Non-modular type battery box for square electric forklift electric cores and power battery pack

Abstract

The invention relates to the technical field of power batteries, in particular to a non-modular type battery box for square electric forklift electric cores and a power battery pack. The non-modular type battery box for the square electric forklift electric cores comprises a box body, wherein a battery containing cavity is formed in the box body, and a plurality of limiting supporting frames are vertically arranged on a base plate of the box body at intervals; the battery containing cavity is divided into a plurality of electric core plug-in mounting cavities by the limiting supporting frames,and the electric core plug-in mounting cavities are used for mounting the electric cores in a plug-in counterpoint mode; and a cover plate is mounted at the upper end of the box body. According to the non-modular type battery box for the square electric forklift electric cores and the power battery pack, when mounting is carried out, the square electric forklift electric cores are inserted in theelectric core plug-in mounting cavities in a counterpoint mode and are fixed, the electric cores do not need to be fixed into a battery module in advance, and the binding step is omitted; and the limiting of the electric cores in the Z direction is realized, the square electric forklift electric cores are limited on the side edges, the corresponding positions of the square electric forklift electric cores in the electric core plug-in mounting cavities are effectively limited, the overturning and skewing of the square electric forklift electric cores are prevented, and the technical problem that an existing square electric forklift electric core needs to be fixed into a module and then assembled into the box body in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a moduleless battery box and a power battery pack for square electric forklift batteries. Background technique [0002] In electric forklifts, the common battery packs at this stage are all square, which are generally fixed into a battery module by several cells with a square cross section (referred to as square cells), and then multiple battery modules are fixed into the box Make layout connections. [0003] The fixation between the square cells of each battery module is mostly fixed by the peripheral frame, or the adhesive materials such as glue are used to fix the square cells through pressure; the battery module fixed by the square cells is then fixed to the box. In the body; each square battery cell in the battery pack relies on the box or the fixed frame inside the box to realize the fixation in the X and Y horizontal directions, and relies on the glue between the ...

Problems solved by technology

[0004] In the method of bonding with glue, the glue coating efficiency of the square cell is low, the overall operation convenience is not good, and the cost is high, and because the directional cell will heat up when it is working, the glue will fail under the action of heat for a long time; and The mold opening cost of the peripheral plastic frame with the peripheral frame fixing method is relatively high, and there are many types of electric forklifts, which leads to repeated mold opening and further increases in cost

[0005] Especially when the weight of the square cell increases, or the amount of glue needs to be increased, or stronger glue is needed, or the mold needs to be re-opened, this will lead to a further increase in costs; especially when
