Introduce several ways to reduce the cost of lithium-ion battery packs

1. Increasing the size of lithium batteries. A lithium-ion battery pack is composed of hundreds of individual batteries in series and parallel. The batteries are the most important part of reducing the cost of lithium-ion battery packs. At present, battery companies are important in reducing the cost of battery cell manufacturing by reforming the material system, increasing the size of the battery cell, and improving the yield rate of the battery cell. In terms of increasing the size of the battery cell, whether it is square, cylindrical or soft-packed batteries, there is a growing trend of expanding the size of single cells. The benefit is to promote the energy density of lithium-ion battery systems and eliminate the number of cells. Lower costs. 2. Lightweight layout parts As an important component of lithium-ion battery packs and battery modules, the cell shell, top cover, steel/aluminum shell, positive and negative electrode soft connections, battery soft connections and other lithium-ion batteries are closely arranged. As far as possible, the cost of power lithium batteries is not large, but it has also become the focus of battery companies' demand for price reduction. At present, many manufacturers of lithium-ion battery packs are adopting methods such as introducing new materials and optimizing layout design to reduce the weight of new products by more than 20% compared with older products, and at the same time further reduce manufacturing costs, thereby reducing battery packs. The comprehensive cost. In addition to the above-mentioned layout parts, accessories such as boxes and wiring harnesses are also important departments where battery companies can directly spend their money. 3. Compared with other materials, BMS battery management system has a clearer depreciation. Many BMS company sources suggested that the cost of BMS only accounts for 5%-10% of the value of lithium-ion battery packs. However, under the pressure of subsidy decline, BMS company will also suffer from depreciation pressure, and estimate the value of 2018. The same in recent years has dropped by more than 20%. 4. Improve automation efficiency. Lithium-ion battery pack manufacturers are also effective ways for power lithium battery companies to reduce costs by improving production lines to automate production efficiency, and reducing cell manufacturing costs by limiting production. At the same time, by improving the production process, realize intelligent and limited production, improve the material operation rate and product pass rate, and greatly reduce the production cost of battery materials and battery packs. 5. The entire line of procurement reduces the cost of lithium-ion battery packs. Over the years, the output of power lithium batteries has expanded rapidly. Lithium battery production companies have gradually tended to package various equipment for bidding in order to reduce procurement costs. Orders and market share are slowly becoming the focus of the entire line of equipment. Large-scale lithium battery equipment companies meet.
