The first part is divided into several design levels
To meet the vehicle-mounted product demand characteristics, it is mainly divided into structure, electrical design, thermal design, and safety. Sufficient compression force is given according to the requirements of the battery core. This compression will be discussed later. The entire battery core, whether it is a soft package or a hard shell , through certain measures, the expansion of the battery core can be effectively prevented and the life span can be given certain support.
There is also a fixation between the module and the tray in the entire lithium-ion battery pack. The module and the tray are effectively fixed through pressure strips. The important thing above is the sampling line inside, and preventing the battery core from moving inside. The entire battery core does not generate serious heat under normal NETT working conditions. We also have to consider that there may be some extreme situations, that is, the user Maybe it's on the highway, which is equivalent to entering the fast charging state when driving long distances, and the continuous limit is met. There may be a strong heat transfer requirement here. There is a strong connection between safety and the battery core insulation requirements in module design.
Part 2, Manufacturing Process
Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%
Charging temperature: -20~45℃ -Discharge temperature: -40~+55℃ -40℃ Support maximum discharge rate: 3C -40℃ 3C discharge capacity retention rate ≥70%

The most important thing is to arrange the cells from single cells to stacking to welding, sampling line layout, and CMU layout. The entire process, equipment, distance, and process assembly all have requirements. This part must be followed by the equipment, especially when taking measurements. Especially when it comes to automated production lines, there is a strong demand connection.
Part Three, 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-ion battery module will be repaired, especially the damage to the sub-components inside. How to repair the module? , it needs to be combined with manufacturing technology and maintenance technology, and people talk less about it here.
