The plurality of wind power generation modules 30 can be divided into at least two parts. One part of the wind power generation modules 30 is arranged on the first end beam 211 or at a position of the box body 20 close to the first end beam 211 and arranged along the length direction of the first end beam 211, and the other part of the wind power generation modules 30 is arranged on the second end beam 212 or at a position of the box body 20 close to the second end beam 212 and arranged along the length direction of the second end beam 212.

[0096] By adopting the above technical solution, the end-side space of the battery device 100 can be fully utilized, thereby further reducing the risk of interference between the wind power generation module 30 and other components of the battery device 100.

[0097] In some embodiments of the present application, please refer to Figure 2 and Figure 4 as well. The box body 20 further includes a first mounting beam 22 and a second mounting beam 23. The first mounting beam 22 and the second mounting beam 23 are respectively arranged on opposite sides of the frame body 21 and are both used to connect an external support structure. An air duct 25 is formed inside the first mounting beam 22 and / or inside the second mounting beam 23, and at least one wind power generation module 30 is arranged in the air duct 25.

[0098] The first mounting beam 22 and the second mounting beam 23 are both components for fixing the battery device 100 to an external support structure. For example, the first mounting beam 22 and the second mounting beam 23 can be fixedly connected to the chassis of the vehicle 1000 to fix the battery device 100 to the chassis of the vehicle 1000. An air duct 25 can be formed only inside the first mounting beam 22, or only inside the second mounting beam 23, or air ducts 25 can be formed both inside the first mounting beam 22 and inside the second mounting beam 23. Understandably, when the air duct 25 is formed inside the first mounting beam 22, the air duct 25 of the first mounting beam 22 communicates with the external environment of the box body 20 so that external air flow can enter the air duct 25 of the first mounting beam 22. One wind power generation module 30 can be arranged inside the air duct 25 of the first mounting beam 22, or multiple wind power generation modules 30 can be arranged inside the air duct 25 of the first mounting beam 22; when the air duct 25 is formed inside the second mounting beam 23, the air duct 25 of the second mounting beam 23 communicates with the external environment of the box body 20 so that external air flow can enter the air duct 25 of the second mounting beam 23. One wind power generation module 30 can be arranged inside the air duct 25 of the second mounting beam 23, or multiple wind power generation modules 30 can be arranged inside the air duct 25 of the second mounting beam 23.

[0099] In some embodiments, the first mounting beam 22 is a profile, and the cavity of the first mounting beam 22 constitutes the air duct 25.

[0102] By adopting the above technical solutions, not only can the wind power generation module 30 generate electricity more effectively using wind energy, but also the internal space of the first mounting beam 22 and / or the internal space of the second mounting beam 23 can be fully utilized, thereby further reducing the risk of interference between the wind power generation module 30 and other components of the battery device 100.

[0103] In some embodiments of the present application, please refer to Figure 2 , the battery device 100 further includes a plurality of first power transmission lines 40.

The plurality of first power transmission lines 40 are all fixed inside the frame 21.

[0104] The first power transmission line 40 is a component for transmitting the electric energy generated by the wind power generation module 30 to the battery cell 10. The connection of multiple first power transmission lines 40 to multiple wind power generation modules 30 in a one-to-one correspondence means that each wind power generation module 30 is electrically connected to the battery cell 10 through a first power transmission line 40. The inner side of the frame 21 refers to the side of the frame 21 facing the battery cell 10, which can be the side of the first side beam 213 facing the battery cell 10, or the side of the second side beam 214 facing the battery cell 10, or the side of the first end beam 211 facing the battery cell 10, or the side of the second end beam 212 facing the battery cell 10.

[0105] In some embodiments, multiple first power transmission lines 40 can be bundled together to form a wire harness, and the wire harness is fixed to the inner side of the frame 21.

[0106] In some embodiments, the housing 20 further includes a buckle member, which is fixed to the inner side of the frame 21 and is used to buckle and fix the first power transmission line 40.

[0107] By adopting the above technical solution, the wiring structure between the wind power generation module 30 and the battery cell 10 is optimized, which not only improves the utilization rate of the internal space of the battery device 100, but also can effectively reduce the risk of interference between the first power transmission line 40 and other components of the battery device 100.

In some embodiments, the battery device 100 includes a plurality of battery cells 10, and the plurality of battery cells 10 are connected in series or in parallel or in series-parallel to form a battery cell assembly, and the high-voltage connector 50 is electrically connected to the battery cell assembly.

[0112] In some embodiments, the battery device 100 includes a first power transmission line 40. The wind power generation module 30 and the high-voltage connector 50 are electrically connected through the first power transmission line 40 to input the electric energy generated by the wind power generation module 30 into the battery cell 10.

[0113] In some embodiments, the battery device 100 includes a second power transmission line. The wireless charging module 60 and the high-voltage connector 50 are electrically connected through the second power transmission line to input the electric energy generated by the wireless charging module 60 into the battery cell 10.

[0114] By adopting the above technical solutions, it is convenient to electrically connect the wind power generation module 30 and the wireless charging module 60 to the battery cell 10.

[0115] In some embodiments of the present application, please refer to Figures 4 to 6 together, the wireless charging module 60 is disposed on the bottom guard plate 24.

[0116] It can be understood that the bottom guard plate 24 is connected to the bottom of the frame body 21. The bottom guard plate 24 is used to isolate the internal environment of the battery device 100 from the external environment and also serves as a protective device for the battery cell 10.

[0117] In some embodiments, the wireless charging device has a plate-like structure, and the wireless charging device is attached to the bottom guard plate 24. The wireless charging device can be attached to the surface of the bottom guard plate 24 facing the battery cell 10, or can be attached to the surface of the bottom guard plate 24 facing away from the battery cell 10, or can also be attached to the inside of the bottom guard plate 24.

[0118] By adopting the above technical solutions, the distance between the wireless charging module 60 and the wireless charging device can be effectively shortened, the magnetic loss between the wireless charging module 60 and the wireless charging device can be effectively reduced, and thus the charging efficiency of the wireless charging module 60 is effectively improved.

[0119] In some embodiments of the present application, please refer to Figure 5 and Figure 6 together, an installation cavity 241 is formed inside the bottom guard plate 24, and the wireless charging module 60 is disposed in the installation cavity 241.

[0120] In some embodiments, the bottom guard plate 24 is a profile, and the cavity of the bottom guard plate 24 constitutes the above-mentioned installation cavity 241.

[0121] In some embodiments, the bottom guard plate 24 is provided with a plurality of reinforcing ribs in the installation cavity 241. The plurality of reinforcing ribs divide the installation cavity 241 into a plurality of cavities. The number of the wireless charging modules 60 is multiple, and the multiple wireless charging modules 60 are all electrically connected to the battery cell 10. The multiple wireless charging modules 60 are arranged in one-to-one correspondence with the multiple cavities.
