[0004] 2. Another method is to arrange a certain number of batteries neatly and place them in a battery box. The battery box is designed to connect the batteries in parallel or in series, and then fix the relevant parts to form a module, and then install the module to the power battery. PACK is made on the frame. This method has problems such as difficulty in loading the battery cells into the battery box; and there are also problems such as many parts and cumbersome assembly and fixing.
[0006] (1) There are many types and quantities of parts and components, and the connection method is relatively complicated, resulting in low production efficiency and relatively high cost;
[0007] (2) The weight of the assembly is relatively large, and the specific energy and group efficiency are low;
[0008] (3) The volume of the assembly is relatively large, which is not conducive to the layout of the whole vehicle, but also reduces the space utilization rate of the whole vehicle

The invention discloses a soft package battery module structure for an automobile, and belongs to the technical field of automobile battery packs. The soft package battery module is mainly composed ofan aluminum alloy frame, a battery cell baffle, a battery cell PCB, a battery cell, a heat conduction plate, an aerogel plate, a heat conduction insulating plate and a fastener. The integrated aluminum alloy frame is adopted, a battery pack frame and a module support in the prior art are designed into the integrated aluminum alloy frame, the number and types of parts are reduced, and the production efficiency is improved; the soft package battery module is simple in structure, small in number of parts, convenient to assemble, light in weight, high in reliability and reasonable in manufacturing cost; and indexes such as specific energy, grouping efficiency and the like are greatly improved.
Description
technical field [0001] The invention relates to the technical field of automobile battery packs, in particular to a soft pack battery module structure for automobiles. Background technique [0002] At present, there are two main groups of pouch battery modules in the market: [0003] 1. One method is to arrange and fix the fixed bracket and the battery cell. The fixed bracket is provided with a fastening structure. A certain number of repeating units plus related auxiliary parts are used to make a module, and the module is then installed on the power battery frame to make a PACK, this grouping method has more accessories, which will reduce the volume energy density, and the module assembly and fixing are cumbersome. [0004] 2. Another method is to arrange a certain number of batteries neatly and place them in a battery box. The battery box is designed to connect the batteries in parallel or in series, and then fix the relevant parts to form a module, and then install the m...
