling device 40, the high-temperature cooling medium exiting from the first cooling element 50A and the second cooling element 50B is guided by the first cooling device 40 to the battery outlet 1113. Compared to the common approach where the flow outlets of the first cooling element 50A and the second cooling element 50B are each connected to external pipes to the battery outlet 1113, this design achieves a concealed design for the first and second transition channels. The first and second transition channels do not occupy additional space, improving the space utilization of the battery. Furthermore, the manufacturing process of the first and second transition channels is simple, and they can be formed together with the flow channels of the first cooling device 40, accelerating battery production efficiency while reducing production costs.

[0098] The battery provided in this application embodiment, through the above-mentioned first transition channel and second transition channel, guides the high-temperature cooling medium from the first cooling element 50A and the second cooling element 50B to the battery outlet 1113 by means of the first cooling device 40, without occupying extra space, thereby improving the space utilization rate of the battery. Furthermore, the manufacturing process of the first transition channel and the second transition channel is simple, which speeds up the battery production efficiency while reducing the production cost.

[0099] In some embodiments, such as Figure 4 As shown, the battery also includes: a first connector 61, a first tube 71, a second connector 62, a third connector 63, a second tube 72, and a fourth connector 64.

[0100] The first connector 61 is installed at the outlet of the flow channel of the first cooling device 40, the second connector 62 is installed at the inlet of the flow channel of the first cooling component 50A, the first tube 71 is sealed between the first connector 61 and the second connector 62, and the first tube 71 is made of elastic material.

[0101] The first connector 61 can be connected to the flow channel outlet of the first cooling device 40 by brazing or other processes, and the second connector 62 can be connected to the flow channel inlet of the first cooling component 50A by brazing or other processes.

[0102] The first tube 71 is made of a deformable elastic material, designed to accommodate possible installation tolerances of the first connector 61 and the second connector 62, thereby avoiding the risk of brittle fracture of the first tube 71 that may be caused by using rigid materials.

[0103] Specifically, the elastic material may include, but is not limited to, rubber or silicone, etc., without limitation.

[0104] It should be noted that, in order to reduce the risk of leakage, a sealing element, such as a sealing ring, can be installed between the first pipe 71 and the first connector 61 and the second connector 62.

[0105] The third connector 63 is installed at the inlet of the first transition channel, the fourth connector 64 is installed at the outlet of the flow channel of the first cooling component 50A, and the second pipe 72 is sealed between the third connector 63 and the fourth connector 64, and the second pipe 72 is made of elastic material.

[0106] The third connector 63 can be connected to the inlet of the first transition channel by brazing or other processes, and the fourth connector 64 can be connected to the outlet of the flow channel of the first cooling component 50A by brazing or other processes.

[0107] The second tube 72 is made of a deformable elastic material, designed to accommodate possible installation tolerances of the third connector 63 and the fourth connector 64, thereby avoiding the risk of brittle fracture of the second tube 72 that might occur if rigid materials were used.

[0108] Specifically, the elastic material may include, but is not limited to, rubber or silicone, etc., without limitation.

[0109] It should be noted that, in order to reduce the risk of leakage, a sealing element, such as a sealing ring, can be installed between the second pipe 72 and the third connector 63 and the fourth connector 64.

[0110] In this embodiment, such as Figure 3 and Figure 4As shown, the housing 10 also includes at least one crossbeam 12 connected between the frame 11. The first cooling device 40 is clamped between the frame 11 and the cold plate. The inlet of the first transition channel can be hidden under the front beam 111. Thus, the first connector 61 and the third connector 63 need to be inserted through the front beam 111 to achieve communication with the first transition channel.

[0111] The battery provided in this application embodiment, through the arrangement of the first connector 61, the first tube 71, the second connector 62, the third connector 63, the second tube 72, and the fourth connector 64, realizes the sequential connection of the flow channel of the first cooling device 40, the flow channel of the first cooling component 50A, and the first transition channel of the first cooling device 40. This provides a structural basis for the flow path design of the cooling medium first cooling the battery cell and then partially shunt cooling the battery circuit breaker unit 30A. Furthermore, by utilizing the deformable design of the first tube 71 and the second tube 72, it is possible to better adapt to the installation tolerances of the first connector 61, the second connector 62, the third connector 63, and the fourth connector 64, thereby improving the durability and reliability of the first tube 71 and the second tube 72.

[0112] In some embodiments, such as Figure 5 As shown, the battery also includes: a fifth connector 65, a third tube 73, a sixth connector 66, a seventh connector 67, a fourth tube 74, and an eighth connector 68.

