Embodiment Construction

[0029] like 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:

[0030] 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.

[0031] 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 batt...

Abstract

The invention discloses a cylindrical power battery module structure which comprises at least two battery modules connected in series with each other. Each battery module comprises a battery cell group, a battery cell bracket, an anode nickel piece, a cathode nickel piece and a circuit board; the battery module structure comprises a nickel piece connection rigid pressure plate, nickel piece connection bolt and nut, module connection bolt and nut and a support; the battery cell brackets, the battery cell groups, the anode nickel pieces and the cathode nickel pieces are assembled to form the battery modules; and the battery modules are connected into a battery module through the nickel piece connection rigid pressure plate, the nickel piece connection bolt, the nickel piece connection nut, the module connection bolt, the module connection nut and the support. According to the invention, the nickel pieces among the battery modules are connected by the multipoint bolts of the rigid pressure plate; the nickels of the module are in direct close pressure-equalizing connection, and the little total internal resistance, low self consumption and high reliability of electric connection of the module are guaranteed; the anode side structure and the cathode side structure of the battery module correspond to and are matched with each other; the capacity expansion of the battery module is facilitated, and the standard design of the battery module structure is easy to realize; and large-scale production is facilitated, and the manufacturing cost is lowered.

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...
