Abstract: The present application relates to a battery module. A battery module includes a base, end plates, side plates and a plurality of sleeve members, wherein the end plates and the side plates are connected to the base through the sleeve members, and each sleeve member includes a pipe body and a connecting piece. The battery module further includes a transition piece having a transition plane perpendicular to the axis of the pipe body. The connecting piece has a mating surface toward the transition piece, and the mating surface clings to the transition plane. This solution enables the connecting piece to be screwed into the base along the axis of the pipe body, reducing the difficulty of connecting the connecting piece to the base, and improving the installation efficiency.
