The disclosure relates to a fixing band for a battery module and a battery module. The fixing band comprises a first end portion, a connecting section and a second end portion which are arranged successively in an extending direction of the fixing band. The first end portion includes a body and engaging grooves which are protruded in a thickness direction of the body. The engaging grooves are integral with the body. The second end portion has engaging protrusions which are shaped to match the engaging grooves. The first end portion and the second end portion are laminated in the thickness direction and are engaged with each other by the engaging grooves and the engaging protrusions, so that the fixing band encloses an annular accommodation space.

Fixing band for battery module and battery module

The disclosure relates to an end plate and a battery module. The end plate comprises an end plate body, which has an inner surface and an outer surface that are opposed in a thickness direction of the end plate body, the outer surface is engaged with a fixing band for the battery module; and a limiting assembly, which is disposed on the outer surface, the limiting assembly includes a fixed clamping member and a movable clamping member which are spaced apart from each other in a height direction of the end plate body and are used in cooperation with each other. A clamping space is formed between the fixed clamping member and the movable clamping member. The movable clamping member can make room for the fixing band so that the fixing band enters the clamping space by the movable clamping member and is limited within the clamping space.
