Briefly describe the design and production process flow and key points of cr2032 3v lithium battery modules

The design and production process flow and key points of cr2032 3v lithium battery modules. The power cr2032 3v lithium battery module connects several single cells in series and parallel through conductive connectors to form a power source, fixes them in the designed position through process and structure, and synergizes the functions of charging, discharging and storing electric energy. It can be said that the basic function of the module is connection, fixation and safety protection. The connection method between the cell monomer and the module busbar not only affects the manufacturing efficiency and whether it can be automated, but also has an impact on the performance of the battery after it is installed on the vehicle. Introduction to cr2032 3v lithium battery modules cr2032 3v lithium battery modules can be understood as an intermediate product between cells and packs formed by combining lithium-ion cells in series and parallel, and adding single cell monitoring and management devices. Its structure must support, fix and protect the cells, which can be summarized into three major items: mechanical strength, electrical performance, thermal performance and fault handling capability. Whether the battery cell can be properly fixed and protected from deformation that may damage its performance, how to meet the current-carrying performance requirements, how to control the battery cell temperature, whether it can be powered off in the event of a serious anomaly, whether it can avoid the spread of thermal runaway, etc., will all be criteria for judging the quality of cr2032 3v lithium battery modules. For cr2032 3v lithium battery modules with high performance requirements, the thermal management solution has turned to liquid cooling or phase change materials. There are many internal connecting wires in the cr2032 3v lithium battery pack, and there are too many manual welding steps, which leads to problems such as welding and assembly; there are too many parts, which makes assembly difficult, with a high failure rate and high cost. The entire cr2032 3v lithium battery module design process actually includes defining the goals of the entire module design, integrating the details of the module design, and having a complete set of module design verification processes, including structure, electrical, and cooling safety. The first part is divided into several design levels to meet the requirements of the vehicle-mounted product, which are mainly divided into structure, electrical design, thermal design, and safety. Sufficient compression force is given according to the requirements of the battery cell. This compression will be discussed later. The entire battery cell, whether it is a soft pack or a hard shell, can effectively prevent the expansion of the battery cell through certain measures, and provide certain support in terms of life. There is also a module and tray fixation in the entire cr2032 3v lithium battery pack, and the module and tray are effectively fixed through the pressure strip. The above is mainly the sampling line inside, and it also prevents the battery cell from moving inside. The heating of the entire battery cell is not serious under normal NETT working conditions. We also have to consider that there may be some extreme situations, that is, the user may be on the highway, which is equivalent to entering the fast charging state during long-distance driving. The continuous limit meets the requirements, and there may be a strong heat transfer requirement here. Safety and the battery cell insulation requirements in the module design have a strong connection here. The second part, the manufacturing process is mainly to stack the cells from single cells to welding, sample line layout, CMU layout, the entire process, equipment, distance, process assembly are all required, this part needs to be connected with 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, and later with the use of the vehicle, the maintenance of the entire cr2032 3v lithium battery module, especially the damage to the sub-components inside, how to repair the module, here should be combined with the manufacturing process and maintenance process, here is also less discussed. The fourth part, module cascade utilization, generally speaking, after we sort out the requirements of our cr2032 3v lithium battery pack, we will design a module block diagram, mainly to connect all parts, including electrical, structural, vehicle coupling, mechanical fixation, and input the requirements of the electrical structure part into it, so that we can make the design goals of each part clear. Key points of cr2032 3v lithium battery module structure design The structure of cr2032 3v lithium battery pack is reliable: anti-vibration and anti-fatigue; process controllable: no over-welding, false welding, ensuring that the battery cell is 100% undamaged; low cost: PACK production line automation cost is low, including production equipment and production loss; easy to disassemble: cr2032 3v lithium battery pack is easy to maintain and repair, low cost, and the battery cell can be used in stages; necessary heat transfer isolation is achieved to avoid the rapid spread of thermal runaway, and this step can also be considered in pack design. It is understood that at present, the module grouping efficiency of cylindrical cells in the industry is about 87%, and the system grouping efficiency is about 65%; the module grouping efficiency of soft-pack cells is about 85%, and the system grouping efficiency is about 60%; the module grouping efficiency of square cells is about 89%, and the system grouping efficiency is about 70%. The single energy density of soft-pack cells has higher room for improvement than that of cylindrical and square cells, but the requirements for cr2032 3v lithium battery module design are higher, and safety is not easy to control. These are all problems that need to be solved by structural design. General cr2032 3v lithium battery pack module optimization path. Improving space utilization is also an important way to optimize modules. Power cr2032 3v lithium battery pack PACK companies can improve the space utilization rate of the battery box by improving the design of modules and thermal management systems, reducing the distance between cells. Another solution is to use new materials. For example, the bus in the power battery system is replaced by aluminum from copper, and the module fixings are replaced by high-strength steel and aluminum from sheet metal materials, which can also reduce the weight of the power battery. The power cr2032 3v lithium battery module connects several single cells in series and parallel through conductive connectors to form a power source, and fixes them in the designed position through process and structure, so as to synergistically play the function of charging and discharging electricity.
