Problems solved by technology
[0004] Among the existing battery modules, there is no technically mature battery module. The battery module cannot take into account the optimization of volume, weight, heat dissipation performance, mechanical strength and the electrical performance of each single battery. The modularization of the battery has not yet been truly realized.

The invention discloses a battery module, comprising two trays, two or more series-parallel sheets, two current collectors and a plurality of single batteries, wherein the bottoms of the trays are uniformly provided with a plurality of block holes, a plurality of through holes are arranged among the block holes, the series-parallel sheets are fixedly arranged on the bottoms of the trays, the current collectors are fixedly arranged at the one side or two sides of the bottoms of the trays and are tightly connected with the series-parallel sheets through pressure plates, the two poles of the single batteries are respectively limited in the block holes arranged at the bottoms of the trays, and the two trays are connected with each other with relative fixing. The invention further discloses a battery module group, comprising two or more battery modules and a connection span bridge, wherein the connection span bridge connects the two or more connection span bridge. The battery module of the present invention has the advantages of small volume, light weight and good ventilation effectiveness, and the battery module group has strong adaptability, flexibility and stability.
Description
technical field [0001] The present invention relates to a battery module, in particular to a battery module with small volume, light weight, good ventilation effect and uniform confluence of individual cells; the present invention also relates to a battery module, in particular to a , flexible and stable battery module. It belongs to the technical field of battery modules. Background technique [0002] Compared with traditional cars, electric vehicles have obvious advantages in terms of environmental protection. Waste pollution and noise pollution are two major pollutions of internal combustion engine vehicles. Electric vehicles do not consume gasoline, have no exhaust pollution, low noise, and low radiation. They are ideal clean vehicles. With the enhancement of human's awareness of environmental protection, the application of electric vehicles is becoming more and more extensive, so the development of electric power battery packs for electric vehicles has become an impo...
