What are the ways to reduce the cost of lithium battery packs?

1. Increase the size of lithium batteries. A lithium battery pack consists of hundreds of individual batteries in series and parallel. The batteries are the most important part of reducing the cost of lithium battery packs. At present, battery companies mainly improve the material system, enlarge the cell size, and increase the cell yield in terms of reducing the manufacturing cost of battery cells. In terms of increasing the size of the battery cell, whether it is square, cylindrical or soft pack batteries, there is a development trend of expanding the size of single cells. The advantage is that it is conducive to the increase of the energy density of the lithium battery system and the reduction of the number of cells. cost. 2. Lightweight structural parts As an important part of lithium battery packs and battery modules, the battery cell shell, top cover, steel/aluminum shell, positive and negative electrode soft connections, battery soft connection bars and other lithium battery precision structural parts, although in The cost of power lithium-ion battery is not large, but it has also become the focus of battery companies' request for price reduction. At present, many lithium battery pack processing manufacturers are introducing new materials and optimizing structural design in 2018 to reduce the weight of new products by more than 20% compared with old products, and at the same time, further reduce manufacturing costs, thereby reducing the cost of battery packs. overall costs. In addition to the above-mentioned structural parts, accessories such as boxes and wiring harnesses are also an important part of the cost that the battery company can directly reduce. 3. Compared with other materials, the price of BMS battery management system is more obvious. A number of BMS companies said that the cost of BMS only accounts for 5%-10% of the price of lithium battery packs, but under the pressure of subsidies to decline, BMS companies will also bear the pressure of price cuts. It is expected that the price of 2018 may be year-on-year. Decrease by more than 20%. 4. Improving automation efficiency. Lithium battery pack processing manufacturers improve the automated processing efficiency of production lines and reduce unit manufacturing costs through large-scale processing are also effective ways for power lithium-ion battery companies to reduce costs. At the same time, by improving the process and processing, realize intelligent and large-scale processing, improve the utilization rate of materials and the product qualification rate, and greatly reduce the processing cost of battery materials and battery PACK. 5. The entire line of procurement reduces the cost of lithium battery components. In recent years, the output of power lithium-ion batteries has expanded rapidly. Lithium battery processing companies have gradually tended to package various equipment for bidding to reduce procurement costs. Concentration of large lithium battery equipment companies. The continuous decline in the processing cost of lithium battery packs is the result of a series of factors, including policy orientation, process technology, processing scale, equipment procurement costs, and the subjective will of industry talents.