[0113] The fifth connector 65 is installed at the outlet of the flow channel of the first cooling device 40, the sixth connector 66 is installed at the inlet of the flow channel of the second cooling component 50B, and the third tube 73 is sealed between the fifth connector 65 and the sixth connector 66, and the third tube 73 is made of elastic material.

[0114] The fifth connector 65 can be connected to the flow channel outlet of the first cooling device 40 by brazing or other processes, and the second connector 62 can be connected to the flow channel inlet of the second cooling component 50B by brazing or other processes.

[0115] The third tube 73 is made of a deformable elastic material, designed to accommodate possible installation tolerances of the fifth connector 65 and the sixth connector 66, thereby avoiding the risk of brittle fracture of the third tube 73 that might occur if rigid materials were used.

[0116] Specifically, the elastic material may include, but is not limited to, rubber or silicone, etc., without limitation.

[0117] It should be noted that, in order to reduce the risk of leakage, a sealing element, such as a sealing ring, can be installed between the third pipe 73 and the fifth connector 65 and the sixth connector 66.

[0118] The seventh connector 67 is installed at the inlet of the second transition channel, the eighth connector 68 is installed at the outlet of the flow channel of the second cooling component 50B, and the fourth tube 74 is sealed between the seventh connector 67 and the eighth connector 68, and the fourth tube 74 is made of elastic material.

[0119] The seventh connector 67 can be connected to the inlet of the second transition channel by brazing or other processes, and the eighth connector 68 can be connected to the outlet of the flow channel of the second cooling component 50B by brazing or other processes.

[0120] The fourth tube 74 is made of a deformable elastic material to accommodate the installation tolerances that may occur with the seventh connector 67 and the eighth connector 68, thereby avoiding the risk of brittle fracture of the fourth tube 74 that may be caused by using rigid materials.

[0121] Specifically, the elastic material may include, but is not limited to, rubber or silicone, etc., without limitation.

[0122] It should be noted that, in order to reduce the risk of leakage, a sealing element, such as a sealing ring, can be installed between the fourth pipe 74 and the seventh connector 67 and the eighth connector 68.

[0123] In this embodiment, such as Figure 3 and Figure 5 As shown, the housing 10 also includes at least one crossbeam 12 connected between the frame 11. The first cooling device 40 is clamped between the frame 11 and the cold plate. The inlet of the second transition channel can be hidden under the rear beam 113. Thus, the fifth connector 65 and the seventh connector 67 need to be inserted through the rear beam 113 to achieve communication with the second transition channel.

[0124] The battery provided in this application embodiment, through the arrangement of the fifth connector 65, the third tube 73, the sixth connector 66, the seventh connector 67, the fourth tube 74, and the eighth connector 68, realizes the sequential connection of the flow channel of the first cooling device 40, the flow channel of the second cooling component 50B, and the second transition channel of the first cooling device 40. This provides a structural basis for the flow path design of the cooling medium first cooling the battery cell and then partially shunt cooling the high-voltage power distribution unit 30B. Furthermore, by utilizing the deformable design of the third tube 73 and the fourth tube 74, it can better adapt to the installation tolerances of the fifth connector 65, the sixth connector 66, the seventh connector 67, and the eighth connector 68, thereby improving the durability and reliability of the third tube 73 and the fourth tube 74.

[0125] In some embodiments, such as Figure 1 , Figure 2 and Figures 6-9 As shown, the battery also includes a front sealing cover 81 and a rear sealing cover 82.

[0126] The front sealing cover 81 is connected to the front beam 111 and is adapted to seal the opening on the front side of the first cavity 1111. The rear sealing cover 82 is connected to the rear beam 113 and is adapted to seal the opening on the rear side of the second cavity 1131.

[0127] The front sealing cover 81 is located at the front of the housing 10 and is positioned opposite to the first cooling component 50A in the front-rear direction. The front sealing cover 81 can be tightly connected to the front beam 111 by means of bolt connection, snap-fit ​​or riveting to maintain the sealing of the first cavity 1111.

[0128] The front sealing cover 81 can be made of a material that is corrosion-resistant, high-temperature resistant and has good sealing performance, such as stainless steel, aluminum alloy or special plastic, to reduce the entry of liquid, dust or other contaminants into the first chamber 1111.

[0129] The rear sealing cover 82 is located at the rear of the housing 10 and is positioned opposite the second cooling component 50B in the front-to-back direction. The rear sealing cover 82 can be tightly connected to the rear beam 113 by means of bolts, snap-fit, or riveting to maintain the sealing of the second cavity 1131.

