With the advancement of the global carbon peaking and carbon neutrality transformation, the lithium-ion battery industry has entered a new round of development cycle. Ultimate quality, ultimate energy saving, ultimate efficiency improvement, and ultimate cost reduction have become important means for lithium-ion battery companies to enhance their core competitiveness and global discourse power.

According to the forecast of the survey agency, by 2025, the market size of China's lithium-ion battery formation and grading lines is expected to reach 25 billion RMB. However, the energy consumption of formation and grading equipment accounts for about 40% of the energy consumption of the entire line, which is one of the links with the highest production costs. With the increase of production capacity, it has become urgent to solve the problem of energy consumption of formation and grading equipment.

Lyric, as an excellent global high-end intelligent equipment company, focuses on the weak points of energy saving and emission reduction in the production process of customers. Lyric continues to increase investment in research and development. In 2021, Guangdong Shunshi Measurement and Control Equipment Co., Ltd. was established. The self-developed new energy post-processing system with the integrated serial formation and grading machine is working hard in the formation and grading of pouch cell, prismatic cell, and large cylindrical battery cells. Sunshi is now equipped with more than 20,000 square meters of intelligent manufacturing workshops and more than 3,000 square meters of research and development laboratory, and built two PCBA automatic production lines (including coating), which can meet the needs of multiple projects at the same time. Customers are spread all over the world and we have established long-term and stable cooperative relations with leading enterprises such as ATL,BYD, Microvast, SVOLT Energy, Ganfeng Lithium, and Sinochem Yangzhou. Relying on a strong technical research and development team, we have applied for more than 230 key technology patents in the serial formation and grading technology. We have the integrated development capabilities of software and hardware, and can provide customers with a full range of one-stop value-added services. The serial formation and grading technology independently developed by Shunshi Measurement and Control Equipment Co., Ltd. has high energy feedback efficiency, high dynamic response speed, high test accuracy, high integration, independent channel control technology, and comprehensive innovation and optimization of hardware and software to solve the problem of battery routine formation, like poor safety, low safety, waste of energy and high cost, enabling various battery production line applications such as cylindrical, prismatic, blade, and pouch cells, etc., to help customers build advanced, high-safety, energy-saving smart factories.”

High feedback efficiency structure to promote "zero carbonization" of lithium-ion battery production

In the new energy post-processing system of Shunshi Measurement and Control, the energy discharged by the battery can be directly used by the battery that needs to be charged, and can also be directly fed back to the grid, which can realize intelligent scheduling of peaks and valleys, and the feeding efficiency is ≥85%, which greatly reduces power consumption. Electricity cost; Its cable integrated layout enhances the reliability of equipment while saving energy and reducing consumption by more than 20%, which greatly reduces cable cost and cable-caused energy consumption loss. The integrated formation and grading machine independently developed by Shunshi Measurement and Control can ensure the current consistency through the series circuit, realize the continuous flow and stable bypass of the single battery cell, the impact current of the bypass process is < 5 % F.S., the impact time is < 50 ms, and the production data process monitoring, data integration and sharing, and traceability of the whole process. Compared with the traditional split-type parallel power supply, a standard production line saves more than 5.5 million RMB/year in comprehensive electricity costs, which is equivalent to reducing more than 7,000 tons of CO2 emissions.

Combination of software and hardware, enjoying digital intelligence

In order to better meet customer needs, the equipment of Sunshi Measurement and Control can realize digital intelligence through the combination of software and hardware.

Each channel of the production line can be started independently, and its utilization rate is > 99.9 %, with high reliability and independent control capabilities; its modular design enables quick installation and quick replacement of compatible components; rich software interfaces can be expanded and combined according to different needs of customers , more than 3000 channel stable communication; hardware protection functions are complete, multiple protection design, can monitor equipment performance, battery status, prevent falling, with high security. Sunshi Measurement and Control can provide a complete set of technical services from the whole line program planning, the core process special machines to the construction of formation and grading automation production line, and the informatization and intelligence of the whole plant. We let customers enjoy digital intelligence while realizing the concept of environmental protection and energy saving.

Strive for excellence and empower intelligent manufacturing of various battery cells

Modular design is adopted for the entire production line stations of pouch, prismatic, blade, cylindrical and other battery cells to achieve standardization of changeover parts of and changeover process, saving time for changeover and maintenance. And through serial coding, the status of parts can be dynamically tracked throughout the whole process; data integration and sharing, flexible interaction with MES, showing agility and intelligence; multiple safety protection designs such as structural secondary protection, power-off and air-off protection, insulation protection, and electrical program interlock mode, improving equipment safety performance. Having a professional thermal simulation team drives the optimization design of equipment and power supply layout, which can improve the reliability of the heat dissipation layout inside the power cabinet, improve the temperature uniformity of the battery cell production environment, and help the consistency of battery cell production. At present, Shunshi Measurement and Control has successful delivery cases of post-processing systems for pouch, prismatic, blade and large cylindrical cells to leading customers in the industry, being unanimously recognized by many battery customers at home and abroad.

In the future, Shunshi Measurement and Control will continue to focus on the development needs of the new energy industry, adhere to independent innovation, continue to increase investment in research and development, continue to use high-tech technology to empower customers with intelligent manufacturing, and jointly promote the "zero carbonization" of the new energy industry.
