China's power battery laser welding equipment demand space calculation
Huatai Securities recently released a research report on China's laser industry. In the report, it analyzed the continued growth of demand for new energy vehicles and promoted the promotion of the laser equipment market after the expansion of the power battery industry. It is expected to show during the 13th Five-Year Plan period. The investment in power batteries will reach 56 billion yuan, corresponding to the demand for laser equipment of 5.6 billion yuan.
Demand for new energy vehicles continues to grow, driving the expansion of the power battery industry. Affected by the reduction of subsidies for new energy vehicles, the sales volume of domestic new energy vehicles in the first half of 2017 was 195,000 units, up only 14.71% year-on-year. It is estimated that the annual sales volume will be about 700,000 units. However, the “Technology Roadmap for Energy Saving and New Energy Vehicles†issued by the Ministry of Industry and Information Technology at the end of October 2016 proposes that by 2020, the proportion of new energy vehicle sales to total vehicle sales will reach 7% or more; by 2025, new energy vehicle sales will account for the total sales of automobiles. The proportion will reach more than 20%; by 2030, the proportion of new energy vehicle sales to total vehicle sales will reach more than 40%. The general trend of automobile electrification is relatively certain, and the growth of power battery is determined.
2011-2016 China's lithium battery shipments and growth
The concentration of the power battery industry has increased, and first-tier manufacturers are expected to continue expansion. On March 1, the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology, the Ministry of Science and Technology and the Ministry of Finance announced the issue of the “Action Plan for Promoting the Development of Automotive Power Battery Industry†to accelerate the development of China's automotive power battery industry. Promote the healthy and sustainable development of the new energy automobile industry. The plan proposes that by 2020, the total capacity of the power battery industry will exceed 100 Gwh, and a leading enterprise with an international competitiveness will be formed with a production and sales scale above 40 Gwh. EVtank According to statistics, by 2016 lithium battery shipments 30.5Gwh, and the highest proportion of BYD shipped 8.3Gwh. If we assume that we reach the program target by 2020, the compound compound growth rate will reach 34.56%. Taking into account the higher technical barriers in the industry, we believe that the growth rate of leading technology companies may be greater than the growth rate of the industry, industry concentration will continue to increase, and first-tier manufacturers will accelerate the expansion of production.

Laser welding has great advantages in technology and high safety, and will be the preferred process for power battery production. The battery manufacturing process involves a wide range of welding techniques, such as ultrasonic welding, electric resistance welding and laser welding. Laser welding is a very important process in the production of batteries. It has a great influence on the consistency, stability and safety of the battery. The laser welding parts of the power battery are numerous, the process is difficult, and the welding process is more demanding. Laser welding consumables have low loss, small deformation of welded workpieces, stable and easy operation of equipment, high welding quality and automation. Through high-efficiency and precise laser welding, the safety, reliability and service life of automotive power batteries can be greatly improved, which will surely provide important guarantee for the development of automotive power technology in the future.
New energy vehicle sales
During the 13th Five-Year Plan period, the investment in power batteries will reach 56 billion yuan, corresponding to the demand for laser equipment of 5.6 billion yuan. Assuming that the country will reach the goal of the Action Plan for Promoting the Development of Automotive Power Battery Industry by 2020, then between 2017 and 2020, the domestic new capacity of power batteries will be about 70 Gwh. According to the incomplete statistics of the investment situation of some power battery projects, the investment amount per Gwh new capacity is about 800 million yuan, while the laser welding equipment accounts for 5 to 15% of the power battery plant investment, then the domestic power will be 2020. Battery plant equipment demand is about 28 to 8.4 billion yuan.
New energy vehicle sales share

Near the Mid Autumn Festival, various moon cake iron boxes with exquisite patterns can be seen everywhere. The moon cake iron boxes on the market are getting better and better each year. Of course, a good Iron Box is not measured by its beautiful appearance, but by its good quality. Good quality. We can use it again after using it. Then, how to judge whether the quality of the iron box has reached the standard?
When we first see the iron box, we will have an objective judgment on the box. The first thing we see is the surface of the iron box. The information reflected on the box surface, such as patterns, printing, barcodes, models and specifications, is not randomly placed. It has certain rules. The randomly printed iron box is already unqualified on the surface. Again, check the box surface for scratches, and the printed surface shall not be greater than 0.3mm * 20mm. On the front side, the pattern of the product surface is placed directly in front of and below the sunlight. In addition to the main viewing surface of the box, you can also see the inner surface, side, bottom, etc.
The above are the tips that can manufacturers share with you on how to judge whether boxes are standard. Have you learned?
