New energy vehicle strength PK electric car?

The development of new energy vehicles is an important national strategy as well as an important thrust for supply-side reforms. Policies have increased the support and propulsion of power battery smart manufacturing. No matter how the capital is hype, the manufacturing properties of the battery industry will not change, and the quality of batteries will still depend on innovative technologies, manufacturing processes, and manufacturing levels.

Recently, Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, introduced the work plan of the Ministry of Industry and Information Technology on the next step in the development of the power battery at the 2017 Annual Conference of China Automotive Power Battery Industry Innovation Alliance. Several key tasks are related to battery manufacturing, such as:

With respect to safety issues, it is necessary to further enhance the level of production automation and intelligence;

With regard to providing support for new energy vehicles, it is necessary to speed up the development and manufacture of power battery equipment and accelerate the development of large-scale intelligent manufacturing technologies and equipment;

With regard to collaborative innovation in the whole industry chain, we must build a number of public service platforms that promote collaborative innovation in the manufacturing industry.

With respect to recycling and step utilization, consideration should be given to product design, manufacturing processes, and equipment.

It can be seen that the Ministry of Industry and Information Technology attaches great importance to intelligent battery manufacturing. Increasing the level of manufacturing has become a breakthrough for the further development of the battery industry. In the future, smart manufacturing is also an important direction for battery companies.

It is generally believed that intelligent manufacturing is a product of the integration of manufacturing technology with digital technology, artificial intelligence technology, and a new generation of information technology. It is oriented toward the entire product lifecycle and has the functions of information perception, optimization decision-making, execution control, and deep learning. Its purpose is Reduce costs, shorten production time, improve product quality, and achieve environmental protection.

From 2012, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Finance jointly organized the implementation of smart manufacturing equipment special projects, and the Ministry of Industry and Information Technology announced the “Detailed Rules for the Acceptance of Integrated Application and Standardization of Intelligent Manufacturing and New Models (Interim)”. Smart manufacturing has developed rapidly in China. Today, hundreds of digital production lines, workshops, and factories have been built or are under construction in the country, and powerful battery manufacturers have joined the smart manufacturing industry.

The old battery company kept pace with the times and spared no effort in battery smart manufacturing. I have visited BYD battery factory. The entire production workshop is magnificent and the level of automation is rare in China. As of March 2017, BYD's production capacity is 16GWh, and Qinghai's 10GWh plant has already been built. It is expected that the capacity will reach 26GWh by 2018. Behind its huge capacity scale is the strong support provided by smart manufacturing.

The cost reduction of battery companies is an important way to increase market competitiveness. Large-scale manufacturing and intelligence are the direction of production, and they are also the main way to reduce costs and improve quality. Shen Ye, Senior Director of BYD Battery, believes that the core of the cost reduction is automated equipment, process inspection systems, manufacturing execution systems, etc. They must form an integrated system.

In addition, Wattmar's battery automation PACK shop (also known as the Wattmar Wisdom factory) is also impressive. All processes, such as gearing, welding, coating, clamping, assembly and testing of the production line, have been converted from manual to manual. automatic. The workshop is characterized by automation, information and intelligence, and forms a comprehensive system integrating data, information and services.

Lithium-electric companies need to break through the difficulties of traditional manufacturing models, and smart manufacturing is a must-winning highland. As the author combed Haisida's manufacturing system, he found that it could also be used as a typical example of intelligent battery manufacturing.

Hai Sida was established in 1992 and is a senior-level battery company. It has continuously transformed and upgraded over the past 25 years and witnessed the ups and downs of the battery industry. In terms of battery manufacturing, for the problems of poor consistency, low efficiency, and low cost control capabilities, Haisida's solution is to improve the control accuracy of production equipment and the automation level of the production line. The company introduced South Korea equipment production line to achieve automation and intelligence across the board, effectively shortening the product development cycle. At the same time, Haisida also increased the digitization level of the factory and realized digitalization of incoming materials and digitalization of equipment. The intelligentization of battery manufacturing has enabled Haisida to increase production efficiency and product quality, and it is also important for its transformation and upgrading.

Also as a veteran battery company, Yiwei Lithium's changes in battery manufacturing can be described as earth-shaking and extremely inspiring. In 2001, when Yili Lithium was able to establish in Huizhou, due to financial constraints, it was unable to purchase key equipment, and the company could only adopt a semi-automated approach of “man + machine”. In these years, YiWei Lithium has continuously increased its investment in independent research and development and achieved the technological transformation of “Manual—Automation—Industry 4.0”.

In June 2016, Yili Lithium was able to put into production a fully automated lithium-ion battery production line. It is a high-level automation factory in China. The per capita output value has increased from the previous 800,000 to 900,000 yuan to the current 10 million yuan. , turned up 10 times. According to the semi-annual report of Yilv Lithium Energy, in the first half of 2017, the company realized operating income of 1.344 billion yuan, up 63.65% over the same period of the previous year, of which lithium-ion battery business realized operating income of 397 million, an increase of 155.63% over the same period of last year . Yiwei Lithium Energy said that an important reason for its outstanding performance was the release of the company's power battery capacity, resulting in an increase in performance. Of course, behind the good results is the beautiful transformation of Yiwei Lithium in the smart manufacturing of batteries.

Intelligent manufacturing is the future trend of battery production. It is an important way for companies to improve battery quality and capture the market. Compared with the old companies in the industry, the young battery companies are less constrained by the old production lines, and it is more convenient to realize the intelligence of the battery production line. The old company's development through many years also has its inability in terms of capital, management, and technology. The advantages of substitution.

Yilv Lithium, Haisida, BYD and Waterma are just a microcosm of the intelligent process of battery manufacturing in China. Under the backdrop of industry reshuffling, the upgrading of battery production equipment is also accelerating, and many battery companies are taking the initiative or Passively joining the wave of intelligence, the gap between the battery companies that implement smart manufacturing and those that have not implemented smart manufacturing will also be widened.
