Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0043] Figure 1 A schematic diagram of the structure of a battery module provided by an exemplary embodiment of the present application. Figure 2 A schematic diagram of a partial explosion of a battery module provided by an exemplary embodiment of the present application. Figure 3 A schematic diagram of the arrangement of the first module and the second module provided for an exemplary embodiment of the present application. Figure 4 for Figure 3 A magnified schematic diagram of center A. Figure 5 for Figure 3 The enlarged schematic diagram of point B in the figure. Figures 1 to 5 As shown, the battery module 100 provided in the embodiment of the present application may include a battery module 110 and a vertical plate 120, the battery module 110 includes a first end 111 and a second end 112 that are relatively arranged, the vertical plate 120 is arranged on one side of the first end 111, and a first cooling channel 130 is formed between the vertical plate 120 and the first end 111. After the air enters the first cooling channel 130, the first end 111 of the battery module 110 can be cooled.

[0044] The battery module 100 may further include a housing 140 , the housing 140 includes a top plate 141 and a side plate 142 , the side plate 142 is connected to the top plate 141 to form a cover 144 , and the cover 144 may cover the battery module 110 to protect the battery module 110 .

[0045] In one embodiment, there are two side panels 142 , and the two side panels 142 are respectively connected to two opposite sides of the top panel 141 . The two side panels 142 and the top panel 141 can form a U-shaped cover body 144 .

[0046] like Figure 5 As shown, the housing 140 may further include an end plate 143, which is disposed on one side of the second end 112, that is, the end plate 143 is disposed outside the second end plate 112, and the two opposite ends of the cover body 144 are respectively connected to the vertical plate 120 and the end plate 143 to cover the battery module 110, and a second cooling channel 150 may be formed between the end plate 143 and the second end 112, and after air enters the second cooling channel 150, the second end 112 of the battery module 110 may be cooled. Among them, the end plate 143 may also be integrally formed with the side plate 142 and the top plate 141, that is, the cover body 144 may include the top plate 141, the side plate 142 and the end plate 143, so as to simplify the structure and improve the convenience of installation.

[0047] like Figures 1 to 5 As shown, the side plate 142 is provided with a ventilation hole 1421, and the cover body 144 is covered on the battery module 110, and an air inlet channel 160 is formed between the side plate 142 and the side wall of the battery module 110. On the one hand, the air inlet channel 160 is connected with the ventilation hole 1421, and the external air can enter the air inlet channel 160 through the ventilation hole 1421, so that the air entering the air inlet channel 160 can cool the side wall of the battery module 110; on the other hand, the two ends of the air inlet channel 160 are respectively connected with the first cooling channel 130 and the second cooling channel 150, and the air entering the air inlet channel 160 from the ventilation hole 1421 can be diffused to the first cooling channel 130 and the second cooling channel 150, so that the air entering the first cooling channel 130 can cool the first end 111 of the battery module 110, and the air entering the second cooling channel 150 can cool the second end 112 of the battery module 110. That is to say, the battery module 100 provided in the embodiment of the present application can cool the side wall, the first end 111 and the second end 112 of the battery module 110, thereby achieving uniform cooling of different parts, reducing the temperature difference between different parts, and effectively extending the service life of the battery module 110.

[0048] like Figure 3 and Figure 5 As shown, the battery module 110 may include a first module 113 and a second module 114 , the first module 113 and the second module 114 are spaced apart, a main air duct 170 may be formed between the first module 113 and the second module 114 , and the main air duct 170 is connected to the second cooling channel 150 .

[0049] It should be understood that air can enter the main air duct 170 from the second cooling channel 150 (or enter the second cooling channel 150 from the main air duct 170), and the flowing air in the main air duct 170 can cool the other side wall of the first module 113 and the second module 114 away from the air inlet channel 160.

[0050] In one embodiment, a side of the first module 113 away from the main air duct 170 forms an air inlet channel 160 with one of the side panels 142; a side of the second module 114 away from the main air duct 170 forms another air inlet channel 160 with the other side panel 142; similarly, a first end 111 of the first module 113 can form a first cooling channel 130 with the vertical plate 120, and a first end 111 of the second module 114 can form another first cooling channel 130 with the vertical plate 120; similarly, a second end 112 of the first module 113 can form a second cooling channel 150 with the end plate 143, and a second end 112 of the second module 114 can form another second cooling channel 150 with the end plate 143.

[0051] It should be understood that the air flowing into the air inlet channel 160 and the main air duct 170 can cool the opposite side walls of the first module 113 and the second module 114, effectively reducing the temperature difference between different parts of the first module 113 and the second module 114, and achieving a more uniform cooling effect on the first module 113 and the second module 114.

[0052] Figure 6 This is a schematic diagram of the structure of a battery module without the outer shell provided by an exemplary embodiment of the present application. Figure 6 As shown, the battery module 100 may further include a fan 190 , which is mounted on the vertical plate 120 and is disposed toward the main air duct 170 .

