What are the basic points of the structural design of lithium battery modules?

The structure of the lithium battery pack is reliable: anti-vibration and anti-fatigue; process controllable: no over-welding, false welding, to ensure that the battery cell is 100% free of damage; low cost: low cost of automation of the PACK production line, including processing equipment and processing loss; easy to separate : Lithium battery packs are easy to maintain and repair, low cost, and battery cells can be used in cascades; to achieve necessary heat transfer isolation to prevent thermal runaway from spreading too quickly, this step can also be considered in pack design. It is known that at present, the grouping efficiency of cylindrical batteries in the industry is about 87%, and the grouping efficiency of the system is about 65%; the grouping efficiency of soft-packed batteries is about 85%, and the grouping efficiency of the system is about 60%. ; The grouping efficiency of the square cells is about 89%, and the grouping efficiency of the system is about 70%. The single energy density of the soft-packed battery cell has a higher room for improvement than the cylindrical and square, but the design requirements for the lithium battery module are higher, and the safety is not easy to control. This is a problem that needs to be solved by structural design. General optimization approach for lithium battery pack modules. Improving space utilization is also an important way to optimize modules. Power lithium battery pack PACK company can improve the design of modules and thermal management system to reduce the cell spacing, thereby improving the utilization of the space in the battery box. Another solution is to use new materials. For example, the busbar in the power lithium-ion battery system is replaced by copper with aluminum, and the module fixing parts are replaced by sheet metal materials with high-strength steel and aluminum, which can also reduce the weight of the power lithium-ion battery.
