A battery module, a battery pack and an electric device

Abstract

The present application provides a battery module, a battery pack and an electric device, which relates to the technical field of power batteries. The battery module includes a box body and a plurality of battery cell assemblies arranged in the box body. The plurality of battery cell assemblies are arranged in a first direction. The battery cell assembly includes a battery and a mounting frame. The two mounting frames corresponding to two adjacent battery cell assemblies are connected by snap-fitting. The mounting frame includes a frame body and a connecting portion. The frame body has a mounting groove. At least part of the battery is mounted in the mounting groove. The two ends of the frame body along the second direction are respectively provided with corresponding connecting portions. At least part of the connecting portion protrudes from the frame body along the first direction. The two ends of the frame body of one mounting frame along the second direction are respectively abutted against the corresponding connecting portion of another adjacent mounting frame. The present invention further improves the installation stability of each battery cell on the basis of improving the assembly convenience and assembly efficiency of the plurality of battery cell assemblies.
