AG3 battery

Power AG3 battery with intelligent manufacturing

In the past two years, my country's new energy vehicle industry has developed rapidly, bringing rare opportunities to related industries such as power batteries. With the rapid expansion of the power battery and energy storage battery market, higher requirements are put forward for battery quality. Battery manufacturing will develop in the direction of "high quality, high efficiency, high stability" and "informatization, unmanned, and visualization".

Therefore, my country's battery companies must accelerate the pace of intelligent manufacturing of batteries through technological innovation, production automation and management standardization, promote battery products to enter the high-end market more, and meet the high requirements of new energy vehicles and energy storage applications for battery quality.

Current status of the power battery industry

According to the "Medium- and Long-Term Development Plan for the Automobile Industry" issued by the Ministry of Industry and Information Technology, the production and sales of new energy vehicles will reach 2 million in 2020, and the ownership will reach 5 million; in 2025, new energy vehicles will account for more than 20% of automobile production and sales. We are optimistic about the country's expected goals for the new energy vehicle industry. By 2020, the power battery industry will also expand significantly with the growth of the new energy vehicle industry. my country's power lithium-ion battery industry has ushered in a rare development opportunity, and all power lithium-ion battery manufacturers are in short supply.

In recent years, my country's new energy vehicle industry has developed rapidly. In addition to people's energy conservation, emission reduction and environmental awareness, the main reason is the strong support of various favorable policies such as national fiscal subsidies. Many companies have invested in the field of new energy vehicles. However, although the high subsidies and the inclusiveness of subsidies have accelerated the promotion of new energy vehicles, they have brought a series of problems such as fraud, overcapacity, and shoddy workmanship, which objectively affect the choice of technical paths and even affect technological innovation.

At present, my country's new energy vehicle power battery industry is still small, scattered, chaotic, and the entire industry is blindly invested and low-level construction. The technical level and product quality need to be further improved. In the short term, the overall capacity of power lithium batteries is in excess, the supply of low-end capacity is far greater than the demand, the industry competition is fierce, the high-end capacity is insufficient or blank, and the gap between the super echelon and the first echelon is large. In 2018, power battery companies will accelerate the survival of the fittest.

Accelerating intelligent transformation is the key

At present, in order to improve the consistency of power batteries produced, improve production efficiency, improve information management, reduce labor, and reduce labor intensity; at the same time, in order to meet the needs of mixed-line production of batteries of different specifications in the production process of power batteries, the construction of automated and intelligent production logistics systems and intelligent manufacturing systems has become an inevitable trend.

On the one hand, for power battery companies, the implementation of intelligent manufacturing can improve efficiency, reduce costs, improve quality, improve material utilization, shorten product development cycles, reduce labor costs per unit of production capacity, and accelerate on-site management transparency, thereby enhancing the competitiveness of enterprises; on the other hand, while promoting the transformation and upgrading of power batteries, it can promote the development of high-end equipment for power batteries. Therefore, intelligent manufacturing is also an important means to achieve various indicators of power batteries.

When power batteries meet intelligent manufacturing

The development of intelligent manufacturing encounters many obstacles

First, the hardware equipment of domestic AG3 battery manufacturers is mostly segmented, and there are compatibility and diversity issues between equipment, resulting in low integration between various industrial software and data cannot be shared and circulated.

Second, the amount of data collected for the production and testing of lithium-ion products is large, each process has different control requirements, and the manufacturing model is a mixed model of process-based and discrete models, which exacerbates the difficulty of industrial digitalization/intelligent manufacturing;

Third, the standard specifications of power battery sizes are not unified. Our domestic companies have produced more than 150 different specifications of battery cells, resulting in relatively small sales of a single model, which limits the development of standardized, large-scale, and intelligent manufacturing.

Fourth, the product design and manufacturing process technology of power batteries are not fully mature, especially the key production process design of battery modules is immature, the verification is not sufficient, the one-time pass rate is low, and it is difficult to achieve online automatic testing and quality tracking. Therefore, the production of power battery systems is still mainly semi-automated, and only a few battery manufacturers have achieved automated production of power battery modules or modules.

The domestic power battery industry is currently still in the "foundation-laying" stage of intelligent manufacturing. The outstanding bottleneck of domestic power batteries at the low end is the core process and complete equipment. Power battery equipment involves dozens of production processes and seven modules of power batteries. Compared with foreign equipment, domestic equipment has a certain gap in accuracy, speed, reliability, unmanned operation, visualization, and informationization. Therefore, mid-to-high-end equipment is currently mainly imported.

Therefore, the industry's top priority is to establish a set of information models for battery factory products, processes, and quality, and to achieve digitalization on the basis of the establishment of information models, and to achieve intelligence through big data analysis, accumulation, and optimization. At the same time, it is necessary to accelerate the promotion of manufacturing process and equipment standardization. Going forward at both ends can accelerate the standardization, modularization, and digitalization of the manufacturing process, and then achieve data-based intelligence.
