To meet the requirements of automotive-grade products, key aspects include structure, electrical design, thermal design, and safety. Sufficient compression force is applied according to the requirements of the battery cell, which will be discussed later. The entire battery cell, whether it is a soft-pack or hard-pack, can effectively prevent cell expansion through certain measures, thus providing support for its lifespan.
Within the entire lithium-ion battery pack, there's a module-to-pallet fixing mechanism, using pressure strips to effectively secure the module to the tray. Importantly, this includes the sampling lines and measures to prevent cell movement within the pack. Under normal NETT conditions, cell heat generation is not significant. However, we must consider extreme scenarios, such as users engaging in high-speed driving or long-distance fast charging, which places high demands on heat transfer. Safety and the cell insulation requirements within the module design are closely related.
Part Two: Manufacturing Process
The most important thing is to handle the entire process of battery cells, from individual cells to stacking, welding, sampling line layout, and CMU layout. There are requirements for distance and process assembly. This part is closely related to the equipment, especially when mass production is carried out, and especially when going to automated production lines.
Part Three: Maintenance Considerations
When we are doing this now, the first step is to make the product. Later, as the vehicle is used, the maintenance of the entire lithium-ion battery module, especially the damage to the related sub-components, and how to repair the module, needs to be combined with the manufacturing process and maintenance process. This is something that people don't talk about much.
Part Four: Module Cascade Utilization
Generally speaking, after we have sorted out the requirements for lithium-ion battery packs, we will design a module block diagram. The important thing is to connect all the parts, including electrical, structural, vehicle coupling, and mechanical fixation aspects, and input the requirements for the electrical and structural parts into it. This way, we can clarify the design goals of each part.
