Effect of New National Standard on Lithium-ion Battery Industry

On August 31st, more than 400 CEOs and leaders of various sub-sectors of the lithium industry chain attended the meeting to jointly explore the development trend of the lithium industry and grasp the new direction of the lithium industry in the future. Through industry interaction, we will promote better cooperation between the upper and lower reaches of the industrial chain, and bring more breakthroughs and breakthroughs to China's lithium battery industry chain.

At this summit, Dr. Zhoujianxin, Director of Power Research and Development of Haishida, delivered a keynote speech on "The Impact of the New National Standard for power battery on the Lithium-ion Battery Industry."

The systematization of the new power battery national standard is more clear. GB/T31484, GB/T31485, GB/T31486 evolved from the QC/T743 standard, re-dividing the relevant content of the QC/T743 standard and upgrading it on this basis. Three separate standards have been developed that are more consistent with the actual use of electric vehicles. The GB/T31487 series standard is non-equivalent to the ISO 12405 series standard. Both sets of series standards are separately labeled for electrical performance and safety performance, which reflects the trend of China's power battery standards gradually developing into a system.

In addition, the scope of application of the six new national standards is more extensive, covering four levels: core, module, battery pack, and battery system. The types of products include hybrid, plug-in/augmentation hybrid, pure electric passenger vehicles, and commercial vehicles. It has basically formed a complete standard system of power battery systems.

At present, the new national standard test project is more comprehensive. The new national standard GB/T3148X has established a complete test system for the electrical performance and safety performance of individual batteries and modules. Among them, the operating cycle life, seawater immersion, temperature circulation, and low pressure are test items that are not included in the QC/T743 standard, and these projects are exactly the regular test items in the actual use and transportation of batteries. This paper shows that the new national standard pays attention to the actual use and transport performance of analog batteries, reflecting the concern of the new national standard for battery use and transportation performance. The new national standard GB/T31487.X has established a complete test system for electrical performance and safety performance for battery packs and systems, focusing on the overall safety performance of battery systems. For system-level security protection requirements, it was missing in previous national standards. The release of the new national standard GB/T31487.3 made up for this standard gap.

Dr Zhoujianxin pointed out that the new country has five major influences:

First, it helps to improve the standards system and improve the quality of market products. Due to the support of the policy for the new energy car industry, the profit of the power battery field has become prominent. In recent years, companies that have entered the battery field have grown in large numbers. At the same time, the former policy is relatively loose, the standard system is not perfect so that a large number of battery companies grow brutally, the product level is uneven, and low-quality products undermine fair competition in the market, laying a hidden danger for the safety of new energy vehicles. The implementation of the new national standard for batteries has positive significance for improving the standard system and improving the overall quality of market products.

The second is to promote technology competition and form a survival of the fittest. In April this year, the Ministry of Industry and Information Technology issued the "Supplementary Notice on Compliance with the" Battery Industry Code "and the subsequent publication of the" Regulations on the Administration of Access to New Energy Vehicle Manufacturers and Products ", setting a threshold for the power battery industry. By implementing relatively strict and demanding national standards, enterprises can be encouraged to commit themselves to technology research and development, and eliminate enterprises that are not up to standard in technology, so as to achieve the goal of guiding technological progress and achieve a competitive market atmosphere for the best and the worst.

The third is to provide unified standards for enterprises and provide technical support for supervision and management. The implementation of the new national standard has provided a unified measurement standard for vehicle companies and battery companies, clarified the main technical parameters of power batteries, and provided an important guarantee for the orderly development of the industry. At the same time, it also provides an effective quality supervision basis for the inspection and quarantine agencies and provides technical support for better supervision and management of imported and exported lithium ion battery products.

Fourth, we can benefit domestic battery companies. With policy support, China's new energy car market has expanded rapidly, and power batteries have benefited particularly. The new national standard is conducive to the development of domestic battery companies so that the Chinese automotive industry to achieve "curve overtaking."

Fifth, it brings opportunities and challenges. The new national standard has put forward stricter requirements for battery and system performance and has greatly improved the requirements for cycle life and safety performance. For enterprises that do not have a deep accumulation of products and technologies, it may be hasty or difficult to adjust technology to meet the new national standard. For enterprises that accumulate deeper, the pressure is relatively small.
