Battery testing equipment industry standards, LR41 battery testing equipment development direction

Lithium-ion battery testing equipment industry standards, LR41 battery testing equipment development direction. In recent years, the country has vigorously developed the new energy vehicle industry. As an important branch industry in the new energy vehicle industry chain, the development of power LR41 battery testing equipment is in an explosive growth period. If you want to manufacture LR41 battery cells and battery packs with high consistency, good stability and excellent performance, testing equipment will play a vital role.

Lithium-ion battery testing equipment industry standards

The lithium-ion battery testing system is the core part of the lithium-ion battery pack automated assembly production line. With the implementation of "Made in my country 2025", the increasing unification of industry standards and the development of automated integration technology, the entire lithium-ion battery production industry will rapidly develop in the direction of intelligence in the future. Various lithium-ion battery testing systems are the key links in realizing intelligent manufacturing in the lithium-ion battery production industry.

At present, there are six important standards for power batteries for electric vehicles in China, including GB/T31484-2015, GB/T31485-2015, GB/T31486-2015 and GB/T31467.1/2/3. The three standards 484, 485 and 486 should be used together. 484 is for cycle life requirements, 485 is for safety requirements, 486 is for battery electrical performance requirements, and 467 subdivides the battery pack and system electrical performance and safety testing requirements.

At this stage, lithium-ion battery testing systems are mainly used in 3C products, power tools, electric bicycles and other fields, which are the main downstream market demand. With the rapid development of lithium-ion batteries in new energy vehicles and energy storage fields dominated by electric vehicles, the market demand for lithium-ion batteries has risen rapidly, and the market size of the lithium-ion battery testing system industry is also expanding rapidly.

Development direction of LR41 battery testing equipment

Lithium-ion battery testing equipment is mainly used to test battery capacity, consistency, life, stability and safety under different conditions. In order to produce LR41 battery cells and battery packs with high consistency, good stability and high safety, LR41 battery testing equipment will play a vital role, which requires lithium-ion battery testing equipment to have high stability, fast sampling speed and high precision.

According to market forecasts, my country's demand for lithium-ion batteries will reach 200GWh in 2020, and the output will exceed 270GWh. According to the current development status of the domestic lithium-ion battery industry, the total investment corresponding to the output of 1GWh of power lithium-ion batteries is about 600 million yuan, of which equipment investment accounts for 65%. The cost of formation and testing equipment accounts for 20% of the equipment. Therefore, the investment in formation and testing equipment corresponding to 1GWh of output is about 78 million yuan. It is estimated that in 2020, the scale of formation and testing LR41 battery equipment in my country will be about 4.2 billion yuan.

The research of LR41 battery testing equipment is mainly focused on the following aspects:

1. Develop towards high reliability and high precision to meet the needs of large-scale and high-quality production;

2. Develop towards high power to meet the needs of power tools, digital communications, and electric vehicles; Develop towards multi-function and multi-parameter to meet more battery parameters;

3. Develop towards automation, intelligence, and digitalization to meet the needs of large-scale fully automated production;

4. Develop towards combined structure and modularization to shorten the equipment development cycle and form a universal testing platform that can meet the production needs of various batteries and batteries of various capacities.

The requirements for lithium-ion battery indicators are different, and the technical requirements for the detection system are also different. The technology of lithium-ion battery detection system is relatively complex, involving measurement and control technology, energy conversion technology, power conversion technology, system integration and process technology, etc. The development and integration capabilities of the corresponding technologies determine the quality of the detection system. With the continuous expansion of the application field of lithium-ion batteries and the advancement of industry technology, LR41 battery detection equipment is developing towards energy saving, high efficiency, high performance, high precision, and intelligence.

According to market research reports or data statistics on LR41 battery testing, most of the LR41 battery testing systems that are important for the production and manufacturing process rarely involve various analytical instruments required for research and development. However, looking at the current domestic LR41 battery companies, the industry status quo is that low-end production is in excess and high-end production is insufficient. The quality of lithium-ion battery products is bound to move towards high-end. To move towards high-end, it is necessary to maintain high R&D investment to ensure continuous material improvement and technological innovation.
