Abstract

The present invention relates to a battery module, which comprises battery monomer arrangement structures, a first cover body and a second cover body, wherein the first cover body is connected to thesecond cover body, the battery monomer arrangement structures are arranged between the first cover body and the second cover body, the first cover body comprises a first bearing part and a second bearing part, the first bearing part and the second bearing part are of a split structure, the battery module comprises more than two battery monomer arrangement structures, the first battery monomer arrangement structure is arranged opposite to the first bearing part, and the second battery monomer arrangement structure is arranged opposite to the second bearing part. Different from the prior art, the battery module of the invention is transferred by utilizing the first cover body, and other parts do not need to be additionally added, so that the energy density of the battery module is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module and a battery pack. Background technique [0002] Secondary batteries have the advantages of high energy density, long service life, energy saving and environmental protection, and are widely used in different fields such as new energy vehicles and energy storage power stations. [0003] The battery module includes a battery cell arrangement structure, a bus bar, an upper cover and a lower cover. The battery cell arrangement structure includes a plurality of battery cells and a plurality of bus bars electrically connecting the plurality of battery cells. The battery cell arrangement structure is accommodated in Inside the chamber enclosed by the upper cover and the lower cover. When assembling a battery module, if multiple battery cells are first fixed and connected to multiple bus bars to form a battery cell arrangement structure, and then the battery cell ar...
