Embodiment Construction

[0028] Such as Figure 1 to Figure 6 As shown, the cylindrical power battery module structure of the present invention includes at least two battery modules 100 connected in series. The battery module 100 includes:

[0029] The battery pack includes cylindrical batteries 5 of the same type arranged in parallel and at intervals. Usually, the same electrodes of each battery 5 of each battery pack are located on the same side, and the batteries in the battery pack can also be divided into two groups, three groups, etc. according to needs, and the same electrodes of the batteries in each group are located on the same side , Different groups of batteries can be located on the same side or on different sides as needed.

[0030] Cell support 4. The two cell holders 4 are located on both sides of the electrodes of the cell group to clamp the cell group and connect and fix it. The opposite side of the battery support 4 (that is, the inner side of the battery support) includes the b...

Abstract

A cylindrical power battery module structure, including at least two battery modules connected in series, the battery module includes a battery pack, a battery support, a positive nickel sheet and a negative nickel sheet, a circuit board, and the battery module structure includes a nickel sheet Connect the rigid pressure plate, nickel sheet connection bolts and nuts, module connection bolts, nuts and supports, cell bracket, battery pack, positive nickel sheet and negative electrode nickel sheet to assemble a battery module, and the battery module is connected to the rigid pressure plate and nickel sheet through nickel sheets The bolts, the nickel sheet connection nuts, the module connection bolts, the module connection nuts and the support are connected to form a battery module. The nickel sheets between the battery modules of the present invention are connected by rigid pressure plates with multi-point bolts, and the nickel sheets between the modules are directly and tightly connected with equal pressure to ensure that the total internal resistance of the modules is small, the self-consumption is low, and the electrical connection reliability is high; the positive side of the battery module is connected to the The structure of the negative electrode side corresponds to each other, which is easy to expand the capacity of the battery module. The battery module structure is easy to standardize design, which is beneficial to realize large-scale production and reduce manufacturing costs.

Description

technical field [0001] The invention relates to a battery structure, in particular to a cylindrical power battery module structure. Background technique [0002] Energy saving and environmental protection are the two major themes of the development of modern society. In order to achieve sustainable development, energy-saving and environment-friendly products have become the development direction of modern industrial products. Among them, energy-saving and environment-friendly products that use batteries to provide electric energy have received widespread attention. [0003] As the power source of energy-saving and environment-friendly products, power battery packs are directly related to the performance of energy-saving and environment-friendly products. Taking electric vehicles as an example, at present, due to unreasonable structural design, electric vehicle power battery packs generally have defects such as low battery electrical connection reliability, large internal res...
