CR927 battery.Analysis on assembly technology of power lithium battery

　　The process technology of the entire automotive lithium-ion battery industry chain has made breakthroughs, and the compatibility rate of consecutive batches of lithium battery materials has been greatly improved. It is reported that "Research on process technology, localized equipment, and echelon utilization and recycling technology of the entire lithium-ion battery industry chain" is a project supported by the 863 plan of the "Twelfth Five-Year Plan". The successful implementation of this project is a pioneering achievement of the research on the entire industry chain of core components of electric vehicles. , filling the gap in product application development of the entire domestic lithium-ion battery industry chain. This topic is combined with the national electric vehicle industry's "Twelfth Five-Year Plan" strategic development goals, aiming at the common problems existing in the pilot promotion process of electric vehicles in my country's public and private sectors, and the matching technology of the entire industry chain of power batteries with lithium iron phosphate batteries as the main form. At the core, through the integration of industrial chain resources, the problem of performance differences in continuous batches of material supply has been effectively solved, and the battery yield and assembly rate have been greatly improved. The increase in the matching rate is achieved on the basis of the improvement of the level of domestically produced equipment and equipment. The project implementer, Wanxiang Electric Vehicle Co., Ltd., a wholly-owned subsidiary of Wanxiang Group, has developed corresponding equipment and applied it on the production line. The electric energy in the conversion process The recovery rate has increased from 50% to more than 70%, shortening the formation time, reducing production costs, and improving the overall equipment level of the entire industry chain. The project also established a lithium battery recycling system, conducted a relatively systematic survey and analysis of domestic and foreign battery recycling technologies, developed a battery recycling process, and laid the foundation for the construction of a battery recycling pilot line. Wanxiang Electric has made remarkable achievements in high-power, high-energy power polymer lithium batteries, integrated motors and their drive control systems, vehicle electronic control systems, automotive engineering integration technology, and test and trial production platforms.
