Battery module

1. A battery module, comprising:

two or more battery cells, each comprising an electrode terminal;

a connecting member, wherein the electrode terminals of adjacent battery cells are connected by the connecting member; and

a clamping-sampling member, comprising a wire connection portion for fixing a wire harness and a clamping portion, wherein one end of the clamping portion is connected with the wire connection portion and another end of the clamping portion clamps the connecting member,

wherein a sampling installation portion is provided on a side of the connecting member facing the wire harness, and the clamping portion clamps the sampling installation portion,

the sampling installation portion extends from the side of the connecting member facing the wire harness and is recessed towards a battery top cover, so that the clamping-sampling member is attached directly to the battery top cover when clamping the sampling installation portion.

2. The battery module according to claim 1 , wherein the clamping portion comprises a first clamping part and a second clamping part, one end of the first clamping part is fixedly connected with one end of the second clamping part, while another end of the first clamping part and another end of the second clamping part form an opening of the clamping portion, and the one ends of the first clamping part and the second clamping part fixedly connected to each other are connected with the wire connection portion.

3. The battery module according to claim 2 , wherein the first clamping part and the second clamping part are integrally formed.

4. The battery module according to claim 2 , wherein the first clamping part and the second clamping part are independently formed;

the first clamping part is provided with a holding part for holding the second clamping part, or the second clamping part is provided with a holding part for holding the first clamping part,

wherein the holding part for holding the second clamping part or the holding part for holding the first clamping part is located at the one ends of the first clamping part and the second clamping part fixedly connected to each other.

5. The battery module according to claim 4 , wherein the holding part for holding the second clamping part or the holding part for holding the first clamping part comprises two side wings respectively connected to two sides of the first clamping part or the second clamping part, each side wing is formed in a shape of “L” and comprises a first arm and a second arm, the second arm is connected to the first clamping part or the second clamping part via the first arm, and the second arms of the two side wings are formed to extend towards each other.

6. The battery module according to claim 2 , wherein the first clamping part and the second clamping part form a guide opening which flares outwards at an end of the opening.

7. The battery module according to claim 2 , wherein the first clamping part is provided with a protrusion on a side surface of the opening facing the second clamping part, or the second clamping part is provided with a protrusion on a side surface of the opening facing the first clamping part; and

the sampling installation portion is provided with a connection hole, and the protrusion is matched with the connection hole.

8. The battery module according to claim 5 , wherein there are two or more connection holes.

9. The battery module according to claim 5 , wherein the sampling installation portion is further provided with a guide slot extending from an end of the sampling installation portion towards an inside of the connecting member, so that the protrusion on the first clamping part or the second clamping part can slide along the guide slot.

10. The battery module according to claim 1 , wherein the wire connection portion has a U-shaped cross section, so that the wire harness is installed within the wire connection portion.