[0053] In one embodiment, the fan 190 can draw air from the main air duct 170, so that the air outside the housing 140 can pass through the ventilation hole 1421 under the action of suction, and then enter the air inlet channel 160, and then enter the first cooling channel 130 and the second cooling channel 150 from the air inlet channel 160, and then enter the main air duct 170 from the second cooling channel 150, and then output the battery module 100 through the fan 190.

[0054] In one embodiment, the fan 190 can blow air toward the main air duct 170, and the air outside the battery module 100 can enter the main air duct 170 through the fan 190, and then enter the second cooling channel 150, and then enter the air inlet channel 160 and the first cooling channel 130, and then output the battery module 100 through the ventilation hole 1421.

[0055] It should be understood that after the fan 190 is started, the air flow rate can be increased, thereby improving the cooling rate of different parts of the battery module 110.

[0056] Figure 7 This is a schematic diagram of the structure of a fan, chassis, bracket and air duct frame provided by an exemplary embodiment of the present application. Figure 6 and Figure 7 As shown, the battery module 100 may also include a chassis 210, and the chassis 210 may include an outer frame 211 and a crossbeam 212, the crossbeam 212 is located inside the outer frame 211, and the two ends of the crossbeam 212 are respectively connected to the opposite side walls of the outer frame 211, the aforementioned vertical plate 120 is connected to the outer frame 211, and different parts of the fan 190 are respectively installed on the vertical plate 120 and the crossbeam 212.

[0057] It should be understood that, on the one hand, the cross beam 212 can enhance the overall structural strength of the outer frame 211 and facilitate the installation of the battery module 110; on the other hand, the cross beam 212 and the outer frame 211 can serve as installation carriers for the fan 190, which is beneficial to ensure the stability of the fan 190 after installation.

[0058] like Figure 6 and Figure 7 As shown, the battery module 100 may also include a bracket 220 and an air duct frame 230, the bracket 220 and the fan 190 are respectively located at opposite ends of the outer frame 211, the end of the outer frame 211 away from the fan 190 is connected to the bottom of the bracket 220, the air duct frame 230 is arranged above the main air duct 170, the air duct frame 230 is located between the bracket 220 and the fan 190, and the two ends of the air duct frame 230 are respectively connected to the top of the fan 190 and the top of the bracket 220.

[0059] It should be understood that the bracket 220 can be used as a mounting carrier of the duct frame 230 to facilitate the installation of the duct frame 230. The duct frame 230 is covered above the main duct 170, and the duct frame 230 can block the outflow of air in the main duct 170, so that the air flows along the main duct 170, ensuring the cooling effect of the air in the main duct 170 on the first module 113 and the second module 114.

[0060] Figure 8 A schematic diagram of the distribution of two adjacent first battery cells provided by an exemplary embodiment of the present application. Fig. 9 This is a schematic diagram of the structure of a battery module without the outer shell provided by another exemplary embodiment of the present application. Figure 8 and Fig. 9As shown, the first module 113 may include a plurality of first battery cells 1131 distributed side by side, a branch air duct 180 is formed between any two adjacent first battery cells 1131 , and the plurality of branch air ducts 180 are connected to the main air duct 170 and the air inlet channel 160 .

[0061] It should be understood that the air can enter the air inlet channel 160 from the main air duct 170 through the branch air duct 180, or enter the main air duct 170 from the air inlet channel 160. In this way, the air flowing in the branch air duct 180 can cool the side walls of two adjacent first battery cells 1131, thereby improving the heat dissipation efficiency of the multiple first battery cells 1131 and preventing the first battery cells 1131 from being overheated.

[0062] like Figure 8 As shown, a baffle 115 is provided between any two adjacent first battery cells 1131. It should be understood that the baffle 115 can be used to support two adjacent first battery cells 1131, and can limit the relative proximity of two adjacent first battery cells 1131, so as to ensure that the aforementioned branch air duct 180 can be formed between the two adjacent first battery cells 1131. Specifically, the baffle 115 can be arranged between two adjacent first battery cells 1131 at intervals along the height direction, and a branch air duct 180 arranged along the horizontal direction is formed between adjacent baffles 115, so as to facilitate air circulation.

[0063] Fig.10 The following is a schematic diagram of the distribution of two adjacent second battery cells provided by an exemplary embodiment of the present application. Fig.10 As shown, similar to the first module 113 , the second module 114 may include a plurality of second battery cells 1141 distributed side by side, a branch air duct 180 is formed between any two adjacent second battery cells 1141 , and the plurality of branch air ducts 180 are connected to the main air duct 170 and the air inlet channel 160 .

[0064] It should be understood that the air can enter the air inlet channel 160 from the main air duct 170 through the branch air duct 180, or enter the main air duct 170 from the air inlet channel 160. In this way, the air flowing in the branch air duct 180 can cool the side walls of two adjacent second battery cells 1141, thereby improving the heat dissipation efficiency of the multiple second battery cells 1141 and preventing the second battery cells 1141 from being overheated.

