Problems solved by technology

Due to the different application requirements of the battery pack, the number of strings and parallels is very different. In the design of the battery pack, it is often necessary to design many kinds of battery pack structural parts. During the production, the processing of many parts needs to be made by opening molds, increasing the A lot of manufacturing costs, but also extended processing time

Abstract

The invention relates to a cylindrical lithium ion battery module combination unit. The cylindrical lithium ion battery module combination unit comprises a plurality of single cylindrical lithium ion batteries which are fixed by screws through a bracket; the bracket ensures that a safe spacing distance exists between the batteries and the single batteries are welded with welding and connecting sheets to form a parallel body. A plurality of screw holes in the bracket and a positive electrode (negative electrode) bus-bar form tight plane contact to be connected into a whole body when the screw holes are used for assembling a battery module. The welding and connecting sheets are formed by punching nickel-plated steel belts, nickel belts, copper belts and nickel-plated copper belts; the section area is determined by the maximum safe current value of the batteries. A plurality of battery module units are combined into various battery modules with different capacities and voltage grades through different arraying combinations. The modules are convenient to detach, maintain and replace; the module units are applicable to an application field of large-capacity battery modules for driving motors or energy-storage power stations.

Description

【Technical field】 [0001] The invention relates to a cylindrical lithium-ion battery module assembly unit, which relates to the assembly of a large-capacity battery module, using a certain number of cylindrical lithium-ion batteries to be combined into a general-purpose module unit through the support of a fixed bracket, and then the general-purpose The module unit is assembled according to the module design requirements and is suitable for the application field of large-capacity batteries that can drive electric motors or energy storage power stations. 【Background technique】 [0002] The battery module is assembled according to the requirements of use, through the series and parallel combination of single batteries, and equipped with corresponding control and protection components, which is convenient for installation and maintenance, and can meet the use requirements of the battery pack. Lithium-ion battery is an advanced chemical energy storage device with significant adva...