[0130] The rear sealing cover 82 can be made of a material that is corrosion-resistant, high-temperature resistant and has good sealing performance, such as stainless steel, aluminum alloy or special plastic, to reduce the entry of liquid, dust or other contaminants into the second chamber 1131.

[0131] The battery provided in this application embodiment significantly improves the sealing performance of the battery case 10 by setting the front sealing cover 81 and the rear sealing cover 82, effectively reducing the entry of liquids, dust and other contaminants into the battery pack, achieving effective protection for the electrical equipment 30 and the cell assembly 20, thereby extending the battery's service life.

[0132] In some embodiments, such as Figure 6 and Figure 7 As shown, the electrical equipment 30 includes an electronic device 31 and a conductive busbar 32 that are electrically connected. A heat-conducting element 83 is provided between the second cooling device 50 and the electronic device 31 and / or between the second cooling device 50 and the conductive busbar 32.

[0133] Thermal conductive components 83 include, but are not limited to, thermal conductive adhesives, thermal conductive silicone pads, or thermal conductive grease, etc., and are not limited here.

[0134] In some embodiments, the thermal conductivity of the heat-conducting element 83 is 2W to 5W, and the thickness of the heat-conducting element 83 is 2mm to 10mm.

[0135] Specifically, the thermal conductivity of the heat-conducting component 83 can be 2W, 2.756W, 3W, 4.5W, 5W, or other values ​​between 2W and 5W, without any restrictions.

[0136] The thickness of the heat-conducting component 83 can be 2mm, 4.75mm, 6mm, 8.432mm, 10mm or other values ​​between 2mm and 10mm, and there are no restrictions here.

[0137] In the case where the electrical equipment 30 includes a battery circuit breaker unit 30A and a high-voltage power distribution unit 30B, the internal components of the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B are generally consistent. In other words, both the battery circuit breaker unit 30A and the high-voltage power distribution unit 30B include electrically connected electronic devices 31 and conductive busbars 32.

[0138] The electronic devices 31 include, but are not limited to, relays, fuses, or other devices. The busbar 32 is used to transmit electrical energy between these electronic devices 31 and between the electronic devices 31 and the battery pack 20.

[0139] In this embodiment, such as Figure 6 and Figure 7 As shown, heat-conducting components 83 are provided between the second cooling device 50 and the electronic device 31, and between the second cooling device 50 and the conductive busbar 32. Specifically, heat-conducting components 83 are provided between the electronic device 31 and the conductive busbar 32 of the battery circuit breaker unit 30A and the first cooling device 50A, and heat-conducting components 83 are provided between the electronic device 31 and the conductive busbar 32 of the high-voltage power distribution unit 30B and the second cooling device 50B.

[0140] In some other embodiments, a heat-conducting element 83 is provided between the second cooling device 50 and the electronic device 31.

[0141] In some other embodiments, a heat-conducting element 83 is provided between the second cooling device 50 and the conductive busbar 32.

[0142] The battery provided in this application embodiment, through the setting of the heat-conducting component 83, allows the heat generated by the electronic device 31 to be directly or indirectly transferred to the second cooling device 50 through the conductive busbar 32, which significantly improves the heat conduction efficiency between the electrical device 30 and the second cooling device 50, reduces thermal resistance, optimizes heat dissipation performance, and thus extends the service life of the electrical device 30.

[0143] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the second cooling device 50 is provided with a first outlet 51 and a second outlet 52. The first outlet 51 is used to avoid the high-voltage connector connected between the electrical equipment 30 and the battery cell assembly 20, and the second outlet 52 is used to avoid the low-voltage connector connected between the electrical equipment 30 and the battery cell assembly 20.

[0144] like Figure 1 , Figure 4 and Figure 5 As shown, when the electrical equipment 30 includes a battery circuit breaker unit 30A and a high-voltage power distribution unit 30B, both the first cooling element 50A and the second cooling element 50B are provided with a first outlet 51 and a second outlet 52.

[0145] The first outlet 51 on the first cooling element 50A is used to lead out a high-voltage connector connected between the battery circuit breaker unit 30A and the cell pack 20. This high-voltage connector is used to transmit high voltage and high current power between the battery circuit breaker unit 30A and the cell pack 20.

[0146] The first outlet 51 on the second cooling element 50B is used to lead out a high-voltage connector connected between the high-voltage power distribution unit 30B and the battery cell group 20. This high-voltage connector is used to transmit high-voltage and high-current power between the high-voltage power distribution unit 30B and the battery cell group 20.

[0147] The location, shape, and size of the first outlet 51 should be customized according to the specific layout and size of the high-voltage connector.

[0148] Multiple first outlets 51 can be provided. Multiple first outlets 51 are distributed at intervals and separated from the flow channel. Multiple means two or more.

