Digital transformation difficulties, power battery intelligent manufacturing problems
Driven by the policy and market, China's new energy automobile and power battery industry has ushered in a new development opportunity in recent years. New energy vehicles (nevs) are strategic emerging industries in China, and power batteries, as the core components of nevs, are currently developing towards high-end and intelligent manufacturing. However, the road to the development of intelligent manufacturing is not a smooth one. Problems such as difficult connectivity and uneven standardization are still important factors hindering the realization of intelligent manufacturing of power batteries.
Intelligent manufacturing is imminent
According to the "power battery blue book" issued by China automotive technology research center co., ltd. in 2018, with the expansion of lithium battery market in China, lithium battery equipment industry has developed from basic lithium battery production to the direction of high precision, high safety, standardization and intelligence. As the development trend of power battery in the future, intelligent manufacturing can improve the product quality of battery enterprises, improve manufacturing safety and reduce production costs, which is of great significance for improving the overall competitiveness of China's power battery enterprises.
The reporter learned that at present, the global lithium battery industry is mainly concentrated in China, Japan and the rok, and the proportion of first-class lithium battery automation equipment in Japan and the rok is more than 70%, compared with about 50% of domestic first-tier enterprises and only 20% of second-tier enterprises. At present, China's power battery manufacturing industry has many problems, such as different technical routes, weak systematicness and inconsistency. This is also one of the important factors that cause the gap between Chinese power battery enterprises and Japanese and Korean enterprises.
Digital transformation is fraught with difficulties
For the power battery industry, from the selection of positive and negative electrode materials to battery testing and delivery, the whole process is very long and the data is extremely numerous. Lithium ion battery industry threshold is very high, mainly reflected in the capital intensive, technology intensive, process intensive. What we do is energy products, a little careless can easily lead to accidents. The lithium battery industry is becoming more automated, and while the industry feels it is moving fast enough, it is still far from what consumers want.
It is understood that the current domestic enterprises produce more than 150 kinds of cell specifications, which limits the development of standardized manufacturing to a certain extent. At present, there are many types of cell in the market, and the industry standard and national standard are not unified. As a result, the size of the cell is different and the module is not unified. Process standardization, size standardization, parts standardization is the basis of automation, do this basis, in order to achieve real intelligent intelligent production.
In addition, the data integration of information systems is also a major problem that puzzles the industry in its transition to digitalization. Sometimes all parts of the system are in place, but the final data can not be integrated, now the integration of domestic enterprises do very few. The production equipment is purchased in stages, the compatibility of connectivity is poor, and the problem of diversity has not been solved, resulting in incomplete data collection.
Pattern change is the soul
The task of digitalization is application and connection. The most important thing is to do a good job on the basis and platform and complete data collection. Data is collected and correlated before it can be fully utilized. The first step is to make top-level planning. From the workshop execution level, the factory management level to the enterprise operation level, it is necessary to build an intelligent manufacturing platform to achieve business integration and equipment integration, so as to reduce risks and improve productivity.
When it comes to the high threshold of intelligent manufacturing technology, although China is still short of original technology in many industrial software industry and lithium ion battery industry, we have a strong ability to apply what we have learned, and the technological progress in the lithium ion battery industry is very fast. I believe that the future information industry, including lithium ion battery industry will be better and better.
In the process of intelligent manufacturing transformation, mode change is the soul. It will be difficult for an enterprise to achieve intelligent manufacturing without changing mode, because many existing systems already exist. At present, we are still in the development stage from semi-automatic to automatic, and the next step is lean, informatization and digitalization. There is still a long way to go before we can achieve true intelligent manufacturing, and we still need to work together.
