Abstract: The present disclosure relates to a composite end plate and a battery module. The composite end plate comprises a rigid substrate, which has a first surface and a second surface that are opposite in a thickness direction of the rigid substrate, the first surface is disposed facing batteries; a rigid connecting plate, which comprises a connecting portion and a hook portion that is bent toward the connecting portion, the hook portion is embedded in the rigid substrate to connect the rigid connecting plate to the rigid substrate, the connecting portion is located on the second surface for connecting and fixing with an external structural member, and a material of the rigid connecting plate is different from that of the rigid substrate. The composite end plate according to the present disclosure can improve the structural strength of the battery module.
