Abstract: The present disclosure provides a battery pack, including: battery modules, wherein two or more of the battery modules are arranged side by side in a first direction; and connecting assemblies, wherein each connecting assembly is connected between adjacent two battery modules, and the connecting assembly includes an elastic connecting member being able to elastically deform in the first direction such that the adjacent two battery modules are elastically connected by the connecting assembly. The elastic connecting member can provide a buffer between the adjacent two battery modules. In the case that one of the adjacent two battery modules suffers a force, the elastic connecting member can absorb a force from this battery module, to prevent the adjacent two battery modules from interacting with each other when suffering the force, and avoid a safety accident caused by the interaction between the two battery modules connected to each other.
