[0041] As described in the background technology, the battery module of the related technology includes a frame and multiple cylindrical batteries, the frame includes a bottom plate, and the multiple cylindrical batteries are arranged in multiple groups along the height direction of the frame. When the multiple cylindrical batteries at the bottom layer need to be fixed in the frame, it is necessary to use an adhesive to bond the multiple cylindrical batteries at the bottom layer so that the multiple cylindrical batteries are fixed in the frame.

[0042] However, the fixing method of directly bonding the multiple cylindrical batteries to the bottom plate by using an adhesive reduces the fixing strength of the multiple cylindrical batteries at the bottom layer.

[0043] In response to the above technical problems, the embodiments of the present application provide a battery module and a vehicle, which increase the spacing between the multiple batteries in the lowest battery cell layer and the bottom plate by adopting the setting of mounting strips, and increase the thickness of the adhesive by fixing the multiple batteries in the lowest battery cell layer to the mounting strips and the bottom plate through adhesives, thereby improving the fixing strength between the multiple batteries in the lowest battery cell layer and the bottom plate; by adopting the setting of serpentine plates, the multiple batteries in adjacent battery cell layers can be respectively fixed in the first trough body and the second trough body, and the serpentine plate is fixed to the bottom plate of the frame through a fixing plate, so that the multiple batteries can be indirectly fixed to the bottom plate, thereby further improving the fixing strength of the multiple batteries fixed in the frame; by clamping the connector of the copper plate with the mounting port on the serpentine plate, the copper plate can be fixed on the serpentine plate, thereby improving the fixing strength of the copper busbar fixed in the frame.

[0047] Combination Figures 3 to 7 Each group of battery cell units 200 includes multiple battery cell layers 210, and each group of battery cell layers 210 includes multiple batteries 211. The mounting member 300 includes at least two mounting bars 320. The mounting bars 320 are arranged between the multiple batteries 211 of the lowest battery cell layer 210 and the bottom plate 110, and the mounting bars 320 are arranged along the length direction of the multiple batteries 211 of the battery cell layer 210.

[0055] In this embodiment, the axis of the cylindrical battery is perpendicular to the length direction of the mounting strip 320; thirteen first slots 420 are provided, and the thirteen first slots 420 correspond one-to-one to the thirteen batteries 211 of the upper battery core layer 210; thirteen second slots 430 are provided, and the thirteen second slots 430 correspond one-to-one to the thirteen batteries 211 of the lower battery core layer 210; the first slot 420 is arranged in an arc shape, and the second slot 430 is arranged in an arc shape, and the arc-shaped first slot 420 and second slot 430 are arranged in coordination with the cylindrical battery; the battery 211 is fixed in the first slot 420 and the second slot 430 by gluing; in other embodiments, the battery 211 can be replaced with a rectangular battery, and the first slot 420 and the second slot 430 are arranged in coordination with the rectangular battery 211.

[0056] By adopting the above technical solution and the setting of cylindrical batteries, the cylindrical batteries have good thermal diffusion effect, high production consistency and higher safety; by adopting the setting of the serpentine plate 410, the first trough body 420 and the second trough body 430, when the battery 211 is fixed in the first trough body 420 and the second trough body 430, the contact area between the battery 211 and the serpentine plate 410 is increased, thereby improving the fixing strength between the battery 211 and the serpentine plate 410; by coordinating the first trough body 420 and the second trough body 430 with the cylindrical batteries, the space occupied by adjacent battery core layers 210 and the serpentine plate 410 is reduced, thereby reducing the space occupied by the entire battery module and reducing the installation space of the battery module installed on the vehicle body.

[0057] Combination Figures 3 to 7 In this embodiment, the cylindrical battery has a positive electrode 212 and a negative electrode 213, and the positive electrode 212 and the negative electrode 213 are arranged at the same end of the cylindrical battery. An explosion-proof valve 214 is provided at the end where the positive electrode 212 and the negative electrode 213 of the cylindrical battery are located; by arranging the positive electrode 212 and the negative electrode 213 of the cylindrical battery at the same end of the battery 211, it is convenient to electrically connect multiple batteries 211.

[0058] Combination Figures 3 to 7 A refrigerant channel is arranged inside the serpentine plate 410, and a liquid inlet end and a liquid outlet end are arranged on the serpentine plate 410. The liquid inlet end is connected to one end of the refrigerant channel, and the liquid outlet end is connected to the other end of the refrigerant channel.

[0059] In this embodiment, the liquid inlet and the liquid outlet are arranged at the two ends of the serpentine plate 410, or the liquid inlet and the liquid outlet can be arranged at the same end of the serpentine plate 410. The refrigerant channel inside the serpentine plate 410 is distributed in a serpentine shape, thereby increasing the cooling area of ​​the serpentine plate 410 and improving the cooling efficiency of the serpentine plate 410 on the battery 211.

[0060] By adopting the above technical solution, by adopting the settings of the refrigerant channel, the liquid inlet end and the liquid outlet end, by inputting the refrigerant from the liquid inlet end, the refrigerant can flow in the refrigerant channel, so that the serpentine plate 410 cools the multiple batteries 211 in the first trough body 420 and the second trough body 430 through the refrigerant in the refrigerant channel. Because the first trough body 420 and the second trough body 430 cooperate with the cylindrical battery, the contact area between the serpentine plate 410 and the battery 211 is increased, which indirectly improves the cooling efficiency of the serpentine plate 410 for the multiple batteries 211. The refrigerant after cooling the battery 211 can be discharged along the liquid outlet end, thereby facilitating the delivery of new refrigerant to the serpentine plate 410; by cooling the battery 211, it helps to reduce the capacity decay of the battery 211 and extend the service life of the battery 211.

When the battery 211 is fixed on the serpentine plate 410, the multi-layer battery cell layers 210 except the lowest battery cell layer 210 can be indirectly fixed on the base plate 110, thereby further improving the fixing strength of the multi-layer battery cell layers 210; by setting the fixing members 500 at both ends of the serpentine plate 410, the fixing strength between the serpentine plate 410 and the base plate 110 is improved, thereby further improving the fixing strength of the multiple batteries 211 fixed in the frame 100.

[0063] Combination Figures 3 to 7 The fixing member 500 includes a fixing plate 510 , one side of the fixing plate 510 is connected to the connecting member 400 , and the other side is disposed on the bottom plate 110 .

[0065] By adopting the above-mentioned technical solution and the setting of the fixed plate 510, the fixed plate 510 has a simple structure and is easy to produce, thereby improving the production efficiency of the serpentine plate 410 and the fixed plate 510; by fixing the fixed plate 510 on the serpentine plate 410 and the base plate 110, the fixing strength of the serpentine plate 410 is improved.

[0066] Combination Figures 3 to 7 In this embodiment, a waist-shaped hole 513 is opened on the second plate body 512 and located at the position where the bolt is passed through.
