How to Promote Better Development of the Lithium Battery Testing Equipment Industry?

Lack of industry standards for lithium battery testing equipment How to promote better development of the industry?

• In recent years, environmental problems have occurred frequently. The country vigorously develops the new energy automobile industry, the introduction of standardized conditions and the subsidy of policy dividends “two-pronged”, and the effect is quite fruitful. As an important branch of the new energy automobile industry chain, the development of power battery testing equipment is in a period of explosive growth. If you want to manufacture lithium batteries and battery packs with high consistency, good stability, and excellent performance, testing equipment will play a vital role.
• However, since the commercialization of lithium batteries for more than 20 years, the product specifications and models on the market have not achieved standardized production. In order to meet the different needs of downstream battery companies, lithium battery testing equipment companies have long been tired of R&D and production of various “non-standard” equipment, resulting in high equipment costs and difficulties in stable upgrades. At the moment when power lithium battery manufacturing has greatly increased equipment requirements, this has affected the safety improvement, cost reduction and large-scale production of power lithium batteries.
• There are many types of testing equipment, how to develop oneself
• Although the prospects are highly positive, there are still many problems in the lithium battery market. At present, the domestic downstream lithium battery manufacturing process has not been unified, and the lithium battery specifications and models on the market are diverse, making it difficult for the equipment industry to achieve standardization. As a well-known domestic lithium battery testing equipment company, we have always hoped that relevant parts can issue relevant industry standards. In order to facilitate the development of the entire lithium battery industry, the scale of the industry will be further expanded, and the economic effect will also be enhanced.
• As the core component of electric vehicles, what testing standards are involved in power lithium batteries? At present, domestic power batteries for electric vehicles mainly include GB/T 31484-2015, GB/T 31485-2015, GB/T 31486-2015 and GB/T31467.1/2/3 and other 6 standard requirements. The three standards 484, 485, and 486 need to be used in conjunction. 484 is for cycle life requirements, 485 is for safety requirements, 486 is for battery electrical performance requirements, and 467 is for battery packs and system electrical performance and safety. Testing requirements.
• In the field of power batteries, our company is responsible for the testing of related manufacturing and testing equipment from many well-known manufacturers such as BYD, Lishen, ATL and Coslight. From the perspective of battery electrical performance, battery testing equipment is mainly used to test battery capacity, energy, and internal resistance in different states to test the consistency, life, stability and safety of the battery. This requires testing equipment to perform well in terms of voltage/current accuracy, response speed, sampling rate and stability.
• Our testing equipment has high stability, fast sampling speed, and high accuracy value. As early as a few years ago, it can run for a long time and maintain 0.05% without calibration (industry demand is generally 0.1%). At present, our testing equipment has been widely used in standard laboratories, including national laboratories and laboratories of scientific research institutions. In addition, we can achieve a high precision of two ten thousandths according to the needs of customers (this is the test standard). Attention to market demand, perseverance in research and development and unremitting efforts in technological advancement are all the way for enterprises to settle down, and they are also essential elements for battery companies to achieve long-term development.
