In 2026, Hangzhou Chauron Technology Co., Ltd. was successfully selected for Zhejiang Province’s “Golden Seed” Program, which promotes the growth of small and medium-sized enterprises through patent commercialization.
Eight years later, our pursuit of safer energy systems can be measured in real-world performance.
It is measured in 0.2 milliseconds.In the smart #5 Super Hybrid model, SPF-1 interrupts fault current within just 0.2 milliseconds — delivering Chauron’s promise of “Right Time, Full Protection” when every millisecond matters.
It is proven at 1500V / 250kA. Under extreme operating conditions in energy storage systems and high-voltage platforms, the SPF-5 series delivers reliable interruption performance — pushing the boundaries of protection for higher voltages and greater currents.
It is backed by more than 40 patents. These patents are more than certificates on paper. They have evolved into high-voltage DC fuse technologies and intelligent Pyrofuse solutions, forming a comprehensive product portfolio that supports new energy vehicles, EV charging infrastructure, renewable energy generation and storage, data centers, and hundreds of mass-production-ready SKUs.
It is also recognized in industry standards. It is reflected in standards including GB / T13539.7-2024, GB / T13539.6-2024, NB / T10329-2019, and T / CEEIA782-2024. As a member of the National Technical Committee on Fuse Standardization, Dr. Chao Dai, founder of Chauron, has transformed Chauron’s engineering practices into industry-recognized standards that contribute to the advancement of the entire sector.
A CNAS - accredited testing center, IATF16949 quality management system, and UL / TÜV / CE / 3C certifications ensure that our commitment to safety is measurable, verified, and trusted — not merely promised.
This commitment has led to today’s achievements: Chauron products have been adopted by the supply chains of more than 50 leading new energy companies, including SAIC Motor, Chery, Geely, CATL, and Sungrow. Our solutions are also delivered globally, supporting international customers such as Tata, VinFast, Stellantis, Ficosa, Valeo, and BorgWarner.
From individual components to comprehensive protection solutions for new energy power systems, we deliver more than products. We deliver trust — a trust embedded into the BOM and proven in the critical 0.2 milliseconds when protection matters most.
A “Golden Seed” represents recognition — but more importantly, it marks a new beginning.
Looking ahead, Chauron will continue advancing the boundaries of protection, tackling the challenges of higher voltages, larger currents, and increasingly complex operating environments.
