In the current module bracket technology, the connection between the negative electrode of the battery cell and the module bracket is realized by positioning the battery cell through a circular hole, and the module bracket is composed of a series of circular holes. The round holes are formed by surrounding module bracket materials with certain wall thickness, and the holes are connected into a whole by the materials, so that the module bracket can be positioned to place the battery cell. Because the material that forms the hole has certain wall thickness, causes to have great clearance between two adjacent electric cores, so the whole module unit volume after the assembly is great, so under the module support of same volume, adopt the round hole volume density of uniting relatively low. In addition, the module bracket hole structure is relatively complex, and the dimensional accuracy and the assembly requirement are high. If the tolerance of the hole size is too large, although the cell assembly is convenient, the cell is not firmly fixed, and all the cells are possibly not on the same plane, so that the nickel strap welding effect is influenced; if the hole dimensional tolerance is too small, the battery core is difficult to assemble, and the battery core can not be inserted and cannot be welded seriously, so that the production efficiency is also influenced.
