In the era when Industry 4.0 has gradually come up, "Intelligent Manufacturing" is mentioned. Even a small chip is lamentable from the manufacturing environment, speed, accuracy, and scale. All this is due to the standard semiconductor manufacturing standard system. Compared with chips, if the company's annual production capacity reaches 8 billion watt-hours according to the requirements of the state, then the power battery will have a higher frequency than the chip manufacturing operations in the future. Furthermore, standard actions are very important for lithium-ion battery manufacturing, especially smart manufacturing.
With the approaching of 2020, China's strategic policy for the development of new energy vehicles has not wavered, and gradually improve the "subsidy retreat + dual points" combination of policy, so that the entire industry transition to the depth of the market. As the core components of new energy vehicles, the “three big mountains†of performance, capacity, and price of power batteries have been restricting industrial upgrading.
The addition of smart manufacturing has enabled power battery companies to find ways to climb over the “three mountainsâ€. The improvement of the intelligent level of the production line will increase product consistency and monitor the entire life cycle of the product, effectively guaranteeing the performance and safety of the vehicle. While the energy density of the battery has gradually reached over 350 Wh/kg, the life of the electric vehicle will continue to increase. Mileage approaching traditional fuel vehicles. From the market point of view, the production capacity is up, the cost is reduced, the market demand is met, and the value of the entire power battery manufacturing chain is also maximized. Not only the manufacturing end, including the R&D end, consumer end, etc., but also the entire power battery industry will have a tremendous transformation under the influence of “smart manufacturingâ€.
Today, our country has begun a forward-looking layout. From August to September this year, the Ministry of Industry and Information Technology released the "Notice on Organizing and Implementing the 2017 Smart Manufacturing Comprehensive Standardization and New Model Application Project" and the "2017 Smart Manufacturing Pilot Demonstration Project." Among them, the number of companies in the power battery industry chain has increased significantly. More than 10 companies, including Lucky, Grant, Micro-power, and Tianjin Lishen, have entered the list.
According to the plan, the “new mode application†project will be launched in 2019. The acceptance criteria will be the assessment indicators of production efficiency, operating costs, product development cycle, product non-performing rate, and energy consumption per unit of production.
"In fact, the concept of 'smart manufacturing' is very hot, but there are still a lot of distances and problems for our lithium battery company or lithium battery manufacturing." In March of this year, Yang Rukun, general manager of Shenzhen Jiyang Zhiyun Technology Co., Ltd. Say.
At present, the top-level design of the power battery in China is still not perfect. Since 2015, following the release of the new national standard and “Regulations for Automotive Power Battery Industryâ€, the country has successively formulated a number of power battery related standards. The most recent standard is the "Recycling and Dismantling Specification for Vehicle Power Battery" that was implemented on December 1. Relevant standards released in 2017 include "Specifications and Dimensions of Power Battery for Electric Vehicles", "Code for Code for Storage of Automotive Power Battery" and "Test of Recycling and Utilization of Vehicle Power Battery."
Industry standards have also been released, such as "Lithium Ion Battery Assembly General Requirements" and "Assembly Interface and Communication Protocol", "General Requirements for Lithium Manganese Battery Modules", and "Dimensional Specifications for Power Battery for Electric Vehicles".
In contrast, countries such as the United States, Japan, and the European Union have improved their power battery standards, have strong pertinence, and have a high degree of internationalization. These countries mainly refer to professional standards-setting organizations such as the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), the American Society of Automotive Engineers (SAE) and the United States Underwriters Laboratories (UL). The standard system developed by these organizations includes the design, manufacture, testing, installation, and acceptance of power batteries, combined with the development level of new energy vehicles, and makes corresponding standards and guidelines.
Obviously, no matter from the level of internationalization of the standard system or the construction of standards-setting organizations, China's power battery standard system needs improvement. In particular, it is worth noting that the standardization and establishment of a lithium-ion battery smart device has not yet been introduced in China.
In order to better help the new energy automotive power battery industry respond to changes in new markets, new policies, and new technology environments, on December 24th, Assistant to the President of the China Electrical Appliance Industry Association and Deputy Director of the Beijing Electrotechnical Institute of Mechanical Industry He will attend the "2017 Seventh China New Energy Vehicle Power Battery Summit" and "Standardization Status and Future Plans for Lithium Ion Battery and Equipment Manufacturing." At the meeting, he will make a detailed interpretation of the development status and future trends of power battery standardization, including the overall thinking and layout of the establishment of the standardization system, as well as the work of the association.
It is understood that the lithium-ion battery manufacturing equipment standard system has been established for one year, and is participated by the China Electrical Appliance Industry Association, the China Battery Alliance, and the Battery Professional Committee of the China Electronic Energy Technology Association.
In the early stage of the project, the company launched the “Finding a journey of intellectualization—a national battery industry smart equipment research and research tripâ€, and visited Guangzhou Fanzhong Electric Equipment Co., Ltd., Foshan Jinyinhe Intelligent Equipment Co., Ltd., and Dongguan Ali Automation Co., Ltd. Shenzhen Jiyang Intelligent Technology Co., Ltd., Han's Laser, and Hehe Technology have more than 20 companies.
Up to now, the lithium ion battery manufacturing equipment technology standard system contains 45 standard planning projects, and the project involves all aspects of lithium battery preparation. Among them, two industry standard projects “Lithium-ion battery pole piece coater†(2015-1325T-JB) and “Lithium-ion battery lamination machine†(2015-1326T-JB) have entered the standard solicitation commentary stage. National standard project "General Technical Requirements for Lithium-ion Battery Production Equipment" (20160533-T-604) A total of three standard projects have entered the draft stage, an industry standard "Lithium-ion battery winding equipment" (JB/T 12763- 2015) was approved for release in March 2016.
According to reports, the next phase of the project will focus on equipment intelligence standards, including automatic sealing equipment, capacitor automatic charge and discharge equipment, slurry high-speed dispersion equipment, slitting machine, continuous vacuum drying system, automatic casing equipment and lithium ion process NMP recycling equipment and other items.
With the innovation and upgrading of the new energy automotive industry, the power battery industry has several requirements for smart devices: First, the device has a standardized communication standard to achieve remote data collection and transmission, remote diagnosis and maintenance; Second, stability, high reliability and accuracy High, low energy consumption, and high degree of automation; Third, the use of information tools, the formation of in-depth integration of information technology and industrialization, to achieve deep learning, optimization, etc., and ultimately achieve the goal of large-scale intelligent manufacturing.
The 7th Annual New Energy Vehicle Power Battery Summit will be held in Qingyuan, Guangdong on December 24-25, with the theme “The Future of China's Power Battery under the New Energy Policyâ€. At that time, experts from domestic and foreign countries, academics, entrepreneurs, investors, government officials, and scientific researchers will discuss the major industries, focusing on the direction of electric vehicles and batteries, technical standards, testing and certification, new systems, new materials, new technologies, and new applications.
