In the battery module provided in this embodiment, the battery 1 is electrically connected to the main control board 3 by the elastic conduction sheet 2 so that conduction between the battery 1 and a circuit of the main control board 3 is achieved. One end of the elastic conduction sheet 2 is welded to the battery 1 and another end of the elastic conduction sheet 2 is welded to the main control board 3 so that two ends of the elastic conduction sheet 2 are connected by welding, thereby eliminating the use of tin and effectively reducing the material costs. Moreover, when the battery 1, the main control board 3, and the elastic conduction sheet 2 have position errors or thermal expansion, the elastic conduction sheet 2 can be elastically deformed adaptively, thereby ensuring the connection firmness of contact points. Additionally, since the ends of the elastic conduction sheet 2 are convenient to position, the welding with the battery 1 and the main control board 3 may be performed through automation equipment, thereby improving the productive efficiency. Therefore, the battery module proposed in this embodiment can reduce the material costs and can be manufactured using automation equipment, thereby increasing the productive efficiency.
In an embodiment of the present disclosure two elastic conduction sheets 2 are provided. Two ends of one elastic conduction sheet 2 are welded to the positive electrode of the battery 1 and the positive electrode of the main control board 3 respectively.

In an embodiment of the present disclosure, the elastic fastening member 8 includes a baseplate 81 and two side plates 82. The baseplate 81 and the two side plates 82 are connected to form a U-shaped structure and the two side plates 82 are connected to the main control board 3 and are each provided with an elastic clamping plate 821. The tail of the spring contact terminal 9 is inserted in the U-shaped slot of the U-shaped structure and clamped by two elastic clamping plates 821 of the two side plates 82. Since the baseplate 81 and the two side plates 82 are connected to form a U-shaped structure and the two elastic clamping plates 821 elastically clamps the spring contact terminal, the position of the tail of the spring contact terminal 9 is accordingly limited.
In an embodiment of the present disclosure, the ends of the side plates 82 are inserted into the main control board 3 and welded to the main control board 3 so that the connection firmness is ensured, the tin is eliminated, and the costs are saved.
In an embodiment of the present disclosure, one end of an elastic clamping plate 821 is connected to the inner wall of a side plate 82 and another end of the elastic clamping plate 821 is a free end. The free end extends obliquely toward the inside of the elastic fastening member 8. When the tail of the spring contact terminal 9 is inserted into the elastic fastening member 8 and abuts the free ends of two elastic clamping plates 821, the free ends of the two elastic clamping plates 821 face away from each other and are elastically deformed. The two elastic clamping plates 821 clamp the tail of the spring contact terminal 9 under the action of the elastic restoring force.
In an embodiment of the present disclosure, a side plate 82 is provided with a bypass slot 822. One end of an elastic clamping plate 821 is connected to the inner wall of the bypass slot 822 and another end of the elastic clamping plate 821 is a free end. The free end extends obliquely toward the inside of the elastic fastening member 8, extends out of the bypass slot 822, and enters the U-shaped slot of the elastic fastening member 8 to abut the tail of the spring contact terminal 9. The tail of the spring contact terminal 9 is clamped by two elastic clamping plates 821 of the two side plates 82. In this structure, when manufactured, a part of the side plate 82 can be cut, and the part is bent inwardly to form an elastic clamping plate 821. The exposed through slot is a bypass slot 822. This structure is convenient to manufacture and saves materials. The existence of the bypass slot 822 makes large the elastic deformation range of the elastic clamping plate 821.
In an embodiment of the present disclosure, the ends of the side plates 82 and the baseplate 81 facing the head of the spring contact terminal 9 are bent toward the side facing away from each other to form lead-in flanges 823. The lead-in flanges 823 play a guiding role to facilitate the insertion of the tail of the spring contact terminal 9.
