6. The fixing assembly according to claim 1 , wherein the limiting member is formed as a protrusion protruding from an outer surface of the end plate.
7. The fixing assembly according to claim 6 , wherein the protrusion is implemented as a plurality of protrusions arranged at intervals in an extending direction of the first binding tape.
8. The fixing assembly according to claim 1 , wherein the fixing member comprises:
a body disposed at a side of the end plate facing away from the battery module and engaged with the end plate; and
a connecting portion connected to the body and extending towards the battery module to be connected to the end of the battery module,
wherein when the fixing member and the first binding tape are mounted in place,
the first binding tape abuts against and is engaged with the body.
9. The fixing assembly according to claim 8 , wherein the connecting portion is implemented as a plurality of connecting portions arranged at intervals in a length direction of the body; and
each of the plurality of connecting portions is configured to be connected to one battery module or two adjacent battery modules.
10. The fixing assembly according to claim 8 , wherein the fixing member is an integrally formed piece.
11. The fixing assembly according to claim 8 , wherein the body is elongated, and the connecting portion is disposed on at least one end of the body.
12. The fixing assembly according to claim 8 , wherein the fixing member is implemented as two fixing members configured to connect two ends of the battery module respectively.
13. The fixing assembly according to claim 12 , further comprising a second binding tape configured to be disposed at an end away from an electrode of the battery module,
wherein the first binding tape is configured to be disposed at an end close to the electrode of the battery module.
14. The fixing assembly according to claim 13 , wherein:
at least a part of the second binding tape being disposed in the positioning area.
15. The fixing assembly according to claim 13 , wherein the first binding tape is made of a material same as or different from a material of the second binding tape.
16. A battery pack, comprising:
a plurality of battery modules; and
a fixing assembly comprising:
an end plate configured to cooperate with an outer side wall of the plurality of battery modules;
a fixing member cooperating with the end plate, a part of the fixing member extending to an upper end of the battery module that is a different end of the battery module from the outer side wall of the battery module, to be connected to the plurality of battery modules; and
a first binding tape wrapped around an outside of the plurality of battery modules and an outside of the end plate to bind the plurality of battery modules,
wherein when the fixing member and the first binding tape are mounted in place, the first binding tape abuts against and is engaged with at least a part of the fixing member,
wherein the fixing assembly further comprises:
a limiting member located on a side of the end plate facing away from the plurality of battery modules,
wherein a positioning area is defined by the limiting member, the fixing member and the end plate, at least a part of the first binding tape being disposed in the positioning area, wherein the fixing member, the first binding tape, and the limiting member are disposed together along a direction parallel to the end plate,