[0065] like Fig.10 As shown, similarly, a baffle 115 is provided between any two adjacent second battery cells 1141. It should be understood that the baffle 115 can be used to support two adjacent second battery cells 1141, and can limit the relative proximity of the two adjacent second battery cells 1141, so as to ensure that the aforementioned branch air duct 180 can be formed between the two adjacent second battery cells 1141.

[0066] Fig.11 FIG. 1 is a schematic diagram of a first module provided by an exemplary embodiment of the present application. Figure 3 , Fig. 9 as well as Fig.11 As shown, the battery module 100 may further include a first cover plate 240 , which is covered on the first module 113 , and the first cover plate 240 is provided with a first through channel 241 , which passes through the upper surface of the first module 113 , and the first through channel 241 connects the main air duct 170 and the air inlet channel 160 .

[0067] In actual application, the upper surface of the first module 113 is provided with a bus 116. During operation, a large current will flow through the bus 116, resulting in a large amount of heat being emitted. Under such operating conditions, the air in the air inlet channel 160 can flow into the main air duct 170 through the first through channel 241, or the air in the main air duct 170 can flow into the air inlet channel 160 through the first through channel 241. In this way, the ventilation capacity of the area above the first module 113 can be improved, and a large amount of heat generated by the bus 116 located above the module 113 during operation can be effectively taken away, thereby improving the problem that the bus 116 is prone to overheating.

[0068] In actual application, the applicant found that the temperature difference between the middle area of ​​the first module 113 and other areas is relatively large, and the temperature of this area is higher than that of other areas. Fig.11 As shown, the area penetrated by the first through channel 241 corresponds to the middle area of ​​the first module 113. In this way, the bus 116 in the middle area of ​​the first module 113 can be cooled to achieve rapid cooling, thereby reducing the temperature difference between the multiple first battery cells 1131 of the first module 113.

[0069] As mentioned above, since the cross-sectional area of ​​the second cooling channel 150 is larger than the cross-sectional area of ​​the branch air duct 180, the air can cool the end of the first module 113 close to the second cooling channel 150 after entering the second cooling channel 150, so that the working temperature of the end of the first module 113 close to the second cooling channel 150 is relatively low. To this end, a thermal insulation layer (not shown in the figure) can be provided on the surface of the multiple busbars 116 on the end of the first module 113 close to the second cooling channel 150 to reduce heat loss, improve the problem of large temperature difference between the first battery cells 1131 in different regions, and ensure that the first battery cells 1131 in different regions can all be in a better temperature range.

[0070] Fig.12 FIG. 1 is a schematic diagram of a second module 114 provided by an exemplary embodiment of the present application. Figure 3 , Fig. 9 as well as Fig.12As shown, the battery module 100 may further include a second cover plate 250 , which is covered on the second module 114 , and the second cover plate 250 is provided with a second through channel 251 , which passes through the upper surface of the second module 114 , and the second through channel 251 connects the main air duct 170 and the air inlet channel 160 .

[0071] In actual application, the upper surface of the second module 114 is provided with a bus 116. During operation, a large current will flow through the bus 116, resulting in a large amount of heat being emitted. Under such operating conditions, the air in the air inlet channel 160 can flow into the main air duct 170 through the second through channel 251, or the air in the main air duct 170 can flow into the air inlet channel 160 through the second through channel 251. In this way, the ventilation capacity of the area above the second module 114 can be improved, and a large amount of heat generated by the bus 116 during operation can be effectively taken away, thereby improving the problem that the bus 116 is prone to overheating.

[0072] In actual applications, the temperature difference between the middle area of ​​the second module 114 and other areas is relatively large, and the temperature of this area is higher than that of other areas. During operation, the temperature of the second battery cell 1141 in the middle area of ​​the second module 114 is likely to be too high. Fig.11 As shown, the area penetrated by the second through channel 251 corresponds to the middle area of ​​the second module 114. In this way, the bus 116 of the second battery cell 1141 in the middle area of ​​the second module 114 can dissipate heat to achieve rapid cooling, thereby reducing the temperature difference between the multiple second battery cells 1141 of the second module 114.

[0073] As mentioned above, after the air enters the second cooling channel 150, the end of the second module 114 close to the second cooling channel 150 can be cooled, so that the operating temperature of the multiple second battery cells 1141 at the end of the second module 114 close to the second cooling channel 150 is relatively low. To this end, a thermal insulation layer (not shown in the figure) can be provided on the surface of the multiple busbars 116 at the end of the second module 114 close to the second cooling channel 150 to reduce heat loss, improve the problem of large temperature difference between the second battery cells 1141 in different areas, and ensure that the second battery cells 1141 in different areas can all be in a better temperature range.

[0074] Fig.13 This is a temperature difference comparison table of different heat dissipation solutions provided by an exemplary embodiment of the present application. The temperature points are set at the same position of different battery cells.
