Abstract

The invention discloses a detachable large module, which relates to the technical field of lithium batteries and comprises a bottom plate, a battery cell, a double-sided adhesive tape and an upper cover, the plurality of battery cells are arranged in a row; the double-sided adhesive tape is used for bonding the battery cells on the bottom plate, extends from one end of a row formed by the battery cells to the other end, and is provided with a non-viscous convex end at the end part of the row; and the upper cover covers the outer parts of the battery cells and is fixedly connected with the bottom plate. The battery pack has the advantages that the battery cell assembly is fixed through the double-sided adhesive tape, the risk that the battery cell assembly is loosened, displaced and even falls off in the use process of a large module in the battery pack can be prevented, the battery cells are simultaneously adhered to the bottom plate through the double-sided adhesive tape, and the double-sided adhesive tape is provided with the protruding end, so that the battery pack is convenient to disassemble.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a detachable large module. Background technique [0002] At present, the development of new energy power batteries is the general trend. Lithium batteries are moving towards higher energy density and integration. With the cost reduction of enterprises and the requirements of customers for battery pack space, it is imperative to improve the integration of battery packs. In the existing modules, the cells are generally fixedly connected to the casing by means of bolts or gluing, which is inconvenient to disassemble. The patent document with the publication number of CN111785883A discloses a battery module and an assembling method thereof. The battery module includes a cell assembly, and the two sides of the side plate of the cell assembly facing the casing are respectively bonded by a plurality of double-sided adhesive strips. On the inner surface of the board, the fixin...