[0149] For example, in some embodiments, such as Figure 4 and Figure 5 As shown, the first cooling component 50A has four first outlets 51, and the first cooling component 50A has five first outlets 51.

[0150] The second outlet 52 on the first cooling element 50A is used to lead out a low-voltage connector connected between the battery circuit breaker unit 30A and the cell pack 20. This low-voltage connector is used to transmit control signals or auxiliary power between the battery circuit breaker unit 30A and the cell pack 20.

[0151] The second outlet on the second cooling element 50B is used to lead out a low-voltage connector connected between the high-voltage power distribution unit 30B and the battery cell group 20. This low-voltage connector is used to transmit control signals or auxiliary power between the high-voltage power distribution unit 30B and the battery cell group 20.

[0152] The location, shape, and size of the second outlet 52 should be customized according to the specific layout and size of the low-voltage connector.

[0153] The battery provided in this application embodiment, by setting a first outlet 51 and a second outlet 52 in the second cooling device 50 as described above, realizes the transmission of high-voltage power and communication signals between the electrical equipment 30 and the cell group 20. Without affecting the flow channel of the first cooling device 40 itself, it makes it easier to connect and operate when maintaining or replacing high-voltage connectors and low-voltage connectors, reducing the complexity and time of maintenance.

[0154] In some embodiments, such as Figure 1 , Figure 8 and Figure 9 As shown, the housing 10 is provided with a first threaded structure 115 and a second threaded structure 116. The first threaded structure 115 and the second threaded structure 116 protrude from the inner sidewall of the electrical cavity 14. The second cooling device 50 is provided with a third threaded structure 53 for connecting with the first threaded structure 115. The electrical equipment 30 is provided with a fourth threaded structure 33 for connecting with the second threaded structure 116.

[0156] In this embodiment, such as Figure 8 and Figure 9As shown, both the first threaded structure 115 and the second threaded structure 116 can be brackets with threaded holes. The bracket can include a straight section and a sleeve section. The straight section can be connected to the inner wall of the first cavity 1111 or the second cavity 1131 and protrude inward relative to the inner wall of the first cavity 1111 or the second cavity 1131. The sleeve section can form a threaded hole. Both the front beam 111 and the rear beam 113 can each be provided with multiple first threaded structures 115 and multiple second threaded structures 116. At least some of the first threaded structures 115 and the second threaded structures 116 can be integrated into one unit. The third threaded structure 53 can be a threaded hole on the first cooling component 50A or the second cooling component 50B. A threaded connector can pass through and connect the first threaded structure 115 of the front beam 111 and the third threaded structure 53 of the first cooling component 50A to achieve the assembly of the first cooling component 50A on the front beam 111. A threaded connector can pass through and connect the first threaded structure 115 of the rear beam 113 and the third threaded structure 53 of the second cooling component 50B to achieve the assembly of the second cooling component 50B on the rear beam 113. The fourth threaded structure 33 can be a structure with a threaded hole. The lugs can protrude outward relative to the electronic components 31 of the battery circuit breaker unit 30A or the high-voltage power distribution unit 30B. The threaded connectors can pass through and connect the second threaded structure 116 of the front beam 111 and the fourth threaded structure 33 of the battery circuit breaker unit 30A to realize the assembly of the battery circuit breaker unit 30A in the first cavity 1111. The threaded connectors can pass through and connect the second threaded structure 116 of the rear beam 113 and the fourth threaded structure 33 of the high-voltage power distribution unit 30B to realize the assembly of the high-voltage power distribution unit 30B in the second cavity 1131.

[0157] The threaded connector can be, but is not limited to, screws or bolts, etc., and this application does not limit it.

[0158] The battery provided in this application embodiment, through the above-mentioned first thread structure 115, second thread structure 116, third thread structure 53 and fourth thread structure 33, realizes the assembly of the second cooling device 50 and electrical equipment 30 on the housing 10, reducing the risk of loosening and damage caused by vibration or impact. At the same time, since the threaded connection has the characteristics of easy installation and disassembly, the installation and maintenance of the second cooling device 50 and electrical equipment 30 are more convenient and quick, thereby improving the maintainability of the second cooling device 50 and electrical equipment 30.

At the same time, it also reduces the transfer of heat from the electrical equipment 30 to the cell assembly 20, alleviating the domino effect of thermal runaway of the cell assembly 20 caused by excessively high temperature of the electrical equipment 30. Furthermore, the second cooling device 50 replaces the original isolation structure on the housing 10, simplifying the structure of the housing 10, achieving overall miniaturization and lightweight design, while maintaining high volume utilization.
