[0069] Further, preferably, the heating film 26 is an electric heating film 26. Correspondingly, a wiring opening 234 is formed at the top of the U-shaped pressing plate 23 for the wiring of the heating film 26.

[0070] In this embodiment, preferably, as Figure 3 and Figure 5 shown, the battery module 2 further includes a fixing band 27, and the battery cell assembly 21, the U-shaped pressing plate 23, and the insulating plate 25 are fixed via the fixing band 27. And preferably, the fixing band 27 is wound around the outer periphery from the top to the bottom.

[0071] According to the structure described above, the fixing band 27 will reinforce and fix the battery cell assembly 21, the U-shaped pressing plate 23, and the insulating plate 25 together.

[0073] In this embodiment, preferably, a foam is provided between any two adjacent lithium battery cells 211 for flame retardancy and heat insulation.

[0074] In this embodiment, preferably, as Figure 4 and Figure 5 shown, the battery module 2 further includes six connection rows 28. Three connection rows 28 are respectively provided at both ends of the battery cell assembly 21 along the direction perpendicular to the preset direction. The number of lithium battery cells 211 is eight, and it is necessary to ensure that the positive and negative electrodes at both ends of the eight battery cells are alternately arranged. The eight lithium battery cells 211 are connected in series through the six connection rows 28 at both ends. Preferably, along the preset direction, for this row of battery cells, that is, the left end of the battery cell assembly 21, except for the two outermost battery cells, for the six middle battery cells, the positive and negative electrode posts of any two adjacent battery cells are electrically connected through the connection row 28. Similarly, for the right end of this row of battery cells, the positive and negative electrode tabs are also connected in the same way as the left side;

[0075] For the same end of the two outermost lithium battery cells 211, for example, one at the left end is used as the positive output terminal and one as the negative output terminal.

[0076] It should be noted that: the number of lithium battery cells 211 and the number of connection rows 28 are not limited to the above. For example, the number of lithium battery cells 211 can also be less than eight, such as four, five or six, etc., or the number of lithium battery cells 211 can also be greater than eight, such as nine, ten or eleven, etc. And correspondingly, the number of connection rows 28 is adjusted. Especially when the number of lithium battery cells 211 is an even number, the positive output terminal and the negative output terminal are led out at the same end of the battery cell assembly 21 along the preset direction. For example, in this embodiment, it is led out from the left end. Of course, it is not limited to this, and it can also be led out from the right end, which is specifically designed according to actual needs to simplify the lead-out structure and help reduce production costs; when the number of lithium battery cells 211 is an odd number, although the positive and negative are still led out from the two outermost battery cells of the battery cell assembly 21, at this time, the positive output terminal and the negative output terminal are respectively located at both ends of the battery cell assembly 21 along the preset direction, that is, led out from the left end and the right end respectively, which is specifically designed according to actual needs.

[0080] Further, preferably, the two insulating fixing seats 3 are respectively disposed on both sides of the top of the U-shaped pressing plate 23 along a preset direction, so that the positive output row 4 and the negative output row 5 are respectively located on both sides, and are correspondingly connected to the positive output pole columns and negative output pole columns of the two battery cells on both sides. Of course, the two insulating fixing seats 3 need to be determined according to the positive output end and the negative output end of the battery cell assembly 21. When the positive and negative output ends are respectively located at both ends of the battery cell assembly 21 along the preset direction, that is, its length direction, the two insulating fixing seats 3 are also disposed at both ends of the top of the U-shaped pressing plate 23 along a direction perpendicular to the preset direction, and are specifically designed according to actual needs.
