Abstract

Disclosed is a battery module. The battery module comprises a plurality of single batteries, fixed frames, end plates, side plates, a mounting plate, current converging sheets and a protection cover, wherein the multiple single batteries are arranged in parallel; the fixed frames are arranged at the two ends of the single batteries at intervals; the end plates are arranged on one sides of the fixed frames at intervals; the edge of a second short side edge extends in a protruding manner to form a first welding part; the side plates are arranged on one sides of the single batteries respectively; a clamping part and the second welding part prop against the single batteries and the first welding part respectively; the mounting plate is arranged on the single batteries; clamping holes are formed in buckles in a sleeving manner; long current converging sheets and short current converging sheets are spliced and arranged on the mounting plate at intervals separately, and are electrically connected with the multiple single batteries; and the protection cover is arranged on the mounting plate. The battery module provided by the invention is simple in mounting structure, and capable of realizing mechanical automatic mounting, reducing the size of the battery module and improving energy density of the battery module.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of electric vehicles, in particular to a battery module. [0003] 【Background technique】 [0004] In the context of the energy crisis, the use of environmentally friendly energy is an inevitable choice for people's production and life. Lithium batteries have the characteristics of high safety, good circulation, no pollution, and relatively low cost of raw materials, and have been widely used in electric vehicles. Lithium batteries are widely used in today's power battery systems, and are widely used in passenger cars, commercial vehicles, and logistics vehicles. With the increasing demand for lithium batteries in the market today and the continuous development of lithium battery technology, lithium batteries are modular in groups, small in size, and high energy density. However, the existing lithium batteries mostly use angle steel riveting and plastic frame to form the battery module, but the assembled ...
