1. Increase the specification of lithium battery cells: a lithium battery pack is composed of hundreds of single lithium cells in series, and lithium cells are the key component of lithium battery pack cost control. At this stage, the key measures for rechargeable battery manufacturers to reduce the cost of lithium battery products are to improve the raw material management system, expand the specification of lithium battery, and improve the quality of lithium battery. In terms of large core diameter, rechargeable batteries with square, cylindrical or soft core diameter have already shown the development trend of single core diameter expansion at this stage. Its advantage is to improve the specific energy of lithium battery system software, reduce the core diameter and control the cost
2. Lightweight structural parts: lithium battery fine components, such as lithium cell shell, cover, steel/aluminum shell, positive and negative conductive soft connection, rechargeable battery conductive soft connection row, etc., although their cost often accounts for a small proportion in the power lithium battery, it has become the key for rechargeable battery manufacturers to seek price reduction
Now, many lithium battery pack manufacturers have reduced the net weight of new products by more than 20% compared with the old products according to the introduction of new materials, reasonable structural design and other countermeasures, and further reduced the manufacturing costs, thus reducing the comprehensive cost of battery packs. In addition to the above parts and components, auxiliary materials including shell, vehicle harness and so on are also key components of the immediate product cost of rechargeable battery companies
3. BMS rechargeable battery intelligent management system: Compared with other raw materials, the price reduction of BMS rechargeable battery intelligent management system is more significant. Many BMS personnel indicated that the cost of BMS only accounts for 5% - 10% of the lithium battery price. However, due to the pressure of subsidizing the decline in work, BMS will also encounter the pressure of price reduction. It is estimated that the price will fall by more than 20% in 2018
4. Improve the efficiency of automation technology: lithium battery pack manufacturing enterprises can improve the efficiency of production line automation and reduce the manufacturing costs of enterprises according to mass production, which is also an important way for power lithium battery companies to reduce product costs. In addition, according to the improvement of processing technology and production process flow, the intelligent system and import alternative production and manufacturing are completed, the utilization rate of raw materials and the rate of good products are improved, and the cost of lithium battery materials and PACK products is greatly reduced
