What is the general process of designing and processing lithium battery modules?

The first part is divided into several design levels to meet the demand characteristics of the vehicle equivalent of the product. It is mainly divided into structure, electrical design, thermal design, and safety. Sufficient compression force is given according to the requirements of the battery. This compression will also be discussed later. The entire battery Regardless of whether it is a soft case or a hard case, a certain amount of addition can effectively prevent the expansion of the battery core and provide certain support in terms of life. There is also a fixation between the module and the tray in the whole lithium battery pack, and the module and the tray are effectively fixed through the pressure bar. The most important thing above is the sampling line inside, as well as to prevent the cell from moving inside. The heating of the whole cell is not serious under normal NETT conditions. We must also consider that there may be some extreme situations, that is, the user It may be at a high speed, which is equivalent to saying that the long-distance driving enters the fast charging state, and the continuous limit is met, and there may be a strong heat transfer requirement here. There is a strong connection between safety and the thermal insulation requirements of the cell in the module design. In the second part, the most important part of the manufacturing process is to change the battery cell from single unit to stacking to welding, sampling line layout, CMU layout, the entire process, equipment, distance, process assembly are required, this part must be related to the equipment, especially When it comes to volume, especially when it comes to automated production lines, there is a strong demand connection here. The third part, maintenance considerations. Because when we are doing it now, the first step is to make the product. Later, as the vehicle is used, the entire lithium battery module is repaired, especially the damage of the relevant sub-components. How to repair the module, here must be combined with the manufacturing process and maintenance process, here is less talked about. The fourth part, module echelon utilization. Generally speaking, we will design a block diagram of the module after we sort out the requirements for lithium battery packs. It is important to connect all parts, including electrical aspects, structural aspects, vehicle coupling aspects, and mechanical fixing aspects. Get up and enter all the requirements of the electrical structure into it, so that we can clarify the design goals of each part.
