Abstract

The invention discloses a battery module. The battery module comprises a battery pack, an end plate, a side plate, an electric tray, a plurality of connecting plates and an upper cover. The battery pack is a cuboid and comprises a plurality of battery cells, and each battery cell comprises a pair of side surfaces, a pair of end surfaces, a bottom surface and a top surface. The battery cells abut against one other through the end surfaces to be arranged into the battery pack; two cover plates are arranged on the top surface of the battery cell, an electrode connecting end is arranged on each cover plate, and two sides of each electrode connecting end are depressed in opposite directions to form two notches. The electric tray is positioned above the battery pack for placing the connecting plates; each connecting plate comprises a main body part and two first connecting lugs formed through convexly extending from two sides of the main body part, and the two first connecting lugs of each connecting plate are matched with the two nearby notches on every two adjacent electrode connecting ends so as to realize electrical connection. According to the battery module, automatic production can be realized, the connecting plates are simple in structures, and assembly error is unlikely to appear.

Description

【Technical field】 [0001] The invention relates to the technical field of power batteries, in particular to a battery module. 【Background technique】 [0002] At present, the electric vehicle industry is developing rapidly, and people's demand for electric vehicles is also increasing. As one of the core components of new energy vehicles, the power battery has the characteristics of high safety, good cycle performance, environmental friendliness, non-toxic and harmless, and relatively low cost of raw materials, which has attracted people's attention. The large market demand for power batteries requires battery modules with a high degree of automation, small size, and high capacity density. The existing prismatic battery modules have complicated ways to lead out the positive and negative terminals, and the variety of materials makes it difficult to automate battery module assembly. [0003] In view of this, it is necessary to provide a new battery module to overcome the above ...
