In the high-end manufacturing and global expansion of new energy lithium batteries, metal foreign object control is a core defense line for ensuring battery safety, performance, and lifespan. As a leading enterprise in the global new energy vehicle and battery industry, BYD has established extremely stringent standards for cleanliness control across its entire supply chain. Recently, the FASMEI cleanliness analysis system successfully secured a procurement order from BYD, not only being fully deployed in core domestic production bases such as Qinghai, Yancheng, and Anhui, but also exported to BYD's Hungarian base as part of its global expansion. It is specifically used for precise control of metal foreign objects throughout the entire lithium battery production process. With its superior performance surpassing German equipment, it lays a solid quality foundation for the high-quality advancement of BYD's global production capacity.

During the lithium battery production process, even trace amounts of metal foreign objects can cause safety risks such as internal micro-short circuits and thermal runaway. This is especially critical for BYD's high-end lithium battery products produced on a global scale, where the accuracy and efficiency of metal foreign object control directly impact its global market reputation. The FASMEI cleanliness analysis system is specifically customized for the metal foreign object control needs of the lithium battery industry. Its core advantage lies in its performance, which comprehensively surpasses similar German equipment: equipped with advanced high-precision scanning and recognition algorithms, it can achieve precise capture and efficient differentiation of tiny metal particles larger than 5μm, with superior detection accuracy and stability; it also boasts ultra-fast analysis speed, perfectly matching the large-scale mass production testing pace of BYD's various bases, allowing for rapid batch sample testing and significantly improving production efficiency.

The simultaneous deployment of the FASMEI cleanliness analysis system in multiple BYD domestic bases and its export to Hungary fully demonstrates its wide adaptability to different production scenarios and its global service capabilities. For the differentiated needs of BYD's domestic and international bases, FASMEI provides customized solutions: domestic bases are adapted to large-scale mass production testing needs, optimizing the multi-station collaborative capabilities of the equipment; the Hungarian base matches international production standards, providing a fully English operation interface and international technical support. At the same time, FASMEI has established a professional global service team to provide rapid response installation and commissioning, operation training, and subsequent maintenance services for each base, ensuring efficient and stable operation of the equipment worldwide. Compared to German equipment, this system also offers significant cost-effectiveness advantages, helping BYD optimize the cost structure of its global production capacity. This in-depth collaboration with BYD is a significant milestone for FASMEI's cleanliness analysis system in the high-end market and global expansion of the lithium-ion battery industry. It demonstrates that domestically produced testing equipment now possesses the technical capabilities to compete with top international brands. In the future, FASMEI will continue to focus on addressing the pain points of cleanliness control in the lithium-ion battery industry, iteratively upgrading its product technology and global service system. Through more efficient, precise, and intelligent cleanliness solutions, FASMEI will support leading companies like BYD in deepening their global presence and injecting strong momentum into the high-quality global development of the new energy industry.
