Lithium battery PACK factory shares a detailed explanation of module PACK process

In this article, we will explain the structure of the most critical step in the current battery manufacturing and molding. From the structure diagram, we will explain what functions we need to have in actual use of the battery, and how we can achieve this requirement in manufacturing; first, let us understand a few A concept power battery box (power battery box): capable of holding battery packs, battery management modules and corresponding auxiliary components, etc.; power battery pack: battery packs and battery management modules are equipped with external power supply and Externally powered module electromotive force: thermodynamic two-pole potential balance difference Eu003d∑ high-∑ low E: battery electric type ∑ high: positive balance total potential ∑ low: negative balance total potential 1. The stack of single cells is completed in the single cell manufacturing After that, according to the customer's model specification requirements, for example, a certain suv on the market requires 80 kWh of electricity, which is converted into the corresponding number of single cells according to the capacity of the single cell A; for example, a certain car on the market requires 75 kWh The amount of electricity is converted into the corresponding number of single cells according to the capacity of the single cell B; the first step we need to achieve in the process of implementing this function is to stack the single cells: single cell model The main function of group stacking has been completed at this step. From the perspective of safety-related and practical applications, we need to give it more requirements and practical functions; the first is the anti-collision requirement, which is to avoid excessive extrusion when a collision occurs. Unpredictable risks. We add flexible energy-absorbing materials between the single cells to improve the safety factor: the collision avoidance is optimized to this step and the functions are improved. However, in some occasions with higher safety requirements, we are concerned with the rigidity of the battery pack itself. There are higher requirements. At this time, we need to optimize the battery composition and stability: the structural reinforcement and the fixed plate are added to the module. At this time, the safety function can already meet the needs of most occasions in life, except for some off-road adventure subjects. Outside the test or rally event, the safety factor is sufficient, and then the value is increased, and the ratio of safety factor to cost drops sharply; in this situation, the demand shifts to the direction of safe and convenient development, which corresponds to the excessive number of single cells. One-by-one collection and optimization puts forward more requirements on control. For this reason, according to the different processes, we will make the battery corresponding to the series and parallel circuit layout. According to the different engineering applications, such as buses, buses, construction vehicles, taxis, family cars and other spaces The layout is different. In response to the needs of differentiated functions, we need to further refine the design and optimize the layout to meet actual needs: At the same time, in order to meet the needs of intelligent driving and automatic control, we need to provide safety assistance, thermal diffusion, In terms of integrated control, we will make coordinated upgrades; let electric vehicles better serve work and life, allow electric vehicles to enter thousands of households better, and make electric vehicles more affordable and more affordable. This is the main process of the module pack, and the actual production and manufacturing will focus on these processes and refine them; in particular, with the launch of blade batteries this year, the molding process of the module pack in the entire industry is undergoing major changes and corresponding new changes. We will gradually unveil the new veil after the new electric vehicle models are on the market; Statement: Some pictures and content of articles published on this site are from the Internet.
